Associations of PM_2.5 and its components with term preterm rupture of membranes: a retrospective study.

ABSTRACT:

Background

There is evidence that fine particulate matter (PM_2.5) exposure is associated with premature rupture of membranes (PROM); however, studies of its effect on term PROM (TPROM) are limited, and the results are inconsistent.

Objective

This study aimed to investigate the association between exposure to PM_2.5 and its components and the risk of TPROM.

Methods

From 2018 to 2022, we collected delivery data from pregnant women in Guangzhou. Using 1:1 case matching, we included 1,216 TPROM cases and 1,216 controls. PM_2.5 and its component concentrations were obtained from Tracking Air Pollution in China. The time-varying mean concentration method was used to estimate exposure to PM_2.5 and its components during different trim
