Abstract

Background: Over the past decade there has been mounting evidence that ambient air pollution during pregnancy influences fetal growth. Objectives: This study was designed to examine possible associations between fetal ultrasonic measurements collected from 15,623 scans (13–26 weeks gestation) and ambient air pollution during early pregnancy. Methods: We calculated mothers’ average monthly exposures over the first 4 months of pregnancy for the following pollutants: particulate matter < 10 μm aerodynamic diameter (PM10), ozone, nitrogen dioxide, and sulfur dioxide. We examined associations with fetal femur length (FL), biparietal diameter (BPD), head circumference (HC), and abdominal circumference (AC). Final analyses included scans from only those women within 2 km of an air pollution monitoring site. We controlled for long-term trend, season, temperature, gestation, mother’s age, socioeconomic status, and fetal sex. Results: A reduction in fetal AC was associated with O3 during days 31–60 [−1.42 mm; 95% confidence interval (CI), −2.74 to −0.09], SO2 during days 61–90 (−1.67 mm; 95% CI, −2.94 to −0.40), and PM10 during days 91–120 (−0.78 mm; 95% CI, −1.49 to −0.08). Other results showed a reduction in BPD (−0.68 mm; 95% CI, −1.09 to −0.27) associated with SO2 during days 0–30, a reduction in HC (−1.02 mm; 95% CI, −1.78 to −0.26) associated with PM10 during days 91–120, and a reduction in FL associated with PM10 during days 0–30 (−0.28 mm; 95% CI, −0.48 to −0.08) and 91–120 (−0.23; 95% CI, −0.42 to −0.04). Conclusion: We found strong effects of ambient air pollution on ultrasound measures. Future research, including more individually detailed data, is needed to confirm our results.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
