Obese subjects have lower risk for osteoporosis than normal weight people. Body mass index over 33 kg/m2 is associated with lowest risk for hip fracture in both sexes.

Aim: Investigate overweight influence on bone mineral density of hip bone and lumbar spine in overweight postmenopausal women.

Material and methods: Postmenopausal women N=100, without co-morbidity, 48–88 years of age, divided in two groups: group A, with BMI 20–24.9 kg/m2 (N=19) and group B, BMI 25–29.9 kg/m2 (N=81). Bone mineral density (femoral neck and L1-L4) were measured by DEXA. Break point of T score for osteoporosis was −2.5 S.D.

Results: Group B have significantly higher hip bone mineral density, than group A (χ2=10.17, P=0.0014, χ2=7.96, P=0.0048). There was no significant differences between two groups in bone mineral densitu of lumbar sipne χ2=0.03, P=0.8558 with correction for continuality χ2=0.1, P=0.9186).

Conclusion: Postmenopausal women with BMI 25–30 kg/m2 have higher hip bone mineral density, aldo overweight has no influence on lumbar spine mineral density.
