Background

Health is one of the most important factors that affect happiness. This study aimed to assess the association between happiness and self-rated health among the Iranian adult population.

Methods

This cross-sectional study was conducted on a sample of adults aged 18–65 In Iran in 2020. Demographic information, the Oxford Happiness Questionnaire, and a single item on self-rated health were used to collect the data. The relationship between happiness with demographic variables and self-rated health was examined by performing logistic regression analyses.

Results

In all, 19499 were studied (9845 males and 9654 females). The mean age of participants was 36.38± 8.17 years. The mean happiness score was 4.1± 0.57 (out of 6) and this for self-rated health was 3.66±1.2 (out of 5). The results obtained from logistic regression analysis showed that very poor health status (OR: 5.114, 95% CI, P = 4.490–5.824, p <0.001), poor or very poor income status (OR: 1.553, 95% CI, P = 1.406–1.716, p <0.001), unemployment (OR: 1.704, 95% CI, P = 1.432–2.029, p <0.001), being aged 25–34 years (OR: 1.190, 95% CI, P = 1.088–1.302, p <0.001), and years of education (OR for 10–12 years of education: 1.271, 95% CI = 1.174–1.377, p< 0.001) were significant contributing factors to a lower happiness.

Conclusion

The results showed that self-rated health was the most significant factor that affected happiness even after adjustment for socioeconomic variables, including age, income, employment, and education. Indeed, improving population health might be an effective measure to improve happiness among Iranians.
