Milk and milk products consumption and somatometric parameters in relation to bone density of females

The aim of the study was to evaluate the influence of the nutritional habits - milk and milk products consumption and anthropometric parameters on bone density in women. In the study of the health-nutritional status took part 195 women at the age of 14-74 years (average age 48.3 years). In randomly selected women were with the aim osteoporosis prevalence examination measured the bone mass density of the calcaneus using the ultrasonically method of osteodensitometry. According to the obtained T-score values, the probands were divided into three groups: a - women with negative diagnosis and with normal T-score values, i.e. higher than -0.99, b - women with osteopenia, i.e. with decreased bone mass density or with higher risk of fracture and with T-score values from -1.0 to -2.49, c - women with osteoporosis, i.e. with high risk of fracture and with T-score values less than -2.5. Along with the bone mass were observed also anthropometric parameters in examined women (actual body weight, body height, body mass index BMI, ideal weight, difference between real and ideal weight, waist to hip ratio, waist to height ratio, body fat) and using the form of questionnaire was evaluated the milk and milk products consumption. The results were statistically evaluated with T-test and chi-square test. From the results follows that in the tested group of females 50,3 % had T-score values more than -0.99 (group a), 45.1 % women had T-score values varying from -1.0 to -1.49 (group b), and 4.6 % were included into group c, when their T-score values were less than -2.5. It was confirmed the influence of the higher age as the risk factor of the osteoporosis formation and development, when the highest age had the women in group a1 (a1 - conected groups b+c, i.e. of women with osteopenia and osteoporosis). The next risk factor was found body weight, mainly astenic body type, where BMI - index values were very low. When the BMI-index values were low, the risk of osteoporosis formation and development is increased. The highest body weight, difference between real and ideal weight and values of BMI-index were found in group a. Significant differences in present milk consumption and in milk products consumption at the age up to twenty years were observed in the group of females a and a sup (1).
