Factors associated with mean hemoglobin level and risk for moderate-to-severe anemia, excluding Plasmodium falciparum infections, during hospital-based survey, Guayaramerín and Bermejo, Bolivia, 2002–2004*

Characteristic Multiple linear regression, n = 1,439 Logistic regression, n = 1,439
Adjusted difference in mean hemoglobin level, g/dL (95% CI)† p value Adjusted OR for moderate-to-severe anemia (95% CI) p value
Primiparous mother 0 NS NS 0.23
Multiparous mother –0.28 (−0.51 to −0.06) 0.012 NS NS
Bermejo 0 NS NS 0.42
Guayaramerín –0.38 (−0.59 to −0.16) 0.001 NS NS
Noninfected placenta 0 NS 1 NS
P. vivax– infected placenta –0.70 (−1.32 to −0.09) 0.026 2.5 (1.04–6.2) 0.04

*OR, odds ratio; NS, not significant. Significant values (<0.05) are indicated in boldface. Multivariate models adjusting for number of previous pregnancies, antenatal visits, houses with indoor insecticide spraying, site of study, and delivery during transmission season. Only significant variables (p<0.10) from the linear regression model are shown. The same variables were used for the logistic regression model.
†Baseline mean hemoglobin level was 11.7 g/dL.
