Household food insecurity and Canadian Aboriginal women's self-efficacy in food preparation.

Purpose: Determinants of self-efficacy related to food preparation using store-bought food were examined in women belonging to the Atikamekw Nation. Also examined was whether self-efficacy was associated with household food insecurity.
Methods: A cross-sectional survey was conducted with 107 women responsible for household food supplies. Two self-efficacy scores were calculated, one for healthy food preparation and one for food preparation in general. Household food insecurity was measured with an adapted version of the United States Food Security Core Module. The other variables were household composition, income sources, food supplies, tobacco use, participants' health status, and lifestyle and sociodemographic characteristics. Multiple linear regression was used to analyze associations between self-efficacy and household food insecurity in 99 participants.
Results: Severe household food insecurity was associated with significantly lower healthy food preparation scores in Atikamekw women. Other associated variables were food supplies, marital status, alcohol consumption, weight status, and understanding of the native language.
Conclusions: Application of the concept of self-efficacy contributes to a better understanding of the factors influencing food preparation in Atikamekw women. In this study, self-efficacy in healthy food preparation was linked to food insecurity and obesity, particularly in the most serious cases. Efforts to improve diet will require not only behavioural interventions, but public policies.
