This is probably a result of increase in the sedentary life style and the increasing shift to western diet. Obesity in children and adolescents has adverse consequences. These include increase in the rate of Diabetes Mellitus, hypertension, dyslipidemia, cardiovascular diseases, etc with resultant increase in premature deaths. Objectives: To determine the socio-demographic and behavioral factors associated with overweight and obesity in apparently healthy secondary school adolescents. Methods: This was a cross-sectional study of secondary school adolescents aged 10 - 19 years randomly selected from two public schools and three private schools. The weight and heights of study subjects were measured using standard equipment. Body mass index (BMI) was appropriately calculated and the WHO growth reference standard for age and gender, specific percentile for BMI was used to define overweight 85<sup>th</sup> to 97<sup>th</sup> and obese (97<sup>th</sup> percentile and above). Results: Data were initially collected from 1250 participants, but 52 were excluded due to improperly completed questionnaires. Thus, a total of 1198 students were ultimately included in the study, giving a response rate of 95.8%. These included 621 females (51.8%) and 577 males (48.2%) aged 10 - 19 years giving a F:M ratio of 1:0.9. The mean age of the students was 15.07 ± 1.96 years overall, 15.13 ± 2.08 years for males and 15.03 ± 1.83 years for females. There was no statistically significant difference between male and female in the distribution of age groups (p = 0.12). The mean BMI was 21.51 ± 3.57 kg/m<sup>2</sup> for females and 20.22 ± 3.16 kg/m<sup>2</sup> for males. The BMI was significantly higher in females in all age groups (p < 0.001) except those aged 10 - p = 0.13). The prevalence rates of overweight and obesity were higher in females than males (17.7% vs 10.7%, 5.6% vs 4.5% respectively;p ≤ 12 yrs;p = 0.04). The frequent consumption of sugar based beverages (p p p = 0.03) were significantly associated with both overweight and obesity (p p p < 0.001) were also significantly associated with obesity. Conclusion: Sociodemographic factors such as gender, socioeconomic status and behavioral patterns were major contributors to obesity. Behavioral interventions including regulating the intake of sugar based beverages and reducing the time spent on sedentary activities could be useful strategies in reducing the high prevalence of overweight and obesity among adolescents.展开更多

The aim of this study is to investigate the key biomedical and lifestyle factors for the development of type 2 diabetes as well as the cardiovascular diabetes complications in the population aged 25-64 from Kardzhali region, Bulgaria. The results of the study show the existence of behavioral and biological risk factors of health, as well as family history in the studied individuals who suffer from diabetes. The connection between diabetes and certain cardiovascular diseases such as ischemic heart disease, myocardial infarction and cardiovascular disease is confirmed. This requires the development and implementation of intervention activities among the population of Kardzhali, aimed at reducing the level of diabetes risk factors, early identification of risk groups and timely treatment of the diseased.展开更多

The first group of structures is composed of buildings that implement three common design practices; namely, fully infilled, weak ground story and short columns. The three design practices are applied during the design process of a reinforced concrete building. The structures of the second group vary according to the value of the behavioral factors used to define the seismic forces as specified in design procedures. Most seismic design codes belong to the class of prescriptive procedures where if certain constraints are fulfilled, the structure is considered safe. Prescriptive design procedures express the ability of the structure to absorb energy through inelastic deformation using the behavior factor. The basic objective of this work is to assess both groups of structures with reference to the limit-state probability of exceedance. Thus, four limit state fragility curves are developed on the basis of nonlinear static analysis for both groups of structures. Moreover, the 95% confidence intervals of the fragility curves are also calculated, taking into account two types of random variables that influence structural capacity and seismic demand.展开更多

The mechanism underlying RBD is unclear. Several prospective studies have reported that specific non-motor symptoms predict a conversion risk of developing a neurodegenerative disease, including olfactory dysfunction, abnormal color vision, autonomic dysfunction, excessive daytime sleepiness, depression, and cognitive impairment. Parkinson＇s disease （PD） with RBD exhibits clinical heterogeneity with respect to motor and non-motor symptoms compared with PD without RBD. In this review, we describe the main clinical and pathogenic features of RBD, focusing on its association with other non-motor symptoms of parkinsonism.展开更多

