서울지역 저소득층 여성의 비만 및 영양소 섭취 부족과 관련된 사회경제적 요인 = Socioeconomic Factors Relating to Obesity and Inadequate Nutrient Intake in Women in Low Income Families Residing in Seoul

국문 초록 (Abstract)

본 연구에서는 도시 저소득층 여성을 대상으로 비만 및 영양소 섭취 부족과 관련된 사회경제적 요인을 분석하고자 했다. 대상자는 저소득층 가구를 대상으로 한 무료건강검진 센터를 방문한 여성 중 연구 참여에 동의한 41~87세 125명의 여성이었다. 대상자들의 72%가 초등학교 이하의 교육, 70%가 50만원 미만의 수입, 68%가 집을 소유하지 않고 있는 것으로 나타났다. 대상자들을 65세 미만, 이상으로 나누어 봤을 때 65세 미만군의 비만유병율은 BMI (≥ 25 ㎏/㎡) 기준으로 44%, WHR (≥ 0.85) 기준으로 48%, 허리둘레 (≥ 80 ㎝) 기준으로 50%이었다. 65세 이상군에서는 이보다 높아 BMI (≥ 25 ㎏/㎡) 기준 57%, WHR (≥ 0.85) 기준 81%, 허리둘레 (≥ 80 ㎝) 기준으로 79%였다. 대상자는 주로 채소류, 곡류, 과일류를 많이 섭취했다. 모든 대상자에서 열량 및 영양소 섭취 상태는 대체적으로 불량했고 특히 65세 이상 노인에서 더욱 불량한 것으로 나타나 여자노인에서 EAR을 충족시키지 못하는 비율은 철을 제외한 모든 영양소에서 50% 이상이었다. 대부분의 대상자들의 영양소 섭취량은 RI 수준에 미치지 못했고 그러한 사람의 비율은 65세 미만의 경우 단백질과 Vitamin B6 제외한 65세 이상에서는 모든 영양소에서 50% 이상이었다. 65세 미만에서는 비만 및 영양불량과 사회경제적 지표와의 관련성이 없었다. 그러나 65세 이상에서 비만의 경우 수입과 영양불량의 경우 학력과 집소유 여부와 관련이 있었다. 따라서, 65세 이상에서 연령을 보정한 후에, 사회경제적 수준에 따른 비만 및 영양부족의 위험도를 살펴본 결과, BMI 기준 비만의 위험도 (OR = 12.601; 95% CI = 2.338-67.911)와 WC 기준 복부 비만의 위험도(OR = 4.778; 95% CI = 1.103-20.696)는 월평균 가구 수입 50만원 미만인군에서 그 이상인 군보다 높았다. 영양섭취불량의 경우, 교육 수준이 낮은 사람들 (무학)에게서 Vitamin A (OR = 4.555; 95% CI = 1.491-13.914)를 EAR보다 적게 섭취할 위험이 높았고 자기 집을 소유하지 않은 사람의 경우, 단백질 (OR = 3.660; 95% CI = 1.118-11.981), 인 (OR = 3.428; 95% CI = 1.157-10.158), 철분 (OR = 3.765; 95% CI = 1.205-11.766)섭취가 EAR보다 부족할 위험이 집을 소유한 사람들보다 높았다. 저소득층 노인여성에서 사회경제적 수준은 비만 (소득수준) 및 영양불량 [교육수준(Vitamin A), 자가집 소유 여부(단백질, 인, 철)] 위험과 관련이 있는 것으로 보여진다. 따라서 이러한 여성들의 비만 및 영양불량을 예방하기 위한 노력이 필요할 것으로 사료된다.

This study was performed to investigate socioeconomic factors relating to obesity and inadequate nutrient intake in women in low income families residing in Seoul. The subjects were 125 women (aged 41-87 y) recruited from the local health center for free health examination for low income families. The socioeconomic status such as educational level, income level, and housing condition were poor. For subjects aged less than 65 years, the prevalence of obesity was 44% based on BMI (≥ 25 ㎏/㎡), 48% based on WHR (≥ 0.85), and 50% based on waist circumference (≥ 80 ㎝) and for those more than 65 years, these were greater and 57%, 81%, and 79%, respectively. The main food sources of daily diet were vegetables, grains, and fruits. Energy and other nutrient intake was not adequate for all subjects and the inadequacy was more profound in the elderly, showing percentages of subjects whose intake was less than EAR were greater than 50% for all nutrients except for iron and below RI were also greater than 50% for all nutrients. The prevalence of obesity and nutrient inadequacy were not associated with socioeconomic status in subjects aged less than 65 years, however, obesity was associated with household income and nutrient inadequacy was related to education (vitamin A) and housing status (protein, phosphate, and iron) in the elderly. After adjustment for ages, in the elderly, OR for obesity (BMI ≥ 25, OR = 12.601; 95% CI = 2.338-67.911) and central obesity (WC ≥ 80 ㎝, OR = 4.778; 95% CI = 1.103-20.696) were greater in subjects who earned less than 500 thousand Won per month than who earned more. For inadequate nutrient intake, the OR for inadequate intake of Vitamin A (OR = 4.555; 95% CI = 1.491-13.914) was greater in subjects with no education than those educated. Subjects without her own house had greater risk for inadequate intake for protein (OR = 3.660; 95% CI = 1.118-11.981), phosphate (OR = 3.428; 95% CI = 1.157-10.158), and iron (OR = 3.765; 95% CI = 1.205-11.766) than subjects possessing her house. In elderly females in low income families, the socioeconomic status was associated with the risk for obesity (income level) and inadequate nutrient intake (education level and housing status). More attention on these groups should be given for prevention of obesity and inadequate nutrient intake.
