Appendix B

Appendix B presents a compilation of abstracts of studies that address relationships of the mode of infant feeding with the infant's subsequent survival in developing countries. Abstracts are presented in either tabular or narrative form and are arranged chronologically.

e NR = Not reported.

COMMENTS: Deaths for partially breastfed infants were not presented. Diarrhea increased with the initiation of supplemental foods among breastfed infants in 11 villages in Punjab, India, from 1955 to 1959. "No deaths occurred among cases in the immediate weaning period; fatalities occurred in cases of the late post weaning period. … The explanation would appear to be in the nutritional state of the child" (Gordon et al., 1963, p. 368).

b Age period to which the feeding method applies.

COMMENTS: Neither death rates of nonbreastfed infants nor numbers of breastfed infants were presented. Effects were much smaller in households with a toilet and piped water. The authors' conclusion of a declining association of breastfeeding and mortality with age is not obviously supported by the data presented. The same data set was used by Holland (1987) and Millman and Cooksey (1987). The data do not allow estimation of relative risks.

ABSTRACT B-15 Schmidt (1983) reported on a collaborative study among urban poor in eight Latin American countries and Portugal involving 7,659 children in 1981 and 1982. The infant mortality rate for formula-fed infants was 18.6/1,000 live births, but the results were not presented in a form that allows calculation of mortality rates for those infants who were breastfed or mixed fed or for those whose feeding method was unknown. Furthermore, results were not stratified by site or age of child. The group that was breastfed only was probably much younger (and more susceptible to higher death rates) than the weaned group.

ABSTRACT B-19 Barros and colleagues (1982) conducted a study involving all 5,914 births in the hospital in Pelotas, Brazil, in 1982. The children were followed up at age 2 years. Of the infants born weighing less than 2,000 g, 42% were never breastfed (compared with less than 10% of all others). The children who were small at birth were also more likely to be weaned. The authors reported that even if breastfeeding (either partial or exclusive) had no protective effect, nonbreastfed babies appeared to be at 30% increased risk of death. The duration of breastfeeding was unrelated to birth weight in the highest two (of five) socioeconomic groups.

COMMENTS: Results are open to circularity: death could cause a shorter period of breastfeeding. It is unclear to what age death rates refer and how infants less than age 3 years at the time of the survey were handled in the analysis.

c Child-months refers to the number of months of observation summed across all children.

d Relative risk for breastfed infants = 1.0.

e Cannot be estimated.

COMMENTS: An effect was observed only among those with the smallest arm circumferences. Incidence of diarrhea was not affected, but the case fatality rate was higher among weaned children. The possibility of a spurious association of diarrhea causing weaning was ruled out.

On the basis of a comprehensive literature review and analysis, Nutrition During Lactation points out specific directions for needed research in understanding the relationship between the nutrition of healthy mothers and the outcomes of lactation. Of widest interest are the committee's clear-cut recommendations for mothers and health care providers.

The volume presents data on who among U.S. mothers is breastfeeding, a critical evaluation of methods for assessing the nutritional status of lactating women, and an analysis of how to relate the mother's nutrition to the volume and composition of the milk.

Available data on the links between a mother's nutrition and the nutrition and growth of her infant and current information on the risk of transmission through breastfeeding of allergic diseases, environmental toxins, and certain viruses (including the HIV virus) are included. Nutrition During Lactation also studies the effects of maternal cigarette smoking, drug use, and alcohol consumption.
