2.2. Study design
At the beginning of the study, all participants were matched
based on sex, number and type of hypoglycaemic medications, BMI
and age. Then, patients were randomly allocated into two groups to
receive either 1000 mg/day omega-3 fatty acid from flaxseed oil or
placebo for 12 weeks. Omega-3 fatty acid supplements and
placebos were manufactured by Barij Pharmaceutical Company
(Kashan, Iran). Randomization was done using a random number table by one of the investigators who had no clinical involvement in
the study. Patients were requested not to alter their ordinary
physical activity, and not to consume any nutritional supplements
that might influence their nutritional status during the 12-week
trial. Compliance to the intake of omega-3 fatty acid supplements
and placebos was evaluated through requesting participants to
return the medication containers and receiving short messages by
patients. All patients completed 3-days food records at study
baseline, end-of-trial and throughout the trial (week 3, 6 and 9 of
the intervention). Macro- and micro-nutrient intake was analyzed
by nutritionist IV software (First Databank, San Bruno, CA).
