Abstract

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 (> or = 25 kg/m2), 48% based on WHR (> or = 0.85), and 50% based on waist circumference (> or = 80 cm) 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 > or = 25, OR = 12.601; 95% CI = 2.338-67.911) and central obesity (WC > or = 80 cm, 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.
