Acute effects of air pollutants on spontaneous pregnancy loss: a case-crossover study.

ABSTRACT:

Objective

To investigate the relationship between acute exposure to air pollutants and spontaneous pregnancy loss.

Design

Case-crossover study from 2007 to 2015.

Setting

An academic emergency department in the Wasatch Front area of Utah.

Patient(s)

A total of 1,398 women who experienced spontaneous pregnancy loss events.

Intervention(s)

None.

Main outcome measure(s)

Odds of spontaneous pregnancy loss.

Result(s)

We found that a 10-ppb increase in 7-day average levels of nitrogen dioxide was associated with a 16% increase in the odds of spontaneous pregnancy loss (odds ratio [OR] = 1.16; 95% confidence interval [CI] 1.01-1.33; P=.04). A 10-μg/m³ increase in 3-day and 7-day averages of fine particulate matter were associated with in
