【摘要】：目的分析重庆城区中小学生月经初潮及首次遗精年龄与其父母生育年龄的相关性,为儿童青少年青春早期发育研究和健康教育提供理论依据。方法采用多阶段分层整群随机抽样方法,调查重庆主城2个区7 285名中小学生(男生3 649名,女生3 636名)的月经初潮、首次遗精年龄及其父母生育年龄。采用描述统计分析、t检验、多重线性回归等方法进行统计分析。结果重庆城区男生首次遗精的平均年龄为13.14岁,乡村男生比城镇男生早0.2岁(t=-3.016,P=0.003);女生月经初潮的平均年龄为12.43岁,城乡差异无统计学意义(t=-0.506,P=0.613)。母亲生育年龄对其子女月经初潮、首次遗精年龄影响无统计学意义(P值均0.05);父亲生育年龄每增加1岁,其女儿月经初潮提前0.034岁(乡村提前0.019岁,P=0.024;城镇提前0.048岁,P0.01),儿子首次遗精年龄提前0.025岁(乡村提前0.013岁,P=0.818;城镇提前0.029岁,P=0.027)。结论父亲生育年龄较大可能是其子女首次遗精、月经初潮年龄提前的影响因素之一。减少大龄产父母可降低其对儿童青少年生长发育的不良影响。
[Abstract]:Objective to analyze the correlation between the age of menarche and the age of first spermatozoa and their parents' reproductive age in primary and middle school students in Chongqing city, and to provide theoretical basis for the study of adolescent youth early development and health education.Methods A multi-stage stratified cluster random sampling method was used to investigate the menarche, the age of first spermatozoa and the reproductive age of their parents among 7 285 primary and middle school students (3 649 male and 3 636 female) in two main districts of Chongqing.Descriptive statistical analysis and multiple linear regression are used for statistical analysis.Results the average age of the first spermatozoa of boys in Chongqing was 13.14 years old. The average age of menarche of girls was 12.43 years old, and the average age of menarche of girls was 12.43 years. There was no significant difference between urban and rural areas.There was no significant difference between the age of first spermatozoa and the age of menarche and the age of first spermatozoa (P = 0.05), but the age of father's childbearing increased by 1 year.His daughter's menarche was 0.034 years old (0.019 years old in rural area, 0.048 years old in town, 0.025 years old in son's first spermatozoa, 0.013 years earlier in rural area and 0.029 years earlier in town).Conclusion the older paternal age may be one of the factors affecting the first spermatozoa and the early menarche age of their children.Reduction of older parents can reduce their negative effects on the growth and development of children and adolescents.
