Abstract
BACKGROUND: The study aims to determine adults' interest in weight loss methods and their predictors such as anthropometric parameters, physical activity, and sociodemographic factors. METHODS: A two-step procedure was adopted. First, anthropometric parameters of 1130 Polish adults were taken, and the body mass index (BMI), the waist-to-hip ratio (WHR), and the body fat (BF) percentage were calculated. Next, the participants completed a questionnaire consisting of questions about their interest in different weight loss methods, questions about physical activity, and metric questions. Interest in six arbitrarily selected weight loss methods was measured using a five-point Likert scale. For analysis ordinal logistic regression and omnibus likelihood ratio tests were used. RESULTS: The results proved different predictors of adults' interest in weight loss methods (measured on an ordinal scale). More interest in physical activity and diets as methods of weight loss is observed in underweight individuals (compared to normal body weight status), older, with better economic situation, and higher level of physical activity individuals. In the case of bariatric surgery and liposuction, more interest in this weight loss methods are observed in overweight (compared to normal body weight status), economically well-off participants, and in women (compared to men). More interest of liposuction as a weight loss method is observed in overweight. Interest in dietary supplements to support weight loss (DSSWL) is more in women (compared to men), higher WHR, better economic situation, higher level of education and older individuals. More interest in weight loss drugs is observed in women (compared to men) and economically well-off people. CONCLUSION: The key predictors of interest in weight loss methods are body weight status, gender, and economic situation. These vary in importance depending on the type of weight loss method. Healthcare providers should recommend various weight-management strategies, having regard for the level of interest in weight loss methods and their predictors.
