ABSTRACT
BACKGROUND:
The established relationship between vision impairment and depression is limited by the examination of depression only as a unidimensional construct. The present study explores the vision-depression relationship using a dimensional approach.METHODS:
9036 participants aged 65 years and above enrolled in the Three-City study were included. Relationships between baseline near Vision Impairment (VI) or self-reported distance Visual Function (VF) loss with trajectory of four dimensions of depression - depressed affect, positive affect, somatic symptoms and interpersonal problems - over 12 years were examined using mixed-effects models. Depression dimensions were determined using the four-factor structure of the Centre for Epidemiology Studies-Depression Scale (CESD).RESULTS:
In the fully adjustment models, mild near VI predicted poorer depressed affect (bâ¯=â¯0.04, pâ¯=â¯.002) and positive affect (bâ¯=â¯-0.06, pâ¯<â¯0.001) over time, with evidence of longer term adjustment. Distance VF loss was associated with poorer depressed affect (bâ¯=â¯0.27, pâ¯≤â¯.001), positive affect (bâ¯=â¯-0.15, pâ¯=â¯.002), and somatic symptoms (bâ¯=â¯0.18, pâ¯≤â¯.001) at baseline, although only the association with depressed affect was significant longitudinally (bâ¯=â¯0.01, pâ¯=â¯.001). Neither near VI nor distance VF loss was associated with interpersonal problems.LIMITATIONS:
This paper uses a well-supported model of depression dimensions, however, there remains no definite depression dimension model. Distance VF loss was self-reported, which can be influenced by depression symptoms.CONCLUSIONS:
Vision impairment in older adults is primarily associated with affective dimensions of depression. A reduction in social connectedness and ability to engage in pleasurable activities may underlie the depression-vision relationship. Older adults with vision impairment may benefit from targeted treatment of affective symptoms, and pleasant event scheduling.Palavras-chave
