Dyslipidemia Prevalence in Iranian Adult Men: The Impact of Population-Based Screening on the Detection of Undiagnosed Patients

PURPOSE: Dyslipidemia has been established as one of the most important modifiable risk factors for cardiovascular disease. Due to the higher prevalence of dyslipidemia in males, this study aimed to estimate the prevalence of dyslipidemia in Iranian urban men. MATERIALS AND METHODS: A screening program was conducted in 845 Iranian men 25 years of age and older in 2014. A health interview survey was conducted to evaluate the prevalence of self-reported dyslipidemia and to collect demographic data, as well as serum lipid profile screening by a reference laboratory. Lipoprotein levels was categorized based on the Adult Treatment Panel III criteria and the data were analyzed using the chi-square test and analysis of variance. RESULTS: The overall prevalence of dyslipidemia was 51.8%, and the prevalence of various forms of dyslipidemia was as follows: hypercholesterolemia (> or =240 mg/dL), 11.4%; hyper-low-density lipoprotein cholesterol (> or =160 mg/dL), 9.6%; hypertriglyceridemia (> or =200 mg/dL), 25%; and hypo-high-density lipoprotein (HDL) cholesterol (<40 mg/dL), 34.3%. With the exception of hypo-HDL, all forms of dyslipidemia were significantly less common in men over 65 years of age (p<0.05). CONCLUSIONS: The prevalence of hypo-HDL and hypertriglyceridemia was higher than expected in Iranian adult men, with half of men 25 years of age and older affected by at least one form of dyslipidemia. A large gap in primary and secondary care was observed, because nearly 80% of patients with dyslipidemia were unaware of their status. Urgent preventive programs and lifestyle changes are necessary to reduce the prevalence of cardiovascular risk factors.

survey of the students' knowledge about hepatitis in Shiraz university of medical sciences

Because of the importance of hepatitis and the prevalence of contamination with hepatitis virus, a survey of the students' knowledge about viral hepatitis was conducted in Shiraz University of Medical Sciences. This is a descriptive study performed in cross-sectional method. Ten percent of the students enrolled in different courses were selected by stratified sampling method. A structured questionnaire was designed to obtain information about their knowledge of hepatitis. The mean scores were 41.3 +/- 20.2 and 61 +/- 34.5 of 100 regarding knowledge about hepatitis and prevention of the disease, respectively. Students had more information about hepatitis prevention than about other aspects of the disease such as mode of transmission and symptoms. There were statistically significant differences between the knowledge of hepatitis by age, semester and educational degree [P<0.001]. This study showed no significant association between knowledge of hepatitis and sex, job, parents' education and the place of residence [P>0.05]. This study showed that students' knowledge of hepatitis was very weak. Their knowledge with respect to the prevention of the disease was higher than other aspects
