| Outline of Final Research Achievements |
We investigated the contributing factors in preschool children who wake up independently and evaluated the effects of improving lifestyle habits using salivary cortisol as a stress indicator. The salivary cortisol concentration of preschool children who wake up independently follows a typical circadian rhythm, and the cortisol awakening response tended to be low among children who do not wake up independently. We asked parents to proactively feed calcium-containing foods to target preschool children. A strong correlation was observed between salivary cortisol concentrations and sampling time, and no difference was observed in the concentrations before and after the intervention. Although the effect of meal improvement on waking independently could not be clarified, the daytime saliva cortisol concentration of preschool children who wake up independently and those who became able to wake up independently tended to be low and they tended to consume a lot of foods containing calcium.
