Đề tài nghiên cứu khoa học: Thiếu máu ở trẻ em Trường Tiểu học của hai xã vùng cao huyện Nam Đông, tỉnh Thừa Thiên HuếJOURNAL OF SCIENCE, Hue University, N0 61, 2010 ANEMIA IN PRIMARY SCHOOL-CHILDREN OF TWO HIGHLAND COMMUNES IN NAM DONG DISTRICT, THUA THIEN HUE PROVINCE Dang Thij Anh Thu, Hoang Trong Sy, Nguyen Van Hoa College of Medicine and Pharmacy, Hue University SUMMARY A survey carried out in 2007 of 336 highland school children in Nam Dong district,Thua Thien Hue Province showed that the total rate of anemia was 28.9%, in which it wasalmost all at mild level (26.2%) and moderate level (2.7%), there were no cases at the seriouslevel; The malnutrition rate of children was 39%. According to the stool tests, the rate ofchildren getting hookworm was the highest with 18.2%. There was a significant differencebetween anemia and ethnic groups (the anemia rate of the Kinh children was lower than that ofthe Catu ones). Moreover, there were other significant differences between anemia andbiological factors, including: age, nutritional status, and hookworm infection. Factors relatingto anemia were geography, household economic levels, the number of days eating meat and fisha week, having parents working as farmers, educational levels of mothers and mother’s practicein feeding children.1. Introduction In recent decades, although there has been a considerable change of socio-economic conditions, anemia is still an important health issue in many rural andhighland areas in Vietnam. Particularly for school-age children, it is dangerous, and notonly related to their physical and mental health but also affects the long-termdevelopment of the community. Thuong Nhat commune and Khe Tre town are two poorhighland areas of Nam Dong district. Basically, people in both areas have a loweducation level, poor income, traditional customs and habits, topography and so on,which restricts living environment, hygienic conditions, and children’s health. Therefore,objectives of this study are to Determine the rate of anemia of primary school childrenin Thuong Nhat commune and Khe Tre Town of Nam Dong district, Thua Thien Hueprovince, compare this rate of the Katu ethnic group to the Kinh and Find out therelationships between anemia and some factors on this group. 4492. Methodology 2.1. Participants The study was conducted in primary schools of Thuong Nhat commune and KheTre town of Nam Dong district, Thua Thien Hue province. 336 pupils randomly selectedby EPI INFO statistical software were evaluated, included 164 pupils of Thuong Nhatcommune primary school and 172 Khe Tre Town primary pupils. The study wasconducted from June to September, 2007. 2.2. Research method This was a cross-sectional survey. Children’s weight and height was measured to examine the nutritional condition. Blood samples were collected for the measurement of hemoglobin concentration,using the KX-21 machine (Symex, Japan). Formalin ether technique was used to test stool samples to look for helmintheseggs. Mothers of those children were directly interviewed for more informationrelating to anemia, the answers were written down using questionnaires. Assessment indicators - Evaluating children’s anemia status based on the hemoglobin concentrationstandard (g/dl) of the World Health Organization (Mild anemia: 9.0-11.9g/dl, moderateanemia: 7-8.9g/dl, serious anemia: lower than 7g/dl). - Evaluating helminthes infection status by whether children had helmintheseggs (including Hookworm’s, Ascaris’or Trichuris’s eggs) in stool samples or not. - Weight and height were used for evaluating nutrition condition of children (Ifthe children are younger than 9 years old, the index of weights over heights based on theconferential population was calculated: - Lower than -2SD was considered malnutrition - Equal to or over -2SD was considered normal For 9 year old children and the older, whose height was over the upperboundary’s height, a BMI indicator was applied. Weight BMI = Height2 Assessment: under 5th centigrade of the conferential population was consideredmalnutrition, equal and over 5th centigrade of conferential population was considered 450normal. - Some other factors were also evaluated, including: children’s infectious statusas well as blood lost status in the six weeks before the study was conducted, householdeconomic levels, the number of days eating meat and fish a week, having parentsworking as farmers, educational levels of mothers and mother’s practices regardingfeeding children.
