【摘要】 本文抽样调查2319名普通中学学生,吸烟率18.4％,男性吸烟率35.3％,女性吸烟率0.9％。吸烟率随年级增高而增加。以13～17岁开始吸烟最多,占吸烟总数的77.15％,16～18岁(初三～高二)吸烟率每年(岁)递增10％,所以13～15岁(初一、二)是有效控制吸烟的“最佳年龄”;最早开始吸烟年龄为6岁,10岁开始增多,因此禁烟教育应从小学抓起;青少年吸烟主要与社会气候、家庭和朋友影响有关;吸烟可使体内SCN~-、CO、COHb含量增加,吸烟年限,吸烟量与体内SCN~-含量呈正相关。吸烟量与唾液ML含量呈负相关。更多还原

It showed the increase with increasing of the grade. Most of them was from 13 to 17 years old, which made up 77.15 percent of all.
