Healthcare Mistreatment and Cultural Beliefs Impact HbA1c in Patients with Type 2 Diabetes Mellitus

Abstract

The aim of this research was to examine the effects of healthcare mistreatment and cultural beliefs on psychological, behavioral, and biological phenomena relevant to treatment adherence and health outcome among patients with Type 2 Diabetes Mellitus (T2DM).  The study was conducted in Chile, where the prevalence of T2DM is one of the highest in Latin America and is increasing at an accelerated rate. The research was guided by Betancourt’s Integrative Model and bottom-up mixed-method cultural research approach. Consistent with the hypotheses of the study, the test of a structural equation model based on the Integrative Model, including exposure to healthcare mistreatment, diabetes-related cultural beliefs, psychological distress, and medical avoidance as determinants of HbA1c, a biological measure of diabetes control, fit the data. The fact that the analysis of structural equations accounted for significant variance in HbA1c provides supporting evidence for extending the Integrative Model, to explain biological phenomena based on cultural and psychological factors.
