Objective: This study aims to (1) investigate differences in weight, body mass index (BMI), and waist circumference (WC) among Peruvian children and ado lescents living in three areas located at different altitudes; (2) compare age and sex-specific height, weight, and BMI within each site with US reference data. Methods: We sampled 8753 subjects (4130 boys), aged 4 to 17 years from sea level, rainforest, and hi...
This study aimed to (1) estimate age-at-mid-growth spurt (age-at-MGS) in Portuguese boys from two different regions—the Azores islands and Viana do Castelo, and (2) identify spurts in a variety of physical fitness (PF) components aligned by age-at MGS in the two samples. A total of 176 (Azores, n = 91; Viana do Castelo, n = 85) boys aged 6 years old were followed annually to 10 years of age. Age-at-MGS and spur...
We aim to (1) estimate age of attainment of the peak mid-growth spurt in stature (age-at-peak MGS) in pre-adolescent boys and girls; (2) identify the timing, intensity, and sequences of physical fitness (PF) spurts aligned by the age-at-peak MGS; and (3) identify any sex differences in PF spurts aligned by age-at peak MGS. The sample included 180 Portuguese children (90 girls) aged 6 to 10 years at study entry ...
This study investigated the associations between biological and environmental factors and gross-motor coordination (GMC) in Peruvian children and adolescents. The sample comprised 7401 boys and girls, aged 6–14 years, recruited from three geographical regions: sea-level, Amazon and high-altitude. Biological variables included age, sex, height, BMI, physical fitness, stunting, and maturational status. Environmen...
Background: Data relating physical performance to the timing of the adolescent growth spurt are lim ited. Aim: This study identifies: (i) age-at-peak height velocity (APHV), (ii) physical performance spurt patterns aligned to APHV; and (iii) cross-cultural and time patterns in Canadian, Brazilian and Portuguese boys. Subjects and methods: A total of 512 boys (131 Canadian, 250 Portuguese and 131 Brazilian), 8–1...
This study aimed to jointly analyse moderate-to-vigorous physical activity (MVPA) and sedentariness, and their correlates, in children within their school contexts, using a multivariate multilevel approach. The sample comprises 499 Portuguese children (284 girls) from 23 schools. MVPA and sedentary time were estimated by accelerometer. A set of predictor variables from both child and school levels was tested. O...
Objectives: The aims of this study were (1) to identify the timing of the mid growth spurt (MGS) in stature in children and (2) to identify gross motor coordina tion (GMC) spurts when aligned by the age of attainment of the MGS (aMGS). Methods: Stature, weight, and GMC were measured in 245 Portuguese children followed annually from 6 to 10 years. GMC was assessed and to estimate children's MGS in stature as wel...
Background: The development of gross motor coordination (GMC) is governed by biological and environmental factors whose effect sizes are still unclear. Aim: To investigate sibling resemblance in GMC, as well as biological and environmental correlates of GMC among Peruvian children. Materials and methods: The sample comprised 1256 biological siblings (6–15 years old), from three geographical areas of Peru. GMC w...
