Two formulations of sweets based on jujube, baobab fruit powder and sweet potato puree were produced, and their nutritional values and sensory properties such as taste, smell, color and acceptability were assessed. The formulation containing the most jujube powder, baobab fruit and sweet potato puree gave the best nutritional value. The sweets are rich in calcium (259.80 mg/100 g), magnesium (67.98 mg/100 g), potassium (782.04 mg/100 g), vitamin C (32.37 mg/100 g), iron (6.45 g mg/100 g) and zinc (0.97 mg/100 g). Sensory tests on the two formulations showed acceptability scores ranging from 81.26% to 84.58%, well above the minimum acceptable threshold. Candies with jujube, baobab fruit powder and sweet potato puree could be an alternative for preventing micronutrient deficiencies.展开更多

Methods： Nutritional risk of 99 leukemia patients was screened with NRS2002 before and after HSCT. The ^（2 test was applied to compare the risk differences between groups such as age, gender and matching degree, while the differences of other enumeration data, such as recent （1-3 months） weight loss, reduced food intake within one week and BMI, were compared by continuity correction. Results： Of the 99 leukemia patients, 22 cases （22.2 %） had nutritional risk before HSCT, while all patients had nutritional risk after ttSCT; there is no significant difference in nutritional risk between male and female, and patients of less than 30 years old, not-full matched, recent （1-3 months） weight loss, reduced food intake within a week or BMI 〈18.5 were more likely to have nutritional risk; and 77 cases （77.8%） had weight loss, among which 49 patients （63.6%） had more than 5% weight loss within one month. Conclusions= This study showed that leukemia patients should receive the nutritional risk screening conventionally before and after HSCT, and NRS2002 was only appropriate for nutritional risk screening before HSCT. More attention should be paid to the patients less than 30 years old or not-full matched. Weight change was one of the important nutritional indicators for patients after HSCT.展开更多

Methods A cross-sectional study of 1,343 elderly inpatients was conducted in the Chinese PLA General Hospital. Nutrition Risk Screening（NRS 2002） and Subjective Global Assessment（SGA） were administered. Anthropometric measurements and blood biochemical indicators were obtained using standard techniques. The gender-and age-specific receiver operating characteristic（ROC） curves were constructed to evaluate the HGS for nutritional status by SGA and NRS 2002. Sensitivity, specificity, and areas under the curves（AUCs） were calculated. Results According to NRS 2002 and SGA, 63.81% of elderly inpatients were at nutritional risk and 28.22% were malnourished. Patients with higher HGS had an independently decreased risk of malnutrition and nutritional risk. The AUCs varied between 0.670 and 0.761. According to NRS 2002, the optimal HGS cut-points were 27.5 kg（65-74 years） and 21.0 kg（75-90 years） for men and 17.0 kg（65-74 years） and 14.6 kg（75-90 years） for women. According to SGA, the optimal HGS cut-points were 24.9 kg（65-74 years） and 20.8 kg（75-90 years） for men and 15.2 kg（65-74 years） and 13.5 kg（75-90 years） for women. Conclusion Elderly inpatients had increased incidence of malnutrition or nutritional risk. HGS cut-points can be used for assessing nutritional status in elderly inpatients at hospital admission in China.展开更多

Intramyocellular lipids （IMCL） were significantly reduced in the tibialis muscle （-28.2%）. Decreases in both IHCL （-39.9%） and soleus IMCL （-12.2%） content were also observed, although these were not significant. Several individuals showed dramatic decreases in IHCL, while others paradoxically showed increases in IHCL content. Changes in body composition were accompanied by improvements in certain liver function tests： serum aspartate aminotransferase （AST） and alanine aminotransferase （ALT）. Significant correlations were found between decreases in IHCL and reductions in both intra-abdominal and abdominal subcutaneous AT. Improvements in liver function tests were associated with reductions in intra-abdominal AT, but not with changes in IHCL. CONCLUSION： This study shows that even a very modest reduction in body weight achieved through lifestyle modification can result in changes in body fat depots and improvements in LETs.展开更多

