Abstract
Objective: The aim of this study was to determine the prevalence of overweight and obesity
in children in the northeast region of Portugal, and to examine its association with sedentary
behavior.
Methods: Data were collected on 1786 children (907 boys, 879 girls) aged 6 to 13 years. Body
mass index was calculated from measured height and weight (weight in kg/height in m squared).
Overweight and obesity were determined using the International Obesity Task Force cutoff
values. Sedentary behavior was assessed based on means of transport to and from school and
time spent watching TV and playing video games (TVPC).
Results: The prevalences of overweight and obesity were 22.6% and 9.4% respectively. The
differences between the sexes for both overweight and obesity were not significant. Most of
the children (78.4%) go to school by car. Boys spend more time on TVPC than girls, both on
weekdays and on weekends. The logistic regression model indicated a significant effect of 1.5
hours of TVPC by boys during weekdays (OR=0.246; p=0.015). Boys who spent less than 1.5 hours
on weekdays on TVPC were 75.4% less likely to be overweight than those who spent more than
1.5 hours.
Conclusion: The prevalence of overweight and obesity was 32%. Only 12.2% of the children
spend less than 1.5 hours on TVPC. Boys who spend less than 1.5 hours on TVPC are 75.4% less
likely to be overweight/obese than those who spend more than 1.5 hours.
