The objective of this study was to investigate the prevalence of the following risk behaviors: experimentation with cigarettes, electronic cigarettes, alcohol, substances, delinquent behavior, and sex at age 15, stratified by sex and socioeconomic position. We also investigated the prevalence of cigarette and alcohol experimentation at age 11 and the persistence and cumulative incidence of these behaviors between 11 and 15 years of age.
In this cohort study, we included 3,491 11-year-olds and 1,949 15-year-olds from the 2004 Pelotas Birth Cohort. All outcomes were identified via confidential questionnaires and were analyzed as binary variables.
At age 11, there was a higher prevalence of cigarette experimentation among boys. At age 15, there was a higher prevalence of experimentation with alcohol, cigarettes, and substances among girls; experimentation with cigarettes and sex were more prevalent among those in a low socioeconomic position. We found a high cumulative incidence of alcohol experimentation, as well as persistent alcohol experimentation, in both boys and girls.
Further research should clarify causal paths of the high prevalence of risk behaviors during adolescence and its increase among girls.
本研究旨在调查以下风险行为的流行率：15 岁时尝试吸烟、电子烟、饮酒、使用药物、不良行为和性行为，并按性别和社会经济地位进行分层。我们还调查了 11 岁时尝试吸烟和饮酒的流行率，以及这些行为在 11 岁至 15 岁之间的持续和累积发生率。
在这项队列研究中，我们纳入了来自 2004 年佩洛塔斯出生队列的 3491 名 11 岁儿童和 1949 名 15 岁儿童。所有结局均通过保密问卷确定，并作为二项变量进行分析。
11 岁时，男孩尝试吸烟的比例较高。15 岁时，女孩尝试饮酒、吸烟和使用药物的比例较高；社会经济地位较低的女孩尝试吸烟和性行为的比例较高。我们发现，男孩和女孩的酒精试验累积发病率都很高，且酒精试验持续存在。
进一步的研究应阐明青春期高风险行为的高发率及其在女孩中增加的因果途径。
