大家好！
本周的美国疾病预防与控制中心《减盐行动》电子周刊包含减钠方面的最新研究。
新西兰消费者报称对食品标签上的钠信息感到困惑
《公共健康营养》（Public Health Nutrition）杂志发表了一项2013年进行的研究。该研究的作者们就消费者对食品标签的知识和理解程度以及与钠摄入相关的食品购买行为进行了深入访谈。研究作者们通过对16位年龄介于28至63岁的新西兰成人的访谈结果进行分析，发现消费者缺乏理解和控制他们自身钠摄入的必要的背景知识，而且不能解释食品标签上有关钠的信息。研究作者们认为，有必要对新西兰消费者进行教育，让他们明白减钠对于健康的好处，并学会如何在饮食中减少钠摄入，包括学会理解食品标签上的信息。
该项研究题为《钠和营养标签：新西兰消费者食品购买行为的定性研究》，可通过以下链接找到：http://journals.cambridge.org/download.php?file=%2FPHN%2FPHN17_05%2FS1368980013001079a.pdf&code=b2a263e1732435b7892e95a86818a91c.
研究发现：高血压控制不佳的伊朗成人钠摄入量较高
2013年进行的一项横断面研究通过对671名年龄介于30至60岁、高血压控制良好和控制不佳的伊朗成人进行分析，发现高血压控制不佳的那组人的平均钠摄入量要比高血压控制良好的那组人高出一大截，两者分别为每天3599毫克和2654毫克。研究作者们向每位参与者发放了一个由四部分问题组成的问卷，来衡量他们对于与钠相关的知识和疾病的认知程度。研究作者们还通过参与者们3天的膳食记录收集了他们的钠摄入量情况。研究结果也表明，那些对于高钠摄入和疾病之间关联不太了解的人，其钠摄入水平比那些对这种关联比较了解的人要高。
该项研究题为《农村地区控制良好与控制不佳的高血压患者的钠摄入量、膳食知识及疾病认知》，发表在《国际高血压杂志》（International Journal of Hypertension）上，可通过以下链接找到：http://www.hindawi.com/journals/ijhy/2014/245480/.

Hello –
This week’s CDC Salt e-Update includes new research on sodium reduction.
New Zealand Consumers Report Confusion About Sodium Information on Food Labels
Authors of a 2013 study published in Public Health Nutrition conducted in-depth interviews exploring consumer knowledge and understanding of food labels and food purchasing behavior related to sodium intake. Authors analyzed findings from 16 New Zealand adults ages 28 to 63 years and found that consumers lack the background knowledge necessary to understand and control their own sodium intake, and are unable to interpret sodium information on food labels. According to study authors, there is a need to educate New Zealand consumers on the health benefits of sodium reduction and how to reduce sodium in their diets, including understanding food labels.
The study, “Sodium and Nutrition Labelling: A Qualitative Study Exploring New Zealand Consumers’ Food Purchasing Behaviours” may be found here: http://journals.cambridge.org/download.php?file=%2FPHN%2FPHN17_05%2FS1368980013001079a.pdf&code=b2a263e1732435b7892e95a86818a91c.
Iranian Adults with Uncontrolled Hypertension Have Higher Sodium Intake, Study Finds
Results of a 2013 cross-sectional study of 671 Iranian adults between 30 and 60 years of age with controlled and uncontrolled hypertension found that average sodium intake was significantly greater in the uncontrolled group compared to the controlled group; 3,599 mg and 2,654 mg per day, respectively. Study authors administered a four-part questionnaire to measure participant's knowledge and illness perceptions related to sodium, and sodium intake was collected via 3-day food records. Results also indicate that sodium intake was greater in those with poor knowledge and understanding of the association of high sodium intake and illness compared to those with better knowledge and understanding.
The study, entitled “Sodium Intake, Dietary Knowledge, and Illness Perceptions of Controlled and Uncontrolled Rural Hypertensive Patients” and published in the International Journal of Hypertension, may be found here: http://www.hindawi.com/journals/ijhy/2014/245480/.
Thank you for your continued engagement in sodium reduction.
