Abstract
ObjectiveTo investigate whether parental social class and cognitive ability in childhood, as well as social and psychological factors, particularly personality traits, are independently associated with binge drinking in 50 year old adults assessed in a longitudinal birth cohort study.Method17,415 babies born in Great Britain in 1958 and followed up at 11, 33, and 50 years of age. Their binge drinking alcohol abuse at aged 50 was the outcome measure.Results6,478 participants with data on parental social class, childhood cognitive ability, educational qualifications at age 33, personality traits, psychological distress, occupational levels, and alcohol consumption (all measured at age 50) were included in the study. Using logistic regression analyses, results showed that parental social class, childhood intelligence, educational qualifications, occupational levels, personality traits (Extraversion and Disagreeableness), as well as psychological distress, were all significantly and independently associated with adult excessive alcohol use. Men tended to binge drink more than women (22% in men and 9.8% in women).ConclusionBoth social and psychological factors influence adult excessive alcohol consumption. Personality traits play a more important role than previously understood. There appears to be a distinction between the frequency and dose level of alcohol consumption.

Summary
The prevalence of alcohol misuse has increasingly become one of salient social concern. It affects individuals’ daily functioning and health [1], and has costly social and societal consequences. Parental social class, education, and occupational levels are found to be related to alcohol use and misuse [2]. There is evidence that childhood cognitive ability is positively related to a higher average intake of alcohol and to drinking more frequently [5,6,7], yet various studies have shown that intelligence measured in childhood has a positive association with health and mortality [8,9,10,11]. It is plausible though to assume that people with higher intelligence are less likely to engage in hazardous behaviours, such as binge drinking, which may potentially impair one’s mental and physical health [1,3]
