Health researchers and practitioners increasingly recognise the important role communities play in shaping individual health. Health researchers recognise the role of community factors as causes or determinants of health problems; use community-based methods for understanding complex health issues; and design community-level health solutions. In this commentary, we propose a fourth way to think about the role of communities in individual health by arguing that the community engagement process itself has implications for individual health and strong communities. This topic is especially important during adolescence, a developmental window of opportunity during which individuals need meaningful opportunities to contribute to the world around them.
