Social History of Bariatric Surgery: Relationship to Patient and Associations with Postoperative Outcomes.

PURPOSE: There is limited research about the prevalence of patients initiating metabolic and bariatric surgery (MBS) who also know someone who had MBS, referred to as having a social history of MBS. Evidence about the specific relationship of these individuals to the patient, how having a social history of MBS is associated with patients' choice of surgical procedure, and how having a social history of MBS is associated with patients' postoperative outcomes can be used to inform future preoperative assessments. The objective was to (a) define the number of people patients knew who had MBS and relationship to patient, (b) assess congruence between those who had MBS with patients' procedure selection, and (c) explore associations between social history of MBS and postoperative outcomes. MATERIALS AND METHODS: The sample included 123 patients who had MBS in 2021 (83.7% female; 44.7% Sleeve Gastrectomy, 55.3% Gastric Bypass). For up to 5 people, patients provided their relationship and surgical procedure, and completed the Family Assessment Device (FAD). Bivariate analyses assessed congruence in type of procedure, and social history of MBS with complications, readmissions, and %TWL. Three mixed multilevel models were conducted with (1) close friend, (2) coworker, and (3) close family history of MBS including the FAD on change in %TWL over 12 months with surgical procedure as a covariate. RESULTS: Ninety-one percent of patients knew someone who had MBS, average 2.66±1.45. Patients reported a close friend (56.1%), close family member (43.9%), and coworker (19.5%) who had MBS. Patients with a close family member who had MBS and reported healthy vs impaired family functioning had greater %TWL over 12 months (p=0.016). Patients with a close friend who had MBS had less %TWL (p=0.015), and patients with a coworker who had MBS had greater %TWL (p=0.012), which did not change over time. CONCLUSION: Patients with coworkers or close family members with healthy family functioning with a history of MBS had more weight loss, whereas those with close friends with a history of MBS had less weight loss.

Associations between psychological evaluation outcomes, psychiatric diagnoses, and outcomes through 12 months after bariatric surgery.

BACKGROUND: There is limited evidence about how patients' initial preoperative psychological evaluation outcomes (require follow-up [RFU], no required follow-up [NFU], and place on hold [POH]) and current psychiatric diagnoses associate with postoperative outcomes. OBJECTIVES: To test the hypotheses that patients who receive a clinical decision of RFU versus NFU from their initial psychological evaluation will be (1) more likely to experience postoperative complications, readmissions, and emergency room visits and (2) experience less weight loss over 12-months. Specific diagnoses (any psychiatric diagnosis, depression, and anxiety) are also examined for their association with weight loss over 12 months. SETTING: Midwestern medical center, United States. METHODS: The sample included 322 patients (81.1% female and 64.0% White) with completed psychological evaluations between August 2019 and December 2020. Patient demographics, psychological evaluation outcomes, current diagnoses, and postoperative outcomes were extracted from the health record. Bivariate analyses determined associations between NFU/RFU and postoperative complications (yes, no), readmissions (yes, no), and emergency room visits (yes, no). Mixed multilevel models were conducted with dichotomous variables NFU/RFU, any psychiatric diagnoses (yes, no), depression diagnoses (yes, no), or anxiety diagnoses (yes, no) as the main fixed within-group factors with weight loss (weight or percent total weight loss) used as the repeated measures. Insurance and surgical procedure were included as covariates. RESULTS: There were no significant differences in postoperative complications, readmissions, and emergency room visits between NFU and RFU groups. Patients who received a RFU versus an NFU had higher weights over 12 months (P = .001). CONCLUSION: Hypothesis 2 was only partially supported. Patients who received an RFU versus an NFU had higher weights over 12 months, but this association was not found for percent total weight loss or any of the psychiatric within-subjects variables (i.e., psychiatric diagnoses, depression, and anxiety).

Changes in Child Weight, Behaviors, and Family Dynamics during Parental Participation in a Medical Weight Management Program: A Longitudinal Uncontrolled Pilot Study.

