OBJECTIVE
To evaluate whether there is a relationship between diet quality and bone health in a group of elderly Brazilian women.
METHODS
A cross-sectional study was performed with 105 elderly women. Participants were evaluated regarding diet quality (good, needing improvement, and poor) and its relationship with bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), and C-telopeptide (CTX).
RESULTS
Fifty eight participants (55.2%) presented a poor-quality diet and 47 (44.8%) required dietary improvements, while no subjects presented a good quality diet. The group requiring dietary improvements had lower CTX [0.35 (0.05;1.09) vs. 0.52 (0.10;1.45); p = 0.03)] and BSAP (38.7 ± 12.9 U/L vs. 46.10 ± 15.2 U/L; p < 0.01) levels than the poor-quality diet group. Groups did not differ in terms of BMD.
CONCLUSION
In this group of elderly Brazilian women, there was a relationship between diet quality and bone health, where worse diet quality was associated with higher levels of bone remodelling markers.
目的
评估一组巴西老年女性的饮食质量与骨骼健康之间是否存在关系。
方法
本研究为一项横断面研究，共纳入 105 名老年女性。评估参与者的饮食质量（良好、需要改善和较差）及其与骨密度（BMD）、骨特异性碱性磷酸酶（BSAP）和 C 端肽（CTX）的关系。
结果
58 名参与者（55.2%）饮食质量较差，47 名参与者（44.8%）需要改善饮食，而无良好饮食质量的参与者。需要改善饮食的组 CTX [0.35（0.05；1.09）比 0.52（0.10；1.45）；p = 0.03] 和 BSAP（38.7 ± 12.9 U/L 比 46.10 ± 15.2 U/L；p < 0.01）水平较低。两组间 BMD 无差异。
结论
在该组巴西老年女性中，饮食质量与骨骼健康之间存在关联，较差的饮食质量与更高的骨重塑标志物水平相关。
