大家好！
本周美国疾病预防控制中心《减盐电子周刊》包括以下内容：美国心脏协会（AHA）减钠工作、尿生物标志物最新研究，以及减少老年人膳食中钠含量的相关资源。
AHA的减钠工作
2013年6月，美国心脏协会（AHA）组织召开减钠会议，在为期两天的会议期间，近130多位来自各个领域的利益相关者齐聚一堂，讨论减少食品供应中钠含量的状况及未来影响，确定了合作机遇。会议论文报告《降低整体人口钠摄入量及减少食品供应中钠含量的利益相关者讨论》，近期发表于《循环（Circulation）》杂志，可点击下列链接阅读：http://circ.ahajournals.org/content/early/2014/05/05/CIR.0000000000000051.full.pdf+html。当选的美国心脏协会主席对减钠会议进行了讨论，可点击下列链接观看视频：https://www.youtube.com/watch?v=Iam3doKv7Lc。
此外，《循环》杂志近期发表了AHA与其他机构合著的论文，介绍了餐饮环境改善标准如何能使工作场所更加健康，回顾了全美模范标准，以及餐饮业各项重要标准中的共同因素。该论文题为《使工作环境更为健康的餐饮环境及采购政策》，可点击下列链接阅读：http://onlinelibrary.wiley.com/doi/10.1111/nure.12116/full。美国疾病预防控制中心（CDC）文件总结概述了众多与食品采购和食品服务准则有关的可用资源，可点击下列链接阅读：http://www.cdc.gov/salt/pdfs/salt_procurement_resources.pdf。
最新研究发现，过去20年中，尿钠排泄估计量增加
《营养学杂志》近期刊登论文《1988年至2010年间，美国成人尿钠排泄量略有增加》，文中采用随机尿样中的测定钠浓度，以年龄在20-59岁的美国成人的估计24小时尿钠（24hUNa）排泄为基线，评估了1988–2010的趋势。结果显示，20年研究期间，估计24hUNa排泄增加，研究作者认为，究其原因可能是因为身体质量指数（BMI）分布发生转变。
点击http://jn.nutrition.org/content/144/5/698阅读该研究。点击http://www.cdc.gov/salt/pdfs/sodium_reduction_biomarkers.pdf了解使用生物标志物数据来估算人口钠摄入量的当前科学研究。
减少老年人钠摄入的新资源
近期召开的 “百万份餐，百万颗心®：减少家庭送餐和集体订餐食物中钠含量” 网络会议，重点关注了减少老年人膳食中钠含量的重要性，讨论了如何在家庭送餐和集体订餐食物中实现国家对于钠摄入推荐量的目标，并进行专题案例研究，对“上门送餐服务计划”（Meals on Wheels program ）成功实施减钠策略进行了分析。会议还讨论了如何与食品分销商合作共同实现减钠目标。可点击下列链接了解该网络会议http://nutritionandaging.org/professional-developement/momentum-51064/topic-guide-million-hearts-for-millions-of-meals-reducing-sodium-in-home-delivered-and-congregate-meals。
www.cdc.gov/salt近期发布了两份相关资源。第一份资源题为“享受低钠美味”，目的是帮助老年人和护理人员，减少家庭烹饪和外出就餐时饮食中钠的含量。点击http://www.cdc.gov/salt/pdfs/sodium_tips_older_adults.pdf了解详细信息。第二份资源题为“减少集体订餐和家庭送餐食物中钠含量在线资源”，为减少老年人膳食中的钠含量提供了资源，如上门送餐服务计划（Meals on Wheels Program）和集体订餐服务，点击http://www.cdc.gov/salt/pdfs/sodium_resources_older_adults.pdf了解详细信息。
感谢您对减少钠摄入长期以来的关注和支持！

Hello –
This week’s CDC Salt e-Update includes AHA sodium reduction work, new research on urinary biomarkers, and resources for reducing sodium in meals served to older adults.
AHA Work on Sodium Reduction
In June 2013, the American Heart Association brought together nearly 130 multi-sector stakeholders via a two day Sodium Conference. Attendees discussed the status and future implications of reducing sodium in the food supply and identified opportunities for collaboration. The report of the Conference proceedings, entitled “Stakeholder Discussion to Reduce Population-Wide Sodium Intake and Decrease Sodium in the Food Supply” was recently published in Circulation and may be found here: http://circ.ahajournals.org/content/early/2014/05/05/CIR.0000000000000051.full.pdf+html. A video of American Heart Association President-Elect discussing the Sodium Conference may be found here: https://www.youtube.com/watch?v=Iam3doKv7Lc.
In addition, an AHA-coauthored paper recently published in the journal Nutrition Reviews describes how standards for improving food-and-beverage environments can create healthier worksites, reviews national model standards, and identifies common elements across standards that are important considerations when working in this area. The paper, entitled “Food-and-Beverage Environment and Procurement Policies for Healthier Work Environments” may be found here: http://onlinelibrary.wiley.com/doi/10.1111/nure.12116/full. A CDC document providing an overview of many available resources related to food procurement and food service guidelines may be found here: http://www.cdc.gov/salt/pdfs/salt_procurement_resources.pdf.
Estimated Urinary Sodium Excretion Has Increased Over the Past 20 Years, New Study Finds
A new paper published in the Journal of Nutrition, entitled “Urine Sodium Excretion Increased Slightly among U.S. Adults between 1988 and 2010,” assessed 1988–2010 trends in estimated 24-hour urine sodium (24hUNa) excretion among U.S. adults ages 20–59 years, using measured sodium concentrations in spot urine samples. Results indicate that estimated 24hUNa excretion increased over the 20-year study period, which may be due to a shift in the distribution of BMI, according to study authors.
The study may be found here: http://jn.nutrition.org/content/144/5/698. A resource document summarizing current science on using biomarker data to estimate population sodium intake may be found here: http://www.cdc.gov/salt/pdfs/sodium_reduction_biomarkers.pdf.
New Resources for Reducing Sodium in Older Adults
A recent webinar, entitled Million Hearts® for Millions of Meals: Reducing Sodium in Home Delivered and Congregate Meals, highlighted the importance of sodium reduction in meals served to older adults, discussed meeting national recommendations for sodium intake in home delivered and congregate meals, and featured a case study on successful implementation of sodium reduction strategies in the Meals on Wheels program. A discussion around working with food distributors on sodium reduction was also included. The webinar may be found here: http://nutritionandaging.org/professional-developement/momentum-51064/topic-guide-million-hearts-for-millions-of-meals-reducing-sodium-in-home-delivered-and-congregate-meals.
Related, two new resources were recently made available on www.cdc.gov/salt. The first, a Tips sheet entitled “Savor the Flavor with Less Sodium” can assist older adults and their caregivers with reducing sodium in the diet both through home cooking and when dining out, and may be found here: http://www.cdc.gov/salt/pdfs/sodium_tips_older_adults.pdf. The second, entitled “Online Resources for Reducing Sodium in Congregate and Home Delivered Meals” provides resources for reducing sodium in meals served for older adults, such as the Meals on Wheels Program and congregate meal services, and may be found here: http://www.cdc.gov/salt/pdfs/sodium_resources_older_adults.pdf.
Thank you for your continued engagement in sodium reduction.
