Levels of Physical Activity, Enjoyment, Self-Efficacy for Exercise, and Social Support Before and After Metabolic and Bariatric Surgery: a Longitudinal Prospective Observational Study. Obes Surg 2023; 33:3899-3906.

Abstract
INTRODUCTION Physical activity (PA) after metabolic and bariatric surgery (MBS) can influence weight loss, health status, and quality of life. Known mediators to participate in PA are enjoyment, self-efficacy, and social support. Little is known about PA behavior in MBS individuals. The aim of this study was to explore levels of PA and the PA mediators enjoyment, self-efficacy, and social support before and after MBS and to investigate changes over time. METHODS Adults scheduled to undergo MBS were recruited from a Swedish university hospital. Accelerometer-measured and self-reported PA, body weight, and PA mediators were collected at baseline and at 12 to 18 months post-surgery. RESULTS Among 90 individuals included, 50 completed the follow-up assessment and had valid accelerometer data. Sedentary time (minutes/day) was unchanged, but sedentary time as percentage of wear time decreased significantly from 67.2% to 64.5% (p<0.05). Time spent in light PA and total PA increased significantly from 259.3 to 288.7 min/day (p < 0.05) and from 270.5 to 303.5 min/day (p < 0.01), respectively. Step counts increased significantly from 6013 to 7460 steps/day (p < 0.01). There was a significant increase in self-reported PA, enjoyment, self-efficacy for exercise, and positive social support from family. The increase in PA mediators did not lead to a significant change in time spent in moderate to vigorous PA. CONCLUSION The increase in PA-mediators was not associated with an increase in moderate to vigorous PA, but the strengthened PA mediators suggest potential for an increase in moderate to vigorous PA in patients undergoing MBS.

Abstract
BACKGROUND Bariatric surgery is effective for patients with severe obesity, but relatively little is known about long-term functional outcomes. OBJECTIVE To describe physical fitness and activity changes among bariatric surgery patients in a clinical trial of physical activity interventions through 5 years postoperatively. SETTING Large bariatric center in the midwestern United States. METHODS Preoperatively, 6 months, and 5 years after surgery, 42 bariatric surgery patients wore an accelerometer to track activity and completed strength and cardiovascular endurance testing via treadmill, where estimated metabolic equivalents (METs) and ratings of perceived exertion (RPEs) were obtained. RESULTS Preoperatively, 25% of patients reported exertion of <3 METs (equivalent to walking 2.5 mi/hr) as an RPE of 16 ("hard to very hard"). This decreased significantly to approximately 5% of patients 6 months and 5 years after surgery. Before surgery, 7.5% achieved ≥6 METs (vigorous activity) at an RPE of 16. This increased significantly to 36.6% at 6 months and 42.1% at 5 years after surgery. Body mass index and age, but no physical activity measure, predicted functional ability over time. The steps/d and exercise bout min/wk increased significantly from before surgery to 6 months postoperatively (4886.5 to 5948.5 steps and 23.8 to 66.6 bout min), but increases were not maintained at 5 years (5677.7 steps and 41.4 bout min). Conversely, moderate to vigorous min/ d increased progressively from before surgery (17.4) to 6 months (32.3) and 5 years (48.1) postoperatively. CONCLUSIONS Functional abilities of bariatric surgery patients increased postoperatively and were maintained over 5 years. However, treadmill testing suggests that most patients are still unable to perform sustained activities of 6 METs (vigorous) or greater. Research is needed on bariatric patients' long-term function- and intervention- optimizing outcomes.

Abstract
Regular physical activity (PA) supports the long-term success of bariatric surgery. However, integrating health-enhancing physical activity in daily life requires specific competences. In this study, we evaluated a multimodal exercise programme to build these competences.Forty adults who underwent bariatric surgery were randomised to a multimodal exercise programme or control group. Primary outcomes were the facets of PA-related health competences, namely the control competence for physical training, PA-specific affect regulation, motivational competence and PA-specific self-control. Secondary outcomes were PA behaviour and subjective vitality. Outcomes were assessed before, directly after the intervention and at 3 months follow-up.Significant treatment effects were found for control competence for physical training and PA-specific self-control but not for PA-specific affect regulation and motivational competence. Significant treatment effects were further observed for self-reported exercise and subjective vitality, all in favour of the intervention group. In contrast, no treatment effect was found for device-based PA. Overall, this study provides a foundation for future research to optimise long-term post bariatric surgery outcomes.

