An integrated questionnaire was administered to 275 university students (females: 173, males: 93, unknown: 9) aged 19 - 37 (mean age: 21.9 years) in Hyogo Prefecture, Japan. The questionnaire consisted of basic questions about attributes, questions on sleep habits and sleep quality (Monroe’s sleep quality index), the Torsvall-?kerstedt Diurnal Type Scale and the Impact of Event Scale-Revised (IES-R) to obtain PTSD scores. Participants who scored 25 or more in the IES-R were placed in a high-traumatic group (HTG) and those who scored less than 25 were placed in a low-traumatic group (LTG). HTG participants exhibited significantly worse sleep quality than LTG participants (p < 0.001). Although there was no significant difference in sleep latency (p > 0.05), HTG participants woke more frequently during sleep (p < 0.001) and had more difficulty falling asleep (p = 0.001) than LHG participants. Significantly more LTG participants fell asleep easily and slept deeply than HTG participants (p = 0.005, p = 0.011). Only among females, HTG participants were more evening-typed than LTG participants (p = 0.035). These results suggest that people who suffered a disaster in childhood and currently have PTSD have difficulty achieving high sleep quality. Evening-type lifestyles may reinforce the symptoms of PTSD. The study aims, second, to examine the effects of intervention for one month using a leaflet to promote the morning-typed life for persons who suffered natural disaster entitled “Go to bed early, Get up early and Do not forget to have a breakfast for getting three benefits!”. Only one person was over the cutoff point (between 24 and 25) before intervention. This high-traumatic person’s comprehensive sleep health tended to be improved through the intervention (p = 0.052).

A questionnaire study and an intervention one were performed in this study. An integrated questionnaire was administered, in July 2014 to 1112 participants attending one of 10 nursery school and 1 kindergarten located in Kochi (33°N, 133°E), Japan, and 582 parents (mostly mothers) which answered it instead of children (rate of answer: 51.9%). Intervention was done to 111 children attending the kindergarten. Seventy six parents answered the questionnaire which was administered 3 months after the intervention days of 21 (rate of answer: 51.9%). There are two contents of intervention, one is the distribution of cows’ milk for 21 days to be drunk at breakfast and another is the distribution of leaflet entitled “Go to bed early! Get up early! and Take nutritionally rich breakfast and cows’ milk!” just before the intervention. Just before the intervention, letter was distributed to 111 parents who were asked for their children to follow the contents of the leaflet and drink the cows’ milk distributed every day for the 21 days. Small children who drink cows’ milk at breakfast more than once per week and take nutritionally rich breakfast more than 4 times per week are more morning-typed than the other three groups in which children fit into one or none of the two issues of taking morning cows’ milk and rich breakfast (p p = 0.004). Also there was positive correlation between the implementation value for the 21 days and the diurnal type score 3 months later (r = 0.301, p = 0.018). Drinking cows’ milk at breakfast seems to be effective for small children to become more morning-typed through two sets of syntheses from tryptophan via serotonin into melatonin in the evening.展开更多
