The aim of this study was to analyse differences in bone density and vitamin D and calcium concentrationsbetween pregnant and non-pregnant women. Methods: This was an analytical, cross-sectional study of women aged 30years or over, residing in the Puskesmas Bangkalan district. The sample population was chosen at random and included10 pregnant women in their third trimester and 10 non-pregnant women. This observational study consisted of aninterview, a blood test, and a 24-hour recall. The concentration of serum vitamin D (25(OH)D) was measured by GasChromatography and a Photometric Test measured the concentration of serum calcium. Participant’s bone density wasmeasured by bone ultra sonometer. The data was analysed using the Mann-Whitney test and assessed ultraviolet-Bexposure, bone density values, and consumption of vitamin D, calcium, energy, and protein. The Student t-test wasused to analyse serum vitamin D and calcium concentrations. Results: There were no differences between the groups’serum vitamin D concentrations (p = 0.946). However, there were significant differences between the groups’ serumcalcium concentrations (p = 0.047) and bone density values (p = 0.019). Conclusions: A high prevalence of vitamin Ddeficiency (25(OH)D < 50 nmol/L) and insufficiency (25(OH)D < 80 nmol/L) was observed in both groups. The meanserum calcium concentrations and bone density values were lower in pregnant subjects than non-pregnant subjects. |
