| [Background] Iron deficiency anemia(IDA) is a world-wide nutritional disease in children and it is also in the first place of "the four diseases" which the Chinese government are focus on prevention and control diseases among children, The peak age is 6 to 24 months. The harm of IDA in early childhood is extremely serious. Although over the years the government has taken various measures to control IDA, However, in poor rural areas, especially in the western region anemia remained high in children. Epidemiological factors of children's IDA are complicated and changeable. Therefore, exploring its epidemiological factors, has significant meaning for the prevention of children's IDA.[Objective] To investigate the anemia status and its influencing factors of infants aged 6-24 months in Guangxi and Inner Mongolia rural areas.[Methods] Using stratified random cluster sampling method to investigate a total of 2677 infants aged 6～24 months fromLingshan countiy,Binyang countiy and Heng countiy of Guangxi and Muolidawa countiy,Elunchun countiy,Arong countiy and Zhalantun countiy of Inner Mongolia rural areas. We had anthropometric measurements and hemoglobin determination to 6～24 months old infant; their carers questionnaires. According to hemoglobin test results, the survey will be divided into anemic infants with and without anemia group. EPi data 3.0 software was employed to establish a database, and make double entry verification. SPSS 15.0 was used to analyze the factors related to IDA. Measurement data with the mean, standard deviation description; count data-rate, frequency description Chi-square and mutivariant logistic regression were used to find out all factors in this study.[Results] The prevalence of anemia among infants aged 6～24 months was 51.3% in Guangxi and Inner Mongolia rural areas. The prevalence of low-grade anemia was 80.3%; the prevalence of mid-and high-grade anemia was 19.7%. IDA prevalence rate among boys was 52.7%, which was higher than the girls (49.6%). No statistical difference was found (P>0.05). IDA prevalence rate among children in Guangxi was 57.8% which is significantly higher than Inner Mongolia (45.1%). The rate of anemia was the most high at 6～11 months and it decreased with the increasing of age. The rate of anemia was 36.3% at 18～24 months. There were statistical difference (P<0.01) between different months groups. Multivariate logistic regression analysis showed that children wasting (OR=3.202,95% CI=1.094～9.367) and complementing grain before 4 month (OR=1.864,95% CI=1.294～2.685) was the risk factor related to infants anemia while the frequency of complementing milk (OR=0.823,95% CI=0.722～0.939) mother's high education (OR=0.725,95% CI=0.534～0.983) and the frequency of educating (OR=0.855,95% CI=0.773～0.946) were the positive factors.[Conclusions] The prevalence of anemia among infants aged 6～24 months in Guangxi and Inner Mongolia rural areas is high and corresponding measures should be taken to prevent and control infants anemia. |
