We study real-world health complexities among young adults. The health and social issues that arise during this life period affect not only the individual but also their families, their workplaces, and may have long-lasting effects on later health and social trajectories. However, the causes and consequences of these health and social issues are intertwined, complex, and often understudied; thus, fundamental questions related to the health and social issues experienced by young adults remain unanswered. By illuminating the distinct patterns and characteristics of the health and social issues in this age group, we aim to address the underlying dynamics that contribute to these problems.
