Objective: To examine infant feeding intentions of HIV-infected and uninfected women and the appropriateness of their choices according to their home resources; and to determine their adherence to their intentions in the first postnatal week. Methods: Feeding intentions of pregnant women were compared against four resources that facilitate replacement feeding: clean water, adequate fuel, access to a refrigerator and regular maternal income. First-week feeding practices were documented. Findings: The antenatal feeding intentions of 1253 HIV-infected women were: exclusive breastfeeding 73%; replacement feeding 9%; undecided 18%. Three percent had access to all four resources, of whom 23% chose replacement feeding. Of those choosing replacement feeding, 8% had access to all four resources. A clean water supply and regular maternal income were independently associated with intention to replacement feed (adjusted odds ratio (AOR) 1.94, 95% confidence interval (CI) 1.2-3.2; AOR 2.1, 95% CI: 1.2-3.5, respectively). Significantly more HIV-infected women intending to exclusively breastfeed, rather than replacement feed, adhered to their intention in week one (exclusive breastfeeding 78%; replacement feeding 42%; P < 0.001). Of 1238 HIV-uninfected women, 82% intended to exclusively breastfeed; 2% to replacement feed; and 16% were undecided. Seventy-five percent who intended to exclusively breastfeed adhered to this intention postnatally, and only 11 infants (< 1%) received no breast milk. The number of antenatal home visits significantly influenced adherence to feeding intention. Conclusion: Most HIV-infected women did not have the resources for safe replacement feeding, instead choosing appropriately to exclusively breastfeed. Adherence to feeding intention among HIV-infected women was higher in those who chose to exclusively breastfeed than to replacement feed. With appropriate counselling and support, spillover of suboptimal feeding practices to HIV-negative women is minimal.
Pregnant women attending seven rural clinics, one semi-urban clinic and one urban clinic in KwaZulu Natal, South Africa, were offered confidential HIV counselling and testing as part of a cohort study investigating breastfeeding and MTCT. From August 2001 to June 2003 all HIV-infected, and a subsample of uninfected, women were offered enrolment in the study. From July 2003 all women attending antenatal clinics were offered enrolment before HIV testing. After post-test counselling, HIV-infected women were offered a further infant feeding counselling session one to two weeks later. HIV and infant feeding counselling were provided by lay staff who had completed 12 years of schooling and were selected after assessment of literacy, numeracy and basic counselling skills. Their initial training included an HIV counselling course (two weeks), a WHO/UNICEF breastfeeding counselling course (five days),14 and a WHO/UNICEF HIV and infant feeding counselling course (three days).5 Free commercial infant formula for HIV-infected women was not available initially, but was provided by the KwaZulu Natal provincial prevention of mother-to-child transmission (PMTCT) programme starting in December 2002. Personal details including age, past pregnancies, education, water supply, sanitation, access to a refrigerator and income were recorded antenatally. Feeding intentions were compared against four resources considered necessary for safe replacement feeding: access to clean water, a refrigerator, fuel for boiling water (electricity, gas or paraffin) and a regular maternal income. The latter was used as a proxy for a woman’s ability to control financial resources in the household, particularly important in this area where few couples cohabit because of high levels of migration.15,16 Pregnancy outcomes and feeding practices in the first week of life were collected during home visits. Data were captured using optical imaging recognition software (Teleform V7.1, Cardiff Inc., San Diego, CA, USA) in a Microsoft SQL server database. Analyses were carried out using SPSS version 12 (SPSS Inc., Chicago, IL, USA). Univariable and multivariable logistic regression analyses were used to obtain unadjusted and adjusted odds ratios (AOR) and 95% confidence intervals (CIs). The study was approved by the ethics committee of the University of KwaZulu Natal, Durban, South Africa. Pregnant women who were HIV uninfected, or of unknown serostatus, were given information about exclusive breastfeeding for the first six months of the infant’s life, with sustained breastfeeding thereafter. HIV-infected women were counselled on different feeding options available to them. We developed an algorithm for the counsellors to use when presenting infant feeding choices to an HIV-infected woman (Fig. 1). The approach considers the woman’s feeding intention and explores the appropriateness of this based on her home circumstances. Her choice is discussed to understand what she means by breastfeeding and replacement feeding, i.e. whether her choice is based on previous experience or family preferences, whether breastfeeding would be mixed or exclusive, and how long she planned to use this feeding method. Finally, the feasibility of the woman’s intention is explored, focusing on home circumstances, past experiences, family expectations and likelihood of disclosure of HIV status at home. If the woman’s intention seems consistent with her circumstances, the counsellor affirms the woman’s intention, but also mentions that there are options that other women may choose. If the woman’s circumstances do not favour her intention, or a better practice may be feasible, e.g. the woman has the conditions for giving replacement feeding safely, then the counsellor discusses these options in more detail. Counselling algorithm on infant feeding choices for use by lay HIV counsellors After counselling at the clinic, all women received one antenatal home visit by a breastfeeding counsellor (blinded to HIV status) to discuss study logistics and to support the woman in her feeding option. Those choosing replacement feeding were referred to the project infant feeding specialist for a home visit to demonstrate safe replacement feeding preparation. Women who chose to breastfeed received up to three further antenatal home visits (up to four sessions) by the lay breastfeeding counsellor. If a woman changed her mind about her feeding choice antenatally, her intention nearest to the time of delivery was used for analysis. Strict WHO feeding definitions were applied throughout this study.5 Exclusive breastfeeding means an infant receives only breast milk and no other liquids or solids, not even water, with the exception of drops or syrups consisting of vitamins, mineral supplements or medicines.
