目的 了解本地区儿童血铅水平及相关影响因素,为制订相关公共卫生政策提供依据。方法 抽取2个城区,共计3所不同等级幼儿园共2 510例0～7岁儿童进行监测和问卷调查。用钨舟原子吸收光谱分析仪检测血铅水平。结果 高铅血症的检出率为7.8%。0～2岁组高血铅检出率明显高于5岁以上组(P＜0.05)。多因素回归分析显示父亲文化程度越低,儿童高血铅检出率越高,差异有统计学意义(P＜0.01)。装修距今时间越短、玩具清洗频率越低及啃手指甲与其对照组相比,均是高铅血症的危险因素(P均＜0.05)。结论 环境干预结合健康教育,培养儿童养成良好的生活行为习惯是预防儿童高铅血症的重要手段。
Abstract
Objective To investigate children's blood lead level and its influencing factors in Lanzhou,and to provide evidence for public health policies. Methods Totally 2 510 children aged 0~7 from three kindergartens of two districts in Lanzhou were enrolled to test blood lead level and to finish questionnaires.Tungsten boat atomic absorption spectrometry was used to test blood lead levels. Results The detection rate of high blood lead was 7.8%.The detection rate of high blood lead in children under two years old was higher than that in children over 5 years old (P<0.05).Multivariate regression analysis showed the lower education level of father,indicated higher rate of high blood lead in children (P<0.01).Recent home decoration,lower toys cleaning frequency and gnawing fingernails were risk factors of high blood lead (P<0.05). Conclusion Environmental intervention combined with health education and developing good daily behavior habits are important Methodsof preventing high blood lead in chilren.
