title: Infant secondhand smoke exposure in Louisiana, 1998-2004: trend and high risk population.
abstract: OBJECTIVE
  To evaluate the trend of infant secondhand smoke exposure (ISHSE) at home from 1998 to 2004 and define high risk infants exposed to secondhand smoke.
  
  
  METHODS
  1998-2004 Louisiana Pregnancy Risk Assessment Monitoring System data were used. Logistic regression was applied to determine the trend of ISHSE and define variables associated with ISHSE.
  
  
  RESULTS
  Adjusted annual percent increase of odds of ISHSE was 9.0% (p = .0020) among blacks. Adjusted annual percent decrease of odds of ISHSE was 5.0% (p = .0084) among whites. Adjusted odds of ISHSE was higher among women with characteristics as follows: currently smoked, age < 20 years, < high school education, unmarried, never breastfed their infants, had term delivery or deliveries paid for by Medicaid.
  
  
  CONCLUSIONS
  Prevalence of ISHSE increased in blacks and decreased in whites between 1998 and 2004. Smoking status, maternal age, education, marital status, delivery payment source, delivery status, and breastfeeding status were associated with ISHSE.
