Population Assessment of Tobacco and Health (PATH) Study [United States] Restricted-Use Files

The PATH Study was launched in 2011 to inform the Food and Drug Administration's regulatory activities under the Family Smoking Prevention and Tobacco Control Act (TCA). The PATH Study is a collaboration between the National Institute on Drug Abuse (NIDA), National Institutes of Health (NIH), and the Center for Tobacco Products (CTP), Food and Drug Administration (FDA). The study sampled over 150,000 mailing addresses across the United States to create a national sample of tobacco users and non-users. 45,971 adults and youth constitute the first (baseline) wave, Wave 1, of data collected by this longitudinal cohort study. These 45,971 adults and youth along with 7,207 "shadow youth" (youth ages 9 to 11 sampled at Wave 1) make make up the 53,178 participants that constitute the Wave 1 Cohort. Respondents are asked to complete an interview at each follow-up wave. Youth who turn 18 by the current wave of data collection are considered "aged-up adults" and are invited to complete the Adult Interview. Additionally, "shadow youth" are considered "aged-up youth" upon turning 12 years old, when they are asked to complete an interview after parental consent. At Wave 4, a probability sample of 14,098 adults, youth, and shadow youth ages 10 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 4. This sample was recruited from residential addresses not selected for Wave 1 in the same sampled PSUs and segments using similar within-household sampling procedures. This "replenishment sample" was combined for estimation and analysis purposes with Wave 4 adult and youth respondents from the Wave 1 Cohort who were in the civilian, noninstitutionalized population at the time of Wave 4. This combined set of Wave 4 participants, 52,731 participants in total, forms the Wave 4 Cohort. Please refer to the Restricted-Use Files User Guide that provides further details about children designated as "shadow youth" and the formation of the Wave 1 and Wave 4 Cohorts.

PATH 研究（路径研究）始于2011年，旨在为食品药品监督管理局（FDA）依据《家庭吸烟预防与烟草控制法案》（TCA）进行的监管活动提供信息。PATH 研究是由美国国家药物滥用研究所（NIDA）、国立卫生研究院（NIH）以及食品药品监督管理局下属的烟草产品中心（CTP）共同合作开展的项目。该研究在美国全国范围内抽取了超过150,000个邮寄地址，以构建一个烟草使用者与非使用者的全国性样本。45,971名成年人和青少年构成了纵向队列研究的第一波（基线）数据，即 Wave 1。这45,971名成年人和青少年以及7,207名“影子青少年”（在 Wave 1 中抽取的9至11岁青少年）共同构成了53,178名参与者的 Wave 1 队列。受访者被要求在每个后续波次完成访谈。在当前数据收集波次中达到18岁的青少年被视为“成年化青少年”，并受邀完成成人访谈。此外，“影子青少年”在12岁时被认定为“成年化青少年”，在获得家长同意后，他们将被要求完成访谈。在 Wave 4 中，从 Wave 4 时的民用、非机构化人群中选取了14,098名成年人、青少年和10至11岁的“影子青少年”的概率样本。该样本是通过与 Wave 1 中相同抽样区域（PSUs）和段落的家庭内部抽样程序相似的流程，从未在 Wave 1 中选中的住宅地址招募的。这一“补充样本”在估计和分析目的上与 Wave 4 成年人和青少年受访者合并，这些受访者来自 Wave 1 队列，并在 Wave 4 时属于民用、非机构化人群。这53,178名 Wave 4 参与者共同构成了 Wave 4 队列。请参阅《受限使用文件用户指南》，以获取有关指定为“影子青少年”的儿童以及 Wave 1 和 Wave 4 队列形成的进一步详细信息。数据集 0001（DS0001）包含了主链接文件的数据。该文件包含42个变量和67,276个案例，提供了每个受访者的唯一识别号码以及他们在每个波次中的受访者类型列表。数据集 1011（DS1011）包含了 Wave 1 成人问卷的数据。该数据文件包含2,021个变量和32,320个案例，每个案例代表一次完成的访谈。数据集 1012（DS1012）包含了 Wave 1 青少年（及家长）问卷的数据。该文件包含1,431个变量和13,651个案例。数据集 1411（DS1411）包含了 Wave 1 成年人状态标识符数据，具有5个变量和32,320个案例。数据集 1412（DS1412）包含了 Wave 1 青少年（及家长）状态标识符数据，具有5个变量和13,651个案例。每个状态标识符数据集都包含相同的5个变量，包括用于将状态标识符与问卷和生物标志物数据链接的 PERSONID，以及3个标识州（州 FIPS、州缩写和州全名）的变量。数据集 2011（DS2011）包含了 Wave 2 成人问卷的数据。该数据文件包含2,421个变量和28,362个案例，其中26,447个案例也完成了 Wave 1 成人问卷。其他1,915个案例是之前完成 Wave 1 青少年问卷的“成年化成年人”。数据集 2012（DS2012）包含了 Wave 2 青少年（及家长）问卷的数据。该数据文件包含1,596个变量和12,172个案例，其中10,081个案例也完成了 Wave 1 青少年问卷。其他2,091个案例是之前作为“影子青少年”抽取的“成年化青少年”。数据集 3011（DS3011）包含了 Wave 3 成人问卷的数据。该数据文件包含2,359个变量和28,148个案例，其中26,241个案例是继续完成先前成人问卷的成年人。其他1,907个案例是之前完成青少年问卷的“成年化成年人”。数据集 3012（DS3012）包含了 Wave 3 青少年（及家长）问卷的数据。该数据文件包含1,492个变量和11,814个案例，其中9,769个案例是继续完成先前青少年访谈的青少年。其他2,045个案例是之前作为“影子青少年”抽取的“成年化青少年”。数据集 3111、3211、3112 和 3212（DS3111、DS3211、DS31
