目的:探讨血液中锌元素含量与6～9个月婴儿发育商的相关性。方法:选取门诊208例6～9个月婴儿(其中男婴126例,女婴82例)使用上海复旦大学附属儿科医院监制的《0～6岁儿童智能发育筛查量表》测定发育商(DQ);在测定结束后采集其指尖末梢血,使用火焰原子吸收法测定血液中锌元素含量。结果:共调查婴儿208例,血中锌元素分布为增高0例,正常134例,缺乏74例;发育商为优秀0例,聪明9例,正常137例,偏低58例,低下4例;不同性别之间婴儿的血液中锌元素含量没有显著性差异(χ2=0.12,P>0.05);不同性别之间婴儿的智商没有显著性差异(χ2=0.31,P>0.05);婴儿血中锌元素与发育商的相关性分析显示,r锌=0.410,P<0.01。结论:血中锌元素含量与发育商呈正相关。
Objective: To investigate the correlation between zinc content in blood and infant development in 6 ~ 9 months. Methods: A total of 208 infants aged 6 to 9 months (including 126 male infants and 82 female infants) were enrolled in this study. The “Developmental Scale of Intelligence Development Screening for Children 0-6”, produced by Pediatric Hospital affiliated to Fudan University in Shanghai, DQ). At the end of the measurement, peripheral blood of fingertips was collected, and the content of zinc in blood was determined by flame atomic absorption spectrometry. Results: A total of 208 infants were enrolled in this study. The distribution of zinc in the blood was 0 cases, 134 cases were normal and 74 cases were poor. The developmental providers were excellent 0 cases, clever 9 cases, normal 137 cases, low 58 cases and low 4 cases. There was no significant difference in the levels of zinc in the blood of infants between different genders (χ2 = 0.12, P> 0.05). There was no significant difference in the IQ of infants between different genders (χ2 = 0.31, P> 0.05) Correlation analysis of the elements and the developers showed that r = 0.410, P <0.01. Conclusion: There is a positive correlation between zinc content in blood and developmental providers.
