Objectives: To determine relationship between milk, cheese, low fat milk, bread, icecream, egg, doghnut, bean, yogurt, protein intake and bone mineral density of lumbar and femur sites in korean postmenopausal women.
Methods: A cross-sectional study in 1,105 Korean menopausal women, mean±SD age 55.81±6.99 years, all healthy and free of medications affecting bones, including estrogen. Bone mineral density (BMD) of lumbar and femur regions were measured by dual X-ray absorptiometry. Milk, cheese, low fat milk, bread, icecream, egg, doghnut, bean, yogurt, protein intake was assessed by food frequency questionnaire.
Results: Protein intake was positively associated with lumbar Z-score (r = 0.114). Low fat milk, protein, bread and cracker, egg, doghnut intake was decreased risk of osteoporosis or osteopenia in lumbar spine, which results were consistent after adjustment with age and BMI. Protein intake decreased risk of osteopenia of total femur and bread and cracker intake decreased risk of osteoporosis of femur neck, which result were consistent after adjustment with age and BMI.
Conclusion: Protein intake was positively associated with lumbar Z-score. The results support the notion that consumption of low fat milk, protein, bread and cracker, egg, doghnut were decreased risk of osteoporosis or osteopenia.
