To investigate the prevalence and influencing factors of anemia children aged 0-6 years in Shannan city, Xizang Autonomous Region. A cross-sectional study was performed to measure hemoglobin of 12 405 children aged 0-6 years in 12 counties (districts) of Shannan city, Xizang Autonomous Region and basic information including gender, age, ethnicity, address, local altitude, urban area, agricultural and pastoral areas, etc were collected. According to the altitude of the surveyed children's place of residence, anemia in children under the plain standard and the prevalence of anemia after adjusting for altitude were reported, and the influencing factors of anemia in these children were analyzed by Logistic regression methods. Among the 12 405 children, 6 383 (51.46%) were males, 6 022 (48.54%) were females, 462 (3.72%) were newborns, 68 (0.55%) were 1 month old children, 153 (1.23%) were 4-<6 months old children, and 11 722 (94.49%) were 6 months to 6 years old children. The prevalence of anemia in children aged 0-6 years in Shannan city before altitude correction was 15.50%(1 923/12 405), and it was 57.84% (7 175/12 405) after altitude correction. The hemoglobin level in the children was (131±20) g/L. Univariate analysis showed that the anemia rate of males was higher than that of females (59.17% (3 777/6 383) 56.43% (3 398/6 022), <0.05), the anemia rate of Tibetan children was higher than that of children of other ethnic groups (58.21% (6 992/12 011) 46.45% (183/394), <0.05), the anemia rate of children in agricultural and pastoral areas was higher than that of urban children (58.75% (6 212/10 574) .(52.59% 963/1 831), <0.05), and the anemia rate of children in higher-altitude areas was higher than that of children in high-altitude areas (67.98% (2 773/4 079) .52.87% (4 402/8 326), <0.05). Logistic regression analysis revealed that girls (=0.89, 95% 0.83-0.96), children of other ethnic groups (=0.72, 95% 0.58-0.89), children aged 4-<6 months (=0.40, 95% 0.24-0.67) and children aged 6 months to 6 years (=0.59, 95% 0.43-0.82) were protective factors, and children who lived in agricultural and pastoral areas (=1.15, 95% 1.04-1.28) and children living at altitudes higher than 4 000 m areas (=1.88, 95% 1.73-2.04) were independent risk factors for the occurrence of anemia. The prevalence of anemia in children aged 0-6 years in Shannan city was still relatively high. It might be affected by factors such as sex, ethnicity, age of the children, place of residence and altitude where the children lived.
为调查西藏自治区山南市0-6岁儿童贫血的患病率及影响因素。对西藏自治区山南市12个县（区）的12405名0-6岁儿童进行横断面研究，测量其血红蛋白，并收集性别、年龄、民族、住址、当地海拔、城区、农牧区等基本信息。根据被调查儿童居住地海拔，报告平原标准下儿童贫血情况及海拔校正后贫血患病率，并采用Logistic回归方法分析这些儿童贫血的影响因素。在12405名儿童中，男性6383名（51.46%），女性6022名（48.54%）；新生儿462名（3.72%），1月龄儿童68名（0.55%），4-<6月龄儿童153名（1.23%），6月龄至6岁儿童11722名（94.49%）。山南市0-6岁儿童海拔校正前贫血患病率为15.50%（1923/12405），海拔校正后为57.84%（7175/12405）。儿童血红蛋白水平为（131±20）g/L。单因素分析显示，男性贫血率高于女性（59.17%（3777/6383）对56.43%（3398/6022），<0.05），藏族儿童贫血率高于其他民族儿童（58.21%（6992/12011）对46.45%（183/394），<0.05），农牧区儿童贫血率高于城区儿童（58.75%（6212/10574）对52.59%（963/1831），<0.05），高海拔地区儿童贫血率高于低海拔地区儿童（67.98%（2773/4079）对52.87%（4402/8326），<0.05）。Logistic回归分析显示，女孩（β=0.89，95%CI 0.83-0.96）、其他民族儿童（β=0.72，95%CI 0.58-0.89）、4-<6月龄儿童（β=0.40，95%CI 0.24-0.67）和6月龄至6岁儿童（β=0.
