社区环境中膳食钠降低试验的评价。基于社区的随机试验。在注册营养师的监督下，进行为期10周的营养干预活动，重点是改变生活方式以减少膳食钠的摄入量。在基线和随访时收集24小时尿液标本，测定24小时尿钠排泄量。匹兹堡大学健康老龄化中心，生命营养关键项目。65岁以上的高血压患者。参与者的平均年龄为75岁。24小时基线平均尿钠排泄量为3174 mg/d。在6个月和12个月的随访中分别降至2944 mg/d （P = 0.30）和2875 mg/d （P≤0.03）。在亚样本（尿量≥1000 ml，基线至12个月）中，平均尿钠排泄量从3220 mg/d降至2875 mg/d （P≤0.02）。据报道，平均24小时尿钠显著降低，但结果低于高危人群推荐的1500毫克/天的指导值。我们的结果重申了在以社区为基础的方案中执行这些指导方针的困难。需要更积极的公共卫生努力、食品工业的支持和卫生政策的改变来将老年人的钠水平降低到推荐的指导水平。
Evaluation of a dietary Na reduction trial in a community setting. Community-based randomized trial. Ten-week nutrition intervention activities focused on lifestyle modification to decrease dietary Na intake, under the supervision of a registered dietitian. Twenty-four hour urine specimens were collected at baseline and follow-up visits to determine 24 h urinary Na excretion. The University of Pittsburgh Center for Healthy Aging, Key to Life Nutrition Program. Hypertensive adults at least 65 years of age. Mean age of participants was 75 years. Twenty-four hour mean urinary Na excretion at baseline was 3174 mg/d. This reduced to 2944 mg/d (P = 0·30) and 2875 mg/d (P ≤ 0·03) at 6-and 12-month follow-ups, respectively. In a sub-sample (urine volume of ≥ 1000 ml, baseline to 12 months), mean urinary Na excretion decreased from 3220 mg/d to 2875 mg/d (P ≤ 0·02). Significant reductions in mean 24 h urinary Na were reported, but results fell short of the recommended guidelines of 1500 mg/d for at-risk individuals. Our results reiterate the difficulty in implementing these guidelines in community-based programmes. More aggressive public health efforts, food industry support and health policy changes are needed to decrease Na levels in older adults to the recommended guidelines.
