Brief summary

Aim: To investigate the effects of a reduced sodium bread on sales and overall sodium intake in remote Indigenous communities. Study design: Communities stores will receive salt-reduced study bread (300mg/100g) (intervention communities) or regular salt study bread (400mg/100g) (control communities) to stock on store shelves for 12 weeks. Population: Remote Indigenous communities serviced by Arnhemland Progress Aboriginal Corporation (ALPA) or Outback Stores (OBS) in Northern Territory, Western Australia or South Australia and where Study bread represents >=45% of the market share for bread sales will be invited to the study (29 communities meet this criteria). Outcomes: - Change in sales (market share and total dollars) - Change in total sodium of all food and drink purchases

Interventions

Intervention stores will receive salt-reduced white bread (300mg/100g) on their store shelves for 12 weeks. The bread packaging will not be distinguishable from the control bread, however the markings on the carton the bread is packed in will differ to reduce the risk of the reduced salt bread being delivered to the control community or vice versa. In addition the price look up code (PLU) differed between the breads, to allow us to ensure that the correct bread is being sold in control and inte
