Public awareness regarding the influence of diet on kidney stones is unknown. We sought to evaluate such perceptions among an unselected community cohort. A survey was created to assess perception of beverages/foods on risk of kidney stone formation. Surveys were distributed to attendees of a State Fair. Participants were categorized to determine the effect of stone history on prevention knowledge (no prior stone prior stone). Seven hundred fifty-three participants completed the survey, including 264 (35%) with a prior stone. Participants with prior stones were less likely to believe stones were preventable compared to those without (56% 65%, = 0.01). Appropriate perceptions regarding influence of diet on stones were highest for water (>90% of participants) and cola/salt/red meat (>50%). Fewer than half of respondents correctly identified the influence of the remaining 14 substances. On multivariable analysis, stone formers were more likely to correctly identify the influence of lemonade (odds ratio [OR] 2.09; 95% confidence interval [CI] 1.32-3.31), nuts (OR 2.60; 95% CI 1.60-4.23), and spinach (OR 5.06; 95% CI 2.89-8.86), but less likely to identify the influence of coffee (OR 0.43; 95% CI 0.23-0.82) and red meat (OR 0.52; 95% CI 0.23-0.59). Patients with prior stones hold different attitudes regarding the influence of certain foods and drinks on stone formation relative to the public. Such attitudes are not always correct, and as a group they are less likely to believe in dietary stone prevention. Such findings may indicate confusion among stone formers and highlight an opportunity for improved dietary counseling.
公众对饮食对肾结石影响的认识尚不清楚。我们试图评估未选择的社区队列中的这种看法。我们创建了一项调查，以评估对饮料/食物对肾结石形成风险的看法。调查分发给州展览会的与会者。根据结石病史对参与者进行分类，以确定预防知识的影响（无结石史 有结石史）。共有 753 名参与者完成了调查，其中 264 名（35%）有结石史。与无结石史者相比，有结石史者认为结石可预防的可能性较小（56% 65%，= 0.01）。参与者对饮食对结石影响的正确看法最高的是水（>90%的参与者）和可乐/盐/红肉（>50%）。不到一半的受访者正确识别了其余 14 种物质的影响。多变量分析显示，结石形成者更有可能正确识别柠檬水（优势比 [OR] 2.09；95%置信区间 [CI] 1.32-3.31）、坚果（OR 2.60；95% CI 1.60-4.23）和菠菜（OR 5.06；95% CI 2.89-8.86）的影响，但不太可能识别咖啡（OR 0.43；95% CI 0.23-0.82）和红肉（OR 0.52；95% CI 0.23-0.59）的影响。与公众相比，有结石史的患者对某些食物和饮料对结石形成的影响持有不同的态度。这种态度并不总是正确的，而且作为一个群体，他们不太相信饮食可以预防结石。这些发现可能表明结石形成者之间存在混淆，并突出了改善饮食咨询的机会。
