Aim To assess the association between heavy episodic drinking ( HED ) and deliberate self‐harm ( DSH ) in young people in N orway. Design, setting, participants and measurements We analysed data on past‐year HED and DSH from the second (1994) and third (1999) waves of the Y oung in N orway L ongitudinal S tudy (cumulative response rate: 68.1%, n = 2647). Associations between HED and DSH were obtained as odds ratios and population‐attributable fractions ( PAF ) applying fixed‐effects modelling, which eliminates the effects of time‐invariant confounders. Findings An increase in HED was associated with an increase in risk of DSH ( OR = 1.64, P = 0.013), after controlling for time‐varying confounders. The estimated PAF was 28% from fixed‐effects modelling and 51% from conventional modelling. Conclusion Data on N orwegian youths show a statistically significant association between heavy episodic drinking and deliberate self‐harm.
