BackgroundNowadays, Cardiovascular Diseases (CVDs) represents an escalating worldwide public health problem. Providing consistent data on the magnitude and risk factors of CVDs among young population will help in controlling the risks and avoiding their consequences.ObjectiveThe objective was to estimate the prevalence of risk factors of Coronary Heart Disease (CHD) among medical students during their clinical clerkship (4th - 6th years).MethodsA cross-sectional study was done during the educational year 2012–2013 at King Abdulaziz University (KAU), Jeddah. Ethical standards were followed and a multistage stratified random sample method was used for selection of 214 medical students. Data was collected through an interviewing questionnaire, measurements and laboratory investigations. Both descriptive and analytical statistics were done by SPSS version 21. CHD risk percent in thirty years was calculated using Framingham algorithm for each student, then the risk among all students was determined.ResultsThe commonest risk factors of CHDs were daily intake of high fat diet (73.4%), physical inactivity (57.9%), overweight/or obesity (31.2%) and daily consumption of fast food (13.1%). Hyper-cholesterolemia (17.2%) and hypertension (9.3%) were also prevalent risk factors. Smoking prevalence was low (2.8%). Males had significantly higher mean scores for most of CHD risk factors compared to females (p < 0.05). Systolic Blood pressure was higher among males (119.47 ± 11.17) compared to females (112.26 ± 9.06). A highly statistical significant difference was present (Students’t test = 4.74, p < 0.001). Framingham Risk Score revealed that CHD risk percent in thirty-years among all students was 10.7%, 2.3% and 0.5% for mild, moderate and severe risk, respectively.ConclusionAn alarmingly high prevalence of CHD risk factors was prevailed among medical students, especially among males. However, a low prevalence of smoking may indicate the success of “Smoke-free Campus” program. Screening risk factors of CHD among medical students and implementation of intervention programs are recommended. Programs to raise awareness about CHD risk factors, encourage young adult students to adopt a healthy dietary behavior and promote physical exercise should be initiated.
Background and study aim: Autoimmune hepatitis (AIH) is a chronic liver disease that can lead to progressive liver damage. The prevalence of AIH among the general population and among chronic liver disease (CLD) patients is variable worldwide. Currently, no published data on the prevalence of AIH among Saudi or among liver disease patients from the region. In this study, we aimed to assess the prevalence of AIH among CLD patients who were referred for transient elastography (FibroScan) in Saudi Arabia. Patients and methods: A retrospective study was conducted among CLD patients who had a transient elastography (FibroScan) during the 3-year study period. We obtained demographic data and test results for serum alanine aminotransferase (ALT), bilirubin, hemoglobin (Hgb), platelets, and international normalized ratio (INR) from all patients. We compared the results of the AIH patients to those of the non-AIH patients with CLD. In addition, for AIH patients, we measured serum immunoglobulin G (IgG), antinuclear antibody (ANA), smooth muscle antibody (SMA) and ALT at 2 -6 weeks and at 3 -4 months. Results: We included 494 patients, who were predominantly female (271 (60%)) and Saudi (299 (60.5%)). Thirty patients (6.1%) had AIH, which represented the 4 th most common liver disease. Compared to non-AIH patients, AIH patients were younger (mean ages 49.9 years, SD 14.22 years, and 40.4 years, SD 13.94 years, respectively, P = 0.001). Patients with AIH had significantly lower Hgb and platelets (P = 0.008 for both) and higher ALT, bilirubin and INR (P = 0.05, 0.047 and 0.019, respectively). More than 50% of the AIH patients had cirrhosis. Older age was not associated with advanced disease stage among the AIH patients (P < 0.001). AIH represents the 4 th most common cause of CLD in patients referred for transient elastography in Saudi Arabia. AIH tends to be severe in patients at a young age, with a marked biochemical response to steroids and azathioprine treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
