| Annotation | In 1963, the self-reported health status was evaluated for 5,229 pairs of twins from the Swedish Twin Registry, and in 1993 for a sub-sample of 351 pairs surviving to age 80. Structural equation modelling evaluated genetic and environmental contributions to total variance and change in variance. For men but not for women, the genetic and environmental influences on health symptoms differed between survivors and non-survivors. Total variance increased, reflecting an increase in environmental variance across the 30 years for both genders. Genetic variance decreased longitudinally for men. The increase in variation from the mid-50s to the mid-80s appears to be due to an accumulation in environmental variation. There are gender differences that deserve further exploration. (RH). |