Four types of leisure ST and three types of PA selfreported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components.Results For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio(OR) 1.3, 95% confidence interval(CI) 1.1–1.6, P < 0.001;OR 1.4, 95% CI1.2–1.8, P < 0.001, respectively]. The MetS risk in the computer time > 7 hours/week(h/w) group was higher than that in the < 7 h/w group in(OR 1.5, 95% CI 1.2–1.9). Higher levels of moderate-to-vigorousintensity physical activity(MVPA) and total PA were associated with a lower MetS risk(OR 0.7, 95% CI0.6–0.9, P < 0.001;OR 0.8, 95% CI 0.7–0.9, P < 0.001, respectively). For the joint effects, compared with those reporting the lowest level of total leisure ST(< 14 h/w) and the most active tertile of MVPA(≥ 61.0 MET-h/w), participants reporting the most total leisure ST(≥ 35 h/w) and the lowest level of MVPA(0 MET-h/w) had the highest odds of MetS(OR 2.0;95% CI 1.4–2.7). Except for people reporting ST(14–21 h/w) within the most active tertile of MVPA, the associations in all other groups were significant.With the increase of TV time and decreased MVPA, the odds of MetS almost showed a curve acceleration.Conclusions MVPA and total PA have independent preventive effects, and sedentary behavior(mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults.展开更多

More recently, the problem has gained notoriety in nutritional sciences. COI with industry could bias study conclusions in the context of research activities and scientific publications on nutritional sciences. The issue of COI in nutritional sciences deserves more attention and requires careful analyses as biased information can negatively impact the development of dietary guidelines and, ultimately, population health. Decision-making is generally based on available, published evidence, but when the results are ambivalent, it is easier to opt for the status quo and ask for more studies. Readers might wonder if research is subsidized by industry as a counterbalancing strategy based on levels of evidence-only to slow down eminent positions and/or legislation on the food sector? How can this problem be overcome without producing paranoia and Mc Carthyism while trying to be as methodological as possible?展开更多

It is commonly believed that iron deficiency is the main cause of anemia in China. Iron fortified soysauce is used to prevent anemia. Findings from Jiangsu Nutrition Study suggest that diet is related to anemia in this region. However,iron deficiency is not the main cause. Micronutrients other than iron(e.g.,riboflavin) need to be considered in the prevention of anemia in the region.展开更多

Master level nutrition programs exist in the U.S., but are not standardized or accredited unlike four-year degrees. Academic requirements for nutrition graduate programs vary regionally across the nation. Objective: To 1) quantify and describe the availability of Master level nutrition programs regionally;and 2) examine the current M.A. and M.S. program requirements for a nutrition graduate degree in the U.S. Methods: Nutrition graduate programs (n = 201) were analyzed and compared by geographical region. Data were collected between August 2017 and May 2018. Inclusion criteria were defined as: nutrition graduate programs listed in the American Society of Nutrition (ASN) database that had a nutrition graduate program website. Descriptive statistical analysis measured evaluated variables. Results: A total of 201 nutrition graduate programs in the U.S. were identified. The title of the programs was categorized into 29 main themes. The most common nutrition graduate program title was a M.S. in Nutrition, 55 institutions (27.4%). A total of 181 institutions offered a M.S. with a required thesis, whereas 95 offered a M.S. with a non-thesis option, and only eight offered a M.A. Region 3-South offered the highest number of nutrition graduate programs (66), followed by region 2-Midwest with 49 programs, region 1-Northeast offered a total of 46 programs, and 37 programs were offered in region 4-West. Conclusion: In 2024, as part of the RD eligibility criteria, it will be required that students possess a master’s degree. To date, only one master’s program in the U.S. is accredited, which assures the student a measure of confidence of program rigor and accountability. Dietitians’ three major professional concerns: respect, recognition and rewards are predicated on rigorous educational programs that meet ACEND standards. It is unlikely that all U.S. master level programs will be accredited by 2024.展开更多

This study evaluated the effect of hypo-calories with micronutrients of pre-operative peripheral parenteral nutrition support (PPPN) for rectal cancer patients. Retrospective cross sectional study method was used to investigate. We screened rectal cancer patients past year pre-operative with malnutrition risk from our cancer database and divided into 2 groups, received or not received PPPN and compared the post-operative outcomes. The results showed that the post-operative serum albumin of the 25 patients received PPPN averaged 2.5 ± 0.32 g/dl;significantly better than those of the 15 patients not received PPPN (non-PPPN), which averaged 1.92 ± 0.42 g/dl. The first ambulatory time required 3.0 ± 0.8 days for the PPPN, significantly shorter than those for the non-PPPN, which averaged 4.9 ± 2.4 days. Post-operative hospital days for the patients received PPPN were 18.2 ± 10.5 day, also significantly fewer than the non-PPPN, which averaged 33.7 ± 20.0 day.

