■骨密度(BMD)是预测骨折风险和诊断骨质疏松症的重要指标。随着全球骨质疏松症患病率的上升,了解膳食模式与骨密度之间的关系对公共卫生至关重要。这项研究旨在使用国家健康与营养调查(NHANES)的数据探索成年人的各种饮食模式与BMD之间的关联。
■分析了2013年至2020年三个非连续调查周期中8,416名40岁及以上的NHANES参与者的数据。使用因子分析和聚类分析的组合来确定饮食模式。然后评估BMD测量值,并分析了与确定的饮食模式的关联,对人口变量进行了调整。
■分析确定了三种不同的饮食模式:“低蛋白高膳食纤维-维生素A-镁(LP-HDF-VitA-Mg)”“高常量营养素-胆碱-硒(HM-Cho-Se)”,和“低常量营养素-维生素D-钙(LM-VitD-Ca)”然后我们发现女人,老年人,某些种族群体的低BMD风险较高。与遵循“LM-VitD-Ca”模式的参与者相比,坚持“HM-Cho-Se”和“LP-HDF-VitA-Mg”饮食模式的参与者表现出更高的BMD。在调整人口统计学变量后,“HM-Cho-Se”模式与骨密度保持正相关,而“LM-VitD-Ca”模式与BMD或低BMD风险无显著关联。
■研究结果表明,坚持“HM-Cho-Se”饮食模式可能会降低低骨密度的风险,表明这些营养素对骨骼健康的潜在协同作用。然而,这项研究有局限性,包括因子分析中的横断面设计和潜在主观性。未来的研究应集中在涉及不同年龄段的纵向研究上,以更好地了解饮食模式与BMD之间的因果关系。尽管有这些限制,该研究强调了饮食因素对维持骨骼健康的重要性,并提出了潜在的饮食干预措施,以降低低骨密度和骨质疏松症的风险.
UNASSIGNED: Bone mineral density (BMD) is a crucial index for predicting fracture risk and diagnosing osteoporosis. With the global rise in osteoporosis prevalence, understanding the relationship between dietary patterns and BMD is vital for public health. This study aimed to explore the association between various dietary patterns and BMD among adults using data from the National Health and Nutrition Examination Survey (NHANES).
UNASSIGNED: Data were analyzed from 8,416 NHANES participants aged 40 years and older across three non-consecutive survey cycles from 2013 to 2020. Dietary patterns were identified using a combination of factor analysis and cluster analysis. BMD measurements were then assessed, and associations with the identified dietary patterns were analyzed, with adjustments made for demographic variables.
UNASSIGNED: The analysis identified three distinct dietary patterns: \"Low protein-High Dietary fiber-Vitamin A-Magnesium (LP-HDF-Vit A-Mg)\", \"High macronutrient-Choline-Selenium (HM-Cho-Se)\", and \"Low macronutrient-Vitamin D-Calcium (LM-Vit D-Ca)\", and then we found that women, older adults, and certain ethnic groups were at higher risk for low BMD. Participants adhering to the \"HM-Cho-Se\" and \"LP-HDF-Vit A-Mg\" dietary patterns exhibited significantly higher BMD compared to those following the \"LM-Vit D-Ca\" pattern. After adjusting for demographic variables, the \"HM-Cho-Se\" pattern remained positively associated with BMD, while the \"LM-Vit D-Ca\" pattern showed no significant association with BMD or the risk of low BMD.
UNASSIGNED: The findings suggest that adherence to the \"HM-Cho-Se\" dietary pattern may reduce the risk of low BMD, indicating potential synergies between these nutrients for bone health. However, the study has limitations, including the cross-sectional design and potential subjectivity in factor analysis. Future research should focus on longitudinal studies involving diverse age groups to better understand the causal relationship between dietary patterns and BMD. Despite these limitations, the study highlights the importance of dietary factors in maintaining bone health and suggests potential dietary interventions to reduce the risk of low BMD and osteoporosis.
