Asthma deaths have risen steadily in the United States, with the highest rate among black male children, researchers say. Asthma afflicts an estimated 9.9 million people in the United States and "affects children, blacks and the poor disproportionately," researchers said in this week's Journal of the American Medical Assn. The researchers noted that, from 1968 almost through the 1970s, the nation's asthma mortality rates declined.

Cockroach allergies may be the most important cause of asthma in America's inner cities, where rates of the breathing disorder have been skyrocketing, a major new study has found. Moreover, allergies to the creeping pest provoke an unusually severe form of asthma that is probably the source of the disproportionately high incidence of asthma-related illnesses and hospitalizations in urban neighborhoods, the study said.

Some patients using a popular asthma medication called salmeterol face a small, increased risk of severe, and occasionally fatal, asthma attacks, the Food and Drug Administration warned Thursday. The side effects are rare, and the FDA said the drug's benefits still appear to outweigh the potential risks when patients follow medication instructions. It is dangerous to stop taking the drug, so patients should consult a doctor, the FDA cautioned.

A Quebec coroner said a severe asthma attack killed a teenager who was previously believed to have died of a peanut allergy after kissing her boyfriend. Michel Miron said Christina Desforges, 15, died of cerebral anoxia, or lack of oxygen to the brain, triggered by the attack. The girl stopped breathing Nov. 20 after kissing her boyfriend, who had eaten peanut butter several hours earlier. Miron said she had spent hours at a party with smokers when her breathing problems began.

Researchers trying to account for the surge in childhood asthma have studied genetics, infections and allergies. Now they've identified another possible culprit: poor parenting skills. In following 150 children for eight years, beginning at birth, psychologists at National Jewish Medical and Research Center in Denver found that kids whose parents had trouble coping--especially during the child's first year--were more than twice as likely to become asthmatic by age 6 to 8.

Researchers who conducted separate studies in New York, Connecticut, New Jersey and Georgia think they've found one explanation for the national upsurge in asthma, and that reason is smog. For papers slated for presentation soon at medical conferences and in journals, they charted hospital visits, hospital admissions and asthma symptoms.

Inhaled steroids, widely used to treat asthma, cause bone loss in young women, researchers report. Anti-inflammatory steroids taken in pill form are known to accelerate bone loss, but it was not clear whether steroids inhaled directly into the lungs also thin bones. Researchers at Boston's Brigham and Women's Hospital found a direct relation between the amount of inhaled steroids used and a decrease in bone density in the 109 women studied. Bone loss can lead to osteoporosis.

A link between asthma and being overweight could mean that adults who shed the fat might also ease their asthma, researchers said. But their study was not able to determine if the added weight caused the asthma, or if asthma resulted in the weight gain. About 10.3 million Americans, nearly 6% of the population, suffer from asthma.

The number of Americans who suffer from asthma has risen 75% since 1980 to more than 15 million, in part due to pollution and other environmental factors, federal health officials said. The Centers for Disease Control and Prevention in Atlanta said the number of doctors' office visits for asthma had more than doubled since 1975. There were more than 1.8 million emergency room visits for asthma in 1995.

A bacteria only recently revealed as a major cause of ulcers and stomach cancer may help protect children from developing asthma, U.S. researchers reported Tuesday. Children ages 3 to 13 who were infected with Helicobacter pylori were 59% less likely to have asthma than those who were not infected, according to a study published in the journal Clinical Infectious Diseases. Researchers used data on more than 7,000 U.S. children from the National Health and Nutrition Examination Survey conducted from 1999 to 2000 by the National Center for Health Statistics.
