Malnutrition Risk in Community-Dwelling Older Adults with Dual Sensory Declines: Focusing on Social Determinants of Health

Purpose: As the number of older adults with dual sensory declines is increasing, they face a higher risk of malnutrition compared to those without these declines. Although social determinants of health can influence malnutrition, there has been limited research on this population. This study aimed to explore the association between malnutrition risk and social determinants of health among older adults with dual sensory declines. Methods: The study is a cross-sectional analysis using data from the 2020 National Survey of Older Koreans. Binomial logistic regression analysis was conducted to examine the association between malnutrition risk and social determinants of health. These determinants include structural determinants, social capital, and intermediary determinants among older adults with dual sensory declines. Results: 1,771 with dual sensory declines were included in the analysis. Among the structural determinants, women (odds ratio [OR]=1.75, 95% confidential interval [CI] 1.19~2.57) and national basic livelihood security system recipients (OR=1.87, 95% CI 1.13~3.07) were significantly associated with malnutrition risk. In social capital, social non-participation (OR=1.33, 95% CI 1.03~1.73) and social network size (OR=0.95, 95% CI 0.92~0.98), Among intermediary determinants, living dissatisfaction (OR=1.61, 95% CI 1.16~2.23), environmental satisfaction (OR=0.95, 95% CI 0.92~0.99), household debt (OR=1.59, 95% CI 1.02~2.49) and comorbidity (OR=3.85, 95% CI 2.98~4.97) were significantly related to malnutrition risk. Conclusion: These findings highlight the critical need to address key social determinants of health to enhance nutritional outcomes for older adults with dual sensory declines.
