- Background: To optimize postoperative outcomes after bariatric surgery, lifestyle changes including increased physical activity are needed. Micronutrient deficiency after surgery is also common and daily supplementation is recommended. Objective: The aim of the PromMera study is to evaluate the effects of a 12-week smartphone app intervention on promotion of physical activity (primary outcome) and adherence to postsurgery vitamin and mineral supplementation, as well as on other lifestyle factors and overall health in patients undergoing bariatric surgery. Methods: The PromMera study is a two-arm, randomized controlled trial comprising patients undergoing bariatric surgery. Participants are randomized postsurgery 1:1 to either the intervention group (ie, use of the PromMera app for 12 weeks) or the control group receiving only standard care. Clinical and lifestyle variables are assessed pre- and postsurgery after 18 weeks (postintervention assessment), 6 months, 1 year, and 2 years. Assessments include body composition using Tanita or BOD POD analyzers, muscle function using handgrip, biomarkers in blood, and an extensive questionnaire on lifestyle factors. Physical activity is objectively measured using the ActiGraph wGT3X-BT triaxial accelerometer. Results: A total of 154 participants have been enrolled in the study. The last study participant was recruited in May 2019. Data collection will be complete in May 2021. Conclusions: Implementing lifestyle changes are crucial after bariatric surgery and new ways to reach patients and support such changes are needed. An app-based intervention is easily delivered at any time and can be a key factor in the adoption of healthier behavioral patterns in this rapidly growing group of patients.

- Purpose Ways to motivate and support patients in being physically active after bariatric surgery are needed. This trial was aimed at evaluating the effect of using a smartphone application targeting physical activity during 12 weeks on moderate-to-vigorous physical activity (MVPA, primary outcome) and secondary outcomes of inactivity, light physical activity (LPA), body mass index (BMI), and percent total weight loss (%TWL) after bariatric surgery.Materials and Methods Data from a randomized controlled trial comprising 146 patients (79.5% women) undergoing bariatric surgery was analyzed. Mean age and BMI pre-surgery were 40.9 years and 40.5 kg/m(2), respectively. Participants were randomized 1:1 to an intervention or a control group. Physical activity and body weight were objectively measured at baseline pre-surgery and post-surgery follow-ups after 6 weeks (weight only), 18 weeks, 6 months, and 1 year. Linear mixed models were fitted to assess longitudinal differences in outcomes between the groups.Results A significant effect of the intervention (group-by-time interaction 16.2, 95% CI 3.5 to 28.9) was seen for MVPA at 18 weeks; the intervention group had increased their MVPA since baseline, while the control group had decreased their MVPA. The control group had lowered their BMI approximately 1 kg/m(2) more than the intervention group at follow-up after 18 weeks and 12 months, yet, mean BMI did not differ between the groups. No intervention effect was seen on inactivity, LPA, or %TWL.ConclusionOur results indicate that use of a smartphone application targeting physical activity may have the potential to promote short-term MVPA post bariatric surgery.

- IMPORTANCE: Laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) are widely used bariatric procedures for which comparative efficacy and safety remain unclear.OBJECTIVE: To compare perioperative outcomes in SG and RYGB.DESIGN, SETTING, AND PARTICIPANTS: In this registry-based, multicenter randomized clinical trial (Bypass Equipoise Sleeve Trial), baseline and perioperative data for patients undergoing bariatric surgery from October 6, 2015, to March 31, 2022, were analyzed. Patients were from university, regional, county, and private hospitals in Sweden (n = 20) and Norway (n = 3). Adults (aged ≥18 years) eligible for bariatric surgery with body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared) of 35 to 50 were studied.INTERVENTIONS: Laparoscopic SG or RYGB.MAIN OUTCOMES AND MEASURES: Perioperative complications were analyzed as all adverse events and serious adverse events (Clavien-Dindo grade >IIIb). Ninety-day mortality was also assessed.RESULTS: A total of 1735 of 14 182 eligible patients (12%; 1282 [73.9%] female; mean (SD) age, 42.9 [11.1] years; mean [SD] BMI, 40.8 [3.7]) were included in the study. Patients were randomized and underwent SG (n = 878) or RYGB (n = 857). The mean (SD) operating time was shorter in those undergoing SG vs RYGB (47 [18] vs 68 [25] minutes; P < .001). The median (IQR) postoperative hospital stay was 1 (1-1) day in both groups. The 30-day readmission rate was 3.1% after SG and 4.0% after RYGB (P = .33). There was no 90-day mortality. The 30-day incidence of any adverse event was 40 (4.6%) and 54 (6.3%) in the SG and RYGB groups, respectively (odds ratio, 0.71; 95% CI, 0.47-1.08; P = .11). Corresponding figures for serious adverse events were 15 (1.7%) for the SG group and 23 (2.7%) for the RYGB group (odds ratio, 0.63; 95% CI, 0.33-1.22; P = .19).CONCLUSIONS AND RELEVANCE: This randomized clinical trial of 1735 patients undergoing primary bariatric surgery found that both SG and RYGB were performed with a low perioperative risk without clinically significant differences between groups.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02767505.

