Physical activity, self-acceptance, and body perception among Peruvian university students: an analysis using partial least squares structural equation modeling

Introduction: University students face challenges related to body image, pressure to meet appearance standards, and sedentary lifestyles. Evidence examining these factors together with psychological well-being remains limited in Peru. Objective: The study examined relationships between physical activity, self-acceptance, personal growth, and the subjective importance of appearance and fitness among Peruvian university students. Methodology: A quantitative, nonexperimental, cross-sectional study included 400 students from Peru, primarily from Lima and Chiclayo, selected through convenience sampling. Questionnaire data were analyzed using partial least squares structural equation modeling. Results: Most constructs showed adequate convergent and discriminant validity, although the Physical Activity construct showed limited internal consistency. Self-acceptance was significantly associated with personal growth, and the subjective importance of appearance was significantly associated with self-acceptance. Physical activity was not significantly associated with self-acceptance directly. Predictive performance was limited. Discussion: The findings were considered alongside research on eudaimonic well-being, body-related experiences, and university sport participation. Differences in constructs and measurement limited direct comparisons across studies. Conclusions: The findings support considering physical activity, body-related perceptions, and self-acceptance together in university well-being initiatives, while highlighting the need for improved measurement and further predictive validation.
