Introduction. The modern lifestyle of girls, including behavioral patterns, social practices and value orientations, has a significant impact on their physical and psycho-emotional well-being. With the increasing prevalence of unhealthy habits in this group, the study of the relationship between lifestyle and subjective assessment of health is becoming particularly relevant. Objective. To identify patterns of association between behavioral lifestyle factors (physical activity, nutrition, smoking, alcohol consumption) and subjective health assessment among youth. Methods. A cross-sectional online survey was conducted among 214 females aged 18—22 years (Me [Q1; Q3] = 20 [19; 21]) using a combined questionnaire that included sections on self-rated health, physical activity, dietary habits, and harmful behaviors. Statistical analysis involved calculation of relative measures, Pearson's χ² test, and correlation analysis. Results. Age-related dynamics were revealed: positive health assessments decreased with age (r = −0.23). Regular physical activity was associated with higher self-rated health (r = 0.45). Balanced nutrition correlated with improved subjective assessment (r = 0.38), while smoking (r = −0.52) and alcohol consumption (r = −0.39) showed inverse relationships. Conclusion. The results confirm the significant influence of a healthy lifestyle on the subjective perception of health in girls. The formation of programs aimed at increasing physical activity, rationalizing nutrition and giving up bad habits can help improve both objective and subjective health in this group.
