糖尿病是老人常見的疾病，其盛行率隨著年齡的增加而上升，也常出現許多合 併症，糖尿病控制的目標就是將血糖控制在理想範圍，需仰賴自我照顧行為成 效。本文目的在探討第二型老年糖尿病病人自我效能、社會支持與自我照顧行為 之相關，以及與自我照顧行為有關的重要變項。本研究採橫斷性、描述性相關性 研究設計，以北部某醫院糖尿病共照網之236位老年糖尿病人為研究對象，收案時 間為2015年4月到10月，以人口學變項、自我效能、社會支持與自我照顧行為等 量表進行資料收集。結果顯示（1)總自我照顧跟飲食自我照我跟體重有統計上顯 著意義存在。（2)運動自我照顧跟治療方式有統計上顯著意義存在。（3)血糖自 我照顧跟教育有統計上顯著意義存在。（4)自我效能及社會支持都與自我照顧行 為呈現顯著正相關。（5)自我效能、社會支持及性別共可解釋82.9%的總變異量。 本研究提出以下結論:自我效能及社會支持在自我照顧跟血糖的控制上扮演了很重 要的角色，本研究結果可以提供臨床護理照護介入措施之參考。

Diabetes is a common disease for the elderly. With the increasing of the aging population, the prevalence of diabetes is increasing year by year and has become a noncommunicable chronic disease which is seriously harmful to the older adult health. Self-care behaviors play an important role in the control of blood sugar. The purpose of this study was to investigate the relationships between self-efficacy, social support and self-care of older people with diabetes mellitus. In this study, a cross-sectional survey was conducted with a total of 236 type 2 diabetes elderly patients recruited from the outpatient Diabetes Shared Care Department of a medical center in northern Taiwan. Data were collected from April to October, 2015. A set of questionnaires that included demographic characteristics; self-efficacy; social support; and self-care were administered. Result showed significant relationships of self-care with body weight, education, medication adherence, self-efficacy, and social support (p< .05). Self-efficacy, social support, and gender accounted for 82.9% of the variability in self-care. Diabetes self-efficacy may play an important role in diabetes self-care and ultimately in glycemic control. Social determinants should also be taken into account when developing patient self-care goals.
