Youth with moderate FI had a relative risk (RR) of 1.37 (95% CI 1.32–1.41) for poor mental health, and those with severe FI had an RR of 1.60 (95% CI 1.54–1.66), compared to none/mild FI, after adjustment for sociodemographic covariates. Stratified analyses showed the association persisted across all 19 UN sub-regions and across income levels.

ABSTRACT

Food insecurity (FI) represents a major global health challenge. Because climate-related disasters are a determinant of both FI and poor mental health, we investigated whether the severity of these disasters intensifies the relationship between FI and youth mental health. Data on FI and mental health came from the Gallup World Poll, a nationally representative survey of individuals in 142 countries, which included 28,292 youth aged 15–24. Data on climate-related disasters came from the International Disaster Database, a country-level record of disasters. Multilevel negative binomial regression was used to calculate relative risk (RR) of poor mental health. Youth with moderate or severe FI were significantly more likely to report poor mental health experiences compared to those with none/mild FI (moderate: RR 1.37, 95% confidence interval (CI) 1.32–1.41; severe: 1.60, 95% CI 1.54–1.66). We also observed a weak yet significant interaction effect (p<0.0001), which suggested that the country-level relationship between FI and poor mental health is slightly stronger at greater disaster severity. While further research is needed to improve our understanding of these complex relationships, these findings suggest that mental health should be considered when undertaking national climate change actions and that additional FI-related supports may work to improve youth mental health.