The method is composed of three departs: human behavior decomposition, human behavior case representation and case-based reasoning. The new approach was proposed to decompose behavior into sub-behaviors that are easier to recognize using a saliency-based visual attention model. New representation of behavior was introduced, in which the sub-behavior and the associated time characteristic of sub-behavior were used to represent behavior case. In the process of case-based reasoning, apart from considering the similarity of basic sub-behaviors,order factor was proposed to measure the similarity of a time order among the sub-behaviors and span factor was used to measure the similarity of duration time of each sub-behavior, which makes the similarity calculations more rational and comprehensive.Experimental results show the effectiveness of the proposed method in comparison with other related works and can run in real-time for the recognition of suspicious behaviors.展开更多

Nevertheless, many important developments are still needed in order to define more reliable and effective assessment procedures. Moreover, regarding existing buildings, it should be highlighted that due to the low knowledge level, the linear elastic analysis is the only analysis method allowed. The same codes（such as NTC2008, EC8） consider the linear dynamic analysis with behavior factor as the reference method for the evaluation of seismic demand. This type of analysis is based on a linear-elastic structural model subject to a design spectrum, obtained by reducing the elastic spectrum through a behavior factor. The behavior factor（reduction factor or q factor in some codes） is used to reduce the elastic spectrum ordinate or the forces obtained from a linear analysis in order to take into account the non-linear structural capacities. The behavior factors should be defined based on several parameters that influence the seismic nonlinear capacity, such as mechanical materials characteristics, structural system, irregularity and design procedures. In practical applications, there is still an evident lack of detailed rules and accurate behavior factor values adequate for existing buildings. In this work, some investigations of the seismic capacity of the main existing RC-MRF building types have been carried out. In order to make a correct evaluation of the seismic force demand, actual behavior factor values coherent with force based seismic safety assessment procedure have been proposed and compared with the values reported in the Italian seismic code, NTC08.展开更多

Bayesian estimation is usually used to construct statistical intervals, however, its computational intensity is a big challenge for large complex surveys. Frequentist approaches, such as bootstrapping, and Monte Carlo (MC) simulation, are also applied but not evaluated in terms of the interval magnitude, width, and the computational time consumed. The 2013 Florida Behavioral Risk Factor Surveillance System data was used as a case study. County-level estimated prevalence of three health-related outcomes was obtained through a GLMM;and their 95% confidence intervals (CIs) were generated from bootstrapping and MC simulation. The intervals were compared to 95% credential intervals through a hierarchial Bayesian model. The results showed that 95% CIs for county-level estimates of each outcome by using MC simulation were similar to the 95% credible intervals generated by Bayesian estimation and were the most computationally efficient. It could be a viable option for constructing statistical intervals for small area estimation in public health practice.展开更多

