Abstract

This study aims to examine the moderating effect of social support on the relationship between nutritional status and depression in the older adults with cognitive impairment group. For this purpose, 2,545 older adults with cognitive impairment group and 7,281 normal older adults selected based on a cognitive function diagnostic test were selected as final analysis subjects among all respondents in the 2020 survey of living conditions and welfare needs of Korean older persons. As a result of the study, it was found that both the nutritional status and depression relationship between cognitive impairment group and normal older adults were negatively significant. It was found that the elderly with cognitive impairment group had a significant the blood relation social support system among social support, and normal older adults had a significant non-blood relation social support system among social support. In other words, the lower the blood relation social support system for the elderly with cognitive impairment group, and the lower the non-blood relation social support system for the normal older adults, the higher the depression. Finally, as a result of examining the moderating effect of social support, it was found that the elderly with reduced cognitive function had a moderating effect in the blood relation social support system and the normal older adults elderly in the non-blood relation social support. Therefore, this study expanded the academic discussion by examining the moderating effect of social support on nutritional status and depression in the elderly based on NSS (New Nutrition Science), which emphasizes theories related to nutrition, depression, and social support. In particular, it is meaningful in that it can be used as basic data for practical and policy measures by conducting research on the elderly with cognitive decline, who have a high prevalence of dementia and mild cognitive impairment.

老年认知障碍患者营养状况与抑郁的关系:基于社会支持的调节作用

本研究旨在探讨社会支持在老年认知障碍患者营养状况与抑郁之间的调节作用。为此，在“2020年韩国老年人生活条件和福利需求调查”的所有调查对象中，选择了2545名认知障碍老年人和7281名通过认知功能诊断测试选出的正常老年人作为最终分析对象。研究结果发现，认知障碍组与正常老年人的营养状况和抑郁关系均呈显著负相关。研究发现，认知障碍老年人在社会支持中具有显著的血缘关系社会支持系统，正常老年人在社会支持中具有显著的非血缘关系社会支持系统。也就是说，认知障碍老年人的血缘关系社会支持系统越低，正常老年人的非血缘关系社会支持系统越低，抑郁程度越高。最后，对社会支持的调节作用进行了检验，发现认知功能下降的老年人在血缘关系社会支持系统中具有调节作用，正常老年人在非血缘关系社会支持系统中具有调节作用。因此，本研究以强调营养、抑郁和社会支持相关理论的NSS (New Nutrition Science)理论为基础，探讨社会支持对老年人营养状况和抑郁的调节作用，扩大了学术界的讨论。特别是对认知能力下降的老年人进行研究，可以作为实践和政策措施的基础数据，这是痴呆患病率高、认知功能轻度受损的老年人，具有重要意义。
