the burden of non - communicable disease in the developing countries is increasing and leading to high mortality rates . nowadays , type 2 diabetes ( t2 dm ) is pandemic and there are no signs of reduction in incidence rates . diabetes is one of the most important risk factors for cardiovascular diseases and is the most prevalent cause of mortality in diabetic patients . metabolic syndrome is highly prevalent in type 2 diabetic patients and is a strong risk factor for cardiovascular diseases in such patients . it is estimated that 16% of people above 20 years of age globally have metabolic syndrome . in iran , this syndrome is dramatically prevalent and close to 34% of people above 20 years old have metabolic syndrome , according to the adult treatment panel ( atpiii ) . differences in genetics , diet , physical activity , age and gender in different societies can affect the prevalence of this syndrome . there is no globally accepted definition for the diagnosis of this syndrome and most studies use the atpiii criteria for defining metabolic syndrome . in 2005 , the international diabetes federation ( idf ) has suggested a definition for the diagnosis of people with metabolic syndrome , which is applicable to different ethnic groups . in the idf criteria , central obesity is a prerequisite and central obesity assessment by waist circumference for different genders and ethnic groups according to idf is necessary . , the appropriate cutoff point for the diagnosis of metabolic syndrome in men and women in kerman has been determined . currently , metabolic syndrome has become an important health problem and there is a need for investigation in this field . considering the fact that diabetic patients with metabolic syndrome also have cardiovascular risk factors , the diagnosis of metabolic syndrome in such patients is very important , and leads to a better disease control and prevention of cardiovascular complications . the present study was performed to determine the prevalence of metabolic syndrome and its related factors in type 2 diabetic patients of kerman , iran . the data used in this study was part of the coronary artery disease risk factors ( kercadr ) study in kerman . in kercadr , 5,900 people were recruited from which 950 people were diagnosed with diabetes and entered into our study in 2013 . the variables evaluated in this study were age , gender , job , education , bmi , total cholesterol , hdl cholesterol , ldl cholesterol , fasting blood sugar ( fbs ) , systolic blood pressure , diastolic blood pressure , waist circumference , triglycerides , smoking , physical activity , the duration of diabetes , history of cardiovascular diseases , and the ratio of waist circumference to hip circumference . data was analyzed by chi - square , t - test , and logistic regression using spss ( revision 20 ) software . the prevalence of metabolic syndrome in people with diabetes was determined according to the below criteria . the atpiii criteria that include three or more of the following items : 
 central obesity : waist circumference more than 102 centimeters in men and more than 88 cm in womentriglycerides 150 mg / dl or using drugs for hyper triglyceridemiacholesterol hdl < 40 mg / dl in men and less than 50 mgr / dl in women or under treatment for low hdl cholesterolhypertension systolic blood pressure more than 130 mmhg or diastolic blood pressure 85 mmhg or being under treatment for hypertensionfbs 100 mg / dl or being under treatment for diabetes or a diagnosis of type 2 diabetes.according to the idf 2005 criteria , central obesity ( waist circumference 94 cm in men and 80 cm in women ) and two or more of these criteria should be present : triglyceride 150 mg / dl or under treatment for hyper triglyceridemiacholesterol hdl < 40 mg / dl in men and less than 50 mgr / dl in women or under treatment for low hdl cholesterol levelshypertension systolic blood pressure more than 130 mmhg or diastolic blood pressure 85 mmhg or being under treatment for hypertensionfbs 100 mg / dl or being under treatment for diabetes or a diagnosis of type 2 diabetes . 
