Objective: Health benefits of diet with sufficient fruit and vegetable (F&V) are well documented. However, large proportions of students in Hong Kong do not fulfill the World Health Organization recommendation of F&V daily consumption. The aim of this paper is to measure and investigate the intention and behaviour of F&V consumption among adolescents in Hong Kong by examining the variables of Theory of Planned Behaviour (TPB). Methods: As a case study, one secondary school in Hong Kong was selected to participate in this research. There were 327 (51.7%) males and 305 (48.3%) females, ranging in age from 11 to 18 years, enrolled in this study. All participants were Chinese. Valid data of 632 students from Form 1 to 5 were measured by self-administered questionnaire with help of class teachers. A validated questionnaire was used to measure the constructs of TPB regarding the F&V consumption behaviour from December 2011 to February 2012. Results: The overall F&V consumption in this study was generally low. Attitude, subjective norm and perceived behavioural control (PBC) accounted for 45% and 37% of the variance in the intention of F&V consumption for male and female respectively, whereas PBC was the strongest predictor and subjective norm was the weakest. In general, the TPB model could explain 14% of the variance in the F&V consumption behaviour. Conclusion: The TPB model provides a useful framework for the study of F&V consumption intention amongst secondary school students in Hong Kong. However, the weak performance of predicting behaviour is still the persistent fault of TPB.
