Overweight and Obesity Prevalence Among School-Aged Nunavik Inuit Children According to Three Body Mass Index Classification Systems

Background: Prevalence of obesity in youths has drastically increased in both industrialised and non-industrialised countries, and this transition resulted in an increased prevalence of chronic diseases.Aim: The study aimed to comparatively examine prevalence of overweight and obesity status based on tri-ponderal mass index and body mass index in estimating body fat levels in South African children.Setting: The study was conducted in Limpopo and Mpumalanga provinces of South Africa.Methods: A cross-sectional survey of 1361 (boys: n = 678; girls: n = 683) children aged 9–13 years was undertaken. The children’s age and sex-related measurements of body weight, waist-to-height ratio, waist-to-hip ratio, triceps skinfold, subscapular skinfolds and sum of skinfold were taken using the International Society for Advancement of Kinanthropometry protocol. TMI and BMI calculations classified children according to weight and age categories. Descriptive statistics, Spearman’s correlations and multiple linear regression analyses were set at ≤ 0.05.Results: Obesity classifications on TMI and BMI among children were as follows: Boys: 7.3%, 2.6%; 2.2%, 0.7%; Girls: 4.0%, 1.0%; 1.8%, 0.6%. Body weight, WHtR, WHpR, TSKF, SSKF and ΣSKF significantly correlated with TMI (r = 0.40, p 0.001; r = 0.73, p 0.001; r = −0.09, p 0.001; r = 0.50, p 0.001; r = 0.51, p 0.001 and r = 0.52, p 0.001) and BMI (r = 0.81, p 0.001; r = 0.59, p 0.001; r = −0.22, p 0.001; r = 0.63, p 0.001; r = 0.67, p 0.001 and r = 0.66, p 0.001). Regression analysis revealed that body weight, WHtR, WHpR, TSKF, SSKF and ΣSKF accounted for 65% and 85% of variance in children’s TMI (R2 = 0.647, F[6 1354] = 413.977, p 0.001) and BMI (R2 = 0.851, F[6 1354] = 1288.218, p 0.001).Conclusion: TMI revealed strikingly higher incidence of overweight and obesity in South African boys and girls than BMI. Future studies are needed to clarify sensitivity of TMI over BMI in quantifying obesity prevalence in children and adolescents.

Objective: Prostate-specific antigen (PSA) is widely used as a screening tool of prostate cancer, although there has been a controversy about efficacy. In Korea, rapid growth of obesity prevalence in adult men is a one of the biggest health problems. The objective of this study was to evaluate the potential association between body mass index (BMI), waist circumference (WC) and PSA.Methods: We calculated BMI and WC of a total of 25,603 males who visited the Soonchunhyang University Cheonan Hospital Health Promotion Center from January 2016 to December 2020. This was categorized as follows: BMI < 23 kg/m2 (normal), 23 kg/m2 ≤ BMI < 25 kg/m2 (overweight), BMI ≥ 25 kg/m2 (obesity) and WC < 90 cm (normal), WC ≥ 90 cm (abdominal obesity). We analyzed the association between BMI, WC and PSA.Results: The mean PSA value was 1.08 ng/mL, 1.03 ng/mL, and 0.97 ng/mL at normal, overweight, and obesity group, respectively. The mean PSA value was 1.04 ng/mL and 0.96 ng/mL at normal and abdominal obesity group. Thus, the mean PSA value decreased with an increase in BMI and WC category (P < 0.001). The correlation coefficient between BMI, WC and PSA was -0.055, -0.044 and they were statistically significant (P < 0.001).Conclusion: We observed a significant negative correlation between BMI, WC and PSA value. Therefore, PSA value should be considered in relation to BMI and WC.

