Prediction of daily fruit and vegetable consumption among overweight and obese individuals.

The purpose of this study is twofold: to identify the determinants of daily fruit and vegetable (F&V) consumption and the moderators of the intention-behaviour relationship. A sample of 225 overweight or obese adults completed a TPB questionnaire. F&V behaviour was assessed at baseline and three months later. Statistical analyses revealed that past behaviour, perceived behavioural control (PBC) and age were significant predictors of daily F&V consumption. In addition, intention was found to interact with anticipated regret. Interventions should encourage the development of habit and PBC. However, the age and level of anticipated regret of the targeted population should be considered when designing interventions. Copyright 2010 Elsevier Ltd. All rights reserved.
