The study summarizes the findings of 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents compares results with first RC other countries from Global Matrix 3.0.A Research Work Group using a standardized methodology 3.0 awarded grades 13 PA-related indicators based percentage compliance defined benchmarks. Different public data sets, government reports, papers informed indicators.The assigned were (1) "behaviors that contribute to overall PA levels": PA, D-;...
Dyslipidemias in childhood increase the risk of cardiovascular events adult life.To evaluate prevalence dyslipidemia and atherogenicity based atherogenic index plasma (AIP) a sample school children adolescents.Cross-sectional study 208 aged 10.4 ± 1.0 years (107 women). Demographic data were obtained, clinical evaluation was conducted, including pubertal development according to Tanner anthropometric parameters. A fasting blood obtained measure total cholesterol (CT), HDL (cHDL)...
Childhood and adolescent obesity is a major public health problem in Chile.To characterize cardiometabolic risk factors population of schoolchildren from Carahue, Chile.Cross-sectional assessment 208 children aged 10.4 ± 1.0 years (106 women). A clinical evaluation was carried out including pubertal development according to Tanner anthropometric parameters. fasting blood sample obtained measure glucose, insulin lipid profile. HOMA-IR Quicki indices were calculated. Insulin resistance (IR)...
The purpose was to determine the proportion of 9- 11-year-old children meeting 24-hour movement guidelines (24-HMG) in a low-income town from Chile.Physical activity, sedentary behavior (recreational screen), and sleep times were measured with both questionnaire accelerometer 258 third sixth grade. Meeting 24-HMG defined as having ≥60 minutes per day moderate vigorous physical ≤2 hour screen time, 9 11 hours night. Compliance rates calculated self-reported 24-HMG, all estimations based on...
Abstract. Background: Little is known about of correlates physical activity (PA), sedentary behaviour (SB), and sleeping in children from Latin America. The aim this study was to assess the association between potential with device-measured PA, SB time 9 11 years Carahue, Chile. Methods: A cross-sectional conducted behaviours (demographic, psychological, behavioural, home school environment factors) data reported by participants caregivers. Each participant wore an ActiGraph GT3X+...
Although evidence on the health effects of sedentary behavior (SB) has grown systematically in recent years, few developing countries have reported population levels SB, especially South America. Our objective was to describe time spent sitting a representative sample from Chile categorized by age, gender, educational level, and body mass index (BMI).A national survey conducted nationally (n = 5411) 2009-2010. Sitting (ST) measured with Global Physical Activity Questionnaire Version 2.Data...
Given the importance of physical activity and sleep for health, different recommendations have been proposed pediatric population. The objective this study was to determine association between compliance excess weight in school children from Temuco, Chile.Physical were measured using ActiGraph wGT3X-BT® accelerometers. Excess categorized on two categories: absence (normal weight) or presence (overweight obesity) based body mass index.A total 183 participated (54.1 % females; mean age = 10.95...
The aim of this study was to compare self-reported with two accelerometer-derived methods classify Chilean children and adolescents as physically active. In total, 247 students wore an accelerometer on their hips during 7 consecutive days them active based (1) daily accumulation ≥ 60 minutes moderate-to-vigorous physical activity (MVPA) each the seven days, (2) average MVPA minutes/day. Also, participants were classified if they reported being for at least in all days. When using data, 0.8%...
Abstract. Background: Device measured physical activity (PA) allow better understanding on how PA is accrued during days. The purpose of this study was to describe pedometer-derived levels and patterns by gender in a population Chilean children. Methods: 100 children were randomly selected from two low-income neighborhoods Santiago, Chile. with wrist-worn pedometer for 7 consecutive Steps summarized as total steps per hour day. hourly-patterns compared across subgroups age, gender, residence...
Abstract Background To better understand sedentary behaviour and favour international comparisons, more evidence from different countries are needed. However, there a few tools available in Spanish to measure behaviour. This study aimed culturally adapt, translate validate the Past-day Adults’ Sedentary Time (PAST) questionnaire Chilean adults compared with ActivPAL. Method One hundred one workers wore an ActivPAL for 1 week were asked respond version of PAST twice on visits at 7-day...
PURPOSE: To describe device measured physical activity (PA) and sedentary behaviour (SB) in older adults from Temuco, Chile. METHODS: Community-dwelling aged 60 were recruited 17 different neighbourhoods The participants asked to wear an ActiGraph GT3X+ accelerometer on the hip for 7 consecutive days. A sleeping a non-wear-time algorithms used detect daily wearing time. Accelerometer data considered valid if participant wore at least 8 hours any 4 days of week. vector magnitude counts (cpm)...
