Occupational Outcomes of Obesity Surgery—Do the Employed Return to Work, and Do the Unemployed Find Work?

Improvement of Work Ability After Weight Loss Surgery: Results of a Longitudinal Study of Patients Suffering from Extreme Obesity Before and 4 Years After Bariatric Surgery

PURPOSE

Body mass index (BMI) is directly associated with employment status. Our longitudinal prospective study is aimed at ascertaining whether work ability index (WAI) 4 years after surgery remains improved, such as 1 year after surgery, or changes and whether socio-demographic or psycho-social factors influence changes in work ability.

MATERIALS AND METHODS

197 bariatric surgery candidates were recruited. Data on demographic and psycho-social characteristics were collected prior to surgery (t1) and at 6 (t2), 12 (t3), and 48 months (t4). Change effects over time in the WAI and BMI were investigated using a repeated-measures analysis of variance (ANOVA). A hierarchical multiple regression analysis was calculated to predict socio-demographic and psychosocial characteristics at t1 on WAI at t4.

RESULTS

Not only a significant increase in WAI was observed between t1 and t2 and between t3 and t4 but also a significant decrease between t2 and t4. BMI reduction was significant between t1 and t2 and t3 and t4, respectively. There was no significant interaction effect of BMI reduction 4 years after surgery on decreased work ability from t2 to t4. The hierarchical multiple regression analysis revealed an association of WAI scores at t1 on WAI scores at t4 only.

CONCLUSIONS

Work ability 4 years after surgery remained significantly improved compared to the values at t1-t3 assessment. Since work ability was the only predictor at t1, findings might indicate the use of psycho-social measures post bariatric surgery to increase work ability. There was no association between work ability and other socio-demographic or psycho-social factors.

Back to Work After Bariatric Surgery? A Belgian Population Study

INTRODUCTION

Aside from an impact on health, obesity is also associated with higher social and economic costs such as impaired productivity, increased work absenteeism, and higher rates of unemployment. The aim of this study was to assess the effect of bariatric surgery on employment status in a large nationwide database, using data from all patients that underwent bariatric surgery in Belgium.

METHODS

This is a retrospective analysis of all Belgian patients that underwent bariatric surgery between 2014 and 2015. The work status of these patients was examined yearly: 4 years before and 3 years after surgery. Increased employment after surgery was defined (1) as a reduction in days of unemployment and incapacity and (2) as the resumption of work among the unemployed.

RESULTS

In total, 16,276 patients were included. The number of working people rose from 49.7% before to 61.2% 3 years after bariatric surgery, i.e., an increase of 11.5% between pre- and post-surgery. The largest improvement in reduction in unemployment was found in individuals who were absent from work for more than 9 months, namely, a reduction from 13.4 to 7.2%. In the population of unemployed patients, 20.9% became employed after bariatric surgery.

CONCLUSION

We found an increase in employment rate and a decrease in work incapacity and unemployment after bariatric surgery. Higher rates of employment after bariatric surgery may also contribute to an increased cost-effectiveness of bariatric surgery. It would be interesting to research possible targeting strategies to increase the employment rate even more after bariatric surgery.

Advice of General Practitioner, of Surgeon, of Endocrinologist, and Self-determination: the Italian Road to Bariatric Surgery

PURPOSE

Bariatric surgery (BS) is considered the most efficient treatment for severe obesity. International guidelines recommend multidisciplinary approach to BS (general practitioners, endocrinologists, surgeons, psychologists, or psychiatrists), and access to BS should be the final part of a protocol of treatment of obesity. However, there are indications that general practitioners (GPs) are not fully aware of the possible benefits of BS, that specialty physicians are reluctant to refer their patients to surgeons, and that patients with obesity choose self-management of their own obesity, including internet-based choices. There are no data on the pathways chosen by physicians and patients to undergo BS in the real world in Italy.

METHODS

An exploratory exam was performed for 6 months in three pilot regions (Lombardy, Lazio, Campania) in twenty-three tertiary centers for the treatment of morbid obesity, to describe the real pathways to BS in Italy.

RESULTS

Charts of 2686 patients (788 men and 1895 women, 75.5% in the age range 30-59 years) were evaluated by physicians and surgeons of the participating centers. A chronic condition of obesity was evident for the majority of patients, as indicated by duration of obesity, by presence of several associated medical problems, and by frequency of previous dietary attempts to weight loss. The vast majority (75.8%) patients were self-presenting or referred by bariatric surgeons, 24.2% patients referred by GPs and other specialists. Self-presenting patients were younger, more educated, more professional, and more mobile than patients referred by other physicians. Patients above the age of 40 years or with a duration of obesity greater than 10 years had a higher prevalence of all associated medical problems.

