Genetic regulation of body size and morphology in children: a twin study of 22 ...
Silventoinen, Karri; Maia, José; Li, Weilong; Sund, Reijo; Gouveia, Élvio R.; Antunes, António; Marques, Gonçalo; Thomis, Martine; Jelenkovic, AlineAnthropometric measures show high heritability, and genetic correlations have been found between obesity related traits. However, we lack a comprehensive analysis of the genetic background of human body morphology using detailed anthropometric measures. METHODS: Height, weight, 7 skinfold thicknesses, 7 body circumferences and 4 body diameters (skeletal breaths) were measured in 214 pairs of twin children aged ...
Genetics of somatotype and physical fitness in children and adolescents
Silventoinen, Karri; Maia, José; Jelenkovic, Aline; Pereira, Sara; Gouveia, Élvio; Antunes, António; Thomis, Martine; Lefevre, Johan; Kaprio, JaakkoObjectives: To analyze the influence of genetic and environmental factors on the variation in somatotype, physical fitness, and their mutual associations. Methods: Twins from 214 pairs (87 monozygotic) of the Autonomous Region of Madeira, Portugal, from 3 to 18 years of age (51% girls) were assessed in anthropometry and physical fitness tests. We estimated endomorphy, meso morphy, and ectomorphy based on anthro...
Motor performance, body fatness and environmental factors in preschool children
Antunes, António M; Freitas, Duarte L.; Maia, José; Hedeker, Donald; Gouveia, Élvio R; Thomis, Martine; Lefevre, Johan; Barnett, Lisa MThe first aim of this study was to investigate the relationship between motor performance and body fatness among 3- to 5-year-old children. The second aim was to assess whether this relationship works similarly for boys and girls. We also investigated whether socioeconomic status (SES) and geographical area when children are aged 3 years old predicts the motor performance of 4 and 5-yr-old children. Motor perfo...
Biological and environmental determinants of 12-minute run performance in youth
Freitas, Duarte; Maia, José; Stasinopoulos, Mikis; Gouveia, Élvio Rúbio; Antunes, António M.; Thomis, Martine; Lefevre, Johan; Claessens, AlbrechtBackground: The 12-minute run is a commonly used indicator of cardiorespiratory fitness in youth. Variation in growth and maturity status as potential correlates of test performance has not been systematically addressed. Aim: To evaluate biological and environmental determinants of 12-minute run performance in Portuguese youth aged 7–17years. Subjects and methods: Mixed-longitudinal samples of 187 boys and 142 ...
The genetic background of metabolic trait clusters in children and adolescents
Silventoinen, Karri; Gouveia, Élvio; Jelenkovic, Aline; Maia, José; Antunes, António M.; Carvalho, Miguel Â. A. Pinheiro de; Brehm, António M.Background: It is well known that the metabolic risk factors of cardiovascular diseases are correlated, but the background of this clustering in children is more poorly known than in adults. Thus, we studied the contribution of genetic and environmental factors to the clustering of metabolic traits in childhood and adolescence. Methods: Nine metabolic traits were measured in 214 complete twin pairs aged 3 to 18...
Skeletal maturation, body size, and motor coordination in youth 11-14 years
Freitas, Duarte Luís; Lausen, Berthold; Maia, José António Ribeiro; Gouveia, Élvio Rúbio; Thomis, Martine; Lefevre, Johan; Silva, Ricardo DinisPurpose: The objective of this study is to estimate the relative contribution of biological maturation to variance in the motor coordination (MC) among youth and to explore gender differences in the associations. Methods: Skeletal maturation (Tanner-Whitehouse 3), stature, body mass, and MC (Ko¨rperkoordinationstest fu¨rKinder) were assessed in 613 youths, 284 boys and 329 girls 11–14 yr of age. Standardized re...
Prevalência de sobrepeso e obesidade em crianças e adolescentes da Região Autón...
Gouveia, Élvio; Freitas, Duarte; Maia, José; Beunen, Gaston; Claessens, Albrecht; Marques, António; Thomis, Martine; Almeida, Sara; Lefevre, JohanO objectivo foi estimar a prevalência de sobrepeso e obesidade em crianças e adolescentes da Região Autónoma da Madeira, Portugal. Um procedimento estratificado proporcional foi usado para obter uma amostra representativa de crianças e adolescentes madeirenses dos 7 aos 18 anos. No total, 2503 sujeitos, 1266 rapazes e 1237 raparigas, participaram no estudo. A prevalência de sobrepeso e obesidade foi definida a ...
Association between birth weight and neuromotor performance: a twin study
Lopes, Alfredo; Tani, Go; Katzmarzyk, Peter; Thomis, Martine; Maia, JoséThe development of neonatal intensive care has led to an increase in the prevalence of children with low birth weight and associated morbidity. The objectives of this study are to verify (1) The association between birth weight (BW) and neuromotor performance? (2) Is the neuromotor performance of twins within the normal range? (3) Are intra-pair similarities in neuromotor development of Monozygotic (MZ) and Dis...
Physical activity, physical fitness, gross motor coordination, and metabolic sy...
Maia, José António Ribeiro; Santos, Daniel; Freitas, Duarte Luís de; Thomis, MartineA very brief history of Portuguese twin research in sport and human movement sciences is presented. Recruitment procedures, zygosity determination, and phenotypes are given for twins and their parents from the mainland, and Azores and Madeira archipelagos. Preliminary findings are mostly related to physical activity, health-related physical fitness, gross motor coordination, neuromotor development, and metaboli...
