지역사회 거주 여성노인의 근감소성 비만 유병률과 관련요인

Abstract

노인은 노화로 인하여 신체 조성에 다양한 변화가 나타나게 되는데, 지방량과 근육량의 변화가 가장 중요한 의미가 있다. 여러 종단적 연구에서 체지방량이 연령에 따라 증가하여 60-75세경 최고치에 도달하고, 근육량은 60세 이후에 더욱 빠르게 감소하는 것으로 보고되었다.

Purpose: The aims of this study were to identify prevalence and identify factors related to sarcopenic obesity among community-dwelling elderly women. Methods: This is a secondary analysis of the prospective cohort study. Our analysis included 338 elderly women (≥65 years old) in South Korea as a part of the Community-dwelling Older Adult Health Cohort (COHC) Study (2014-2015). Sarcopenic obesity was defined as the Asian Working Group of Sarcopenia recommendations and upper two quintiles for percentage body fat. Logistic regression analysis was used to determine the factors related to sarcopenic obesity including chronic diseases, medications, stress, fatigue, depression, exercise, level of proteins on body compositions, smoking, and alcohol use. Results: The prevalence of sarcopenic obesity was 6.2%. A lower protein on body compositions (OR 0.017, 95% CI 0.003-0.081, p<.001), a larger number of medications (OR 2.104, 95% CI 1.404-3.152, p<.001), and a higher level of fatigue (OR 1.255, 95% CI 1.023-1.541, p=.030) were related factors of sarcopenic obesity. Conclusion: The findings suggest that nutritional interventions focusing on protein intakes should be needed to prevent sarcopenic obesity among the elderly women. Polypharmacy issue for preventing adverse outcomes and level of fatigue as indicator for early identification are also considered to develop community prevention programs.