CONCLUSIONS

The majority of patients referred to a tertiary center for the treatment of morbid obesity have a valid indication for BS. Most patients self-refer to the centers, with a minority referred by a GP or by specialists. Self-presenting patients are younger, more educated, more professional, and more mobile than patients referred by other physicians. Older patients and with a longer duration of obesity are probably representative of the conservative approach to BS, often regarded as the last resort in an endless story.

Trajectory Analysis and Predictors of the Percentage of Body Fat Among Chinese Sleeve Gastrectomy Patients

BACKGROUND

The weight loss in Chinese patients after sleeve gastrectomy is different, and the differences can be evaluated through the trajectories of the percentage of body fat (BF%). Patients' baseline psychosocial factors may be associated with these trajectories.

MATERIALS AND METHODS

We selected 267 patients who received sleeve gastrectomy for the first time. The BF% at baseline and 1, 3, 6, 12 months after surgery and baseline psychosocial variables were retrospectively collected. The trajectory model was established according to BF% based on the growth mixture model. The baseline psychosocial variables were compared among different trajectory classes.

RESULTS

Four types of trajectory classes were obtained. The differences in preoperative dietary self-efficacy, exercise self-efficacy, depression, social support, working status, alcohol consumption, and gender among the classes were statistically significant. The pairwise comparison of the above variables revealed that the differences of gender, dietary self-efficacy and exercise self-efficacy among classes were highly effective.

CONCLUSION

Female gender, low dietary self-efficacy and low exercise self-efficacy were predictors for poor BF% trajectory in sleeve gastrectomy patients. Health professionals can early identify patients who are most likely to lose weight in a not-ideal manner based on the above predictors.

Place Work on a Scale: What Do We Know About the Association Between Employment Status and Weight Loss Outcomes After Bariatric Surgery?

Despite the initial successful weight loss after bariatric surgery, a significant amount of patients experience weight loss failure and weight regain. Several factors are known to contribute to this, though the impact of employment status is unknown. The objective of this systematic review was to examine the impact of employment status on post-surgical weight loss outcomes. Eight studies were included with a follow-up ranging between 2 and 10 years. Employed patients seemed to present more weight loss (9.0-11.0% EWL, 1.3-1.6% BMI loss) compared to unemployed patients, but none of these numbers were statistically significant. Moreover, there were contrasting findings in terms of weight regain. This review may highlight the importance of working status after bariatric surgery and warrants further investigation on this topic.

Development and Validation of New BODY-Q Scales Measuring Expectations, Eating Behavior, Distress, Symptoms, and Work Life in 4004 Adults From 4 Countries

PURPOSE

The BODY-Q is a rigorously developed patient-reported outcome measure (PROM) for patients seeking treatment for obesity and body contouring surgery. A limitation of the uptake of the BODY-Q in weight management treatments is the absence of scales designed to measure eating-specific concerns. We aimed to develop and validate 5 new BODY-Q scales measuring weight loss expectations, eating behaviors, distress, symptoms, and work life.

MATERIAL AND METHODS

In phase 1 (qualitative), patient and expert input was used to develop and refine the new BODY-Q scales. In phase 2 (quantitative), the scales were field-tested in bariatric and weight management clinics in the United States (US), The Netherlands, and Denmark between June 2019 and January 2020. Data were also collected in the US and Canada in September 2019 through a crowdworking platform. Rasch measurement theory (RMT) analysis was used for item reduction and to examine reliability and validity.

RESULTS

The new BODY-Q scales were refined through qualitative input from 17 patients and 20 experts (phase 1) and field-tested in 4004 participants (phase 2). All items showed ordered thresholds and good fit to the Rasch model. The RMT analysis provided evidence of reliability, with PSI values ≥0.72, Cronbach alpha values ≥0.83, and test-retest values ≥0.79. Better scores on 4 scales (exception expectations scale) correlated with lower BMI, with the strongest correlation between the eating-related distress scale scores and BMI (r= -0.249, P < 0.001).

CONCLUSION

The new BODY-Q scales can be used in research and clinical practice to assess weight loss treatments from the patient perspective.