Along with the transitions of social and economic development,dietary patterns and physical activity and life-styles,the prevalence of childhood overweight and obesity has increased at an astonishing rate in the past ...Along with the transitions of social and economic development,dietary patterns and physical activity and life-styles,the prevalence of childhood overweight and obesity has increased at an astonishing rate in the past decades,and has become one of the most serious public health challenges.Meanwhile,the stunting rate has declined with slowly pace,while millions of young lives are still be threatened by wasting all over the word.The present situation of Double Burden of Malnutrition should be recognized clearly and addressed seriously,which refers to,the common presence of both obesity and underweight in the same populations,communities and even families.In order to provide guidance on the appropriate assessment and management of infants and children presenting to primary health-care facilities,to reduce the risk of overweight and obesity among children,the Guideline Assessing and Managing Children at Primary Healthcare Facilities to Prevent Overweight and Obesity in the Context of the Double Burden of Malnutrition was developed and released by WHO in 2017 using the procedures outlined in the WHO handbook for guideline development.The WHO Guideline(2017)is intended primarily for use in low-and medium-resource settings where both under-nutrition and obesity are prevalent.In this guideline,there are three prioritized speci c areas and questions for infants and children presenting to primary health-care facilities:anthropometric assessment,care of infants and children with acute or chronic malnutrition,and care of children who are overweight or obese.It is recommended that for infants and children aged<5 years presenting primary health-care facilities,weight and length/height should be measured and evaluate adequately,general nutrition and physical activity counselling should be provided for related caregivers and families,identi cation and appropriate management plan should be developed at primary health-care level.The discrepancies of the recommendation on the three prioritized areas in di erent guidelines are compared in this paper.All the related guidelines emphasize the important of anthropometric measurement and monitor of growth for primary care workers and suggest dietary and physical activity counselling for obese people.Almost all the guidelines provide recommendations on breastfeeding and continued feeding counselling from the aspect of improving the status of acute or chronic malnutrition.The setting condition should be carefully considered when taking the guidelines of di erent organizations and countries into application.展开更多
文摘BACKGROUND Hashimoto’s thyroiditis(HT)is an autoimmune dysfunction caused by genetic and environmental changes that attack the thyroid gland.HT affects approximately 2%to 5%of the population,being more prevalent in women.It is diagnosed through a blood test(anti-thyroid peroxidase).Pharmacological treatment consists of daily administration of the synthetic hormone levothyroxine on an empty stomach.The most common signs and symptoms are:Tissue resistance to triiodothyronine T3,weight gain,dry skin,hair loss,tiredness/fatigue,and constipation,and nutritional therapy appears to help reduce these symptoms.AIM To analyze nutritional interventions for treating HT.METHODS This is an integrative review of original studies on nutritional interventions for treating Hashimoto’s disease.Articles were searched in the MEDLINE/PubMed and Latin American and Caribbean Literature on Health Sciences(LILACS)databases via virtual health library,using controlled vocabulary and free terms.A total of 70 articles were found:67 from PubMed and 3 from LILACS.After exclusions,9 articles met the eligibility criteria,including dietary interventions for maintaining and restoring the patient’s quality of life.RESULTS The reviewed articles evaluated the nutritional treatment of HT through supplementation of deficient micronutrients,anti-inflammatory diets,gluten-free diets,exclusion of foods that cause food sensitivities,lactose-free diet,paleo diet,and calorie restriction diets.However,some results were controversial regarding the beneficial effects of HT.CONCLUSION In general,it was observed that nutritional interventions for HT are based on the recovery of micronutrient deficiencies,treatment of the intestinal microbiota,diet rich in foods with anti-inflammatory properties,lifestyle changes,and encouragement of healthy habits.
文摘Increasing access to locally produced, safe, nutritious and affordable complementary foods is essential to combat micronutrient deficiencies in young children in low- and middle-income countries. Two formulations of sweets based on jujube, baobab fruit powder and sweet potato puree were produced, and their nutritional values and sensory properties such as taste, smell, color and acceptability were assessed. The formulation containing the most jujube powder, baobab fruit and sweet potato puree gave the best nutritional value. The sweets are rich in calcium (259.80 mg/100 g), magnesium (67.98 mg/100 g), potassium (782.04 mg/100 g), vitamin C (32.37 mg/100 g), iron (6.45 g mg/100 g) and zinc (0.97 mg/100 g). Sensory tests on the two formulations showed acceptability scores ranging from 81.26% to 84.58%, well above the minimum acceptable threshold. Candies with jujube, baobab fruit powder and sweet potato puree could be an alternative for preventing micronutrient deficiencies.

