Surrounding greenness is associated with lower risk and burden of low birth weight in Iran

S. Luo, Y. Wang, et al.

This groundbreaking study reveals a significant link between prenatal greenspace exposure and low birth weight (LBW) in Iran, analyzing over 4 million live births. The authors found that enhancing greenspace could potentially prevent thousands of LBW births, underscoring the crucial health benefits of greenness, especially in low- and middle-income countries. Conducted by Siqi Luo, Yaqi Wang, Fatemeh Mayvaneh, Helder Relvas, Mohammad Baaghideh, Kai Wang, Yang Yuan, Zhouxin Yin, and Yunquan Zhang.

Abstract
This study investigated the association between prenatal greenspace exposure and low birth weight (LBW) in Iran using a nationwide retrospective cohort of 4,021,741 live births. Greenness exposure was assessed using satellite-based NDVI and EVI. Analyses revealed an L-shaped exposure-response relationship, with each 0.1-unit rise in NDVI/EVI associated with a 7.0–11.5% decline in LBW odds. Counterfactual analyses suggested that achieving greenness targets could avoid 3931–5099 LBW births (4.4–5.6% of the total). The findings highlight the potential health benefits of improved greenspace in reducing LBW risk and burden in low- and middle-income countries.
