Longitudinal studies on how temperament is related to alcohol use in general population are scarce.

Finding relations with temperament and problematic alcohol use using prospective birth cohort data.

To investigate trends in self-reported alcohol consumption in adulthood.

In the Northern Finland Birth Cohort 1966 (n = 5247), alcohol use was studied with questionnaires at ages 31 and 46. Participants were classified into abstainers, bingers, heavy drinkers, steady drinkers, increasers or reducers based on the change in consumption (g/day). Cloninger's TCI-scores were calculated for each group. Multinomial regression analysis was conducted with TCI-scores as factors influencing the change in alcohol consumption.

High novelty seeking was associated with increased consumption, binging and heavy drinking among both sexes at both time points (P < 0.01). Lower persistence was associated with increased consumption at both time points among men and among women at age 46. Baseline novelty seeking predicted both increasing (OR 1.1; 95% CI: 1.0–1.1) and reducing (1.1; 1.0–1.1) for men and for women also increasing (1.1; 1.0–1.1) and reducing (1.1; 1.0–1.1), but when adjusted with baseline alcohol use novelty seeking only predicted increasing for men (1.0; 1.0–1.1).

High novelty seeking and low persistence are associated with problematic alcohol use among middle-aged Northern Finns. Gender differences in predictors existed: novelty seeking predicted increase only for men in the adjusted model. Temperament scores do not seem to affect strongly changes in alcohol use.
