In the same manner, results from the National Health and Nutrition Examination Survey (NHANES) demonstrated that screen time appears to be a potential moderator of the relationship between physical activity and cardiovascular fitness in male adolescents with dyslipidemia. 23 Furthermore, previous data, involving a sample of 1,243 children and adolescents from our municipality, demonstrated that lipid profile alterations are more prevalent among obese/unfit children and adolescents in comparison with schoolchildren with normal or low weight, in both sexes. These results reinforce the findings of the present study and indicate a direct relation between the prevalence of dyslipidemia, obesity, and low levels of CRF. 6 734
