7% had ever asthma; 46% of women identified as black and 53% had at least a college/technical school degree. A 2 μg/m higher PM exposure during the saccular phase was associated with 1.29 times higher risk of ever asthma (95% CI 1.06-1.58). A similar association was observed with current asthma (RR 1.27, 95% CI 1.04-1.54), but not current wheeze (RR 1.11, 95% CI 0.92-1.33). Effect estimates for associations during other developmental windows had confidence intervals that included the null. Later phases of prenatal lung development may
