Population Assessment of Tobacco and Health (PATH) Study [United States] Special Collection Public-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 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 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. Please refer to the Public-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. Wave 4.5 was a special data collection for youth only who were aged 12 to 17 at the time of the Wave 4.5 interview. Wave 4.5 was the fourth annual follow-up wave for those who were members of the Wave 1 Cohort. For those who were sampled at Wave 4, Wave 4.5 was the first annual follow-up wave. Wave 5.5, conducted in 2020, was a special data collection for Wave 4 Cohort youth and young adults ages 13 to 19 at the time of the Wave 5.5 interview. Also in 2020, a subsample of Wave 4 Cohort adults ages 20 and older were interviewed via the PATH Study Adult Telephone Survey (PATH-ATS). Dataset 1002 (DS1002) contains the data from the Wave 4.5 Youth (and Parent) Questionnaire. This file contains 1,395 variables and 13,131 cases. Of these cases, 11,378 are continuing youth having completed a prior Youth Interview. The other 1,753 cases are "aged-up youth" having previously been sampled as "shadow youth." Datasets 1112, 1212, and 1222, (DS1112, DS1212, and DS1222) are data files comprising the weight variables for Wave 4.5. The "all-waves" weight file contains weights for participants in the Wave 1 Cohort who completed a Wave 4.5 Youth Interview and completed interviews (if old enough to do so) or verified their information with the study (if not old enough to be interviewed) in Waves 1, 2, 3, and 4. There are two separate files with "single wave" weights: one for the Wave 1 Cohort and one for the Wave 4 Cohort. The "single-wave" weight file for the Wave 1 Cohort contains weights for youth who completed an interview in Wave 1 and in Wave 4.5, regardless of their participation in the intervening waves. The "single-wave" weight file for the Wave 4 Cohort contains weights for all Wave 4.5 Youth Interview respondents in the Wave 4 Cohort. Dataset 1503 (DS1503) contains data derived from responses to questionnaires in Wave 1, Wave 2, Wave 3, Wave 4, and Wave 4.5 indicating if participants had ever/never used various tobacco products as of the Wave 4.5 data collection period. This data file contains 26 variables for all 67,276 study participants as of the Wave 4.5 data collection. This file is provided for reference only to simplify the definitions of tobacco use variables in the Adult and Youth data files for subsequent waves.Dataset 2001 (DS2001) contains the data from the Wave 5.5 Adult Questionnaire. This file contains 2,323 variables and 3,628

PATH 研究（路径研究）始于2011年，旨在为食品药品监督管理局（FDA）根据《家庭吸烟预防与烟草控制法案》（TCA）开展的监管活动提供信息。PATH 研究由美国国家药物滥用研究所（NIDA）、国家卫生研究院（NIH）和食品药品监督管理局烟草产品中心（CTP）联合发起。研究从美国150,000个邮寄地址中抽取样本，构建了全国范围内的烟草使用者及非使用者样本。45,971名成人和青少年构成了该纵向队列研究的首次（基线）数据收集波次——波次1。这45,971名成人和青少年，以及7,207名“影子青少年”（在波次1中抽取的9至11岁青少年）共同构成了53,178名参与者的波次1队列。受访者被要求在每个后续波次完成访谈。至当前数据收集波次达到18岁的青少年被视为“成年青少年”，并受邀完成成人访谈。此外，“影子青少年”在12岁时被视为“成年青少年”，在获得家长同意后，他们将被要求完成访谈。在波次4中，从当时的民用、非机构化人群中随机抽取了14,098名成人、青少年和10至11岁的“影子青少年”作为样本。该样本来自未在波次1中选取的相同初级抽样单位（PSUs）和区段中的住宅地址，并采用类似的户内抽样程序进行招募。这一“补充样本”在估计和分析目的上与波次4队列中的波次1成年人和青少年受访者相结合。这组结合的波次4参与者，总计52,731人，构成了波次4队列。请参阅公共使用文件用户指南，以获取有关被指定为“影子青少年”的儿童以及波次1和波次4队列形成的进一步详情。波次4.5是对当时在波次4.5访谈中年龄为12至17岁的青少年进行的特殊数据收集。波次4.5是波次1队列成员的第四次年度随访波次。对于在波次4中抽取的样本，波次4.5是他们的首次年度随访波次。2020年进行的波次5.5是对波次4队列中当时在波次5.5访谈中年龄为13至19岁的青少年和年轻成人进行的特殊数据收集。同年，通过PATH研究成人电话调查（PATH-ATS）对波次4队列中20岁及以上的成年人进行了抽样访谈。数据集1002（DS1002）包含波次4.5青少年（及家长）问卷的数据。该文件包含1,395个变量和13,131个案例。在这些案例中，11,378名是持续参与的青少年，他们已完成先前的青少年访谈。其他1,753个案例是“成年青少年”，他们之前已被抽样为“影子青少年”。数据集1112、1212和1222（DS1112、DS1212和DS1222）是包含波次4.5的权重变量的数据文件。该“全波次”权重文件包含波次1队列中完成波次4.5青少年访谈并在波次1、2、3和4中完成访谈（如果年龄足够）或通过研究验证信息（如果年龄不足够被访谈）的参与者的权重。存在两个单独的“单波次”权重文件：一个针对波次1队列，一个针对波次4队列。波次1队列的“单波次”权重文件包含在波次1和波次4.5中完成访谈的青少年的权重，无论他们在中间波次是否参与。波次4队列的“单波次”权重文件包含波次4队列中所有波次4.5青少年访谈受访者的权重。数据集1503（DS1503）包含来自波次1、波次2、波次3、波次4和波次4.5问卷的回答，表明截至波次4.5数据收集期，参与者是否曾使用过各种烟草产品。该数据文件包含26个变量，涵盖了67,276名研究参与者。该文件仅提供参考，以简化后续波次的成人及青少年数据文件中烟草使用变量的定义。数据集2001（DS2001）包含波次5.5成人问卷的数据。该文件包含2,323个变量和3,628个案例。
