Student Characteristics and Behaviours in Childhood Predict Self-reported Health in Middle Adulthood

We examined how self-reported and teacher-rated student characteristics in primary school were associated with adult self-reported health. A representative sample of Luxembourgish students was assessed in 1968 (M-age = 11.9, SD = 0.6) and 2008 (N = 745; M-age = 51.8, SD = 0.6). Self-reported sense of inferiority and pessimism in childhood were negatively related to subjective health and vitality-related quality of life/health in adulthood (rs = -.08 to -.12); teacher-rated studiousness (age 12 years) was positively related to subjective health, healthcare utilization and vitality-related quality of life/health (age 52 years; rs =. 13 to .16). After controlling for childhood IQ, parental socio-economic status, educational attainment and sex in multiple regression analyses, most effects of teacher-rated studiousness showed incremental validity beyond the controls. School entitlement, sense of inferiority, impatience and pessimism were positively related to body mass index (rs = .08 to .13). The responsible student scale and teacher-rated studiousness were negatively related to body mass index (rs = -.09 to -.13). The findings demonstrate that childhood characteristics and behaviours are important life-course predictors of key health dimensions beyond childhood IQ and parental socio-economic status. In addition, this narrower level of assessment adds significantly to the empirical body of knowledge on long-term predictors of health outcomes in adulthood.
