Background: Rate of anemia is quite high in hospitals. This condition occurs in all age groups, genders, occupations and all areas of the country. The assessment of the situation, degree, nature as well as classification of anemia is necessary for the diagnosis, treatment and prognosis. Objectives: To study the features of anemia on the patients treated in Thai Binh General hospital. Subjects and methods: the analytic descriptive study was carried out on 3522 cases who were treated in Thaibinh General hospital from May 1st, 2004 to April 30th, 2005. Results: The percentage of the anemic patients was 14.16% of the total patients in Thaibinh General hospital. The rate of the anemia of children was 57.61 % and the elderly was 19% of all anemic patients. The rate of mild anemia was 64.2% and the sever anemia was 14.9%. The rate of chronic anemia was 72.9%. The microcytic anemia was 45.94%, the macrocytic anemia was 0.57%. The anemia in the blood diseases and hematopoietic diseases were 8.38% including thrombocytopenic purpura, thalassemia, leukemia, aplastic anemia and hemophilia. Conclusions: The rate of patients with anemia in Thai Binh General Hospital in period of 2004 - 2005 was 14.16% in the total patients treated; among them the rate of anemia in children was high.

Study was carried out in 323 bottle-fed infants od 5-6 months old in Dong Hy District – Thai Nguyen province in 2002 year. Malnourhished occurred in a high incidence, 11.5% have had a substandard height, 74.6% anemia and 39.3% vitamin A deficiency. Anemia and vitamin A deficiency were correlated positively. Anemia infants have had 2.3 times higher of vitamin A deficiency than normal infants and in contrary. Ethnic minority infants have had a gap rate of anemia and vitamin A deficiency 2 times higher than Kinh infants. In mothers, knowledge and practice of nutrition and breastfeeding, and of infant care were very limited. Nutrition supplements was not appropriate

BACKGROUND: To evaluate the accuracy of a portable hemoglobin photometer, the HemoCue, during surgery, hemoglobin concentrations (Hb) of HemoCue were compared with those of the SYSMEX XE-2100, in the situation of bleeding. METHODS: Hemoglobin concentrations were measured with HemoCue and by the SYSMEX XE-2100 at the same time, on 100 blood samples obtained from patients who were bleeding more than 500 ml, during surgery. The limits of agreement between the two methods were calculated from the results according to the method of Bland & Altman. The results of HemoCue were adjusted by adding the mean bias, defining the corrected values, and reevaluated the agreement with the results of the SYSMEX XE-2100. RESULTS: The differences in results between the two methods were 1.12 +/- 0.37 g/dl. The limits of agreement were 0.38-1.86 g/dl, which means disagreement between the two methods. However, the corrected values represented agreement with the values of the SYSMEX XE-2100. The limits of agreement were -0.74-0.74 g/dl. CONCLUSIONS: The corrected Hb values of HemoCue were comparable to the values of SYSMEX XE-2100. It is useful to evaluate the hemoglobin concentration using HemoCue intraoperatively.

BACKGROUND: Tuberculosis is a major public health problem caused by Mycobacterium tuberculosis, occurring predominantly in population with low socioeconomic status. It is the second most common cause of death from infectious diseases. Tuberculosis becomes a double burden among anemic patients. Anemia increases an individual's susceptibility to infectious diseases including tuberculosis by reducing the immunity level. Therefore, the purpose of this study was to determine whether anemia is a risk factor for tuberculosis. METHOD: Relevant published articles were searched in electronic databases like PubMed, Google Scholar, EMBASE, and Cochrane Library using the following MeSH terms: risk factor, predictors, tuberculosis, TB, Anaemia, Anemia, hemoglobin, Hgb, and Hb. Articles written in the English, observational studies conducted on the incidence/prevalence of tuberculosis among anemic patients, or papers examined anemia as risk factors for tuberculosis were included. From those studies meeting eligibility criteria, the first author's name, publication year, study area, sample size and age of participants, study design, and effect measure of anemia for tuberculosis were extracted. The data were entered using Microsoft Excel and exported to Stata version 11 for analysis. The random-effects model was applied to estimate the pooled OR and HR, and 95% CI. The sources of heterogeneity were tested by Cochrane I-squared statistics. The publication bias was assessed using Egger's test statistics. RESULTS: A total of 17 articles with a 215,294 study participants were included in the analysis. The odd of tuberculosis among anemic patients was 3.56 (95% CI 2.53-5.01) times higher than non-anemic patients. The cohort studies showed that the HR of tuberculosis was 2.01 (95% CI 1.70-2.37) times higher among anemic patients than non-anemic patients. The hazard of tuberculosis also increased with anemia severity (HR 1.37 (95% CI 0.92-2.05), 2.08 (95% CI 1.14-3.79), and 2.66 (95% CI 1.71-4.13) for mild, moderate, and severe anemia, respectively). CONCLUSION According to the current systematic review and meta-analysis, we can conclude that anemia was a risk factor for tuberculosis. Therefore, anemia screening, early diagnose, and treatment should be provoked in the community to reduce the burden of tuberculosis.

