Abstract
Poor mental health outcomes among young people, including anxiety, depression, and suicide, have increased substantially in recent years. Given this concerning rise, more research into low-cost mental health interventions is needed. Research suggests that greenspace may be protective of mental health. This study aims to further understanding of the greenspace-mental health association among young people in five distinct urbanities (i.e., urban, suburban, micropolitan, small towns, rural/isolated). We apply publicly available greenspace datasets, which were used to derive greenspace quantity, quality, and accessibility metrics. Emergency department visits for young people (< 24 years) for the following mental health disorders were examined: anxiety, depression, mood disorders, mental and behavioral disorders, and substance use disorders. Generalized linear models investigated the association between greenspace and community-level drivers of mental health burden in North Carolina. Mood disorders saw the highest increase in prevalence in urban communities with low greenspace quantity (PRR: 1.19, CI: 1.16–1.21), anxiety disorders were associated with the greatest increase in rural/isolated communities with poor greenspace quality (PRR: 1.61, CI: 1.43–1.82), and both substance use disorders (PRR: 2.38, CI: 2.19–2.58) and depression (PRR: 2.09, CI: 1.72–2.53) were associated with the greatest increase in prevalence in rural/isolated communities with poor greenspace accessibility. Greenspace quantity interventions may be most effective in urban and suburban areas, greenspace quality interventions may be most beneficial in small towns and rural/isolated communities, and greenspace accessibility interventions may be most useful in urban, micropolitan and rural/isolated communities. Our analysis provides community-specific findings to guide targeted greenspace-mental health interventions.
