Osteoarthritis (OA) is one of the most common diseases that cause disability among older adults. The objective of this study was to assess the association between adherence to the Dietary Approaches to Stop Hypertension (DASH) and OA in American adults. This study included adults (≥ aged 20 years) who participated in the National Health and Examination Survey (NHANES) 2007–2016 in the United States. Adherence to the DASH score was calculated from 8 food groups. Higher scores indicate better adherence to the DASH dietary pattern. Among the 21,901 participants included in this study, 10.26% reported having OA. Results of our multivariable logistic regression indicated a statistically significant inverse association between DASH score tertiles and OA. The adjusted ORs (95% CI) were 1.00 (ref), 0.89 (0.72; 1.10), and 0.78 (0.60; 1.00) across increasing DASH score tertiles (P for trend = 0.045). In this representative sample of American adults, greater adherence to the DASH dietary pattern was associated with lower likelihood of having OA.

骨关节炎（OA）是导致老年人残疾的最常见疾病之一。这项研究的目的是评估在美国成年人中坚持饮食控制高血压的方法（DASH）与OA之间的关联。本研究纳入了美国（2007年至2016年）国家健康和检查调查（NHANES）中的成年人（≥20岁）。从8个食物组中计算出对DASH评分的依从性。分数越高表明对DASH饮食模式的依从性越好。在这项研究中包括的21,901名参与者中，有10.26％的人报告患有OA。我们的多变量logistic回归结果表明DASH得分三分位数与OA之间存在统计学上的显着负相关。调整后的OR（95％CI）为1.00（参考），0.89（0.72; 1.10）和0.78（0.60; 1。趋势的P = 0.045）。在美国成年人的代表性样本中，对DASH饮食方式的更大依从性与较低的OA可能性相关。
