Factors associated with mean birthweight and risk for low birthweight babies, excluding Plasmodium falciparum infections, during hospital-based survey, Guayaramerín and Bermejo, Bolivia, 2002–2004*

Characteristic Multiple linear regression, n = 1,417
Mutlivariate logistic regression, n = 1,417
Adjusted difference in mean birthweight, g (95% CI)† p value Adjusted OR for low birthweight (95% CI) p value

*OR, odds ratio; NS, not significant. Significant values (<0.05) are indicated in boldface. Multivariate models adjusting for mother’s age, number of previous pregnancies, antenatal visits, houses with indoor insecticide spraying, site of study, delivery during transmission season, mother’s anemia, and sex and gestational age of the baby. Only significant variables (p<0.10) from linear regression model are shown. The same variables were used for the logistic regression model.
†Baseline mean birthweight was 3,537 g.
‡First and second pregnancies combined compared with multiparous women.
