Tobacco Use Among Argentinian Youth: A Cohort Study

描述（由申请人提供）：吸烟行为以及影响这种行为的价值观和信念是在儿童和青少年时期获得的，并受到个人、文化、家庭和社会因素的严重影响。为了进一步了解青少年的吸烟行为，我们将在阿根廷胡胡伊省（之后是胡胡伊）的两个种族（科拉族和欧洲裔）的高中青少年中进行一项纵向学校调查。具体而言，本研究的目的是评估吸烟行为的流行程度，以及与该人群中吸烟行为相关的易感因素、强化因素和促进因素。在描述性研究的基础上，我们将在不同社会和文化特征的青少年中开发和试点测试烟草预防干预的组成部分。最后，我们将为来自胡胡伊和阿根廷西北部的研究人员实施多部分培训。本研究的具体目的如下：

DESCRIPTION (provided by applicant): Smoking behavior and the values and beliefs that influence this behavior are acquired during childhood and adolescence and are heavily influenced by individual, cultural, familial, and social factors. To further our knowledge of the smoking behavior of adolescents, we will conduct a longitudinal school based survey among high school youth of two ethnic groups (Kolla and European descent) in the province of Jujuy, Argentina (Jujuy thereafter). Specifically, the goals of this study are to assess the prevalence of smoking behavior, as well as the predisposing, reinforcing, and facilitating factors associated with smoking acquisition within this population. Based on the descriptive study, we will develop and pilot test components of a tobacco prevention intervention across youth of different social and cultural characteristics. Finally, we will implement a multicomponent training component for researchers from Jujuy and northwest Argentina. The specific aims of the study are as follows: Aim 1. To identify the patterns of transition from smoking susceptibility to initiation to experimentation to regular smoking in a cohort of 3000 urban and rural 8th grade public high school youth of Kolla and European descent in Jujuy for a period of three years. Aim 2. To define the personal, interpersonal, cultural, and contextual factors (e.g., peer influence, the value of health, urban/rural residence, socioeconomic status, media exposure, and smoking restrictions) that affect the development of smoking among a cohort of 3,000 8th grade students of Kolla and European descent. Aim 3. To develop and pilot test components of a culturally appropriate intervention in the public high school, of Jujuy with the goal of modifying smoking behavior. The intervention will target modification of predisposing and reinforcing factors for smoking.
