Co-morbid health conditions at mid-life in the Iowa adoptees.
Adverse health effects due to alcohol and illicit drug abuse and dependence have been well documented. This study examines the effect of substance misuse on five major groups of health conditions using a sample of well characterized adoptees. The sample consisted of 742 adoptees interviewed in the last wave of the Iowa Adoption Studies. Death rate analyses included an additional 34 participants who had died prior to the last follow-up. Substance use patterns and medical history were assessed using the SSAGA-II (Bucholz, K. K., Cadoret, R. J., Cloninger, C. R., Dinwiddie, S. H., Hesselbrock, V. M., Nurnberger, J. L., Jr., et al. (1994). A new, semi-structured psychiatric interview for use in genetic linkage studies: a report on the reliability of the SSAGA. Journal of Studies on Alcohol, 55 (2), 149-158). Subjects were divided into three groups according to DSM-IV diagnostic criteria, controls, alcohol abuse or dependence only (alcohol only), and the Alcohol-Drug group (abuse or dependence diagnosis on at least one illicit substance with or without alcohol diagnosis). Incidence rates of various diseases were measured using logistic regression. Survival analyses were used to examine whether substance abusers developed cardiovascular or metabolic disease at an earlier age than control subjects. Diagnostic grouping made no difference in the incidence rates or age of onset of health conditions. The amount of alcohol consumed by males significantly predicted higher number of overall health complaints as well as higher incidence rates of cardiovascular disease. The amount of illicit drug exposure did not predict an earlier age of diagnosis for cardiovascular or metabolic disease. Individuals in the Alcohol-Drug group had an increased incidence of deaths than either the alconly or the control groups.
