Aim. The aim of this study was to investigate about diet assessment in the screening for osteoporosis.
Methods. In 1 441 women (group A, mean age 53.5 years, mean time from menopause 3.92(±4.33)] the number of daily/weekly servings/cups of different foods has been collected. In 71 women (group B, mean age 59 years, mean time from menopause 6 years) diet was assessed through a detailed questionnaire. Demographic and clinical data and dietary habits were related to bone mineral density (BMD) values, using Student t-test and the χ2 test.
Results. Group A: borderline/reduced BMD 40%, the percentage increasing with age and the duration of menopause (P<0.001). BMI within normal range 56.28%. BMD values were positively associated with Body Mass Index (BMI, P<0.001), education level (P<0.005), job (P<0.01), oral contraceptives use (P<0.001), negatively with family history of osteoporosis (P<0.05). BMD values showed a positive relation with the number of eggs per week (P<0.05), positive not significant trends were observed with dairy products, vegetables, red and white meat intake. A low/reduced BMD was related to low calcium food intake in less than 50% of the women. Group B: borderline/reduced BMD 55%; BMD showed positive trends, not significant, with daily calcium intake, BMI, physical exercise. Estimated calcium intake less than 700 mg/day was found in 33% of the sample.
Conclusion. Diet assessment is not useful in the screening for osteoporosis. In women with borderline or reduced BMD, diet assessment helps to detect those at low calcium intake who need calcium supplementation, alone or in combination with other treatments.
