Background: As the elderly population increases in number, prediction and prevention of functional decline in this population are of great importance. This study evaluated whether depression in an elderly population could predict functional decline in activities of daily living and the components of instrumental activities of daily living 2 years after baseline. Methods: Data from the Korean Longitudinal Study of Aging panel, a national, representative sample of aging Koreans, were used. The subjects were the elderly aged 65 years or older who had no disabilities that hindered them from performing activities of daily living at baseline. Depression was measured using the Short-form (10-item) Center for Epidemiological Studies Depression Scale. Multivariable logistic regression analysis was performed to evaluate the effect of functional impairment according to baseline depression. Results: Of the 3,477 participants, 166 (4.8%) showed at least 1 impairment in the 7 activities of daily living (ADL) categories after 2 years. The participants with depression (scored 15 or higher on the depression scale) were more likely to have functional decline 2 years later (odds ratio, 1.82; 95% confidence interval, 1.23-2.71). All the components of the ADL had an increased tendency to develop functional decline (all odds ratios>1.00). Furthermore, negative items were significantly associated with functional decline (all p-values adjusted for trend<0.05). Conclusion: The participants with depression were more likely to have functional decline 2 years later. Such decline was observed in all types of ADL. Therefore, depression should be monitored and used as a predictor of functional decline in elderly adults.

“…Furthermore, emotional conditions, including depression, might play an important role in functional decline 11) . However, most studies focused on the relationship between symptoms of depression and functional decline were cross-sectional and thus could not ascertain causal relationships [12][13][14] .…”

“…This is in agreement with the study result in which researchers demonstrated the independent association of positive affect in lowering the risk of functional decline. [17] Several explanations have been proposed for the mechanisms underlying the link between positive affect and cognitive health. For example, favorable health behaviors such as not smoking are more prevalent among happier people.…”

“…Recent studies have used GDS in this manner to assess the predictive power of positive affect on older person's health, such as functional decline or cognitive impairment. [17,23] The five GDS items for measuring positive affect are "feeling satisfied with life," "feeling happy most of the time," "feeling full of energy," "feeling wonderful to be alive," and "being in good spirits most of the time." The answer was dichotomized as yes/no.…”

“…For example, Hirosaki et al demonstrated the effect of positive affect against functional decline. [17] Using data from the North Carolina EPESE study, Ostir et al demonstrated that stroke incidence is lower for individuals with a high positive affect score. [18] However, as far as we know, no studies have investigated the association between positive affect and incident dementia.…”

Background: We investigated the association between positive affect and incident dementia among the old. Studies have reported the role positive affect has on maintaining health. Still, no longitudinal studies have assessed the association between positive affect and incident dementia. Methods: We used the Aichi Gerontological Evaluation Study (AGES) data. Participants were older adults (65 +) who did not receive benefits from Japan's public Long-Term Care Insurance System at baseline (N = 14,286) in 6 municipalities. They were followed from 2003 to 2007 for dementia onset. Dementia onset was determined according to the criteria used in the Long-Term Care Insurance System. Positive affect was assessed by sub-scales of the Geriatric Depression Scale (GDS-15). Cox hazard proportional models stratified by sex were employed to calculate hazard ratios for incident dementia. Results: Of 14,286 participants (6,813 men and 7,473 women), 333 men (4.9%) and 468 women (6.3%) developed dementia during the 4 year follow-up. In age adjusted Cox models, positive affect was significantly associated with lower risk of dementia both among men and women. Even after adjusting for health status, health behaviors, social engagement, and low education, positive affect persisted as a significant protector against dementia. Conclusions: We observed a protective role of positive affect against cognitive decline. Factors associated with higher positive affect scores were healthier life style, social engagement, and physical health. This implies the importance of maintaining such activities to promote cognitive health among the old. In doing so, the role of positive affect merits attention.

Positive affect as a predictor of lower risk of functional decline in community‐dwelling elderly in Japan

Abstract: Positive psychological well-being, specifically the feeling of satisfaction with life, happiness and energy, might have a favorable effect on the maintenance of functional ability, regardless of negative affect.
