We investigated relationships between ideological beliefs (i.e., diaphanous body image and environmental concerns), food attitudes, evening meal patterns, physical activity, and Body Mass Index (BMI). A behavioural model was hypothesized based on the Theory of Reasoned Action. A survey was conducted among shoppers aged 40-70 years at Eastland Shopping Centre, Melbourne, Australia. The hypothesized model was tested among female baby boomers (n = 547) for younger (n = 245) and older (n = 302) age groups using structural equation modeling. Findings showed that diaphanous body image had a direct and positive influence on negative food attitudes, which is likely to lead to higher BMI for both age groups. Body image beliefs were positively related to physical activity only for women aged 56-70 years. In contrast, among women aged 40-55 years, strong pro-environmental concerns suggested less consumption of both healthy (e.g., fruit and vegetables) and unhealthy (e.g., sugar and fats) foods. Moreover, strong pro-animal concerns resulted in higher BMI for the younger women. As expected, increased physical activity negatively influenced BMI. Importantly, the associations between ideological beliefs, attitudes, evening meal patterns, and BMI differed between younger and older female baby boomers.
