Allergy & Asthma Advocate: Summer 2007

Allergy & Ashtma Advocate
What's New in the JACI
The studies summarized below appeared in the Journal of Allergy and Clinical Immunology (JACI), the peer-reviewed scientific journal of the American Academy of Allergy, Asthma & Immunology.

Risk factor for developing atopy and asthma differ by child’s sex and parents history of allergy

The influence of breast-feeding on the development of allergies and asthma differs by a child’s sex and his/her parent’s history of allergy, according to a new study in the June 2007 issue of the Journal of Allergy and Clinical Immunology (JACI).

Piush J. Mandhane, MD, and colleagues examined asthma and atopy outcomes by sex, reported specific parental history of atopy, and breast-feeding.

The increase in risk of developing allergy and asthma associated with breastfeeding was most significant among those at lower baseline risk. Although further research is needed, based on these findings it may be important for doctors to inquire about the history of breastfeeding and parents’ history of allergy in analyzing risk factors for a child’s development of asthma and allergy. However, breastfeeding continues to be encouraged for its many other beneficial effects.


Difficulty in reading labels, a problem for food allergic people

A large number of food allergic adults have problems managing their food allergies because food labels used technical, unfamiliar or non-specific terms and because products do not consistently list new ingredients, according to a new study in the June 2007 issue of the Journal of Allergy and Clinical Immunology (JACI).

Food allergies among U.S. adults have become more prevalent in recent years. Because there are currently no cures for food allergies, individuals must manage their food allergies through avoidance of foods containing the allergens to which they are sensitive.

Katherine A. Vierk, MPH, and colleagues examined the prevalence of food allergies in U.S. adults and, specifically, their experiences with the use of food labeling. The authors analyzed data from the 2001 U.S. Food and Drug Administration’s Food Safety Survey of patients who reported having food allergy.

The researchers found that several of the label problems identified in this study are addressed by a new law, the Food Allergen Labeling and Consumer Protection Act of 2004, that became effective in January, 2006. The findings from this study can be compared with data collected later, after the effective date of the labeling change.
