: The urine sodium/potassium (Na/K) ratio can potentially be used to detect dietary habits that contribute to hypertension. In this prospective cohort interventional trial, we aimed to verify whether private insurance sales staff can help clients change their lifestyle habits based on their urinalysis results. Clients of the life insurance company (20-65 years old) who were considered to have "high risk" lifestyle factors, which was defined as having high values for two or more of the following indicators: body mass index, blood pressure, triglycerides, liver enzymes, and glucose metabolism, were included. The clients were randomly assigned to three groups: a face-to-face (FF) intervention by sales staff (n = 83), non-FF (Non-FF) intervention via a social networking service (n = 87), and no intervention (Control) (n = 58). Urinalysis and surveys about diet and exercise habits were conducted before and after a 3-month interventional period in all groups. Three interventions were performed for the FF and Non-FF groups, including dietary advice based on urinalysis results, education encouraging reduced salt intake and increased locomotor activity, and viewing an educational video. The Control group only received their urinalysis results by mail. The participants' mean age was 44.0 years old. Significant improvements in estimated potassium intake were observed in the Non-FF group, and significant reductions in urine Na/K ratios were noted in both the FF and Non-FF groups. Multiple logistic regression analysis indicated that watching the video was the most effective factor for decreasing the urine Na/K ratio (odds ratio = 1.869). The total points for dietary behavior, based on the questionnaire, significantly improved among the individuals who watched the video. This study demonstrates the potential for private health insurance companies to contribute to health promotion and introduces a novel strategy for improving lifestyle habits among individuals at high risk of lifestyle-related diseases.
尿钠/钾（Na/K）比值有可能用于检测导致高血压的饮食习惯。在这项前瞻性队列干预试验中，我们旨在验证私人保险销售人员是否能够根据客户的尿液分析结果帮助他们改变生活方式习惯。纳入了人寿保险公司20至65岁的客户，这些客户被认为具有“高风险”生活方式因素，定义为以下两个或更多指标值较高：体重指数、血压、甘油三酯、肝酶和糖代谢。客户被随机分为三组：销售人员进行面对面（FF）干预组（n = 83）、通过社交网络服务进行非FF（Non-FF）干预组（n = 87）和无干预（对照组）（n = 58）。在所有组的3个月干预期前后进行尿液分析以及关于饮食和运动习惯的调查。对FF组和Non-FF组进行了三项干预，包括根据尿液分析结果提供饮食建议、鼓励减少盐摄入和增加运动活动的教育以及观看教育视频。对照组仅通过邮件收到他们的尿液分析结果。参与者的平均年龄为44.0岁。在Non-FF组中观察到估计钾摄入量有显著改善，在FF组和Non-FF组中均注意到尿Na/K比值有显著降低。多元逻辑回归分析表明，观看视频是降低尿Na/K比值最有效的因素（优势比 = 1.869）。根据问卷，观看视频的个体的饮食行为总分有显著改善。本研究证明了私人健康保险公司在促进健康方面的潜力，并引入了一种改善生活方式相关疾病高风险个体生活习惯的新策略。
