Obesity occurs as a result of an imbalance in diet (energy intake) and physical activity (energy expended), multifactorial diseases due to obesogenic environment (availability of convenience food, media influence, etc.), psycho-social factors (social support systems, cultural/environmental influence, etc.) and genetic variants. Other causes are a subgroup of etiological factors (medications, diseases, immobilization, iatrogenic procedures, monogenic disease/genetic syndrome). Obesity is measured clinically by several common tools apart from body mass index (BMI), such as waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio, and neck circumference. WC and WHR are common tools for measuring central obesity while BMI measures generalized obesity. Aims: The goal of this study is to assess the prevalence of obesity amongst health workers of David Umahi Federal University Teaching Hospital, Uburu, Ebonyi state, Southeast Nigeria and to note the prevailing factors. A reliable estimate of the prevalence of obesity among health workers will contribute to the statistics needed to sway policymakers in the country to take urgent and substantial action on the increasing prevalence of obesity, especially in the healthcare industry. Methodology: The study was carried out between May 2024 and June 2024 at the David Umahi Federal University Teaching Hospital situated in Uburu, Ohaozara Local government area of Ebonyi state, Southeast Nigeria. The questionnaire was designed using the Finnish diabetic risk score (FINDRISC). It contained basic comprehending questions on age, gender, exposure to high blood pressure medication, and anthropometric measurement amongst others. Weight was taken with a portable weighing scale and height, with a stadiometer. Both were taken with shoes and headgear removed. The BMI was calculated using the weight (kg) divided by the square of the height (m2). Result: Generally, the prevalence of obesity (>30 kg/m2) in this study was low 17.6% (38), Overweight (BMI 25 - 30), 38.9%, (84) healthy Weight, (BMI 18.5 - 24.9), 43.5% (94). The study revealed that a family history of diabetes was significantly related to higher BMI, with participants more likely to be overweight or obese (p = 0.00030). Similarly, participants with a personal history of diabetes were predominantly in the obese category (p = 0.00038). Waist circumference also showed a strong association with BMI, as larger waist measurements were more common among obese individuals (p = 9.2 × 10−8). In contrast, the analysis found no significant relationships between BMI and age, gender, high blood pressure, or exercise habits. Conclusion: The socio-demographic determinants of obesity in this study were gender, age < 45 years and exposure to exercise. These determinants should form the areas of focus for interventions such as health education and the design of work environments as environments designed to promote physical activities while working will reduce the prevalence of obesity in tertiary institutions.展开更多

Method: The observational study was conducted at a public tertiary hospital in Zhejiang, China, from September 2018 to March 2021. A total of 58 HH observers were trained to conduct a direct observation on the HH behaviors of personnel in the hospital amongst the health care workers. We have observed over 9000 hand hygiene opportunities. The collected data were classified according to time factors, department parameters, and profession conduct of the observed. Hand hygiene (HH) compliance rates were calculated for each category, and a chi-square test was used to analyze differences of the HH compliance rates. Furthermore, binary logistic regression was used for multivariate analysis in each of the hand hygiene moments. Results: The HH compliance rates of HCWs were statistically different before and after the Corona Virus Disease 2019 (COVID-19) pandemic, in the morning and the afternoon, this was observed per parameters stated into objectives on weekdays vs non weekdays. And we found that HH compliance rates drop off a cliff from weekdays to non-weekdays. Conclusions: COVID-19, departments, professions, and weekdays were all factors that influence HH compliance amongst HCWs. However, the influencing factors were not all present in every HH behavior, and had different intensities of influence on HH compliance amongst the HCWs. These findings provide some reference for us to propose improvement measures.展开更多

Methods: A cross-sectional study was conducted among IFFWs sampled from several joint- venture and private factories in Dongguan city. Results: Out of 175 sampled workers, 165 qualified for inclusion and the median age was 22. The results showed that the IFFWs had low levels of knowledge about HIV/AIDS, and held many misconceptions. Thirty three of 76 (43.4%) unmarried IFFWs had premarital sexual contact, and more than half of these contacts were one-night stands (54.5%) . More than one quarter of the women(25.9%) never used condoms, 49.4% sometimes used condoms and 24.7% used condoms every time. Twenty-eight women (31.8%) had an induced abortion because of an unexpected pregnancy. Fourteen (14.9%) had been infected with STDs, and four IFFWs(2.8%)had tried drugs before the interview. Conclusion: In order to empower the IFFWs in the city to protect themselves from HIV, and to contain the rapid spread of HIV in our province, targeted HIV/ AIDS health promotion programs should be urgently implemented among IFFWs in Dongguan city. The programs should be designed to improve the knowledge of HIV, to promote condom use, and to reduce risky behaviors.展开更多

