The aim of the study reported here was to investigate low bone mineral density and its associated risk factors in postpartum women. Materials and methods: The sample consisted of 93 females aged 18-40 years and in the first month of the postpartum period. All the women had low back pain. The bone mineral density (BMD) Z-score values of the lumbar vertebrae, femur (neck and total) were examined using dual energy x-ray absorbtiometry four weeks after birth. Patients body mass index (BMI), 25-hydroxyvitaminD (25-OHD) levels and complete blood counts were recorded. Participants were divided into two groups to their Z scores: the normal group (n = 71) and the low BMD group (n = 22). Results: The 25-OHD levels were significantly lower (p = .02) in the low BMD group [4.45 (4.0-12.4)] than in the control group [22 (12-48)], however, NLR and PLR values were similar between groups. BMI positively correlated with BMD scores for the lumbar, femoral neck and femoral overall (p = .011, p = .026 and p = .026, respectively). Conclusion: Vitamin D deficiency and BMI may play a critical role in PAO. Low back pain during postpartum period should be carefully evaluated. Adequate calcium and vitamin D supplementation may prevent possible bone loss. (C) 2019 Taiwan Association of Obstetrics & Gynecology.
