Introduction: Malaysia suffers from obesity problems with nearly a quarter of the children and adolescents being overweight or obese. Validated methods are needed to measure the trend of overweight and obesity easily.Objective: The study investigates the precision of Malaysian late adolescents' self-reported height and weight compared to direct-measured methods.Methods:   About 114 young adults aged 19-20 years old participated in this cross sectional study in 2019. Self-reported and direct-measured anthropometrics including height and weight were gathered through phone calls and study instruments. The obtained height and weight values calculates BMI and determines classifications.Results: The ICC value were excellent between reported and measured weight (ICC= 0.94; 95% CI=0.91-0.96), height (ICC= 0.95; 95% CI=0.83-0.98) and BMI (ICC = 0.89; 95% CI=0.78-0.94) were found. Additionally, good agreement observed from B & A plots indicated that the differences between both independent measurement variables were minor and most of the differences were within the area of the limit of agreement at the population level for their anthropometric measurements. The Cohen’s Kappa showed substantial agreement of BMI calculated from reported weight and height (ҡ = 0.61; 95% CI= 0.48-0.74), boys (ҡ = 0.67; 95% CI=0.43-0.91) and girls (ҡ = 0.58; 95% CI=0.43-0.73).Conclusion: This validation study concluded that self-reported height and weight were in agreement with direct-measured methods. This technique can be utilized to assess the anthropometric status of Malaysian late adolescents for population studies.

There is a significant increase in overweight and obesity in adolescents worldwide. Here, we performed a cross-sectional study to examine the potential association between food consumption profiles and overweight in a large number of adolescents from Brazil. Sampling by clusters and conglomerates was carried out in students of public schools in Salvador, Brazil, between June and December 2009 and 1496 adolescents were evaluated. Data on socio-epidemiological data, anthropometric status and food consumption were captured. Multivariate analyses, such as hierarchical clustering and correlation networks, were used to perform a detailed description of food consumption profiles. There were differences in age and anthropometric status related to sex. Four clusters of food groups were identified based on the intake profile in the study population. No disparities in food intake were observed in individuals stratified by sex or anthropometric status. Furthermore, network analysis revealed that overweight or obesity were hallmarked by a selectivity in the ingestion of food groups that resulted in the appearance of inverse correlations of consumption, which was not present in eutrophic adolescents. Thus, overweight and obesity are associated with preferential choices of ingestion of specific food groups, which result in the appearance of inverse correlations of consumption. Such knowledge may serve as basis for future targeted nutritional interventions in adolescents.

Abstract Objectives: This study aimed to examine age-specific trends in the prevalence of overweight and obesity in schoolchildren in Kuwait over a 13-year period (2007 to 2019) using the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC) and the International Obesity Taskforce (IOTF) definitions. Design: Using cross-sectional approach, Kuwait Nutrition Surveillance System (KNSS) objectively measured weight and height of schoolchildren over a 13-year period. Log-binomial regression models were used to examine age-specific trends of obesity and overweight over the study period. Setting: Public primary, middle, and high schools in all provinces of Kuwait. Participants: Schoolchildren aged 5-19 years (N 172 603) Results: According to the WHO definition, the prevalence of overweight and obesity in schoolchildren respectively increased from 17.73% and 21.37% in 2007 to 20.19% and 28.39% in 2019 (P for trends<0.001). There is evidence that the obesity in females (but not males) has levelled off in the period 2014-2019 according to the three definitions of obesity, which is corroborated by a similar trend in the mean of BMI-for-age Z score. Conclusion: The prevalence of obesity and overweight in schoolchildren in Kuwait has risen over the last 13 years and trends are similar across all definitions. Obesity is no longer increasing at the same pace and there is evidence that the prevalence of obesity in females has plateaued. The current level of childhood overweight and obesity is too high and requires community-based and school-based interventions.

