Objective: Thhis study aimed to investigate the reason why people choose to consume less vegetable and fruit through examining how the stage of change and psycho-social parameters relate to vegetable and fruit intake.
Methods: We carried out a cross-sectional study in 4 regions of Japan in which 2308 individuals (1012 men and 1296 women) aged 18 years or older who completed the questionnaires were included in the study.
Results: The results showed 56% of the participants were in the precontemplation stage (not thinking about consuming recommended amount of fruit and vegetable) and their average amounts of vegetable and fruit intake
were far below the level of current recommendations, and subjects in the precontemplation stage showed lower scores of attitude and self efficacy. Men were more likely to be in precontemplation (67.7%) and less likely to be in
action/maintenance stage (7.9%) than women (46.9%, 12.1%, respectively) (p < 0.001). We also observed the scores of attitude (p = 0.06) and self-efficacy (p < 0.01) rose as the stage went up from the precontemplation to
action/maintenance for increasing vegetable and fruit intake. Moreover, a linear trend was found toward higher vegetable (p < 0.05) and fruit (p = 0.121) intake from precontemplation to action/maintenance stage.
Conclusion: The present evidence suggests more attention should be focused on strategy for perceptions of personal need for recommended amount of vegetable and fruit intake for those who are in the precontemplation
stage. Moreover, effective programs on enhancement of self-efficacy and attitude toward vegetable and fruit consumption are needed for increasing the vegetable and fruit intake.
