Abstract

Objectives:

Natural disasters affect long-term health by directly disrupting or destroying health-care systems and social support. We examined the associations between social support and subjective symptoms (SS) among disaster victims living in their homes approximately 1–2 years after the Great East Japan Earthquake and tsunami on March 11, 2011, which devastated the northeastern Japan seaboard and far inland, focusing on Ishinomaki, Miyagi Prefecture.

Methods:

The Health and Life Revival Council of Ishinomaki District conducted door-to-door household surveys between April 2012 and January 2013. Replies to 12 questions regarding social support, specifically emotional, informational, and instrumental, were investigated. SS prevalence was calculated as the proportion of those having any of 8 predetermined symptoms including back pain, neck stiffness, sleep difficulty, dizziness, heart palpitations, poor appetite, or stomachache. Logistic regression analysis by sex was used to obtain crude and adjusted odds ratios for the association between SS prevalence and forms of social support.

Results:

From 4023 households, self-reported data on 2593 individuals from 1709 households were obtained. SS prevalence was 29.1%. Adjusted logistic regression analysis revealed that instrumental support with others and emotional support with personal and others were specific associated with SS in men and women, respectively.

Conclusions:

Our findings suggest that providing social support depending on needs is potentially effective in preventing SS in disaster areas.
