目的:了解雅安地区0~12岁儿童血铅水平及其影响因素,为有效干预提供依据。方法:用原子吸收光谱法对703例2月~12岁儿童末梢血进行血铅含量测定,并对高铅血症进行相关因素分析。结果:703例儿童血铅均值为71.96±22.31μg/L,其中高铅血症有57例,占8.1%,年龄越大,血铅含量越高(P<0.05),且男童高于女童(P<0.05)。结论:该地区的血铅水平与其他国内城市相比偏低,儿童血铅的含量与自身的卫生饮食习惯及所处环境有关,要加强儿童保健及父母的健康教育。 Objective: To understand the blood lead levels and its influencing factors in children aged 0 ~ 12 years in Ya’an and provide the basis for effective intervention. Methods: The blood lead levels in 703 children aged 12 months to 12 years were measured by atomic absorption spectrometry, and related factors were analyzed. Results: The mean blood lead of 703 children was 71.96 ± 22.31μg / L, including 57 cases of hyperlipidemia, accounting for 8.1%. The older the age, the higher the content of blood lead (P <0.05) (P <0.05). Conclusion: The level of blood lead in this area is relatively low compared with other cities in China. The level of blood lead in children is related to their own health and eating habits and their environment. Children’s health care and parental health education should be strengthened.