文摘Non-communicable diseases(NCDs)account for over 70%of all deaths worldwide each year,primarily encompassing cardiovascular diseases(CVD),cancers,diabetes,and chronic respiratory diseases[1].Unlike infectious diseases,NCDs are closely associated with modifiable behavioral risk factors,including tobacco,high alcohol consumption,unhealthy diets,and insufficient physical activity[2,3].These behavioral risk factors are prevalent globally and exert long-term adverse effects on health,serving as primary drivers of the high prevalence and mortality rates of NCDs[4].Research indicates that over 50%of deaths related to NCDs are preventable,underscoring the significant public health value of implementing behavioral interventions aimed at preventing and controlling these diseases[5].
文摘Objective:This study aimed to examine the influence of behavioral lifestyle factors on recent episodic memory retention capacity among young-old adults(aged 60-69 years)in China.The findings provide scientific evidence to inform proactive strategies to mitigate cognitive decline risk within China’s rapidly aging population.Methods:Utilizing data from the 2022 wave of the China Family Panel Studies(CFPS),a total of 2,772 adults aged 60-69 were included in the analytical sample.Recent episodic memory retention capacity(scored 0-5 points,based on self-reported assessment)served as the dependent variable.Six categories of behavioral lifestyle indicators(including exercise frequency,sleep quality,dietary patterns,etc.)were analyzed as independent variables.Associations were assessed using multivariate ordinal logistic regression models,controlling for relevant covariates.Results:Self-reported potential impairment in recent episodic memory was identified by 47.19%of respondents.Multivariate analysis revealed significant associations between behavioral lifestyle factors and memory retention capacity.Regular exercise(OR=1.297,95%CI:1.118-1.504),meat consumption(OR=1.765,95%CI:1.393-2.237),regular reading habits(OR=1.599,95%CI:1.283-1.992),and internet use(OR=1.413,95%CI:1.217-1.641)emerged as significant protective factors.Abnormal sleep duration was detrimentally associated with retention capacity(too short:OR=0.728,95%CI:0.591-0.897;too long:OR=0.810,95%CI:0.670-0.980).Significant associations were also observed for control variables:urban residence(OR=1.270,95%CI:1.100-1.467),high school education or above(OR=1.543,95%CI:1.293-1.841),and better self-rated health status(OR=1.156,95%CI:1.089-1.227)were positively correlated with better memory retention.Conclusions:Optimal sleep duration,regular physical exercise,meat intake,habitual reading,and internet engagement positively predict self-assessed recent episodic memory retention capacity in Chinese young-old adults.These findings underscore the potential for multi-faceted lifestyle interventions to enhance cog-nitive health in aging populations.Specifically,strategies should encompass community-based sleep hygiene management,tailored nutritional interventions(especially promoting adequate protein sources like meat),enhanced digital literacy and internet accessibility programs,and the promotion of age-appropriate physical activity initiatives.Furthermore,implementing culturally responsive strategies adapted to urban-rural contexts-such as deploying“mobile cognitive health units”in rural areas and fostering digital reading platforms in urban settings-is recommended to optimize intervention effectiveness.

文摘Eye position varies significantly among taxonomic levels,and this variation is often shaped by ecological and behavioral factors.Eye position is often positively associated with interorbital distance where species with broad visualfields possess a large distance between the left and right eye.Selective pressures underlying the evolution of the eye position are especially studied in birds and mammals.However,selective pressures underlying the evo-lution of anuran eye position which can be indicated by interorbital distance keep unknown.Here,we investigated the effects of ecological(e.g.habitat type,light availability)and behavioral factors(e.g.activity pattern,foraging mobility,and defensive strategy)on variations in interorbital distance among 260 anuran species in China.Our results showed that variations of the interorbital distance can be significantly predicted by the activity pattern.Noc-turnal species had larger interorbital distance than both nocturnal and diurnal species.We also found that foraging mobility and defensive strategy markedly affected variation of interorbital distance.Species having slower foraging mobility and possessing poison glands had larger interorbital distance than species having faster foraging mobility and possessing non-position glands.Light availability tended to be associated with variation of interorbital distance,indicating that species living in weak light tended to possess larger interorbital distance.However,variations of the interorbital space were not associated with habitat type in anurans.Ourfindings suggest that anuran behaviors play key roles in shaping visualfields and eye position,thus affecting the evolution of interorbital distance.

