Abstract

BACKGROUND

As a legal obligation, the Dutch government publishes online information about tobacco additives to make sure that it is publicly available. Little is known about the influence this website ("tabakinfo") has on visitors and how the website is evaluated by them.

OBJECTIVE

This study assesses how visitors use the website and its effect on their knowledge, risk perception, attitude, and smoking behavior. The study will also assess how the website is evaluated by visitors using a sample of the Dutch general population, including smokers and nonsmokers.

METHODS

A randomized controlled trial was conducted, recruiting participants from an online panel. At baseline, participants (N=672) were asked to fill out an online questionnaire about tobacco additives. Next, participants were randomly allocated to either one of two experimental groups and invited to visit the website providing information about tobacco additives (either with or without a database containing product-specific information) or to a control group that had no access to the website. After 3 months, follow-up measurements took place.

RESULTS

At follow-up (n=492), no statistically significant differences were found for knowledge, risk perception, attitude, or smoking behavior between the intervention and control groups. Website visits were positively related to younger participants (B=-0.07, 95% CI -0.12 to -0.01; t=-2.43, P=.02) and having a low risk perception toward tobacco additives (B=-0.32, 95% CI -0.63 to -0.02; t=-2.07, P=.04). In comparison, having a lower education (B=-0.67, 95% CI -1.14 to -0.17; t=-2.65, P=.01) was a significant predictor for making less use of the website. Furthermore, the website was evaluated less positively by smokers compared to nonsmokers (t=-3.55, P<.001), and males compared to females (t=-2.21, P=.02).

CONCLUSIONS

The website did not change perceptions of tobacco additives or smoking behavior. Further research is necessary to find out how online information can be used to effectively communication about the risks of tobacco additives.

摘要

背景

作为一项法定义务，荷兰政府在网上发布有关烟草添加剂的信息，以确保公众能够获取。对于该网站（“烟草信息”）对访问者的影响以及访问者如何对其进行评价，我们了解甚少。

目的

本研究评估访问者如何使用该网站及其对他们的知识、风险认知、态度和吸烟行为的影响。该研究还将使用包括吸烟者和非吸烟者在内的荷兰普通人群样本，评估访问者对该网站的评价。

方法

进行了一项随机对照试验，从一个在线小组招募参与者。在基线时，参与者（N = 672）被要求填写一份关于烟草添加剂的在线问卷。接下来，参与者被随机分配到两个实验组之一，并被邀请访问提供烟草添加剂信息的网站（一个有包含特定产品信息的数据库，另一个没有），或者被分配到无法访问该网站的对照组。3个月后进行随访测量。

结果

在随访时（n = 492），干预组和对照组在知识、风险认知、态度或吸烟行为方面未发现统计学上的显著差异。网站访问与年轻参与者呈正相关（B = -0.07，95%CI -0.12至-0.01；t = -2.43，P = 0.02），并且对烟草添加剂的风险认知较低（B = -0.32，95%CI -0.63至-0.02；t = -2.07，P = 0.04）。相比之下，受教育程度较低（B = -0.67，95%CI -1.14至-0.17；t = -2.65，P = 0.01）是较少使用该网站的一个显著预测因素。此外，与非吸烟者相比，吸烟者对该网站的评价较低（t = -3.55，P < 0.001），与女性相比，男性对该网站的评价较低（t = -2.21，P = 0.02）。
