Visual impairment, but not hearing impairment, is independently associated with lower subjective well being among individuals over 95 years of age: A population based study.
BACKGROUND Sensory impairment affects an increasing number of elderly adults, with a negative psychological impact. Our objective was to examine the associations of visual and hearing impairment with subjective well being (SWB) an important psychological concept defined by life satisfaction [LS] positive affect [PA] negative affect [NA] and affect balance [AB] among long lived individuals (LLIs) over 95 years of age. METHODS Data on 442 LLIs from the Rugao longevity cohort, a population based study in Rugao, China, were analyzed. Graded classifications of visual and hearing impairment (none, mild, moderate, and severe) were constructed from self reported items. Bivariate correlation and multiple regression analysis were performed to test the associations. RESULTS Approximately 66.1% and 87.3% of the subjects reported varying degrees of visual and hearing impairment. Following the degree of vision impairment, LS, PA, and AB decreased linearly, whereas NA increased linearly (all p for trend<0.05) Vision was significantly related to LS (r=0.238, p<0.001) PA (r=0.142, p<0.01) NA (r= 0.157, p<0.001) and AB (r=0.206, p<0.001) After adjustment for multiple variables including functional ability, an important factor of SWB, the associations of vision impairment with LS, NA, and AB, while diminished, still existed. CONCLUSIONS Visual impairment, but not hearing impairment, was independently associated with low SWB among LLIs, and functional ability may play a mediating role in the observed relationship. The findings indicate that rehabilitation targeted for those with reduced vision and functioning in long lived populations may be important for promoting well being and quality of life.
