ABSTRACT

우리나라 65세 이상 노인 인구는 2011년 11.3%이며, 2050년에는 38.2%로 향후 선진국보다 높은 수준에 이를 것으로 예상된다(Korean Ministry of Health and Welfare, 2009). 일반적으로 재가 노인의 5-10%는 영양상태가 불량하며, 영양불량으로 인한 상태로, 근육소모 및 체중감소 등의 신체적 증상과 건강상태의 악화로 삶의 질이 낮아져 만성질환의 치료와 회복에 어려움이 따른다(Brownie, 2006). 노인은 저작장애, 식욕감소 등으로 채소, 과일 섭취는 부족한 것으로 보고되었으며(Korean Ministry of Health and Welfare, 2009) 다른 연령대에 비해 전반적인 영양소 섭취가 부족하다(The Ministry of Health and Welfare, 2009). 특히 여성은 남성보다 영양불량에 취약하며 연령이 증가할수록 영양상태가 불량한 것으로 보고되었다(Lee et al., 2003). 또한 노인에게 흔한 만성질환 중 당뇨(Franz, Horton, Bantle, & Beebe, 1994), 고지혈증(Park et al., 2010), 우울(Somoliner et al., 2009)은 노인의 영양에 영향을 미치는 것으로 보고되었다. 노인의 영양상태는 사회경제적 특성과 함께 독거 여부(Lee et al., 2003) 등에도 영향을 받으며 이는 개인의 의지로만 개선하기 어려우므로 지역사회 차원에서 노인의 영양개선을 위한 사회적 지지가 필요하다. 그러나 선행연구에서 영양상태에 관련된 신체적, 사회적, 정신적 요인을 포괄적으로 조사한 연구는 찾아보기 힘들다.

Purpose: The purpose of this study was to evaluate the nutritional status of elderly Korean women and to investigate related factors. Methods: A total of 100 elderly women attending a local elderly welfare center were recruited for study. Evaluation criteria included demographics, clinical status, nutritional status (using a mini-nutritional assessment), food intake, and nutritional bioparameters, including homocysteine, transferrin, prealbuminand lymphocyte levels, and their antioxidant power status. Results: Among the test group, 83% of the subjects were classified as undernourished, and they often had hyperlipidemia and a lower intake of fiber (p<.05, respectively) and vegetables than normal subjects. In a correlation analysis, their nutritional status was associated with abdominal circumference, the Korean Geriatric Depression Scale score and the Enriched Social Support Inventory score. Nutritional bioparameters and antioxidant power were associated with age among undernourished subjects. Old age, the prevalence of hyperlipidemia, and poor social support significantly increased the risk of undernutrition. Poor social support, the prevalence of diabetes mellitus and depression significantly increased the risk of nutritional deficiency after controlling for age, educational and economic variables. Conclusion: More strategies to increase social support in the Korean female elderly population may improve their nutritional status.
