Association of changes in self-reported vision and hearing impairments with depressive symptoms in middle-aged and older adults: Evidence from a nationwide longitudinal study in China

Abstract

ObjectiveThis study assessed the longitudinal relationship between changes in self-reported vision impairment (VI) and hearing impairment (HI), and depressive symptoms in adults aged ≥45 years. MethodsData from the China Health and Retirement Longitudinal Study for 2015 and 2018 were used, with a sample size of 10,050. VI and HI were self-reported. The 10-item Center for Epidemiologic Studies Depression Scale (CES-D10) was used to assess depressive symptoms. Total scores and clinically significant depressive symptoms (CES-D10 scores ≥ 10) were used as outcomes and analyzed using generalized estimating equations with identity link and logit link functions. ResultsOf all changes in HI with good vision, only persistent HI was associated with higher CES-D10 scores (OR 95% CI: 1.09–3.30). Both new-onset and persistent VI with good hearing were associated with CES-D10 scores (OR 95% CI, new-onset: 1.70–3.52; persistent: 1.58–2.78) and clinically significant depressive symptoms (OR 95% CI, new-onset: 1.41–2.56; persistent: 1.36–2.27). Persistent dual sensory impairment (DSI) was associated with the highest CES-D10 scores (OR 95% CI: 3.63–5.97) and the highest risk of clinically significant depressive symptoms (OR 95% CI: 1.78–2.85). Those who self-reported improvements in vision and hearing still had higher CES-D10 scores (OR 95% CI: 1.35–2.83) and a higher risk of clinically significant depressive symptoms (OR 95% CI: 1.03–2.02) than those maintaining good vision and hearing. ConclusionSelf-reported VI and DSI are closely associated with depressive symptoms. Because VI and DSI are modifiable, interventions for them could also prevent depressive symptoms.
