Effects of intervention on lifestyle changes among coronary artery disease patients: A 6-month follow-up study

Abstract

Aim: The main aim of the study was to investigate the effects of a nurse-led lifestyle-related risk factor modification intervention on multiple lifestyle behaviours among coronary artery disease patients over six months. Design: A pre-test post-test control group design was conducted in a single clinical centre in Nepal. Methods: A total of 224 eligible patients were randomly assigned to either the usual care group or the intervention group at baseline. The lifestyle intervention consisted of a brief counselling session supplemented with informational leaflets. Standard questionnaires were used to collect self-reported data from patients on multiple lifestyle behaviours: diet, physical activity, adherence to medication, stress, body mass index, smoking and alcohol consumption. General linear model repeated measure analysis was used to estimate the effect of intervention. Results: A statistically significant effect of study group-by-time interaction for diet, adherence to medication, physical activity, and perceived stress was found at 6-month follow-up. Overall, greater improvement in lifestyle habits was found in the intervention group compared with the control group at 6-month follow-up.