文摘University students,transitioning from adolescence to adulthood,are at a critical stage where dietary habits and health behaviors are established,influencing long-term health outcomes.This study aimed to assess the dietary intake and nutritional awareness of a population of Chinese university students(n=833),comparing their consumption with national dietary guidelines and reference intakes,while exploring subgroup differences.Results indicated that males had significantly higher amounts of most food categories compared to females.Except for whole grains and legumes,ethnic minorities had lower compliance with the recommended intakes for several food categories compared to Han Chinese.Han males consumed more energy,protein,and fat than their ethnic minority counterparts.Obese participants showed higher protein and fat intake compared to those with normal body mass index(BMI).Additionally,BMI-related trends in macronutrient contributions showed that protein and fat contributed more to the total energy intake of individuals with higher BMI.Han individuals also had higher energy contributions from protein and fat and lower carbohydrate contributions compared to ethnic minorities.Nutrient intake was generally below recommended levels,with low proportions of participants meeting the recommended intake for vitamin A,C,calcium and dietary fiber.High proportions of participants exceeded the tolerable upper intake levels for iron and manganese.Nutritional awareness scores were also significantly higher among Han students,as well as those with higher BMIs and higher income levels.This study highlights significant disparities in dietary intake and nutritional awareness among Chinese university students,with variations across sex,ethnicity,BMI,and income categories.

文摘Deep phenotyping and genetic characterization of individuals are fundamental to assessing the metabolic status and determining nutrition-specific requirements.This study aimed to ascertain the utmost effectiveness of personalized interventions by aligning dietary adjustments with both the genotype and metabolotype of individuals.Therefore,we assessed here the usefulness of a polygenic score(PGS)characterizing a potential pro-inflammatory profile(PGSi)as a nutrigenetic tool to discern individuals from the Danish PREVENTOMICS cohort that could better respond to precision nutrition(PN)plans,specifically targeted at counteracting the low-grade inflammatory profile typically found in obesity.The cohort followed a PN plan to counteract the pro-inflammatory profile(PNi group)or generic dietary recommendations(Control)for 10 weeks.PGSi was applied for genetic stratification(Low/High).The effects of the intervention on anthropometrics and biomarkers related to inflammatory profile and carbohydrate metabolism were assessed.Around 30%of subjects had a high genetic predisposition to pro-inflammatory status(high-PGSi).These individuals demonstrated the most effective response to the dietary plan,experiencing improved body composition,with significant decreases in body weight(∆:-4.84%;P=0.039)and body fat(∆:-4.86%;P=0.007),and beneficial changes in pro-and anti-inflammatory biomarkers,with significant increases in IL-10(∆:71.3%;P=0.025)and decreases in TNF-α(∆:-3.0%;P=0.048),CRP(∆:-31.1%),ICAM1(∆:-5.8%),and MCP1(∆:-4.2%)circulating levels,compared to low-PGSi individuals.Both phenotypic and genetic stratification contributed to a better understanding of metabolic heterogeneity in response to diet.This approach allows for refinement of the prediction of individual requirements and potentially for better management of obesity.
文摘Objective:It was conducted to evaluate the susceptibility to ON(orthorexia nervosa)in the students of the nutrition and dietetics department according to the variables of gender,age and BMI(body massındex).Subjects and Methods:The research covers the students of Marmara University Faculty of Health Sciences,Department of Nutrition and Dietetics in September-October 2017-2018 academic year.The data were collected by survey method.Socio-demographic characteristics and anthropometric measurements of the participants were questioned.EAT-40(Eating Attitude Test),ORTO-15 test and MOCI(Maudsley Obsessive Compulsive Inventory)were used in the study.It was evaluated with SPSS(The Statistical Package for The Social Sciences)21.0 program.Results:205 people participated in the study.EAT-40 scores were found to be≤20 in 94%of the women and 95.2%of the men in the study.The EAT-40 score is≥21 in 6%of women and 4.8%of men in the study(p=0.646>0.05).The ORTO-15 score of 72.3%of women and 71.4%of men is≤40(p=0.934>0.05).EAT-40 average is 10.25±1.10 in underweight.It was found to be 9.21±0.42 in normals and 8.23±0.76 in slightly obese subjects(p=0.758>0.05).ORTO-15 average of those with BMI≤18.49 kg/m2 is 39.59±0.54;Those with 18.50-24.99 kg/m2 were found to be 38.30±0.25 and those with 25.00-29.99 kg/m2 were found to be 39.54±0.75(p=0.098>0.05).As the EAT-40 score increased,the ORTO-15 score decreased.It shows a negative,statistically significant difference between EAT-40 and ORTO-15 scores(p=0.00<0.05).Conclusion:It was concluded that orthorexic tendency is common(72.2%)in nutrition dietetic students,and ON is associated with BMI and EAT-40 scores.In terms of ON,it would be beneficial to conduct comprehensive international studies and determine DSM(Diagnostic and Statistical Manual of Mental Disorders)diagnostic criteria.

