Glycaemic control mediates the relationships of employment status and self-stigma with self-care behaviours in young adults with type 2 diabetes

Aims and objectives: To investigate the relationships of sociodemographic factors, self-stigma, glycaemic control (measured by glycated haemoglobin (A1C)) and self-care behaviours in young adults with type 2 diabetes. Background: Young adults aged 25–44 years are in their most productive period. Once diagnosed with diabetes, this population tends to experience poor glycaemic control and perform poorly in self-care activities. Such patterns may raise perceptions of self-stigma and further decrease motivations to engage in self-care behaviours in patients with diabetes. Design: A cross-sectional, correlational research design. Methods: The STROBE guidelines for cross-sectional studies were followed. A convenience sample of 115 participants was recruited from a medical centre in southern Taiwan. Instruments included the Self-Stigma Scale–Chinese version and the Diabetes Self-Care Behaviours Scale. Data were analysed using a three-step hierarchical regression analysis and the Sobel test. Results: The average age of the participants was 36.7 years. Marital status, employment status, self-stigma and A1C were significantly associated with self-care behaviours, and these four variables explained 43.6% of the variance in self-care behaviours. However, A1C (β = −.58, p <.001) was found to be the only determinant of self-care behaviours in the last regression model. The Sobel test showed that A1C had mediating effects on self-stigma and self-care behaviours as well as employment status and self-care behaviours. Conclusion: This study supports the interactive relationship among self-stigma, employment status, glycaemic control and self-care behaviours in young adults with type 2 diabetes. Strategies aimed at optimising glycaemic control can help reduce the effects of self-stigma perceptions and employment status on the self-care behaviours of such patients. Relevance to clinical practice: More effective educational programmes should be designed to improve glycaemic control, lower the effects of employment and decrease perceptions of self-stigma to further motivate young adults to engage in better diabetes self-care behaviours.
