Abstract
OBJECTIVE: Rapid digitisation of health occurred during the COVID-19 pandemic worldwide. In October 2020, we conducted a survey on digital health technology use in Germany. This study aimed to conduct a second survey to investigate in more detail the internet use in health context and digital technology use for health promotion and disease prevention in Germany. METHODS: A cross-sectional, nationwide telephone survey was conducted in November 2022. Anonymous data on internet and digital technology use, digital health literacy, and sociodemographic characteristics were analysed using descriptive statistics and binary logistic regressions. RESULTS: The 1020 participants were aged 18-92 years, 53% were male, 62% completed primary or secondary education, 71% resided in large cities, and 45% reported a country-average net household income. Overall, 61% reported internet use in health context via 1-4 devices. Among those, more than 50% used the internet and apps to obtain general health information and less than 50% used digital technologies for physical activity promotion or cancer prevention. Overall, 34% were confident in using the internet for health decisions and 71% preferred to receive health information non-digitally (e.g. on paper). Internet, app, and digital technology use were associated with higher digital health literacy and income, and residence in larger cities. Digital technologies were used for physical activity promotion by younger and for cancer prevention by older participants. CONCLUSION: The internet and digital technologies were predominantly used to obtain health information, but less often for health promotion and disease prevention in 2022 in Germany. While health app and digital technology use for physical activity promotion increased, the confidence in using online information for health decisions decreased in 2022 relative to 2020. Factors that promote confidence in online health information and digital technology use for health promotion and disease prevention need to be investigated in future studies.
