What are the determinants of food security among regional and remote Western Australian children?

Objective: To explore how determinants of food security affect children in regional and remote Western Australia (WA), across food availability, access and utilisation dimensions. Methods: The Determinants of Food Security framework guided the thematic analysis (using NVivo 10) of semi-structured interviews with 20 key informants. Results: Food availability factors included availability, price, promotion, quality, location of outlets and variety. Food access factors included social support, financial resources, transport to food outlets, distance to food outlets and mobility. Food utilisation factors included nutrition knowledge and skills, children's food preferences, storage facilities, preparation and cooking facilities and time to purchase food. Conclusions: Key food availability recommendations include increasing local food supply options. Food access recommendations include ensuring equitable formal social support and empowering informal support options. Food utilisation recommendations include prioritising food literacy programs focusing on quick, healthy food preparation and budgeting skills. Implications for public health: Policymakers should invest in local food supply options, equitable social support services and experiential food literacy programs. Practitioners should focus child/parent programs on improving attitude, knowledge and skills.
