Feeding soya-based formula as opposed to st and ard cow 's milk formula did not reduce the risk of having asthma or wheeze at any age .
In infants with at least one first degree relative with atopy , hydrolysed formula for a minimum of 4 months combined with dietary restrictions and environment measures may reduce the risk of developing asthma or wheeze in the first year of life .
There is insufficient evidence to suggest that soya-based milk formula has any benefit
BACKGROUND In infants with a family history of atopy , food allergen avoidance has been advocated as means of preventing the development of atopic disease when breast-feeding is not possible or supplemental feeding is needed .
Most infant formulas are based on cow 's milk protein .
Alternative choices include soya based and hydrolysed cows milk formulas .
OBJECTIVES To estimate the effect of dietary avoidance of cow 's milk protein on the development of asthma or wheeze in children .
Extensively and partially hydrolysed infant formulas for allergy prophylaxis
The allergy preventive effect of extensively ( N ) and partially ( PH ) hydrolysed cows ’ milk formulas compared with a regular formula ( RM ) was assessed in 155 infants with a family history of allergy . No cows ’ milk was given during the first nine months of life and no egg and fish  up to 12 months of age . Breast feeding mothers avoided the same foods . At weaning the infants were r and omised to one of the formula groups . The cumulative incidence of atopic symptoms at 18 months was 51 , 64 , and 84 % in the N , PH , and RM groups , respectively . From 6 to 18 months there were significantly less cumulative atopic symptoms in the N group compared with the RM group , and significantly less than the PH group up to 6 ( N = 25 % ; PH = 46 % ) and 9 months ( N = 34 % , PH = 58 % ) . At 9 months significantly fewer infants in the N group ( 10 % ) than in the PH group ( 33 % ) had a positive skin prick test to eggs . The findings support an allergy preventive effect of an extensively hydrolysed formula , but not of a partially hydrolysed formula , during the first 18 months of life of high risk infants
