Ethics in infant formula research


“If the connection, say between formula milk early feeding and later obesity really is as established as researchers such as Lucas claim (see paper in the book), then public policy might adopt some very restrictive policies.  Instead of simply instructing health visitors to encourage young mothers to breast feed, they might forbid the sale of formula milk without a prescription, provide serious tax incentives for young mothers to breastfeed (an thus penalize young mothers who do not), or seek to stigmatise or even criminalize formula feeding for young babies.  But, of course, such draconian measures would seriously conflict with the ethos of many liberal, democratic societies and endanger individual rights.”  By Irene Cetin & Robin Gill from the chapter entitled, “Ethical Issues in Perinatal Nutrition Research,” in the 2005 book, “Early Nutrition and Its Later Consequences:  New Opportunities,” edited by Berthold Koletzko https://link.springer.com/chapter/10.1007/1-4020-3535-7_1

The editor, Berthold Koletzko, is on the scientific advisory board of the Family Larsson & Rosencrist Foundation, well known editor for many Nestle Nutrition Institute Workshop Series edited the above book which was funded by Danone.

One of my Facebook friends, Magdalena Whoolery, a member of IBFAN alerted me to a recent research paper. The research paper is published in PLOS, with grants from the Bill & Melinda Gates Foundation and the US National Institute of Health (NIH).  I tried to comment to the article, but either there is a wait system regarding comments, or some kind of computer glitch (my own or theirs) it has yet to be published.  So I thought I would comment here on this proposed research endeavor on low birth weight babies in 2 African Nations (Guinea Bissau and Uganda).

The research paper states that they support exclusive breastfeeding, but their proposal for this research is to introduce infant formula in the early days as a preventative to possible future malnutrition.  We have at least 40 years of research that shows the importance of exclusive breastfeeding for all babies, in order to prevent diarrhea (a know risk for death in infants) and various diseases that exclusive breastfeeding can prevent or mitigate those diseases.  The authors state, “…early, daily, small volume supplementation supported growth without interfering with overall breastfeeding duration.”  This statement was cited to footnotes #20 and #21. Those two studies are studies that one of the co-authors to the current study (Valerie Flaherman) is also listed as a co-author. 

In the two studies done in the United States, exclusively breastfed, full-term infants were given 10mL of formula by syringe after every breastfeed.  This current study will be done in 2 African nations on exclusively breastfed, low birth weight infants.  They will be given 59mL of infant formula after breastfeeding by bottles and sterilized nipples.

It has been known for some time that the early introduction of bottles/bottle nipples/teats can in some babies result in those babies refusing the breast and preferring bottles.  A care giver does not know which baby will have this particular problem, and it would seem to be a matter of logic to refrain from the introduction of bottles and bottle nipples/teats for as long as possible so that one does not interfere with exclusive breastfeeding in the early weeks.

The authors state the study will be conducted under the principles of the 2008 Declaration of Helsinki.  There is a more up-to-date Declaration of Helsinki, published  in 2013. One of the principles listed in the 2008 Declaration states, “The health of my patient will be my first consideration.” (#4) and, “Some research populations are particularly vulnerable and need special protection. They include those who cannot give or refuse consent themselves…” (9)  Babies cannot give consent to be part of an experiment, they are one of the most vulnerable in need of protection.   Babies who receive infant formula in the early days, may have short and long term health consequences like obesity, diabetes, and other unknown consequences.  And mothers who end up weaning early, may also suffer health consequences, such as a greater likelihood of breast and ovarian cancers, heart disease, and the emotional loss of closeness to their babies.

The authors state that they are, “…conservatively estimating a 20% loss to follow-up.’  Follow-up is very important and when the estimate seems to possibly be quite high, I would think that the authors may want to reconsider their approach.  The Declaration of Helsinki principle #33 states, “At the conclusion of the study, patients entered into the study are entitled to be informed about the outcome of the study..”  How will this research be able to follow the Declaration, if their estimate for follow-up is “conservatively a 20% loss?
