The purpose of this paper is to assess the effectiveness of school-based intervention aimed to increase knowledge, to change attitudes and to reduce smoking-related behavior in both Linzhi Tibetan and Guangzhou Han middle school students in China.
A concurrent intervention study was conducted in both Linzhi and Guangzhou. Two schools were randomly chosen and one was randomly assigned to the intervention group and the other to the control group in both settings.
SETTING/PARTICIPANTS: Participants were grade one and grade two middle school students drawn from two schools in Linzhi, Tibet Autonomous Region (southwest China) and two schools in Guangzhou, Guangdong Province (south China).
The intervention program lasted for one year and covered three aspects: health policies in school, health environment in school and personal health skills.
Primary outcomes were smoking-related knowledge, attitudes and behavior (including ever smoking, daily smoking, weekly smoking and current smoking) and were measured by a self-administered questionnaire before and after the intervention.
This intervention increased smoking-related knowledge in both Tibetan (β=1.32, 95% CI (0.87-1.77)) and Han ethnic groups (β=0.47, 95% CI (0.11-0.83)). It changed attitudes toward smoking in Tibetan (β=1.47, 95% CI (0.06-2.87)) but not so in Han (β=-0.33, 95% CI (-1.68-1.01)). The intervention changed the prevalence of smoking in neither ethnic groups (P>0.05).
The impact of school-based smoking intervention is different among Tibetan and Han students. This intervention was more effective for Tibetans when compared with the Han ethnic group. More research is needed on how intervention can be adapted to address ethnic and cultural differences.
本研究旨在评估以提高知识、改变态度和减少与吸烟相关行为为目标的学校干预措施在中国林芝藏族和广州汉族中学生中的有效性。
在林芝和广州同时进行了一项干预性研究。在两个地区各随机选择了两所学校，一所被随机分配到干预组，另一所被分配到对照组。
地点/参与者：参与者来自西藏林芝地区（中国西南）和广东省广州市（中国南部）的两所学校的一年级和二年级中学生。
干预方案持续了一年，涵盖了三个方面：学校的健康政策、学校的健康环境和个人健康技能。
主要结果是与吸烟相关的知识、态度和行为（包括曾经吸烟、每日吸烟、每周吸烟和当前吸烟），在干预前后通过自我管理问卷进行测量。
这种干预措施增加了藏族（β=1.32，95%可信区间（0.87-1.77））和汉族（β=0.47，95%可信区间（0.11-0.83））学生与吸烟相关的知识。它改变了藏族学生对吸烟的态度（β=1.47，95%可信区间（0.06-2.87）），但对汉族学生没有影响（β=-0.33，95%可信区间（-1.68-1.01））。干预对两个民族的吸烟流行率都没有影响（P>0.05）。
学校为基础的吸烟干预对藏族和汉族学生的影响不同。与汉族学生相比，这种干预对藏族学生更为有效。需要进一步研究如何调整干预措施以解决民族和文化差异。
