This purpose of this was to identify the factors associated with cognitive function decline according to gender in Korean elderly.
This study was conducted with a secondary data analysis that used data from the 2017 National Survey on Elderly Status. The participants were 9,862 elderly. Data were analyzed using SPSS Statistics 23.0 to obtain descriptive statistics, cross-analysis (Rao-Scott χ2 test), complex sample t-test, and binary logistic regression analysis. The average score of cognitive function was lower in female elderly (24.50 ± 0.06) than male elderly (26.19 ± 0.06) (p < .001). But, the rate of cognitive decline was higher in male elderly (15.8%) than female elderly (12.6%) (p < .001). The common factors associated with cognitive function decline of the male and female elderly were high-risk nutritional status, hearing discomfort, stroke, lower extremity muscular strength, psychologically dependent object, and employment. Including these common factors, myocardial infarction in male elderly, and education level, moderate-risk nutritional status, frequency of interaction with friends, neighbors, and acquaintances, hyperlipidemia, living alone, and mobility in female elderly were found to be factors associated with cognitive function decline. In order to assess changes in the elderly's cognitive function and develop and apply a nursing intervention program to improve cognitive function, an approach that considers multidimensional factors associated with cognitive function decline according to gender is necessary. In particular, the cognitive function of elderly women is associated with various factors than men, therefore research to find differentiated strategies suitable for female characteristics should be conducted.
