Claim: Decrease in air pollution associated with decrease in respiratory symptoms among children False. Since air quality is not associated with childhood asthma in the first place.

One of the most important things you can do to manage your asthma is to work with your healthcare provider to identify and minimize your exposure to your asthma triggers.

Triggers are allergens, irritants, or conditions that cause your asthma symptoms to worsen. It’s important to know what triggers your asthma symptoms. Triggers vary from person to person, so you should learn which specific ones affect you. While it may be impossible to avoid every single asthma trigger, there may be things you can do to help. Being able to identify and avoid your triggers is important.

Below you’ll find tips on dealing with various types of asthma triggers. If you are able to reduce your exposure to some of these triggers but you still experience asthma symptoms, talk with your healthcare provider.

Select the triggers below to find out more.
Many people with asthma are allergic to the dried droppings and remains of cockroaches.
  • Keep food and garbage in closed containers (never leave food out)
  • Use bait or traps to eliminate cockroaches
  • If a spray is used to kill roaches, stay out of the room until the odor goes away

Decrease in air pollution associated with decrease in respiratory symptoms among children

Decreases in ambient air pollution levels over the past 20 years in Southern California were associated with significant reductions in bronchitic symptoms in children with and without asthma, according to a study appearing in the April 12 issue of JAMA.

Childhood bronchitic symptoms are significant public and clinical health problems that produce a substantial burden of disease. Ambient air pollutants are important determinants of bronchitis occurrence. Since 1992, significant improvements in air quality have been observed across Southern California due to a broad range of air pollution reduction policies and strategies. Kiros Berhane, Ph.D., of the University of Southern California, Los Angeles, and colleagues examined whether improvements in ambient air quality in Southern California were associated with reductions in bronchitic symptoms in children. The study involved children (age range, 5-18 years) from 3 groups, and was conducted during the 1993-2001, 1996-2004, and 2003-2012 years in 8 Southern California communities.

A model was used to estimate the association of changes in pollution levels with bronchitic symptoms. The primary measured outcome among children was annual age-specific prevalence of bronchitic symptoms during the previous 12 months based on the parent’s or child’s report of a daily cough for 3 months in a row, congestion or phlegm other than when accompanied by a cold, or bronchitis.
The 3 cohorts included a total of 4,602 children (average age at baseline, 8 years; 49 percent girls; 45 percent Hispanic white) who had data from 2 or more annual questionnaires. Among these children, 19 percent had asthma at age 10 years. The authors found that decreases in ambient concentrations of nitrogen dioxide, ozone, and particulate matter with an aerodynamic diameter less than 10 µm (PM10) and less than 2.5 µm (PM2.5) were associated with significant decreases in bronchitic symptoms in children with and without asthma. The reductions were proportionally larger in children with asthma and remained similar when examined at 10, 13, and 15 years of age during the follow-up period. Among patients with asthma, the reductions in bronchitic symptoms tended to be larger in boys and among children from households with dogs.

“While the study design does not establish causality, the findings support potential benefit of air pollution reduction on asthma control,” the authors write.
