This study was conducted to investigate the dietary and other factors affecting bone mineral density (BMD) in older Korean women. A total of 340 women aged 65 to 74 were recruited from the Kugoksoondam area (Kurye, Goksung, Soonchang and Damyang counties), known as the longevity-belt region in Jeonla province, Korea. They were categorized into two groups according to bone status by T-score : a nonosteoporotic group and an osteoporotic group. Demographic characteristics were collected, as well as information on physical measurements, blood tests for biochemical indicators, health status health-related life style, dietary behavior, favorite food groups, nutrient intake and mini nutrition assessment (MNA). The results are as follows: The mean age of 185 nonosteoporotic women was 69.6 years and that of 155 osteoporotic women was 70.9 years (p<0.001). The mean T-score of the nonosteoporotic group was －1.5 mg/cm3 and that of theosteoporotic group was －3.2 mg/cm3 (p<0.001). Height and body weight in the nonosteoporotic group were significantly higher than in the osteoporotic group (p<0.001, respectively). There was no significant difference in BMI, although the BMI in the nonosteoporotic group was slightly higher. Waist and hip circumferences in the nonosteoporotic group were significantly higher than in the osteoporotic group (p<0.01, respectively), and the mid upper arm and calf circumferences were also significantly higher than in the osteoporotic group (p<0.001, p<0.01, respectively). The 5 m walking ability was significantly superior compared to the osteoporotic group. Serum levels did not show any significant differences between the groups and were within normal range. The serum total protein, albumin and Insulin-like growth factor (IGFs) levels of the nonosteoporotic group were significantly higher than those of the osteoporotic group (p<0.05, p<0.05, p<0.001, respectively). IGF was 104.7 ng/mL for the nonosteoporotic group and 88.1 ng/mL for the osteoporotic group. Physical activity and appetite in the nonosteoporotic group were significantly higher (p<0.01, p<0.05, respectively). The favorite food groups of the nonosteoporotic group comprised more meats and fish than those of the osteoporotic group (p<0.05, respectively). Nutrient intake was not significantly different, with the exception of niacin intake (p<0.05), but the nutrient intake of the nonosteoporotic group was slightly higher than that of the osteoporotic group. The niacin intake of the nonosteoporotic group and the osteoporotic group were 11.4 mgNE and 10.0 mgNE, corresponding to 103.6% and 90.9% of the Korean EAR, respectively. The MNA score of the nonosteoporotic group was significantly more favorable than for the osteoporotic group. In conclusion, it is necessary to maintain adequate body weight and muscle mass. Habitual physical activity may have a beneficial effect on BMD for older women. Dietary factors, such as meat and fish, higher intake of niacin rich foods and nutrient status for older women also appear to have favorable effects on bone mineral density.