[Method] Considering the nectar secretion characteristics of major and auxiliary nec-tariferous plants, six Apis mel ifera colonies were selected for measure the number of eggs, larvae, pupae and adult bees from Jan. to Dec. in 2012; based on that, their annual change curves were also plotted. [Result] The results showed that there were three peaks of the total number of A. mel ifera workers throughout the year：the first occurred on May 15th, with bees developed into an ideal population for col-lecting pomegranate nectar, and the second and third peaks occurred on July 15th and Oct. 15th, respectively, with bees developed into an ideal population for col ect-ing E. ciliate （Thuab） Hyland. [Conclusion] Prevention of Varroa jacobsoni should be carried out with two or more types of acaricides at the late nectar flow stages of the two nectariferous plants（pomegranate and E. ciliate （Thuab） Hyland） when there was a nectar deficiency. Prevention of Tropilaelaps clareae should be timely per-formed with sublimed sulfur in conjunction with acaricides. This study provides a theoretical basis for the high-quality and high-yielding production of honey, as wel as for the product safety.展开更多

On the basis of fully explaining peasant workers’ transformation to urban residents, a method for measuring its process has been advanced and then confirmed with the data of March in 2005 from surveys to peasant workers in Wuhan. Finally, the suggestions of acceler-ating peasant workers’ transformation to urban residents to pro-mote the construction of a harmonious society have been drawn from the analysis.展开更多

Research on thefrequency and determinants of condom use in com-mercial sex workers and their clients is important inincreasing condom use and reduction of the STD/HIV.Burden. Objectives: To establish the frequency of and fac-tors related to intention to use condoms and actualcondom use in commercial sex contacts and to deter-mine the differences in condom use between sex work-ers and clients.Methods: Incarcerated commercial sex workers(ICSW) and male STD clinic attendees were recruitedinto a cross-sectional study to obtain data on the fre-quency and factors associated with intention to usecondoms and condom use in commercial sexual con-tacts with an interviewer-administered questionnaire.Consistent condom use in ICSWs and never usingcondoms in male STD clinic attendees were analyzedusing univariate and multivariate logistic regressionmodels. Results: The frequency of reported consistent in-tention to use condoms and reported actual condomuse was 62% and 50.6%, respectively among 158ICSWs. For male STD clinic attendees, the propor-tion of reported consistent intention to use condomsand reported actual condom use was 10% and 20.7%,respectively. The factors positively influencing theconsistent intention to use condoms were pregnancypreventing measures and the belief of condom efficacyin the prevention of STD/HIV, whereas the factor as-sociated with actually consistent condom use was preg-nancy-preventing measure in ICSWs. Factors associ-ated with no intention to use condoms were low income,low STD/HIV knowledge level and the frequency ofvisiting CSW. The latter factor was also associatedwith never using condoms in male STD clinicattendees. Conclusions: Consistent condom use during com-mercial sex contacts was low, especially in clients.Greater effort is needed in condom promotion programin order to raise the level of condom use in commer-cial sex contacts.展开更多

文摘Background:People working outdoors in the Map Ta Phut pollution control area of Thailand require comprehen-sive health monitoring.In the past,studies have been done on the health effects of pollutants.However,there are few studies on musculoskeletal disorders(MSDs),and Thailand is struggling to meet the Sustainable Development Goals.Methods:This cross-sectional study examines access to health services and factors affecting MSDs among outdoor pollution workers(OPWs).The sample group includes OPWs,including local fisherman,street vendors,public car drivers,and traffic police.We studied 50 people from each of these groups,for a total of 200 people.Data were analyzed with inferential statistics using Chi-square test,McNemar test,and Univariate logistic regression.Results:The OPWs reported experiencing significantly more total MSDs pain than they did in the past(P<0.05).Factors affecting current MSDs pain,including occupation and working days per week,were significant(P<0.05).The street vendor group and public car driver group had(odds ratio[OR]=2.253,95%confidence interval[CI]:1.101 to 5.019)and(OR=2.681,95%CI:1.191 to 6.032)times higher risks of MSDs pain,respectively.OPWs who work>5 days per week had a(OR=1.464,95%CI:1.093 to 2.704)times higher risk of MSDs pain.52.7%of OPWs with MSDs,pain(n=110)had received an annual health check-up.In the past year,50.9%had minor illnesses and 21.8%had severe illnesses.OPWs receiving free treatment and visiting health service stations for no cost comprised 77.3%and 51.8%,respectively.60.9%used their right to receive treatment with universal health insurance cards.Conclusions:The study indicates that occupational groups with MSDs pain problems should exercise this right,according to the worker protection law.Local health agencies should organize activities or create accessible media to promote preventive medicine services,as many OPWs believe that health services can only be accessed when illness occurs.