文摘Objective This study aims to investigate the joint associations of sarcopenia and social isolation with mortality risk.Methods Using data from the Chinese Longitudinal Healthy Longevity Survey(CLHLS)and the UK Biobank,sarcopenia was diagnosed according to European and Asian Working Groups for Sarcopenia criteria.Social isolation was assessed using standardized questionnaires,including questions on solitude,frequency of social activities,contact with others,and marital status(for the CLHLS only).Results During the follow-up period,8,249 deaths occurred in the CLHLS and 26,670 deaths in the UK Biobank groups.While no significant interaction was observed between sarcopenia and social isolation in predicting all-cause mortality in the CLHLS cohort,the association between social isolation and mortality was stronger among individuals with sarcopenia in the UK Biobank(P-interaction=0.03,relative risk due to interaction:0.23,95%confidence interval[CI]:0.06–0.41).Further joint analyses showed that participants with sarcopenia and high levels of social isolation had the highest mortality risk(hazard ration[HR]:1.99;95%CI:[1.74–2.28]in the CLHLS and 1.69[1.55–1.85]in the UK Biobank)compared to those without either condition.Conclusion The combination of social isolation and sarcopenia synergistically increases the risk of mortality in middle-aged and older adults across diverse populations.
文摘Objective： To discuss whether nutritional risk screening 2002 （NRS2002） is appropriate for nutritional risk screening for leukemia patients before and after hematopoietic stem cell transplantation （HSCT）, and whether there are risk differences in other conditions, such as age, gender and matching degree; to find the methods and indicators of nutritional risk screening for these patients before and after HSCT, in order to give timely intervention to guarantee the successful completion of the entire transplantation process. Methods： Nutritional risk of 99 leukemia patients was screened with NRS2002 before and after HSCT. The ^（2 test was applied to compare the risk differences between groups such as age, gender and matching degree, while the differences of other enumeration data, such as recent （1-3 months） weight loss, reduced food intake within one week and BMI, were compared by continuity correction. Results： Of the 99 leukemia patients, 22 cases （22.2 %） had nutritional risk before HSCT, while all patients had nutritional risk after ttSCT; there is no significant difference in nutritional risk between male and female, and patients of less than 30 years old, not-full matched, recent （1-3 months） weight loss, reduced food intake within a week or BMI 〈18.5 were more likely to have nutritional risk; and 77 cases （77.8%） had weight loss, among which 49 patients （63.6%） had more than 5% weight loss within one month. Conclusions= This study showed that leukemia patients should receive the nutritional risk screening conventionally before and after HSCT, and NRS2002 was only appropriate for nutritional risk screening before HSCT. More attention should be paid to the patients less than 30 years old or not-full matched. Weight change was one of the important nutritional indicators for patients after HSCT.
文摘Objective To assess nutritional status and define gender-and age-specific handgrip strength（HGS） cut-point values for malnutrition or nutritional risk in elderly inpatients. Methods A cross-sectional study of 1,343 elderly inpatients was conducted in the Chinese PLA General Hospital. Nutrition Risk Screening（NRS 2002） and Subjective Global Assessment（SGA） were administered. Anthropometric measurements and blood biochemical indicators were obtained using standard techniques. The gender-and age-specific receiver operating characteristic（ROC） curves were constructed to evaluate the HGS for nutritional status by SGA and NRS 2002. Sensitivity, specificity, and areas under the curves（AUCs） were calculated. Results According to NRS 2002 and SGA, 63.81% of elderly inpatients were at nutritional risk and 28.22% were malnourished. Patients with higher HGS had an independently decreased risk of malnutrition and nutritional risk. The AUCs varied between 0.670 and 0.761. According to NRS 2002, the optimal HGS cut-points were 27.5 kg（65-74 years） and 21.0 kg（75-90 years） for men and 17.0 kg（65-74 years） and 14.6 kg（75-90 years） for women. According to SGA, the optimal HGS cut-points were 24.9 kg（65-74 years） and 20.8 kg（75-90 years） for men and 15.2 kg（65-74 years） and 13.5 kg（75-90 years） for women. Conclusion Elderly inpatients had increased incidence of malnutrition or nutritional risk. HGS cut-points can be used for assessing nutritional status in elderly inpatients at hospital admission in China.

