Abstract OBJECTIVE: To determine whether inhaled steroid therapy causes delayed linear growth in children with asthma. DATA SOURCES: Medline (1966-1998), Embase (1980-1998), and Cinahl (1982-1998) databases and bibliographies of included studies were searched for randomized, controlled trials of inhaled steroid therapy in children with asthma that evaluated linear growth. STUDY SELECTION: Studies were included if they met the following criteria: subjects 0 to 18 years of age with the clinical diagnosis of asthma; subjects randomized to inhaled beclomethasone, budesonide, flunisolide, fluticasone, or triamcinolone versus a nonsteroidal inhaled control for a minimum of 3 months; single- or double-blind; and outcome convertible to linear growth velocity. English- and non-English-language trials were included. DATA EXTRACTION: Data were extracted using a priori guidelines. Methodologic quality was assessed independently by both authors. Outcome was extracted as linear growth velocity. RESULTS: Included trials were subgrouped by inhaled steroid. The beclomethasone subgroup, with 4 studies and 450 subjects, showed a decrease in linear growth velocity of 1.51 cm/year (95\% confidence interval: 1.15,1.87). The fluticasone subgroup, with 1 study and 183 subjects, showed a decrease in linear growth velocity of.43 cm/year (95\% confidence interval:.01,.85). Sensitivity analysis in the beclomethasone subgroup, which evaluated study quality, mode of medication delivery, control medication, and statistical model, showed similar results. CONCLUSIONS: This meta-analysis suggests that moderate doses of beclomethasone and fluticasone in children with mild to moderate asthma cause a decrease in linear growth velocity of 1.51 cm/year and.43 cm/year, respectively. The effects of inhaled steroids when given for >54 weeks, or on final adult height, remain unknown.
