Impact of Structured Nutrition Education on Knowledge, Attitude, and Practice among Dyslipidemic Subjects: A Six-Month Quasi-Experimental Study

Abstract

Dyslipidemia, characterized by elevated total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, and reduced high-density lipoprotein cholesterol (HDL-C), is a major metabolic disorder contributing substantially to global cardiovascular morbidity and mortality. Dietary modification remains a primary strategy for managing dyslipidemia. Knowledge, Attitude, and Practice (KAP) assessments provide an effective framework for evaluating nutrition-related awareness and behaviours, as well as the impact of educational interventions. The present study evaluated the effectiveness of a structured nutrition education program among dyslipidemic subjects over a six-month period. A quasi-experimental design was employed, consisting of an experimental group receiving the intervention and a control group receiving no educational support in a clinical settings. Baseline KAP scores were assessed using a validated questionnaire. The intervention included a series of structured educational sessions in a group form delivered through audio-visual aids such as charts, posters, pamphlets, and instructional videos. Nutrition education was given six weekly sessions to subjects. Follow-up assessments were conducted at the end of six months to measure changes in KAP scores in both groups. Results demonstrated that participants in the experimental group exhibited significant improvements in knowledge (31.44%), attitude (30.76%), and practice (46.05%), while the control group showed no meaningful changes across these domains. These findings confirm the effectiveness of structured nutrition education in enhancing awareness, fostering positive attitudes, and promoting healthier dietary practices among dyslipidemic individuals. Overall, this study underscores the essential role of evidence-based nutrition education in facilitating behavioural modification, supporting dietary adherence, and ultimately contributing to the reduction of cardiovascular risk.
