비알코올성 지방간 환자를 위한 저탄수화물·저단순당 영양교육매체 개발 및 순응도 평가

Abstract

We developed nutrition education materials for non-alcoholic fatty liver disease (NAFLD) patients. Above all, we decided five education sections which are consist of three or four topics each and gained information from diverse references to set the education contents. After that, the contents were organized with two forms that booklet for face-to-face education and handout for phone call education. With the final materials, we conducted an application evaluation to know whether it is applicable for general NAFLD patients among Korean adults aged 20-70 years. A total of 106 subjects were recruited from the 5 participating general hospitals in Seoul metropolitan region. The subjects were ramdomly divided in case(Low carbohydrate and low simple sugar diet) and control(Low fat diet) groups. Simple information on socio-demographic characteristics were obtained through a interview using a structured questionnaire. Nutrition education for NAFLD was conducted by a trained dietitian using the developed education materials for 6weeks. We checked up the subjects’ subjective difficulty and compliance three times during the education period through interview and phone call. The study protocol was approved by the IRB at each participating institution. As a result, there were no significant differences in main characteristics including age, weight, BMI, waist circumference, blood pressure, and fasting glucose between cases and controls. In subjective difficulty, case group thought the low carbohydrate and low simple sugar diet is ‘a bit difficult’ at first(p<0.035*), but there was no significant difference between case and controls at the second and third evaluation. Also both groups responded the diet was ‘relatively well practicable’ in subjective compliance evaluation. In conclusion, the developed nutrition education materials and low carbohydrate and low simple sugar diet are applicable for general Korean NAFLD patients as well as traditional low fat diet.
