Bridging the Gap: How Health Tech Can Fight Inequality

A world where health advice is as personalized as a Netflix recommendation. Health recommender systems (HRS) are stepping into the game as an emerging field in digital health. These smarts systems assess information from multiple layers of influence that shape our habits and decisions about health. We are talking about our family, friends, community, and even our local government and their policies! These systems are full of potential to play a huge role in fighting health inequality. The socioecological model has a lot to offer by illustrating how various levels of influence-from communities to policies-shapes our health. It's a complex web, but HRS can help tailor health advice that addresses not just individual health factors but also the real-world barriers, like access to healthcare and healthy food. By combining user preferences with additional data about social determinants of health, HRS can tackle systemic challenges that hinder good health. People from low socioeconomic status and racial/ethnic minorities could benefit the most from these systems. However, some might say, current HRS are not up to the task. They often overlook the lived experiences of users and tend to focus more on individual health behaviors rather than the big picture. To truly make a difference, a shift in the design paradigm of HRS is crucial. They should prioritize health systems and embed decolonial perspectives of well-being. This approach challenges conventional medical models. But, do we know the full extent of HRS' impact on health equity? By evaluating the health equity effects of HRS, we can learn more and advocate for policy changes. Furthermore, by intentionally focusing on equity, HRS could significantly boost health promotion by making real changes in practices. We have all the tools to make it happen! Still, the current design paradigm has some loopholes and challenges. The reach and effectiveness of HRS for people of low socio-economic status and racial or ethnic minorities remain a concern. HRS tend to prioritize user preferences, but we also need to address structural barriers for true progress. Simply put, with targeted improvements, HRS could revolutionize health promotion and mitigate health inequality. But, there is a long road ahead. New research priorities and a deliberate focus on health equity could steer HRS in the right direction, transforming them into a powerful tool for change.
