Item Restricted Dietary Avoidance Behaviors in a Clinical Sample of Adults with Inflammatory Bowel Disease(University of Texas at Austin, 2024) Almahmoud, Elham; Burgermaster, MarissaBackground: Inflammatory Bowel Disease (IBD) presents a significant clinical challenge due to its chronic nature and the unpredictable cycle of remission and relapse. Medical treatment often fails to fully control the disease leaving patients to endure debilitating gastrointestinal symptoms. Therefore, patients tend to seek dietary approaches to manage and prevent symptoms. Specifically, most of the patients prefer avoiding foods they perceive as problematic over following a special diet. However, there is a lack in understanding the rationale behind food avoidance and how food avoidance behaviors impact nutritional status and disease activity in IBD patients. Objectives: To qualitatively identify the factors influencing food avoidance in IBD patients and to examine the association between these avoidance behaviors and both malnutrition risk and inflammatory biomarkers. Methods: A secondary analysis was conducted using data from a multicenter cross- sectional study of adults diagnosed with IBD. Participants completed questionnaires assessing food avoidance and malnutrition risk, while inflammatory biomarkers were collected from health records. Qualitative thematic analysis was applied to identify the reasons behind food avoidance. Results: The study included 137 participants with a median age of 35 years. The thematic analysis revealed eight key themes for habitual food avoidance and nine themes for avoidance during flare-ups, with symptom management and advice from others and personal preference being prominent factors. Correlation analysis showed no significant association between food avoidance and the risk of malnutrition or inflammatory biomarkers. Conclusions: Among a clinical cohort of adult patients, food avoidance was influenced by a combination of past experiences, anticipatory fears, and external advice. These findings highlight the need for personalized dietary counseling to addresses individual differences and prevent unnecessary dietary avoidance.15 0Item Restricted Knowledge, perception, and experience with Ketogenic Diet for the treatment of overweight and obesity among adults: a systematic review(University Of Sheffield, 2024-07-30) Alghamdi, Ghaday; Akparibo, RobertBackground: during the past decades, the prevalence of obesity has significantly increased around the globe, leading to increased demand for dietary interventions for weight reduction. Among these, ketogenic diet (KD) has gained great attention among adults and has been proposed as a promising option to achieve significant weight loss in a short period of time. Aim: to evaluate and critically appraise the current observational data exploring knowledge, perception, and experience of individuals using KD for weight loss, including their adherence to the diet. Methods: relevant studies were identified through five electronic databases: Web of Science, Medline via Ovid, CINAHL, Scopus, and PsycInfo, which sufficiently covered all key disciplines for the review. Eligible studies included observational studies published from 2020 to 2024, in English language, and exploring adults’ knowledge, perception, and experience with KD to manage their weight. Quality of the included studies was assessed using the AXIS appraisal tool for cross-sectional studies (CSSs). A narrative synthesis was carried out to summaries and interpret the results. Results: five studies were included in the review. The quality of studies varied: three studies were of high quality, one was of moderate quality, and one was of low quality. All of the five studies assessed adults’ knowledge and perception of KD for weight management, and three explored their current/ previous experience with the diet. In general, the overall knowledge level of participants was “good” except for one study that reported inadequate level of knowledge. The majority of participants agreed that KD is a popular weight loss intervention but argued about how safe and easy it is to be followed in the long term and that it should always be followed under medical supervision. Participants’ experience with KD showed effective weight loss outcomes with slight variations in adherence duration. The minimum duration for following KD was less than a month, and the maximum duration was six months, leading to weight regain among some participants. Conclusions: the findings conclude that KD has been an effective weight loss strategy if followed under medical supervision. However, adherence level to the diet was low, which increased the chance of weight regain. Future research: robust studies are required to evaluate KD’s potential long-term health implications, as well as assess KD effectiveness for the treatment of overweight and obesity including its sustainability.23 0Item Restricted Knowledge, perception, and experience with Ketogenic Diet for the treatment of overweight and obesity among adults: a systematic review(University Of Sheffield, 2024-05-08) Alghamdi, Ghaday; Akparibo, RobertBackground: during the past decades, the prevalence of obesity has significantly increased around the globe, leading to increased demand for dietary interventions for weight reduction.

However, no previous research examines the effect of diet and weight-related RPs of COVID-19 on weight and diet, including high fat sugar and/or salt (HFSS) food consumption and fruit and vegetable (FV) consumption. This study examined these effects cross-sectionally at baseline and longitudinally at 6-months while accounting for sociodemographic, anthropometric, health and COVID-related factors. Design: A secondary data analysis of the longitudinal survey of HEalth BEhaviours during the COVID-19 (HEBECO) pandemic was conducted (N=1910 UK adults). Methods: Participants self-reported data on sociodemographic, anthropometrics, diet, health and COVID-related factors. Pandemic-related data from baseline (April- June,2020) and the 6-month follow-up (November-December,2020) were analysed. Results: Multiple regressions revealed higher diet and weight-related RPs were associated with higher baseline HFSS consumption (β=.11,p<.001) and weight (β=.31, p<.001). Similarly, higher RPs were associated with higher HFSS consumption (β=.07, p=.005) and weight (β=.34, p<.001) at 6-months. Although RP did not predict change in HFSS consumption from baseline to 6-months, RP was associated with an increase in weight from baseline to 6-months. Multivariate logistic regressions revealed no significant association between RPs and meeting FV recommendations at baseline or 6-months. Conclusion: Findings highlight the importance of considering the role of diet and weight-related RPs in developing public health strategies to influence healthy eating and weight during and beyond the pandemic. Future research can consider examining these relationships in other countries and using more objective measures to increase reliability.33 0
