Abstract
PURPOSE:This article aims to explore the influence of different dimensions of home-based environment on the physical activity (PA) of adolescents in different genders and provide evidence for developing home-based PA promotion strategies in the future. METHODS:A total of 314 adolescents were selected with randomly sampling. The adolescents’ PA of various intensity were determined with the ActiGraph GT3X-BT accelerometer and the home-based physical (i.e. PA availability, PA accessibility) and social (i.e. parental role-modeling of PA, parental encouragement around PA) environmental characteristics were evaluated using the Gattshall’s home-based PA environment questionnaire. The multiple linear regression analysis in adjusted model was used to evaluate the influence of different home-based PA environment on sedentary behavior (SB), light-intensity PA (LPA) and moderate-vogirous PA (MVPA) of adolescents. RESULTS:According to the results of the multiple regression model, the PA availability (β = -162.49, p < 0.01), father’s modeling (β = -308.42, p < 0.05), mother’s modeling (β = -317.76, p < 0.01) and mother’s encouragement (β = -254.66, p < 0.05) around PA are the major influential factors of boys’ SB; the PA availability (β = -46.47, p < 0.05) and father’s encouragement (β = -60.70, p < 0.05) are the major influential factors of girls’ SB. The PA availability (β = 18.39, p < 0.01) and mother’s encouragement (β = 12.89, p < 0.01) are the major influential factors of boys’ LPA; the PA availability (β = 10.41, p < 0.05) and father’s encouragement (β = 9.81, p < 0.05) are the major influential factors of girls’ LPA. The PA availability (β = 70.85, p < 0.01) and mother’s modeling (β = 44.41, p < 0.05) are the major influential factors of boys’ SB; the father’s encouragement (β = 49.80, p < 0.05) is the major influential factor of girls’ MVPA. CONCLUSIONS:There is a difference in the influence of home-based physical and social environment on Chinese adolescents in different genders.