Effectiveness of the perioperative encounter in promoting regular exercise and physical activity: a systematic review and meta-analysis. EClinicalMedicine 2023; 57:101806. [PMID: 36816345 PMCID: PMC9929685 DOI: 10.1016/j.eclinm.2022.101806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 12/04/2022] [Accepted: 12/07/2022] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND Low levels of physical activity (PA) are associated with poorer health outcomes. The perioperative encounter (extending from initial contact in primary care to beyond discharge from hospital) is potentially a good time to intervene, but data regarding the effectiveness of interventions are scarce. To address this, we systematically reviewed existing literature to evaluate the effectiveness of interventions applied perioperatively to facilitate PA in the medium to long-term (at least six months after the intervention). METHODS In this systematic review and meta-analysis, we searched Central Register of Controlled Trials (CENTRAL, Cochrane Library), MEDLINE, CINAHL, Embase, PsycInfo, and SPORTDiscus from database inception to October 22nd 2020, with an updated search done on August 4th 2022. We searched clinical trials registers, and conducted forward- and backward-citation searches. We included randomised controlled trials and quasi-randomised trials comparing PA interventions with usual care, or another PA intervention, in adults who were scheduled for, or had recently undergone, surgery. We included trials which reported our primary outcomes: amount of PA or whether participants were engaged in PA at least six months after the intervention. A random effects meta-analysis was used to pool data across studies as risk ratios (RR), or standardised mean differences (SMDs), which we interpreted using Cohen. We used the Cochrane risk of bias tool and used GRADE to assess the certainty of the evidence. This study is registered with PROSPERO, CRD42019139008. FINDINGS We found 57 trials including 8548 adults and compared 71 interventions facilitating PA. Most interventions were started postoperatively and included multiple components. Compared with usual care, interventions may slightly increase the number of minutes of PA per day or week (SMD 0.17, 95% CI 0.09-0.26; 14 studies, 2172 participants; I2 = 0%), and people's engagement in PA at the study's end (RR 1.19, 95% CI 0.96-1.47; 9 studies, 882 participants; I2 = 25%); this was moderate-certainty evidence. Some studies compared two different types of interventions but it was often not feasible to combine data in analysis. The effect estimates generally indicated little difference between intervention designs and we judged all the evidence for these comparisons to be very low certainty. Thirty-six studies (63%) had low risk of selection bias for sequence generation, 27 studies (47%) had low risk of bias for allocation concealment, and 56 studies (98%) had a high risk of performance bias. For detection bias for PA outcomes, we judged 30 studies (53%) that used subjective measurement tools to have a high risk of detection bias. INTERPRETATION Interventions delivered in the perioperative setting, aimed at enhancing PA in the medium to long-term, may have overall benefit. However, because of imprecision in some of the findings, we could not rule out the possibility of no change in PA.

JMIR Res Protoc 2022; 11:e39633.

Abstract
Background Regular physical activity (PA) is recommended to optimize weight and health outcomes in patients who have undergone metabolic and bariatric surgery (MBS). However, >70% of patients have low PA levels before MBS that persist after MBS. Although behavioral interventions delivered face-to-face have shown promise for increasing PA among patients who have undergone MBS, many may experience barriers, preventing enrollment into and adherence to such interventions. Delivering PA behavior change interventions via telehealth to patients who have undergone MBS may be an effective strategy to increase accessibility and reach, as well as adherence. Objective This paper reports the protocol for a study that aims to assess the feasibility and acceptability of the protocol or methods and the Telehealth Bariatric Behavioral Intervention (TELE-BariACTIV). The intervention is designed to increase moderate-to-vigorous intensity PA (MVPA) in patients awaiting bariatric surgery and is guided by a multitheory approach and a patient perspective. Another objective is to estimate the effect of the TELE-BariACTIV intervention on presurgical MVPA to determine the appropriate sample size for a multicenter trial. Methods This study is a multicenter trial using a repeated (ABAB’A) single-case experimental design. The A phases are observational phases without intervention (A1=pre-MBS phase; A2=length personalized according to the MBS date; A3=7 months post-MBS phase). The B phases are interventional phases with PA counseling (B1=6 weekly pre-MBS sessions; B2=3 monthly sessions starting 3 months after MBS). The target sample size is set to 12. Participants are inactive adults awaiting sleeve gastrectomy who have access to a computer with internet and an interface with a camera. The participants are randomly allocated to a 1- or 2-week baseline period (A1). Protocol and intervention feasibility and acceptability (primary outcomes) will be assessed by recording missing data, refusal, recruitment, retention, attendance, and attrition rates, as well as via web-based acceptability questionnaires and semistructured interviews. Data collected via accelerometry (7-14 days) on 8 occasions and via questionnaires on 10 occasions will be analyzed to estimate the effect of the intervention on MVPA. Generalization measures assessing the quality of life, anxiety and depressive symptoms, and theory-based constructs (ie, motivational regulations for PA, self-efficacy to overcome barriers to PA, basic psychological needs satisfaction and frustration, PA enjoyment, and social support for PA; secondary outcomes for a future large-scale trial) will be completed via web-based questionnaires on 6-10 occasions. The institutional review board provided ethics approval for the study in June 2021. Results Recruitment began in September 2021, and all the participants were enrolled (n=12). Data collection is expected to end in fall 2023, depending on the MBS date of the recruited participants. Conclusions The TELE-BariACTIV intervention has the potential for implementation across multiple settings owing to its collaborative construction that can be offered remotely.