Background: There is limited evidence of the effects of parental participation in outpatient medical weight management (MWM) programs on children. The aims of the project were to (1) identify time effects from parental participation in the MWM program on changes in child weight trajectories, healthy and unhealthy weight control practices, physical and sedentary activity, parental restrictive feeding and pressure to eat, and family functioning and communication and (2) determine differences based on child factors. Methods: A longitudinal uncontrolled pilot study was conducted, in which parent-child (ages 7-19) dyads completed assessments at parents' MWM program initiation, 3 months (mid-program), 6 months (end of program), and 12 months to determine sustained effects. Repeated measures analysis of variance (ANOVA) was completed using a mixed multilevel modeling approach using Restricted Maximum Likelihood estimation method; each outcome was additionally analyzed with child baseline weight status, age group, and sex as between-subjects factors. Results: Fifty three dyads met inclusion criteria, 23 completed the initial assessment (enrollment: 43.3%), and 13 completed the 12-month assessment (retention: 56.5%). Significant effects over time were observed for decreased parental restrictive feeding (p < 0.038) over 12 months, and group by time effects were observed for increased restrictive feeding for female compared to male children (p = 0.025) over 12 months. Marginally significant group by time effects were found for increased impaired family functioning (p = 0.054) and communication (p = 0.054) for children with overweight/obesity compared to healthy weight children over 12 months. Conclusions: Female children and children with overweight/obesity may experience increased negative family dynamics (restriction of food, family functioning, and communication) through parental MWM programs.

Preoperative Psychological Evaluation Outcomes, Reasoning, and Demographic and Diagnostic Correlates.

PURPOSE: Little is known about associations between preoperative psychiatric, disordered eating, and substance use diagnoses with the clinical decision to require follow-up after the preoperative psychological evaluation. To determine the proportion of patients who require follow-up (no required follow-up (NFU), required follow-up (RFU), placed on hold (POH)) from the preoperative psychological evaluation, associations with diagnoses, and noted reasons for follow-up. MATERIALS AND METHODS: The sample included 508 patients (77.6% female; 64.4% White) pursuing bariatric metabolic surgery with completed psychological evaluations between August 2019 and December 2020 at a Midwest medical center. Patient demographics, psychological evaluation outcome and corresponding reasoning, and psychiatric, disordered eating, and substance use diagnoses were extracted from the health record. Descriptive and bivariate analyses determined associations between demographics and diagnoses with psychological evaluation outcomes and corresponding reasoning. RESULTS: The breakdown of psychological evaluation outcomes was 60.6% (n = 308) NFU, 38.4% (n = 195) RFU, and 1.0% (n = 5) POH. Demographic correlates of RFU included higher BMI, being single, lower educational attainment, unemployment, public/no insurance, and receiving multiple or any psychiatric diagnosis (all p-values < 0.05). Diagnostic correlates of RFU included anxiety, depression, not having a current trauma or stressor-related disorder, disordered eating, and substance use diagnoses (all p-values < 0.001). RFU/POH was primarily due to psychiatric (61%) reasons. CONCLUSION: Higher rates of RFU were observed for patients with higher economic need and with psychiatric, disordered eating, or substance use diagnoses. Future work should establish preoperative programming to assist patients with addressing ongoing psychiatric concerns prior to bariatric metabolic surgery.

Parents' Reports of Children's Physical and Sedentary Behavior Engagement among Parents in Weight Management.

Background: The purpose of this study was to explore the associations between demographics, family exercise participation, family discouragement of exercise, and the children's physical and sedentary behaviors to identify specific areas of physical activity intervention for children with parents engaged in medical weight management (MWM). Methods: Parents (n = 294) of children aged 2−18 years old were recruited from two university MWM programs to complete a one-time survey. Bivariate analyses tested associations. Results: Parents reported that sedentary activity was higher for children who identified as racial minorities (t(141) = −2.05, p < 0.05). Mobile phone and tablet use was higher for adolescents compared to school age and young children (H(2) = 10.96, p < 01) Exercise game use was higher for racial minority children compared to white children (U = 9440.5, z = 2.47, p ≤ 0.03). Male children (t(284) = 1.83, p < 0.07), children perceived to have a healthy weight status (t(120) = 4.68, p < 0.00), and younger children (t(289) = 1.79, p < 0.08) all engaged in more strenuous physical activity. Family exercise participation (t(162) = −2.93, p < 0.01) and family discouragement of exercise (U = 7813.50, z = −2.06, p ≤ 0.04) were significantly higher for children in racial minority families. Conclusions: Future work should determine methods to engage children and their parents participating in MWM in physical activities together to ensure that the changes the parents are making with MWM are sustainable.

Patient Access, Utilization, and Perceptions of Neighborhood and Built Environment Resources.