文摘AIM： To assess the effectiveness of the current UK clinical practice in reducing hepatic fat （IHCL）.METHODS： Whole body MRI and IH MRS were obtained, before and after 6 mo nutritional counselling, from liver, soleus and tibialis muscles in 10 subjects with non-alcoholic fatty liver disease （NAFLD）.RESULTS： A 500 Kcal-restricted diet resulted in an average weight loss of 4% （-3.4 kg,） accompanied by significant reductions in most adipose tissue （AT） depots, including subcutaneous （-9.9%）, abdominal subcutaneous （-10.2%） and intra-abdominal- AT （-11.4%）. Intramyocellular lipids （IMCL） were significantly reduced in the tibialis muscle （-28.2%）. Decreases in both IHCL （-39.9%） and soleus IMCL （-12.2%） content were also observed, although these were not significant. Several individuals showed dramatic decreases in IHCL, while others paradoxically showed increases in IHCL content. Changes in body composition were accompanied by improvements in certain liver function tests： serum aspartate aminotransferase （AST） and alanine aminotransferase （ALT）. Significant correlations were found between decreases in IHCL and reductions in both intra-abdominal and abdominal subcutaneous AT. Improvements in liver function tests were associated with reductions in intra-abdominal AT, but not with changes in IHCL. CONCLUSION： This study shows that even a very modest reduction in body weight achieved through lifestyle modification can result in changes in body fat depots and improvements in LETs.

文摘Objective This study aimed to determine the independent and joint associations of sedentary time(ST)and physical activity(PA) with metabolic syndrome(MetS) and its components among Chinese adults.Methods The study analyzed data from 4,865 adults aged ≥ 18 years who participated in the 2009 and2015 China Health and Nutrition Surveys(CHNS). Four types of leisure ST and three types of PA selfreported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components.Results For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio(OR) 1.3, 95% confidence interval(CI) 1.1–1.6, P < 0.001;OR 1.4, 95% CI1.2–1.8, P < 0.001, respectively]. The MetS risk in the computer time > 7 hours/week(h/w) group was higher than that in the < 7 h/w group in(OR 1.5, 95% CI 1.2–1.9). Higher levels of moderate-to-vigorousintensity physical activity(MVPA) and total PA were associated with a lower MetS risk(OR 0.7, 95% CI0.6–0.9, P < 0.001;OR 0.8, 95% CI 0.7–0.9, P < 0.001, respectively). For the joint effects, compared with those reporting the lowest level of total leisure ST(< 14 h/w) and the most active tertile of MVPA(≥ 61.0 MET-h/w), participants reporting the most total leisure ST(≥ 35 h/w) and the lowest level of MVPA(0 MET-h/w) had the highest odds of MetS(OR 2.0;95% CI 1.4–2.7). Except for people reporting ST(14–21 h/w) within the most active tertile of MVPA, the associations in all other groups were significant.With the increase of TV time and decreased MVPA, the odds of MetS almost showed a curve acceleration.Conclusions MVPA and total PA have independent preventive effects, and sedentary behavior(mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults.

文摘BACKGROUND Patients with gastrointestinal tumors often suffer from poor nutritional status during treatment.Surgery is the main treatment for these patients,but the long postoperative recovery period is often accompanied by digestive and absorption dysfunction,leading to further deterioration of the nutritional status.Early enteral nutrition support is hypothesized to be helpful in improving this situation,but the exact effects have yet to be studied in depth.AIM To observe the effect of early enteral nutritional support on postoperative recovery in patients with surgically treated gastrointestinal tract tumors,with the expectation that by improving the nutritional status of patients,the recovery process would be accelerated and the incidence of complications would be reduced,thus improving the quality of life.METHODS A retrospective analysis of 121 patients with gastrointestinal tract tumors treated in our hospital from January 2020 to January 2023 was performed.Fifty-three of these patients received complete parenteral nutrition support as the control group for this study.The other 68 patients received early enteral nutritional support as the observation group of this study.The clinical indicators comparing the two groups included time to fever,time to recovery of postoperative bowel function,time to postoperative exhaustion,and length of hospital stay.The changes in immune function and nutritional indexes in the two groups were compared.Furthermore,we utilized the SF-36 scale to compare the changes in the quality of life between the two groups of patients.Finally,the occurrence of postoperative complications between the two patient groups was also compared.RESULTS The postoperative fever time,postoperative bowel function recovery time,postoperative exhaustion time,and hospitalization time were all higher in the control group than in the observation group(P<0.05).The levels of CD3+,CD4+,immunoglobulin(Ig)A,IgM,and IgG in the observation group were significantly higher than those in the control group at 1 d and 7 d postoperatively,while CD8+was lower than in the control group(P<0.05).Total protein,albumin,prealbumin,and transferrin levels were significantly higher in the observation group than in the control group at 7 d postoperatively(P<0.05).The SF-36 scores of patients in the observation group were significantly higher than those in the control group(P<0.0001).The overall incidence of adverse reactions after the intervention was significantly lower in the control group than in the observation group(P=0.021).CONCLUSION We found that patients with gastrointestinal tumors are nutritionally vulnerable,and early enteral nutrition support programs can improve the nutritional status of patients and speed up postoperative recovery.This program can not only improve the immune function of the patient and protect the intestinal function,but it can also help to improve the quality of life of the patient.However,this program will increase the incidence of complications in patients.Caution should be taken when adopting early enteral nutrition support measures for patients with gastric cancer.The patient's condition and physical condition should be comprehensively evaluated and closely monitored to prevent possible complications.

