The objective was to investigate the association of nutrients and lifestyle modifiers with bone mineral density (BMD) and weight and/or body mass index (BMI) in 120 healthy Croatian postmenopausal women. The hip and spine BMD was assessed by Lunar Prodigy (GE Medical Systems). Nutrient assessment from 3-day records was analyzed using the US Department of Agriculture Food Composition Tables and the Croatian National Institute of Public Health database. Subjects were asked to record the consumption of alcohol, coffee, tea and mineral waters, the amount of salt added to foods and smoking habits, as well as involvement in recreational activities, walking and heavy housework. Spot urine samples were analyzed for calcium, magnesium, sodium, potassium and zinc and were normalized by creatinine. Alcohol showed statistically significant positive association with femur and spine BMD and its consumption was higher in subjects without osteoporosis. Urinary sodium/creatinine was significantly positively associated with femoral neck and trochanter BMD, while urinary calcium/creatinine was significantly negatively associated with trochanter, total femur and spine BMD. Consumption of mineral waters was inversely associated with weight/BMI and so were dietary fiber and magnesium. In conclusion, moderate alcohol consumption and urinary sodium were positively associated while urinary calcium was negatively associated with either hip and/or spine BMD. Mineral waters, higher fiber and magnesium intake were beneficial for weight/BMI in this population of apparently healthy Croatian women. [ABSTRACT FROM AUTHOR]
