Abstract

BACKGROUND AND RESEARCH OBJECTIVES:

Adherence to a medication regimen is a major factor in achieving adequate blood pressure control for hypertensive patients. However, older adults often report having missed doses, which they attribute to forgetfulness. The purpose of this study was to identify significant factors, including socioeconomic variables, hypertension history, and cognitive functions, contributing to medication adherence among older Korean adults with hypertension.

SUBJECTS AND METHOD:

This study involved 241 older patients with hypertension from a community senior center during the period from 2008 to 2009. Data were collected through face to face interviews. The association of medication adherence with socioeconomic characteristics, hypertension-related history, knowledge, antihypertensive lifestyle, and memory was assessed by computing odds ratios in logistic regressions.

RESULTS AND CONCLUSIONS:

Of the 241 patients, 44% were aged 75 or older, and 60% were male. The rate of non-adherence with antihypertensive medication was 41%. Metamemory, adherence to an antihypertensive lifestyle, and employment status, were associated with participants' adherence to antihypertensive medication in both univariate and multivariate analyses. Results suggest that memory functions are a key factor to medication adherence among the Korean elderly population. In contrast to younger adults, unintentional non-adherence appears to be a major issue for older adults to keep medicating. Interventions focusing on memory ability, such as strategies for recalling and placing cues, are needed for implementation in the population of older Korean patients with hypertension. Unemployed older people who have hypertensive lifestyles should also be considered a high-risk group for non-adherence to medication.
