| Outline of Final Research Achievements |
To investigate relationship between reproductive function and dietary habits, we conducted the questionnaire survey for female college students corresponding to “post-adolescent stage” when the sexual maturation proceeds after menarche. The results showed that skipping breakfast is associated with dysmenorrhea and irregular menses. Consequently, to further confirm the adverse effects of the inadequate timing of food intake during circadian rhythmus on reproductive function, we additionally performed animal experiments using young adult female rats, and found that estrus cycle was disturbed when food intake was strictly limited to the non-active period (light phase). These results strongly suggest that the timing of food intake during circadian rhythmus is one of important factors that regulate female reproductive function. Our findings will also contribute to developing a new dietary education program to reduce the adverse effects on reproductive functions in young women.
