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 | |
| Baby | ||||
| 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.
