Alcohol consumption and risk of unemployment, sickness absence and disability pension in Denmark: a prospective cohort study.

AIMS

We investigated the association between weekly alcohol consumption and binge drinking and the risk of unemployment, sickness absence and disability pension.

DESIGN

Prospective register-based cohort study.

SETTING

Denmark.

PARTICIPANTS

A sample of 17 690 men and women, aged 18-60 years from the Danish Health and Morbidity Survey in 2000, 2005 and 2010 participated in the study. Participants worked the entire year prior to baseline.

MEASUREMENTS

Administrative registers were used to obtain information on unemployment, sickness absence and disability pension during a 5-year follow-up period. Data were analysed by multivariate Cox regression model with random effect (frailty) adjusted for cohabitation status, educational level, Charlson comorbidity index, smoking habits, calendar year and geographic region.

FINDINGS

Among males, adjusted hazards ratios (HR) of unemployment were 1.24 (95% CI 1.05-1.46, P = 0.01), 1.28 (95% CI 1.04-1.59, P =0.02) and 1.48 (95% CI 1.21-1.81, P = 0.00) respectively, for abstainers and those with alcohol consumption of 21-27 and ≥ 28 drinks per week when compared with individuals who had 1-13 drinks per week. Corresponding HRs for sickness absence were 1.16 (95% CI 1.02-1.33, P = 0.03), 1.02 (95% CI 0.85-1.23, P = 0.84), and 1.23 (95 % CI 1.04-1.46, P = 0.02). Male abstainers had increased HR for subsequently receiving disability pension. Female abstainers had increased HR of unemployment, sickness absence and disability pension compared to women with moderate alcohol consumption. Binge drinking was associated with higher HR of unemployment compared to non-binge drinking in women: HR of 1.21 (95 % CI 1.03-1.41, P = 0.02).

CONCLUSIONS

In Danish men aged 18-60, alcohol abstinence and heavy consumption is associated with increased subsequent risk of unemployment and sickness absence compared with low consumption. In Danish women abstainers have increased risk of unemployment, sickness absence and disability pension, while binge drinkers are more likely to become unemployed subsequently.
