Childhood and adolescent obesity is increasing in prevalence and is known to have long-term medical and musculoskeletal consequences. The baseline Pediatric Outcomes Data Collection Instrument (PODCI) was administered to 50 obese patients (>95th percentile BMI for age) or their parent (for those <11 years) presenting to a pediatric orthopaedic clinic to assess overall function. There were no differences between sexes (31 boys, 19 girls) or age group (>11 years, n = 36; <11 years, n = 14) in any demographic or PODCI category. Compared with normative data, there was significant impairment in sports and pain identified in both genders, African-Americans, and those older than 11 years. These findings were consistent when comparing genders, ethnicities, and ages. There was no difference in happiness between any gender, age, or ethnic group. All groups reported essentially neutral satisfaction. There appears to be a lack of self-recognition of or reluctance to admit functional impairment secondary to obesity. Being obese, African-American ethnicity, and age older than 11 years appear to be risk factors for limited, yet significant, functional impairment.
