Childhood asthma prevalence was found to be higher than 15 percent in a majority of Latin American countries. [31] Similarly, a study published relating to asthma prevalence in Havana, Cuba estimated that approximately 9 percent of children under the age of 15 are undiagnosed for asthma, possible due to lack of resources in the region.

Childhood asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to recurrent episodes of wheezing, shortness of breath, chest tightness and coughing. Around 4.9 million children in the US suffer from asthma [1]. It is difficult to diagnose asthma in children younger than 6 years of age.
The concept that "non-atopic" is synonymous with "non-allergic" is called into question by epidemiological data that the prevalence of asthma is closely related to the serum IgE level standardized for age and sex (P<0.0001), indicating that asthma is almost always associated with some sort of IgE-related reaction and therefore has an allergic ...
NHIS is designed by the CDC's National Center for Health Statistics (NCHS) – the government agency tasked to monitor the population's health status and behavior – and administered by the U.S. Census Bureau. [1] NHIS has been administered since 1957, although the core content and questionnaires undergo major revisions every 10–15 years. [2]
Children who suffer from frequent respiratory infections prior to the age of six are at higher risk of developing asthma, particularly if they have a parent with the condition. However, persons of any age can have asthma triggered by colds and other respiratory infections even though their normal stimuli might be from another category (e.g ...
GINA conducts continuous review of scientific publications on asthma and is a leader in disseminating information about the care of patients with asthma. [2] GINA publishes resources such as evidence-based guidelines for asthma management, and runs special events such as World Asthma Day. GINA's guidelines, revised each year, are used by ...
Atopy, reduced lung function, and respiratory infections in infants with wheeze are risk factors for asthma persistence into adulthood, and a lower lung function and greater magnitude of atopy at this age is associated with more severe disease. [5] Severe atopic asthma is also additionally amenable to anti-immunoglubulin E (IgE) therapy. [4]
