| Popis: | Summary Background We have completed a randomised clinical trial of breastfeeding and formula feeding to identify the frequency of breastmilk transmission of HIV-1 to infants. However, we also analysed data from this trial to examine the effect of breastfeeding on maternal death rates during 2 years after delivery. We report our findings from this secondary analysis. Methods Pregnant women attending four Nairobi city council clinics were offered HIV tests. At about 32 weeks' gestation, 425 HIV-1 seropositive women were randomly allocated to either breastfeed or formula feed their infants. After delivery, mother-infant pairs were followed up monthly during the first year and quarterly during the second year until death, or 2 years after delivery, or end of study Findings Mortality among mothers was higher in the breastfeeding group than in the formula group (18 vs 6 deaths, log rank test, p=0·009). The cumulative probability of maternal death at 24 months after delivery was 10·5% in the breastfeeding group and 3·8% in the formula group (p=0·02). The relative risk of death for breastfeeding mothers versus formula feeding mothers was 3·2 (95% CI 1·3–8·1, p=0·01). The attributable risk of maternal death due to breastfeeding was 69%. There was an association between maternal death and subsequent infant death, even after infant HIV-1 infection status was controlled for (relative risk 7·9, 95% CI 3·3–18·6, p Interpretation Our findings suggest that breastfeeding by HIV-1 infected women might result in adverse outcomes for both mother and infant. |
