This study was conducted to investigate bone density and food behavior of middle-aged (〈65-years-of-age) and oldaged women (≥65-years-of-age) in the Seoul area of Korea. Average height and weight, body mass index, body fat percentage, and waist-hip ration (WHR) of the middle-aged participants were 158.0 cm, 58.4 kg, 23.3, 29.7%, and 0.88. Corresponding measurements for old-aged participants were 152.6 cm, 56.3 kg, 24.1, 33.1%, and 0.93. T- and Z-scores for middle-aged women were -1.20 and -0.21, and those of old-aged women were -2.02 and -0.49. Osteopenia and osteoporosis percentage of middle- and old-aged women were 41.2% and 14.7%, and 45.2% and 37.1%, respectively. Significant differences were evident concerning between-meal, overeating, exercise, and nutritional supplementation among the two groups. Middle-aged women displayed a positive relationships between bone density and the parameters of height (p〈0.05), weight (p〈0.05), exercise (p〈0.05), consumption of soybean and soybean-processed food (p〈0.05), and negative relationships between bone density and the parameters of WHR (p〈0.001), consumption of meat and meatprocessed food (p〈0.05), and tea drinking (p〈0.05). In old-aged women group, positive relationships were evident for bone density and the parameters of height (p〈0.05), weight (p〈0.05), exercise (p〈0.05), nutritional supplementation (p〈0.05), and consumption of soybean and soybean-processed food (p〈0.05). The results reveal a link between healthy bones and desirable food behavior, indicating the importance of a practical and systematically organized food behavior education program for middle- and old-aged Korean women.
