[Trajectories of Self-rated Health in Secondary Education: Results from the German National Educational Panel Study].

AIM OF THE STUDY
Self-rated health is an important indicator of current and future health. However, panel data-based findings are lacking that take into consideration the background features of differentiated development of self-reported adolescent health. This paper examines the development of self- rated health through secondary education from grade 5-12 in Germany, analyzing differences according to indicators of socio-economic position and other background characteristics such as gender and family structure.


METHODOLOGY
5th to 10th grade data from the "Class 5" cohort and 9th to 12th grade data from the "9th grade" cohort of the National Education Panel were combined. Growth curve models based on multi-level analysis were used to examine the level and course of self-rated health and to examine differences according to type of school, parenting, household income, gender and family structure. The final model contains 28,987 observations from 11,290 individuals over 8 time points.


RESULTS
Self-reported health declines slightly from 5th to 12th grade. Adolescents attending high school, living in higher-income households or parents with higher education status reported better health. Boys and adolescents growing up in nuclear families showed a more favorable course of self-rated health through secondary education.


CONCLUSION
This study provides a comprehensive overview of the development of self-rated health of adolescents in secondary education. In addition to the static differences according to background characteristics, girls and adolescents who do not live in nuclear families also had a worse prognosis for the development of self-rated health over the school career.
