Predictors of HIV infection in singleton infants exposed to HIV

	Unadjusted Odds Ratio (95% Confidence Interval)	P	Adjusted Odds Ratio (95% Confidence Interval)	P
No maternal ARV use	7.9 (2.1–30.2)	0.002	13.5 (2.5–72.1)	0.002
Preterm delivery	5.1 (1.4–19.4)	0.02	5.3 (1.1–25.1)	0.04
Intravenous drug use	5.2 (1.0–26.0)	0.04	4.3 (0.7–28.7)	0.1
Prenatal care	0.2 (0.03–0.9)	0.04	2.5 (0.3–20)*	0.4
Cesarean delivery	2.8 (0.6–13.5)	0.2
HIV RNA viral load > 1,000 copies/mL	2.6 (0.4–15.9)	0.3
Timing of maternal HIV diagnosis	1.4 (0.3–6.7)	0.7

Adjusted model, n= 560.

^*Prenatal care became a positive association in multivariate analysis. We believe this occurred because there were so few women in this category; there were zero women with an HIV infected infant who were not taking ARVs and did not receive PNC, but there were 2 women taking ARVs who did not receive prenatal care that had HIV-infected infant.
