in comparison to the breastfeeding group, the formula
feeding group had more women progressing to WHO stage
3 (4 vs. 0).
On longitudinal analysis using GLM adjusting for
baseline age, CD4 and BMI, there were no significant
differences between groups except for the breastfeeding
group having significantly fewer events of SRQ20 scores
being C8 (P = 0.043).
Examining the effect of breastfeeding on the growth of
infants we found that the breastfeeding infants had significantly higher mean measurements for all parameters
except length and head circumference and the corresponding z scores at 14 weeks; this was no longer significant at 6 or 9 months (Table 3; Figs. 1, 2).
All the above parameters were analysed further using
GEE adjusted for follow-up time, mother’s BMI, CD4
count, and socio-economic conditions.