Abstract
Postbariatric outcomes may improve by providing an additional preconditioning program (APP) in targeted patients. However, APPs are a demand for health resources while only little and inconsistent evidence consists to support their effectiveness. This cohort study aims to evaluate the effectiveness of APP, by comparing outcomes of patients with and without such APP. We carried out a retrospective single-centre cohort study in a before-after design. Patients signing up for primary gastric bypass or sleeve gastrectomy and eligible for surgery were included if screened as vulnerable patients. Vulnerable patients screened between September 2017 and March 2018 followed an APP and formed the APP-group. Due to a policy change, APPs were no longer performed since September 2018. Vulnerable patients screened between September 2018 and March 2019 thus did not receive an APP (comparator-group). Multidisciplinary follow-up remained unchanged. Endpoints included percentage total weight loss (%TWL), bodyweight, evolution of comorbidities, protein intake, and number of no-shows. The APP-group comprised 231 patients and the comparator-group 153. %TWL differed statistically significantly at 7 (Δ1.5%, p = .01) and 12 months postoperative (Δ2.8%, p < .01) in favour of the comparator-group, as did bodyweight 12 months postoperative (Δ1.8 kg, p < .01). Statistically significant differences were also found in the evolution of comorbidities, protein intake, and the number of no-shows, most in favour for the comparator-group. APP proofed not to be superior to Non-App. It is debatable whether statically significant differences are clinically relevant given their small magnitude. A care pathway without an APP seems at least as effective as a care pathway without.

Abstract
OBJECTIVE To systematically review the impact of prehabilitation on objectively measured physical activity (PA) levels in elective surgery patients. DATA SOURCES Articles published in Web of Science Core Collections, PubMed, Embase (Ovid), CINAHL (EBSCOHost), PsycInfo (EBSCOHost) and CENTRAL through August 2020. STUDY SELECTION Studies that met the following criteria: (1) written in English, (2) quantitatively described the effect(s) of a PA intervention among elective surgery patients prior to surgery and (3) used and reported objective measures of PA in the study. DATA EXTRACTION AND SYNTHESIS Participant characteristics, intervention details, PA measurement, and clinical and health-related outcomes were extracted. Risk of bias was assessed following the revised Cochrane risk of bias tool. Meta-analysis was not possible due to heterogeneity, therefore narrative synthesis was used. RESULTS 6533 unique articles were identified in the search; 21 articles (based on 15 trials) were included in the review. There was little evidence to suggest that prehabilitation is associated with increases in objectively measured PA, but this may be due to insufficient statistical power as most (n=8) trials included in the review were small feasibility/pilot studies. Where studies tested associations between objectively measured PA during the intervention period and health-related outcomes, significant beneficial associations were reported. Limitations in the evidence base precluded any assessment via meta-regression of the association between objectively measured PA and clinical or health-related outcomes. CONCLUSIONS Additional large-scale studies are needed, with clear and consistent reporting of objective measures including accelerometry variables and outcome variables, to improve our understanding of the impact of changes in PA prior to surgery on surgical and health-related outcomes.

