Assessments included body mass index, waist circumference, the Índice de Calidad de la Alimentación y Protección en Adolescentes (ICAPA), and the adolescent personality assessment inventory.SummaryOverweight/obesity prevalence was 42.4%, being higher in males and rural settings; 32% exhibited cardiometabolic risk. Most participants (59.3%) had an unhealthy diet. Males scored significantly higher in somatic complaints, anxiety, depression, and aggression (<i>p</i> < 0.05). Urban adolescents showed higher mania and dominance, while rural counterparts reported higher suicidal ideation and substance problems (<i>p</i> < 0.05). Notably, normal-weight adolescents exhibited higher antisocial traits than those with excess weight (<i>p</i> < 0.05). Correlation analyses revealed significant negative associations between diet quality and depression, antisocial traits, aggression, and suicidal ideation. Specifically, diet quality was negatively correlated with suicidal ideation in the clinical group, and with somatic complaints and aggression in the control group (<i>p</i> < 0.05).

Domain-specific analyses indicated that women's financial autonomy, work-life balance, and group membership were associated with improved child nutritional outcomes, while associations with stunting and underweight were less consistent.