文摘BACKGROUND Monkeypox(Mpox),is a disease of global public health concern,as it does not affect only countries in western and central Africa.AIM To assess Burundi healthcare workers(HCWs)s’level of knowledge and confidence in the diagnosis and management of Mpox.METHODS We conducted a cross-sectional study via an online survey designed mainly from the World Health Organization course distributed among Burundi HCWs from June-July 2023.The questionnaire comprises 8 socioprofessional-related questions,22 questions about Mpox disease knowledge,and 3 questions to assess confidence in Mpox diagnosis and management.The data were analyzed via SPSS software version 25.0.A P value<0.05 was considered to indicate statistical significance.RESULTS The study sample comprised 471 HCWs who were mainly medical doctors(63.9%)and nurses(30.1%).None of the 22 questions concerning Mpox knowledge had at least 50%correct responses.A very low number of HCWs(17.4%)knew that Mpox has a vaccine.The confidence level to diagnose(21.20%),treat(18.00%)or prevent(23.30%)Mpox was low among HCWs.The confidence level in the diagnosis of Mpox was associated with the HCWs’age(P value=0.009),sex(P value<0.001),work experience(P value=0.002),and residence(P value<0.001).The confidence level to treat Mpox was significantly associated with the HCWs’age(P value=0.050),sex(P value<0.001),education(P value=0.033)and occupation(P value=0.005).The confidence level to prevent Mpox was associated with the HCWs’education(P value<0.001),work experience(P value=0.002),residence(P value<0.001)and type of work institution(P value=0.003).CONCLUSION This study revealed that HCWs have the lowest level of knowledge regarding Mpox and a lack of confidence in the ability to diagnose,treat or prevent it.There is an urgent need to organize continuing medical education programs on Mpox epidemiology and preparedness for Burundi HCWs.We encourage future researchers to assess potential hesitancy toward Mpox vaccination and its associated factors.