- ObjectiveFew studies have been carried out concerning the influence of bariatric surgery on female sexuality and hormones, particularly utilizing hormone-based questionnaires. The effect of bariatric surgery on sex hormone levels, sexual function and health-related quality of life (HRQL) in women was analyzed in this study. Participants were included in a single-center study at a regional hospital in Sweden, with a duration of one-year follow-up.MethodsOne hundred non-smoking women, undergoing laparoscopic Roux-en-Y gastric bypass, were included in the study. Blood assay for sex-hormone binding globulin (SHBG), testosterone, estrogen, progesterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) was analyzed. Participants completed the Female Sexual Function Index (FSFI), Women’s Health Questionnaire (WHQ) and Psychological General Well-being Inventory (PGWB) parallel to lab testing.ResultsAt one-year follow-up, several significant results were found concerning hormones and questionnaires. Testosterone decreased and SHBG increased, N = 68/100. Desire, arousal, orgasm, satisfaction and total score domains for the FSFI increased after one year, N = 53/100. WHQ domains concerning depressed mood, somatic symptoms, memory, anxiety, sexual behavior and attractiveness improved after one year, N = 47/100. All domains in the PGWB (N = 52), including anxiety, depressed mood, positive well-being, self-control, general health, vitality and total score improved at follow-up. Spearman’s Rho coefficient analysis found correlation between testosterone/WHQ-sexual problems (0.3), SHBG/WHQ-general health (0.3) and SHBG/FSFI-arousal (−0.3).ConclusionsBariatric surgery normalizes levels of sex-hormones in women, and results in improved sexual function, health-related quality of life and psychological well-being.

Obesity and Effects of Bariatric Surgery - with a Certain Focus on Women's Health

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Severe obesity influences sex hormone levels in women, which may result in subfertility, menstrual disturbances, anovulation and hyperandrogenism as well as increased risk for complications during pregnancy and birthing. Bariatric surgery leads to long-term weight loss and resolution of several comorbidities including hormone imbalance. However, the impact of altered sex hormones in women with obesity is insufficiently understood. Little is known concerning potential influences of changed sex hormone levels on women's function and quality of life following bariatric surgery and subsequent weight loss. This thesis aims to understand sex hormone balance in women with severe obesity and after bariatric surgery and to explore women’s experiences of changes in life after bariatric surgery and weight loss. Study I included 100 women and utilized blood assay to investigate changes in serum sex- hormone levels and questionnaires concerning sexual function and health-related quality of life (HRQoL) in women with severe obesity before and one year after bariatric surgery. Findings from Study I indicated that testosterone and sex hormone binding globulin normalized, and questionnaires showed improvements in several domains of sexual function, psychological well-being and general health in women one year after surgery. Study II used a qualitative method, specifically thematic analysis, to explore women's pre- and postoperative experiences, indicating that increased fertility and achieved motherhood were motivating factors to undergo bariatric surgery. Fourteen women were interviewed, and the themes of “Experiencing Motherhood and Femininity” and “Achieving a Normal Life” emerged from the data. Study III applied the qualitative method with Gadamer’s hermeneutic analysis to understand the lived experiences of premenopausal women with obesity before and after having undergone bariatric surgery. A focus was on influences of altered sex hormones and potential restoration of levels after surgery. Ten women were included, and analysis of the horizons created the fusions of “Recognition of Unhealthy Body Weight”, “Dealing with Other People’s Opinions and Society’s Norms”, “Life has Changed in a Positive Way” and “Accepting Inner Self and Bodily Changes”. Finally, to elaborate on previous studies' findings and better understand the current knowledge base, a systematic review and interpretative meta-synthesis of published literature involving qualitative methods concerning women’s experiences of womanliness related to changes after undergoing bariatric surgery was conducted in study IV. Ten relevant studies were included, and a meta-synthesis, according to Gadamer’s hermeneutics, created the fusions of “Womanliness,” “A Healthy and Functioning Body,” and “Mind and Body Connection.” This thesis provides a clearer understanding of the experiences of living with obesity that motivate premenopausal women to seek bariatric surgery. The importance of postoperative benefits such as restored function, health and womanliness are illustrated as well as clarifying difficulties involving adaptations to life after surgery. These findings may inform potential bariatric surgery candidates and healthcare professionals of the experiences of women living with obesity, as well as expectations, postoperative experiences and challenges. These findings promote patient-centred guidance prior to surgery and during postoperative follow-up.
