Abstract

Purpose: This study was conducted to evaluate the factors influencing inadequate energy intake among Korean elderly. Methods: Our study included 1,869 elderly people (over 60 years old) who completed a dietary survey from the fifth Korean NHANES (2010). Factors that could affect the nutritional status of the elderly included age, family status, socio-economic factors (education, family income, livelihood security, employment), and health related factors (having chronic disease, functional status, diet therapy, depression, and suicidal thoughts). Energy and protein intake were assessed using the dietary intake data from 24hr recall method. Results: The percentage of people who consumed energy less than 75% of EEA for Koreans was 23.7% in men, 31.1% in women. The carbohydrate contribution to the total energy intake in the inadequate energy intake group was significantly higher than that in the adequate intake group (p < 0.05). Factors significantly related to inadequate energy intake after adjusting for age, family status, education, family income, employment, functional status, and suicidal thoughts were education (OR: 1.480 in men, 1.614 in women) and employment (OR: 1.751 in men, 1.464 in women), age 70 years or older in men (OR: 1.475), and living with family but without spouse in women (OR: 1.496). Conclusion: In summary, the results imply that energy intake of elderly would be affected by the status of social environment with aging and nutrition-related policy for Korean elderly should be based on the social status as well as health related conditions.

본 연구는 우리나라 노인세대가 겪는 사회환경요인이 에너지 섭취 부족에 어떠한 영향을 주는지 알아보고자 제5기 1차년도 (2010) 국민건강영양조사 자료를 바탕으로 분석을 실시하였으며, 결과를 요약하면 다음과 같다. 1) 남녀 모두 연령이 70세 이상이고, 경제활동을 하지 않는 경우, 활동제한이 있는 경우 에너지 섭취 부족 비율이 높은 것으로 나타났다. 그 밖에 남자는 배우자는 없이 가족과 동거하는 경우, 학력, 그리고 가구소득, 여자는 자살생각 여부가 에너지 섭취량에 영향을 주는 것으로 분석되었다. 2) 에너지 필요 추정량의 75% 미만으로 섭취하는 노인의 비율은 남자는 23.7% (196명), 여자는 31.1% (324명)으로 나타났으며 에너지 섭취량이 75% 미만인 그룹의 경우 탄수화물 섭취 비율이 유의적으로 높은 것으로 분석되었다. 3) 에너지 섭취가 부족한 그룹의 경우 남녀 모두 돼지고기와 소고기가 10위 안에 포함되지 않았고 배추김치와 된장이 20위 안의 주요 급원식품에 들었다. 4) 최종적으로 남녀 모두 학력 (남자: OR = 1.480, 여자: OR = 1.614)과 경제활동 여부 (남자: OR = 1.751, 여자: OR = 1.464)가 에너지 섭취 부족에 영향을 주는 요인으로 분석되었으며, 이 외에도 남자는 70세 이상의 고령 (OR = 1.475), 여자는 배우자 없이 가족과 동거하는 경우 에너지 섭취 부족일 확률이 1.496배로 나타났다. 이상의 연구 결과 노인의 에너지 섭취량은 노화로 인한 신체적 생리적 변화 외에도 노인이 속한 사회환경, 사회구조적 변화에 민감하게 반응한다는 것을 확인할 수 있었다. 효과적인 노년기 영양관련 정책 수립을 위해서는 사회환경의 변화에 따른 영양취약계층을 선별하는 것이 무엇보다 중요하므로, 본 연구에서 확인한 노인의 에너지 섭취 부족과 관련된 요인들은 노년기 영양정책을 계획하는 데 있어 기초자료로 활용될 수 있을 것으로 사료된다.
