Asthma control among teenagers attending the respiratory outpatient clinic of an academic hospital in Pretoria, South Africa

Abstract

Objectives: Bronchial asthma is characteristically a diverse illness that results from chronically inflamed bronchi. Adolescents are a particularly vulnerable group to asthma, and both its prevalence and death rate have increased in this patient population. Asthma care creates a particular set of difficulties for adolescents who are at a stage where there is a search for greater autonomy and changing social and emotional dynamics. The aim of this study was to describe the clinical characteristics of teenage asthmatics in an academic hospital. Materials and Methods: This was a cross-sectional study of patients between the ages of 13 and 18 who had consented to participate. The study consisted of face-to-face interviews and a review of their clinical and laboratory records. Data were analyzed using descriptive statistics and comparisons between groups made using Fisher’s test of exactness. Results: Eighty-seven teenagers were studied. The mean age was 15.5 ± 1.5 years. The majority (59%) were male. Ten study subjects (11.5%) were current smokers. A positive family history of asthma was found in 31% (n = 27) of the patients. All patients were on inhaled corticosteroid therapy. The majority of the study subjects (60.9%) had satisfactory asthma control as evidenced by a mean asthma control test score (ACT) of 19.2 ± 2.29. Fifteen patients (26.7%) had had an acute flare-up of the disease requiring hospitalization in the preceding 12 months, and 5.8% had had a previous intensive care unit admission. Conclusion: The majority of the teenagers studied had overall satisfactory asthma control, as determined by their ACT scores. The use of inhaled corticosteroids was standard, but the inhaler technique was largely unsatisfactory. The prevalence of tobacco use is a cause for concern.
