Objective To study the effects of adolescent sexual development on the smoking behavior of adolescents. Methods In November 2000, a cross-sectional questionnaire survey was conducted on 14 5 3 high school students in Shanghai collected from a randomized cluster. The questionnaires were used to get the data of juvenile smoking, age of first spermatorrhea, age of girl’s menarche and psychosocial factors that may affect teenagers’ smoking And other information. Results The prevalence of smoking among male students was highest (2. 8.6%) in the late sexual development group, followed by the earlier (21.3%) and the middle group (2.17%). The current smoking rate was the highest in the sexual development group 16.4%), followed by the late development (7.1%) and the middle group (4.8%). The former smoking rate of girls was 24.2% in the early, middle and late stages of sexual development. 0%, 6 .3%. After controlling for a series of psychosocial factors affecting teenagers’ smoking, sexual development earlier was the independent risk factor for boys smoking now (OR = 3.6 8, 95% CI: 1.2 3 ~ 10.99), and was also a risk factor for smoking among girls (OR = 2.2 3,95% CI: 0.89-5.60). Late development of children may lead to male smoking (OR = 1.4 8,95% CI: 0.72-3.06) It may have some protective effect on girls (OR = 0.664, 95% CI: 0.222 ~ 1.86). Conclusion Schools, families and the community should be concerned about, guide the deviations of normal development of sexual time between young people and adolescents, strengthen the health hazards of smoking health education
