IQ and Alcohol Consumption

1 Mar

A paper published in Alcoholism: Clinical and Experimental Research:

Studies of the association between IQ and alcohol consumption have shown conflicting results. The aim of this study was to investigate the association between IQ test results and alcohol consumption, measured as both total alcohol intake and pattern of alcohol use.

The study population consists of 49,321 Swedish males born 1949 to 1951 who were conscripted for Swedish military service 1969 to 1970. IQ test results were available from tests performed at conscription. Questionnaires performed at conscription provided data on total alcohol intake (consumed grams of alcohol/wk) and pattern of drinking. Multinomial and binomial logistic regressions were performed on the cross-sectional data to estimate odds ratios (ORs) with 95% confidence intervals (CIs). Adjustments were made for socioeconomic position as a child, psychiatric symptoms and emotional stability, and father’s alcohol habits.

We found an increased OR of 1.20 (1.17 to 1.23) for every step decrease on the stanine scale to be a high consumer versus a light consumer of alcohol. For binge drinking, an increased OR of 1.09 (95% CI = 1.08 to 1.11) was estimated for every step decrease on the stanine scale. Adjustment for confounders attenuated the associations. Also, IQ in adolescence was found to be inversely associated with moderate/high alcohol consumption measured in middle age.

We found that lower results on IQ tests are associated with higher consumption of alcohol measured in terms of both total alcohol intake and binge drinking in Swedish adolescent men.”

Ironically the account of this study in The Telegraph linked to this story:

Skepticism about twelve step programs

14 Apr

In the most recent issue of Pacific Standard, Maia Szalavitz reviews a number of recent books that critically examine Alcoholics Anonymous, and similar programs:

“some studies find that people mandated into AA do worse than those who are simply left alone. (If true, that would be no small problem. AA’s own surveys suggest that some 165,000 Americans and Canadians annually are court-mandated into the program—despite the fact that every court ruling on the issue has rejected such coercion as unconstitutional, given AA’s religious nature.)

Contrary to popular belief, most people recover from their addictions without any treatment—professional or self-help—regardless of whether the drug involved is alcohol, crack, methamphetamine, heroin, or cigarettes. One of the largest studies of recovery ever conducted found that, of those who had qualified for a diagnosis of alcoholism in the past year, only 25 percent still met the criteria for the disorder a year later. Despite this 75 percent recovery rate, only a quarter had gotten any type of help, including AA, and as many were now drinking in a low-risk manner as were abstinent.”
