Newborn babies living near green spaces tend to be healthier: study
- Researchers at Drexel University's Dornsife School of Public Health found in 2025 that newborns near newly planted trees in Portland, Oregon, tend to have higher birth weights.
- The study used data on over 36,000 trees planted between 1990 and 2020, measuring trees within 100 meters of a mother's home and controlling for factors like pregnancy order.
- They observed a statistically significant increase of 2.3 grams per tree planted and that living near at least 10 trees was linked to about a 50-gram birthweight increase.
- Professor Yvonne Michael explained that even a small increase of 50 grams in newborn weight across the study group could lead to a significant reduction—specifically, 642 fewer infants being classified as small for their gestational age, which is linked to developmental risks later on.
- The findings suggest that planting trees is a practical, low-cost method to improve infant health, although established trees may also provide additional benefits like air pollution reduction.

Newborn babies living near green spaces tend to be healthier: study
Researchers found that green spaces were associated with higher birth weight, lower risk of small-for-gestational-age birth and decreased risk of pre-term birth.
La nature comme stratégie de santé publique en ville
L’espèce humaine est devenue une espèce urbaine, avec 58% de la population mondiale qui vit en ville et près de 70% d’ici 2050. Au pays, 3 Canadiens sur 4 (74,8%) vivent en milieu urbain. Parallèlement, la nature est bonne pour la santé des êtres humains, concluent de plus en plus d’études scientifiques. Devant ces constatations, des universitaires se proposent d’aider les municipalités à ramener plus de nature en ville comme stratégie de santé …
