A new study challenges the widely held belief that inner-city children have a higher risk of asthma simply because of where they live. Race, ethnicity and income have much stronger effects on asthma risk than where children live, the Johns Hopkins Children's Center researchers reported. The investigators looked at more than 23,000 children, aged 6 to 17, across the United States and found that asthma rates were 13 percent among inner-city children and 11 percent among those in suburban or rural areas. But that small difference vanished once other variables were factored in, according to the study published online in the January 20 issue of the Journal of Allergy and Clinical Immunology.

January 9, 2015

Babies who gain weight rapidly in the first three months of life are more likely to develop asthma and for it to persist into adolescence. This is according to the latest research from the University of Bristol's Children of the 90s study, which analyzed information on height, weight and asthma symptoms in almost 10,000 people enrolled in the study at various points in time from birth to age 17.

Asthma May Boost Sleep Apnea Risk


January 1, 2015

According to a study published in the Journal of the American Medical Association (JAMA), asthma may lead to obstructive sleep apnea, a narrowing or closing of the upper airways during sleep. The new study examined the prospective relationship between pre-existing asthma and new obstructive sleep apnea (OSA) in the Wisconsin Sleep Cohort Study. The primary finding from the study: participants with pre-existing asthma were 40 percent more likely to develop OSA than those without pre-existing asthma.

Most People With Inhalers, EpiPens Don’t Use Them Right

ABC News

December 18, 2014

EpiPens and asthma inhalers have the potential to save lives with a simple jab or puff, but a small study published suggests that many people may be using these vital devices incorrectly. Researchers at the American College of Allergy, Asthma and Immunology observed patients as they demonstrated how they would use inhalers and learned that most of the patients were unable to use the devices properly, keeping them from getting the medication when needed most.

Raised Asthma Risk Seen for Toddlers Who Share Bed with Parents


December 11, 2014

Toddlers who share a bed with their parents may have an increased risk of developing asthma later in childhood, a new study finds. Children who shared a bed with their parents during infancy (two months old) did not have an increased risk of developing asthma by the time they were six years old. However, children who shared a bed with their parents when they were toddlers (age 24 months) were more likely to experience wheezing between ages three and six, and an asthma diagnosis by age six.

Don’t Let Asthma Keep You From Exercising

The Washington Post

December 8, 2014

Mike Plunkett

Almost 19 million American adults have adult-onset asthma, a chronic lung disease that inflames and narrows the airways. About 90 percent of them — plus about 10 percent of the general population — periodically suffer a related condition called exercise-induced bronchoconstriction, in which someone running or doing other strenuous exercise suddenly struggles to be able to breathe, with little or no warning. It’s understandable that adults with these conditions — and there are more all the time, doctors say, due partly to poor air quality and other environmental factors —may find some types of fitness to be an arduous endeavor that ultimately won’t be worth the effort. But experts say that knowledge of both conditions is improving and, in consultation with physicians, it is possible for sufferers to exercise and maintain an active lifestyle.

Link Between Antibiotics and Childhood Asthma Called Into Question

Medical News Today

December 2, 2014

Researchers found that results from previous studies linking increased use of antibiotics and a concurring increase in childhood asthma should be called into question. As it may be difficult to diagnose asthma in small children, new asthma symptoms can often be misinterpreted as a respiratory infection. As such, many children may have received antibiotics for the "infection," which is actually asthma, and the antibiotics are then suspected to have caused the asthma when later discovered.

Job Worries Can Raise Asthma Risk, Study Says


September 23, 2014

Fear of losing your job can increase the risk for developing asthma, according to a new European study. The study involved more than 7,000 employed adults in Germany. Between 2009 and 2011, during the economic downturn in Europe, the workers answered questions about the respiratory disorder and also on whether they thought they would lose their job within two years. More than 100 new cases of asthma were diagnosed among the survey group, half of whom were women, during the study period.

Researchers Shed Light on Asthma's Mysteries

Wall Street Journal

September 22, 2014

Researchers are making interesting new discoveries about a particularly confusing type of asthma. Doctors increasingly are recognizing that as many as half of asthma sufferers have a form of the lung disease known as non-allergic asthma. Some medications that help control symptoms of the more familiar allergic asthma aren't as effective in non-allergic patients.

Prenatal Exposure to Chemicals in Plastics Linked to Asthma Risk in Kids


September 17, 2014

Exposure in the womb to household chemicals known as phthalates might increase a child's future risk of developing asthma, Columbia University researchers reported in a new study. Children had nearly an 80 percent increased risk of developing asthma between age 5 and 11 if their mothers were exposed during pregnancy to high levels of two phthalates (pronounced thal-ates), the researchers found. The two phthalates were butylbenzyl phthalate and di-n-butyl phthalate, according to the study.

Long-term effects of childhood asthma influenced by socioeconomic status

Medical Xpress

September 15, 2014

According to the Centers for Disease Control and Prevention (CDC), approximately 6 percent of children younger than five have been diagnosed with asthma, the fastest-growing and most common chronic illness affecting children in the United States. Studies have shown that asthma is associated with attention and behavioral issues in children, yet little existing research examines how socioeconomic status may influence the ultimate effects of these difficulties.

Enterovirus D68: What Parents Need to Know


September 9, 2014

A fast-spreading virus related to hand-foot-and-mouth disease is hospitalizing kids across the country. The virus, enterovirus D68, or EV-D68, was first discovered in 1962 in California. But until now, it has only been tied to smaller clusters of disease around the U.S. This is the first time it’s caused such widespread misery, and it seems to be particularly hard on the lungs.

Enterovirus 68 outbreak: which kids most at risk?

The Boston Globe

September 8, 2014

A sudden surge in pediatric emergency room visits in at least a dozen states has been linked to an uncommon respiratory virus, called Enterovirus 68, and public health officials have been scrambling to determine where it’s spreading and why it’s hitting some children harder than others. “It’s not a new strain and is the same EV-68 strain identified in the US last year,” said Dr. Anne Schuchat, director of the Center for Disease Control and Prevention’s National Center for Immunization and Respiratory Diseases.

Sleeping On Animal Fur Can Lower Asthma Risk


September 8, 2014

Animal fur may be protective against asthma and allergies, a new study finds. The research, presented at the European Respiratory Society International Congress, examined data from 2,441 German children and found an association between sleeping on animal fur, like sheepskin rugs or throws, during their first three months and a decreased risk of asthma later in childhood, by age 10.

Study Reveals Childhood Obesity Leads to Asthma

Science World Report

September 4, 2014

A new study provides evidence that childhood obesity contributes to asthma. For several decades, health experts have believed that childhood obesity and asthma are linked; however, they could not determine which of the two conditions comes first and whether one condition leads to the other. Childhood obesity is listed as a serious U.S. public health problem and the rate has doubled in children and quadrupled in adolescents over the last 30 years, according to the U.S. Centers for Disease and Control.

Asthma attack rates similar for black and white kids


August 21, 2014

A new analysis of U.S. childhood asthma statistics finds racial differences persist in the proportions of African American and white children who develop asthma, but success in managing the disease is becoming more equal. Disparities between white and black kids with asthma in rates of emergency department visits or hospitalizations have shrunk and rates of asthma attacks – another sign of poorly managed asthma – are the same, researchers found.