Migrant Domestic Workers

Background: Migrant domestic workers are at high risk of overweight and obesity. It is crucial to assess the prevalence of obesity among this migrant population, for surveillance and intervention. Self-reported height and weight are commonly used to derive body mass index (BMI) and assess the prevalence of obesity. The accuracy of BMI from self-reported height and weight in migrant populations remains unknown. The aim of this study was to assess the accuracy of BMI from self-reported measures and identify the optimal adjustment to be made to overweight and obesity cut-off points when using self-reported body mass index among migrant workers. Methods: Self-reported and objectively measured height and weight were obtained from 1388 female Filipina domestic workers and 369 female Indonesian domestic workers recruited using respondent-driven sampling between November 2016 and August 2017. Self-reported BMI (based on self-reported height and weight) and measured BMI (based on objectively measured height and weight) were calculated as weight in kilograms divided by the square of height in meters for all participants (kg/m2). Results: BMI derived from self-reported height and weight was underestimated for both Filipina (z = −27.5, p < 0.001) and Indonesian (z = −9.9, p < 0.001) participants. Applying the gold standard of Asian BMI cut-off points to self-reported BMI, the sensitivity in identifying overweight or obesity was 64.4% for Filipina participants and 78.6% for Indonesian participants and the specificity was 97.9% for Filipina participants and 93.8% for Indonesian participants for overweight or obesity. When self-reported measures were used, the receiver operator characteristic (ROC) curves and the corresponding area under the curve (AUC) indicated optimal cut-off points of 22.0 kg/m2 and 22.3 kg/m2 for Filipina and female Indonesian participants for overweight or obesity. Conclusions: Although BMI derived from self-reported height and weight allows for quick and low-cost obesity screening, a considerable underestimation of overweight or obesity prevalence was observed in Filipina and female Indonesian migrant domestic workers in Macao (Special Administrative Region, SAR), China. With the best compromise between sensitivity and specificity, the new cut-off points can be used in future studies to identify overweight or obesity in these two populations using self-reported height and weight.

Introduction. The aim of the study. The investigation of the time-related dynamics of adiposity parameters in a socially and economically homogenous group of young people. To determine the pattern of change in their health parameters and assess the prevalence of different diseases associated with increased body weight. Materials and methods. This study used the research titled "Massive anthropometric monitoring of physical development parameters of children, teenagers, and students" conducted from 2000 to 2018. The body mass index (BMI) of more than 6,400 students aged 17-18 years (2,971 young males and 3,418 young females) was examined. Then, we calculated the prevalence of underweight, overweight, and obesity among them. To determine the degrees of obesity, we compared the BMI values in our study with the World Health Organization's BMI ranges for corresponding age. Results. Over the study period, the mean BMI values and 5th and 15th BMI percentiles were characterized by weak positive time-related trends. Furthermore, 85th and 95th percentiles demonstrated a higher rate of increased data values (female students). From 2000 to 2018, the prevalence of overweight among female students increased from 5.2% to 10.5%, and that of obesity rose from 1.7% to 4.6%. For male students, no significant increase occurred in the overweight prevalence. Conclusions. To prevent chronic diseases associated with increased fat mass, attention should be paid to the mean values of different overweight parameters and the prevalence of extreme meanings in extensive population observations. Increased BMI among young females aged 17-18 years implies their possible elevated risk of cardiovascular diseases and other associated disorders later in life, related to nutrition disorders and lifestyle.

Objectives: To retrospectively investigate the reliability of the age-based formula, year/4 + 3.5 mm in predicting size and year/2 + 12 cm in predicting insertion depth of preformed endotracheal tubes in children and correlate these data with the body mass index. Patients and Methods: Patients were classified into 4 groups according to their nutritional status: thinness, normal weight, overweight, and obesity; we then retrospectively compared the actual size of endotracheal tube and insertion depth to the predicting age-based formula and to the respective bend-to-tip distance of the used preformed tubes. Results: Altogether, 300 patients were included. The actual endotracheal tube size corresponded with the Motoyama formula (64.7%, 90% CI: 60.0-69.1), except for thin patients, where the calculated size was too large (0.5 mm). The insertion depth could be predicted within the range of the bend-to-tip distance and age-based formula in 85.0% (90% CI: 81.3-88.0) of patients. Conclusion: Prediction of the size of cuffed preformed endotracheal tubes using the formula of Motoyama was accurate in most patients, except in thin patients (body mass index < −2 SD). The insertion depth of the tubes was mostly in the range of the age-based-formula to the bend-to-tip distance.