文摘With nearly three-quarters of global deaths attributed to lifestyle-associated di-seases,effective lifestyle modifications are more urgent than ever.The American Heart Association’s framework for cardiovascular health has evolved signifi-cantly,transitioning from'Life’s Simple 7'to'Life’s Essential 8'with the incorpo-ration of sleep,and further to'Life’s Essential 9'by adding mental health as a key component.Despite these advancements,recent evidence reveals a persistently low prevalence of ideal cardiovascular and cerebrovascular health behaviors across populations.These findings highlight the critical gap in addressing modi-fiable lifestyle and psychosocial factors.To reduce the global disease burden,public health strategies must prioritize comprehensive interventions that encom-pass physical,neurological,and mental well-being.
文摘Background: The prevalence of obesity among adolescent has been on the increase worldwide. This is probably a result of increase in the sedentary life style and the increasing shift to western diet. Obesity in children and adolescents has adverse consequences. These include increase in the rate of Diabetes Mellitus, hypertension, dyslipidemia, cardiovascular diseases, etc with resultant increase in premature deaths. Objectives: To determine the socio-demographic and behavioral factors associated with overweight and obesity in apparently healthy secondary school adolescents. Methods: This was a cross-sectional study of secondary school adolescents aged 10 - 19 years randomly selected from two public schools and three private schools. The weight and heights of study subjects were measured using standard equipment. Body mass index (BMI) was appropriately calculated and the WHO growth reference standard for age and gender, specific percentile for BMI was used to define overweight 85<sup>th</sup> to 97<sup>th</sup> and obese (97<sup>th</sup> percentile and above). Results: Data were initially collected from 1250 participants, but 52 were excluded due to improperly completed questionnaires. Thus, a total of 1198 students were ultimately included in the study, giving a response rate of 95.8%. These included 621 females (51.8%) and 577 males (48.2%) aged 10 - 19 years giving a F:M ratio of 1:0.9. The mean age of the students was 15.07 ± 1.96 years overall, 15.13 ± 2.08 years for males and 15.03 ± 1.83 years for females. There was no statistically significant difference between male and female in the distribution of age groups (p = 0.12). The mean BMI was 21.51 ± 3.57 kg/m<sup>2</sup> for females and 20.22 ± 3.16 kg/m<sup>2</sup> for males. The BMI was significantly higher in females in all age groups (p < 0.001) except those aged 10 - p = 0.13). The prevalence rates of overweight and obesity were higher in females than males (17.7% vs 10.7%, 5.6% vs 4.5% respectively;p ≤ 12 yrs;p = 0.04). The frequent consumption of sugar based beverages (p p p = 0.03) were significantly associated with both overweight and obesity (p p p < 0.001) were also significantly associated with obesity. Conclusion: Sociodemographic factors such as gender, socioeconomic status and behavioral patterns were major contributors to obesity. Behavioral interventions including regulating the intake of sugar based beverages and reducing the time spent on sedentary activities could be useful strategies in reducing the high prevalence of overweight and obesity among adolescents.

文摘BACKGROUND The American Heart Association defines cardiovascular health in terms of four behaviors(smoking,diet,physical activity,and body weight)and three factors(plasma glucose,cholesterol,and blood pressure).By this definition,the preva-lence of ideal cardiovascular health behaviors and factors(ICHBF)is negatively correlated with all-cause mortality and risks of cardiovascular and cerebrovas-cular diseases and malignancy.AIM To investigate the changing trends of cardiovascular and cerebrovascular health scores in the Kailuan study population from 2006 to 2011.METHODS The Kailuan population data from three health checkups held in 2006-2007,2008-2009,and 2010-2011 were analyzed,and the constituent ratios of cardiovascular and cerebrovascular health behaviors and factors at ideal,intermediate,and poor levels were calculated by using Huffman and Capewell method.Simultaneously,the cardiovascular and cerebrovascular health behavior and factor scores were calculated.RESULTS From 2006 to 2007,the proportion of people with ideal physical exercise,low salt diet,ideal body mass index,ideal total cholesterol level,no smoking,ideal blood sugar,and ideal blood pressure was 13.12%,9.34%,49.17%,64.20%,49.27%,69.99%,and 20.55%,respectively,in men with a health score of 8.46,and 12.00%,9.13%,61.60%,64.28%,98.19%,78.90%and 36.92%in women,with a score of 10.02.From 2008 to 2009,the proportion was 16.09%,14.04%,51.94%,65.02%,40.18%,66.44%,and 17.04%in men,with a score of 8.18,and 16.860%,17.360%,64.010%,67.433%,98.220%,76.370%,and 42.340%in women,with a score of 10.12.From 2010 to 2011,the proportion was 12.22%,17.65%,49.40%,68.33%,48.17%,64.67%,and 14.68%in males,having a score of 8.21,while in females,the proportion was 11.83%,18.09%,49.40%,67.85%,98.82%,74.52%,and 37.78%,with a score of 9.90.Core Tip:The American Heart Association defines ideal cardiovascular health as the concurrent presence of ideal health parameters(blood glucose,total cholesterol,and blood pressure levels)and ideal health behaviors(weight status,diet,physical activity,and smoking).Our study design was retrospective and based on the Kailuan study.This prospective study was initiated in July 2006 to evaluate the risk factors and interventions for cardiovascular diseases and cerebrovascular diseases in the Kailuan community population,with several articles having been published on such chronic non-communicable diseases.A fixed population was constituted from these 57659 participants,and their cerebrovascular and cardiovascular health parameters and behaviors were surveyed from 2006 to 2011.Furthermore,the distributions of cardiovascular health parameters and behaviors were portrayed,and their health scores were estimated.cholesterol level,no smoking,ideal blood sugar,and ideal blood pressure was 16.09%,14.04%,51.94%,65.02%,40.18%,66.44%,and 17.04%,and it was 16.86%,17.36%,64.01%,67.433%,98.22%,76.37%,and 42.34%for women.From 2010-2011,the proportion of men with ideal physical exercise,low salt diet,ideal body mass index,and ideal total cholesterol level,no smoking,ideal blood sugar,and ideal blood pressure was 12.22%,17.65%,49.40%,68.33%,48.17%,64.67%,and 14.68%,and it was 11.83%,18.09%,49.40%,67.85%,98.82%,74.52%,and 37.78%in women.The prevalence of ideal cardiovascular and cerebrovascular health behaviors and factors of different genders from 2006 to 2011 is shown in Table 1 and Table 2.The prevalence of poor and intermediate cardiovascular and cerebrovascular health behaviors and factors of different genders from 2006 to 2011 was described in our previous research[11].The health scores of men and women in 2006,2008,and 2010 were 8.46 and 10.02,8.18 and 10.12,as well as 8.21 and 9.90,respectively;the distribution of cardiovascular and cerebrovascular health behaviors and factor scores of different genders from 2006 to 2011 are shown in Table 3 and Table 4.The mean±SD of body mass index,blood pressure,fasting blood glucose,and total cholesterol levels of different genders from 2006 to 2011 are shown in Table 5 and Table 6.

