초록

본 연구는 식품불안정이 일반적 특성, 신체적 및 정신적 건강상태, 영양소 섭취량, 한국인영양섭취기준 (KDRIs) 대비 영양소 부족 섭취자의 비율, 식사의 질과 다양성 등에 미치는 영향을 밝히고자 하였다. 이에 제 5기 1차년도 (2010년) 국민건강영양조사 (KNHANES) 자료를 이용하여 65세 이상 노인 939명을 대상으로 하였고, 연구 결과를 요약하면 다음과 같다. 1) 식품불안정은 측정항목의 답변에 따라 총 3개의 그룹인 food secure 군 (FS)과 mildely food insecure 군 (FI 1), moderately/severly food insecure 군 (FI 2)으로 분류하여 분석에 이용하였다. FS군은 33.1%를. 식품불안정군 (FI 1, FI 2)은 67%를 차지하여, 전체대상자의 약 2/3가 식품불안정한 상태에 있는 것을 알 수 있었다. 2) 식품불안정에 따른 일반적 특성에서는 연령, 배우자의 유무, 교육수준, 소득수준에서 유의적인 관련성을 보였다. 식품 공급이 불안정 할수록 평균 연령이 높아졌으며, 교육수준과 소득수준은 낮아졌다. 식품불안정군에서 이혼과 사별을 포함하는 배우자가 없는 경우가 배우자가 있는 경우보다 더 많은 비율을 차지하고 있었는데, 이는 사별을 많이 경험하게 되는 노인에게서 유의미한 결과를 나타내었다. 3) 건강상태를 파악하기 위해 신체적 건강과 정신적 건강을 분석하였는데, 식품불안정 정도가 심각해질수록 건강상태가 좋지 못한 것으로 나타났다. 한국 노인에서는 식품불안정이 신체적 건강보다는 정신적 건강에 더 큰 영향을 미치는 것을 알 수 있었다. 스트레스 인지, 우울 증상 경험, 자살 생각여부를 포함하는 정신적 건강에서 식품불안정 정도가 심각해질수록 그 위험성이 커지는 것을 알 수 있었으며, 특히 식품불안정은 우울 증상을 야기할 뿐만 아니라 우울증의 유지요인으로 작용 하는 것으로 조사되었다. 4) 식품불안정과 영양섭취상태와의 관련성을 파악하기 위해 에너지 비율과 영양소 섭취량, 한국인영양섭취기준 대비 영양소 부족 섭취자의 비율을 조사하였는데, 대부분의 영양소에서 식품불안정군의 절대적인 섭취량이 적었고, 영양섭취기준보다 부족하게 섭취하는 자의 비율이 높았다. 5) 식품불안정군의 식사의 질과 식사의 다양성이 떨어지는 것으로 나타났고, 특히 식사의 다양성을 조사한 총 식품 점수 (DVS)와 식품군 점수 (DDS)에서 식품안정군과 식품불안정군 간의 점수 차이가 큰 것으로 나타났다. 결론적으로 한국 노인에게 식품불안정이 신체적 및 정신적 건강상태를 악화시키고 식이섭취상태에 부정적인 영향을 미치는 요인으로 작용하는 것으로 나타났다.

Purpose: The purpose of this study was to examine the prevalence of food insecurity in Korean elderly and to analyze the health status as well as food and nutrient intakes according to food insecurity status. Methods: A total of 939 elderly subjects (over 65 years old) were used in our analysis from the fifth 2010 Korean National Health and Nutrition Examination Survey (KNHANES V-1). The variables consisted of general characteristics, physical and mental health, nutrient intake, rate of deficient intake of energy and nutrients compared with Dietary Reference Intakes for Koreans (KDRIs) and food quality and diversity according to the status of food insecurity. Food insecurity status was measured using a self-reported food security questionnaire on the dietary situation in the previous year, and participants were classified according to three groups: food secure group, mildly food insecure group, and moderately/severely food insecure group. Results: The proportion of the food insecure group was approximately 67% and the food insecure group had lower income and educational status than the food secure group. Food insecurity was associated with worse physical and mental health status after adjusting potentially confounding variables. The results showed that food insecurity in Korean elderly significantly affected mental health (including stress cognition, depression experience, and suicide thoughts) which exceeded stages of physical health. In addition, food insecurity showed significant association with low nutrient intake and high rate of deficient intakes of energy and nutrients compared with KDRIs, and a reduction of dietary quality and diversity was indicated in the food insecure group. Conclusion: This study concludes that the prevalence of food insecurity may affect the physical and mental health as well as dietary intake of the elderly Korean population. Therefore, food insecurity should be considered as an important public health issue in Korea.
