Plant foods are rich in many important micronutrients that are beneficial for bone health. This cross-sectional study of 9613 community-dwelling older adults found that more consumption of healthy plant foods and less consumption of animal foods and unhealthy plant foods were associated with a lower risk of osteoporosis.
Osteoporosis,a common chronic disease in older adults, threatens their health. Many nutrients in plant foods are important for preventing osteoporosis. However, the relationship between plant-based dietary patterns and osteoporosis remains unclear. This study aimed to investigate the cross-sectional association between plant-based dietary patterns and osteoporosis in older adults.
This study was conducted among 9613 community-dwelling older adults in Liaoning Province, China. The effective food frequency questionnaire (FFQ) and plant-based diet index (PDI) were used to evaluate compliance with plant-based dietary patterns. Osteoporosis was defined based on heel ultrasound. We analyzed the association between healthy plant-based diet index (HPDI) and unhealthful plant-based diet index (UPDI) and the risk of osteoporosis.
A higher PDI was associated with higher bone mineral density (BMD) in older adults. In logistic regression models, the highest quartile of PDI and HPDI had a significantly lower risk of osteoporosis than the lowest quartile, whereas UPDI in the highest quartile was associated with a higher risk of osteoporosis. There was a dose-response relationship between the three indices and the risk of osteoporosis. Subgroup analysis revealed differences in the relationship between HPDI and the risk of osteoporosis according to gender and age.
Older adults, especially women, consume more healthy plant foods and reduce the consumption of animal foods and unhealthy plant foods, which was associated with a lower risk of osteoporosis.
植物性食物富含许多对骨骼健康有益的重要微量营养素。这项对9613名社区居住的老年人进行的横断面研究发现，更多地食用健康植物性食物、更少地食用动物性食物和不健康植物性食物与较低的骨质疏松风险相关。
骨质疏松症是老年人常见的慢性病，威胁着他们的健康。植物性食物中的许多营养素对预防骨质疏松症很重要。然而，基于植物性的饮食模式与骨质疏松症之间的关系仍不清楚。本研究旨在调查老年人基于植物性的饮食模式与骨质疏松症之间的横断面关联。
本研究在辽宁省9613名社区居住的老年人中进行。使用有效的食物频率问卷（FFQ）和基于植物性的饮食指数（PDI）来评估对基于植物性饮食模式的依从性。骨质疏松症根据足跟超声进行定义。我们分析了健康植物性饮食指数（HPDI）和不健康植物性饮食指数（UPDI）与骨质疏松症风险之间的关联。
较高的PDI与老年人较高的骨密度（BMD）相关。在逻辑回归模型中，PDI和HPDI最高四分位数的骨质疏松风险显著低于最低四分位数，而UPDI最高四分位数与较高的骨质疏松风险相关。这三个指数与骨质疏松症风险之间存在剂量反应关系。亚组分析揭示了HPDI与骨质疏松症风险之间的关系在性别和年龄方面存在差异。
老年人，尤其是女性，多食用健康植物性食物并减少动物性食物和不健康植物性食物的摄入，这与较低的骨质疏松风险相关。
