Osteopenia and Osteoporosis Among 16–65 Year Old Women Attending Outpatient Clinics

Women living in developing countries are more prone to osteoporotic fractures than women in developed countries. The objectives of this study were to estimate the burden of osteopenia and osteoporosis and examine their correlates among Bangladeshi women. This cross-sectional study consisted of 500 women aged 16–65 years attending gynecology and family planning clinics of a tertiary hospital which cares urban/suburban low income population in Dhaka, Bangladesh. Bone mineral density (BMD) was measured at the lumbar spine and femoral neck using dual X-ray absorptiometry. We calculated T scores based on sex-matched reference data from Caucasian women provided by the manufacturer. Osteoporosis was defined as a BMD at either site more than 2.5 standard deviations (SD) below the young healthy adult woman mean while the osteopenia was defined as a BMD between 1 and 2.5 SD below the mean as suggested by the World Health Organization. Separate multivariable logistic regression analysis was used to examine the correlates of osteopenia/osteoporosis among 16–45 and 46–65 year old women. Overall, 43.6 and 5.5 % of 16–45 year old women, and 40.7 and 41.8 % of 46–65 year old women had osteopenia and osteoporosis based on T scores either of the two sites (lumbar spine or femoral neck), respectively. Body mass index was negatively associated with osteopenia/osteoporosis at both lumbar spine and femoral neck, while age was positively associated. The burden of osteopenia/osteoporosis is very high in Bangladeshi women which warrants appropriate interventional strategies to minimize future fractures and reduce related social and economic burden of the society.
