Information and communication technology increasingly addresses the information needs patients have regarding their personal health. While an understanding of older adults' needs is crucial for developing successful eHealth technology, user research results hardly apply to different systems.
The present study aims at: (1) describing and analysing the context of digital health systems in a general manner, (2) investigating if information need of older adults influences their technology usage to show the relevance of the concept for a general context analysis and (3) testing which demographic variables intervene with their health information need.
Survey data from a longitudinal study with older adults (N = 551) were reported descriptively. After showing a significant relationship during chi-square tests, we quantified the ones between general health information need and technology usage, as well as between general health information need and the demographic variables age, education, chronic diseases and gender by means of (multiple) linear regression models.
We predicted older adults' technology usage based on their health information need. The results confirmed this relationship. Higher information need led to a more frequent usage of apps installed on the tablet personal computer (PC), to a frequent use of smartwatches and to the possession of a computer or laptop. Users' education has a higher impact on health information need than amount of chronic diseases, gender and age.
Information need emerged as a useful object for investigation of context and user requirement analysis across different systems: it predicted technology usage so that design recommendations derived from the descriptive gained in importance.
信息通信技术越来越多地满足患者对个人健康信息的需求。虽然了解老年人的需求对于开发成功的电子健康技术至关重要，但用户研究结果几乎不适用于不同的系统。
本研究旨在：（1）以一般方式描述和分析数字健康系统的背景，（2）调查老年人的信息需求是否会影响他们的技术使用情况，以显示该概念在一般背景分析中的相关性，以及（3）测试哪些人口统计学变量会干预他们的健康信息需求。
对一项针对老年人（N = 551）的纵向研究的调查数据进行描述性报告。在卡方检验显示出显著关系后，我们通过（多元）线性回归模型量化了一般健康信息需求与技术使用之间的关系，以及一般健康信息需求与人口统计学变量年龄、教育程度、慢性病和性别之间的关系。
我们根据老年人的健康信息需求预测了他们的技术使用情况。结果证实了这种关系。更高的信息需求导致更频繁地使用安装在平板电脑个人电脑（PC）上的应用程序，更频繁地使用智能手表以及拥有计算机或笔记本电脑。用户的教育程度对健康信息需求的影响高于慢性病数量、性别和年龄。
信息需求成为跨不同系统进行背景和用户需求分析的有用调查对象：它预测了技术使用情况，因此从描述中得出的设计建议变得更加重要。
