目的:探讨百日咳患儿在流行季节的易感因素。方法:通过对我院2007年1月至2011年12月5年收治的148例患儿进行流行季节易感因素分析,发现缺铁性贫血是百日咳患儿的易感因素。结果:在本组148例百日咳患儿中,有126例患儿有不同程度的缺铁性贫血(血色素正常范围为116-126g/L,患儿血色素<116g/L诊断为缺铁性贫血),占全部患儿的85.2%。结论:婴幼儿在基线特征相同的情况下患有缺铁性贫血(营养不良性),较正常儿童易并发百日咳,两者的发生有一定的关系,故缺铁性贫血是百日咳患儿的易感因素。预防缺铁性贫血的发生可以有效预防百日咳,因此,在流行季节需加强婴幼儿营养,增加其免疫力,以防缺铁性贫血的发生。
Objective: To investigate the susceptibility factors of children with pertussis during the epidemic season. Methods: According to the seasonal epidemiological analysis of 148 children admitted from January 2007 to December 2011 in our hospital, iron deficiency anemia was found to be a predisposing factor for whooping cough. Results: Among the 148 children with pertussis in this study, 126 children had different degrees of iron deficiency anemia (normal range of hemoglobin was 116-126g / L, children with hemoglobin <116g / L were diagnosed as iron deficiency anemia) , Accounting for 85.2% of all children. CONCLUSIONS: Infants and young children have iron deficiency anemia (malnutrition) at baseline characteristics and are more likely to develop pertussis than normal children, and the relationship between the two is correlated with each other. Therefore, iron deficiency anemia is a predilection for children with whooping cough Feeling factors. To prevent the occurrence of iron deficiency anemia can effectively prevent whooping cough, therefore, in the popular season to strengthen infant nutrition, increase their immunity, to prevent the occurrence of iron deficiency anemia.
