ABSTRACT

Study objectives: This study aimed to investigate the role of social factors, especially social support for sleep, among victims living at home around 1-2 years after the Great East Japan Earthquake and tsunami.

Design: A cross-sectional household survey was conducted between May and December 2012 (14-21 months after the disaster) in the Ishinomaki area, Japan. Univariate and multivariate logistic regression models were used to examine the association between social factors, including social support, and prolonged sleep difficulties (persisting over 1 month). Social support was divided into three functions: emotional, informational, and instrumental support.

Participants: Data were obtained on 2,593 individuals who were living at home after the disaster.

Results: The prevalence of prolonged sleep difficulties was 6.9% (5.8% male, 7.7% female). This study showed that lack of social support has a stronger association with prolonged sleep difficulties than non-modifiable or hardly modifiable consequences caused directly by the disaster, i.e., severity of home damage, change in family structure and income. Among the three dimensions of social support, lack of emotional support showed the strongest association with prolonged sleep difficulties.

Conclusions: Social support, especially emotional support, may positively affect sleep among victims living at home around 1-2 years after a disaster.

Mentions: The data from the second phase of the survey were used for the present study. Fig 1. shows the flow of the participants through this study. We visited 13,137 households and were able to contact people in 8,021; in the other 5,116 households, no one was at home at the time of the visit. Among the 8,021 households, individuals from 4,032 households (11,430 eligible subjects) responded to the survey, and 2,593 individuals from 1,709 households responded to the third step of the survey. Of those 2,593 subjects, we excluded 130 who were aged 18 years or under because they were not ineligible for the third step of the survey; thus, the data on 2,463 household members were used for our analysis.
