Abstract

Purpose The prevalence of obesity and the number of bariatric surgeries are increasing in Saudi Arabia. Studies evaluating nutritional knowledge, especially in Middle Eastern countries, are limited. Therefore, this study was conducted to examine the general and postbariatric nutritional knowledge related to dietary recommendations among patients undergoing bariatric surgery. Patients and Methods In a cross-sectional study, 112 patients aged 18–65 years, of both genders, were recruited from the Surgical Clinics at King Abdul-Aziz University Hospital in Jeddah, Saudi Arabia. Patients' knowledge pertaining to general nutrition and consumption after bariatric surgery was assessed in relation to dietary recommendations, using a preoperative questionnaire. Results The mean general nutrition knowledge score was 42 of a maximum of 85 points (50%). Approximately 40% and 60% of patients were classified with a low and medium level of nutritional knowledge, respectively. Postbariatric nutritional knowledge among patients was very low (mean: 16/81 points). The level of education was correlated with patients' body mass index (p=0.045) and the general nutritional knowledge total score (p=0.05). Conclusion General and postbariatric nutritional knowledge among Saudi bariatric patients is currently insufficient. A multicenter study involving a larger sample size with different sociodemographic characteristics is warranted to confirm these findings. The purpose of such a study would be to determine the nutritional knowledge of patients undergoing bariatric surgery and inform the implementation of educational strategies.

Highlights

  • Obesity is a major public health concern in the Kingdom of Saudi Arabia, where one in three adults are obese and at least one in 10 adults have morbid obesity [1, 2]. is condition is a risk factor for a range of diseases that adversely impact the health of the Saudi population [3]

  • Noncompliance to dietary recommendations leads to rapid weight regain or failure to reach the appropriate weight after bariatric surgery [12]. erefore, it is essential to evaluate the general nutritional knowledge of bariatric patients regarding appropriate sources of nutrients, selection of daily food, and the dietdisease relationship to identify knowledge gaps related to dietary intake and habits that may have contributed to their obesity. is information will assist in planning appropriate educational intervention strategies that may improve knowledge and aid adherence to the dietary and lifestyle changes necessary for the successful long-term outcome of bariatric surgery [13, 14]

  • There are no previous studies conducted in Saudi Arabia investigating the nutritional knowledge of bariatric patients or that are similar in nature to be used as a reference. erefore, we performed the sample size calculation based on the King Abdul-Aziz University Hospital (KAUH) statistics regarding bariatric surgeries from 2018 using the online Epi Info sample size calculator (Division of Health Informatics & Surveillance, and Centre for Surveillance, Epidemiology & Laboratory Services) [15]. e KAUH statistics showed that approximately 190 patients underwent bariatric surgeries

General and Postbariatric Nutritional Knowledge among Patients Undergoing Bariatric Surgery. E prevalence of obesity and the number of bariatric surgeries are increasing in Saudi Arabia. Erefore, this study was conducted to examine the general and postbariatric nutritional knowledge related to dietary recommendations among patients undergoing bariatric surgery. Patients’ knowledge pertaining to general nutrition and consumption after bariatric surgery was assessed in relation to dietary recommendations, using a preoperative questionnaire. Postbariatric nutritional knowledge among patients was very low (mean: 16/81 points). E level of education was correlated with patients’ body mass index (p 0.045) and the general nutritional knowledge total score (p 0.05). General and postbariatric nutritional knowledge among Saudi bariatric patients is currently insufficient.
