Research Roundup: The Latest Medical News for People With Allergies and Food Sensitivities
Babies whose mothers have allergies or asthma may be at increased risk for wheezing between 6 and 18 months if they participate in baby swimming at six months, finds a study done in Norway through the Norwegian Institute of Public Health. Previous studies on the effects of swimming in infancy have been inconclusive, and so researchers analyzed data collected from 30,000 mothers and children for the Norwegian Mother and Child Study. The investigators found that about 25 percent of babies were swimming at the age of 6 months. The prevalence of lower respiratory tract infection (LRTI) among swimmers was 13 percent; wheezing, 40 percent; and middle ear infection, 30 percent. Baby swimmers in general were not more likely than non-swimmers to have LRTI, to wheeze or to have otitis media. Swimmers with moms who had allergies or asthma had a higher risk of wheezing, but not of LRTI or ear infection.