  central obesity : waist circumference more than 102 centimeters in men and more than 88 cm in women triglycerides 150 mg / dl or using drugs for hyper triglyceridemia cholesterol hdl < 40 mg / dl in men and less than 50 mgr / dl in women or under treatment for low hdl cholesterol hypertension systolic blood pressure more than 130 mmhg or diastolic blood pressure 85 mmhg or being under treatment for hypertension fbs 100 mg / dl or being under treatment for diabetes or a diagnosis of type 2 diabetes . according to the idf 2005 criteria , central obesity ( waist circumference 94 cm in men and 80 cm in women ) and two or more of these criteria should be present : triglyceride 150 mg / dl or under treatment for hyper triglyceridemia cholesterol hdl < 40 mg / dl in men and less than 50 mgr / dl in women or under treatment for low hdl cholesterol levels hypertension systolic blood pressure more than 130 mmhg or diastolic blood pressure 85 mmhg or being under treatment for hypertension fbs 100 mg / dl or being under treatment for diabetes or a diagnosis of type 2 diabetes . study is the presence of central obesity ( waist circumference 86 cm in men and 83 cm in women ) plus two or more of these criteria : 
 triglyceride 150 mg / dl or under treatment for hyper triglyceridemiacholesterol hdl < 40 mg / dl in men and less than 50 mgr / dl in women or under treatment for low hdl cholesterol levelshypertension systolic blood pressure more than 130 mmhg or diastolic blood pressure 85 mmhg or being under treatment for hypertensionfbs 100 mg / dl or being under treatment for diabetes or a diagnosis of type 2 diabetes . triglyceride 150 mg / dl or under treatment for hyper triglyceridemia cholesterol hdl < 40 mg / dl in men and less than 50 mgr / dl in women or under treatment for low hdl cholesterol levels hypertension systolic blood pressure more than 130 mmhg or diastolic blood pressure 85 mmhg or being under treatment for hypertension fbs 100 mg / dl or being under treatment for diabetes or a diagnosis of type 2 diabetes . the present study was carried out on 950 patients with diabetes type 2 in which 392 ( 41.3% ) were male and 558 ( 58.7% ) were female . the mean age of the patients was 56.011.6 ( females 55.111.1 and males 57.212.2 ) . the prevalence of metabolic syndrome according to atpiii was 73.4% ( men 64.8% and women 79.4% ) . according to the idf criteria , it was 64.9% ( men 46.7% and women 77.8% ) and according to the new criteria , it was 70.4% ( men 69% and women 71.3% ) . figure 1 compares the prevalence of metabolic syndrome according to the three criteria . shows the prevalence of metabolic syndrome according to the three criteria among type 2 diabetics in different age groups . based on the result of the three criteria , among the females low hdl , high bmi , weight , blood pressure , ldl , total cholesterol , and triglyceride were associated with increased metabolic syndrome prevalence . the compatibility score of the atpiii and idf according to the kappa statistic was 0.49 , for idf and the new kerman criteria was 0.66 , and for atpiii and the new kerman criteria was 0.50 . multivariate logistic regression adjusted for confounders , in people who had metabolic syndrome according to both idf and atpiii criteria , showed that gender , fasting blood sugar , triglycerides , hdl , waist circumference and systolic blood pressure were predictive factors for metabolic syndrome in the population . also in people who had metabolic syndrome according to the three criteria , the same variables were able to predict the incidence of metabolic syndrome . the adjusted or with 95% confidence intervals for factors predicting metabolic syndrome according to both atpiii and idf in the present study , the prevalence of metabolic syndrome in patients with diabetes was 64% to 73% . in studies carried out in ahvaz , the prevalence of metabolic syndrome in diabetic patients was 73.1% ( atpiii ) and 64.9% ( idf ) , in esfahan 65% ( atpiii ) , and in england 94% ( both atpiii & idf ) . in other studies , the prevalence of metabolic syndrome was estimated to be 62.3% and 56.8% ( idf and atpiii ) in india , and 71.1% and 60.4% ( idf and atpiii ) in sub - saharan africa . in the present study , according to the three criteria , the prevalence of metabolic syndrome was higher in women than men . in all other studies , the reason might be less activity , more weight and higher prevalence of dyslipidemia in women . the female gender , fasting blood sugar , triglyceride , cholesterol , hdl , waist circumference and systolic blood pressure were able to predict the prevalence of metabolic syndrome in people with diabetes . in the ahvaz study , the female gender , physical activity , microalbuminuria , serum triglyceride and cholesterol , and in the isfahan study , age , gender , fasting blood sugar , hypertension , bmi , serum triglyceride and serum cholesterol were the predictors of metabolic syndrome . the female gender , cholesterol , and triglyceride in all these studies were a predicting factor . the difference among other variables could be due to differences in data collection , sampling methods and using different criteria in diagnosing people with metabolic syndrome . among the limitations of the present study is that the population was from kerman province and the results may therefore not be generalisable to other populations . the present study shows that the prevalence of metabolic syndrome in people with type 2 diabetes is very high in kerman .