文摘Objectives:In the hospital setting,poor dietary intake interacts with disease and represents a major and modifiable cause of malnutrition.Understanding barriers to adequate dietary intake is an important strategy to guide the development of interventions to improve nutrition intake.The aim of this study reported in this paper was to explore patient,family and health care professionals'perceptions of barriers to and enablers of adequate nutrition care and dietary intake of medical inpatients.Methods:An exploratory qualitative study design incorporating group and individual interviews of patients(n=14),their family members(n=4),and health care professionals(n=18)was undertaken.Participants were recruited pragmatically,using a mix of convenience and purposive sampling.A theoretically informed,semi-structured interview schedule was based on observations of practice and the Theoretical Domains Framework.Interviews were audio-recorded,transcribed verbatim and analysed inductively using a general inductive approach.Results:Three key themes emerged from analysing participant interviews.Siloed approaches to nutrition care reflected the diverse range of health care professionals responsible for nutrition care but who often worked in isolation from their colleagues.Competing work priorities for nurses reflected the challenge in prioritise nutrition care which was often constrained because of other care needs or work-related pressures.Helping patients to eat highlighted that nurses were often the only health care professional who would provide assistance to patients at mealtimes and lack of available staff could negatively influence patients'nutrition intakes.Conclusions:We have identified many complex and interrelated barriers which preclude adequate dietary intake in acute medical patients.These predominantly reflect issues inherent in the hospital culture and environment.Multi-faceted and sustainable interventions that support a facilitating nutrition culture and multidisciplinary collaboration,inclusive of patients and families,are needed to address these underlying barriers.
文摘Awareness of conflicts of interest(COI) in medicine began in the 1980 s. More recently, the problem has gained notoriety in nutritional sciences. COI with industry could bias study conclusions in the context of research activities and scientific publications on nutritional sciences. The issue of COI in nutritional sciences deserves more attention and requires careful analyses as biased information can negatively impact the development of dietary guidelines and, ultimately, population health. Decision-making is generally based on available, published evidence, but when the results are ambivalent, it is easier to opt for the status quo and ask for more studies. Readers might wonder if research is subsidized by industry as a counterbalancing strategy based on levels of evidence-only to slow down eminent positions and/or legislation on the food sector? How can this problem be overcome without producing paranoia and Mc Carthyism while trying to be as methodological as possible?
文摘Historically,Eastern China has the highest prevalence of anemia among adults in China. It is commonly believed that iron deficiency is the main cause of anemia in China. Iron fortified soysauce is used to prevent anemia. Findings from Jiangsu Nutrition Study suggest that diet is related to anemia in this region. However,iron deficiency is not the main cause. Micronutrients other than iron(e.g.,riboflavin) need to be considered in the prevention of anemia in the region.
文摘Background: The registered dietetic four-year degree educational structure has been intact since 1926. Master level nutrition programs exist in the U.S., but are not standardized or accredited unlike four-year degrees. Academic requirements for nutrition graduate programs vary regionally across the nation. Objective: To 1) quantify and describe the availability of Master level nutrition programs regionally;and 2) examine the current M.A. and M.S. program requirements for a nutrition graduate degree in the U.S. Methods: Nutrition graduate programs (n = 201) were analyzed and compared by geographical region. Data were collected between August 2017 and May 2018. Inclusion criteria were defined as: nutrition graduate programs listed in the American Society of Nutrition (ASN) database that had a nutrition graduate program website. Descriptive statistical analysis measured evaluated variables. Results: A total of 201 nutrition graduate programs in the U.S. were identified. The title of the programs was categorized into 29 main themes. The most common nutrition graduate program title was a M.S. in Nutrition, 55 institutions (27.4%). A total of 181 institutions offered a M.S. with a required thesis, whereas 95 offered a M.S. with a non-thesis option, and only eight offered a M.A. Region 3-South offered the highest number of nutrition graduate programs (66), followed by region 2-Midwest with 49 programs, region 1-Northeast offered a total of 46 programs, and 37 programs were offered in region 4-West. Conclusion: In 2024, as part of the RD eligibility criteria, it will be required that students possess a master’s degree. To date, only one master’s program in the U.S. is accredited, which assures the student a measure of confidence of program rigor and accountability. Dietitians’ three major professional concerns: respect, recognition and rewards are predicated on rigorous educational programs that meet ACEND standards. It is unlikely that all U.S. master level programs will be accredited by 2024.
文摘Malnutrition has been recognized as a significant risk factor for the post operated patients, especially for those patients undergoing abdominal operations. This study evaluated the effect of hypo-calories with micronutrients of pre-operative peripheral parenteral nutrition support (PPPN) for rectal cancer patients. Retrospective cross sectional study method was used to investigate. We screened rectal cancer patients past year pre-operative with malnutrition risk from our cancer database and divided into 2 groups, received or not received PPPN and compared the post-operative outcomes. The results showed that the post-operative serum albumin of the 25 patients received PPPN averaged 2.5 ± 0.32 g/dl;significantly better than those of the 15 patients not received PPPN (non-PPPN), which averaged 1.92 ± 0.42 g/dl. The first ambulatory time required 3.0 ± 0.8 days for the PPPN, significantly shorter than those for the non-PPPN, which averaged 4.9 ± 2.4 days. Post-operative hospital days for the patients received PPPN were 18.2 ± 10.5 day, also significantly fewer than the non-PPPN, which averaged 33.7 ± 20.0 day. More than 25% of the non-PPPN was infected with sepsis, while none was infected in the PPPN patients. In conclusion, this study verified the benefits of micronutrients of pre-operative peripheral parenteral nutrition support for rectal cancer patients.

