Acetaminophen Linked to Childhood Asthma

For the study, researchers from the Arizona Respiratory Center collected data on 849 infants. After 22 years of follow-up, 181 people had asthma. The researchers found that children who had wheezing at age 6 or 7 were four times more likely to develop asthma as adults.

For children whose wheezing persisted, their risk of developing asthma increased 14 times. Other factors in childhood which increased the risk of asthma included low airway function (4.5 times increased risk for asthma) and bronchial responsiveness (7 times increased risk for asthma).

"In over 70 percent of people with current asthma and 63 percent of those with newly diagnosed asthma at age 22 years, episodes of wheezing had happened in the first three years of life or were reported by parents at age 6 years... Our findings support our previous proposition that most forms of asthma have their origins in early life, but we now extend that proposition to asthma diagnosed in early adult life," the authors concluded.
