Although some health behavioral problems can decline with age — such as alcohol problems and antisocial behaviors — the risk of depression among women at risk for substance abuse and associated disorders increases.
A longitudinal analysis led by University of Michigan Health System researchers examined the influences of the women’s histories, family life and neighborhood instability on their alcoholism symptoms, antisocial behavior and depression.
The investigation covered a 12-year period including the earlier years of marriage and motherhood.
The research, published in Development and Psychopathology, is part of an ongoing project focusing on families at high risk for substance abuse and associated disorders that has already collected more than 20 years’ worth of data.
Among the study’s other top findings:
“Our findings demonstrate the complexity of the factors affecting changes in alcohol problems, antisocial behavior and depression for these women,” said the study’s senior author, Robert Zucker, Ph.D.
The findings challenge common notions that depression, alcoholism and antisocial behavior, are either just genetic disorders, or alternatively, that they are caused by environmental factors, Zucker said.
“It’s really the network of these relationships — at the biological, social and at the community level — that influences these disorders over time,” he said.
The research also shows that unlike alcoholism symptoms and antisocial behavior, depression does not, by itself, moderate over time – it actually gets worse, at least in this high-risk population, Zucker noted.
“Unlike the other two disorders, biological differences appear to be more of a constant factor in depression,” he said.
The research sample included 273 adult women and their families from communities in the Midwest.
Drunk driving convictions involving the father were used to find the highest risk portion of the sample; a blood alcohol content of .15 was required to help ensure that the men had longstanding difficulties with alcohol abuse, rather than just having been out drinking heavily for one night. The remaining families were recruited from the neighborhoods where the drunk drivers lived.
The findings also underscore the relationship between alcohol abuse and antisocial behavior over long periods of time, said study lead author Anne Buu, Ph.D.
As a result, she said, interventions targeting antisocial behavior could benefit by also systematically targeting addiction.
“Based on these findings, interventions for women with young children might have the most impact if they improve social supports, educational opportunities, access to family counseling and neighborhood environments,” Buu said.
