Role of emergency departments in screening for obese and overweight children

IntroductionChildhood obesity is a major and increasing public health issue. The role of Emergency Departments (EDs) in screening for overweight and obese children has not been studied extensively. The main aim of this study was to estimate the prevalence of overweight children in Emergency Department (ED) populations. A secondary objective was to compare the characteristics of overweight and obese children with healthy weight children.MethodsThis prospective exploratory study was conducted in the two district urban EDs in Melbourne, Australia. A total of 87 ED patients aged 2 to 15 years were included in the study. The main outcome measures were body mass index, weight and height percentiles.ResultsThe median absolute BMI was 16.8 (IQR = 15.4 to 18.8). The total number of children found to be overweight (BMI > 85th percentile) or obese (BMI > 95th percentile) was 21.8% (n = 19). Of these, 5.7% (n = 5) of children in this study were classified as obese. Comparison of overweight/obese children and healthy weight children showed no differences in triage but a higher incidence of respiratory illness (15.8% compared to 2.9%).ConclusionsThis pilot study showed that 1 in 5 children who presented to EDs were either overweight or obese suggesting a possible role for EDs in the detection and referral of overweight and obese children to intervention programs. Our findings suggest that a sufficiently powered randomised controlled trial is warranted to examine the effectiveness and efficacy of EDs screening for obese and overweight children.
