Abstract
BACKGROUND: The study aimed to investigate the associations between life and health satisfaction with health-related quality of life (HRQoL), body mass index (BMI) and chronic disease among people who are covered by health insurance schemes in Tehran city, Iran. METHODS: A cross-sectional study was conducted in Tehran city, Iran, from May to June 2016. A total of 600 people were included in the study using a cluster sampling technique. The questionnaire that used for data collection included demographic and socioeconomic variables, questions about health variables such as chronic disease, weight, height, smoking status, and EQ-5D-3L questionnaire. Two univariate and multivariate regression models performed to examine affecting factors on life and health satisfaction. RESULTS: The univariate regression showed that on average female have 0.22 and 0.69 score lower than males with their life and health satisfaction, respectively. Explanatory variables of gender, age, level of education, and employment status were not significantly associated with life and health satisfaction in multiple regression models. However, marital status was correlated with life satisfaction. Furthermore, HRQoL, BMI and chronic disease and smoking were associated with dependent variables (P < 0.001). CONCLUSIONS: The result showed that there was a strong association between BMI, HRQoL, chronic disease, and life and health satisfaction among participants. Therefore, the Iranian policymakers need to consider these factors on life and health satisfaction of adults and design health-promoting programs to improve health outcomes of them. Further studies should assess the associations between BMI, HRQoL, chronic conditions, and life and health satisfaction among Iranian adults.