Abstract
Bariatric surgery is the most efficacious treatment for obesity, though it is not free from complications. Preoperative conditioning has proved beneficial in various clinical contexts, but the evidence is scarce on the role of prehabilitation in bariatric surgery. We describe the protocol and pilot study of a randomized (ratio 1:1), parallel, controlled trial assessing the effect of a physical conditioning and respiratory muscle training programme, added to a standard 8-week group intervention based on therapeutical education and cognitive-behavioural therapy, in patients awaiting bariatric surgery. The primary outcome is preoperative weight-loss. Secondary outcomes include associated comorbidity, eating behaviour, physical activity, quality of life, and short-term postoperative complications. A pilot sample of 15 participants has been randomized to the intervention or control groups and their baseline features and results are described. Only 5 patients completed the group programme and returned for assessment. Measures to improve adherence will be implemented and once the COVID-19 pandemic allows, the clinical trial will start. This is the first randomized, clinical trial assessing the effect of physical and respiratory prehabilitation, added to standard group education and cognitive-behavioural intervention in obese patients on the waiting list for bariatric surgery. Clinical Trial Registration: NCT0404636.

Surg Obes Relat Dis 2020; 16:1994-2005. [PMID: 32919909 DOI: 10.1016/j.soard.2020.07.031] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 07/11/2020] [Accepted: 07/26/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Identifying psychosocial variables associated with physical activity may lead to the development of interventions that better address the challenges to participating in physical activity experienced by postbariatric surgery patients. OBJECTIVE To examine associations between select psychosocial variables and physical activity in patients who had undergone bariatric surgery within the past 2 years. SETTINGS Bariatric surgery candidates were recruited from the Greater Pittsburgh region. METHODS Eighty-three patients who had undergone bariatric surgery self-reported current physical activity and select psychosocial constructs. In addition, participants provided retrospective information on physical activity and psychosocial constructs before surgery. RESULTS Patients increased physical activity from baseline (median = 156.00 [25th, 75th percentiles: 53.00, 600.00] kcal/week) to post surgery (median = 976.00 [25th, 75th percentiles: 344.00, 1832.00] kcal/week) (P < .001). A number of pre- to postsurgery changes in psychosocial variables were associated with change in physical activity; however, only change in fitness orientation (P = .001), change in social support from friends (P = .005), and change in self-reported weight (P = .012) emerged as predictors of change in physical activity from pre- to postsurgery. Several postsurgery psychosocial factors were also significantly associated with postsurgery physical activity, but only postsurgery fitness orientation (P < .001), social support from co-workers (P = .002), and physical function (P = .023) emerged as predictive of the amount of postsurgical PA. CONCLUSIONS Pre- and postbariatric surgery interventions aimed at increasing physical activity participation may need to target important constructs that include the encouragement of social support and strategies to enhance the effort individuals put forward to engage in physical activity, as well as a focus on enhancing physical function and awareness of weight status.

Does intensive multidisciplinary intervention for adults who elect bariatric surgery improve post-operative weight loss, co-morbidities, and quality of life? A systematic review and meta-analysis. Obes Rev 2020; 21:e13012. [PMID: 32196906 DOI: 10.1111/obr.13012] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Revised: 01/30/2020] [Accepted: 02/08/2020] [Indexed: 12/14/2022]
Abstract
This systematic review and meta-analysis of intervention studies aims to evaluate the effect of preoperative and/or post-operative support for adults who elect bariatric surgery delivered by a multidisciplinary team (MDT) on post-operative body composition, mental health, co-morbidities, quality of life, and side effects. Six electronic databases were searched. Revman and GRADE were used to assess confidence in pooled effects. Included interventions (N = 1533 participants in total) focused on lifestyle counselling (n = 4 studies), psychology (n = 4 studies), or exercise (n = 10 studies); comparator groups were less intensive usual care. Intensive MDT interventions increased post-operative weight loss (SMD: -0.94; 95% CI: -1.27 to -0.61) if delivered post-operatively. Preoperative and post-operative intensive interventions improved symptoms of depression and anxiety, quality of life, diastolic blood pressure, and resting heart rate but not lipids or glycaemic measures. Whilst usual MDT care is important preoperatively, this review conditionally recommends intensive MDT interventions for enhanced post-operative weight loss if delivered in the post-operative period, led by any health professional, based on moderate evidence. This review also conditionally recommends preoperative and/or post-operative lifestyle, nutrition, or psychology counselling and/or physical activity for improved mental and physical health. Further randomized controlled trials are required, which aim to specifically evaluate the best use of MDT resources.

