Using data from the European Community Health Survey, researchers at The National Institute of Health and Medical Research in France divided the subjects into four groups: those with rhinitis, with allergies, with both or neither.
The subjects were tracked over nearly a nine year period. Only one percent of the group that had neither ailment developed asthma, and almost twice as many of the allergy sufferers did.
More than three percent of adults with chronic runny noses wound up with asthma, and the rate jumped to nearly four percent for those who previously had both rhinitis and allergies.
A third study from the same special issue, led by Debra Stern of the University of Arizona in Tucson, showed a clear link between chronic asthma in early adulthood and several childhood conditions.
Follow up data on 850 infants covering a 20 year period showed, for example, that children who wheezed at age six were seven times more likely to become asthmatic.
The risk became 14 times greater for those who wheezed as adolescents.
"These findings identify a population at risk of chronic obstructive airway disease in early adulthood," noted Susanne Lau, a researcher at Charite University Medicine in Berlin.
"Whether therapeutic approaches at early preschool age can affect progression of the disease has yet to be established."
