The short-term effect of ozone on pregnancy loss modified by temperature: Findings from a nationwide epidemiological study in the contiguous United States.

ABSTRACT:

Background

Pregnancy loss, a major health issue that affects human sustainability, has been linked to short-term exposure to ground-surface ozone (O₃). However, the association is inconsistent, possibly because of the co-occurrence of O₃ and heat episodes, as increased temperature is a risk factor for pregnancy loss. To explain this inconsistency, the effect of O₃ on pregnancy loss needs to be examined jointly with that of high temperature.

Methods

A total of 247,305 pregnancy losses during the warm season were extracted from fetal death certificates from the 386 counties in contiguous United States from 1989 to 2005. We assessed environmental exposure based on the daily maximum 8 h average of O₃ from Air Quality System monitors an
