The study comprised 474 children (242 males and 232 females, aged 8\u201313 years) selected in the Porto area of Portugal. The multiple regression analysis showed that the physical activity index is not associated with the variation in the biological risk factors in girls, while for boys a significant association was found for systolic blood pressure (R2 = .04, p= .05) and diastolic blood pressure (R2 = .03, p= .05). The present study shows that boys were significantly more active than girls, except for the young group (8\u20139 years old). However, except for SBP and DBP in males, no significant benefit from physical activity was related to the CVD risk factors evaluated. Since girls consistently reduce their levels of physical activity, some further attention should be given to this matter, mainly in the context of physical activity at school.<\/jats:p>","DOI":"10.1177\/1356336x010073003","type":"journal-article","created":{"date-parts":[[2007,3,10]],"date-time":"2007-03-10T22:40:31Z","timestamp":1173566431000},"page":"269-281","source":"Crossref","is-referenced-by-count":8,"title":["Physical
