JOURNAL OF SCIENCE, Hue University, N0 61, 2010 ASSESSMENT OF HEALTH EDUCATION OUTCOMES ABOUT DYSLIPIDEMIA, USING A NETWORK OF COMMUNITY HEALTH WORKERS IN HUE CITY Doan Phuoc Thuoc College of Medicine and Pharmacy, Hue University Nguyen Thi Kim Tien Vietnam's Ministry of Health SUMMARY Dyslipidemia is very common in the community and is an important risk factor of atherosclerosis and coronary artery disease with high mortality. A community intervention of health education is designed to progressively reduce dietary intake of satuprevalenced fats, cholesterol, total calories and increase physical activities to decrease dyslipidemia. The intervention was conducted by a network of medical staffs in wards and intergprevalence with other health programmes. After 12 months of intervention, the prevalence of dyslipidemia decreased 11.6% (from 39.3% to 27.7%). The prevalence of high serum total cholesterol (TC) levels reduced from 20.4% to 11.1%, LDL-C levels reduced from 15.7% to 6%, triglicerides levels did not change. Average values of serum HDL-C levels increased (from 53.6 mg / dL to 63.9 mg / dL) and LDL-C levels reduced (from 119.4 mg / dL to 100.6 mg / dL) (p
secondary causes (lifestyle habits) play an important role in the process of dyslipidemia, including high fat diet, sedentary lifestyle, few physical activities, drinking too much alcohol (lifestyle factors) and poor knowledge of dyslipidemia. The fact that changing lifestyle habits will reduce prevalence of dyslipidemia and coronary disease risk has been identified in developed countries. In Vietnam in general and Hue city particularly, the education program related to dyslipidemia is very limited, so detection, prevention and treatment of dyslipidemia does not receive adequate concern. Doctors in hospitals often use drugs to treat those individuals with dyslipidemia. It's important in health care strategy to reduce the morbidity in community and increase the prevalence of detection and treatment to have long term effects. The study "Assessment of health educational outcomes about dyslipidemia using a network of community health workers in Hue City" was conducted to assess the behavioral changes in prevention and treatment of dyslipidemia and evaluate the prevalence of dyslipidemia decreasing in people aged 20 years or older in Hue city through community health education. 2. Methodology - The subjects of the study were adults aged 20 years or older in Hue city - Study design: A community intervention of health education is designed to progressively reduce dietary intake of saturated fats, cholesterol, total calories and increase physical activities to decrease dyslipidemia; the intervention was conducted for 12 months from 3/2008 to 5/2009 by a network of medical staffs in wards and intergrate with other health programmes. - Sample size: 350 adults aged 20 and older, calculated by following formula 2 p (1  p ) F n d2 ▪ F = 7,9; d: difference between dyslipidemia prevalence before (pA) and after (pB) health education; pA : 35.08 % and pB : 25 % (expectantly) - Sample: Choose two wards of Hue city randomly, randomly select five groups (administrative units of ward) per ward, and 35 people aged 20 years and older per group selected according to a list - Methods of data collection: + A community survey to collect data before the community health education on dyslipidemia 468

4. Discussion The intervention of providing lipid education to the community and households was conducted for 12 months, from March, 2008 to May, 2009. The time of the intervention was not long but the improvement was significant. According to Sheri R. Colberg, the improvement was usualy after 6 weeks to 16 weeks and the improvement will be greater after 1 year or longer. To implement interventions in the community, the communication network of community health workers were built, they are included doctors, nurses, pharmacist of wards health center, private clinics, pharmacies and governments officers in wards; they were trained to communication in the community, households, offices, pharmacies, and clinics. Communication was integrated into the implementation of primary health care programs at the ward. These methods of intervention were implemented in many countries around the world and promoted lifestyle change and reduced others risk factors of coronary heart disease (CHD). In 2006, the physical activity and Nutrition programs of the National Center for Disease Control in American has implemented the intervention community to help change people's behavior: 20 social level interventions, 39 community level interventions, 54 organization level intervention, 65 individual level interventions purpose to promote community prevention of obesity, chronic diseases and other health problems through good nutrition and regularly physical activity. In