Figure 1.
Prevalence of current asthma and asthma attacks among all ages by year. The Pvalue of the trend line slope is significant at P < .05. The trend line is based on estimates from the statistical model and observed prevalence estimates (estimates as is from the survey data) (dots). The trend slope is numbered (slope 1, slope 2) when there is more than one significant trend line, as in the current asthma trend lines. Data source: National Center for Health Statistics, National Health Interview Survey, 2010–2021 (14).

Figure 2.
Asthma-related health care use and death rate among all ages by year. The P value of trend line slope is significant at .05. The trend line is based on estimates from the statistical model and observed prevalence estimates (estimates as is from the survey data) (dots). The trend slopes are numbered (slope 1, slope 2) when there is more than 1 significant trend line, as in the current asthma trend lines. The health care use rate is shown as the number of hospitalizations and emergency department visits per the US Census resident population for the given year. Data sources: asthma emergency department visits and hospitalizations: Healthcare Cost and Utilization Project, National (Nationwide) Inpatient Sample (16) and National (Nationwide) Emergency Department Sample (15), Agency for Healthcare Research and Quality. Asthma deaths: CDC Wonder (Wide-Ranging Online Data for Epidemiologic Research) (17).
