A clinical description of asthma and its prevalence

This has increased the recognition for the personal, family and community problems and costs associated with asthma. It became apparent that specially-trained, knowledgeable health care providers were needed to teach patients what they need to know to control this complex disease. The national asthma guidelines, published by the National Heart, Lung, and Blood Institute, recognize asthma education as an important part of controlling asthma.

During the past 12 months, did you have asthma? One should note, however, that survey questions have changed, and NHANES 2 included questions about allergy which may have resulted in an increased ascertainment of asthma cases.

Asthma here was defined as asthma recognized by a physician at call up examination, exemption from military service because of disabling asthma, and discharge during the year of required military service because of asthma 8.

In year-old Swedish military conscripts, the prevalence of asthma increased from 1. Using a questionnaire, Robertson et al. The authors noted that part of this increase may have been due to increased awareness of both asthma and the symptom of wheeze by health care providers and the public.

Using a self-administered questionnaire, they found significant increases in both populations in the prevalence of doctor diagnosed asthma, recent use of an asthma drug, and episode of wheeze. A histamine inhalation test was included as an objective measurement of airway responsiveness, and those children with both recent wheeze and airway hyperresponsiveness were classified as cases of asthma.

The prevalence of airway hyperresponsiveness increased significantly in Belmont Likewise, the prevalence of current asthma increased in Belmont 7.

Prevalence studies from England are not consistent in their results. In reviewing asthma prevalence studies conducted in the United Kingdom between andAnderson 4 concluded that there is "little evidence" of a trend in estimates of prevalence of wheezing described as 'current' or 'recent'.

Prevalence of diagnosed asthma did show a tendency to increase in recent years. In a longitudinal study of English children 4 to 12 years of age, Burney et al.

However, as was stated earlier, comparisons of studies can be limited by differences in research methodologies. A few studies have employed standardized methodologies in order to provide a comparative analysis of prevalence in different countries. The prevalence of asthma in children in New Zealand and Australia has been reported to be higher than that found in other countries 3.

One study compared the prevalence of asthma in year-olds in New Zealand and South Wales. Using the same questionnaire and an exercise provocation test in both countries, this study found New Zealand children to have a higher prevalence of reported history of asthma or wheeze and were more likely to have a positive exercise provocation test Their data showed that children in New Zealand had the highest prevalence of asthma ever, current asthma, and wheeze without a cold.

Swedish children had the lowest prevalence of asthma and asthma-like symptoms Throughout the world asthma morbidity and mortality appear to be increasing 4,15,16and as with prevalence, the reasons for these trends are not clear. Defining and identifying the disease again are obstacles in understanding trends.

Various factors hypothesized to be contributing to increasing mortality trends include: The effect was similarly evaluated in New Zealand year olds, and an expected increase of just 2. Additionally, trends from toafter the coding change, show a continued increase in many countries, such as Italy, Denmark, Israel, Australia, France, and the United States.

New Zealand, Sweden, and Japan experienced decreased mortality during this time period In year olds, this rate increased from 3. Trends in hospitalization among children years of age in the U. Using the National Hospital Discharge Survey, they found a 4. African American children 0 to 4 years old had about 1.

Their analyses of data regarding admissions for lower respiratory tract disease and bronchitis showed decreases that suggested diagnostic transfer may have contributed in part to increased hospitalizations. In the UK, hospitalizations due to asthma in children were increasing until the mids.

A study using data from the Hospital In-Patient Enquiry which provides hospital admission data for England and Walesdescribed trends in admission rates in England and Wales tothe East Anglian region toand Wales The rates for England and Wales combined increased through In East Anglia, rates rose until when they peaked and then appeared to decline.

Rates in Wales increased until a peak in and a subsequent decline. A change in the information system used to collect hospital admission data may have confounded these trends, but the observation that some of the downwards trends were started before the system change suggests that this change may have only partly contributed to the observed trends.

Other possible factors included changes in medical care delivery, treatment, hospital admission and readmission policies, and severity or prevalence of asthma. The researchers also noted that recent asthma mortality data supports a possible true change in asthma morbidity Of special note are the two "epidemics" of asthma mortality in New Zealand, the first in the s and another in the s.

I will just mention a few key points. In the s large increases in asthma mortality were also seen in England and Wales, Scotland, Ireland, Australia, and Norway; however, mortality rates remained relatively stable in the U.The outcome of a very recent collaboration between the Global Initiative for Asthma (GINA) and Global Initiative for Chronic Obstructive Lung Disease (GOLD) are dealing with a clinical description of ACOS.

Sex specific differences in prevalence of allergic rhinitis and asthma over the life span were recognized, showing a higher prevalence of allergic rhinitis and asthma as single entities in boys than in girls during childhood followed by an equal distribution in adolescence [2, 3].
