Cardiovascular disease (CVD) is a broad term that includes diseases that affect the heart and blood vessels, including coronary heart disease, heart failure, high blood pressure, and stroke. CVD is the leading cause of death in the United States, resulting in 700,000 deaths each year. Preliminary research has shown that increased consumption of fish, specifically the omega-3 fatty acids found in fish oil, has beneficial effects in people with CVD. Fish oil may also have positive effects on the psychological health and well-being of people with psychiatric disorders. However, more research is needed to confirm the positive physical and psychological effects of fish oil in healthy adults. The purpose of this study is to evaluate the effectiveness of fish oil at reducing CVD risk markers, symptoms of depression and antagonistic disposition, and levels of impulsivity and aggression. The study will also examine whether genetic variations influence the effects of fish oil on markers of inflammation, a characteristic of CVD.
This study will enroll healthy adults who habitually consume low quantities of long-chain omega-3 fatty acids. Participants will be randomly assigned to receive either fish oil supplements or placebo on a daily basis for 4 months. Study visits will occur at baseline and Months 2 and 4. At the baseline and Month 4 visits, participants will undergo blood collection; heart rate measurements; and interviews, psychological tests, and questionnaires to assess mood, disposition, impulsivity, and aggression. Additionally, medication adherence will be measured at the Months 2 and 4 study visits and through phone calls from study staff at Week 2 and Month 3.
