title: Secondhand Smoke Exposure 7 Years After an Indoor Smoke-Free Law.
abstract: To examine locations of secondhand smoke (SHS) exposure among nonsmokers, 7 years after a statewide smoke-free policy.
  
  
  
  Data collected via statewide, random digit dial telephone survey. Response rates were 64.7% for landline and 73.5% for cell phone.
  
  
  
  Minnesota, 2014.
  
  
  
  Representative sample of 7887 nonsmoking adults.
  
  
  
  Self-reported locations of SHS exposure and opinions on smoke-free restrictions.
  
  
  
  Descriptive statistics and logistic regression.
  
  
  
  A total of 35.5% of nonsmokers reported SHS exposure in the past 7 days. The greatest proportion of exposure occurred in community settings (31.7%) followed by cars (6.9%) and in the home (3.2%). Young adults were more likely to be exposed in a home or car than older adults. Nonsmokers living with a smoker were 39.6 (20.6-75.8) times more likely to be exposed to SHS in their home and 5.3 (4.1-6.8) times more likely to be exposed in a car, compared to those who did not live with a smoker.
  
  
  
  SHS exposure continues after comprehensive smoke-free policies restricted it from public places. Disparities in exposure rates exist for those who live with a smoker, are young, and have low incomes. Findings suggest the need for additional policies that will have the greatest public health benefit.
