本研究旨在探討中高齡者電子健康素養與電子健康服務使用現況及關係。本研究以中高齡網路使用者為研究對象，在2020年透過網路方式調查中高齡者之個人背景、電子健康素養及電子健康服務使用等資料，共計回收566份有效問卷，研究結果顯示：
一、中高齡者電子健康素養為中等程度，電子健康素養會因年齡、性別、教育程度、經濟狀況、就醫狀況、網路使用年資不同而有顯著差異。
二、中高齡者有64.8%會使用醫療服務應用程式，進行預約掛號、看診、領藥進度查詢及繳費等功能，多元邏輯斯回歸分析顯示女性、大學程度、月收入較高、需要規律返診及電子健康素養較高者，較可能會使用醫療服務APP。
三、中高齡者有23.5%會使用健康管理應用程式，來進行體重管理、飲食、運動、血壓紀錄管理；另外有40.3%中高齡者會使用穿戴式電子裝備(如智慧手環、手錶)來進行計步、運動等紀錄，多元邏輯斯迴歸分析顯示，有慢性疾病及電子健康素養較高者，較可能會使用健康管理APP及穿戴式電子裝備。
四、高齡者有44.3%中會加入健康網站社群媒體平台，查看最新健康資訊，多元邏輯斯迴歸分析顯示，女性及電子健康素養較高者，較可能會加入健康網站社群媒體平台。
建議未來可強化中高齡者電子健康素養能力培養，以提升電子健康服務之利用。

This study aimed to explore the relationship between electronic health (e-health) literacy and electronic health services use among middle- to older-aged adults. A total of 556 adults completed online survey in 2020. The results were as follows.
The middle- to older-aged adults had intermediate e-health literacy. Adults’ age, gender, educational level, economic status, medical status, and internet use were associated with e-health literacy.
Sixty-four percent of adults used medical services applications (apps) for outpatient appointment, drug inquiry and online payment. Multiple logistic regression analysis showed that adults who were women, college-educated, had higher income, e-health literacy and regular outpatient visits were more likely to use medical services apps.
Twenty-three percent of adults used health management apps for weight and blood pressure management, while forty percent of adults used wearable electronic devices for physical activity tracking. Adults who had chronic diseases and higher e-health literacy were more likely to use health management apps and wearable electronic devices.
Forty-four percent of adults used health-related websites or social media to obtain health information. Adults who were women and had higher e-health literacy were more likely to use health-related websites and social media.
It was suggested that fostering e-health literacy among adults might enhance the utilization of e-health services.
