Association of gestational weight gain rate (100 g/week) (n = 915), and BMI/MUAC at enrolment (n = 1947), with birthweight
| Univariable regression | Multivariable regression | |||||
|---|---|---|---|---|---|---|
| Coefficient | (95% CI) | P | Coefficient | (95% CI) | P | |
| Gestational weight gain (100 g/week) | 21.0 | (9.0, 33.0) | 0.001 | 14.0* | (2.6, 25.4) | 0.016 |
| Enrolment MUAC (cm) | 37.8 | (29.7, 45.9) | <0.001 | 29.1 † | (21.1, 37.0) | <0.001 |
| Enrolment BMI (kg m−2) | 31.3 | (24.0, 38.6) | <0.001 | 30.2 | (23.1, 37.3) | <0.001 |
| Height (cm) | 16.5 | (12.9, 20.1) | <0.001 | 13.2 † | (9.7, 16.7) | <0.001 |
Note: Coefficient denotes change in birthweight in grams associated with a 1 U increment of the predictor variable. All adjusted analyses include age, gravidity, treatment arm, timing of birthweight measurement and newborn sex as covariates. *Additionally adjusted for height and MUAC. †Additionally adjusted for height or MUAC.