A cross-sectional surveys on 1.206 children aged < 13 years old were carried out in Tra Mai commune of Quang Nam province and Phu Rieng commune of Binh Phuoc province in 2 years of 1999 and 2000. The proportion of anaemia children in Tra Mai was 21.6%, Phu Rieng was 33.5%. The most of them were mild anaemia patients. No severe anaemia case was detected. Malaria, hookworm were determined to be the risk factors for anaemia. There was a correlation between the hemoglobin concentration, the malaria parasitemia and the intensity of hookworm infection. Acid folic supplement treatment with dose of 2mg/kg/day x 30 days, combined with specific drugs in anaemia children had increased clearly hemoglobin concentration compared with single specific drugs

OBJECTIVETo describe the prevalence of anemia and yearly trends (1993-2003) among women who came to the hospitals or maternal and child health units for premarital examinations in 6 counties of Jiangsu and Zhejiang provinces.

METHODSData were obtained from the records of the premarital examinations in perinatal health care surveillance system that had been established since 1992 in these areas. We reviewed hemoglobin levels of those women who were enrolled in the perinatal health care surveillance system from 1993 to 2003. Anemia was defined according to the WHO (2001) criterion. We calculated the prevalence of anemia and analyzed the yearly trends based on the data of hemoglobin concentration.

RESULTSIn the period of 1993-2003, there were 82 995 anemia cases identified among 193,434 women with an overall anemia rate as 42.9%. The rates of anemia were high (65.5%) in 1993 but low (25.8%) in 2003. 99.7% of the anemic women whose hemoglobin concentration were between 80-119.9 g/L. Time trend analysis indicated a significant decline on anemia rate while monthly analysis showed that the prevalence rates were high (48.2%) in September and low in March (39.5%). The results also showed that the prevalence rates of anemia were relatively higher in farmers and workers in rural enterprises, and lower in Han ethnicity than minorities. The higher prevalence rates of anemia were presented among the women with less education, lower body mass index, or at older age.

CONCLUSIONFor those premarital women in 6 counties of Jiangsu and Zhejiang provinces, the overall anemic rate presented a significant downward trend between 1993 and 2003 while the prevalence of anemia remained high, especially for the women with less education, lower body mass index or older ages.

Objective: To analyze anemia prevalence and its influencing factors of students involved in the Nutritional Improvement Program for Rural Compulsory Education Students in 2019. Methods: From the 2019 surveillance system of the Nutrition Improvement Program for Rural Compulsory Education Students, 47 297 primary and middle school students aged 6-17 were included in the study. Hemoglobin level was tested according to the criteria of WHO 2011. Anemia prevalence of different genders, ages, and regions was analyzed. Results: The average hemoglobin level was 135.19 g/L, with the prevalence of anemia as 8.7% in the children aged 6-17. The prevalence of anemia was 10.0% in girls, higher than that in boys (7.4%). The prevalence rates in western and central areas were 9.8% and 7.1%, respectively. From northwest, southwest, central and south, east, north to northeast areas of China, the anemia rate appeared gradually decreasing (10.2%, 9.7%, 8.3%, 7.5%, 5.7% and 3.5%). The anemia prevalence rates were 8.0%, 8.3%, and 10.9% in children from the 6-, 11-, and 14-17 years age groups, respectively. Logistic regression models revealed that students from schools not using catering software (OR=1.482, 95%CI:1.296-1.694,P<0.001), schools not serving lunch (OR=1.241, 95%CI:1.103-1.395,P<0.001), and from relatively low-income families (OR=1.297, 95%CI:1.211-1.389, P<0.001) showed as risk factors for anemia. After supplementing students' dietary factors, the results showed that students who ate meat three or more times a week had a lower risk of anemia (OR=0.907, 95%CI:0.832-0.989, P=0.026). Conclusions: The Nutritional Improvement Program for Rural Compulsory Education Students had an essential impact on improving the anemia prevalence of primary and middle school students. Family income, school location, economic factors, school feeding, and students' diet programs all impacted the prevalence of anemia.
