Levels of Physical Activity, Enjoyment, Self-Efficacy for Exercise, and Social Support Before and After Metabolic and Bariatric Surgery: a Longitudinal Prospective Observational Study.

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.

A lifelong struggle for a lighter tomorrow: A qualitative study on experiences of obesity in primary healthcare patients.

AIM: To describe experiences of living with obesity before the start of a group-based lifestyle intervention. BACKGROUND: Obesity is a chronic disease that affects a person's physical and psychological health. Increased knowledge of experiences of living with obesity is required. DESIGN: A qualitative study with a descriptive design. METHODS: Semi-structured individual interviews with 17 participants living with obesity (Body Mass Index 32-49) were conducted between October and November 2019. The interviews were analysed using qualitative content analysis. The COREQ checklist was followed. RESULTS: The analysis resulted in one main theme: Struggling for a lighter tomorrow and three subthemes: Suffering, Resilience and Need for support in making changes. For the majority of the participants, living with obesity was a lifelong struggle involving suffering on different levels. Yet despite this, the participants had not given up and hoped for a better life. They showed a degree of resilience and motivation, and a perceived ability to achieve lifestyle changes. However, there was a pronounced need for support to help them achieve this. CONCLUSION: Living with obesity is complex and carries a risk of medical complications as well as psychosocial suffering. Healthy lifestyle habits to achieve better health and to lose weight should be encouraged, taking patient resources into account. Patients also need help in handling weight stigmatisation, and both healthcare professionals and society must engage with this. RELEVANCE TO CLINICAL PRACTICE: Obesity is a chronic disease, and patients need ongoing support. Therefore, care for patients with obesity in primary health care must be further developed. Patient resources and strengths have to be acknowledged and encouraged in the process of helping them adopt healthy lifestyle habits. The findings of this study can contribute to ending weight stigmatisation by increasing the knowledge of living with obesity.
