Study summary

In this proposed study, the investigators will evaluate the effects of fish oil add-on in treatment of major depressive disorder(MDD).

Read the detailed description

Participants are randomly assigned to two groups (n=60): control (placebo, soybean) and fish oil (containing EPA 1440mg, DHA 960mg). The experimental groups will be compared to placebo to evaluate if it may benefit clinical symptoms, cognitive symptoms and metabolic markers in MDD patients. We also plan to investigate the changes in markers of inflammation at the same time.

Study arms

  • Experimental
    experimental group

    the experimental group will be given 4 fish oil capsules (1g/one capsule)twice daily after two meals at roughly the same time each day,lasting for the first 6 months.fish oil capsule will be provided by the Hunan Kangqi100 Biological Technology Co.Ltd.

    Dietary Supplement: fish oil capsule

  • Placebo comparator
    control group

    the control group will be given 4 soybean oil capsules ( placebo capsule,1g/one capsule) twice daily after two meals at roughly the same time each day,lasting for the first 6 months.placebo capsule will be provided by the Hunan Kangqi100 Biological Technology Co.Ltd.The placebo capsule's appearance and flavor are made the exactly the same as the fish oil capsules .

    Dietary Supplement: soybean oil capsule

Interventions

  • Dietary supplementfish oil capsule

    N-3 PUFAs is a kind of essential fatty acid,however the formation is too slow. Studies show that intakes of N-3 PUFAs is associated with MDD.It have to be got from food like deep-sea fishes. EPA and DHA are crucial for the body.Although studies have shown that reduced N-3 PUFAs were correlated with MDD, and patients with an elevated rate of N-6 PUFAs /N-3 PUFAs or a low level of DHA may be at higher odds for suicide. Trials on whether N-3 PUFAs is effective in the treatment of MDD is still controversial, which might be affected by several factors, such as dose, duration etc.. Now there is no large-scale randomized controlled clinical trial in determining the effects of N-3 PUFAs add-on in treatment of MDD.

What researchers measure

Primary outcomes

  1. Changes in Hamilton Depression Scale (HAMD) HAMD

    Subjects were evaluated for current depression with HAMD.

    Time frame: W0 W4 W12 W24 W48

Secondary outcomes

  1. Changes in Clinical Global Impression (CGI)

    Subjects were evaluated for current severity of disease with CGI.

    Time frame: W0 W4 W12 W24 W48

  2. Changes in Hamilton Anxiety Scale (HAMA)

    Subjects were evaluated for current anxiety with HAMA.

    Time frame: W0 W4 W12 W24 W48
