Abstract

fetched live from OpenAlex

INTRODUCTION: Green spaces and blue spaces associate positively with mental health outcomes. However, research on their effects within the perinatal population is limited. The unique needs and circumstances of this group and their increased risk for poor mental health underscore the importance of understanding their relationship with their immediate physical environments. The current study investigates how proximity to green spaces and blue spaces relate to perinatal depression and anxiety symptoms and if the strength of this relationship varies over the perinatal period (prenatal, and 3, 6, 12, & 24 months postpartum). METHODS: Green (NDVI, tree canopy) and blue space (distance from the nearest water body) measures from the Canadian Urban Environmental Health Research Consortium were linked to depression (Edinburgh Postnatal Depression Scale) and anxiety (Patient-Reported Outcomes Measurement Information System) data from the pan-Canadian Pregnancy during the COVID-19 Pandemic (PdP; n = 10,866) cohort study. RESULTS: Greater NDVI (-0.91 (-1.77, -0.05) and shorter distance to water bodies (-0.14 (-0.24, -0.03)) were associated with fewer perinatal depression symptoms. On probing interactions with time, the relationship between tree canopy and NDVI varied over time for both depression and anxiety symptoms, with strongest associations at the prenatal time point. Effects of distance to water bodies did not vary over time. CONCLUSION: Green spaces and blue spaces were associated with fewer perinatal depression and anxiety symptoms, particularly during pregnancy. These findings suggest the need for studies to determine if exposure to green and blue spaces can contribute to reduced depression and anxiety symptoms in expectant individuals.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
