Asthma-related Missed School Days among Children aged 5–17 Years

The percent of children with asthma who reported one or more missed school days in 2013 was significantly lower than in 2003.

Poorly controlled asthma may impair a child’s ability to attend school, affect his or her academic performance, and cause parents to miss work to care for an ill child.*

The number of reported missed school days among children with asthma^† was 12.4 million in 2003, 10.4 million in 2008, and 13.8 million in 2013.

The percent of children with asthma^† who reported one or more asthma-related missed school days in 2013 (49.0%) was significantly lower than the percent in 2003 ( 61.4% ). However, this percentage was similar to the percentage for 2008 (59.6%). The reported missed school days in each year did not differ by age, sex, race or ethnicity, and poverty level.

CDC’s National Asthma Control Program was created in 1999 to help the millions of people with asthma in the United States control their disease. The Program conducts national asthma surveillance and provides funds to states to help improve asthma surveillance and focus efforts and resources where they are needed.
