背景：农村地区成年女性肥胖率较高。尽管农村人口被认为很难接触到，但随着农村互联网接入的增加，基于互联网的编程正在成为一种可行的策略。然而，当人们能够上网时，他们可能找不到为他们和他们的需求设计的信息，尤其难以接触到人群。这导致了许多用户的“内容鸿沟”。目的：以用户为中心的设计是一种可以用来创建合适的在线材料的方法。本研究旨在应用以用户为中心的方法，为居住在马里兰州农村的低收入母亲设计和开发一个健康促进网站。方法：进行了三轮反复的概念测试，以(1)确定网站的名称和内容需求，并评估在健康相关网站上注册的担忧；(2)确定网站的基调和外观，确认内容和功能；(3)确定可用性和可接受性。前两轮包括焦点小组和小组讨论，第三轮包括对使用原型系统的女性进行可用性测试。结果：形成性研究显示，收入有限的女性对提供营养和体育活动信息的网站很感兴趣，这些信息针对她们的收入，并根据她们的个人目标和需求量身定制。确定的其他优先内容领域包括预算编制、当地资源和信息以及可与子女一起使用的内容。女性能够有效地使用原型系统。结论：本研究表明，以用户为中心的设计策略可以帮助风险受众缩小“内容差距”。
Background: Adult women living in rural areas have high rates of obesity. Although rural populations have been deemed hard to reach, Internet-based programming is becoming a viable strategy as rural Internet access increases. However, when people are able to get online, they may not find information designed for them and their needs, especially harder to reach populations. This results in a "content gap" for many users.Objective: User-centered design is a methodology that can be used to create appropriate online materials. This research was conducted to apply a user-centered approach to the design and development of a health promotion website for low-income mothers living in rural Maryland.Methods: Three iterative rounds of concept testing were conducted to (1) identify the name and content needs of the site and assess concerns about registering on a health-related website; (2) determine the tone and look of the website and confirm content and functionality; and (3) determine usability and acceptability. The first two rounds involved focus group and small group discussions, and the third round involved usability testing with individual women as they used the prototype system.Results: The formative research revealed that women with limited incomes were enthusiastic about a website providing nutrition and physical activity information targeted to their incomes and tailored to their personal goals and needs. Other priority content areas identified were budgeting, local resources and information, and content that could be used with their children. Women were able to use the prototype system effectively.Conclusions: This research demonstrated that user-centered design strategies can help close the "content gap" for at-risk audiences.
