Background: Studies concerning child and adolescent growth, development, performance and health aimed at the multiple interactions amongst this complex set of variables are not common in the Portuguese speaking countries.
Aim: The aim of this paper is to address the key ideas, methodology and design of the Oporto Growth, Health and Performance Study (OGHPS).
Subjects And Methods: The OGHPS is a multidisciplinary mixed-longitudinal study whose main purpose is to examine the multiple interactions among biological, environmental and lifestyle indicators that affect growth, development, health and performance of Portuguese adolescents aged 10-18 years old.
Objective: This study presents information about secular trends in physical fitness (PF) levels among Mozambican youth.
Methods: The sample comprises 3,851 subjects (1,791 boys; 2,060 girls) aged 8-15 years who were evaluated at three time points (1992, 1999, 2012). PF tests included handgrip strength, 10 m × 5 m shuttle-run, sit-and-reach, and 1-mile run/walk.
Background: Few studies focus on the different dyadic relations among family members to study physical activity (PA) levels.
Aim: The aim was to investigate predictors and sources of variance of PA levels in nuclear families using multi-level modelling.
Subjects And Methods: The sample consisted of 2661 Portuguese four-member nuclear families (10 644 subjects).
Background: Except for North America and Europe, few studies have reported the association among physical activity (PA), cardiorespiratory fitness (CRF) and metabolic syndrome (MetS) in youths, especially for rural African youth.
Aim: The aims of this study were to determine the prevalence of PA levels, CRF, MetS and its indicators, and examine the association between these variables in a school-aged sample of youth from rural Mozambique.
Subjects And Methods: The sample included 209 children and adolescents aged 7-15 years old from Calanga, a rural community in Mozambique.
