Researchers, co-led by Peige Song and Davies Adeloye, aimed to provide global and regional estimates of <a href="https://www.cdc.gov/asthma/default.htm">asthma</a> prevalence and cases in 2019. In their report, published in the Journal of Global Health, they ultimately concluded that, &ldquo;although varying approaches to case identification in different settings make epidemiological estimates of asthma very difficult, this analysis reaffirms asthma as a common global respiratory condition before the COVID-19 pandemic in 2019, with higher prevalence than previously reported in many world settings.&rdquo;The authors&rsquo; analysis included 220 population-based studies carried out prior to December 31, 2019 across 88 countries. Asthma was divided into four epidemiological case definitions: current wheezing, ever wheezing, current asthma, and ever asthma. Multilevel multivariable mixed-effects meta-regression models, random-effects meta-analysis, and a &ldquo;risk factor-based model&rdquo; were used to assess associations between asthma and study-level variables, risk factors for current wheezing and asthma, and regional asthma prevalence and case numbers in 2019, respectively. A follow-up analysis was also performed to estimate regional and national distributions of prevalence and cases for the current wheezing and ever asthma statuses.<h3>2019 Global and Regional Prevalence of Asthma Findings</h3>The authors estimated a global prevalence of current wheezing, ever wheezing, current asthma, and ever asthma of 11.5% (95% CI, 9.1-14.3), 17.9% (95% CI, 14.2-22.3), 5.4% (95% CI, 3.2-9.0), and 9.8% (95% CI, 7.8-12.2), respectively, in people aged 5-69 years in 2019. This equated to 754.6 million (95% CI, 599.7-943.4), 1,181.3 million (95% CI, 938.0-1,471.0), 357.4 million (95% CI, 213.0-590.8), 645.2 million (95% CI, 513.1-806.2) cases, respectively.Reportedly, the African Region had the highest prevalence of current wheezing at 13.2% (95% CI, 10.5-16.5), while the Americas Region had the lowest at 10.0% (95% CI, 8.0-12.5). Comparatively, the estimated prevalence of ever asthma was also highest in the African Region at 11.3% (95% CI, 9.0-14.1), but was lowest in the South-East Asia Region at 8.8% (95% CI, 7.0-11.0).Ultimately, the authors concluded that, &ldquo;asthma, based on whichever definition is used, was more common than previously estimated&rdquo; prior to the <a href="https://www.docwirenews.com/covid-19/new-omicron-subvariant-is-spreading-in-india-u-s/">COVID-19 pandemic</a>, and they proposed that their findings &ldquo;should be particularly useful for planning a national and sub-national response to asthma and will complement other international research efforts.&rdquo;Browse more <a href="https://www.docwirenews.com/">recent studies, interviews with experts, and more</a>
