Objectives. We determine the prevalence of the metabolic syndrome in an urban population of Zanjan, a province located to the west of Tehran. Methods. Randomly selected adults >20 years were studied using stratified sampling. Target study sample was 2941 (1396 males and 1545 females). Metabolic syndrome was diagnosed using Adult Treatment Panel-III (ATP-III) guidelines when any three of the following were present: central obesity, raised triglycerides ≥150 mg/dl, low high-density lipoprotein (HDL) cholesterol, blood pressure ≥ 130/ ≥ 85 mm Hg, and diabetes or fasting plasma glucose (FPG) ≥ 100 mg/dl. Results. Metabolic syndrome was present in 697 (23.7%) subjects (CI 95%:22%–25%, P = .001), prevalence was 23.1% in men and 24.4% in women (P : .4). The prevalence increased from 7.5% in the population younger than 30 y to 45.6% in ages more than 50 years. Low HDL was the most common metabolic abnormality in both sexes. Most of those with metabolic syndrome had three components of the syndrome (75.6%), 170 subjects (24.4%) had four and none had five components simultaneously. The prevalence of obesity (BMI ≥ 30 kg/m2), hypercholesterolemia (≥200 mg/dl) and high LDL cholesterol (≥130 mg/dl) was greater in the metabolic syndrome group than normal subjects (P = .00). Conclusions. There is a high prevalence of metabolic syndrome in this urban population of the northern west of Iran. Focus of cardiovascular prevention should be undertaken in this area.

The prevalence of dyslipidemia, especially low HDL cholesterol, in Iranian adults is very high. Urgent preventive programs and changes in lifestyle are needed in this area.

10.30699/jambs.30.139.177 Background & Objective: Screening and timely diagnosis of positive individuals is one of the important issues in controlling pandemic of Covid-19. Early and timely diagnosis of asymptomatic individuals, contact tracking, disconnection of Covid-19 transmission chain through early detection of patients and decreasing R0 were the main objectives of the current study. Materials & Methods: The Covid-19 outpatient sampling detection project started in Zanjan province on March 26, 2020 and samples were taken from people suspected of having Corona Virus and people in contact with these patients.Results: All 31,937 cases (48% male, 52% female) who had referred to Comprehensive Health Care Centers until May 16, 2020, were selected. A considerable percentage of incidences were observed in Zanjan and Khodabandeh cities. 20% of the examined samples had positive results. A substantial incidence was found in the age group of over 70 -year-old. Following implementation of the outpatient screening project, R0 fell below 1 in the province. Conclusion:Prior to the implementation of Covid-19 laboratorial outpatient screening project, the value of R0 was 1.4 in Zanjan province. However, this value fell below 1, after implementation of the laboratorial outpatient screening indicating that the principal way to effectively control Covid -19 is to detect positive cases and manage them.
