Spot urine samples with estimating equations have been used to assess individuals' sodium (salt) intake in association with health outcomes. There is large random and systematic error in estimating sodium intake using this method and spurious health outcome associations. Substantial controversy has resulted from false claims the method is valid. Hence, the World Hypertension League, International Society of Hypertension and Resolve to Save Lives, supported by 21 other health organizations, have issued this policy statement that strongly recommends that research using spot urine samples with estimating equations to assess individuals' sodium (salt) intake in association with health outcomes should not be conducted, funded or published. Literature reviews on the health impacts of reducing dietary sodium that include studies that have used spot and short duration timed urine samples with estimating equations need to explicitly acknowledge that the method is not recommended to be used and is associated with spurious health outcome associations.
采用估计方程的随机尿样已被用于评估个体的钠(盐)摄入量与健康结果之间的关系。使用这种方法估计钠摄入量存在很大的随机和系统误差,以及虚假的健康结果相关性。由于该方法被虚假声称是有效的,因此引起了很大的争议。因此,世界高血压联盟、国际高血压学会和拯救生命决心组织,在 21 个其他健康组织的支持下,发布了这项政策声明,强烈建议不要进行、资助或发表使用估计方程的随机尿样来评估个体的钠(盐)摄入量与健康结果之间关系的研究。包含使用估计方程的随机和短期时间尿样的关于减少饮食钠对健康影响的文献综述需要明确承认,不建议使用该方法,并且与虚假的健康结果相关性相关。
