on the health of working-age people in all over the world In 2003, there are 171,4 million people suffered from diabetes, it is predicted to be double in 2030 Every day, there are about 8700 people die because of diabetes The prevalence of diabetes is different from each continents and areas In Singapore, the rate is 8,6%, Malaysia is 3,1%; that of Kampomg Cham, Cambodia (2005) of over 25-year-old people is 11% In Viet Nam, Ngo Thanh Nguyen said that, at Bien Hoa (2011), the prevalence of diabetes of over 30-year-old people is 8.1%, including, the diagnosis is about 69,1% Huynh Nhan Hai, (2012), at Vinh Long, the prevalence of diabetes is 19,4%, type diabetes is 7,4% Diabetes is still a burden to economic and society However, the disease can be prevented and managed to have treatment, if it is consulted and treated early Moreover, a balance diet and proper exercises can help reduce the risk of prevalence and complication In Hau Giang, a rice production place of Southwest Vietnam, still a poor province in urbanization Khmer make up 22% of the population They have their own habit, particulars; but have narrow knowledge about diabetes and how to prevent it Through a survey at Nga Bay County Town, in 2009, it is found that the prevalence made up 11,8% and it trends to increase However, there is no research related to the prevalence of diabetes of the Khmer in our country It is essential to determine the prevalence of diabetes, pre-diabetes of the Khmer, find proper methods to prevent the disease Moreover, it is to determine the risk of disease for Khmer and have methods to help medical station to manage diabetes It is shown through the following purposes of the research project: To determine the rate of pre-diabetes, diabetes and some factors related to diabetes of Khmer from 45 years old to over at Hau Giang Province in 2011 To evaluate the effect of some preventive methods of diabetes of Khmer from 45 years old to over at the research area New

type-2 diabetes According to American Diabetes Association (ADA), in 2006, “Type diabetes is a metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency” According to International Diabetes Foundation (IDF), in 2010, “Diabetes is a group of metabolic disorders of carbohydrate metabolism characterized by high blood glucose levels and usually resulting from insufficient production of the hormone insulin or an ineffective response of cells to insulin Type-2 diabetes is characterized by insulin resistance and relative insulin deficiency, one of the two dysfunctions can occur at the time of clinical symptoms of diabetes” “Pre-diabetes is a condition of glucose transformation deficiency which includes Impaired Fasting Glucose – IFG and Impaired Glucose Tolerance – IGT” 1.1.2 Diagnosis and classification of diabetes 1.1.2.1 Diagnosis of diabetes: Standards for diagnosis of diabetes and blood sugar disorder of WHO – IDF in 2008 updated in 2010 and the diagnosis standards of ADA/WHO in 2010: thuc.trang.benh.dai.thao.duong

5,6 mmol/l 1.1.2.2 Classification of diabetes According to American Diabetes Association and European Diabetes Association - Type diabetes: the beta cells are destroyed by the immune system and no longer secrete insulin It can be divided into two categories: structure with and without autoimmune It does not depend on cytoplasmic antibodies - Type diabetes: It is characterized by insulin resistance, relative insulin deficiency, and increased production of glucose by the liver, abnormal fat transformation Obesity caused from visceral fat or central obesity - Other specific types: Diabetes due to absent beta cell function or absent insulin action due to genetics - Gestational diabetes: occur while being pregnant 1.1.3 Factors related to Type diabetes In recent years, people have proved that there are many factors related to diabetes According to American National Institute of Health, factors that can cause Type diabetes include: - People ≥ 45 years old, 90-95% suffers from Type diabetes - Overweight (BMI ≥ 23 for Asian people) male pattern obesity (waist size ≥ 90 cm to male and ≥ 80 to female, high WHR) - Blood pressure 140/90 mmHg or higher - Have a family

People who have trouble with impaired fasting glucose or impaired glucose tolerance - Having high rate of cholesterol or triglycerides - Less physical activities Besides that, people also record other factors such as: high rate of beer consumption or smoking are also be the causes of diabetes 1.2 Intervention model to prevent diabetes The Resolution 42.36 of WHA has introduced a development of Diabetes Prevention Program within national level, engagement of countries to prevent diabetes United Nations (2006) published the Resolution UN61/225 on the prevention of diabetes with the message: Developing policies to treat, prevent and taking care of diabetes International Diabetes Foundation (IDF) has designed a national diabetes prevention program which focuses on enhancing the awareness of community through communication and education Level-1 prevention is to reduce the prevalence of diabetes It is also to change the behaviors and to have early detection of the disease to reduce complications, fatality and enhance the quality of life for people In Viet Nam, Ministry of Health has developed some programs for preventing some infected diseases in the period of 2010-2020 with the purpose to reduce the prevalence and death of diabetes With the following activities: Organizing communication to change behaviors: to propaganda to enhance the awareness of people about the risk of diabetes to prevent Specifically, it is to change bad behaviors, help people to know how to prevent and detect diabetes Therefore, they can avoid complication Organizing evaluation in the community: Previous studies affirmed that diabetes can be managed and prevented We have intervened to prevent diabetes for Khmer at medical station by method as follows: Change our diet: it is recommended to change our habit to reduce the disorder of blood lipids including the decrease of fat, cholesterol, the increase of protein with low fat, fiber To reinforce physical activities: doing exercise regularly can prevent Type diabetes because exercising help reducing the resistance of insulin It is also easy to transform glucose to reduce plasma glucose A scientific Exercising can fresh our mind,

station in diabetes prevention for Khmer” - Interventional actions It includes activities for intervention, prevention of pre-diabetes and diabetes as follows: (1) develop resources and network at medical station which is under the interventional model; (2) Educating community health through communication; (3) consulting to change behaviors; (4) doing exercises; to monitor for early detection and to manage the work of examining and treating at commune medical station (5) - To evaluate the efficiency of intervention model Efficiency index (CSHQ) │p1 – p2│ CSHQ (%)= x 100 │p1│ p1 is the rate
