Abstract Summary This is the first study to examine the association of adherence to the dietary approaches to stop hypertension (DASH) dietary pattern and osteoporosis risk in postmenopausal Iranian women. Findings suggest the inverse association of adherence to the DASH dietary pattern and osteoporosis risk in postmenopausal Iranian women. Introduction This study was aimed to examine the association of adherence to the dietary approaches to stop hypertension (DASH) dietary pattern and osteoporosis risk in postmenopausal Iranian women, hypothesizing that higher adherence to this pattern is associated with lower risk of postmenopausal osteoporosis. Methods One hundred fifty-one postmenopausal Iranian women aged 50–85 years participated in this cross-sectional study. Lumbar spine and femoral neck bone mineral densities (BMDs) were measured via dual-energy X-ray absorptiometry. Postmenopausal osteoporosis was then defined using the WHO criteria as a BMD T-score of ≤ − 2.5 standard deviations. The usual past-year dietary intakes were assessed by a valid and reliable 168-item food frequency questionnaire. The DASH score was then calculated based on energy-adjusted intakes of eight major dietary components usually emphasized (i.e., fruits, vegetables, nuts and legumes, low-fat dairy products, and whole grains) or minimized (i.e., sodium, sweets, and red or processed meats) in the DASH diet. The higher the DASH score of a participant, the higher the adherence to the DASH dietary pattern. Results After adjusting for several potential covariates in the multivariable-adjusted binary logistic regression analysis, participants in the highest tertile of DASH score had lower risk of osteoporosis at lumbar spine than those in the lowest tertile (odds ratio = 0.28; 95% confidence interval, 0.09–0.88; p = 0.029). However, no significant association was observed between adherence to the DASH dietary pattern and risk of osteoporosis at femoral neck. Conclusion Findings suggest the inverse association of adherence to the DASH dietary pattern and osteoporosis risk in postmenopausal Iranian women. Keywords Bone density . Diet . Iran .
