Prevention
While there is no certain way to prevent
asthma, you can take steps to reduce your child's
airway
inflammation
and the likelihood of
asthma attacks.
No one is sure if
breast-feeding affects a child's risk of getting asthma. Some studies show that
breast-feeding protects a child from getting asthma.10, 11 Other studies show that
breast-feeding, especially when mothers with asthma breast-feed, may actually
increase a child's risk of getting asthma.12 Two large
studies found that breast-feeding had no effect on the development of
asthma.13, 14 Mothers are still
encouraged to breast-feed their children for all the other proven health
benefits that come from breast-feeding.
Preventing asthma attacks
The main focus of
prevention is on reducing the number, length, and severity of asthma attacks.
The best way to prevent asthma attacks in your child is to follow your doctor's
recommendations and make sure your child takes asthma control medications as
directed. By doing this, it is possible, in most cases, to prevent asthma
attacks. Also, by avoiding
triggers, your child may be able to prevent or reduce
the severity of symptoms. For more information on identifying your child's
triggers, see:
Asthma: Identifying your
triggers.
Below is a list of specific triggers. If you know that
any of these triggers cause your child's symptoms to become worse, you should
avoid or limit your child's exposure to them.
Upper respiratory infections
Upper respiratory
infections, including the common cold, cause 85% of asthma attacks in
young children.22 Basic preventive measures include the
following:
- Avoid contact with other people who are ill.
If there is an ill child in the home, separate him or her from other children,
if possible. Put the child in a room alone to sleep.
- If you have a
respiratory infection, such as a cold or the flu, or if you are caring for
someone with a respiratory infection, wash your hands before caring for your
child. Hand-washing eliminates the germs on your hands and the spread of germs
to your child when you touch your child or touch an object he or she might
touch.
- Do not smoke. Secondhand smoke irritates the mucous
membranes in your child's nose, sinuses, and lungs and increases his or her
risk for respiratory infections.
- Children with asthma and their family members should have a flu
shot (influenza
vaccine
(What is a PDF document?)) every year.
Irritants in the air
Common irritants in the air,
such as tobacco smoke and air pollution, can trigger asthma symptoms in some
children.
Controlling tobacco smoke is important because it is a
major cause of asthma symptoms in children and adults. If your child has
asthma, try to avoid being around others who are smoking, and ask people not to
smoke in your house.
- Pregnant women who smoke cigarettes during
pregnancy increase the risk for wheezing in their newborn
babies.
- Exposure of young children to secondhand tobacco smoke
increases the likelihood that the children will develop asthma and increases
the severity of symptoms if they already have the disease.
Consider keeping your child inside when air pollution
levels are high. Other irritants in the air (such as fumes from gas, oil, or
kerosene, or wood-burning stoves) can sometimes irritate the bronchial tubes.
Avoiding these may decrease asthma symptoms.
Allergens
Your child may be allergic to certain
substances (allergens). You may decrease your child's asthma
symptoms by limiting exposure to those substances.
To help reduce
your child's exposure to allergens:
- Control cockroaches, especially if you
and your child live in an inner-city area or the southern part of the United
States.
- Control dust mites. House dust mites have been linked
with the development of asthma in children.1
- Control animal dander and pet
allergens. If your pet is a known trigger for your child, you may need
to think about giving your pet away. If that is too hard, taking steps such as
keeping your pet out of your child's bedroom and dusting and vacuuming often
may help your child's asthma.
- Control indoor mold,
especially if you live in an area with high humidity.
It also may be necessary to avoid exposure to other types
of triggers that cause asthma symptoms.
- Control your child's exposure to
pollens in the air. Watch local weather reports or
read the local newspaper for pollen counts in your area.
- Limit your
child's exercise outdoors in cold weather. The air may irritate airways. Have
your child wear a scarf around his or her face and breathe through the
nose.
- Have your child avoid foods that may cause asthma symptoms.
Some children have symptoms after eating processed potatoes, shrimp, or dried
fruit. These foods and liquids contain sulfites, which may cause asthma
symptoms.
- Consider using acetaminophen (such as Tylenol) for pain relief
instead of similar medications such as ibuprofen if they increase asthma
symptoms. (Do not give aspirin to anyone younger than 20
because of the risk of
Reye's syndrome.)
Some research indicates that children who have older
siblings or who attend day care may receive some protection from developing
asthma.23 One theory as to the increasing prevalence of
asthma suggests that low exposure to some bacteria and infections may prevent
children's
immune systems from forming the cells necessary to
protect against asthma.
