Sociodemographic and clinical correlates of diabetes self‐efficacy in adults with type 2 diabetes and comorbid heart failure

Abstract

Heart failure (HF) is a comorbidity that complicates type 2 diabetes mellitus (T2D) management and increases the chance of death. However, little is known concerning factors related to diabetes self-efficacy in comorbid HF. This secondary data analysis was aimed at describing sociodemographic and clinical correlates of diabetes selfefficacy in adults with T2D and comorbid HF. A correlational design was used to analyze cross-sectional baseline data from a randomized study of 180 participants that tested a 6-month integrated self-care intervention targeting adults with concomitant HF and T2D. Participants were enrolled from one of four large urbantertiary hospitals in Atlanta, GA, during 2010-2013. Data were collected from medical records and self-report. We used stepwise multiple linear regressions to examine variables associated with diabetes self-efficacy. The participants' mean age was 58.1 ± 10.7 years and the majority were male (n = 118; 65.6%) and African American (n = 119; 66.1%). Good self-rated health and presence of implantable cardioverter-defibrillator (ICD) had significant positive relationships with diabetes self-efficacy, while taking both oral antiglycemic medication and insulin, history of depression, cardiac pacemaker, and taking digitalis were negatively related. These variables collectively explained 22.4% of the variation in diabetes self-efficacy. One study implication is that using self-rated health provides a quick, patient-centered assessment to evaluate patient health status. Further studies are warranted to ascertain the pathways linking ICD, pacemaker, and digitalis treatment with diabetes self-efficacy.

The Impact of Self-efficacy and Health Literacy on Medication Adherence and Health-related Quality of Life in Patients with Heart Failure: A Systematic Review

“…An association between higher rates comorbidity has been found with low self-efficacy in patients (26). Diabetes patients with comorbid HF have also confirmed the effective and positive role of self-efficacy in their quality of life (48). Only one study did not find a statistical significance effect of self-efficacy on improved health status (17).…”

“…From a total of 18 approved studies, 1 was conducted in Brazil ( 5), 1 in Serbia (23), 1 in Korea (24), 1 in the Netherlands (25), 1 in Italy (26), 1 in Iran (27), 1 in Singapore (17), and 1 in Taiwan (28). Other studies (19,26,(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48) (34). A gender distribution with a minimum number of male participants (20.5%) was observed in the study of Murray et al (31), whereas the maximum number of male participants (75.5%) was observed in the study of Tung et al except for exception of 2 studies in Asia (24,28) in which all participants were of Asian descent, other studies indicated that the majority of participants were African American (30,31,36,37,40).…”