文摘BACKGROUND Nutritional support for patients hospitalized in the intensive care unit(ICU)is an important part of clinical treatment and care,but there are significant implementation difficulties.AIM To introduce a modified nutritional support management system for ICU patients based on closed-loop information management and psychological counseling.METHODS The division of functions,personnel training,system construction,development of an intelligent decision-making software system,quality control,and improvement of the whole process were carried out to systematically manage nutritional support for ICU patients.RESULTS Following the implementation of the whole process management system,the scores of ICU medical staff’s knowledge,attitudes/beliefs,and practices regarding nutritional support were comprehensively enhanced.The proportion of hospital bed-days of total enteral nutrition(EN)in ICU patients increased from 5.58%to 11.46%,and the proportion of EN plus parenteral nutrition increased from 42.71%to 47.07%.The rate of EN initiation within 48 h of ICU admission increased from 37.50%to 48.28%,and the EN compliance rate within 72 h elevated from 20.59%to 31.72%.After the implementation of the project,the Self-rating Anxiety Scale score decreased from 61.07±9.91 points to 52.03±9.02 points,the Self-rating Depression Scale score reduced from 62.47±10.50 points to 56.34±9.83 points,and the ICU stay decreased from 5.76±2.77 d to 5.10±2.12 d.CONCLUSION The nutritional support management system based on closed-loop information management and psychological counseling achieved remarkable results in clinical applications in ICU patients.
文摘Along with the transitions of social and economic development,dietary patterns and physical activity and life-styles,the prevalence of childhood overweight and obesity has increased at an astonishing rate in the past decades,and has become one of the most serious public health challenges.Meanwhile,the stunting rate has declined with slowly pace,while millions of young lives are still be threatened by wasting all over the word.The present situation of Double Burden of Malnutrition should be recognized clearly and addressed seriously,which refers to,the common presence of both obesity and underweight in the same populations,communities and even families.In order to provide guidance on the appropriate assessment and management of infants and children presenting to primary health-care facilities,to reduce the risk of overweight and obesity among children,the Guideline Assessing and Managing Children at Primary Healthcare Facilities to Prevent Overweight and Obesity in the Context of the Double Burden of Malnutrition was developed and released by WHO in 2017 using the procedures outlined in the WHO handbook for guideline development.The WHO Guideline(2017)is intended primarily for use in low-and medium-resource settings where both under-nutrition and obesity are prevalent.In this guideline,there are three prioritized speci c areas and questions for infants and children presenting to primary health-care facilities:anthropometric assessment,care of infants and children with acute or chronic malnutrition,and care of children who are overweight or obese.It is recommended that for infants and children aged<5 years presenting primary health-care facilities,weight and length/height should be measured and evaluate adequately,general nutrition and physical activity counselling should be provided for related caregivers and families,identi cation and appropriate management plan should be developed at primary health-care level.The discrepancies of the recommendation on the three prioritized areas in di erent guidelines are compared in this paper.All the related guidelines emphasize the important of anthropometric measurement and monitor of growth for primary care workers and suggest dietary and physical activity counselling for obese people.Almost all the guidelines provide recommendations on breastfeeding and continued feeding counselling from the aspect of improving the status of acute or chronic malnutrition.The setting condition should be carefully considered when taking the guidelines of di erent organizations and countries into application.
