Work-Related Asthma a Significant Problem: CDC

THURSDAY, May 24 (HealthDay News) — About nine percent of all
asthma cases in the United States are caused or made worse by work-related
exposures, a new federal study says.

That means work-related asthma affects about 1.4 million adults
annually, the researchers said.

State-by-state rates of workplace-related asthma ranged from 4.8
percent (Arizona) to just over 14 percent (Florida), according to the
study by researchers at the U.S. Centers for Disease Control and
Prevention.

The analysis of 2006-09 data from 38 states and the District of
Columbia also suggests that older workers and those in certain ethnic or
minority groups are most at risk. For example, rates of employment-related
asthma were 12.7 percent for people ages 45-64 vs. about 7 percent for
people ages 18-44. Among racial groups rates of work-related asthma were
12.5 percent for blacks, 10.5 percent for Hispanics and 8.2 percent for
whites, the report found.

The estimated proportion of adults with current asthma who had
work-related asthma was similar for men and women, at about nine
percent.

Asthma linked to on-the-job exposures is a preventable but
under-recognized illness and the new findings highlight the need to expand
workplace surveillance to better understand the risk factors and to better
focus prevention efforts, the researchers said.

Better surveillance of the problem “would enhance our understanding of
work-related asthma epidemiology and enable states, other government
agencies, health professionals, employers, workers and worker
representatives to better target intervention efforts to reduce the burden
of work-related asthma,” the researchers wrote in a summary.

The study appears in the May 25 issue of the CDC’s Morbidity and
Mortality Weekly Report