Introduction: Proactive prediction of the epidemiologic dynamics of viral diseases and outbreaks of the likes of COVID-19 has remained a difficult pursuit for scientists, public health researchers, and policymakers. It is unclear whether RT-PCR Cycle Threshold (Ct) values of COVID-19 (or any other virus) as indicator of viral load, could represent a possible predictor for underlying epidemiological changes on a population level. Objectives: To investigate whether population-wide changes in SARS-CoV-2 RT-PCR Ct values over time are associated with the daily fraction of positive COVID-19 tests. In addition, this study analyses the factors that could influence the RT-PCR Ct values. Method: A retrospective cross-sectional study was conducted on 63,879 patients from May 4, 2020 to September 30, 2020, in all COVID-19 facilities in the Kingdom of Bahrain. Data collected included number of tests and newly diagnosed cases, as well as Ct values, age, gender nationality, and symptomatic status. Results: Ct values were found to be negatively and very weakly correlated with the fraction of daily positive cases in the population r = -0.06 (CI95%: -0.06; -0.05; p=0.001). The R-squared for the regression model (adjusting for age and number of daily tests) showed an accuracy of 45.3%. Ct Values showed an association with nationality (p=0.012). After the stratification, the association between Ct values and the fraction of daily positive cases was only maintained for the female gender and Bahraini-nationality. Symptomatic presentation was significantly associated with lower Ct values (higher viral loads). Ct values do not show any correlation with age (p=0.333) or gender (p=0.522). Conclusion: We report one of the first and largest studies to investigate the epidemiological associations of Ct values with COVID-19. Ct values offer a potentially simple and widely accessible tool to predict and model epidemiological dynamics on a population level. More population studies and predictive models from global cohorts are necessary.

Nutritional status of Medical College students is an indicator of health & wellbeing at both the individual & the population level. This cross sectional study was carried out to assess the overweight and obesity as well as underweight among the students of Khwaja Yunus Ali Medical College, Enayetpur, Sirajgonj. All the students aged 18 -23 years reading in KYAMC were included in this study. Body weight, height and waist-hip ratio were measured and their relative information was collected with a self- administered, predesigned and pretested questionnaire. A total of 239 students data were found correct. Body mass index (BMI) was computed and categorized it into normal, overweight and obese according to WHO (1997) classification and analyzed for age, sex, waist-hip ratio and BMI category for assessing the nutritional status. In this study,157 (65.7%) students [male:53.5% & female:46.5%] were found in normal group, 38 students (15.9%) were overweight [male:44.7% and female:55.3%] and 44 students (18.4%) were in underweight group [male:50% and female:50%]. On splitting the data, the prevalence of underweight in different age groups decreases as the age advances but no such trend is observed in the case of overweight group and the proportion of overweight among the female students were more than that of male [18.1& vs 13.8%]. Waist-hip ratio was categorized into normal and overweight category and the prevalence of overweight is higher in female students than the male [80.8% vs 19.2%]. The results indicate the presence of a dual burden, underweight as well as overweight among the Medical College students in our country. Additional nutritional education, regular physical exercise and outdoor game facilities are recommended to overcome the problems.KYAMC Journal Vol. 6, No.-1, Jul 2015, Page 579-582

Aims: To investigate the relationship between anthropometric status and quality of life in children with asthma.Methods: Case-control study, including students from third to eighth grade of elementary school at the city of Ijuí, Rio Grande do Sul, Brazil. The first phase of the study consisted of a cross-sectional study, when a questionnaire of screening was sent to the students' homes to be completed by the parents or guardians, aiming to identify children with asthma, which were allocated to the group of cases (positive responses to cough, wheezing without colds, use of any medication for asthma in the last 12 months and/or medical diagnosis of asthma). For the control group, students matched by sex and age whose responses were negative for asthma were selected, at the rate of two controls for each case. The children received home visits from trained researchers, who presented to the participants and their parents/guardians a questionnaire about health related quality of life. Evaluation of anthropometric status was carried out at the schools by the researchers.Results: In the first phase od the study 1,691 students were investigated, and 184 (10.8%) were classified as having asthma. Of these, 486 students responded to the questionnaire of quality of life: 122 with asthma and 364 controls. Anthropometric assessment was performed in 414 children (106 cases and 308 controls). Eutrophic children totaled 237 (57.2%), low weight 8 (1.9%), overweight 90 (21.7%) and obese 79 (19.1%). Overweight/obesity was observed in 49 (46.2%) students of the group with asthma and in 120 (38.9%) in the control group (p<0.001). When comparing the quality of life between the groups, lower scores were observed among the asthma group in the physical well-being domain (p<0.001) and in the total score of quality of life (p=0.003). In children with asthma plus overweight/obesity, the mean score on the physical well-being domain was lower when compared to the group without asthma and eutrophic (p=0.010).Conclusions: When comparing students between seven and 18 years with or without history of asthma, asthma was associated with poor quality of life. Considering overweight and obesity as comorbidities, quality of life was worse for this group of students in the physical well-being domain.

