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.
