Outline of Final Research Achievements

We studied the relationships between maternal-infant circadian rhythms and maternal subjective symptoms during the child-rearing period. Diurnal fatigue and depressive mood scores showed positive and significant correlations (p<0.05) with the increase in instantaneous mother-infant phase differences, indicating the significant role of synchronization of mother-infant circadian rhythms for maintaining maternal mental health. These findings suggest that modifications of maternal and/or infant circadian rhythms may lead to the improvement of maternal mental health during child-rearing periods.
