背景：由于已知几种营养素会影响骨矿物质密度（BMD），因此对饮食模式或食物组合的分析可能有助于了解饮食对骨骼健康的影响。目的：我们评估日本农家妇女饮食模式与骨密度之间的关系。设计：本研究包括参加日本多中心环境毒物研究（JMETS; n = 1407）的291名绝经前农业妇女（40-55岁）。采用双能x线骨密度仪测量前臂骨密度。通过使用经验证的自我管理的饮食史问卷对饮食进行评估，问卷包括147种食物，从中创建了30种食物组并进入因子分析。结果：确定了四种饮食模式。“健康”模式，以大量摄入绿色和深黄色蔬菜、蘑菇、鱼类和贝类、水果和加工鱼为特征，在调整了几个混杂因素后，与骨密度呈正相关（P = 0.048）。相比之下，以脂肪和油、肉类和加工肉类的高摄入量为特征的“西方”模式往往与骨密度呈负相关；但相关性不显著（P = 0.08）。结论：高摄入鱼类、水果和蔬菜，低摄入肉类和加工肉类的饮食模式可能对绝经前妇女的骨密度有有益的影响。
Background: Because several nutrients are known to affect bone mineral density (BMD), the analysis of dietary patterns or combinations of foods may provide insights into the influence of diet on bone health.Objective: We evaluated associations between dietary patterns and BMD in Japanese farmwomen.Design: The study included 291 premenopausal farmwomen (aged 40-55 y) who participated in the Japanese Multi-centered Environmental Toxicant Study (JMETS; n = 1407). Forearm BMD was measured by using dual-energy X-ray absorptiometry. Diet was assessed by using a validated self-administered diet history questionnaire comprising 147 food items, from which 30 food groups were created and entered into a factor analysis.Results: Four dietary patterns were identified. The "Healthy" pattern, characterized by high intakes of green and dark yellow vegetables, mushrooms, fish and shellfish, fruit, and processed fish, was positively correlated with BMD after adjustment for several confounding factors (P = 0.048). In contrast, the "Western" pattern, characterized by high intakes of fats and oils, meat, and processed meat, tended to be inversely associated with BMD; however, the association was not significant (P = 0.08).Conclusion: A dietary pattern with high intakes of fish, fruit, and vegetables and low intakes of meat and processed meat may have a beneficial effect on BMD in premenopausal women.
