Poor housing conditions in adolescence and adult health outcomes: an outcome-wide longitudinal approach.

Background: While prior literature has documented the impact of housing quality on health, the long-lasting effects of poor housing conditions in adolescence on adult health remain understudied. This study employs an outcome-wide longitudinal approach to estimate the association between poor housing conditions in adolescence and a set of health outcomes in adulthood.

Methods: Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a large-scale, nationally representative sample of US adolescents, were used. This study analysed 15 health outcomes encompassing physical and mental/cognitive health, and health behaviours. The Bonferroni correction was applied to adjust the significance level of multiple testing of the associations.

Results: After applying the Bonferroni correction, poor housing conditions in adolescence were associated with seven adult health outcomes. These conditions were particularly strongly and robustly linked to mental health issues, including depression, suicidal ideation and perceived stress. Additionally, poor housing conditions were related to physical health outcomes such as cardiovascular disease risk and self-rated health, as well as health behaviours such as smoking and unhealthy eating behaviour.

Conclusion: Poor housing conditions during adolescence can act as an early risk factor for adult health, particularly mental health. These findings support the adoption of a life course approach and strengthen the case for housing interventions aimed at improving health outcomes.
