RESUMO
OBJECTIVE: We examined the role of gender, family, lifestyle and psychological factors in self-rated health. DESIGN: Cross-sectional study. SETTING: A total of 970 randomly selected students from 11 secondary schools in Lima and Callao, Peru, participated in 2014. MAIN OUTCOME MEASURE: Self-rated health was measured with a single item: 'In general, how would you rate your health?' Responses were arranged along a five-point Likert-type scale: 'excellent', 'very good', 'good', 'fair' and 'poor'. The outcome variable was dichotomised as 'good' (excellent, very good or good) or 'poor/fair' (poor or fair). METHODS: We calculated adjusted ORs (AORs) and 95% CIs for poor/fair self-rated health using multivariate logistic regression analyses at 3-graded levels. RESULTS: 32.5% of the respondents had fair/poor self-rated health, 23.7% of the total males and 40.0% of the total female samples. Males were less likely to have poor/fair self-rated health (AOR 0.61; CI 0.41 to 0.91). Poor family support strongly increased the likelihood of having poor/fair self-rated health (no support, (AOR 3.15; CI 1.63 to 6.09); low support, (AOR 2.50; CI 1.29 to 4.85)). The other associated variables were missed meals due to a shortage of food (AOR 1.97; CI 1.15 to 3.36), television watching during leisure time (AOR 1.70; CI 1.09 to 2.67), low physical activity (AOR 1.49; CI 1.03 to 2.15), school absenteeism (AOR 1.54; CI 1.03 to 2.31) and perceived life satisfaction (AOR 0.28; CI 0.15 to 0.25). CONCLUSIONS: Gender, missing meals due to a shortage of food, family support, physical activity and life satisfaction influenced self-rated health among adolescents in Peru. Interventions that focus on promoting physical activity for at least 1â h each day for 3 or more days per week, food security and strengthening supportive family roles may improve self-rated health during adolescence.
