Objective: The objective was to investigate the association of PSC withmental health (i.e., depression and body image), physical status (i.e., fitness and weight status) andlifestyle (physical activity (PA) patterns and nutritional level) in Chilean schoolchildren. Methods: Atotal of 617 schoolchildren (n = 271 girls and n = 346 boys) aged 10–14 years participated in this study.Self-concept, depression and body image dissatisfaction were determined by questionnaires. Physicalfitness, PA, screen time (ST), Mediterranean diet (MD) adherence and anthropometric parameterswere also included. Results: Poor PSC was linked to bad cardiorespiratory fitness (CRF) (<42 VO2max)(OR 1.64; 95%CI 1.12–2.34; p = 0.01), severe body image dissatisfaction (OR 2.51, 95%CI 0.99–6.35;p = 0.05), ST of more than two hours a day (OR 2.1; 95%CI 1.41–3.12; p < 0.001), PA after school of nomore than two hours per week (OR 1.52; 95%CI 1.08–2.13; p = 0.015) and depression (OR 1.80; 95%CI1.1–2.92; p = 0.017). High nutritional level showed an association with general PSC and generalself-concept (p < 0.05). Absence of body image dissatisfaction was related to general self-concept(p < 0.01) and physical condition dimensions (p < 0.05). Conclusions: PSC is associated with CRF,PA after school, ST and nutritional level. According to mental health variables, poor PSC is relatedto depression in Chilean schoolchildren. Therefore, promoting a healthy lifestyle among childrenshould be a target of community- and school-based interventions to promote PSC.
