Medical or Common Knowledge? Knowledge of Medical Professionals on Obesity Diagnosis Criteria and Treatment

Abstract

Introduction: Proper diagnosis of obesity and effective treatment requires an interdisciplinary healthcare approach. Nevertheless, obesity remains under-identified and under-treated. Academic knowledge concerning obesity pathology, diagnosis, and treatment is advancing, it is not clear whether this translates into clinical practice. The goal of the study was to assess the knowledge of Healthcare Professionals (HCPs) on obesity, and particularly on the criteria for diagnosis as well as for conservative and surgical treatment. Methods: This cross-sectional study was conducted among active HCPs (N = 184), including physicians, nurses, physiotherapists, and paramedics who had contact with adult patients with obesity. The proprietary research survey, implemented in an online tool, was used to assess knowledge on the diagnosis and treatment of obesity and self-assessment of that knowledge. The analysis was limited to the following: body mass index (BMI) definition, BMI values, visceral obesity definition, bariatric surgery indications, choice of treatment method, role of diet and physical activity, knowledge of obesity pharmacotherapy, length of obesity pharmacotherapy, financing of bariatric procedures, and goals of bariatric treatment. The correct answers were determined according to the Polish guidelines. Results: Half of the respondents (52.2%) were doctors, 20.7% were nurses, 19.0% were physiotherapists, and 8.2% were other medical professionals. Among questions related to knowledge on obesity, 67.1% of respondents provided correct answers, with respondents answering questions concerning obesity diagnosis correctly more frequently (70.1%) than those concerning methods of treatment (64.6%). The largest number of correct answers were related to the definition of BMI and normal BMI values. The smallest number of correct answers pertained to the diagnostic criteria for visceral obesity and pharmacological treatment of obesity. There were no statistically significant impact of a responder's knowledge levels on the obesity of different HCPs. Workplace and participation in training sessions were found to have the largest impact on the level of knowledge on obesity. HCPs own assessment of their knowledge on obesity was negatively correlated with their actual level of knowledge. Conclusion: The prevalence of overweight and obesity implies that essentially every HCP has daily contact with patients with excessive body weight. Our research showed that 32.9% of HCPs did not have sufficient knowledge about how to diagnose and treat obesity.

Is Obesity a Cause for Shame? Weight Bias and Stigma among Physicians, Dietitians, and Other Healthcare Professionals in Poland—A Cross-Sectional Study

“…To the best of our knowledge, this study is one of the two studies conducted in Poland that compare knowledge on obesity among different healthcare professionals. The earlier study, published in 2023 [37], had a smaller group of 184 respondents and substantially differed in the composition of the study group, including 52.2% of physicians, 20.7% of nurses, and 19.0% of physiotherapists compared to 58.7% of physicians, 17.0% of dietitians, and 24.3% of other healthcare professionals (including nurses, physiotherapists, pharmacists, dentists, and paramedics). Interestingly, no statistically significant differences in knowledge were observed among representatives of different medical professions in that study, in contrast to our research, where several such correlations were found.…”

Weight stigma and fat phobia in Poland – attitudes towards people living with obesity and the level of knowledge about obesity among the social media internet respondents and medical professionals

“…Two Polish publications from 2021 and 2023 also addressed attitudes towards the discrimination of patients with obesity ( 23 ) and the level of knowledge about obesity among medical professionals ( 24 ). They were based on a custom questionnaire and in-volved 184 medical professionals.…”

“…The second study assessed the knowledge about obesity. Percentage of 67.1 of respondents provided correct answers, with better accuracy in regard to obesity diagnosis (70.1%) than treatment methods (64.6%) ( 24 ). However, neither of these studies utilised FPS or any other standardised tool, nor included direct questions evaluating stigmatisation reported by respondents.…”
