Contextual factors influencing leisure physical activity of urbanized indigenous adolescents

Abstract

Indigenous populations suffer from disparities in socioeconomic resources and health status. One approach to addressing these disparities is by targeting modifiable risk factors such as leisure physical activity (LPA). This study investigated and compared factors related to LPA among urbanized indigenous and nonindigenous adolescent students. Methods: This cross-sectional survey comprised fifth to ninth grade indigenous and nonindigenous students (n = 733). The nonindigenous students were matched with indigenous students on sex and academic achievement and used as a reference group. Data were collected through telephone interviews using structured questionnaires. Major items included: demographic characteristics; average time spent watching television per bout; participation in LPA; and stress and depression experiences. Results: With the exception of the duration of television watching per bout, Chi-square and independent t tests demonstrated that there were no significant differences between indigenous and nonindigenous adolescents in the selected LPA-related factors. Multiple logistic regression analysis including terms investigating interaction between ethnicity and the contextual factors included in this study indicated that the following factors were correlated with LPA participation: age [odds ratio (OR) = 0.82, 95% confidence interval (CI) = 0.71–0.94], male sex (OR = 1.77, 95%CI = 1.19–2.61), total hours spent watching television in the past 2 weeks (OR = 0.79, 95%CI = 0.63–0.99), life satisfaction (OR = 2.25, 95%CI = 1.04–4.90), and exercise enjoyment (OR = 3.40, 95%CI = 1.71–6.74). However, neither indigenous status (OR = 1.03, 95%CI = 0.19–5.79) nor any of the interaction terms reached the significant level. Conclusion: No significant ethnic differences were found in LPA participation. LPA was significantly correlated with age, male sex, total time spent watching television, life satisfaction, and enjoyment of exercise.