Breakfast Skipping

Abstract.Aim: To assess the association of breakfast skipping with overweight and obesity among children in Albania, a post-communist country in the Western Balkans, which is undergoing a long and difficult political and socioeconomic transition towards a market-oriented economy. Methods: A nationwide cross-sectional study was carried out in Albania in 2013 including a representative sample of 5810 children aged 7.0 – 9.9 years (49.5% girls aged 8.4 ± 0.6 years and 51.5% boys aged 8.5 ± 0.6 years; overall response rate: 97%). Children were measured for height and weight, and body mass index (BMI) calculated. Cut-off BMI values of the World Health Organization (WHO) and the International Obesity Task Force (IOTF) were used to define overweight and obesity in children. Demographic data were also collected. Results: Upon adjustment for age, sex, and place of residence, breakfast skipping was positively related to obesity (WHO criteria: OR = 1.5, 95% CI = 1.3–1.9; IOTF criteria: OR = 1.9, 95% CI = 1.4–2.5), but not overweight (OR = 1.1, 95% CI = 0.9–1.3 and OR = 1.1, 95% CI = 0.9–1.4, respectively). Furthermore, breakfast skipping was associated with a higher BMI (multivariable-adjusted OR = 1.05, 95% CI = 1.02–1.07). Conclusions: Our findings point to a strong and consistent positive relationship between breakfast skipping and obesity, but not overweight, among children in this transitional southeastern European population. Future studies in Albania and other transitional settings should prospectively examine the causal role of breakfast skipping in the development of overweight and obesity.

Objective: The last two decades have witnessed an increase in health care costs due to obesity and related issues among children and adolescents. Childhood obesity is a global phenomenon affecting all socio-economic groups, irrespective of age, sex or ethnicity. The study was done to find the the prevalence of obesity and overweight and their association with socioeconomic status (SES) and the risk factors. Materials and Methods: School based cross sectional study carried out over a period of 4 months in three schools of East Delhi. The study was carried out in 629 school children of 10–18 years of age and belonging to different socioeconomic statuses in schools in East Delhi. The obesity and overweight were considered using an updated body mass index reference. A pre-tested questionnaire was used to determine the Socio-economic status and life style factors. Results: The prevalence of overweight among children was higher in middle socioeconomic status groups as compared to high socioeconomic class in both boys and girls whereas the prevalence of obesity was higher in high Socio economic status group as compared to middle socioeconomic group. The prevalence of obesity as well as overweight in low SES group was the lowest as compared to other group. Conclusion: The findings of this study suggest that the prevalence of overweight and obesity varies remarkably with different socioeconomic development levels.

Purpose: In Canada, the incidence of childhood obesity has tripled within the past 20 years. The prevalence of obesity in the Timmins, Ontario, student population was studied to gain knowledge for program planning and resource allocation, and to compare Centers for Disease Control and Prevention (CDC) criteria with Cole’s international criteria for childhood obesity. Methods: Anthropometric measurements of 801 students were taken. Students were chosen from randomly selected schools for each grade. Data were analyzed according to age, gender, and ethnicity. Data were also compared with other studies. Intragroup comparisons were performed using hypothesis testing for significance with the z table and chi-square test. Results: Overweight and obesity prevalence was 28% according to CDC criteria. No statistical difference was found between genders or among ethnic groups, or between this study and other Canadian studies. In comparison with the CDC criteria, Cole’s international criteria indicated less obesity and increased overweight prevalence. These differences were not statistically significant. Conclusions: The findings suggest that in the northern Ontario community of Timmins, the prevalence of childhood obesity is of epidemic proportions. When the findings are shared with different agencies, this study will help the health unit to take necessary public health measures to curb the epidemic.

AbstractObjectivesSome factors in infancy can play a role in the development of adolescent obesity. Understanding these factors can help prevent early complications in adolescents associated with obesity in adulthood. The aim of this study was to determine the prevalence of overweight and obesity among high school girls in Khorramabad and its relationship with breastfeeding history.MethodsThis was a cross-sectional study. This study was conducted in 832 high school girls during the academic year 2016–2017. Samples were selected by multi-stage random sampling. General questionnaires, physical activity, and 24-h food questions were completed through interviews with students. Data regarding breastfeeding was obtained by mothers.ResultsThe prevalence of overweight and obesity in the study population was 16.3 and 5.8%, respectively. Overweight and obesity had a significant association with breastfeeding history (p = 0.001), while there was no significant relationship between overweight and obesity with school type, student’s age, parental occupation, education Parents, household size, birth rate, physical activity, and energy intake.ConclusionsThe results of this study showed that breast feeding has a protective effect on overweight and obesity during adolescence. To reduce the incidence of overweight and obesity, necessary education regarding breastfeeding should be provided.
