title: Do responsible beverage service programs reduce breath alcohol concentration among patrons: a five-month follow-up of a randomized controlled trial.
abstract: OBJECTIVE
  To examine whether the decrease in the mean breath alcohol concentration (BrAC) and the rowdy social atmosphere reported after one month remained stable in the five-month assessment.
  
  
  METHODS
  Randomized controlled trial.
  
  
  METHODS
  University bars.
  
  
  METHODS
  The five-month assessment was based on 596 students visiting student bars during ordinary pub evenings.
  
  
  METHODS
  Bartenders (n = 40) in 6 of 12 bars on a university campus underwent training programs in a randomized pattern. Bartenders in control bars did not participate in the program.
  
  
  METHODS
  The BrAC and reported social atmosphere in a five-month follow-up assessment.
  
  
  RESULTS
  All measurements (BrAC, rowdy, cozy, and high social atmosphere) showed that time had a significant decreasing effect. The positive effects on BrAC and rowdy atmosphere shown in the one-month follow-up were no longer evident after five months.
  
  
  CONCLUSIONS
  The positive results after one month were not stable after five months. The study's limitations are noted.
