Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has found that AD in women is associated with delayed reproduction (see also Alcoholism).
Results will be published in the November issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.
"Reproductive dysfunctions include a range of menstrual disorders, sexual dysfunctions, and pregnancy complications that include spontaneous abortion or miscarriage," explained Mary Waldron, assistant professor of psychiatry at Washington University School of Medicine and corresponding author for the study. "Teenagers who drink tend to have disruptions in their menstrual cycle as well as unplanned pregnancies."
These complications may become more pronounced with time, added Sharon C. Wilsnack, Chester Fritz Distinguished Professor in the department of clinical neuroscience at the University of North Dakota School of Medicine & Health Sciences. "Higher rates of reproductive dysfunction in adult women may reflect the cumulative effects of longer exposure to alcohol for older women than for female adolescents," she said.
For this study, Waldron and her colleagues analyzed data gathered on two groups of Australian twins born between 1893-1964 (3,634 female and 1,880 male twins) and 1964-1971 (3,381 female and 2,748 male twins). Control variables included socio-demographic characteristics, regular smoking, history of psychopathology, and family and childhood risks.
Results indicate delayed reproductive onset among alcoholic women in both groups, with little to no effect observed among men.
"To our knowledge, this is the first study to examine alcohol's effects on reproductive onset across reproductive development," said Waldron. "Most previous research has examined risks to teens or adults but not both. Our findings highlight a risk associated with ...
