Effect Of Nutrition Education And Passive Dietary Intervention On Metabolism Of Lipids And Related Chronic Disease In Middle-Old-Age Population Of Community

· Objective1) To determine the effect of nutrition education and passive dietary intervention on metabolism of lipid and related chronic disease in middle and old aged persons of community.2) To compare single nutrition education with nutrition education plus passive dietary intervention.3) Finding out difference between education by one-way media and by two-way (face to face) media.· Methods (Education and Intervention)1) Take an investigation of basic nutritional state and acquire general information from the 1017 residents no younger than 45 years from the Yijiangmen Communities in Nanjing City.2) After medical check-up and base investigation, 260 persons who have hyperlipemia, hypertension or diabetes were selected as study population.3) Participants were randomized to 3 groups: (1)"the passive dietary intervention group", is given 100g coarse food grain everyday and nutrition education;(2)"the nutrition education group", is only given nutrition education ;(3)"the control group", accepts education by one-way media, such as TV and broadcast.· Results1) Base investigation show that the prevalence of hyperlipemia, hypertension and diabetes are 53.91%, 27.63% and 6.22% separately.2) After three month, The average value of triglyceridcs (TG), cholesterol (TC), blood sugar (GLU) and systolic blood pressure (SPB) decreased by 1.22mmol/L (P<0.0001), 0.59mmol/L (P<0.05), 1.86mmol/L (P<0.0001) and 3.30mmHg(P<0.05) respectively in the passive dietary intervention group.3) In the nutrition education group, the determination of TG, TC and GLU are cut down 0.83mmol/L (P<0.0001), 0.24 mmol/L (P<0.05) and 0.76 mmol/L(P<0.0001).4) The mean net reduction in TG is 0.37mmol/L (P<0.0001) of the control group.5) The KAP (knowledge, attitude and practice) investigation show there are significant difference in attitude and practice among three groups (p<0.0001) after intervention and education for three month.· Conclusion and Aadvice1) There are better effect on decreasing in blood lipids, blood pressure and blood sugar of nutrition education plus passive dietary intervention than of single nutrition education.2) Influence of education by two-way media on modification of healthy attitude and practice is power than by one-way (face to face) media.3) That is crux to establish the network-system, working-mechanism and pattern, feasible methods of dietary intervention and nutrition education.4) Government and experts ought to go to communities to support education and intervention of nutrition for building health community.
