PurposeTo compare the associations of alcohol-related variables with Quality of Life (QoL) in depressed and non-depressed individuals of the general population.MethodsThis cross-sectional study utilized data from the FINRISK 2007 general population survey. A subsample (n = 4020) was invited to participate in an interview concerning alcohol use. Of them, 2215 (1028 men, 1187 women; response rate 55.1%) were included in the analyses. Bivariate associations between mean weekly alcohol consumption, frequency of binge drinking, Alcohol Use Disorders Identification Test (AUDIT)-score and QoL were analysed according to categorization into depressed and non-depressed using the Beck Depression Inventory, Short Form. Linear regression models were calculated in order to determine the associations of the alcohol variables and QoL after adjusting for socio-demographic variables as well as somatic and mental illness.ResultsDepressed individuals had lower mean QoL and higher AUDIT-scores than non-depressed respondents. Bivariate correlations showed that mean weekly alcohol consumption, frequency of binge drinking and AUDIT-scores were statistically significantly associated with impaired QoL in depressed individuals. Abstinence was not associated with QoL. After adjustment for covariates, frequency of binge drinking and AUDIT-score were statistically significantly associated with QoL in depressed individuals and AUDIT-score in the non-depressed group. When analysing all respondents regardless of depression, both AUDIT-score and binge drinking were associated with QoL.ConclusionsOf the alcohol-related variables, binge drinking and alcohol problems indicated by AUDIT-score contributed to impaired QoL in depressed individuals and both should be assessed as part of the clinical management of depression.
