Correlation between exposure to fine particulate matter and hypertensive disorders of pregnancy in Shanghai, China.

ABSTRACT:

Background

Association between fine particulate matter (PM_2.5) and hypertensive disorders of pregnancy (HDP) is inconsistent and appears to change in each trimester. We aim to investigate the association of exposure to ambient PM_2.5 in early pregnancy with HDP.

Methods

A retrospective cohort study was performed among 8776 women with singleton pregnancy who attended the antenatal clinic before 20 gestational weeks in a tertiary women's hospital during 2014-2015. Land use regression models were used to predict individual levels of PM_2.5 exposure.

Results

The average PM_2.5 concentration during the first 20 gestational weeks ranged from 28.6 to 74.8 μg m^- 3 [median, 51.4 μg m^- 3; interquartile range, 47.3-5