文摘Background: Obesity is a chronic complex disease defined by excessive fat deposits that can impair health. Obesity occurs as a result of an imbalance in diet (energy intake) and physical activity (energy expended), multifactorial diseases due to obesogenic environment (availability of convenience food, media influence, etc.), psycho-social factors (social support systems, cultural/environmental influence, etc.) and genetic variants. Other causes are a subgroup of etiological factors (medications, diseases, immobilization, iatrogenic procedures, monogenic disease/genetic syndrome). Obesity is measured clinically by several common tools apart from body mass index (BMI), such as waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio, and neck circumference. WC and WHR are common tools for measuring central obesity while BMI measures generalized obesity. Aims: The goal of this study is to assess the prevalence of obesity amongst health workers of David Umahi Federal University Teaching Hospital, Uburu, Ebonyi state, Southeast Nigeria and to note the prevailing factors. A reliable estimate of the prevalence of obesity among health workers will contribute to the statistics needed to sway policymakers in the country to take urgent and substantial action on the increasing prevalence of obesity, especially in the healthcare industry. Methodology: The study was carried out between May 2024 and June 2024 at the David Umahi Federal University Teaching Hospital situated in Uburu, Ohaozara Local government area of Ebonyi state, Southeast Nigeria. The questionnaire was designed using the Finnish diabetic risk score (FINDRISC). It contained basic comprehending questions on age, gender, exposure to high blood pressure medication, and anthropometric measurement amongst others. Weight was taken with a portable weighing scale and height, with a stadiometer. Both were taken with shoes and headgear removed. The BMI was calculated using the weight (kg) divided by the square of the height (m2). Result: Generally, the prevalence of obesity (>30 kg/m2) in this study was low 17.6% (38), Overweight (BMI 25 - 30), 38.9%, (84) healthy Weight, (BMI 18.5 - 24.9), 43.5% (94). The study revealed that a family history of diabetes was significantly related to higher BMI, with participants more likely to be overweight or obese (p = 0.00030). Similarly, participants with a personal history of diabetes were predominantly in the obese category (p = 0.00038). Waist circumference also showed a strong association with BMI, as larger waist measurements were more common among obese individuals (p = 9.2 × 10−8). In contrast, the analysis found no significant relationships between BMI and age, gender, high blood pressure, or exercise habits. Conclusion: The socio-demographic determinants of obesity in this study were gender, age < 45 years and exposure to exercise. These determinants should form the areas of focus for interventions such as health education and the design of work environments as environments designed to promote physical activities while working will reduce the prevalence of obesity in tertiary institutions.
文摘Objectives: To propose the improvements measures by analysing the influencing factors of hand hygiene (HH) compliance by observing the behaviour of health care workers (HCWs). Method: The observational study was conducted at a public tertiary hospital in Zhejiang, China, from September 2018 to March 2021. A total of 58 HH observers were trained to conduct a direct observation on the HH behaviors of personnel in the hospital amongst the health care workers. We have observed over 9000 hand hygiene opportunities. The collected data were classified according to time factors, department parameters, and profession conduct of the observed. Hand hygiene (HH) compliance rates were calculated for each category, and a chi-square test was used to analyze differences of the HH compliance rates. Furthermore, binary logistic regression was used for multivariate analysis in each of the hand hygiene moments. Results: The HH compliance rates of HCWs were statistically different before and after the Corona Virus Disease 2019 (COVID-19) pandemic, in the morning and the afternoon, this was observed per parameters stated into objectives on weekdays vs non weekdays. And we found that HH compliance rates drop off a cliff from weekdays to non-weekdays. Conclusions: COVID-19, departments, professions, and weekdays were all factors that influence HH compliance amongst HCWs. However, the influencing factors were not all present in every HH behavior, and had different intensities of influence on HH compliance amongst the HCWs. These findings provide some reference for us to propose improvement measures.
文摘BACKGROUND Burnout syndrome is a significant issue among healthcare professionals worldwide,marked by depersonalization,emotional exhaustion,and a reduced sense of personal achievement.This psychological and physical burden profoundly affects healthcare professionals'quality of care and overall well-being.In Somalia,where the healthcare system faces numerous challenges,the escalating demand for medical services and inadequate resources,coupled with overwhelming workloads,long hours,and high-stress levels,make healthcare providers particularly vulnerable to burnout syndrome.This,in turn,affects both the mental health of healthcare personnel and the quality of care they provide.AIM To examine the prevalence and determinants of burnout syndrome among healthcare practitioners in Mogadishu,Somalia.METHODS This cross-sectional prospective study was performed among 246 healthcare providers employed at a tertiary care hospital in Mogadishu,Somalia,who were recruited via random sampling.Data were collected using questionnaires that covered sociodemographic,psychological,work-related characteristics,and burnout syndrome.Bivariate and multivariate logistic regression analyses were performed to identify the variables that correlated with burnout syndrome.The results were presented using adjusted odds ratios(AORs),95%CIs,and P values,with a cutoff of 0.05 for identifying significant associations.RESULTS Among the participants,24%(95%CI:18.8%–29.8%)exhibited symptoms of burnout syndrome.Factors associated with burnout included female gender(AOR=6.60;95%CI:2.29-19.04),being married(AOR=3.07;95%CI:1.14-8.28),being divorced or widowed(AOR=5.84;95%CI:1.35-25.35),working more than 7 night shifts(AOR=3.19;95%CI:1.30–7.82),having less than 5 years of job experience(AOR=5.28;95%CI:1.29-21.65),experiencing poor sleep quality(AOR=5.29;95%CI:1.88-14.89),and exhibiting depressive(AOR=4.46;95%CI:1.59-12.53)and anxiety symptoms(AOR=7.34;95%CI:2.49-21.60).CONCLUSION This study found that nearly one in four healthcare professionals suffers from burnout syndrome.Improving sleep quality,monitoring,and providing mental health support could enhance their well-being and patient care.
