The number of pregnant women with a body mass index (BMI) of 30kg/m(2) or more is increasing, which has important implications for antenatal care. Various resource-intensive interventions have attempted to assist women in managing their weight gain during pregnancy with limited success. A mobile phone app has been proposed as a convenient and cost-effective alternative to face-to-face interventions.
This paper describes the process of developing and pilot testing the Eating4Two app, which aims to provide women with a simple gestational weight gain (GWG) calculator, general dietary information, and the motivation to achieve a healthy weight gain during pregnancy.
The project involved the development of app components, including a graphing function that allows the user to record their weight throughout the pregnancy and to receive real-time feedback on weight gain progress and general information on antenatal nutrition. Stakeholder consultation was used to inform development. The app was pilot tested with 10 pregnant women using a mixed method approach via an online survey, 2 focus groups, and 1 individual interview.
The Eating4Two app took 7 months to develop and evaluate. It involved several disciplines--including nutrition and dietetics, midwifery, public health, and information technology--at the University of Canberra. Participants found the Eating4Two app to be a motivational tool but would have liked scales or other markers on the graph that demonstrated exact weight gain. They also liked the nutrition information; however, many felt it should be formatted in a more user friendly way.
The Eating4Two app was viewed by participants in our study as an innovative support system to help motivate healthy behaviors during pregnancy and as a credible resource for accessing nutrition-focused information. The feedback provided by participants will assist with refining the current prototype for use in a clinical intervention trial.
越来越多的孕妇体重指数（BMI）达到或超过 30kg/m(2)，这对产前护理有重要影响。各种资源密集型干预措施试图帮助孕妇在怀孕期间控制体重增加，但收效有限。有人提出使用手机应用程序作为面对面干预的替代方法，这种方法方便且具有成本效益。
本文介绍了开发和试点测试 Eating4Two 应用程序的过程，该应用程序旨在为女性提供一个简单的妊娠期体重增加（GWG）计算器、一般饮食信息以及实现健康妊娠体重增加的动力。
该项目涉及应用程序组件的开发，包括一个图表功能，允许用户记录整个怀孕期间的体重，并实时反馈体重增加进展和产前营养的一般信息。利益相关者咨询用于为开发提供信息。该应用程序通过在线调查、2 个焦点小组和 1 个个人访谈，对 10 名孕妇进行了试点测试，采用混合方法。
Eating4Two 应用程序的开发和评估耗时 7 个月。堪培拉大学涉及几个学科，包括营养与饮食学、助产、公共卫生和信息技术。参与者认为 Eating4Two 应用程序是一种激励工具，但希望图表上有可以显示确切体重增加的秤或其他标记。他们还喜欢营养信息，但许多人认为它应该以更用户友好的方式格式化。
在我们的研究中，参与者认为 Eating4Two 应用程序是一种创新的支持系统，可以帮助在怀孕期间激励健康行为，并为获取以营养为重点的信息提供可信资源。参与者提供的反馈将有助于改进当前原型，以用于临床干预试验。
