Survey on Mental Health Status in Iranian Population Aged 15 and Above One Year after the Outbreak of COVID-19 Disease: A Population-Based Study

Mental disorders are the most common health problems that affect different population groups. According to the national survey in 2015 based on General Health Questionnaire-28 (GHQ-28), 23.44% of Iranians older than 15 years were suspected of having a mental disorder. The study aimed to determine the mental health status of the population over 15 years of age in the Islamic Republic of Iran, one year after the outbreak of COVID-19 in 2020.

The population-based study was performed on 24584 individuals over 15 years of age in Iran between December and February, 2020. The GHQ-28 was completed through telephone interviews. Data were analyzed using descriptive statistics, chi-square test, independent t-test, and multiple logistic regression at 95% confidence level.

The results showed that the mean age of participants was 44.18±16.47 years. The prevalence of mental disorders was 29.7%. Mental disorder was associated with female gender (OR=1.195, 95% CI 1.10–1.29), 25–44 years (OR=1.206, 95% CI 1.06–1.36), urban life (OR=1.116, 95% CI 1.04–1.19), illiteracy (OR=1.286, 95% CI 1.11–1.48), being divorced (OR=1.924, 95% CI 1.50– 2.45), and unemployment (OR=1.657, 95% CI 1.40–1.94). Among the participants and their families, 14.7% and 32.3% were infected with the disease, respectively. The COVID-19 mortality rate in their families was 13.2%. The prevalence of mental disorders in infected people (40% vs. 27.3%) and bereaved families (39.6% vs. 35.3%) was more than the non-infected groups.

Our results showed that in Iran, the mental health of the general population had a rising trend compared to 2015, especially in people infected with COVID-19 and bereaved families. The observed difference may be due to the prevalence of the COVID-19 epidemic and rapid demographic, social, and economic changes in Iran. Planning to improve mental health in the mentioned population should be considered for the post COVID-19 era.
