A smoking prevention program was developed to prepare children in elementary school for secondary school. This study assessed the effects on smoking in secondary school.
In 2002, 121 schools in The Netherlands were randomly assigned to the intervention or control group. The intervention group received 3 lessons in 5th grade of elementary school and a second 3 lessons in 6th grade. The control group received "usual care". Students completed 5 questionnaires: before and after the lessons in 5th and 6th grade and in the first class of secondary school. At baseline, 3173 students completed the questionnaire; 57% completed all questionnaires.
The program had limited effect at the end of elementary school. One year later in secondary school significant effects on behavioral determinants and smoking were found. The intervention group had a higher intention not to smoke (β=0.13, 95% confidence interval=0.01-0.24) and started to smoke less often than the control group (odds ratio=0.59, 95% confidence interval=0.35-0.99): smoking increased from 2.5% to 3.6% in the intervention group and from 3.2% to 6.5% in the control group. Girls showed the largest differences in smoking between intervention and control condition.
A prevention program in elementary school seems to be effective in preventing smoking.
为了让小学生为中学做好准备，我们制定了一个预防吸烟计划。本研究评估了该计划对中学生吸烟的影响。
2002 年，荷兰 121 所学校被随机分为干预组和对照组。干预组在小学五年级接受 3 次课程，并在六年级接受另外 3 次课程。对照组接受“常规护理”。学生们完成了 5 份问卷：在五年级和六年级的课程前后以及中学的第一节课。在基线时，有 3173 名学生完成了问卷；57%的学生完成了所有问卷。
该计划在小学结束时效果有限。一年后，在中学阶段，行为决定因素和吸烟方面的效果显著。干预组比对照组更倾向于不吸烟（β=0.13，95%置信区间=0.01-0.24），开始吸烟的频率也更低（比值比=0.59，95%置信区间=0.35-0.99）：干预组的吸烟率从 2.5%上升到 3.6%，而对照组从 3.2%上升到 6.5%。女孩在干预和对照组之间的吸烟差异最大。
小学预防吸烟计划似乎能有效预防吸烟。
