RESUMEN
As a result of the increasing global incidence of obesity and related diseases, this study aims to investigate the prevalence of obesity and its correlation with eating disorder (ED) screening among medical students to develop effective prevention strategies and provide better outcomes for these students. We conducted a quantitative analytical cross-sectional study at the College of Medicine at King Saud University between November 2023 and February 2024. A stratified random sampling technique was utilized, enrolling a net number of 415 participants. Participants were asked several questions, including demographic information, weight, height, and past medical history, and were given a validated screening tool for EDs. Participants' mean age was 21.4 ± 1.67 years, and 17.6% were considered obese. The prevalence of positive screening for EDs was 27.7%; it was more common in females (p = 0.013) and those who earned more than 1000 SAR per month (p = 0.011). Female students also exhibited almost twice the odds of having EDs than males (AOR = 1.957; 95% CI = 1.218-3.146; p = 0.006). Furthermore, non-obese students showed decreased odds of having EDs compared with obese students by at least 48% (AOR = 0.517; 95% CI = 0.287-0.929; p = 0.027). Our study revealed a concerning prevalence of ED symptoms and obesity among medical students, suggesting profound implications. Therefore, multicenter studies are needed to assess the generalizability of the results and apply the findings to targeted national campaigns and interventions tailored specifically to medical students.
RESUMEN
OBJECTIVES: To examine the colonoscopy referrals in an open-access system and determine the outcome and factors associated with appropriate referral. METHODS: A retrospective study of colonoscopy referrals used patients' medical records at King Khalid University Hospital, Riyadh, Saudi Arabia, during 2020-2022. Fisher's exact or Pearson's Chi-squared test were used for data analysis. RESULTS: Out of 365 patients, 95.1% were referred from family medicine clinics with a mean age of 56.2±15.7 years. Men account for 53.2% of patients. The most common symptoms were change in bowel habits (35.6%), abdominal pain (30.4%), and anemia (20.1%). A family history of colorectal cancer was positive in 12.1%, while a personal history was positive in 4.4%. Most referrals (86.0%) were appropriate based on the American Society for Gastrointestinal Endoscopy (ASGE) guidelines. However, approximately 89.1% of patients aged ≥45 years had neoplasia and 40.0% had inflammatory bowel disease (p=0.019). The rank of the physicians (p=0.558) or the gender of the patients (p=0.665) did not influence the appropriateness. The inappropriate referrals were lower in patients with neoplasia (1.6%) than in patients with other lesions (p=0.002). CONCLUSION: The colonoscopy referrals were appropriate. The incidence of neoplasia was higher among those aged ≥45. Low inappropriate referrals and a high neoplasia detection were found based on ASGE guidelines. Future research should involve prospective multicenter referrals from family physicians outside hospitals and investigate patients' hesitancy to proceed with colonoscopy and cost-effectiveness.
