Children allergic to cow’s milk are smaller and lighter according to study

Analyzing the growth trajectories of children allergic to cow’s milk and comparing them with those of non-allergic children, an allergist at the Children’s National Hospital concluded that allergic children are smaller in build and weigh less than those with other types of allergies such as peanut nut allergies. These physical characteristics can persist until early adolescence.

The longitudinal study was published in the Journal of Allergy and Clinical Immunology and was produced by the researcher Karen A. Robbins, of the division of allergies and immunology of the aforementioned hospital, who points out that at the moment it is not yet clear whether these growth trends then influence definitively also the height levels of children will reach once they become adults.
However, the same researcher adds that these results “are in line with recent research suggesting that young adults with persistent cow’s milk allergy may not reach their full growth potential.

Milk allergy, like other food allergies, is difficult to treat and can persist for life. This means that the affected person eliminates what can be considered an important contribution to their diet.

The researcher analyzed data from 191 children between the ages of 2 and 12 years of age, 111 of whom had cow’s milk allergy and 80 nut allergy.  In addition to differences in weight, the researcher noted a more pronounced height discrepancy between 5 and 8 years of age and between 9 and 12 years of age. And for 53 of the subjects when they were 13 years old, these differences in weight and height were even more pronounced.

The same researcher adds: “Because these children often have multiple food allergies and other conditions, such as asthma, there are probably other factors other than giving up cow’s milk that can contribute to these results. These children also tend to limit food intake beyond cow’s milk.”
