Background and Objective: The metabolic syndrome is a cluster of metabolic disorders that are associated with elevated risk of cardiovascular diseases and type-II diabetes. This study investigated the prevalence of metabolic syndrome among adolescents population in Gorgan, Northern Iran - 2009.

Materials and Methods: A cross-sectional survey was conducted involving 450 adolescents 15-17 years, selected through 2 stage cluster randomized sampling from high schools. Anthropometric measurements, blood pressure, fasting blood glucose and lipid profile were assessed. Metabolic syndrome was defined according to NHANES III criteria. Data was analyzed by SPSS-16 software, Chi-Square and logestic regration.

Results: The overall metabolic syndrome prevalence was 3.3% (CI 95%:1.8–5.4). More than half of cases (54.6%) had at least 1 or 2 components. High triglyceride level was the most common disorder in both genders (boys 27.6%, girls 52.4%) and then low HDL cholesterol level (17.3%) and central obesity (7.6%) were common among boys and girls respectively. Where as abdominal obesity in boys (0.9%) and hypertension in girls (3.1%) were less common.

Conclusion: This study showed that the rate of metabolic syndrome is slightly lower but the obsity in adolescents is higher than other parts of country.

Background and Objective: Polycystic Ovarian Syndrome (PCOS) is considered as a metabolic disorder and it is one of the most common endocrine and heterogeneous disorders with complex pathogenesis among women in reproductive ages. This study was done to evaluate the accuracy of diagnosis of lipid accumulate product index (LAP), insulin resistance, waist circumference and waist to hip ratio in women with polycystic ovary syndrome.
Methods: In this case control study, antropometrics, biochemical parameters, LAP and insulin resistance in 43 women suffering from PCOS as case and 40 healthy women as control were measured. Body mass index (BMI), waist hip ratio (WHR) and waist circumference (WC) was determined for each subject. LAP was defined as [WC (cm)-58´TG (m mol/L)]. PCOS was diagnosed according to Roterdam standard .Insulin resistance was defined based on Homeostatic model assessment – insulin resistance (HOMA-IR).
Results: The mean age, BMI, WHR and LAP index, among PCOS women were 24.06±5.86, 26.61±4.34, 0.81±0.061 and 47.13±4.13, respectively. There was a direct and significant correlation between HOMA-IR index and BMI, WC and LAP in case group (P<0.05). Statistical analysis showed that the optimal cut-off value of LAP, BMI, WC and WHR were 46.93, 27.91, 93 and 0.81 respectively.
Conclusion: The WC, BMI and LAP indices are useful in screening the insulin resistance in patients with PCOS.
