Researchers wanted to know if treating eczema early and consistently in infants could change their chances of developing other allergies later on. They followed 590 children from a previous study. Half had received early, proactive eczema treatment until they were 28 weeks old, while the other half received standard, reactive treatment.
At age three, the group that got the early, proactive treatment had a lower rate of doctor-diagnosed food allergy. For example, about 47% of children in that group had any food allergy, compared to about 59% in the standard care group. The study also found a lower rate of egg allergy and one type of pollen sensitivity at age two, but not for other allergies like asthma or rhinitis.
The main reason to be careful is that the differences between the groups were small. The researchers note that the results might be due to both groups getting good overall eczema care and early diagnosis, not just the specific treatment plan. This study suggests that managing infant eczema well might be one part of a strategy to reduce later food allergies, but it is not a guarantee and more research is needed.
