Longitudinal Study on Correlations Between Body Image, Physical Activity, and the Subjective Well-Being Among Adolescents Aged 14–16

This is the authors' abstract. We don't add key points for this paper.

This study examined the relationship between physical activity, body image, and subjective well-being among Swedish adolescents over time. Surveying 2308 students, with 137 providing longitudinal data, we conducted a multivariate logistic regression analysis. No significant correlations were found between physical activity ( p = .268), body functioning ( p = .567), or body appearance ( p = .075) at age 14 and subjective well-being at age 16. Among control variables, sex ( p = .038) and subjective well-being at age 14 ( p = .013) showed significant correlations, while economic status did not ( p = .39). The correlation between a positive subjective well-being at age 14 and age 16 indicates the importance of impacting the sense of well-being early. Further longitudinal studies are needed to explore the potential long-term correlation between body image and adolescent subjective well-being.
