“…The main limitations of our study come from its retrospective nature. Firstly, it was impossible to retrospectively assess the baseline social support of each patient, which has been shown to impact postoperative weight loss [ 12 ], and thus we could not correct for it in our multivariable analysis. Additionally, we had a high follow-up attrition rate after the second year which inhibits us from identifying any potential weight loss benefit after 3 or more years out of surgery.…”

Background Patients’ social support has been shown to impact outcomes after bariatric surgery. We have previously shown that a Facebook group administered by bariatric providers offers an effective alternative social support mechanism to in-person support groups, with higher patient participation. Our aim was to determine whether participation in this Facebook group could improve patient outcomes after bariatric surgery. Methods After institutional board approval, our center’s Facebook group members were electronically surveyed about their perceived value of group participation and their Facebook group usage frequency. We also collected patient age, sex, insurance, preoperative weight, type of procedure, hospital stay, postoperative complications, and weight loss from the electronic medical record. To assess the impact of Facebook group participation we compared patient outcomes between “frequent users” (those checking the Facebook group’s activity at least once a week), “infrequent users”, and a control group of all patients operated on during the year prior to the establishment of the Facebook group. The groups were compared after adjusting for potential confounding factors. Results 250 out of 1400 Facebook group patients responded to the survey (18%). 195 patients were frequent and 55 were infrequent users. Outcomes were compared with 211 control patients. The groups did not differ in their baseline characteristics apart from their sex. Frequent users had a higher weight loss compared to the other groups up to 2 years postoperatively but no difference in the overall complications. On multivariable analysis, frequency of Facebook use was the main factor associated with 0.5-, 1-, and 2-year weight loss. Conclusion Frequent participation in a Facebook support group after bariatric surgery was associated with improved early weight loss outcomes. If additional longer-term studies confirm our findings, offering similar social support groups may become essential after bariatric surgery, especially during times of social isolation when in-person social support meetings may not be feasible.

“…Research that has directly assessed PSS in MBS patients suggests that higher PSS levels are associated with a wide range of benefits including fewer surgical complications, greater weight loss, lower depression and disordered eating, and positive changes in PA. 5 , 10 , 11 , 12 , 13 Conversely, both quantitative and qualitative data suggest that deficits in PSS contribute to smaller weight losses, reduced surgery satisfaction and feelings of loneliness, struggle, and self‐blame during weight recurrence. 14 , 15 …”

ObjectiveGreater perceived social support (PSS) is associated with more favorable changes in weight loss, activity behaviors, and eating regulation after metabolic and bariatric surgery (MBS). However, studies have relied on generic, retrospective PSS measures, and stability of PSS levels and relations with weight loss and weight‐related behaviors over time is unknown. Using smartphone‐based Ecological Momentary Assessment, this study evaluated pre‐to 1‐year post‐MBS changes in daily weight management‐focused PSS and associations with weight loss, device‐measured activity behaviors, and eating regulation before and during the initial year after MBS.MethodAdult MBS patients (n = 71) received (1) an accelerometer to measure daily moderate‐to‐vigorous intensity physical activity (MVPA) and sedentary time (ST) minutes/day, and (2) a smartphone to complete morning weight‐focused PSS ratings and eating regulation (dietary restraint/disinhibition) ratings at four semi‐random times daily for 10 days at pre‐ and 3, 6, and 12‐month postoperative. Generalized linear mixed models analyzed the associations of PSS with total weight loss (%TWL) and activity/eating outcomes.ResultsParticipants on average reported relatively stable moderate‐to‐high PSS (3.98 on one to five scale) across assessments. Perceived social support was not related to %TWL, MVPA, or ST. Participants with higher PSS reported lower disinhibition and higher restraint than those with lower PSS (ps < 0.05); however, participants reported higher restraint on days that PSS was lower than their usual levels (p = 0.009).ConclusionsMBS patients on average had stable PSS levels across time. Higher PSS levels were associated with greater resistance to overeating cues (disinhibition) and cognitive control to restrict food intake (restraint) over time. Additionally, participants reported higher restraint when PSS levels were lower than usual. Overall, weight‐focused PSS appeared to hold greater importance in relation to regulating eating behavior than engaging in activity behaviors or weight loss among MBS patients during the initial postoperative year.Clinical Trial RegistrationNCT02777177.

“…Preoperative variables affecting postoperative weight loss include stress, social support, age, sex, preoperative body mass index (BMI), and diabetes status. [14][15][16] Early postoperative weight loss indicators, such as %EWL, are used to predict weight loss at 2-3 years. [17][18][19][20] Our previous study reported long-term efficacy prediction of LSG for morbid obesity in the Chinese population.…”

“…In fact, factors influencing the weight loss outcome after LSG include lifestyle, dietary habits, exercise, stress, social situation, and financial support. [14][15][16][44][45][46][47] Therefore, patients who could not achieve the desired early postoperative weight loss outcome, should make appropriate exercise, diet, and lifestyle changes to maintain the weight loss achieved by LSG in the long term. In addition, surgeons should pay more attention to these patients and help them eliminate factors not conducive to postoperative weight loss, including inappropriate postoperative diet and exercise habits.…”

Purpose To evaluate the predictive effect of the initial weight loss on the long-term weight loss in Chinese patients with a body mass index (BMI) ≥ 32.5 kg/m 2 who underwent LSG. Patients and Methods The follow-up was completed via phone or WeChat for outpatients and at the hospital for inpatients. We evaluated the BMI, percentage of excess weight loss (%EWL), and type 2 diabetes mellitus, hypertension, and hyperlipidemia statuses. Linear and logistic regression analyses were performed on the relationship between the initial and long-term weight loss. The optimal cut-off value was determined by receiver operating characteristic (ROC) curve analysis. Results We enrolled 307 patients, with a median preoperative BMI of 39.68 (35.68, 45.47) kg/m 2 . %EWL ≥ 50% was regarded as successful weight loss, and 76.55% of the patients lost their weight successfully. (Reviewer #1, comment #4) %EWL at 6 months and 5 years were positively correlated ( P < 0.001). Further, the following linear equation could express the relationship: (%EWL 5 years = 29.193 + 0.526 × %EWL 6 months ). %EWL ≥ 58.57% at 6 months was the best predictor of successful weight loss at 5 years after LSG (Reviewer #1, comment #5) (sensitivity, 73.62%; specificity, 73.61%; AUC value, 0.780). Internal verification of the prediction model revealed satisfactory results in terms of discrimination and calibration. Conclusion In Chinese patients with BMI ≥ 32.5 kg/m 2 who underwent LSG, %EWL at 6 months and 5 years were correlated. %EWL ≥ 58.57% at 6 months was a predictor of successful long-term weight loss.
