Aim: We aimed to determine the relationship between bone mineral density and body mass index in postmenopausal women. Material and Methods: 54 postmenopausal women were included in the study. Age and time of menopause were recorded. Smoking, alcohol and exercise status were also recorded. Weight and height were measured and body mass index was calculated. The patients were separated into four groups according to their body mass index, as underweight, ideal weight, over-weight and obese. Bone mineral density in all the patients was assessed via dual energy X-ray absorptiometry from antero-posterior lumbar and right proximal femoral regions. For L2-4 and the femoral neck, bone mineral density and t scores were determined. Results: The study was performed in 54 postmenopausal women, ranging in age from 51 to 79 years. 22 (%40.8) of the patients were obese, 24 (%44.4) were overweight and 8 (%14.8) had ideal weight. There were no patients in underweight group. There were no difference in age, smoking, time of menopause, bone mineral density and t-scores among the groups. There was statistically significant correlation between body mass index and bone mineral density of the femoral neck (r =0.407, p=0.002), and femoral neck t-scores (r =0.297, p=0.029). There was no significant correlation between the body mass index and lumbar bone mineral density and lumbar t-scores (p >0.05). Conclusion: Body mass index was found to be related to bone mineral density of the femoral neck. Our findings suggest that maintenance of adequate body mass is important for the prevention of postmenopausal bone loss. (From the World of Osteoporosis 2007;13:56-9)
