CANCELED: Methodological Aspects for Estimating Age of Initiation of E-Cigarettes and Cigars Using Interval Censoring With Balanced Repeated Replication Weights in a National Representative Cohort

There is a lack of research on prospectively estimating the distribution of the age of initiation of electronic cigarette use in U.S. youth. Younger ages of initiation of tobacco product use are associated with greater exposure to nicotine, and a 2017 meta-analysis found that e-cigarette use was associated with subsequent cigarette initiation. This seminar will provide (i) a quick overview of using the Balanced repeated replication (BRR) statistical technique for estimating the sampling variability of a statistic obtained by stratified sampling; (ii) an overview of the sampling design of the national representative cohort called the Population Assessment of Tobacco and Health (PATH) and tobacco regulatory science; (iii) a quick overview of interval censoring within the context of survival analysis; (iv) describe the methodological aspects for estimating time to event with interval censoring and BRR when software is not directly available for non-parametric estimation and comparison with several assumed parametric distributions. Among youth (ages 12-17 years old) never e-cigarette users in PATH 2013-2014, the estimation of the average age of e-cigarette initiation as well as cigar initiation prospectively from PATH 2015-2017 will be summarized. Recommendations for intervention programs on tobacco regulatory science for youth will be discussed.
