BACKGROUND Infant formulas containing hydrolysed proteins have been widely advocated for preventing allergic disease in infants , in place of st and ard cow 's milk formula ( CMF ) .

OBJECTIVES To compare effects on allergic disease when infants are fed a hydrolysed formula versus CMF or human breast milk .
If hydrolysed formulas are effective , to determine what type of hydrolysed formula is most effective , including extensively or partially hydrolysed formula ( EHF/PHF ) .
To determine whether infants at low or high risk of allergic disease , and whether infants receiving early short-term ( first few days after birth ) or prolonged formula feeding benefit from hydrolysed formulas .
Effect of exclusive breast-feeding and early solid food avoidance on the incidence of atopic dermatitis in high-risk infants at 1 year of age.
The aim of this study was to assess the preventive effect of exclusive breast-feeding and early solid food avoidance on  atopic dermatitis ( AD ) in infancy . This study is part of a dietary clinical trial in a prospect i ve cohort of healthy term newborns at risk of atopy . It was recommended to breast-feed for at least 4 months and to avoid solid food in the same time-period . Eight hundred and sixty-five infants exclusively breast-fed , and 256 infants partially or exclusively formula-fed , were followed-up until the end of the first year following birth . AD and sensitization to milk and egg were considered as study end-points . The 1-year incidence of AD was compared between the two study groups . Adjusted odds ratios ( OR ) with 95 % confidence intervals ( CI ) were calculated by multiple logistic regression . The incidence of AD was calculated in relation to age at introduction of solid food and amount of food given . In the breast-fed group , the adjusted OR for AD was 0.47 ( 95 % CI 0.30 - 0.74 ) . The strongest risk factor was the occurrence of AD in the subject 's core family . The risk of infants with AD to be sensitized to milk was four times higher , and to egg eight times higher , than in infants without AD . Age at first introduction of solid food and diversity of solid food showed no effect on AD incidence . We conclude that in infants at atopic risk , exclusive breast-feeding for at least 4 months is effective in preventing AD in the first year of life
