Omega-3 Fatty Acid Dietary Intervention (O3DI)

Not Applicable

Completed

• Conditions: Hypertriglyceridemia
• Interventions: Other: Control group; Other: Diet intervention

• Registration Number: NCT05025943
• Lead Sponsor: Nemours Children's Clinic

Brief Summary

Elevated cholesterol, including triglyceride levels, can lead to the development of cardiovascular disease in adulthood. A diet that is rich in omega-3 fatty acids (O3FA) can improve triglyceride levels in a way that is safe and does not require medication.

This is a single-center, prospective, unblinded, randomized-controlled dietary intervention study to assess the impact of an omega-3 fatty acid diet compared to a standard lifestyle intervention on serum triglyceride in patients with hypertriglyceridemia. The study consists of an 8-week dietary treatment period followed by an 8-week observation period.

Arm && Interventions

Group	Intervention	Description
Standard lifestyle intervention	Control group	American Heart Association Target Diet/Standard Lifestyle Intervention (SLI)
Standard lifestyle intervention + omega-3 fatty acid enriched diet	Diet intervention	American Heart Association Target Diet/Standard Lifestyle Intervention (SLI) + omega-3 fatty acid enriched foods

Primary Outcome Measures

Name	Time	Method
change in serum triglyceride level after an 8-week diet intervention compared to baseline	8 weeks	The study will test whether omega-3 fatty acid enriched diet is associated with a 20% or greater reduction in serum triglyceride levels.

Secondary Outcome Measures

Name	Time	Method
change red blood cell omega-3 fatty acid content / index after an 8-week diet intervention compared to baseline	8 weeks	Total levels of omega-3 fatty acids in red blood cell membrane phospholipids are measured. Percentages are reported as an index. The study will identify the index/total omega-3 fatty acid in red blood cells following initiation of an omega-3 fatty acid enriched diet.
