Substance Use and Mental Health during the First COVID-19 Lockdown in Germany: Results of a Cross-Sectional Survey.

BACKGROUND: The measures taken to contain the COVID-19 pandemic have led to significant changes in people's daily lives. This paper examines changes in substance use during the first lockdown (March-July 2020) and investigates mental health burdens in substance users with increased consumption of alcohol, nicotine or tetrahydrocannabinol (THC) in Germany compared to users with unchanged or reduced consumption. METHOD: In a cross-sectional online survey, 2369 people were asked about their mental health and their substance use during the first lockdown in Germany. RESULTS: Of the participants, 28.5% increased their alcohol use, 28.8% their use of tobacco products, and 20.6% their use of THC-containing products during the pandemic. The groups with increased alcohol, nicotine, and THC use during the first lockdown reported more depressive symptoms and anxiety. Individuals who reported increased consumption of alcohol or nicotine were also more likely to experience loneliness and have suicidal thoughts and were more often stressed due to social distancing. CONCLUSION: Alcohol, nicotine and THC increased in a subgroup of consumers who reported to have more mental health problems compared to individuals who did not increase their consumption. This increased substance use could, therefore, be understood as a dysfunctional strategy to cope with negative emotions during the lockdown.

Mental health of Covid-19 risk groups during the first Covid-19 lockdown in Germany: a cross-sectional study.

BACKGROUND: The ongoing Covid-19 pandemic not only threatens physical health, but also affects the mental health of people. Yet, health consequences of the pandemic do not affect all members of society equally. We therefore assessed the mental health burden of individuals who are at increased risk of severe illness from Covid-19 compared to individuals who are at low risk of severe illness during the first lockdown (March, 2020) in Germany. Furthermore, we investigated variables mediating the effect of being an individual at increased risk of serve illness on depression. METHODS: Adult German residents (n = 2.369) provided responses to a cross-sectional online survey about risk factors for of severe illness from Covid-19 and various aspects of mental health during the first lockdown in Germany. For data collection, standardized and validated self-report measures were used and for data analysis Mann-Whitney U-tests as well as regression and mediation analyses were performed. RESULTS: The results clearly show that the mental health burden is higher among individuals at increased risk of severe illness from Covid-19 compared to individuals at low risk of severe illness from Covid-19. Moreover, our findings indicate that the association between Covid-19 risk status and depressive symptoms is mediated by concerns about mental health, anxiety and loneliness in a causal effect chain. CONCLUSIONS: Individuals at increased risk of severe illness from Covid-19 have an increased need for psychosocial support during times of lockdown. Future public health policies should pay special attention to these individuals and support them by targeted offers. More research, however, is needed on possible long-term consequences of social distancing on mental health.
