OBJECTIVES: To examine the health-related quality of life (HRQoL) among residents in Tianjin, China, by using the EQ-5D-5L and investigate the factors that influence the HRQoL.

METHODS: Data used in this study were obtained from the 2023 National Health Service Survey (NHSS) in Tianjin. Respondents aged ≥15 years were included in this study. In this survey, respondents provided information on their demographic (i.e., gender, age), socioeconomic (i.e., employment status, recipients of medical assistance), health behaviors (i.e., physical activities, medical examinations), and disease-related characteristics (i.e., chronic disease, discomfort in 2 weeks), and completed the EQ-5D-5L through face-to-face interviews. Ordinary least square regression (OLS) model was used to investigate the associate factors of HRQoL of respondents.

RESULTS: A total of 3,744 respondents (48.48% male, mean [SD] age 53.48 [17.20]) were included in this study. The mean (SD) EQ-5D-5L utility value was 0.95 (0.16). Reported problems in mobility accounted for 9.32%, reported problems in self-care accounted for 4.9%, reported problems in usual activity accounted for 7.29%, reported problems in pain/discomfort accounted for 16.4% and reported problems in anxiety/depression accounted for 7.24%. OLS model showed that lower EQ-5D-5L index scores were associated with older age, lower levels of education, unemployment, recipients of medical assistance, diabetes, hypertension, other chronic diseases, accidental injuries, discomforts in 2 weeks and lack of regular physical activities and medical examinations.

CONCLUSIONS: Overall, the Tianjin residents have a good level of HRQoL. Low socioeconomic status, bad health behaviors and various disease and injury situations were associated with poor HRQoL.
