Infants’ characteristics at birth
| HIV uninfected (n = 92) | Reference (n=65) | Mean Δ (SE) | p value | |
|---|---|---|---|---|
| Mean (SD) gestational age (weeks) | 39.2 (1.3) | 39.2 (1.4) | −0.01 (0.22) | 0.93 |
| Mean (SD) weight for age z score | −0.29 (1.16) | −0.03 (1.03) | −0.26 (0.18) | 0.14 |
| Mean (SD) length for age z score | −0.31 (0.96) | −0.04 (0.92) | −0.27 (0.15) | 0.07 |
| Mean (SD) weight for length z score1-150 | −0.42 (0.80) | −0.35 (0.58) | −0.07 (0.13) | 0.58 |
| Sex (M/F) | 53/39 | 35/30 | 0.63 | |
| Parity (1st/> 1st) | 72/20 | 42/23 | 0.05 |
Mean (SE) differences of continuous variables (Δ) between the HIV uninfected and the reference groups (SE of 95% CI).
↵1-150 Weight for length z scores at birth have been calculated for 66 HIV uninfected cases and 45 reference cases as standardised data were unavailable for lengths < 49 cm.
