| Annotation | Genetically informative longitudinal data on self-reported symptoms of depression allow for an investigation of the causes of stability and change in depression symptoms throughout adult life. The authors investigate the relative contribution of genetic and environmental influences to symptoms of depression in 83 monozygotic and 84 dizygotic twin pairs from the US National Heart, Lung and Blood Institute (NHBLI) Twin Study. Participants first completed the Center for Epidemiologic Studies - Depression (CES-D) scale in 1985/86 and again during 1995/97. Mean age of twins at baseline was 63, range 59 to 70. From cross-sectional genetic analyses, the authors estimated the heritability of CES-D to be 25% at baseline and 55% at follow-up. Fitting longitudinal genetic models to the two-wave data, the stability of symptoms over the 10-year follow-up was found due primarily to continuity of genetic influence. (RH). |
