Aim: The aim of present study was to describe the prevalence of medication adherence, and to examine its risk factors among Chinese community-dwelling older adults with chronic diseases. Methods: Secondary analysis was carried out on the data collected from 3167 Hong Kong adults aged ≥60years who lived in their private home, had at least one type of chronic disease and had completed a screening instrument for long-term care services for the first time in 2006. The outcome variable was the self- or caregiver-reported medication adherence. Results: Among the respondents, 90.8% reported having good medication adherence in the past 7days. More dependence on activities of daily living (P<0.001), stroke (P=0.003) or diabetes (P=0.036), had medication review by physicians (P<0.001) and received more informal care support (P=0.005) were positively associated with medication adherence, whereas more cognitive impaired (P=0.008), more negative mood (P=0.071) and perceived poor health (P<0.001) were negatively associated with medication adherence. Conclusions: The prevalence of self-reported medication adherence was high in Hong Kong Chinese community-dwelling older adults. A number of modifiable factors associated with medication adherence were identified, which provides specific targets for interventions.
