To describe the use of oral complementary medicine (CM) in people with inflammatory arthritis.
The Australian Rheumatology Association Database (ARAD), an observational database, collects outcome data from people with rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA) and juvenile idiopathic arthritis (JIA). Participants complete semi-annual then annual questionnaires. CM use from baseline questionnaire for participants recruited between 2006 and 2016 was categorised into fatty acids (eg. fish oil, evening primrose oil), herbs (eg. ginger, turmeric) or supplements (eg. glucosamine, vitamins). Changes in CM use over time were also determined.
Of 4,425 ARAD participants 43.4% were taking CM at enrolment (RA: 1,324 (45.7%), AS: 261 (40.7%), PsA 307 (43.2%), JIA: 31 (17.7%)). Use was more prevalent in women (OR 1.37; 95%CI 1.25-1.59), those with tertiary education (OR 1.26; 95%CI 1.10-1.44), private health insurance (OR 1.30; 95%CI 0.1.21-1.52), drinking alcohol sometimes compared to never (OR 1.24; 95%CI 1.06-1.44), and less prevalent in current smokers (OR 0.75; 95%CI 0.62-0.91). Levels of pain in the last week were not different between CM uses and non-users (OR 1.00; 95%CI 1.00-1.00).
Overall, 35% were taking fatty acids, 7% herbs and 19% supplements. The most common CMs were fish oils (1,489 (34%)) followed by glucosamine (605 (14%)), although both have declined in use over the last decade (fish oil 2006-2016: 31%-28%, p=0.85; glucosamine 20%-9%, p=<0.001). Over time, there has been increased use of supplements, particularly vitamin D (2006-2016: 1.6%-3.3%, p<0.001) and magnesium (2006-2016: 0.4%-2.7%, p=0.02), turmeric has also increased (2006-2016: 0%-1.2%, p<0.001), while the use of krill oil has declined (2012-2016: 3.9%-0.3%, p<0.001) and calcium has remained level (2006-2016: 3.0%-2.4%, p0.71).
Just under half of ARAD participants were taking CM at ARAD entry. Types of CM used by people with inflammatory arthritis appear to change over time but appear to have no influence on levels of pain. Further research could investigate what prompts use of these products.
