Associations between Shokuiku during School Years, Well-Balanced Diets, and Eating and Lifestyle Behaviours in Japanese Females Enrolled in a University Registered Dietitian Course

This study comprehensively examined the associations between shokuiku (food and nutrition education) during school years, current well-balanced diets, and current eating and lifestyle behaviours of Japanese female university students. A hypothetical model was developed using factors potentially associated with well-balanced diets. A simultaneous multipopulational analysis was performed according to the living arrangements of 148 female Japanese students (48.6% living alone) from a registered dietitian course. The analysis showed acceptable goodness of fit and a significant positive path from shokuiku during school years (living alone: standardised estimate 0.29, p = 0.004; with family: 0.32, p = 0.006) and a negative path from eating out frequency (−0.19, p = 0.039; −0.24, p = 0.017) towards a well-balanced diet. A significant negative path was identified from late bedtimes (−0.45, p < 0.001) and home meal replacement use frequency (−0.24, p = 0.010) in those living alone and from late-night snacking frequency (−0.27, p = 0.007) in those living with family. Well-balanced diets in female university students may be positively associated with shokuiku during school years and limited by a late bedtime, eating out, and home meal replacement use in those living alone, and by late-night snacking and eating out in those living with family.
