ABSTRACT
BACKGROUND:
Dietary supplement use is common in older adults. There has been limited research in people attending memory clinics.OBJECTIVES:
To explore the use of dietary supplements in older people attending Australian memory clinics.DESIGN:
Cross-sectional analysis of baseline data from the Prospective Research In MEmory clinics (PRIME) study.PARTICIPANTS:
Community-dwelling older people who attended nine memory clinics and had a diagnosis of mild cognitive impairment (MCI) or dementia. MEASUREMENTS Dietary supplement was defined as a product that contains one or more vitamin, mineral, herb or other botanical, amino acid or other dietary substance. Non-prescribed supplement was defined as a supplement that is not usually prescribed by a medical practitioner. Polypharmacy was defined as use of five or more medications.RESULTS:
964 patients, mean age 77.6 years, were included. Dietary supplements were used by 550 (57.1%) patients; 353 (36.6%) used two or more. Non-prescribed supplements were used by 364 (36.8%) patients. Supplement use was associated with older age (OR 1.12, 95% CI 1.03-1.21), lower education level (OR 1.53, 95% CI 1.01-2.32) and a diagnosis of MCI rather than dementia (OR 1.52, 95% CI 1.05-2.21). Potential drug-supplement interactions were identified in 107 (11.1%) patients. Supplement users had increased prevalence of polypharmacy compared to non-users (80.5% vs. 48.1%, p<0.001).CONCLUSIONS:
Dietary supplements, including non-prescribed supplements, were commonly used by people attending memory clinics. Supplement use increased the prevalence of polypharmacy and resulted in potential supplement-drug interactions. Further research is required to assess the clinical outcomes of supplement use.
