Effect of Vitamin D and/or Marine n-3 Fatty Acid Supplementation on Changes in Migraine Frequency and Severity.

ABSTRACT:

Background

There is interest in whether supplements, including vitamin D and marine omega-3 (n-3) fatty acids, may be effective migraine prophylaxis. However, few studies have evaluated whether vitamin D or n-3 fatty acid supplementation may reduce migraine frequency or severity.

Methods

Participants in the VITamin D and OmegA-3 TriaL (VITAL) were assigned to vitamin D₃ (2000 IU/d) or marine n-3 fatty acid (1 g/d) supplementation in a 2-by-2 factorial design. Lifetime history of migraine was assessed a median of 4.6 years after the start of the trial. Individuals were asked to self-report changes in migraine frequency (no change, more frequent, or less frequent) and severity (no change, more severe, less severe) in the past 5 years. We used χ² tests to compare proportions of individuals reporting changes in migraine frequency and severity between active and placebo groups.

Results

Among the 25,871 participants in VITAL, 1032 participants had a history of probable migraine and provided information on changes in migraine frequency and severity. The percentage of individuals reporting decreases in migraine frequency did not differ between active (69.0%) and placebo vitamin D (68.4%) (P value = 0.54) or between active (67.8%) and placebo n-3 fatty acid (69.6%) (P value = 0.82). Similarly, the percentage of individuals reporting decreases in migraine severity did not differ between active (64.1%) and placebo vitamin D (65.0%) (P value = 0.86) or between active (64.5%) and placebo n-3 fatty acid (64.5%) (P value = 0.96).

Conclusions

Neither vitamin D nor marine n-3 fatty acid supplementation, compared to placebo, affected migraine frequency or severity among middle-aged or older adults.

Project description:ImportanceAtrial fibrillation (AF) is the most common heart rhythm disturbance, continues to increase in incidence, and results in significant morbidity and mortality. The marine omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and vitamin D have been reported to have both benefits and risks with respect to incident AF, but large-scale, long-term randomized trial data are lacking.ObjectiveTo test the effects of long-term administration of marine omega-3 fatty acids and vitamin D on incident AF.Design, setting, and participantsAn ancillary study of a 2 × 2 factorial randomized clinical trial involving 25 119 women and men aged 50 years or older without prior cardiovascular disease, cancer, or AF. Participants were recruited directly by mail between November 2011 and March 2014 from all 50 US states and were followed up until December 31, 2017.InterventionsParticipants were randomized to receive EPA-DHA (460 mg/d of EPA and 380 mg/d of DHA) and vitamin D3 (2000 IU/d) (n = 6272 analyzed); EPA-DHA and placebo (n = 6270 analyzed); vitamin D3 and placebo (n = 6281 analyzed); or 2 placebos (n = 6296 analyzed).Main outcomes and measuresThe primary outcome was incident AF confirmed by medical record review.ResultsAmong the 25 119 participants who were randomized and included in the analysis (mean age, 66.7 years; 50.8% women), 24 127 (96.1%) completed the trial. Over a median 5.3 years of treatment and follow-up, the primary end point of incident AF occurred in 900 participants (3.6% of study population). For the EPA-DHA vs placebo comparison, incident AF events occurred in 469 (3.7%) vs 431 (3.4%) participants, respectively (hazard ratio, 1.09; 95% CI, 0.96-1.24; P = .19). For the vitamin D3 vs placebo comparison, incident AF events occurred in 469 (3.7%) vs 431 (3.4%) participants, respectively (hazard ratio, 1.09; 95% CI, 0.96-1.25; P = .19). There was no evidence for interaction between the 2 study agents (P = .39).Conclusions and relevanceAmong adults aged 50 years or older, treatment with EPA-DHA or vitamin D3, compared with placebo, resulted in no significant difference in the risk of incident AF over a median follow-up of more than 5 years. The findings do not support the use of either agent for the primary prevention of incident AF.Trial registrationClinicalTrials.gov Identifiers: NCT02178410; NCT01169259.

Project description:ObjectiveTo investigate whether vitamin D and marine derived long chain omega 3 fatty acids reduce autoimmune disease risk.DesignVitamin D and omega 3 trial (VITAL), a nationwide, randomized, double blind, placebo controlled trial with a two-by-two factorial design.SettingNationwide in the United States.Participants25 871 participants, consisting of 12 786 men ≥50 years and 13 085 women ≥55 years at enrollment.InterventionsVitamin D (2000 IU/day) or matched placebo, and omega 3 fatty acids (1000 mg/day) or matched placebo. Participants self-reported all incident autoimmune diseases from baseline to a median of 5.3 years of follow-up; these diseases were confirmed by extensive medical record review. Cox proportional hazard models were used to test the effects of vitamin D and omega 3 fatty acids on autoimmune disease incidence.Main outcome measuresThe primary endpoint was all incident autoimmune diseases confirmed by medical record review: rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease, psoriasis, and all others.Results25 871 participants were enrolled and followed for a median of 5.3 years. 18 046 self-identified as non-Hispanic white, 5106 as black, and 2152 as other racial and ethnic groups. The mean age was 67.1 years. For the vitamin D arm, 123 participants in the treatment group and 155 in the placebo group had a confirmed autoimmune disease (hazard ratio 0.78, 95% confidence interval 0.61 to 0.99, P=0.05). In the omega 3 fatty acids arm, 130 participants in the treatment group and 148 in the placebo group had a confirmed autoimmune disease (0.85, 0.67 to 1.08, P=0.19). Compared with the reference arm (vitamin D placebo and omega 3 fatty acid placebo; 88 with confirmed autoimmune disease), 63 participants who received vitamin D and omega 3 fatty acids (0.69, 0.49 to 0.96), 60 who received only vitamin D (0.68, 0.48 to 0.94), and 67 who received only omega 3 fatty acids (0.74, 0.54 to 1.03) had confirmed autoimmune disease.ConclusionsVitamin D supplementation for five years, with or without omega 3 fatty acids, reduced autoimmune disease by 22%, while omega 3 fatty acid supplementation with or without vitamin D reduced the autoimmune disease rate by 15% (not statistically significant). Both treatment arms showed larger effects than the reference arm (vitamin D placebo and omega 3 fatty acid placebo).Study registrationClinicalTrials.gov NCT01351805 and NCT01169259.
