Purpose The purpose of this study was to examine changes in the self-rated health of adolescents and to identify its predictors using longitudinal data from the KCYPS.
Methods A sample of 2,351 adolescents who were in the first grade of middle school in 2010 was analyzed. The study employed latent growth analysis using data from 2010 to 2016.
Results Results indicated that self-rated health of adolescents increased, following the form of a linear function. The analyses revealed that adolescent self-perception of health were conceptualized not only by their health-related behaviors, but also by personal, socioeconomic and psychological factors. Specifically, physical activity, passive leisure time activities, gender (initial: b=-.060, slope: b=.030), place of residence (initial: b=-.079), self-rated economic condition (b=.098), working status of mother (b=.016), monthly family income (b=-.001), aggression (b=.061), depression (initial: b=-.104, slope: b=.012), stress (initial: b=-.172, slope: b=.014, ego-resiliency (initial: b=.197, slope: b=-.021), and self-esteem (initial: b=.106, slope: b=-.017) had significant effects on the overall linear change of self-rated health (p<.05 for all estimators above).
Conclusion The findings of this study suggest that adolescents’ self evaluation of their health is shaped by their total sense of functioning, which includes individual, health-related behavioral, socioeconomic, and psychological factors.
