How gender, education and nutrition knowledge contribute to food insecurity among adults in Australia

Food and nutrition insecurity occurs when healthy and safe food cannot be obtained by socially acceptable means and arises as a result of complex interactions between socioeconomic and demographic determinants. These factors contribute to discrepancies in health and well-being between men and women and may also explain differential rates of food insecurity. The objectives of this cross-sectional study were to investigate the intersection between gender, education, nutrition knowledge and food security status within a high-income country context. Australian adults over 16 years of age who identified as having primary responsibility for food in their household were recruited via social media and a panel. Respondents completed a self-administered survey that included sociodemographic data, nutrition-related knowledge and food security status. Food security was measured using the Australian Household Food and Nutrition Security Scale an adapted version of the United States Department of Agriculture Household Food Security Survey. Among the 1010 survey respondents, household food insecurity (HFI) was highly prevalent (43% were food insecure, with 26% of these severely food insecure). Gender may affect associations between education, nutrition knowledge and HFI. Education was significantly associated with HFI among women but not among men. Conversely, nutrition knowledge was significantly inversely associated with food security among men but not among women. Differences in determinants of HFI exist between men and women, and programs aimed at addressing food insecurity may be more effective if tailored accordingly to account for the social and demographic factors associated with HFI.
