Certain genetic factors and wheezing early in life are associated with a greatly increased risk of asthma in children, a new study says.
Researchers examined data from nearly 500 children and found that about 90 percent of those who had two copies of a common genetic variation and who also experienced wheezing when they had a cold early in life developed asthma by age 6.
These children, all from families with a history of asthma or allergies, were nearly four times more likely to develop asthma than those who did not have the genetic variation and did not wheeze, according the study in the March 28 issue of the New England Journal of Medicine.

Read MoreAsthma patients typically use two inhaled drugs -- one a fast-acting "rescue inhaler" to stem attacks and another long-lasting one to prevent them.
However, combining both in one inhaler may be best for some patients, two new studies suggest.
Patients with moderate to severe asthma who used a combination inhaler had fewer attacks than those on two separate inhalers, researchers report. Both studies tested the so-called SMART (single maintenance and reliever therapy) protocol.

A new treatment for asthma can cut emergency hospital visits by half by suppressing inflammation in the lungs, a study has found.
The drug for people with severe asthma may allow patients to reduce their dependence on traditional steroid inhalers, experts said.
The research conducted by a team at Leicester University, the largest of its kind in severe asthma, found the treatment could reduce severe asthma attacks, A&E visits and admissions to hospital by 50 per cent compared with a dummy drug.
It could be a new treatment for around one third of asthma patients with a particular form of the disease. Read MoreAllergy symptoms have you feeling less like Wonder Woman and more like Ugly Betty? These beauty tips from top Hollywood makeup artists will help.
