A total of 605 mother- child dyads from the PROGRESS cohort were included in this study. Table 1 shows the distribution of exposure, outcomes, and covariates of the study population as a whole and then stratified by child sex. Child sex was evenly distributed within this population. The average maternal age was 27 years of age. The majority of participants had a lower SES (52%), and no more than a high school education (40%). Only 8 women reported ever having asthma at enrollment. Prenatal depression were observed in 16% of mothers, postpartum depression in 25% of mothers, and recurrent depression in 17% of mothers. Overall, at the 48 month assessment 26%, 13%, and 3% of the children had a caregiver report ever wheeze, current wheeze, and asthma, respectively. The distribution of respiratory outcomes in children at 72 months were as follows: a) ever wheeze in 16%, b) current wheeze in 6%, and c) asthma in 4%. Additionally, overall 29% of the study participant’s caregivers reported any ever wheeze, 14% any current wheeze, and 5% ever asthma.
