影响小儿反复呼吸道感染的危险因素研究

摘要

Objective To discuss the risk factors influencing repeated respiratory tract infection in children.Methods 80 children with repeated respiratory tract infection in our hospital from February 2010 to December 2011 were selected as observation group while 80 normal children were selected as the control group.The immune function and levels of trace element in the blood between two groups were compared and analyzed.Results The average concentration of the iron in the blood of the observation group was(12.38 ± 2.76)μ mmol/L,the qualified rate was 48.75％,the concentration of the Calcium was (2.12 ± 0.24)μ mmol/L,the qualified rate was 58.75％;the concentration of zinc was(18.05 ± 11.74)μ mmol/L,the qualified rate was 61.25％.The average concentration of the iron in the blood of the control group was(16.53 ± 3.88)μ mmol/L,the qualified rate was 80％;the concentration of the Calcium was(2.57 ± 0.48)μ mmol/L,the qualified rate was 85％;the concentration of zinc was(29.33 ± 9.78)μmmol/L,the qualified rate was 75％.There were statistical significant differences in the two groups(P＜0.05).Conclusions The lack of the trace element in the blood is one of the risk factors influencing the repeated respiratory tract infection.%目的 探讨分析影响小儿反复呼吸道感染的危险因素.方法 选取我院于2010年2月至2011年12月收治的80例反复呼吸道感染的患儿设为观察组,另选取80例健康的患儿设为对照组,测定2组儿童的免疫功能及血微量元素,进行比较.结果 观察组平均空腹血清铁浓度(12.38±2.76)μmmol/L,合格率48.75％,钙浓度(2.12±0.24)μmmol/L合格率58.75％,锌浓度(18.05±11.74)μmmol/L,合格率61.25％;对照组平均空腹血清铁浓度(16.53±3.88)μmmol/L,合格率80％,钙浓度(2.57±0.48)μmmol/L,合格率85％,锌浓度(29.33±9.78)μmmol/L,合格率75％,两组比较差异有显著性(P＜0.05).结论 血液中的微量元素含量不足是影响小儿反复呼吸道感染的危险因素之一.
