Ambient air pollution and the risk of pregnancy loss: a prospective cohort study.

ABSTRACT:

Objective

To estimate the association of pregnancy loss with common air pollutant exposure. Ambient air pollution exposure has been linked to adverse pregnancy outcomes, but few studies have investigated its relationship with pregnancy loss.

Design

Prospective cohort study.

Setting

Not applicable.

Patient(s)

A total of 343 singleton pregnancies in a multisite prospective cohort study with detailed protocols for ovulation and pregnancy testing.

Intervention(s)

None.

Main outcome measure(s)

Timing of incident pregnancy loss (from ovulation).

Result(s)

The incidence of pregnancy loss was 28% (n = 98). Pollutant levels at women's residences were estimated using modified Community Multiscale Air Quality models and averaged during the past 2 week
