To evaluate the association between dietary quality and the prevalence of lower urinary tract symptoms (LUTS).
We used urinary symptom and dietary data obtained from the 2000-2001 National Health and Nutrition Examination Survey (NHANES) for the study. Dietary quality was assessed using the 10-component United States Department of Agriculture (USDA) Healthy Eating Index (HEI). We used bivariate methods to examine rates of LUTS among men with poor versus good diets. Multivariable logistic regression was used to calculate odds ratios after applying sample weights and controlling for age, race/ethnicity, smoking status, diabetes, alcohol intake, and exercise.
Our study cohort consisted of 1385 men aged ≥40 years, of whom 279 (21.1%) reported LUTS. We found higher rates of LUTS among men with poor dietary intake of dairy (22.4% vs 16.4%, P = .013) and among men with poor intake of protein (24.6% vs 17.9%, P = .012) as well as among those with overall poor diet (25.8 vs 17.8%, P = .018) with little dietary variety (26.1 vs 17.6%, P = .001). On multivariate analysis, an unhealthy diet (odds ratios [OR] = 1.7; 95% confidence interval [CI] = 1.05-2.90) was associated with more LUTS, whereas alcohol intake was protective from LUTS (OR = 0.67; 95% CI = 0.48-0.93).
In an analysis of NHANES data, we found that poor diet quality was independently associated with patient-reported LUTS.
评估饮食质量与下尿路症状（LUTS）患病率之间的关系。
我们使用 2000-2001 年全国健康和营养检查调查（NHANES）的尿症状和饮食数据进行了这项研究。饮食质量使用包含 10 个组成部分的美国农业部（USDA）健康饮食指数（HEI）进行评估。我们使用双变量方法检查了饮食不良和饮食良好的男性中 LUTS 的发生率。应用样本权重并控制年龄、种族/族裔、吸烟状况、糖尿病、酒精摄入量和运动后，使用多变量逻辑回归计算了比值比。
我们的研究队列包括 1385 名年龄≥40 岁的男性，其中 279 名（21.1%）报告有 LUTS。我们发现，饮食中乳制品摄入较差（22.4%对 16.4%，P =.013）和蛋白质摄入较差（24.6%对 17.9%，P =.012）的男性以及整体饮食较差（25.8%对 17.8%，P =.018）且饮食种类较少（26.1%对 17.6%，P =.001）的男性 LUTS 发生率更高。在多变量分析中，不良饮食（比值比[OR] = 1.7；95%置信区间[CI] = 1.05-2.90）与更多的 LUTS 相关，而饮酒则可预防 LUTS（OR = 0.67；95%CI = 0.48-0.93）。
在对 NHANES 数据的分析中，我们发现较差的饮食质量与患者报告的 LUTS 独立相关。
