Abstract

OBJECTIVES:

To analyze the relationship between different physical activity (PA) domains and sociodemographic, psychological, behavioral and biological factors in Brazilian adolescents.

METHODS:

1,220 adolescents (55.1% female) aged between 10 and 16 years-old participated in this study. The Baecke questionnaire was used to evaluate different PA domains, namely occupational, sports and leisure-time. Socioeconomic status, number of siblings, friendships satisfaction, mother's and father's PA level and previous experience with sports were self-reported. Cardiorespiratory fitness, waist circumference, and somatic maturity were estimated by objective indicators. Linear regression was used for the main statistical analysis.

RESULTS:

The variables consistently related to all of the PA domains were gender (boys more active), friendship satisfaction (positive with sports and leisure-time PA and negative with occupational PA) and cardiorespiratory fitness (positive). There were also domain-specific relationships for occupational (number of siblings [β = 0.02] and father's PA [β = 0.13]), sport practice (previous experience with sports [β = 0.33], waist circumference [β = 0.01] and somatic maturity [β = -0.12]) and leisure-time PA (chronological age [β = -0.15], mother's PA [β = 0.47] and previous experience with sports [β = 0.17]).

CONCLUSIONS:

The different domains of PA are related to specific variables in adolescence. This information may be helpful in formulating strategies for physical activity promotion, particularly in adolescents from low-to-middle income countries.
