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.
The most consistent biodemographic correlate of sexual orientation in men is the number of older brothers (fraternal birth order). The mechanism underlying this effect remains unknown. In this article, I provide a direct test pitting prenatal against postnatal (e.g., social/rearing) mechanisms. Four samples of homosexual and heterosexual men (total n = 944), including one sample of men raised in nonbiological and blended families (e.g., raised with half- or step-siblings or as adoptees) were studied. Only biological older brothers, and not any other sibling characteristic, including nonbiological older brothers, predicted men's sexual orientation, regardless of the amount of time reared with these siblings. These results strongly suggest a prenatal origin to the fraternal birth-order effect.
Anaemia was diagnosed in four adopted children during a standard screening examination 1-4 weeks after arrival. Further investigation revealed a number of causes which could then be specifically treated. The children were a girl aged 14 months from China with iron-deficiency anaemia, a boy aged 16 months from Nigeria with sickle cell anaemia, a girl aged 5 from Haiti who had alpha-thalassaemia, and a boy aged 7 from Brazil with spherocytosis. Iron deficiency is the most common cause of anaemia in childhood. However, in adopted children from sub-tropical areas other causes of anaemia like haemoglobinopathies or erythrocyte membrane defects should be borne in mind, particularly as a history of disease and family history are often lacking. Additional investigations may be necessary. An incorrect diagnosis of iron deficiency may result in ongoing and unjustified iron supplementation leading to harmful iron accumulation in thalassaemia and a delay in the correct treatment in sickle cell anemia or spherocytosis which could carry considerable risk.
