Population Assessment of Tobacco and Health (PATH) Study [United States] Master Linkage 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 those who do and do not use tobacco. 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 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 the Youth 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 Primary Sampling Units (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. At Wave 7, a probability sample of 14,863 adults, youth, and shadow youth ages 9 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 7. This sample was recruited from residential addresses not selected for Wave 1 or Wave 4 in the same sampled PSUs and segments using similar within-household sampling procedures. This second replenishment sample was combined for estimation and analysis purposes with Wave 7 adult and youth respondents from the Wave 4 Cohort who were at least age 15 and in the civilian, noninstitutionalized population at the time of Wave 7. This combined set of Wave 7 participants, 46,169 participants in total, forms the Wave 7 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, Wave 4, and Wave 7 Cohorts. Dataset 0001 (DS0001) contains the data from the Public-Use File Master Linkage File (PUF-MLF). This file contains 78 variables and 67,276 cases. The file provides a master list of every person's unique identification number and what type of respondent they were in each wave for data that are available in the Public-Use Files and Special Collection Public-Use Files. Dataset 0002 (DS0002) contains the data from the Restricted-Use File Master Linkage File (RUF-MLF). This file contains 188 variables and 82,139 cases. The file provides a master list of every person's unique identification number and what type of respondent they were in each wave for data that are available in the Restricted-Use Files, Special Collection Restricted-Use Files, and Biomarker Restricted-Use Files.

PATH 研究（PATH Study）于2011年启动，旨在为食品药品监督管理局（Food and Drug Administration, FDA）根据《家庭吸烟预防与烟草控制法》（Tobacco Control Act, TCA）所进行的监管活动提供信息。PATH 研究是国家药物滥用研究所（National Institute on Drug Abuse, NIDA）、美国国立卫生研究院（National Institutes of Health, NIH）与食品药品监督管理局烟草产品中心（Center for Tobacco Products, CTP）之间的合作项目。该研究从美国境内超过15万个邮寄地址中抽取样本，构建了一个全国范围内的烟草使用者与非使用者的样本库。其中，45,971名成人和青少年构成了该纵向队列研究的首次（基线）数据收集阶段——第1波（Wave 1）。这45,971名成人和青少年以及7,207名“影子青少年”（在第1波中抽取的9至11岁青少年）共同构成了53,178名参与者的第1波队列。受访者被要求在每次后续波次中完成访谈。到当前数据收集波次时年满18岁的青少年被视为“成年青年”，并受邀完成成人访谈。此外，“影子青少年”在年满12岁时被视为“成年青少年”，在获得家长同意后，他们被要求完成青少年访谈。在第4波中，从第4波时的平民、非机构化人口中随机抽取了14,098名成人、青少年和10至11岁的“影子青少年”。此样本来自未被选入第1波的同一样本初级抽样单位（Primary Sampling Units, PSUs）和区段，并采用类似的户内抽样程序进行招募。这个“补充样本”与第4波队列中的成年和青少年受访者合并，这些受访者在第4波时属于平民、非机构化人口，总计52,731名参与者构成了第4波队列。在第7波中，从第7波时的平民、非机构化人口中随机抽取了14,863名成人、青少年和9至11岁的“影子青少年”。此样本来自未被选入第1波或第4波的同一样本PSUs和区段，并采用类似的户内抽样程序进行招募。这个第二个补充样本与第4波队列中的至少15岁且在第7波时属于平民、非机构化人口的成年和青少年受访者合并，总计46,169名参与者构成了第7波队列。请参阅《受限使用文件用户指南》，其中提供了关于指定为“影子青少年”的儿童以及第1波、第4波和第7波队列形成的相关详细信息。数据集0001（DS0001）包含了公共使用文件主链接文件（Public-Use File Master Linkage File, PUF-MLF）中的数据。此文件包含78个变量和67,276个案例。该文件提供了每个个人的唯一识别号码以及在每个波次中他们所担任的受访者类型的主列表，这些数据均可在公共使用文件和特别收集公共使用文件中找到。数据集0002（DS0002）包含了受限使用文件主链接文件（Restricted-Use File Master Linkage File, RUF-MLF）中的数据。此文件包含188个变量和82,139个案例。该文件提供了每个个人的唯一识别号码以及在每个波次中他们所担任的受访者类型的主列表，这些数据均可在受限使用文件、特别收集受限使用文件和生物标志物受限使用文件中找到。
