Christian NJ, King WC, Yanovski SZ, Courcoulas AP, Belle SH. Validity of Self-reported Weights Following Bariatric Surgery. JAMA. 2013;310(22):2454–2456. doi:10.1001/jama.2013.281043
Obtaining standardized weights in long-term studies can be difficult. Self-reported weights are more easily obtained but are less accurate than those from a calibrated scale and may be inaccurately reported. Previous studies have reported that women tend to underreport their weight more than men with the degree of misreporting related to body mass index (BMI), whereby overweight individuals tend to underreport and underweight individuals tend to overreport.1-4 However, in a study of female gastric bypass candidates, self-reported presurgical weights averaged 0.3 kg more than measured weights and misreporting was not significantly related to BMI.5
This study investigated whether self-reported weights following bariatric surgery differed from weights obtained by study personnel using a standard scale.
