Self-care behaviours and their determinants in people affected by coronary heart disease

Objective: To describe self-care in Italian adults with coronary heart disease and to identify sociodemographic and clinical determinants of self-care. Design: This is a cross-sectional analysis of data from the Italian multicentre longitudinal study. Methods: We used the follow instruments: Self-Care of coronary heart disease inventory, Self-care Self Efficacy Scale, Charlson Comorbidity Index and Sociodemographic questionnaire. Descriptive statistics including absolute numbers, percentages, means and standard deviations were used to describe the sociodemographic and clinical characteristics of the sample, and the items. A structural equation model was fitted to understand sociodemographic and clinical variables associated with self-care, and possible effects mediated by self-efficacy. Results: We enrolled 427 patients. Self-care maintenance, monitoring, management and self-care self-efficacy means scores were 58.27 (SD = 20.07), 48.53 (SD = 26.97), 65.34 (SD = 22.85) and 77.16 (SD = 20.76), respectively. Except for the self-care self-efficacy scale, all the scores lay below the cut off 70 for adequacy. Older age, higher comorbidities, a higher number of stents placed, and the presence of a caregiver predicted poor self-care. Conclusion: Self-care in Italian CHD populations is poor. Several associations were found between the dimensions of self-care and sociodemographic factors. Implications for the profession these findings are important for health care providers to plan interventions to improve self-care behaviour.
