Digital Divide – Soziale Unterschiede in der Nutzung digitaler Gesundheitsangebote

Today, health inequalities are one of the most important issues in public health worldwide. The digitalisation of healthcare is frequently attributed with the potential to reduce health inequalities. At the same time, effective internet usage is a prerequisite of the successful utilisation of digital health interventions. This might be a new obstacle for those who lack the necessary material resources or individual skills.Evidence on how exactly digital health interventions affect health inequalities is scarce. The aim of this study was to present a narrative review of the available literature. The majority of studies showed an association between the usage of digital health interventions and sociodemographic factors. The utilisation was generally higher among younger people and those with higher education and higher income. Only few studies showed no association. Other studies reported higher utilisation among those with higher levels of health literacy while health literacy showed a social gradient to the disadvantage of those in lower socioeconomic position. With a low overall level of evidence, there is currently no indication that digital health interventions are reducing health inequalities.The studies analysed in this review indicate that existing inequalities persist in the digital realm. Further evidence is needed to create a better understanding of the importance of sociodemographic factors for digital health interventions.