文摘Objectives:At the time of the bombing of the federal building in Oklahoma City,Oklahoma(OKC),it was the deadliest terrorist attack in the United States of America.Available research on this incident,and in general,has been quantitative,using deductive methods.The purpose of the current study was to systematically examine professional disaster response workers’emotions elicited spontaneously and in detail as they were experienced over time after a major disaster.This qualitative study will add to existing knowledge of psychopathology and the psychosocial effects of disasters on professional responders,which have not been explored by prior quantitative studies.Methods:A volunteer sample of 181 rescue and recovery workers for the 1995 bombing of the OKC Murrah Federal Building was interviewed approximately 3 years after the bombing.These responders were asked open-ended questions to elicit undirected responses in their own words.In these interviews,they were prompted to describe their feelings at 3 distinct time points:upon their arrival at the bombing scene(“immediately”),in the first 1 week following the bombing,and currently at the time of the interview(“now”).Results:Data items were coded into the 5 themes:Anticipation,Shock and awe,Negative reactions,Positive reactions,and Emotionally unengaged/unaffected.The emotional themes of the responders mapped into 2 conceptual domains.The first domain is related to common human responses to horrible events such as the bombing.The second domain is related to the professional identities of the disaster responders.Conclusions:Specific aspects of the professional responder roles asserted themselves,shaping their emotional responses distinctly from those of the bomb blast survivors.This study identified both negative and positive emotions,which may help identify risk for or resistance to posttraumatic stress disorder(PTSD).

文摘The research selected 13 factors from individual and family characters, construction site characters and work characters and analyzed the influences on the willingness of purchasing houses on construction sites with Logistic regression mod- el. The results showed that gender, age differences, personality, willingness on fami- ly land conversion, management of enterprises on construction sites, relatives and friends on construction lands, and Job satisfaction were approved by significant testing, but marital status, annual household income, the rate of migrant worker in a household, transportation in work city, and corporate reputation were not approved by significant testing.
文摘Objective: To understand the HIV/AIDS-related knowledge, attitudes and behaviors (KAB) among immigrant female factory workers(IFFW). Methods: A cross-sectional study was conducted among IFFWs sampled from several joint- venture and private factories in Dongguan city. Results: Out of 175 sampled workers, 165 qualified for inclusion and the median age was 22. The results showed that the IFFWs had low levels of knowledge about HIV/AIDS, and held many misconceptions. Thirty three of 76 (43.4%) unmarried IFFWs had premarital sexual contact, and more than half of these contacts were one-night stands (54.5%) . More than one quarter of the women(25.9%) never used condoms, 49.4% sometimes used condoms and 24.7% used condoms every time. Twenty-eight women (31.8%) had an induced abortion because of an unexpected pregnancy. Fourteen (14.9%) had been infected with STDs, and four IFFWs(2.8%)had tried drugs before the interview. Conclusion: In order to empower the IFFWs in the city to protect themselves from HIV, and to contain the rapid spread of HIV in our province, targeted HIV/ AIDS health promotion programs should be urgently implemented among IFFWs in Dongguan city. The programs should be designed to improve the knowledge of HIV, to promote condom use, and to reduce risky behaviors.