PURPOSE: There is a critical need to explore bariatric patients' perceptions of existing neighborhood and built environment resources and supports to assist with postoperative behavior change and weight loss maintenance. The objective of this study was to survey postoperative patients to determine neighborhood food retail, fitness facility, and options for outdoor activity access, utilization, satisfaction, and perceptions of resources. MATERIALS AND METHODS: A convenience sample of postoperative patients from a single academic surgical center in the USA (N = 44) completed an online survey about access, utilization, satisfaction, and safety for food retail, fitness facility, and outdoor activity options in their neighborhoods. Analysis included descriptives (frequency, percent, Chi-square), and independent samples t tests and ANOVA determined differences based on race, insurance status, geographic location, and receipt of governmental assistance programs. Open-ended questions were analyzed using summative content analysis. RESULTS: Patients reported the highest access to lower-cost national food retailers and fitness facilities. The most prevalent challenge in finding food products to meet patients' goals was financial (39%). Patients' top suggestions for fitness facilities included training staff/facilities (59%) and trainers (35%) in postoperative patient care and exercise. The highest access for outdoor activity options was for walking/running trails, city/metro parks, and sidewalks. Significant differences in access, utilization, and safety were found based on geographic location, receipt of at least one assistant program, and race. CONCLUSION: The development of targeted resources may benefit patients in non-suburban areas and who receive governmental assistant programs to increase safety of outdoor options and access to lower-cost food retailers and to increase utilization of lower-cost fitness facilities.

Changes in Parent and Child Skin Carotenoids, Weight, and Dietary Behaviors over Parental Weight Management.

(1) The objective was to determine changes in parent-child (ages 7-18) dyad skin carotenoids spanning parental participation in a medical weight management program (WMP), and associations with parent BMI, child BMIz, fruit/vegetable intake, and family meals and patterns. (2) The study design was a longitudinal dyadic observational study with assessment at WMP initiation, mid-point (3-months), and conclusion (6-months). Twenty-three dyads initiated the study, 16 provided assessments at 3 months, and 11 at program conclusion. Associations between parent and child carotenoids (dependent variables) and parent BMI, child BMIz, increases in fruit/vegetable intake, and family meals and patterns were analyzed using Pearson's correlations and independent samples t-tests. Repeated measures ANOVA assessed changes in weight status and carotenoids. (3) Parents experienced significant declines in BMI and skin carotenoid levels over 6 months. Parent and child carotenoids were correlated at each assessment. At initiation, parent BMI and carotenoids were inversely correlated, child carotenoids were associated with increased family meals, and never consuming an evening fast food or restaurant meal were associated with increased parent and child carotenoids. (4) Results demonstrate skin carotenoids are strongly correlated within dyads and may be associated with lower parental BMI and positive family meal practices.

Impaired Family Functioning Affects 6-Month and 12-Month Postoperative Weight Loss.

PURPOSE: Prior cross-sectional research details the high rate of impaired family functioning, a measure of the overall family environment, among adult bariatric surgery patients; however, family functioning has not been explored in relation to adult patient's postoperative outcomes. The objective of this study was to determine how family functioning affects postoperative patient outcomes including readmission rates, early complications, and 6- and 12-month percent total weight loss (%TWL). MATERIALS AND METHODS: An observational design at a single-academic medical center was employed. The sample comprised 98 patients, living with ≥1 family member, who enrolled in one of two concurrent studies at the Center. Patients were followed from their surgical intake through 12 months postsurgery; family functioning was assessed within 2 months of their date of surgery. Chi-square and independent t tests determined significant associations between family functioning with readmission and complication rates. Average family functioning was an independent variable in multivariate linear regression models to determine significant correlates of %TWL at 6 and 12 months postsurgery. Patient age, race, and insurance status were included as covariates. RESULTS: Patients with higher impaired family functioning had significantly less %TWL at 6 (p=.004) and 12 months (p=.030). Black patients also had significantly lower %TWL at 6 (p=.003) and 12 months (p=.009). CONCLUSION: Family functioning and patient race were both correlates of weight loss at 6 months and 12 months. Future research should explore additional family factors as correlates of patient outcomes following bariatric surgery.

Brief Report: Bariatric Surgery Patients' Communication and Engagement in Activities with Their Children.

Children witness parental weight loss from bariatric surgery; however, little is understood about parental engagement and communication with children about weight loss. The purpose of this study is to explore parental engagement in activities and communication about weight loss with children during the bariatric surgery process. Seventy-two pre- or post-surgery parents, living with a child 2-25- years- old, were surveyed using a questionnaire to assess engagement in social and physical activities and communication with children about weight loss, and the Social Support for Exercise and Eating Habits Survey. Multivariate logistic regression determined correlates of engagement and communication, with covariates: child age and perceived weight status, surgery status, and social support. Family discouragement for making eating habit change was associated with an increased odds [OR = 1.21 (CI 1.03, 1.41)] of parents endorsing their weight held them back from social activities. Parents with older children [OR = .88 (CI .78, 1.00)] and children perceived to have overweight/obesity [OR = .18 (CI .03, .96)], and who were post-surgery [OR = 4.78 (CI 1.05, 21.88)] had increased odds of discussing losing weight with their child. The results of this study suggest parents are communicating with their children about weight loss, though more often with older and overweight/obese children.
