1.  The effects of omega-3 on blood pressure and the relationship between serum visfatin level and blood pressure in patients with type II diabetes 
ARYA Atherosclerosis  2012;8(1):27-31.
Hypertension is a condition normally detected in people with type II diabetes.It eventually leads to cardiovascular diseases in the patient. Visfatin is an adipocytokine which issecreted from adipose tissue and can affect the inflammatory reaction and also serum lipidlevels. Additionally, omega-3 inhibits the accumulation of fat and formation of insulinresistance. The current study tried to investigate the effects of omega-3 on blood pressurecompared to placebo and the relationship between serum visfatin levels and blood pressure.
A total number of 71 women with type II diabetes were randomly assigned to2 groups to receive either omega-3 capsules or placebo capsules. In the first step, aquestionnaire consisting age, height, weight, waist and hip circumferences, and systolic anddiastolic blood pressure was filled out for each subject. Blood samples were then collected forlaboratory tests. The next step was to conduct 8 weeks of intervention. All variables, except age,were measured again after the intervention. Hip circumference was considered as the maximumcircumference of the buttocks. Waist circumference was measured by placing a tape horizontallyacross the abdomen at the end of a normal exhalation. Laboratory tests included the assessmentof visfatin, glucose, and glycated hemoglobin (HbA1c) concentrations. Lipid profile, i.e. lowdensity lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), and cholesterol,was also assessed. Using SPSS18, data obtained from the study was analyzed by a variety ofappropriate statistical tests.
There was a significant change in mean differences of systolic and diastolic bloodpressure. Blood pressure showed a significant reduction in the omega-3 group compared to theplacebo group. However, no significant changes were observed in systolic and diastolic bloodpressure before and after the intervention (P > 0.05).
Based on the results of this study, a daily consumption of omega-3 is suggestedfor patients with type II diabetes.
