This study was conducted to assess the impact of a nutrition education intervention on food groups and omega-3 (n-3) fatty acid consumption in middle-aged women. We hypothesized that participants who received educational materials about n-3 fatty acids would have a higher consumption of foods rich in n-3 fatty acids than the MyPyramid group. The first phase of this study used the qualitative method to identify the beliefs and interests of middle-aged women about the topic of nutrition. Data were collected using semistructured individual interviews. Phase 2 was a quantitative study to assess the effectiveness of MyPyramid to improve dietary intake and self-efficacy after a 6-week online nutrition education intervention using a blog for university middle-aged female staff. The impact of n-3 fatty acid education on food consumption and self-efficacy was also assessed. Eight female staff (aged 45-65 years) in a Midwestern university participated in the interviews. Data were coded, and 3 themes emerged: "health," "lifestyle," and "availability." Eighty-eight middle-aged women participated in the intervention study and were randomized into either an intervention group or a control group. The overall consumption of the food groups was lower than the MyPyramid recommendation, except in the meat and beans group. There was a trend that participants were less certain to include n-3 fatty acids than whole grains in their diets. Using MyPyramid and supplementary information about n-3 fatty acids did not significantly affect participants' dietary consumption or self-efficacy to increase consumption from the food groups or to increase n-3 fatty acid consumption. Blog-based nutrition education is acceptable for this target population.
这项研究旨在评估营养教育干预对中年女性食物组和ω-3(n-3)脂肪酸摄入的影响。我们假设,接受 n-3 脂肪酸教育材料的参与者,其 n-3 脂肪酸丰富食物的摄入量会高于 MyPyramid 组。本研究的第一阶段采用定性方法,以了解中年女性对营养主题的信念和兴趣。使用半结构化个人访谈收集数据。第二阶段是一项定量研究,评估 MyPyramid 在经过 6 周的在线营养教育干预后,通过博客对大学中年女性工作人员进行,以提高饮食摄入和自我效能。还评估了 n-3 脂肪酸教育对食物消费和自我效能的影响。在中西部一所大学的 8 名女性员工(年龄 45-65 岁)参加了访谈。对数据进行了编码,并出现了 3 个主题:“健康”、“生活方式”和“可获得性”。共有 88 名中年女性参加了干预研究,并被随机分为干预组或对照组。除了肉类和豆类组外,食物组的总体摄入量低于 MyPyramid 的建议。有一个趋势表明,参与者不太确定在饮食中包含 n-3 脂肪酸,而不是全谷物。使用 MyPyramid 和关于 n-3 脂肪酸的补充信息,并没有显著影响参与者的饮食消费或自我效能,以增加从食物组或增加 n-3 脂肪酸的消费。基于博客的营养教育是可以被这一目标人群接受的。
