目的开发基于Android手机/平板的24小时膳食回顾调查软件,为膳食调查数据采集提供新方法。方法基于美国国家健康与营养研究调查(National Health and Nutrition Examination Survey,NHANES)和欧洲癌症与营养前瞻性调查软件(the European Prospective Investigation into Cancer and Nutrition Software Program,EPIC-SOFT)开发原理,根据我国24小时膳食回顾调查实际,运用新一代计算机技术开发适合我国国情的24小时膳食回顾调查软件。结果以一万多行代码开发了方便实用具有中国特色的24小时膳食回顾调查软件,实现了24小时膳食回顾调查的电子化操作。结论使用24小时膳食回顾调查软件代替纸质调查问卷,不但可节省时间,减轻调查人员的操作工作量,更重要的是利用先进的计算机技术可提高调查质量。这一技术不但可用于食品安全研究,也可用于营养学调查。
Objective To develop a 24-hour meal review software based on Android mobile phone / tablet, which provides a new method for data collection of dietary survey. Methods Based on the principles developed by the National Health and Nutrition Examination Survey (NHANES) and the European Prospective Investigation into Cancer and Nutrition Software Program (EPIC-SOFT) Hour review of the actual diet, the use of a new generation of computer technology to develop suitable for China’s national 24-hour diet review survey software. Results A convenient and practical 24-hour dietary recall survey software with Chinese characteristics was developed with more than 10,000 lines of code to realize the electronic operation of a 24-hour dietary recall survey. Conclusion The use of the 24-hour meal-recall survey software instead of the paper-based questionnaire not only saves time and reduces the workload of investigators, but more importantly, uses advanced computer technology to improve the quality of the investigation. This technology can be used not only for food safety research but also for nutrition research.
