大气污染对儿童特别是低年龄儿童的健康造成严重危险。工业企业排放区内儿童呼吸道疾患的就诊率比大气无污染地区高一倍,且发育迟缓,尤其是婴儿(74%)。然而此类研究,特别是对婴儿死亡率的研究极少。本文进行了这方面的探讨。作者分析了某些社会卫生学、生物学因素(包括大气污染)对婴儿死亡率的影响程度。选出下述研究因素:小儿性别、母亲教育水平、母亲社会地位、喂养特点、人口平均收入、胎次、本次孕前流产数、母亲分娩时年龄、居住条件。设观察区和对照区。两区气候地理条件,社会-卫生学指标和医疗服务水平均近似, Air pollution poses a serious risk to the health of children, especially those of lower ages. The prevalence of child respiratory disease in industrial enterprises’ discharge zones is twice as high as that in the non-polluting areas of the atmosphere and is slow to develop, especially in infants (74%). However, there is very little research on such studies, especially on infant mortality. This article has carried on the discussion in this respect. The authors analyzed the impact of certain social hygiene, biological factors (including air pollution) on infant mortality. The following research factors were selected: pediatric sex, mother’s educational level, mother’s social status, feeding characteristics, population average income, parity, abortion number before pregnancy, mother’s age at delivery, living conditions. Set observation and control area. The climatic and geography conditions, social-hygiene indicators and medical service levels of the two districts are similar,
