Submandibular Skinfold Thickness Cut–off Values in Relation to Body Mass Index and Percentage Body Fat Among Chilean Adolescents
The present study evaluates submandibular skinfold (SMS) cutoff values to estimate excess weight for BMI and percentage body fat (%BF) among Chilean adolescents. The results show an optimal area under the cutoff curve value of 83% among girls and 91% in boys to estimate SMS concerning %BF and BMI. The SMS cutoff value estimating obesity by %BF was 10 mm among girls and 9 mm among boys, 10 mm among girls, and 7 mm among boys by BMI. Our results sh…
Musculoskeletal Disorders Associated With Quality of Life and Body Composition in Urban and Rural Public School Teachers
Introduction: Teachers have been reported to be a labor group with high rates of musculoskeletal disorders (MSDs), stress, and strong deterioration of quality of life (QoL). However, little information exists about the association between MSD, QoL, and body composition in rural and urban teachers. Objective: The aim was to study the association of MSD with QoL perception and body composition of urban and rural teachers. Participants and Methods: …
Impact of the Covid-19 Pandemic on Teacher Quality of Life
Prior to the COVID-19 pandemic, teachers were already reporting a low quality of life (QoL) perception, with a significant impact on mental and physical health due to various stress factors associated with work overload. The objective of this study was to evaluate the QoL impact on Chilean teachers before and during the COVID-19 pandemic. The analysis was performed following a longitudinal design on a sample of 63 Chilean teachers in pre-pandemic…
Women’s perceptions about changes in food-related behaviours at home during Covid-19 pandemic in Chile
Objective: To explore women’s perceptions of changes in specific food habits at home, specifically the food budget and shopping, and food preparation, during the COVID-19 period. Design: Non-probabilistic, exploratory study. Participants completed an online self-administered questionnaire. Perceptions of food habit changes were measured on a five-point Likert scale (strongly disagree to strongly agree). Data analysis was conducted in STATA v16.0.…
Academically Oriented Activity Breaks for First-Grade Chilean Students
We developed and pilot tested the effectiveness of a physically active academic program, Active Breaks (AB), whose objective is to increase school time moderate/vigorous physical activity (MVPA) among first graders, through daily 15-minute bouts of MVPA, at the beginning of the first lesson. Initially, 240 cards including one game each were developed and tested in first-grade students from 16 schools in Santiago. Trained observers and school teac…
Association Between Body Composition, Somatotype and Socioeconomic Status in Chilean Children and Adolescents at Different School Levels
This study examined the association between body composition, somatotype and socioeconomic status (SES) in Chilean children and adolescents by sex and school level (grade). The cross-sectional study was conducted on 1168 schoolchildren aged 6–18 years (572 males) from Valparaíso, Chile. Body composition, as assessed by percentage body fat (BF%) and somatotype, was evaluated using Ellis equations and the Heath–Carter method, respectively. The soci…

Association between Socioeconomic Vulnerability and Height with Obesity in Low-Income Chilean Children in the Transition from Preschool to First Grade
This study determined the percentage of obesity among lower-income Chilean children 4-6 years of age, by socioeconomic vulnerability (family score assessing the children's risk of becoming poor) and height. The sample included 17,080 children with anthropometry at 4, 5, and 6 years of age, and three categories of socioeconomic vulnerability. Body mass index Z-score (BMI Z), % obesity, height/age Z-score (HAZ) by socioeconomic vulnerability/sex, t…
Two-year controlled effectiveness trial of a school-based intervention to prevent obesity in Chilean children
Objective Obesity prevalence among Chilean children is 19·4 %. The present study aimed to assess the effectiveness of a school-based obesity prevention programme. Design Non-randomized controlled study. The intervention included activities in nutrition and physical activity, fully applied the first year and partially in the second one. Primary outcomes were BMI Z -score (BMIZ) and obesity prevalence; secondary outcomes were waist circumference an…
