Hattevig G, Sigurs N, Kjellman. Effects of maternal dietary avoidance during lactation on allergy in children at 10 years of age. Acta Paediatrica, 88: 7-12, 1999.

In order to reduce the risk of food allergy in children, mothers are sometimes advised to avoid eating certain foods during lactation. In a 10 year follow-up study researchers in Sweden studied the rate of allergies in children whose mothers had followed different eating regimes during lacation. In one group the mothers had not eaten eggs, cow's milk or fish during the first three months of lactation. In the other group the mothers had not restrictied their diets.

Results showed that a high rate of allergic symptoms occurred in both groups. However, there was no significant difference between the two groups. This was true for both food and inhaled allergens. Also there was no difference in the immunoglobin E levels in the blood of the children in the two groups. It was concluded that the results did not support the general recommendation to avoid allergy-causing foods during lacation.

Morrow AL, Guerrero ML, Shults J, Calva JJ, Lutter C, Bravo J, Ruiz-Palacios G, Morrow RC, Butterfoss FD. Efficacy of home-based peer counselling to promote exclusive breastfeeding: a randomised controlled trial, The Lancet: 353: 1226-1231, 1999.

Exclusive breastfeeding for about 6 months is the optimal method of infant feeding. However, it is uncommon even in cultures of high breastfeeding rates. In order to assess the effect of peer counselling on the rates of exclusive breastfeeding, researchers in Mexico City carried out a study in which mothers were randomly assigned to groups with different frequency of peer counselling. One group received three counselling visits, another received 6 visits and the control group had no visits. Counselling for pregnant women consisted of the benefits of breastfeeding, positioning, problems and solutions. Counselling of new mothers included establishing a good breastfeeding pattern, maternal concerns, and providing information and social support.

Results showed that at 3 months after birth 67% of mothers of the 6 visit group, 50% of the 3 visit group and 12% of the control group were exclusively breastfeeding. Increased duration of any breastfeeding was also seen in the visited groups at 6 months with 87% visited mothers still breastfeeding versus 76% of the control group. Another outcome of the study showed that the control group of infants had twice as many episodes of diarrhea compared with the visited group.

Howard C, Howard F, Lawrence R, Andresen E, DeBlieck E. Office prenatal formula advertising and its effect on breastfeeding patterns, Obstetrics and Gynecology, 95: 296-303, 2000.

Researchers in Rochester, New York, USA compared the effect of prenatal distribution of baby food industry-sponsored educational packs with non-commercial educational packs on mothers' infant feeding choices. The distribution of promotional material and formula samples to families is prohibited by the International Code of Marketing of Breast-milk Substitutes. The results of the study of 547 mothers showed that a mother's choice to breastfeed or bottle-feed was not affected by the type of educational materials she received before the birth of her baby. 61% of mothers had already decided to breastfeed before pregnancy while 11% changed their minds during pregnancy. However, receiving commercially-sponsored packs did affect breastfeeding duration. These packs contained a baby milk company nappy bag, educational materials, a can of infant fomula and a business reply card. The non-commercial packs contained a generic nappy bag, non-commercial educational material about pregnancy, and a $5 coupon for baby items. Both groups of mothers were offered help with breastfeeding concerns.

By the end of the second week after birth 24% of the mothers who had received commercial packs stopped breastfeeding while only 15% of mothers who had received non-commercial materials had stopped. Mothers who had received commercial packs were five times more likely to stop breastfeeding in hospital.

Gupta A, Khanna K. Economic value of breastfeeding in India, The National Medical Journal of India, 12(3):123-127, 1999.

Breastmilk is an important national resource and breastfeeding saves health care costs. Two doctors in India calculated the value of breastmilk and breastfeeding for this country of 24.4 million annual births. Based on the national breastfeeding patterns they calculated that over the usual 2 year lactation period mothers produced a total of 3944 million liters of breastmilk. If this milk were to be replaced by tinned cow's milk it would cost $3 billion. This amount is three times more than the government spending for the Departments of Education, Health and Family Welfare, and Science and Technology. At the household level the cost of artificially feeding an infant is 43% of the minimum wage of a skilled urban worker.

With regards to the reduction of health care costs by breastfeeding, increasing breastfeeding could save $180 million by reducing episodes of diarrhea. Saving from reduction of acute otitis media costs would be $131 million if breastfeeding was increased. Breastfeeding also leads to lower fertility. At current rates in India breastfeeding saves $123.7 million in contraception costs.

Rea MA, Venancio SI, Martines JC, Savage F. Counselling on breastfeeding: assessing knowledge and skills, Bulletin of the World Health Organization, 77: 492-498, 1999.

Health care workers have an important role to play in supporting mothers' decision to continue to breastfeed or to introduce breast-milk substitutes. WHO and UNICEF have developed several counselling courses to teach heath workers appropriate knowledge and skills. In order to analyze the effectiveness of the WHO course, Breastfeeding counselling: a training course, researchers carried out a randomized study of 60 health professionals in Sao Paulo, Brazil. One group followed the course which included training in theoretical and clinical aspects of breastfeeding, listening skills, helpful non-verbal communication, empathizing, building confidence and giving practical help among other skills. The second group did not follow the course. The knowledge level and quality of counselling skills of both groups was tested before and after the course. Three months later a further evaluation was given to the course group.

The results showed that out of a possible score of 10 for breastfeeding knowledge the course group scored an average of 8.35 and the control group 6.23. Post-course testing also showed that the course significantly improved counselling skills. Three months later testing showed that the level of knowledge and skills were maintained at a high level.