文摘In the context of the continuous development of the Internet,crowdsourcing has received continuous attention as a new cooperation model based on the relationship between enterprises,the public and society.Among them,a reasonably designed recommendation algorithm can recommend a batch of suitable workers for crowdsourcing tasks to improve the final task completion quality.Therefore,this paper proposes a crowdsourcing recommendation framework based on workers’influence(CRBI).This crowdsourcing framework completes the entire process design from task distribution,worker recommendation,and result return through processes such as worker behavior analysis,task characteristics construction,and cost optimization.In this paper,a calculation model of workers’influence characteristics based on the ablation method is designed to evaluate the comprehensive performance of workers.At the same time,the CRBI framework combines the traditional open-call task selection mode,builds a new task characteristics model by sensing the influence of the requesting worker and its task performance.In the end,accurate worker recommendation and task cost optimization are carried out by calculating model familiarity.In addition,for recommending workers to submit task answers,this paper also proposes an aggregation algorithm based on weighted influence to ensure the accuracy of task results.This paper conducts simulation experiments on some public datasets of AMT,and the experimental results show that the CRBI framework proposed in this paper has a high comprehensive performance.Moreover,CRBI has better usability,more in line with commercial needs,and can well reflect the wisdom of group intelligence.

文摘[Objective] This study aimed to clarify the correlation between changes of Apis mel ifera and the nectar secretion characteristics of nectariferous plants. [Method] Considering the nectar secretion characteristics of major and auxiliary nec-tariferous plants, six Apis mel ifera colonies were selected for measure the number of eggs, larvae, pupae and adult bees from Jan. to Dec. in 2012; based on that, their annual change curves were also plotted. [Result] The results showed that there were three peaks of the total number of A. mel ifera workers throughout the year：the first occurred on May 15th, with bees developed into an ideal population for col-lecting pomegranate nectar, and the second and third peaks occurred on July 15th and Oct. 15th, respectively, with bees developed into an ideal population for col ect-ing E. ciliate （Thuab） Hyland. [Conclusion] Prevention of Varroa jacobsoni should be carried out with two or more types of acaricides at the late nectar flow stages of the two nectariferous plants（pomegranate and E. ciliate （Thuab） Hyland） when there was a nectar deficiency. Prevention of Tropilaelaps clareae should be timely per-formed with sublimed sulfur in conjunction with acaricides. This study provides a theoretical basis for the high-quality and high-yielding production of honey, as wel as for the product safety.
文摘The unique two-stage "Chinese path" of China’s ru-ral-urban migration, which cannot be fully explained by classical theories of economic development, makes us to give peasant workers’ transformation to urban residents a top priority. On the basis of fully explaining peasant workers’ transformation to urban residents, a method for measuring its process has been advanced and then confirmed with the data of March in 2005 from surveys to peasant workers in Wuhan. Finally, the suggestions of acceler-ating peasant workers’ transformation to urban residents to pro-mote the construction of a harmonious society have been drawn from the analysis.
文摘Background: Commercial sex workers and clientsare important core populations in the transmission ofsexually transmitted diseases (STDs) and human im-munodeficiency virus (HIV) infection. Research on thefrequency and determinants of condom use in com-mercial sex workers and their clients is important inincreasing condom use and reduction of the STD/HIV.Burden. Objectives: To establish the frequency of and fac-tors related to intention to use condoms and actualcondom use in commercial sex contacts and to deter-mine the differences in condom use between sex work-ers and clients.Methods: Incarcerated commercial sex workers(ICSW) and male STD clinic attendees were recruitedinto a cross-sectional study to obtain data on the fre-quency and factors associated with intention to usecondoms and condom use in commercial sexual con-tacts with an interviewer-administered questionnaire.Consistent condom use in ICSWs and never usingcondoms in male STD clinic attendees were analyzedusing univariate and multivariate logistic regressionmodels. Results: The frequency of reported consistent in-tention to use condoms and reported actual condomuse was 62% and 50.6%, respectively among 158ICSWs. For male STD clinic attendees, the propor-tion of reported consistent intention to use condomsand reported actual condom use was 10% and 20.7%,respectively. The factors positively influencing theconsistent intention to use condoms were pregnancypreventing measures and the belief of condom efficacyin the prevention of STD/HIV, whereas the factor as-sociated with actually consistent condom use was preg-nancy-preventing measure in ICSWs. Factors associ-ated with no intention to use condoms were low income,low STD/HIV knowledge level and the frequency ofvisiting CSW. The latter factor was also associatedwith never using condoms in male STD clinicattendees. Conclusions: Consistent condom use during com-mercial sex contacts was low, especially in clients.Greater effort is needed in condom promotion programin order to raise the level of condom use in commer-cial sex contacts.
