1Department of Epidemiology and Biostatistics, School of Public Health, Peking University Health Science Center, Beijing 100191, China Key Laboratory of Epidemiology of Major Diseases (Peking University), Ministry of Education, Beijing 100191, China.
这项研究表明,遗传因素显著影响中国成年人的吸烟行为,在男性和特定的人口统计学方面观察到的比例更高. 遗传概率的估计表明,吸烟习惯有一个重要的遗传成分.
科学领域:
- 行为遗传学 行为遗传学
- 流行病学 流行病学
- 双胞胎研究 双胞胎研究
背景情况:
- 吸烟行为在全球范围内带来了重大的公共卫生挑战.
- 了解遗传和环境因素的相互作用对于有效的戒烟干预至关重要.
研究的目的:
- 调查中国双胞胎登记 (CNTR) 中成年双胞胎吸烟行为的人口和区域分布.
- 确定单胞胎 (MZ) 和双胞胎 (DZ) 双胞胎吸烟行为的一致率.
- 为了估计吸烟行为的遗传性.
主要方法:
- 利用随机效应回归模型分析吸烟行为在子组中的分布.
- 计算了MZ和DZ双胞胎之间的吸烟行为对应率.
- 估计吸烟行为的遗传性使用CNTR中28444对双胞胎的数据.
主要成果:
- 目前吸烟的患病率是男性的41.2%和女性的1.2%.
- 在老年男性,北部地区,农村地区,离婚者/寡妇以及初生双胞胎中,吸烟率较高.
- 吸烟一致性在男性MZ双胞胎 (69.6%) 比DZ双胞胎 (57.3%) 高,男性估计遗传率为28.9%.
结论:
- 双胞胎登记册中的吸烟行为模式反映了一般人口的趋势,但显示了独特的特征,比如第一胎双胞胎的更高率.
- 遗传因素在吸烟行为中起着重要作用,遗传性因地区和年龄而异.
- 这些发现支持了遗传影响对吸烟行为的重要性,为有针对性的公共卫生战略提供了信息.
