title: Medication use in community-residing older adults in Taiwan: a comparison between conventional and complementary and alternative medications.
abstract: Older adults are at risk of problems of medication use including underuse, overuse, and misuse. The purposes of this study were to investigate the prevalence of the use of conventional and complementary and alternative medications (CAM) in older adults and to explore which factors related to their medication use. For this descriptive correlational study, 1,427 citizens who were 65 years old or older from two towns in Yilan County, Taiwan were interviewed by ten trained public health nurses between June and September, 2013. Instruments in this study were physical functional capacity, depressive symptoms, and medication use. Pearson product-moment correlation analysis and the Chi-square test were used to detect relationships among research variables. Of the 1,427 participants, 75.4 % used at least one type of conventional medication, and the average number of medications used was 2.9 (SD = 2.1). Polypharmacy (the use of five or more medications) was identified in 20.1 % of participants. Significant factors related to conventional medications use were older age (χ(2) = 41.7***), female (χ(2) = 7.6**), bad memory (χ(2) = 11.2**), defect cognition status (χ(2) = 7.8**), lost the interest to do anything depressive symptoms (χ(2) = 7.2**), and independent in their daily activities (χ(2) = 41.3***). We found that sociodemographic characteristics and factors pertaining to health status determine the difference between the use of conventional medications and CAM by rural older adults. Our study results suggested that health professionals in Taiwan must be educated and trained in how to integrate CAM into current conventional treatment.
