This study examines the association of urban residential tree canopy cover with perceived stress in a cohort of pregnant women in Philadelphia, PA, and explore whether this association differed among participants with a history of anxiety and depression. Highlights found: Residential tree canopy cover is associated with lower prenatal stress among women with anxiety or depression; 100 m buffers are more sensitive than 500 m in detecting stress-greenness associations and, evaluating stress-greenness associations should take into account mental health history.
