Alcoholics with depression less likely to stay sober

At the beginning of the study, participants smoked at least five cigarettes a day and were alcohol dependent. Among the group, typical problematic drinking symptoms included repeatedly imbibing more than planned, difficulty quitting or cutting down, and continuing to drink even though drinking caused problems such as hangovers or sleeping difficulty.

All participants received intensive alcohol and smoking cessation treatment. Up to a year and a half later, researchers surveyed the participants and asked about their alcohol and tobacco habits.

“Among those who were depressed, the odds of drinking, the next time you checked in with them six months later, were 1.5 times greater than the odds of drinking for individuals without significant depressive symptoms,” said lead study author Molly Kodl.

Of the people who were depressed, the majority suffered only mild to moderate mood problems.

“With significant depression, people report mood that is down in the dumps, loss of interest in things they used to enjoy, low energy, appetite changes and difficulty concentrating,” Kodl said.

While depression seems to lessen the chances of alcohol abstinence, the study did not find a similar association for tobacco dependence.

“Depression did not significantly impact the odds of succeeding in quitting smoking in this study,” Kodl said.

Substance abuse researcher Robert West says many people do not receive an initial assessment for depression when they join a treatment program.

“It depends very much on the program,” said West, professor of health psychology at the Cancer Research UK Health Behaviour Unit at the University College London.

Nevertheless, Kodl said: “Our study suggests that treating depression may help people recover from alcohol use problems, although more research is needed on this topic.”