Abstract
BACKGROUND We have previously reported on the benefits of Pre-Surgical Exercise Training (PreSET) on physical fitness and social interactions in subjects awaiting bariatric surgery (BS). However, data are needed to know whether these benefits are maintained post-BS. OBJECTIVES The purpose of this paper was to evaluate the effect of PreSET on physical activity (PA) level, physical fitness, PA barriers, and quality of life (QoL) 1 year (1-Y) after BS. METHODS Of the 30 participants randomized into two groups (PreSET and usual care), 25 were included in the final analysis. One year after BS, time spent in different PA intensities and number of steps were assessed with an accelerometer. Before BS and until 1-Y after BS, physical fitness was assessed with symptom-limited cardiac exercise test, 6-min walk test (6MWT), and sit-to-stand, half-squat, and arm curl tests. QoL, PA barriers, and PA level were evaluated with questionnaires. RESULTS The number of steps (7460 vs 4287) and time spent in light (3.2 vs 2.2 h/day) and moderate (0.6 vs 0.3 h/day) PA were higher in the PreSET group 1-Y after BS. The changes in 6MWT heart cost (1.3 vs 0.6 m/beats/min), half-squat test (38.8 vs 10.3 s), and BMI (- 16.8 vs - 13.5 kg/m2) were significantly greater in the PreSET group compared to those in the usual care group. No other significant difference between groups was observed. CONCLUSION The addition of the PreSET to individual lifestyle counseling seems effective to improve PA level and submaximal physical fitness 1-Y after BS. Studies with larger cohorts are now required to confirm these results. The trial was registered at clinicaltrials.gov (NCT01452230).

A qualitative study. Obes Res Clin Pract 2017; 12:307-316. [PMID: 29150223 DOI: 10.1016/j.orcp.2017.11.001] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Revised: 10/21/2017] [Accepted: 11/03/2017] [Indexed: 12/31/2022]
Abstract
AIMS To explore participants' ability to participate in physical activity (PA), and barriers and facilitators to PA, at 12 months following restrictive bariatric surgery, and how these differed from participants' pre-surgery perceptions. Motivators for PA post-surgery were also explored. METHODS Qualitative one-on-one in-depth interviews were conducted pre- and 12 months post-surgery. Data were analysed using inductive thematic analysis. RESULTS Fourteen adults (12 females), with a mean (range) age of 41.4 years (25.0-56.0), body mass index (BMI) of 31.7kg/m2 (22.3-48.2), and excess weight loss of 66% (2-127) completed both interviews. Lack of participation in PA during the first 3-6 months post-surgery was a common theme. Although participants reported increased ability to participate in PA, attributing this to a reduction in obesity-related physical barriers to PA, many participants reported that some pre-surgery obesity-related barriers to PA remained at 12 months post-surgery. For most participants, pre-surgery non-obesity related barriers to PA also remained at 12 months post-surgery. Facilitators to PA were consistent pre- and post-surgery. Weight loss and improvement in physical appearance were the most common motivators for PA post-surgery. CONCLUSIONS At 12 months following surgery, many participants reported residual obesity and non-obesity related barriers to PA. These barriers may explain the small, if any, pre- to post-surgery change in PA levels reported by earlier research. Facilitators to PA did not change and post-surgery motivators for PA were mostly esteem-related. These data are relevant to shape interventions aimed at optimising PA in this population.

Abstract
Physical activity is an important factor for the maintenance of health. Enjoyment of physical activity is essential to motivate persons to engage in sufficient physical activity. We examined whether self-reported enjoyment of PA is associated with objective measurement of the intensity of PA. A cardiovascular examination program was provided for individuals aged 40-75 years without a history of cardiovascular events in Greifswald, Germany between 2012 and 2013. Participants (n = 255) were asked to wear a three-axial accelerometer device (ActiGraph, GT3X +, Pensacola, Florida, USA) for 7 consecutive days. After wearing the device, the participants were asked to complete the 18-item self-administered physical activity enjoyment scale (PACES). Participants' (n = 200) daily minutes of moderate-to-vigorous physical activity (MVPA) and their enjoyment of PA were analysed in a linear regression approach. The mean age of the participants was 56.3 ± 9.7 years, 41.0% were male. The average MVPA duration was 44.4 ± 27.3 min per day. In the regression analysis, enjoyment of PA was positively associated with MVPA (β = 0.18, 95% CI (0.05; 0.31), p = 0.009), participants with higher enjoyment of PA showed higher MVPA. We found a positive association between MVPA and enjoyment of PA, although for male participants only. Between bouted MVPA and enjoyment of PA there was no significant relationship.
