Purpose
This study evaluates accuracy of self-reported weight in adolescent bariatric surgery patients.
Materials and Methods
During follow-up visits, participants self-reported weight and had weight measured. The differences between self-reported and measured weights were analyzed from 60 participants.
Results
Participants were 70% (n = 42) female, 72% (n = 43) white, mean age of 20.8 years and a median body mass index of 36.6 kg/m2. At an average of 3.5 years following surgery, females underestimated weight (0.5 kg, range: −18.7 to 5.6 kg), while males overestimated (1.1 kg, range: −7.8 to 15.2 kg). Most (80%, n = 48) reported within 5 kg of measured weight. The majority of adolescents who previously underwent bariatric surgery reported reasonably accurate weights, but direction of misreporting varied by gender.
Conclusion
Self-reported weights could be utilized when measured values are unavailable without markedly biasing the interpretation of outcomes.
