INTRODUCTION. The aim of this study was to determine the prevalenceof decreased bone density of forearm bone as well as deficiencyin the calcium and vitamin D intake among young women.

MATERIALS AND METHODS. The study included 126 women inthe age of 23.8 ± 3.8 years (average ± standard deviation [SD]).The study has been performed in the period between 15 November2012 and 15 January 2013 based on the questionnaire of 24--hour dietary recall with data analysis using a computer softwareDieta 5.0. Additionally, a dual energy X-ray absorptiometry (DXA)method test has been performed in order to evaluate bone density of forearm bone (BMD and bone mineral content [BMC]) in twomeasurement points: proximal and ultradistal. Anthropometricanalysis has been also performed for the purposes of assessmentof basic body dimensions and indicators: body height, weight, armlength of nondominant limb.

RESULTS. Analyzing the results of measurements of BMD, in boththe distal and the proximal point (in relation to peak bone massT-score), cases of decreased bone mineralization of bone tissuehave been observed. The highest bone mineral density has beenobserved among obese women in the distal point and amongoverweight women in the proximal point. The lowest bone densityin both points has been found in women with body mass deficiency.The level of vitamin D (1.7 μg) estimated in the daily food ration(CRP) covered the level of adequate intake (AI) in 35.3%. As far ascalcium is concerned (570.1 mg), it has been found that its dailyintake supplied 55.4% of

AI.CONCLUSION. Decreased bone density among the examinedgroup of young women has been observed. Deficiency of elementsessential for bone mineralization, such as vitamin D and calcium,has been found. Examined women should be included in a programof nutrition education regarding the care of peak bone mass anda program of osteoporosis prevention.
