“…However, there was a consumption of industrialized foods, introduced by the contact with the surrounding society, causing a change in the food standard, reinforcing an acculturation of the Indians, both urban and rural. Poor food quality on indigenous people has also observed, recently in Australian Indians [14].…”

“…Behaviour‐change outcomes and intervention cost‐effectiveness were reported. A stepped‐wedge randomized controlled trial conducted in remote community stores in the Northern Territory examined the effectiveness of a price discount on purchases with and without consumer education . A natural experiment utilized mixed methods to evaluate the impact of four price discount strategies in remote community stores .…”

SummaryObjectiveFood environments can influence food selection and hold the potential to reduce obesity, non‐communicable diseases and their inequalities. ‘Consumer nutrition environments’ describe what consumers encounter within a food retail outlet, including products, price, promotion and placement. This study aimed to summarize the attributes that have been examined in existing peer‐reviewed studies of Australian consumer nutrition environments, identify knowledge gaps and provide recommendations for future research.MethodsA systematic search of peer‐reviewed literature was conducted. Sixty‐six studies that assessed an aspect of within‐store consumer nutrition environments were included.ResultsMost studies were published from 2011 onwards and were conducted in capital cities and in supermarkets. Studies assessed the domains of product (40/66), price (26/66), promotion (16/66) and placement (6/66). The most common research themes identified were assessment of the impact of area socioeconomic status (13/66), remoteness (9/66) and food outlet type (7/66) on healthy food prices; change in price of healthy foods (6/66); variety of healthy foods (5/66); and prevalence of unhealthy child‐orientated products (5/66).ConclusionsThis scoping review identified a large number of knowledge gaps. Recommended priorities for researchers are as follows: (1) develop consistent observational methodology, (2) consider consumer nutrition environments in rural and remote communities, (3) develop an understanding of food service outlets, (4) build on existing evidence in all four domains of product, price, placement and promotion and (5) determine effective policy and store‐based interventions to increase healthy food selection.

Objective: We compared self‐reported dietary intake from the very remote sample of the National Aboriginal and Torres Strait Islander Nutrition and Physical Activity Survey (VR‐NATSINPAS; n=1,363) to one year of food and beverage purchases from 20 very remote Indigenous Australian communities (servicing ∼8,500 individuals). Methods: Differences in food (% energy from food groups) and nutrients were analysed using t‐test with unequal variance. Results: Per‐capita energy estimates were not significantly different between the surveys (899 MJ/person/day [95% confidence interval −152,1950] p=0.094). Self‐reported intakes of sugar, cereal products/dishes, beverages, fats/oils, milk products/dishes and confectionery were significantly lower than that purchased, while intakes of meat, vegetables, cereal‐based dishes, fish, fruit and eggs were significantly higher (p<0.05). Conclusion: Differences between methods are consistent with differential reporting bias seen in self‐reported dietary data. Implications for public health: The NATSINPAS provides valuable, much‐needed information about dietary intake; however, self‐reported data is prone to energy under‐reporting and reporting bias. Purchase data can be used to track population‐level food and nutrient availability in this population longitudinally; however, further evidence is needed on approaches to estimate wastage and foods sourced outside the store. There is potential for these data to complement each other to inform nutrition policies and programs in this population.
