Abstract:
Objective:To investigate the association between different socioeconomic status (SES) levels and the incidence of sensory impairment (SI) in the Chinese population.Methods:This study adopted a prospective cohort design, utilizing data from the China Health and Retirement Longitudinal Study (CHARLS) collected in July or August 2011. Participants who met the inclusion and exclusion criteria were followed up every 2-3 years until the onset of SI or the end of the follow-up period (August 2018). Based on educational attainment and annual per capita household expenditure, participants were classified into four SES groups: low, lower-middle, upper-middle, and high SES. Logistic regression was employed to analyze the relationship between different SES levels and the incidence of SI.Results:A total of 7 415 participants were included in the study, with a mean follow-up duration of 4.9 years. A total of 3 644 cases of incident SI were recorded (49.1%). Compared with the high SES group, the risk of developing SI was progressively higher in the upper-middle SES group ( OR=1.42, 95% CI: 1.03-1.96), lower-middle SES group ( OR=1.83, 95% CI: 1.29-2.60), and low SES group ( OR=2.04, 95% CI: 1.42-2.94) ( P for trend<0.001). Conclusions:SES is closely associated with new-onset SI. Enhancing SES may help reduce the risk of developing SI.
