Abstract

The objective of this research was to associate the hours of screen consumption and physical activity with the BMI of adolescent schoolchildren from a private school in Joinville-SC. Materials and Methods - Participants were selected by probabilistic sampling of convenience. We evaluated the anthropometric index (BMI / age), the food consumption through a Food Frequency Questionnaire and the time of screen consumption and physical activity. The data was tabulated in Microsoft Excel Office 2010 and analyzed according to the descriptive statistics. Results - Out of the total number of adolescents (n = 47) investigated, 59.57% were girls, all students from a private school in Joinville / SC. Regarding the anthropometric evaluation, according to BMI / age, the mean of the girls was found in the P50 percentile with a mean BMI of 18.26 kg / m2; and the boys were between the P50 and P85 percentiles with a mean BMI of 19.65 kg / m2. About 80.85% of the adolescents made snacks between the main meals (lunch and dinner); 46.80% had four meals a day; 25.53% five or more meals daily; 27.65% two / three meals a day. In the school environment, the consumption of filled cookies (27.65%), fruits (23.40%), roasted salted (23.40%) were emphasized. It was observed that 51.06% of the investigated adolescents spent more than three hours watching television, playing games or surfing the internet. According to the WHO, the consumption of food with a high energy density is greater while it is in front of TV, video game and internet. Conclusion - The results obtained contributed to know the nutritional status of the population investigated, and the factors that can condition them.
