Abstract
Background: Low levels of social support are known to be linked to decreased cognitive function and increased dementia risks. This study examined how tangible social support provided by offspring to their parents reduces cognitive decline among the elderly.
Methods: This study used data from the Korean Longitudinal Study of Aging. The study subjects were 1,540 individuals aged 65 years and older population who evidenced no cognitive impairment (Korean-Mini Mental State Examination ≥24). They were interviewed in 2006, and then were followed up with for 2 years. Tangible social support (monetary or other) was categorized as giver (and/or taker), only taker, or neither. A multiple logistic regression analysis was conducted to determine the relationships between tangible social support and cognitive decline.
Results: After adjusting for potential confounders, the neither and only taker groups were likely to undergo cognitive decline compared to those in the monetary give-and-take group (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.36–3.60; OR, 1.67; 95% CI, 1.07–2.68, respectively). Among those of the lowest socioeconomic status, the neither group demonstrated more cognitive decline than did the monetary give-and-take group (OR, 4.78; 95% CI, 1.39–22.36).
Conclusion: Encouraging give-and-take between parents and their offspring may assist in protecting the elderly from cognitive decline.
