Abstract:

Aim: This study sought to investigate the effects of body-weight-based compared to health-based public health messages for encouraging fruit and vegetable consumption, dependent on gender and age, while also gauging adverse consequences. Subject and methods: Using an independent groups design, male and female participants, aged 18–65 years, were randomized to view either a weight-based (N = 245) or a health-based (N = 231) public health message for increasing fruit and vegetable consumption, and intentions to consume, immediate selection and subsequent consumption of fruit and vegetables and biscuit/cake-bars, adverse consequences and various confounders were assessed. Results: Weight-based messages resulted in greater immediate selection and subsequent fruit and vegetable consumption compared to health-based messages in females (smallest Beta = 0.375, p = 0.04), specifically younger females (least significant Beta = 0.683, p = 0.04). No effects were found in males. Intentions to consume fruit and vegetables, biscuit/cake-bars and subsequent biscuit/cake-bar consumption were predicted only by confounders. Adverse consequences of the messages were low (χ2(1) = 44.16, p < 0.05; smallest t(148) = 10.22, p < 0.01), and did not differ between weight-based and health-based messages (χ2(2) = 2.72, p > 0.05; largest t(278) = 0.75, p = 0.46). Conclusions: This work demonstrates a role for weight-based compared to health-based public health promotion messages for increasing fruit and vegetable selection and consumption in young females. Adverse consequences following the messages were low, but care may still be needed.
