A new study has found that lower IQ is associated with greater and riskier drinking among young adult men. Several studies have shown an association between intelligence and various health-related outcomes, the research on cognitive abilities and alcohol-related problems has been inconsistent. Sara Sjolund, a doctoral student at the Karolinska Institutet in Stockholm, Sweden and her colleagues analysed data collected from 49,321 Swedish males born during 1949 to 1951 and who were conscripted for Swedish military service from 1969 to 1971. IQ results were available from tests performed at conscription, and questionnaires also given at conscription provided data on total alcohol intake (consumed grams of alcohol/week) and pattern of drinking, as well as medical, childhood and adolescent conditions, and tobacco use.
"We found that lower results on IQ tests in Swedish adolescent men are associated with higher consumption of alcohol, measured in both terms of total intake and binge drinking," said Sjolund. "It may be that a higher IQ results in healthier lifestyle choices. Suggested explanations for the association between IQ and different health outcomes, could be childhood conditions, which could influence both IQ and health, or that a socio-economic position as an adult mediates the association," said Sjolund. "In reality, other differences of importance are likely to exist among the men, which could further explain the IQ-alcohol association," Falkstedt said.
Drinking alcohol is considered by different studies in different contest. Some studies tell it is good for health if consumed moderately, while some tells that it is harmful to brain which effects the IQ of the person.
