title: Sodium and nutrition labelling: a qualitative study exploring New Zealand consumers' food purchasing behaviours.
abstract: OBJECTIVE
  Dietary sodium reduction is an important public health intervention that would reduce blood pressure and chronic disease. An understanding of how New Zealand consumers' food purchasing behaviour is influenced by perceptions of dietary sodium will inform future sodium-reduction strategies.
  
  
  METHODS
  The present qualitative study used in-depth interviews of adult consumers to explore consumer knowledge, understanding of food labels and food purchasing behaviour with respect to dietary sodium.
  
  
  METHODS
  New Zealand.
  
  
  METHODS
  A convenience sample of sixteen adult grocery shoppers.
  
  
  RESULTS
  A thematic analysis of the transcripts showed New Zealand consumers lacked the background knowledge necessary to understand and regulate their own salt intake and were unable to interpret existing food labels with respect to dietary salt.
  
  
  CONCLUSIONS
  The findings add further weight to calls for food labels that do not require background knowledge or numerical skills and highlight the need for population-based public health interventions. Education of New Zealand consumers on the health benefits of sodium reduction and how this may be achieved would complement this approach.
