Objective: The prevalence of overweight and obesity among children and adolescents increased dramatically. Reduced regular physical activity (PA) is considered one of the major factors behind this worldwide epidemic and related health problems. This study aimed to determine the association between PA level and body composition components in 12-14 years old girls and boys living in Altındağ district, Ankara.

Materials and methods: A total of 234 boys and 224 girls aged 12-14 years participated in this study. PA level was assessed by the Physical Activity Questionnaire for Children (PAQ-C) and body composition was measured by bioelectric impedance. Two-way ANOVA with Bonferroni post hoc test and Pearson Correlation Coefficient tests were used in data analysis.

Results: Findings of the study showed that children aged 12 years had higher total PA score than aged 13 and 14 years (p<0.05), showing decreased PA level with age. Boys had significantly higher total PA score in all age groups than girls (p<0.05). Girls with healthy weight and overweight showed significantly higher total PA score than girls with obesity. Girls had higher fat mass and body fat percentage than boys in all age groups (p<0.05). Fat mass was inversely associated with total PA score in all age groups (12 years old r=-0.28; p<0.001, 13 years old r=-0.16; p=0.047, 14 years old r=-0.21; p=0.007).

Conclusions: PA participation of children declines with age. Reduced PA level is significantly associated with increased fat mass, indicating the importance of PA in maintaining a healthy weight in this age group.
