We analysed infant feeding cumulatively from birth to 5 months using 24‐hour feeding history (collected weekly for each of the preceding 7 days). Using generalised estimating equation mixed models, allowing for repeated measures, we compared postpartum weight change (kg) from the first maternal postpartum weight within the first 6 weeks (baseline weight) to each subsequent visit through 24 months among 2340 HIV‐infected and ‐uninfected women with live births and at least two postpartum weight measurements.</p> </sec> <sec id="tmi12320-sec-0003" sec-type="section"> <title>Results</title> <p>HIV‐infected (−0.2 kg CI: −1.7 to 1.3 kg; <italic>P </italic>=<italic> </italic>0.81) and ‐uninfected women (−0.5 kg; 95% CI: −2.1 to 1.2 kg; <italic>P </italic>=<italic> </italic>0.58) had marginal non‐significant weight loss from baseline to 24 months postpartum. Adjusting for HIV status, socio‐demographic, pregnancy‐related and infant factors, 5‐month feeding modality was not significantly associated with postpartum weight change: weight change by 24 months postpartum, compared to the change in the reference EBF group, was 0.03 kg in NBF (95% CI: −2.5 to +2.5 kg; <italic>P </italic>=<italic> </italic>0.90) and 0.1 kg in MF (95% CI: −3.0 to +3.2 kg; <italic>P </italic>=<italic> </italic>0.78).</p> </sec> <sec id="tmi12320-sec-0004" sec-type="section"> <title>Conclusion</title> <p>HIV‐infected and ‐uninfected women experienced similar weight loss over 24 months.
