Wheeze in preschool children: who is followed-up, who is treated and who is hospitalized?
This study determined the proportions of children < or = 5 yrs of age with reported wheeze who were undergoing medical follow-up, receiving anti-asthma medication, or admitted to hospital; and investigated factors important in determining which children would receive these treatments. The symptomatic children represented a wheeze prevalence of 16% of the study sample of 1,422 children. The cumulative incidence of treatment and hospitalization and point prevalence of current medical follow-up were determined using a parent-answered postal questionnaire study of a population-based random sample of 222 children. Odds ratios (OR) were calculated for wheeze severity, environmental, social, familial and demographic factors found to affect the likelihood of these treatment end-points. Among 222 children with wheeze, 99 (35%) were under current medical review, 165 (75%) had received medication, and 48 (22%) reported being hospitalized. Current follow-up was more likely in girls (OR 2.22; 95% confidence interval (95% CI) 1.12-4.38), with more than three attacks of wheeze in the last year (OR 17.44; 95% CI 5.22-58.3), or with a household pet (cat or dog) where inhalants were wheeze precipitants (OR 13.65; 95% CI 3.16-58.94). Treatment became more likely in older children (OR 3.91; 95% CI 1.10-12.71), with inhalants as wheeze precipitants (OR 4.66; 95% CI 1.08-20.14) or with a household pet (OR 2.28; 95% CI 1.04-5.03). Hospitalization was less likely with frequent wheeze (OR 0.30; 95% CI 0.12-0.77), but more likely if shortness of breath occurred with wheeze. Medical follow-up and treatment are related to wheeze severity and exposure to inhaled precipitants, whereas hospital admission occurred in children with attacks causing shortness of breath, and with decreasing frequency of attacks per year.
