摘要：Objective. Nutrition and lifestyle factors play an important role in the development and maintenance of peak bone mass and the prevention of bone degradation. The aim of the present study was to assess 25-hydroxycholecalciferol [25(OH)D] serum concentration in postmenopausal women during the winter period and the supply of selected components in their diet. Material and methods. The study was conducted on a group of 35 women aged 54–77, using a questionnaire, including a 24-hour recall related to a subject’s nutrient consumption. Serum concentrations of 25(OH) D were determined. Body composition was assessed with bioelectrical impedance analysis. Results. Mean 25(OH)D serum concentration was found to be 61.2% of the minimum healthy level, according to the reference values. The supply of vitamin D and calcium covered 36.2% and 56.7% of RDA respectively. Correlation analysis has shown a significant inverse relationship between 25(OH)D serum concentration and body fat (p < 0.05). Conclusions. The study indicates a decreased serum concentration of 25(OH)D in postmenopausal women during the winter period and a low supply of vitamin D and calcium in their diet. Nutrition education should be introduced to the adult population to prevent bone fractures.
