Summary: Self-rated health is an important subjective indicator reflecting individual perception of health status and is influenced by biological, behavioral, and sociocultural factors, especially during adolescence. This study aimed to analyze the association between self-rated health, nutritional status, and physical activity level in adolescent students. This is a cross-sectional study with a quantitative approach conducted with 122 adolescents of both sexes enrolled in a public school. Anthropometric variables, physical activity level, and self-rated health were assessed using standardized instruments. The results showed statistically significant differences between sexes for anthropometric variables, with higher values observed in boys for body weight (72.48 ± 17.27 kg vs. 57.07 ± 11.95 kg; p = 0.0002), height (173.7 ± 7.23 cm vs. 165.2 ± 7.13 cm; p < 0.0001), body mass index (24.05 ± 6.02 kg/m2 vs. 20.82 ± 3.81 kg/m2; p = 0.0063), and lean body mass (56.96 ± 7.49 kg vs. 43.54 ± 5.97 kg; p < 0.0001). Regarding physical activity, boys showed higher weekly time in vigorous physical activity (508.0 ± 809.8 min/week) compared to girls (248.6 ± 483.2 min/week; p = 0.037). A significant association was found between nutritional status and self-rated health (p = 0.033), indicating worse health perception among adolescents with nutritional imbalance. In conclusion, nutritional status is associated with self-rated health in adolescents, while sex differences are mainly observed in anthropometric variables and vigorous physical activity, highlighting the multifactorial nature of health perception during adolescence.
