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 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 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

PATH 研究（PATH Study）自2011年启动，旨在为食品药品监督管理局（Food and Drug Administration，简称FDA）在《家庭吸烟预防与烟草控制法》（Family Smoking Prevention and Tobacco Control Act，简称TCA）框架下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，简称NIDA）、国家卫生研究院（National Institutes of Health，简称NIH）与食品药品监督管理局烟草产品中心（Center for Tobacco Products，简称CTP）之间的合作项目。研究通过对美国超过15万个邮寄地址进行抽样，构建了一个全国性的烟草使用与非使用人群样本。该研究的第一波（基线波次）数据收集包括了45,971名成年人和青少年。这45,971名成年人和青少年，以及7,207名“影子青少年”（在第一波次中抽取的9至11岁青少年）共同构成了53,178名参与者的第一波次队列。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“成年青少年”，并受邀完成成年访谈。此外，“影子青少年”在12岁时被视为“成年青少年”，在此年龄后，在家长同意的情况下，他们被要求完成访谈。在第四波次（Wave 4）中，从第四波次时的平民、非机构化人群中随机选取了14,098名成年人、青少年和10至11岁的“影子青少年”作为样本。该样本来自未在第一波次中选取的同一抽样初级抽样单位（Primary Sampling Units，简称PSUs）和区段，并采用了类似的户内抽样程序。这个“补充样本”与第四波次队列中来自第一波次的、在第四波次时仍处于平民、非机构化状态下的成年人和青少年受访者合并，形成了包含52,731名参与者的第四波次队列。请参阅公共使用文件用户指南，该指南提供了关于被指定为“影子青少年”的儿童以及第一波次和第四波次队列形成的更多详细信息。第四波次附加波（Wave 4.5）是针对第四波次时年龄在12至17岁之间的青少年进行的特别数据收集。Wave 4.5是第一波次队列成员的第四次年度随访波次。对于在第四波次中抽取的受访者，Wave 4.5是他们的首次年度随访波次。第五波次附加波（Wave 5.5），于2020年进行，是针对第五波次队列中的13至19岁青少年和年轻成人进行的特别数据收集。同样在2020年，通过PATH研究成年电话调查（PATH-ATS）对第四波次队列中20岁及以上的成年受访者进行了抽样调查。数据集1002（DS1002）包含了第四波次附加波青少年和家长问卷的数据。该文件包含1,395个变量和13,131个案例。在这些案例中，11,378个是继续参与青少年访谈的案例。其余1,753个案例是之前作为“影子青少年”被抽取的“成年青少年”。数据集1112、1212和1222（DS1112、DS1212和DS1222）是构成第四波次附加波权重变量的数据文件。包含所有波次权重的文件包含了在第一波次队列中完成第四波次附加波青少年访谈，并在波次1、2、3和4中完成访谈（如果年龄足够）或通过研究验证了其信息（如果年龄不足以接受访谈）的参与者的权重。有两个单独的“单波次”权重文件：一个用于第一波次队列，另一个用于第四波次队列。第一波次队列的“单波次”权重文件包含了在第一波次和第四波次附加波次中完成访谈的青少年的权重，无论他们是否参与了中间的波次。第四波次队列的“单波次”权重文件包含了第四波次队列中所有第四波次附加波次青少年访谈受访者的权重。数据集1503（DS1503）包含了对第一波次、第二波次、第三波次、第四波次和第四波次附加波次中问卷的回答进行整理的数据，这些回答表明了参与者截至第四波次附加波次数据收集期间是否曾使用过各种烟草产品。该数据文件包含26个变量，涉及截至第四波次附加波次数据收集时的所有67,276名研究参与者。该文件仅作为参考提供，以简化后续波次成年人和青少年数据文件中烟草使用变量的定义。数据集2001（DS2001）包含第五波次附加波成年问卷的数据。该文件包含2,323个变量。
