摘要：In Japan, the amount of vegetable intake in young adults, especially at breakfast, is low. We aimed to examine the factors associated with vegetable intake at breakfast among young adults. In 2016, a self-administered questionnaire survey was conducted at a Japanese university. The questionnaire measured the frequency of ≥70 g vegetable intake at breakfast, lifestyle, eating habits, environmental factors, knowledge and attitudes (including the variable “Perceived behavior control (PBC)”, from the Theory of Planned Behavior). The data of 1,455 male students who usually ate breakfast were analyzed. They were divided into two groups based on the median of the frequency of vegetable intake and the above factors were compared using a chi-squared test by living condition. The significant factors were subsequently entered into a logistic regression analysis as independent variables. Eating breakfast with family or friends and PBC were positively associated with vegetable intake in students living with their family. Often doing one’s own cooking, having knowledge about a well-balanced diet, and PBC were positively associated with vegetable intake in students living alone. Along with PBC, different factors pertaining to an individual’s living condition may need to be considered to increase vegetable intake at breakfast.
