Geographic Representativeness of a Digital Tobacco Cessation Intervention: An Exploration of Changes in Rural Reach From 2013-2020.

ABSTRACT:

Background

This study examines the geographic representativeness of people who smoke, among newly registered users of a free digital tobacco cessation program ('EX').

Methods

User-provided ZIP codes from EX® Program registrants were mapped to Rural Urban Continuum Codes (RUCC). Reach Ratios (ReRas) and 95% confidence intervals were used to determine the extent to which geographic representation in EX was proportionate to their representation in the national population of individuals who smoke, as obtained from the United States National Survey of Drug Use and Health (2018-2020). Under- and overrepresentation was demonstrated by ReRas <1 or >1, respectively. Joinpoint regression analyses were used to determine significant changes in trend for ReRas from 2013 to 2020.
