“…Rito et al (2012) reportou valores de 4.8% de magreza, idêntico ao reportado por Marques-Vidal, Ferreira, Oliveira, e Paccaud (2008) 4.7 para meninas e 5.3% para meninos. Sardinha et al (2011) indicaram uma prevalência de sobrepeso e obesidade menor à medida que a idade avança. No nosso estudo o valor de IMC médio aumentou o que poderá dever-se ao próprio crescimento ou aumento da massa muscular ou devido aos efeitos cumulativos do estado do IMC das idades anteriores (Gortmaker, Dietz, Sobol, & Wehler, 1987).…”

RESUMOO excesso de peso é cada vez maior entre da população escolar jovem. Uma vez que não é evidente qual a atitude dos alunos com sobrepeso e obesidade face à participação em atividades físicas e sua relação com o desempenho escolar pretendemos identificar os factores de influência no contexto da EF escolar. Participaram neste estudo 490 alunos dos 3º ciclo e ensino secundário, divididos por sexo. Os valores de IMC foram ajustados para sexo e idade e criados três grupos: Magreza; peso normal; e excesso de peso. Os valores dos resultados escolares foram normalizadas para uma escala de 1 a 5 valores. A participação em atividades desportivas, regularidade de prática e percepção do sucesso escolar foi medida por questionário. Após análise exploratória dos dados foram realizados os testes do Qui-quadrado, ANOVA e correlação de Pearson. O eta quadrado parcial (η²) foi reportado como medida da magnitude do efeito das diferenças verificadas nas ANOVAs. Foi considerado o valor de α de 0.05. Os resultados mostraram que alunos com excesso de peso e magreza reportaram menores níveis de atividade física em relação a alunos normoponderais (4.20±1.73, 4.06±1.77, 4.61±1.73; p=0.044; η²=0.01, resp.). A maior parte dos alunos definiu o seu sucesso escolar através da aprovação/transição de ano a par de boas classificações, tendo este grupo obtido níveis superiores de prática (4.57±1.71, p=0.03) Verificaram-se efeitos significativos da variável níveis de IMC nas classificações médias finais e na disciplina de EF, em que os alunos normoponderais obtiveram melhores classificações do que os alunos com excesso de peso. Além disso, verificaram-se correlações significativas entre as classificações de Português e Matemática (r=0.80; p<0.001), entre as classificações de EF e Português (r=0.36; p<0.001), e entre as classificações de EF e Matemática (r=0.42; p<0.001). Os alunos com sobrepeso apresentaram níveis inferiores de prática de atividade física quando comparados com os alunos com peso normal ou magros concomitantemente com um rendimento escolar inferior. Face aos resultados consideramos a prática de atividade física um fator com influência positiva no rendimento escolar em alunos dos ensinos básico e secundário.Palavras-chave: Atividade física, IMC, perceções de sucesso, rendimento escolar, EF. ABSTRACTOverweight is increasing among the school population being physical inactivity one of its main causes. Since it is not clear what kind of attitude do overweight and obese students have towards participation in physical activity and its relationship with academic performance we intend to identify the influencing factors in the context of physical education. Participated in this study 490 students from 3 rd cycle and secondary education, divided by gender. BMI values were adjusted for sex and age and three groups were created: leanness; normal weight; and overweight. The values of the academic performance were normalized to a scale of 1 to 5 points. Participation in sporting activities, regularity of practice and perception of academic...

“…In the European Union, the prevalence of childhood overweight and obesity is approximately 25 %, with Southern European countries showing the highest prevalence rates [25,57]. Indeed, in Portugal, 21.6 % of girls and 23.5 % of boys, ages 10 to 18 years, are overweight or obese [44]. Furthermore, according to some studies, more than 60 % of overweight/obese adolescents tend be obese as adults [19,39].…”

Dairy foods comprise a range of products with varying nutritional content. The intake of dairy products (DPs) has been shown to have beneficial effects on body weight and body fat. This study aimed to examine the independent association between DP intake, body mass index (BMI), and percentage body fat (%BF) in adolescents. A cross-sectional, school-based study was conducted with 1,001 adolescents (418 boys), ages 15-18 years, from the Azorean Archipelago, Portugal. Anthropometric measurements were recorded (weight and height), and %BF was assessed using bioelectric impedance analysis. Adolescent food intake was measured using a self-administered, semiquantitative food frequency questionnaire. Data were analyzed separately for girls and boys, and separate multiple linear regression analysis was used to estimate the association between total DP, milk, yogurt, and cheese intake, BMI, and %BF, adjusting for potential confounders. For boys and girls, respectively, total DP consumption was 2.6 ± 1.9 and 2.9 ± 2.5 servings/day (P = 0.004), while milk consumption was 1.7 ± 1.4 and 2.0 ± 1.7 servings/day (P = 0.001), yogurt consumption was 0.5 ± 0.6 and 0.4 ± 0.7 servings/day (P = 0.247), and cheese consumption was 0.4 ± 0.6 and 0.5 ± 0.8 servings/day (P = 0.081). After adjusting for age, birth weight, energy intake, protein, total fat, sugar, dietary fiber, total calcium intake, low-energy reporters, parental education, pubertal stage, and physical activity, only milk intake was negatively associated with BMI and %BF in girls (respectively, girls: β = −0.167, P = 0.013; boys: β = −0.019, P = 0.824 and girls: β = −0.143, P = 0.030; boys: β = −0.051, P = 0.548). Conclusion: We found an inverse association between milk intake and both BMI and %BF only in girls.

“…1 In Portugal, there is a high prevalence of overweight and obese children 2 and adolescents. 3 Patterns of physical activity (PA), sedentary time and nutrition appear to have an important role in long-term weight regulation. 4 In addition, it has been suggested that sedentary time during the first decades of life is linked to several health-related risks during adulthood.…”

AIM:The benefits of promoting physical activity (PA) in counteracting the high prevalence of childhood obesity have become increasingly important in the past decade. The aim of this study was to examine the association between compliance of daily PA recommendations and the risk of being overweight or obese in preschool-aged children. METHODS: The sample comprised 607 children aged 4-6 years, recruited from kindergartens located in the metropolitan area of Porto, Portugal. Preschooler's body mass index was classified according to International Obesity Task Force. PA was assessed during 7 consecutive days by accelerometer. Children were classified as meeting or not meeting PA recommendations based on two guidelines: (i) at least 3 h per day of total PA (TPA); and (ii) at least 1 h per day of moderate to vigorous PA (MVPA). RESULTS: The prevalence of overweight and obesity was 23.5 and 10.6% in girls and 17.2 and 8.9% in boys. In all, 90.2 and 97.3% of girls met the X1 h MVPA and X3 h TPA recommendations, respectively. In all, 96.2 and 99.4% boys met the X1 h MVPA and X3 h TPA recommendations, respectively. Boys were significantly more likely to achieve the X1 h MVPA and X3 h TPA recommendations than girls (Pp0.001). Not meeting the X1 h MVPA guideline was associated with obesity status (OR: 3.8; IC: 1.3-10.4), in girls, but not boys. No other statistically significant associations were found. DISCUSSION: These findings suggest that over 90% of children met the recommended guidelines. There is an association with low levels of MVPA and higher obesity status among preschool girls. Further, longitudinal studies are needed to confirm these data.
