- Serum levels of Biomarkers of Systemic Inflammation [ Time Frame: 5 years ]Blood samples at baseline and in follow-up will be collected and analyzed for changes in biomarkers of systemic inflammation: C-reactive protein, interleukin-6, and tumor necrosis factor-receptor 2. We will test whether either or both supplements are associated with a decrease in the biomarkers of systemic inflammation (blood biomarker levels among those receiving supplements vs. placebo).
- Severity of Knee Pain [ Time Frame: 5 years ]Participants with chronic, frequent knee pain at trial baseline will be followed with annual questionnaires to test for decrease in severity of chronic knee pain in those taking supplements compared to those taking placebo. We will test whether either or both supplements are associated with reduced levels of knee pain at the end of the trial (comparing knee pain outcomes in those receiving supplements to placebo).
- Incident Autoimmune Diseases [ Time Frame: 5 years ]All participants will be followed for the development of new autoimmune diseases, including, but not limited to, rheumatoid arthritis, psoriasis, autoimmune thyroid disease, inflammatory bowel disease and polymyalgia rheumatica.
- Interactions between the effects of vitamin D and those of fish oils for each of the primary outcomes [ Time Frame: 5 years ]We will test for interactions between the effects of vitamin D and those of fish oils for each of the primary outcomes above: (A) whether either or both supplements are associated with reduced numbers of new cases of autoimmune diseases; (B) whether either or both supplements are associated with reductions in biomarkers of systemic inflammation and; (C) whether either or both supplements are associated with reduced levels of knee pain at the end of the trial.
- Subgroup analysis of primary outcomes [ Time Frame: 5 years ]We will test for differential effects of and interactions between vitamin D and fish oils for each of the three primary outcomes, according to participant age, race, sex and BMI. We will test for these interactions for each of the primary aims above: (A) whether either or both supplements are associated with reduced numbers of new cases of autoimmune diseases; (B) whether either or both supplements are associated with reductions in biomarkers of systemic inflammation and; (C) whether either or both supplements are associated with reduced levels of knee pain at the end of the trial.
