Abstract
Objectives: To measure the prevalence of obesity and to assess associated clinical factors in children and adolescents with acquired brain injury (ABI).
Study design: This cross-sectional study included 88 subjects aged between 2.4–17.7 years attending the Brain Injury Clinic at a tertiary paediatric hospital. Body mass index (BMI) and BMI z-scores were calculated. Obesity and overweight were defined using the International Obesity Taskforce cut-points. Associations were examined between BMI z-scores and the following: ABI severity, mobility level, duration from injury and presence of radiological injury.
Results: The prevalence of obesity in this population (obese = 15%) was higher than those in Australian children and adolescents (1995 National Nutrition Survey) while the prevalence of overweight (19.3%) was comparable. There was a linear trend for the participants to have a higher BMI z-score with increasing level of mobility (F = 6.91, df 1.70, p = 0.011).
Conclusion: There is no data about obesity in children and adolescents with ABI. The study with limited statistical power suggests that obesity is prevalent in this population and increases with increasing level of mobility. Further studies are required to address the issue of obesity and related complications in this population.
