Alcohol consumption and associations with sociodemographic and health-related characteristics in Germany: A population survey.

BACKGROUND

To assess the prevalence of ever-drinking and hazardous drinking among adults in Germany, and investigate the factors associated with level of alcohol consumption.

METHODS

Cross-sectional population survey of a representative sample of 11,331 adults in Germany (2018 to 2019). The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) was used to define ever-drinking (AUDIT-C>=1), hazardous drinking (AUDIT-C>=5) and an overall AUDIT-C (alcohol consumption) score (from 0 to 12). Regression models were used to examine sociodemographic and health-related characteristics associated with AUDIT-C score.

RESULTS

The prevalence of ever-drinking and hazardous drinking was 84.7% (95% CI = 84.1-85.4) and 19.4% (95% CI = 18.6-20.1), respectively. The mean AUDIT-C score was 2.8 (SD = 2.16). AUDIT-C scores were independently positively associated with having medium (B = 0.12, 95% CI = 0.02-0.21) and high (B = 0.11, 95% CI = 0.01-0.21) educational qualifications (compared with low), monthly income (B = 0.31 per €1,000, 95% CI = 0.26-0.36), being a current smoker (B = 0.94, 95% CI = 0.86-1.02), anxiety (B = 0.26, 95% CI = 0.02-0.50), and living in North East (B = 0.43, 95% CI = 0.29-0.58), North West (B = 0.47, 95% CI = 0.39-0.55) and South East (B = 0.79, 95% CI = 0.64-0.93) Germany (compared with South West), and negatively associated with age (B = -0.17, 95% CI = -0.21- -0.13), being female (B = -1.21, 95% CI = -1.28- -1.14) and depression (B = -0.22, 95% CI = -0.43- -0.02).

CONCLUSION

In a large, representative sample of adults in Germany, the majority were ever-drinkers and one fifth were hazardous drinkers. Higher alcohol consumption scores were associated with being younger, male, current smoker, of high socioeconomic position, anxiety, and not living in South West Germany, and lower scores were associated with depression. These groups may benefit from targeted alcohol reduction policies and support.
