A comparison of asthma hospitalization rates (age-adjusted) in Wayne County and the state of Michigan from 2000-2002 with Healthy People 2010 targets by age group (data from Michigan Inpatient Database, Bureau of Epidemiology, Michigan Department of Community Health [2005]). Note that asthma hospitalization was defined as a primary discharge diagnosis.

The U.S. Department of Health and Human Services (2000) has developed Healthy People 2010 — a set of disease prevention and health promotion objectives for the nation to achieve by the year 2010. Objective 24-2 of Healthy People 2010 gives the following target rates of asthma hospitalization by age group:

• Age 0-4 years: 25 per 10,000 people
• Age 5-64 years: 7.7 per 10,000 people
• Age ≥ 65 years: 11 per 10,000 people

Based on asthma hospitalization rates for 2000-2002, both Wayne County and the state of Michigan are significantly higher than the Healthy People 2010 targets established for all age groups (Michigan Department of Community Health 2005).
