“…Previous studies, using self-reported questionnaires, have shown that bariatric surgery patients increase, often with over 20%, their time spent in MVPA post-surgery [9]. In contrast, when bariatric patients have worn objective physical activity measures, such as accelerometers, the results show that overall physical activity and MVPA do not increase [19][20][21][22][23][24][25], or increase to a small extent after surgery [26]. Only a few studies have evaluated the discrepancies between self-reported and accelerometer-measured physical activity pre-to postsurgery within the same individuals [19,23,27].…”

“…A study by Bergh et al showed a high prevalence of overestimating the time spent in MVPA, assessed by selfadministered questionnaire, compared with objective- measured MVPA up to 24 months post-surgery, but, no objective data at pre-surgery were available to be able to compare the difference from pre-to post-surgery. However, their results showed a high over-reporting of time spent in MVPA, where 80% of the participants reported to have met the weekly MVPA guidelines, while according to objective measures the prevalence was only 17.9% [24]. People with obesity tend to overestimate their MVPA levels [28,35] and also misclassify the intensity of physical activity to a higher extent than people of normal weight [35].…”

Background: Roux-en-Y Gastric Bypass (RYGB) patients overestimate their time spent in moderate-to-vigorous physical activity (MVPA) to a greater extent post-surgery than pre-surgery. However, there is no data on discrepancy between self-reported and accelerometer-measured MVPA beyond nine months post-RYGB. The aim was to investigate how the duration of MVPA (main outcome) differs when comparing a self-administered questionnaire to accelerometer-data from pre-surgery and up to 48 months post-RYGB. Methods: Twenty-six (38%) RYGB-treated women with complete data from the original cohort (N = 69) were included. Participants were recruited from five Swedish hospitals. Mean pre-surgery BMI was 38.9 (standard deviation (SD) = 3.4) kg/m 2 and mean age 39.9 (SD = 6.5) years. MVPA was subjectively measured by a selfadministered questionnaire and objectively measured by the ActiGraph GT3X+ accelerometer at 3 months pre-RYGB and 9-and 48 months post-RYGB. Means and SD were calculated at 3 months pre-and 9-and 48 months post-RYGB. We calculated the P-values of the differences with Wilcoxon Signed-Rank test. For correlations between the self-administered questionnaire and the accelerometers, Spearman's rank correlation was used. Results: Participants significantly overestimated (i.e. self-reported more time spent in MVPA compared to accelerometry) their MVPA in a higher degree post-compared to pre-RYGB surgery. Compared to pre-surgery, selfreported MVPA increased with 46.9 and 36.5% from pre-to 9-and 48 months, respectively, whereas changes were a 6.1% increase and 3.5% decrease with accelerometers. Correlations between self-reported and accelerometermeasured MVPA-assessments were poor at all measurement points (r = 0.21-0.42) and only significant at 48 months post-RYGB (P = 0.032). Conclusions: The discrepancy between self-reported and objectively assessed MVPA within the same individual is greater up to 48 months post-RYGB compared to before surgery. To help bariatric patients understand and hopefully increase their physical activity behaviors post-surgery, objective measures of physical activity should be used.

“…In recent years, few studies have shed light on the factors influencing PA participation in bariatric patients. For instance, Bergh, Kvalem, Mala, Hansen, and Sniehotta (2017) showed that being single, higher education level, and greater self-regulation predicted PA. Reid et al (2016) indicated that neighbourhood walkability did not influence either daily steps or sedentary time. From a qualitative perspective, Wiklund, Fagevik, Olbers, and Willén (2014) pointed out that some physical side effects of bariatric surgery, such as diarrhoea or excess skin, prevented patients from being as active as they would like to be.…”

Purpose: Physical activity (PA) is considered essential for the treatment of morbid obesity and the optimization of bariatric surgery outcomes. The objective of this article was to identify the facilitators and barriers that bariatric patients perceived to do PA one year after finishing a PA programme for the promotion of a long-term active lifestyle. This objective was addressed from a socio-ecological and qualitative perspective. Methods: Nine patients (eight women and one man), aged between 31 and 59 years, participated in semi-structured interviews directly following the PA programme and one year after it. A content analysis was carried out to analyze the qualitative data. Results: Weight loss, improvement of physical fitness, perceived competence, and enjoyment were the main facilitators of PA. Complexes related to skin folds, osteoarthritis, perceived unfavourable weather conditions, lack of social support and economic resources, long workdays, lack of specific PA programmes, and other passive leisure preferences were the main barriers to participate in PA. Conclusions: Results highlight the important interplay between personal, social environmental, and physical environmental factors to explain (in)active behaviours of bariatric patients. The findings of this article could be useful for future research and interventions aimed at promoting PA in bariatric patients.

“…Therefore, bariatric patients are advised to engage in regular physical activity [8][9][10][11]. Previous studies indicate that low physical activity after bariatric surgery is related to less weight loss and more weight regain [12][13][14], though more recent studies question whether weight loss is positively influenced by adherence to a healthy lifestyle with regular physical activity [15,16].…”

Weight Change After Roux-en Y Gastric Bypass, Physical Activity and Eating Style: Is There a Relationship?

et al. 2018

Background Insufficient weight loss and weight regain is seen in 20-30% of the post-bariatric population. More knowledge about the effect of physical activity and eating style on weight change after Roux-en-Y gastric bypass is essential since behaviour can be modified and thereby results improved. The goal of this study is to determine the relationship between weight change, selfreported physical activity and eating style. Methods Weight, physical activity (PA) and eating style (ES) were assessed before surgery and 15, 24, 36 and 48 months after surgery. A linear mixed model was performed to assess the association between the change in PA and ES and percentage total weight loss (% TWL). Results There were 4569 patients included. Preoperative PA and ES were not related to weight change. Change in PA was positively associated with % TWL at 15, 36 and 48 months follow-up. Change in emotional eating was negatively related to % TWL at all follow-up moments. Change in external eating was only negatively related to weight loss at 24 months follow-up. Change in restrained eating was negatively associated with weight loss up to 36 months follow-up. More restrained eating at 36 months follow-up was related to higher weight regain, and more emotional eating at 48 months to 48-month weight regain. Conclusion Preoperative self-reported PA and ES did not predict weight change after RYGB. Being are more physically active and showing less emotional and restrained eating was related to a higher weight loss. Emotional and restrained eating were related to higher weight regain.
