Expanding our knowledge of wealth's role in shaping adolescents' current and long-term health is of critical public health concern, especially as wealth is more unequally distributed than income. This review discusses what is known about wealth-related inequalities in adolescent physical health and proposes four psychosocial mechanisms that may explain how wealth shapes adolescent physical health including (1) serving as a stress-buffer; (2) enabling parents to invest in opportunities to support adolescent healthy development; (3) increasing families' access to social and cultural capital resources that may promote salutary health behaviours while mitigating experiences of social-class discrimination; (4) and supporting adolescents' future expectations.

Many patients stop taking a new medication soon after they are prescribed it, often not collecting the medication. Early patterns of nonadherence are linked to later nonadherence via processes such as habit formation and symptom experiences. Known predictors of nonadherence may be present before someone starts a new treatment, when patients experience disruption to their lives and identity due to illness. Healthcare professionals typically have contact with patients around this time. We argue that it may be possible to prevent medication nonadherence: at the population level; by optimising the prescription process; and through low- and high-intensity interventions for patients with identified early barriers.
