Depression, distress and their association with patterns of psychoactive substance use during the COVID-19 emergency state in latvia

INTRODUCTION: The WHO warned that the COVID-19 pandemic could have psychiatric consequences such as elevated levels depression, increased alcohol and drug use, and other behaviours that exert a strong influence on health. In Latvia a state of emergency was announced on March 12(th), was extended twice and lifted on June 10th. OBJECTIVES: To estimate the prevalence of depression and distress in the general population of Latvia and association with substance use during the state of emergency. METHODS: The nationwide representative online study in the general population of Latvia was conducted in July 2020 during three week period. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to determine the presence of distress/depression. The structured questionnaire to determine psychoactive substance use was applied. Proportions of independent variables across the study groups were compared using Chi-square test. RESULTS: The study sample included 2608 respondents. The prevalence of depression and distress was estimated at 5.7% (95%CI 4.92 – 6.71) and 13.5% (95%CI 6.85 – 8.91), respectively. Patients with depression (28% vs. 7.4%, p <0.001) and distress (30.9% vs. 7.4% p <0.05) smoked more tobacco compared to respondents without distress/depression. Those with depression or distress were significantly more likely to consume more alcohol during the emergency state than people without depression or distress (14.0% and 17.7% vs. 6.6%, p <0.001). The changes in the use of other psychoactive substances in those who had depression or distress were not statistically significant. CONCLUSIONS: Preparing support systems to mitigate mental health consequences is needed urgently.
