计划生育是我国的第一国策。要提高我国人口素质,必须从胎儿期做起,年轻的夫妇谁不想生一个健壮的娃娃呢?而如何使我们的孩子健壮,如何优生优育却不一定为每个年轻人所知。十月怀胎,孩子哇哇坠地,是喜是忧须从结婚、怀孕谈起:一对晚婚晚育的新婚夫妇,只要双方没有生理缺陷,婚后怀孕便指日可待了,我国生育虽有自然的相对高峰期,而怀孕却并没有季节性,四季都可结婚,季季均能怀孕,而从优生优育的角度来说,早期妊娠(3个月内)应避免在冬、春季节,为此而选择新婚佳期是必要的。若早孕发生在空气污染较重的冬季,胎儿是缺陷儿的相对危险性明显高于其他季节。根据我国36个单位协作参加的我国“七五”重点攻关课题《环境质量与出生缺陷(BD)关系流行病学研究》表明,室内外空气污染与早孕胚胎致畸显著相关。冬季大气二氧化硫(SO_2)、总悬浮颗粒(TSP)浓度最高,出生缺陷率为7.9‰,夏秋季节浓度最低,出生缺陷率为5—5.8‰。尤其在空气污染较重的工业城市更应注意。冬季取暖、家庭生活用燃料对出生
Family planning is our country’s first national policy. To improve the quality of our population, we must start from the fetus, young couples who do not want to give birth to a robust doll? How to make our children robust, but not necessarily for each young people known. October pregnancy, children wow fall, joy is the worry from the marriage, pregnancy talk about: a late marriage and childbirth of newlyweds, as long as the two sides have no physical defects, married pregnancy will be just around the corner, although the birth of our natural relative peak period , But pregnancy is not seasonal, the four seasons can be married, the season can be pregnant, but from the perspective of prenatal and postnatal care, early pregnancy (3 months) should be avoided in the winter, spring, choose the wedding Good times are necessary. If early pregnancy occurred in the heavier air pollution in winter, the relative risk of fetus is defective children was significantly higher than the other seasons. According to the epidemiological study on the relationship between environmental quality and birth defects (BD), the key research topic of “75” in our country, which participated in by 36 units of China, showed that indoor air pollution and teratogenicity of early pregnancy were significantly related. The concentration of sulfur dioxide (SO 2) and total suspended particulates (TSP) in winter was the highest, with a birth defect rate of 7.9 ‰, the lowest concentration in summer and autumn, and the birth defect rate of 5-5.8 ‰. In particular, heavier air pollution in industrial cities should pay more attention. Winter heating, family life with fuel on the birth
