Early detection and treatment of dyslipidemia can avoid risk for Accepted 7 September 2018 cardiovascular disorder in diabetic patients. This study was conducted to determine the prevalence of and pattern of dyslipidemia in diabetic patients. Keywords: Materials and methods: This cross sectional study was performed in several specialized diabetic hospital Bangladesh of Noakhali, a southern district of Bangladesh. All known cases of diabetes mellitus were evaluated for Cardiovascular diseases their lipid profile. A total number of 1008 patients were included in the study having 683 (67.8%) female Dyslipidemia Type 2 diabetes and 325 (32.2%) male subjects. Prevalence Results: The prevalence of dyslipidemia among the male subjects was 73% while among female subjects 71%. Among diabetic males the percentage of high serum Cholesterol, high serum TG (Triglyceride), low HDL (High density cholesterol) and high LDL (Low density cholesterol) was 35.69%, 44.31%, 50.15% and 72.92% respectively, whereas the female had the percentage at 35.29%, 40.85%, 49.49% and 70.57% respectively. Conclusion: Majority portion of the study subjects were dyslipidemic. The most prevalent pattern among both male and female was high level of LDL and low level of HDL. The prevalence of dyslipidemia in Bangladesh is significantly high, which indicates the urgency of lifestyle intervention strategies to pre- vent and manage this important health problem and risk factor. © 2018 Diabetes India.

The World Health Organization recently reported that dyslipidemia is signifi- Gradually increasing rapid socioeconomic development and cantly associated with more than half of global cases of ischemic related lifestyle changes has been causing an increase in the heart disease [16]. prevalence of dyslipidemia dramatically over the past decade in Dyslipidemia in the diabetic patients is a common phenomenon, Bangladesh and other South Asian countries [1e12] Studies from because insulin resistance or deficiency affects key enzymes and India and Bangladesh showed an increasing trend in the prevalence pathways in lipid metabolism and thus causing lipid abnormalities of dyslipidemia [11]. which are more prevalent in diabetes mellitus [17]. Particularly, the Dyslipidemia has been clearly determined as a major risk factor following processes are affected: apoprotein production, regulation for cardiovascular diseases that are the first cause of death in the of lipoprotein lipase, action of cholesteryl ester, transfer proteins developed and developing countries [13]. It has become one of the and hepatic and peripheral actions of insulin [18,19]. The presence leading cause of death in most developed countries as well as in of dyslipidemia (DLP) significantly increases cardiovascular risk among patient with diabetes [20]. Again, studies show that about 70e80% of diabetic patients will die of cardiovascular disease [21,22].

Therefore, the objective of this study was to gather current data general characteristics of the subjects according to age and gender on dyslipidemia and to find out the relation between serum lipid including: age, weight, height, BMI (Body Mass Index), region, profile and blood sugar depending on the hypothesis that early systolic and diastolic blood pressure, total cholesterol (TC), TG detection and treatment of lipid abnormalities can minimize the (Triglyceride), HDL (High density Lipoprotein), LDL (Low density risk for atherogenic cardiovascular disorder and cerebrovascular Lipoprotein) and plasma glucose.
