Fetma och övervikt är ett hot mot folkhälsan. Många med övervikt och fetma försöker gå ner i vikt, men få lyckas bibehålla viktminskningen. Studiens syfte var att ta reda på erfarenheter av betydelsefulla faktorer och strategier för en bestående viktminskning, samt motivation för bibehållandet av vikten. Enligt Self-determination theory (SDT) blir beteendeförändringar bestående om de är autonoma och om motivationen är intern. Åtta kvinnor som deltagit i Itrims viktminskningsprogram intervjuades. Resultatet visade att förändringar i kost, motion och förhållningssätt var för egen vinning och viktiga för en bibehållen vikt. Andra faktorer var kunskap, psykiskt och fysiskt välmående samt vilja. Bibehållandet av viktminskningen var ett självständigt arbete där kunskaper från programmet och från inre reflektion införlivades i livsstilen, vilket överrensstämmer med SDT.

Obesity is a chronic and growing disease defined by weighing 20% or more than the ideal, or having a body mass index (BMI) of 30 kg/m2 or more. While natural weight loss is available, many patients are choosing weight loss surgery (i.e., bariatric surgery) as an alternative to lose weight and reduce their risks for comorbidities such as diabetes, heart disease, and sleep apnea. Tools and resources for post-surgical support in the bariatric surgery community have been limited and, in the past, most tools and resources for weight loss have focused on non-surgical weight loss communities; as such, analysis methods for measuring success in this population have not been clearly developed and tested. This research proposes and evaluates analysis methods that may be used in such studies. These analysis methods are evaluated using data from the Weight and Exercise Lifestyle Support study at Baystate Medical Center in Springfield, MA. In this study, a group of participants (n = 6) approved for bariatric surgery were followed by the research team starting roughly one month before surgery through three months after surgery. Participants received pedometers and weight scales, and access to an online patient portal where they could review their physical activity levels, and receive support from others in the study and an exercise consultant. Data collected included pre- and post-study dietary and exercise self-efficacy levels, self-reported and objective physical activity measures, self-reported dietary adherence, device usage, and usability and satisfaction with the program. This research evaluates whether the proposed measures can help determine the presence and nature of the relationships between the aforementioned variables. If these measures prove to be useful, they can be used in future interventions that use technology to support post-surgical weight loss communities.

The analyses in this dissertation were designed to 1) extend the knowledge of characteristics associated with and predictive of energy intake plausibility (under or overreported energy intake), and 2) extend previous research in a sub-sample of this study population of baseline short-term weight loss predictors to evaluate within the full sample whether baseline psychosocial, behavioral and dietary predictors of weight loss varied by energy intake plausibility. Subjects were 155 overweight or obese perimenopausal women participating in a 4mo lifestyle weight loss program. Based on self-reported intake from 3-d dietary records, women were categorized as energy underreporters (n=71), accurate energy reporters (n=27), or energy overreporters (n=57), using the cut-off values for energy plausibility defined by Goldberg. All subjects completed a comprehensive behavioral and psychosocial battery assessing diet and weight history, life status, weight loss readiness, psychology, eating behavior, physical activity, and self-image. Results from logistic regression models showed that y of education, weight loss aspirations, exercise perceived competence, social support to exercise, and measures of body image were the best predictors of energy underreporting. Dietary carbohydrate and fat intake, health related quality of life, and profile of mood states (anger) were the best predictors of energy overreporting. Baseline predictors of successful weight loss did vary by energy plausibility group, with unique predictors for energy underreporters including fewer previous dieting attempts and exercise perceived obstacles, and energy overreporters including higher TEE, more negative mood status and higher perceived hunger. Overall, more successful weight loss was also associated with higher baseline fruit and vegetable intake. Validation of these findings will help lead to establish factors to account or adjust for bias from energy misreporting, reduce health or disease risk underestimation and improve understanding of nutrition, health and disease relationships. Further, identification of successful weight loss predictors unique to energy under- and overreporters will enhance weight loss profiling and tailoring of interventions to optimize success.
