As the population ages, osteoporosis is a growing global public health problem. It is of great importance to identify modifiable risk factors of osteoporosis to promote bone health of the older population. This study examined the risk factors associated with osteoporosis in a nationally representative sample of Korean postmenopausal women from 2009 KNHANES (n=1,480, means age±SE=61.2±0.3). Bone mineral density of total femur, femoral neck, and spine was measured by X‐ray absorptiometry. Osteoporosis was determined as T‐score of −2.5 or below in at least 1 of 3 sites. Menopausal status was confirmed by self‐reports. Around 43% of the study sample had osteoporosis, and poor socioeconomic status, lower BMI, and shorter estrogen exposure duration were significantly associated with osteoporosis. Poor dietary intake was also related to osteoporosis. In the age‐adjusted logistic regression models, participants consuming protein, vitamin B2, or vitamin C less than EAR showed higher odds of having osteoporosis than their counterparts. Participants consuming no fish/shellfishes or no milk/milk products had 32% and 46% increased odds of having osteoporosis, respectively. The findings from this study suggest several modifiable risk factors that can be addressed in the development and implementation of tailored nutritional intervention programs to improve bone health of Korean postmenopausal women.
