FRIDAY, Feb. 3 (HealthDay News) -- Breast-feeding is associated
with improved lung function in school-age children, particularly
those with asthmatic mothers, a new study says.
Swiss and U.K. researchers analyzed data from nearly 1,500 U.K.
children who were born between 1993 and 1997. Questionnaires were
used to assess the duration of breast-feeding, other exposures, and
The children's lung function was measured when they were 12
Breast-fed kids overall had a "modest improvement" in forced
mid-expiratory flow (FEF50), which measures the amount and speed of
air that comes out of the lung during the middle portion of a
But breast-fed kids whose mothers also had asthma also did
better on two other lung function tests, forced vital capacity
(FVC) and forced expiratory volume at 1 second (FEV1), according to
Dr. Claudia Kuehni, a professor at the Institute of Social and
Preventive Medicine at the University of Bern in Switzerland.
"In contrast, some earlier studies have suggested that breastfeeding might be harmful in the offspring of mothers with asthma," she noted in a journal news release.
