Obesity in children is partly due to unhealthy lifestyle behaviours, e.g., sedentary activity and poor dietary choices. This trend has been seen globally. To determine the extent of these behaviours a Portuguese population children, 686 9.5 10.5 years age were studied. Our aims to: (1) describe profiles children’s behaviours; (2) identify behaviour pattern classes; (3) estimate combined effects individual/ socio-demographic characteristics predicting class membership. Physical sleep time...

The purpose of this study was to examine secular changes in growth and nutritional status Mozambican children adolescents between 1992, 1999 2012.3374 subjects (1600 boys, 1774 girls), distributed across the three time points (523 1992; 1565 1999; 1286 2012), were studied. Height weight measured, BMI computed, WHO cut-points used define status. ANCOVA models compare height, years; chi-square determine differences prevalence years.Significant for boys found height (p<0.05) points, where those...

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 shuttle‐run, sit‐and‐reach, and 1‐mile run/walk. Biological maturity was assessed by sexual characteristics, percentage body fat predicted using triceps subscapular skinfolds. ANCOVA...

Sedentary behaviour (SB) has been implicated as a potential risk factor for chronic disease. Since children spend most of their awake time in schools, this study aimed to identify individual- and school-level correlates sedentary using multilevel approach, determine if these have similar effect normal weight (NW) overweight/obese (O/O) children.Sample comprised 686 Portuguese aged 9-10 years from 23 schools that took part the ISCOLE project. Actigraph GT3X + accelerometers were used 24...

Methods sample comprises 501 (248 girls), aged 7‐10 years, classified as low weight, normal...

Sedentary behavior (SB) expression and its underlying causal factors have been progressively studied, as it is a major determinant of decreased health quality. In the present study we applied Genotype x Age (GxAge) Sex (GxSex) interaction methods to determine if phenotypic different SB traits influenced by an between genetic architecture both age sex. A total 1345 subjects, comprising 249 fathers, 327 mothers, 334 sons 325 daughters, from 339 families The Portuguese Healthy Family Study were...

The objective of this study is to present a model estimate sex-specific genetic effects on physical activity (PA) levels and sedentary behaviour (SB) using three generation families. sample consisted 100 families covering generations from Portugal. PA SB were assessed via the International Physical Activity Questionnaire short form (IPAQ-SF). Sex-specific by genotype-by-sex interaction (GSI) models heritabilities. GSI heterogeneity tested in residual environmental variance. SPSS 17 SOLAR v....

This study aimed to investigate the association between individual and school characteristics associated with number of days children comply moderate-to-vigorous physical activity (MVPA) recommendations. Sample comprises 612 Portuguese children, aged 9-11 years, from 23 schools. Time spent in MVPA was measured by accelerometry, while individual-level correlates were obtained anthropometry questionnaires. School-level variables collected questionnaire, accelerometer wear time season also...

Family studies are well suited to investigate the genetic architecture underlying metabolic syndrome (MetS). The purposes of this paper were (i) estimate heritabilities for each MetS indicators, and (ii) test significance familial intratrait cross-trait correlations in markers.This study included 1,363 individuals from 515 Portuguese families which five components, including waist circumference (WC), blood pressure (BP), HDL-cholesterol, triglycerides (TG), glucose (GLU), measured....

Somatotype is a complex trait influenced by different genetic and environmental factors as well other covariates whose effects are still unclear.To (1) estimate siblings' resemblance in their general somatotype; (2) identify sib-pair (brother-brother (BB), sister-sister (SS), brother-sister (BS)) similarities individual somatotype components; (3) examine the degree to which between within variances differ among sib-ships; (4) investigate of physical activity (PA) family socioeconomic status...

This study investigated the association of six different anthropometric markers with metabolic syndrome to find most suited predict children at risk. Sample comprises 1324 Portuguese youth (701 girls, 623 boys), aged 10‐17 years. Six were included: body mass index (BMI), BMI z‐score, tri‐ponderal (TPI), waist circumference (WC), WC/height ratio (WC/H), and WC/H adjusted (WC/H adj ). A standardized risk score (zMR) was computed by summing values for fasting glucose, triglycerides,...
