Trends in adult asthma in the United States, 2005-2018, National Health and Nutrition Survey
American adults often suffer from asthma. Although there has been little research on the long-term trajectory of asthma in American adults, the prevalence of asthma has changed over time. For one study, researchers sought to examine asthma risk factors and detail the prevalence and trend of asthma among American adults from 2005 to 2018. From 2005 to 2018, the National Survey of health and nutrition was used to collect data. Weighted and unweighted percentages of healthy participants, asthma patients, and asthma trends were calculated. Risk variables for asthma were examined using weighted univariate logistic regression. The study included 39,601 adult participants in total. Between 2005 and 2018, 8.41% of American adults in America had asthma, compared to 8.30%, 8.70% and 7.92% for young, middle-aged and elderly people. The estimated prevalence of asthma in middle-aged and elderly adults was stable over time (P for trend=0.33, difference=0.015 and P for trend = 0.80, difference = 0.024, respectively), while it increased over time in young adults and adults in general (P for trend=0.03, difference=0.023 and P for trend=0.007, difference=0.060, respectively). Adults in America had an increase in asthma. An increased risk of asthma was linked to female gender, non-Hispanic black people, low annual household income, active smokers, obese patients, patients with hypertension, diabetes, and people with a family history of asthma. asthma.
