Socio-Economic Inequality and Mental Health in Tehran, Iran

  Background and Objectives: Understanding and analyzing the socio-economic factors affecting mental health is important for mental health policy-making in metropolitan areas. The aim of this study was to investigate the relationship between socio-economic factors and mental health of households living in Tehran.   Methods: This cross-sectional descriptive-analytical study was conducted on 650 households from 22 districts of Tehran using mixed sampling method. Mental health measures were collected using the standard SF-36 questionnaire and socioeconomic measures of the household were collected using a researcher-made questionnaire. The face validity of the questionnaire was measured by qualitative method and its content validity was confirmed by quantitative method. The test-retest method was used to test the questionnaire reliability. Regression models were estimated using ordinary least squares (OLS) and weighted least squares (WLS) methods. The Stata software was used for data analysis.   Results: Among the socioeconomic variables, four variables including years of education, health behaviors (regular physical activity, healthy eating habits), not-smoking, and social capital had a positive and significant relationship with all mental health measures (social role, emotional role, mental health and vitality ). The relationship between not-smoking and all mental health measures was more than other socioeconomic variables (P <0.05).   Conclusion: Mental health policymakers should place extra emphasis on the development of social capital in metropolitan cities, promotion of the citizens' health behaviors, and particularly on tobacco use and the related behavioral disorders.
