Studies investigating the effect of dietary calcium intake on bone mineral density in middle aged and old men are limited. The aim of this study was to determine the effects of dietary calcium intake on the risk of osteopenia and osteoporosis in middle aged and old men. It was a cross‐sectional study. A total of 1,217 male subjects aged 50–79 years from the 2009 Korean National Health and Nutrition Examination Survey participated in the study. Bone mineral density was measured using dual energy X‐ray absorptiometry. Calcium intake was estimated by 24‐hour dietary recall method. Prevalence of osteopenia at total femur, femoral neck, and lumbar spine was 13.5%, 40.0%, and 35.3%, respectively. Prevalence of osteoporosis at total femur, femoral neck, and lumbar spine was 0.5%, 3.5%, and 6.6%, respectively. The mean of calcium intake was 531.4±363.7 mg/d and 21.8% of the subjects fulfilled the Recommended Intake (RI) of calcium, 700mg/d. Dietary calcium intake was inversely associated with the risk of osteopenia and osteoporosis after adjusting for potential confounders at total femur (5th vs. 1st quintile, OR = 0.52, 95% CI = 0.27–0.99, P for trend = 0.010), femoral neck (5th vs. 1st quintile, OR = 0.47, 95% CI = 0.30–0.73, P for trend <0.0001), and lumbar spine (5th vs. 1st quintile, OR = 0.69, 95% CI = 0.46–1.05, P for trend = 0.037). These results suggest that adequate calcium intake is necessary to prevent osteopenia and osteoporosis in middle aged and old men.
