“…Previous studies show that this objective can be difficult to achieve. Neither group-based educational programs of four to ten sessions, nor a motivational individual PA intervention for 6 months resulted in increased PA [ 39 – 41 ]. An intervention focusing on mediators for PA, motivational theories, and how habits are formed may be more successful.…”

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.

Purpose Obesity surgery and polycystic ovary syndrome (PCOS) are both associated with increased risk of intrauterine growth restriction. We investigated whether offspring of mothers with PCOS who underwent obesity surgery had an increased risk of deviating birth anthropometrics compared to offspring of mothers without PCOS. Methods In this observational study, data from two study databases (BAROBS and PregMet2) were supplemented with data from patient’s records from secondary and tertiary hospitals. In total, 162 offspring born to mothers with PCOS (n = 48) and without PCOS (n = 114) were included. Forty-nine offspring were born prior to, and 113 after obesity surgery. Results Mean ± SD birthweight (BW), birth length (BL), and head circumference (HC) before and after surgery for offspring born to mothers with PCOS were 3987 ± 495 g vs 3396 ± 526 g (P = 0.001), 52.2 ± 1.6 cm vs 50.1 ± 2.2 cm (P = 0.010), and 36.3 ± 1.97 cm vs 35.3 ± 1.66 cm (P = 0.183), respectively. In the non-PCOS group BW, BL and HC before and after were 3859 ± 603 g vs 3490 ± 538 g (P = 0.001), 51.3 ± 2.0 cm vs 49.9 ± 2.5 cm (P = 0.013), and 36.4 ± 2.0 cm vs 35.3 ± 1.8 cm (P = 0.016), respectively. Post-surgery, we found no difference in z-score BW, (∆–0.08, P = 0.677), BL (∆0.21, P = 0.184), and HC (∆0.14, P = 0.476) between children of PCOS and non-PCOS mothers. Comclusion Babies born after obesity surgery were smaller and shorter in both the PCOS and non-PCOS group. Post-surgery anthropometrics were similar in babies born to mothers with and without PCOS.

Introduction Identifying eating behaviors associated with suboptimal weight loss following bariatric surgery remains important. This study assessed the relationship between eating behaviors and weight loss following bariatric surgery in a racially diverse sample. Methods Participants were assessed before surgery and 6 and 12 months postoperatively, with the Structured Clinical Interview for DSM-5, the Eating Disorder Examination-Bariatric Surgery Version, and validated measures assessing a range of eating behaviors. Linear mixed effect models were used to test the impact of eating behaviors on percent weight loss (%WL) at 6 and 12 months. Results We enrolled 300 participants (mean age 40.1 years; BMI 45.9 kg/m 2 ; 87% women; 62% Black and 30% White). The majority (82%) underwent sleeve gastrectomy (SG). Mean %WL was 23.0 ± 5.1% at 6 months and 26.2 ± 7.6% at 12 months. Subjective binge episodes prior to surgery predicted greater %WL over the first 12 postoperative months ( p = 0.028). Postoperative disinhibition, hunger, night eating symptoms, objective binge episodes, global disordered eating attitudes and behaviors, and snacks per day were associated with smaller %WL over 12 months (all p’s < 0.01). The presence of picking/nibbling and addictive-like eating behaviors was not associated with %WL at the end of the first postoperative year. Conclusion Among a diverse participant sample, problematic eating behaviors following surgery were associated with smaller %WL over 12 months. Postoperative assessment and treatment of eating behaviors are needed to address these issues as they arise and to prevent attenuation of early weight loss in some patients. Graphical Abstract
