Logistic Regression Using Generalized Estimating Equations for the Association of Prenatal Maternal Demoralization and Childhood Wheeze Through the Age of 5 Years

Predictor variable	OR (95% CI) for outcome of wheeze

	Univariate	Multivariate
Prenatal demoralization score	1.60 (1.24–2.06)	1.66 (1.29–2.14)
Mother’s age at pregnancy	0.99 (0.96–1.02)	1.01 (0.98–1.05)
Maternal ethnicity: African American vs Dominican	0.99 (0.69–1.41)	1.08 (0.74–1.57)
Maternal education at pregnancy
Less than high school vs some college	1.10 (0.73–1.66)	0.93 (0.61–1.43)
High school diploma vs some college	0.86 (0.57–1.31)	0.79 (0.51–1.21)
Maternal history of asthma (yes/no)	2.28 (1.62–3.23)	2.23 (1.55–3.21)
Maternal IgE (>100 vs ≤100 IU/mL)^a	1.14 (0.78–1.66)	0.96 (0.67–1.38)
Child exposed to secondhand smoke (yes/no)	1.16 (0.82–1.65)	1.00 (0.69–1.43)
Child of male sex vs. female	2.17 (1.56–3.01)	2.37 (1.69–3.30)
Wheeze within cold and flu season^b (yes/no)	1.72 (1.42–2.09)	1.77 (1.44–2.17)

Abbreviations: CI, confidence interval; OR, odds ratio.

For maternal IgE, a cut point of greater than 100 IU IgE/mL was used for analysis, as used previously.³²

Cold and influenza season was defined as symptoms occurring within September 1 to March 31.³⁰
