Analysis of moderating effect of health literacy between symptom burden and disease uncertainty in patients with chronic heart failure
Objective To explore the relationship between symptom burden and disease uncertainty in patients with chronic heart failure(CHF),and verify the moderating effect of health literacy on symptom burden and disease uncertainty.Methods A total of 234 patients with CHF who were hospitalized in the First Affiliated Hospital of Wenzhou Medical University from April 2021 to April 2022 were selected by convenience sampling method.Memorial symptom assessment scale-heart failure,Mishel uncertainty in illness scale for adult,and health literacy management scale were used for questionnaire surveys.Multiple linear regression was used to verify the moderating effect of health literacy on symptom burden and disease uncertainty in CHF patients.Results The symptom burden of CHF patients was positively correlated with disease uncertainty(r=0.497,P＜0.01),and negatively correlated with health literacy(r=-0.252,P＜0.01),health literacy was negatively correlated with disease uncertainty(r=-0.593,P＜0.01).Moderating effect analysis showed that health literacy had a moderating effect between symptom burden and disease uncertainty in CHF patients(β=-0.258,P＜0.05).Simple slope analysis showed that when the health literacy level of CHF patients was high,symptom burden had less positive predictive effect on disease uncertainty(simple slope=6.817,P＜0.05).Conclusion The symptom burden of CHF patients can affect the level of disease uncertainty and is regulated by health literacy.Nursing should pay attention to the effect of symptom burden on the level of disease uncertainty in CHF patients,and formulate interventions to reduce the symptom burden and improve health literacy,so as to reduce the level of disease uncertainty.
