Factors associated with mean birthweight and risk for low birthweight during antenatal survey, Guayaramerín and Bermejo, Bolivia, 2003–2004*

Characteristic Multiple linear regression, n = 329
Logistic regression, n = 329
Adjusted difference in mean birthweight, g (95% CI)† p value Adjusted OR for low birthweight (95% CI) p value
Mature 0 <0.001 1 NS
Premature –426 (−626 to −227) NS 10.5 (2.8–39.8) 0.001
Boy 0 NS NS 0.98
Girl –135 (−237 to −34) 0.009 NS 0.98
Multiparous mother 0 NS NS 0.52
Primiparous mother –181 (−287 to −75) 0.001 NS 0.52
No anemia at delivery 0 0.08 NS 0.69
Anemia at delivery – 92 (−195 to 10) 0.08 NS 0.69
Not infected at antenatal visits 0 NS 1 NS
Infected with Plasmodium vivax at antenatal visits – 266 (−453 to −78) 0.006 8.8 (2.4–32.5) 0.001

*OR, odds ratio; NS, not significant. Significant values (<0.05) are indicated in boldface. Multivariate models adjusting for mother’s age, maternal anemia, number of previous pregnancies, and sex and gestational age of the baby. Only significant variables (p<0.10) from the linear regression model are shown. The same variables were used for logistic regression model.
†Baseline mean birthweight was 3,538 g.
