Allergies are often blamed on many things. A new study adds birth order to the list of possible reasons for being prone to allergies. The study, published in Parents magazine, claims older children are likely to suffer more allergies than younger children. Food allergies tend to be more prevalent than other types of allergies among older children, according to the study.
The study found food allergies occurred 4 percent of the time in the participants in the research project who were firstborn children. The rate decreased to 3.5 percent for those born second and dropped to 2.6 percent for subsequent children.
Thirteen thousand children, from 7 through 15, were involved in the study. Kara Corridan of Parents magazine called the findings preliminary. Corridan adds the findings may provide some comfort to parents. The study suggests pregnancies after the first may build up an immunity against some allergies in the womb.
