Optimising women’s diets. An examination of factors that promote healthy eating and reduce the likelihood of unhealthy eating

The majority of nutrition promotion research that has examined the determinants of unhealthy or healthy dietary behaviours has focused on factors that promote consumption of these foods, rather than factors that may both promote healthy eating and buffer or protect consumption of unhealthy foods. The purpose of this paper is to identify factors that both promote healthy eating and also reduce the likelihood of eating unhealthily amongst women. A community sample of 1013 Australian women participated in a cross-sectional self-report survey that assessed factors associated with diet and obesity. Multiple logistic regressions were used to examine the associations between a range of individual, social and environmental factors and aspects of both healthy and unhealthy eating, whilst controlling for key covariates. Results indicated that women with high self efficacy for healthy eating, taste preferences for fruit and vegetables, family support for healthy eating and the absence of perceived barriers to healthy eating (time and cost) were more likely to consume components of a healthy diet and less likely to consume components of a unhealthy diet. Optimal benefits in overall diet quality amongst women may be achieved by targeting factors associated with both healthy and unhealthy eating in nutrition promotion efforts.

► We identify factors that both promote healthy eating and reduce unhealthy eating amongst women.
► Confidence in eating healthily was associated with healthy and unhealthy dietary outcomes.
► Perceiving ample healthy options for eating out was unrelated to all four dietary outcomes.
► Proximal, rather than distal factors appear more predictive of healthy and unhealthy eating.