Vietnam, the prevention of non-communicable disease strategy was issued in 2002, and the health sector is implementing and developing it. According to James M. Rippe, Theodore J. Angelopoulos and Linda Zukley (2007) the role of physicians and medical staff in lifestyle change interventions are very important. They recommend patients change their lifestyle and comply with the treatment regime . After one year the lipid communication and education have achieved some results. The prevalence of lipid disorders in people aged 20 and older decreased 11.6%. In the opinion of some authors, improved lipid levels depending on many factors, especially the combination of diet and physical activity, the effect of reducing dyslipidemia is very high when combined diet and physical activity has been noted. Some studies compared the benefits of physical activity and diet in the treatment of lipid disorders, some studies have shown lifestyle intervention with moderate diet combine with regularly physical activity less affect blood lipid levels than the more powerful lifestyle intervention (diet and physical activity more powerful than), improve better blood lipid levels and other risk. In concurrence to reducing the prevalence of lipid disorders, the difference in the mean value of increasing blood HDL-C level and reduction of LDL-C compared with before the intervention was statistically significant. This result is the main target in the treatment of lipid disorders, reducing CHD risk 476
factors. Important factor which reduce the prevalence of dyslipidemia is improvement of the level of knowledge of lipid such as good knowledge of dyslipidemia, risks, causes, prvention, and proper treatment increase after intervention; . Improving the knowledge base to change life habits. The intervention program in the U.S. has increased prevalences of physical activity among adults in the U.S. from 2001 to 2005. Research results in some developed countries, although intervention programes impact but still have some barriers affecting knowledge and awareness of dyslipidemia. Although knowledge of cholesterol in the U.S. has improved in recent years, the involvement of cholesterol treatment is still low in this case. The aforementioned study was conducted on seven groups in the UK, and showed that all participants realize that high cholesterol levels adversely affect health, but few people know their cholesterol levels, some doctors also do not mention tcholesterol problems. The study concluded that knowledge about cholesterol and the risk of CHD is not enough to change behavior. Lipid education in the city of Hue has changed the perception and behavior for people, increasing of detection and treatment of dyslipidemia in the community; after the intervention prevalence of self-lipid testing requirements, understand results of tests and proper treatment increase. It's necessary to maintain and promote behavioral change continuously through communication programs and activities of community health workers network. In the U.S., with the community intervention program, the prevalence of participants screened for cholesterol testing is increasing. The public health organizations have attempted to reduce population increases in blood cholesterol and increase awareness of blood cholesterol. There is a national objective screen 80% of adults aged 20 and older for cholesterol by 2010. 5. Conclusions The results after 12 months of intervention have been shown to lower the prevalence of dyslipidemia 11.6% (from 39.3% to 27.7%), hence the intervention was effective 29.5% not sure what this stat is for. The prevalence of high serum total cholesterol (TC) levels reduced from 20.4% to 11.1%, low serum high density lipoprotein cholesterol (HDL-C) levels reduced from 17.1% to 4.6%, high serum low density lipoprotein cholesterol (LDL-C) levels reduces from 15.7% to 6%, high serum triglicerides (TG) levels did not change. Average values of serum HDL-C levels increased (from 53.6 mg / dL to 63.9 mg / dL) and LDL-C levels reduced (from 119.4 mg / dL to 100.6 mg / dL) (p
fats (from 35.6% to 16.6%) and alcohol, higher intake of vegetables, and fish (from 43.5% to 69.7%). Higher percentage of exercise and sports, walking increases from 33.3% to 71.1%. People who had an average activities time of less than 30 minutes per day reduced from 26.9% to 2.9%; excessive intake of alcohol per day reduced from 37.1% to 6.6%; knowledge of dyslipidemia, dietary and physical activity also improved. There was an increase in the prevalence of people who came clinic to test blood lipid by themselves (from 0.9% to 20.2%) and know results of the test (from 3.2% to 28.8%); an increase in prevalence of treatment dyslipidemia (from 2.3% to 16%); among of them, the application of lifestyle changes in treatment increased from 0.4% to 13.7% (p
