BACKGROUND Identifying risk and protective factors for excessive alcohol consumption can inform targeted health policies, reducing the impact of potential mental health crises. This study examined the validity and reliability of COVID-19-related death data and explored the correlations among age, sex, residential status, alcohol abuse, and healthcare access. MATERIAL AND METHODS This analysis of Polish residents' mortality relies on individual data from the register of deaths maintained by Statistics Poland. This study examined deviations in the number of deaths between 2020 and 2021 by analyzing specific causes of death. RESULTS Alcohol abusers had increased COVID-19 risk factors compared to the general population. F10 values were 22% higher than expected in 2020, aligning with predictions for 2021. Higher mortality rates were observed in the first year of the pandemic. In 2020, women and rural residents were more affected (31% and 25% higher than expected, respectively), while men and urban residents were less affected (21% and 20% higher than expected, respectively). In 2021, the trend reversed, with men 2% higher than predicted and women 4% lower. Urban area residents had a 77% lower than expected value, while rural area residents were similar (8% higher). Overall mortality exceeded expectations in both 2020 (13% higher) and 2021 (23% higher). In 2021, alcohol-related non-mental health problems increased by more than 40% in standardized death rates (SDRs). CONCLUSIONS Alcohol-related deaths reflect the hidden effects of the pandemic. Measuring the pandemic's impact on global excess mortality is hindered by inconsistencies in COVID-19 death reporting.
