Abstract :
Background: To investigate the relationship between different dietary patterns and the levels of bone mineral density (BMD) in middle-aged and aged people, and to provide references for the nutritional prevention of os-teoporosis.
Methods: A total of 476 residents aged 45 yr or more in Qiqihar City were enrolled from Aug 2018 to Feb 2019. They took a Food Frequency Questionnaire for dietary survey. Their dietary patterns were analyzed using the factor analysis method, and BMD were detected using ultrasound bone densitometer, to explore the rela-tionship between different dietary patterns and BMD levels.
Results: Four dietary patterns were obtained in the survey: relatively balanced, oil-salt, milk-tuber, and aquatic. Among them, the prevalence of osteoporosis reached 21.8%. High-level relatively balanced dietary pattern (OR=0.588, 95%CI= 0.363-0.951) and high-level dairy-potato food dietary pattern (OR=0.668, 95%CI= 0.370-0.983) were associated with lower risk of osteoporosis.
Conclusion: A balanced diet and a high intake of dairy-potato food dietary pattern were associated with a lower prevalence of osteoporosis. It is recommended that middle-aged and aged people should have a balanced diet with more dairy products and potatoes to protect bone health.
