Foot self-care behaviour in type 2 diabetes adults with and without comorbid heart failure.

AIMS: To compare the correlates of foot self-care behaviours among type 2 diabetes mellitus (T2D) adults with and without comorbid heart failure (HF). DESIGN: Cross-sectional, correlational, comparative design. METHODS: A 210 T2D adults (105 with HF and 105 without HF) participated from August-December 2020. Foot self-care behaviour was measured using the foot care subscale of the Summary of Diabetes Self-Care Activities (SDSCA) instrument. A stepwise logistic regression analysis was used to explore variables predicting foot self-care behaviour. RESULTS: The participants' mean age was 58.7 ± 10.9 years. Poor foot self-care behaviour was reported in T2D adults both with (53.3%) and without (54.3%) HF. Participants with HF-comorbidity were statistically significantly older and had higher total daily medication intake. Household income and the total number of daily medications statistically significantly predicted foot self-care behaviour in HF-comorbid T2D adults. Marital status, social support and body mass index predicted foot self-care behaviour in the non-HF group.

Relationships of diabetes self-care behaviours to glycaemic control in adults with type 2 diabetes and comorbid heart failure.

Aim: To describe the relationship between diabetes self-care behaviours and glycaemic control in patients with type 2 diabetes and comorbid heart failure. Design: A cross-sectional, correlational study. Method: A secondary analysis of 180 participants' baseline data from a clinical trial that tested a 6-month integrated self-care intervention was performed. Correlational and hierarchical linear regression analysis was used to assess the relationships between diabetes self-care behaviours and glycaemic control. Result: The Summary of Diabetes Self-Care Activities general diet and Summary of Diabetes Self-Care Activities exercise were negatively associated with glycated haemoglobin (HbA1c), while Summary of Diabetes Self-Care Activities specific diet was positively associated. Diabetic end-organ failure, taking insulin only and taking both oral antiglycaemic and insulin, predicted higher HbA1c and fasting blood glucose. African American race and dyslipidaemia predicted higher HbA1c while taking higher total daily medication predicted higher fasting blood glucose. Longer years lived with heart failure, lower ventricular ejection fraction and exposure to chemotherapy predicted lower fasting blood glucose.

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

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 self-efficacy 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 urban-tertiary 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.

Correlates of Self-Care Behaviors in Adults With Type 2 Diabetes and Comorbid Heart Failure.

PURPOSE: The purpose of this study was to describe sociodemographic, clinical, and psychosocial correlates of diabetes self-care behaviors in adults with type 2 diabetes mellitus (T2D) and comorbid heart failure (HF). METHOD: Baseline data of 180 participants from a clinical trial that tested a 6-month integrated self-care intervention for persons with comorbid HF and T2D were analyzed. Correlational bivariate and multiple logistic regression analyses were performed to examine correlates of diabetes self-care behaviors. RESULT: Participants had a mean age of 58 ± 11years; the majority were male (n = 118, 66%) and African American (n = 119, 66%). Number of comorbidities >2 (P < .001), having more than a high school education (P < .05), and African American ethnicity (P < .05) predicted better exercise, self-monitoring blood glucose (SMBG), and foot care behaviors, respectively. The use of an aldosterone inhibitor (P < .05) predicted worse exercise performance, higher Charlson Comorbidity Index scores (P < .01) predicted worse SMBG, and treatment with diet plus medication (P < .05) and dyslipidemia (P < .001) predicted worse foot care. CONCLUSION: Findings from this study provide new insights into the complex self-care requirements for T2D patients with comorbid HF. Integrated self-care interventions are clearly warranted in persons living with multiple chronic conditions for optimal health outcomes and the prevention of complications. Our sample of predominately African American men showed they had better T2D self-care behaviors than whites than previously reported. Additional research is needed to determine racial and gender differences on health outcomes in persons with T2D and comorbid HF.
