Résumé : Although combined changes in eating habits and physical activity are pivotal to hypercholesterolemia management and the prevention of cardiovascular disease, little is known about the factors influencing the adoption of both behaviors by adults with hypercholesterolemia. The goal of this study was to identify psychological factors that predict a combined adoption of dietary modification and physical activity among adults with hypercholesterolemia. We recruited a sample of 1100 adults with hypercholesterolemia (56.9% male, mean age=56.5 years) through a nationally representative online panel. Participants reported their physical activity using the International Physical Activity Questionnaire (IPAQ) and their eating habits using a Food-Frequency Questionnaire (FFQ). We assessed a comprehensive set of psychological variables, including hypercholesterolemia knowledge and perception, patient's cardiovascular history, doctor–patient relationship, social-cognitive beliefs, and personality traits. Based on IPAQ and FFQ scores, we classified participants into four groups (dietary modification plus physical exercise, dietary modification, physical exercise, passive). Our analysis showed that subjective hypercholesterolemia knowledge, beliefs about the effects of hypercholesterolemia, external locus of control (other people and chance), nutrition and physical exercise self-efficacy, and trait self-control significantly influenced the simultaneous adoption of physical exercise and dietary modification. This study highlights the importance of psychological factors in predicting the combined adoption of physical exercise and dietary modification among adults with hypercholesterolemia. Addressing these factors could help improve hypercholesterolemia prevention strategies.
