Smoke-Free Laws and Disparities in Secondhand Smoke Exposure Among Nonsmoking Adults in the United States, 1999-2014.

ABSTRACT:

Introduction

Little is known about the relationship between smoke-free laws and persistent disparities in secondhand smoke (SHS) exposure among nonsmoking adults in the United States.

Aims and methods

We constructed time-varying smoke-free law measures representing whether or not at least 50% of each US county's population was covered by smoke-free laws in workplaces and hospitality venues (restaurants/bars). We merged these data with restricted data on cotinine-derived SHS exposure among nonsmokers from the National Health and Nutrition Examination Survey, 1999-2014 (N = 25 444). Using logistic regression, we estimated associations between smoke-free law coverage and SHS exposure among all nonsmokers, and within age strata (25-39, 40-59, 60+). We explored differential assoc
