| Annotation | First, this study uses the ongoing longitudinal Swedish Adoption / Twin Study of Ageing (SATSA) to consider age and cohort explanations for age-related changes in mean values and variance in self-rated health. Second, it evaluates the contributions of genes and environment to self-rated health measured longitudinally. Self-rated health assessments were collected in 4 waves over a 9-year follow-up, from one or both members of 788 twin pairs. Linear mixed effects models were used to test the differences in means and variances. Structural equation modelling provided estimates of genetic and environmental components of variance and contributions to stability. The study finds that both genes and environment contribute to self-rated health longitudinally, and both age and cohort effects are seen. Age-related changes in self-rated health can be attributed to illness. Cohort differences are most likely attributable to socially mediated and individual specific environmental factors. (RH). |
