Abstract

Our objective was to determine the effects of dietary calcium intake on body composition of Koreans in Hawaii. The study population constituted of 72 Koreans (Men 29, Women 43) aged 18–45 years and living on Oahu. Nutrient intake data was obtained by 3 days of 24-hour diet recalls and anthropometric data (height, weight, and abdomen, suprailiac, and triceps skinfolds) were obtained by measurement. Body Mass Index (BMI) and percent body fat were calculated from weight and height, and sum of abdomen, suprailiac, and triceps skinfolds, respectively. The mean BMI (kg/m2) and body fat (%) were 23.5 and 15.1 in men and 21.9 and 27.1 in women, respectively. The mean energy and calcium intakes were 1851 kcal and 516 mg in men and 1449 kcal and 509 mg in women, respectively. The main sources of calcium were 2% milk (17% of the intake), dried small fish (6.2%), whole milk (5.6%) and Kim Chee (5.4%). After age and sex adjustment, the calcium intake was significantly negatively associated with the percent body fat, BMI and abdomen skinfold (p<0.05); total dairy intake was significantly negatively associated with the abdomen skinfold (p<0.05) and yogurt intake significantly negatively associated with percent body fat and abdomen skinfold (p<0.05). Higher calcium intake is associated with lower body fat in Koreans. Funded by NCI Grant # CA90956.
