Postmenopausal women were assessed to determine the association between dietary intake of various food groups and low bone mineral density. Among dietary factors, high consumption of protein-containing food and dairy products was associated with a reduced risk for low bone mineral density.
There have been several studies regarding the correlation between bone mineral density and dietary intake. In this study, we assessed the association between dietary habit and low bone mineral density among Korean postmenopausal women.
Bone mineral density of the lumbar spine was measured by dual energy X-ray absorptiometry in 2,501 subjects. A brief food frequency questionnaire, which included 16 food items, was used in this cross-sectional survey.
After adjusting for other risk factors related to low bone mineral density, a high intake frequency of protein-source food was associated with a lower risk for osteopenia (odds ratio (OR), 0.68; 95% confidence interval (CI), 0.54-0.87 for high vs. low intake frequency; p for trend, 0.02) and osteoporosis (OR, 0.76; 95% CI, 0.39-0.83 for high vs. low intake frequency; p for trend, 0.003), and a high intake frequency of dairy food was associated with a decreased risk for osteopenia (OR, 0.73; 95% CI, 0.57-0.94 for high vs. low intake frequency; p for trend, 0.018).
These results suggest that adequate nutrient intake is essential to maintain bone health in postmenopausal women.
本研究旨在评估绝经后女性的饮食摄入与低骨密度之间的关系。在饮食因素中，高蛋白和乳制品的高摄入量与低骨密度风险降低有关。
已有多项研究探讨了骨密度与饮食摄入之间的相关性。在这项研究中，我们评估了饮食习惯与韩国绝经后女性低骨密度之间的关系。
通过双能 X 射线吸收法测量 2501 名受试者的腰椎骨密度。在这项横断面研究中，使用了包含 16 种食物的简短食物频率问卷。
在校正与低骨密度相关的其他风险因素后，高蛋白源食物的高摄入频率与低骨量症（比值比（OR）为 0.68；95%置信区间（CI）为 0.54-0.87；p 趋势=0.02）和骨质疏松症（OR 为 0.76；95%CI 为 0.39-0.83；p 趋势=0.003）的风险降低相关，高乳制品摄入频率与低骨量症的风险降低相关（OR 为 0.73；95%CI 为 0.57-0.94；p 趋势=0.018）。
这些结果表明，绝经后女性需要充足的营养摄入来维持骨骼健康。