文摘This paper presents a new FRP retrofi tting scheme to strengthen local beam-column joints in reinforced concrete(RC) frames.The new retrofi tting scheme was proposed following a preliminary study of four different existing retrofi tting schemes.A numerical simulation was conducted to evaluate the effectiveness of FRP-strengthened reinforced concrete frames by bridging behavior of local joints to the whole structure.Local confi nement effects due to varying retrofi tting schemes in the joints were simulated in the frame model.The seismic behavior factor was used to evaluate the seismic performance of the strengthened RC frames.The results demonstrated that the new proposed retrofi tting scheme was robust and promising,and fi nite element analysis appropriately captured the strength and global ductility of the frame due to upgrading of the local joints.
文摘In this work, fragility analysis is performed to assess two groups of reinforced concrete structures. The first group of structures is composed of buildings that implement three common design practices; namely, fully infilled, weak ground story and short columns. The three design practices are applied during the design process of a reinforced concrete building. The structures of the second group vary according to the value of the behavioral factors used to define the seismic forces as specified in design procedures. Most seismic design codes belong to the class of prescriptive procedures where if certain constraints are fulfilled, the structure is considered safe. Prescriptive design procedures express the ability of the structure to absorb energy through inelastic deformation using the behavior factor. The basic objective of this work is to assess both groups of structures with reference to the limit-state probability of exceedance. Thus, four limit state fragility curves are developed on the basis of nonlinear static analysis for both groups of structures. Moreover, the 95% confidence intervals of the fragility curves are also calculated, taking into account two types of random variables that influence structural capacity and seismic demand.

文摘Rapid eye movement sleep behavior disorder （RBD） is one of the most common non-motor symptoms of parkinsonism, and it may serve as a prodromal marker of neurodegenerative disease. The mechanism underlying RBD is unclear. Several prospective studies have reported that specific non-motor symptoms predict a conversion risk of developing a neurodegenerative disease, including olfactory dysfunction, abnormal color vision, autonomic dysfunction, excessive daytime sleepiness, depression, and cognitive impairment. Parkinson＇s disease （PD） with RBD exhibits clinical heterogeneity with respect to motor and non-motor symptoms compared with PD without RBD. In this review, we describe the main clinical and pathogenic features of RBD, focusing on its association with other non-motor symptoms of parkinsonism.

