Correlation Between Age and Weight Loss after Bariatric Surgery
Open accessAbstract
Background Conflicting evidence exists regarding age as a predictive factor in excess weight loss after bariatric surgery. The objective of this cross-sectional study is to evaluate differences in excess BMI loss (%EBMIL) 1 year after surgery in patients older and younger than 45 years.Methods Adult obese patients fulfilling selection criteria underwent either Roux-en-Y gastric bypass or sleeve gastrectomy and were grouped according to age < and ≥45 years with follow-up at least 1 year. Both groups were compared in terms of excess BMI loss (%EBMIL) and other clinical outcomes. Possible relationship between %EBMIL, age, surgical technique, and presence of comorbidities such as diabetes mellitus, hypertension (HT), and dyslipidemia (DL) was searched.Results Three hundred thirty-seven patients (72.5 % female), 196 (50.1 %) younger than 45 years and 141 (49.9 %) with age ≥45 years. There was significant difference between age group and %EBMIL 12 months after surgery (p < 0.001), showing better results in younger patients. No differences were found in terms of gender, preoperative body mass index (BMI), surgical technique, nor presence of DL. Using multiple regression, we found significant interaction effect between age group (p < 0.001), presence of HT (p = 0.001), and %EBMIL at follow-up.Conclusions Patients younger than 45 years lose greater amount of excess BMI than older patients after bariatric surgery. This tendency might be useful as a preoperative weight loss predictor in bariatric patients.

“Age as a predictor of weight loss has received only a modest amount of attention, but findings indicate that younger patients lose more weight [40], which coincides with our result.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
