Objective: Because hyperlipidemia is asymptomatic, many veterans affairs (VA) patients may not perceive it seriously. We assessed key Health Belief model concepts to describe patients' cholesterol-related health beliefs and examine associations between patient-level factors and desire to improve cholesterol control.
Methods: We used baseline data from an ongoing randomized clinical trial. Eligible patients were receiving care at the Durham VA and had CVD risk-total cholesterol levels >130 mg/dL and/or <80% medication adherence in the previous 12 months. A survey assessed patients' health beliefs about high cholesterol and self-reported medication adherence. Multivariable logistic regression examined whether there was an association between desire to control cholesterol and cholesterol status.
Results: Approximately 64% (n=155) of patients perceived high cholesterol as 'very serious'. In multivariable logistic regression analysis, patients who perceived high cholesterol as 'very serious' (OR 2. 26, p=0.032) and/or with high self-efficacy (OR 4.70, p<0.001) had increased odds of desiring cholesterol control.
Conclusion: The factors most significantly associated with desire to improve cholesterol control were perceiving hyperlipidemia as 'very serious and self-efficacy for cholesterol control.
Practice implication: Educating patients, with the goal of appropriately increasing their perceived risk of disease, is likely necessary to impact cholesterol control.