文摘A novel method case-based reasoning was proposed for suspicious behavior recognition. The method is composed of three departs: human behavior decomposition, human behavior case representation and case-based reasoning. The new approach was proposed to decompose behavior into sub-behaviors that are easier to recognize using a saliency-based visual attention model. New representation of behavior was introduced, in which the sub-behavior and the associated time characteristic of sub-behavior were used to represent behavior case. In the process of case-based reasoning, apart from considering the similarity of basic sub-behaviors,order factor was proposed to measure the similarity of a time order among the sub-behaviors and span factor was used to measure the similarity of duration time of each sub-behavior, which makes the similarity calculations more rational and comprehensive.Experimental results show the effectiveness of the proposed method in comparison with other related works and can run in real-time for the recognition of suspicious behaviors.
文摘In recent years, several research groups have studied a new generation of analysis methods for seismic response assessment of existing buildings. Nevertheless, many important developments are still needed in order to define more reliable and effective assessment procedures. Moreover, regarding existing buildings, it should be highlighted that due to the low knowledge level, the linear elastic analysis is the only analysis method allowed. The same codes（such as NTC2008, EC8） consider the linear dynamic analysis with behavior factor as the reference method for the evaluation of seismic demand. This type of analysis is based on a linear-elastic structural model subject to a design spectrum, obtained by reducing the elastic spectrum through a behavior factor. The behavior factor（reduction factor or q factor in some codes） is used to reduce the elastic spectrum ordinate or the forces obtained from a linear analysis in order to take into account the non-linear structural capacities. The behavior factors should be defined based on several parameters that influence the seismic nonlinear capacity, such as mechanical materials characteristics, structural system, irregularity and design procedures. In practical applications, there is still an evident lack of detailed rules and accurate behavior factor values adequate for existing buildings. In this work, some investigations of the seismic capacity of the main existing RC-MRF building types have been carried out. In order to make a correct evaluation of the seismic force demand, actual behavior factor values coherent with force based seismic safety assessment procedure have been proposed and compared with the values reported in the Italian seismic code, NTC08.
文摘Generalized Linear Mixed Model (GLMM) has been widely used in small area estimation for health indicators. Bayesian estimation is usually used to construct statistical intervals, however, its computational intensity is a big challenge for large complex surveys. Frequentist approaches, such as bootstrapping, and Monte Carlo (MC) simulation, are also applied but not evaluated in terms of the interval magnitude, width, and the computational time consumed. The 2013 Florida Behavioral Risk Factor Surveillance System data was used as a case study. County-level estimated prevalence of three health-related outcomes was obtained through a GLMM;and their 95% confidence intervals (CIs) were generated from bootstrapping and MC simulation. The intervals were compared to 95% credential intervals through a hierarchial Bayesian model. The results showed that 95% CIs for county-level estimates of each outcome by using MC simulation were similar to the 95% credible intervals generated by Bayesian estimation and were the most computationally efficient. It could be a viable option for constructing statistical intervals for small area estimation in public health practice.
文摘Objective:Sedentary lifestyle is a major risk factor for physical and mental problems,such as cardiovascular,musculoskeletal diseases,and psychological stress.About 60% of the world’s population is not sufficiently physically active in leisure time or during work and social activities.This study aimed to determine the prevalence of inactive Jordanian adults and describe their demo-graphic and behavioral characteristics.Methods:The study used data from the behavioral risk factors surveillance survey conducted in Jordan in 2007.The sample size was 3654.Respondents who were physically inactive for more than 240 min daily(sleep time not included)were considered to have a sedentary lifestyle.Data were analyzed with the program SPSS.Results:The prevalence of a sedentary lifestyle was 82.8%(2965 respondents),with a mean sedentary time of 587 min(95%confidence interval 581-594 min).Among the physically inactive adults,52.6% were men,one third of them aged 35-44 years.Sedentary lifestyle was reported by 30% of those with a secondary level of education or above.Of those with a sedentary lifestyle,37.6% were housewives and 37.5% were employees;66% of them were overweight and obese.Of the physically inactive people,2.5%had a history of heart failure and 1.3%had a history of cer-ebrovascular accidents;57.2% of them tried to engage more in physical activity and almost three quarters of them were interested in improving their dietary habits.Conclusion:Most Jordanian adults have a sedentary lifestyle,which emphasizes that there is a public health problem.Many of them are attempting to lead a healthier lifestyle.Therefore,there is an urgent need to launch an applicable national plan that enables people to practice a healthier lifestyle.
