The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) differs from other federal nutrition programs in that nutrition education is a required component. WIC programs traditionally provide in-person education, but recently some WIC sites have started offering online education. Education focused on reducing salt intake is an important topic for WIC participants because a high-sodium diet has been associated with high blood pressure, and low-income populations are at increased risk.
Our aim was to examine the impacts of traditional in-person and online nutrition education on changes in knowledge, self-efficacy, and behaviors related to reducing salt intake in low-income women enrolled in WIC.
Although a comparison of groups was not the primary focus, a randomized trial examining the impact of online and in-person nutrition education on participant knowledge, self-efficacy, and behaviors related to salt intake was conducted.
PARTICIPANTS/SETTING: Five hundred fourteen WIC participants from three Los Angeles, CA, WIC clinics received either in-person (n=257) or online (n=257) education. Questionnaires assessing salt-related knowledge, self-efficacy, and behaviors were administered at baseline and 2 to 4 months and 9 months later from November 2014 through October 2015.
Positive changes in knowledge and self-efficacy were retained 2 to 4 months and 9 months later for both groups (P<0.05). Both groups reported significant changes in behaviors related to using less salt in cooking (P<0.0001) and eating fewer foods with salt added at the table or during cooking (P<0.001) at 2 to 4 months and 9 months.
Both online and in-person education resulted in improvements during a 9-month period in knowledge, self-efficacy, and reported behaviors associated with reducing salt intake in a low-income population. Offering an online education option for WIC participants could broaden the reach of nutrition education and lead to long-term positive dietary changes.
妇女、婴儿和儿童特殊补充营养计划(WIC)与其他联邦营养计划的不同之处在于,营养教育是其必需组成部分。WIC计划传统上提供面对面教育,但最近一些WIC站点已开始提供在线教育。关注减少盐摄入量的教育对WIC参与者而言是一个重要主题,因为高钠饮食与高血压相关,且低收入人群风险更高。
我们的目标是研究传统面对面和在线营养教育对参加WIC的低收入女性在减少盐摄入量相关知识、自我效能和行为变化方面的影响。
尽管组间比较并非主要重点,但开展了一项随机试验,以研究在线和面对面营养教育对参与者与盐摄入量相关的知识、自我效能和行为的影响。
参与者/地点:来自加利福尼亚州洛杉矶市三家WIC诊所的514名WIC参与者接受了面对面(n = 257)或在线(n = 257)教育。在2014年11月至2015年10月期间,于基线、2至4个月以及9个月后进行了评估与盐相关知识、自我效能和行为的问卷调查。
两组在2至4个月和9个月后知识和自我效能均保持积极变化(P < 0.05)。两组均报告在2至4个月和9个月时,与烹饪中少用盐(P < 0.0001)以及少吃在餐桌上或烹饪时添加了盐的食物(P < 0.001)相关的行为有显著变化。
在9个月期间,在线和面对面教育均使低收入人群在与减少盐摄入量相关的知识、自我效能和报告行为方面有所改善。为WIC参与者提供在线教育选项可以扩大营养教育的覆盖范围,并带来长期积极的饮食变化。
