Background: Study on the medium- to long-term effect of a great earthquake on health among the victims is limited. The purpose of the present study was to investigate the medium-term (i.e., three months) effect of the Great East Japan Earthquake (occurred on March 11, 2011) on health conditions (i.e., blood pressure, hemoglobin A1c [HbA1c], blood sugar, triglyceride, and total cholesterol) among the victims, by comparing with the control population.

Methods: In June 2011, taking blood pressure and blood tests were conducted for a total of 159 victims who had stayed in the shelter located in the Tohoku region since the Great East Japan Earthquake. The same tests were conducted for a total of 1,048 control participants in Tokyo from October 2010 to December 2011. Analyses of covariance and multiple logistic regression analyses were conducted.

Results: Compared with the control group, the victim group had significantly higher systolic and diastolic blood pressure; lower HbA1c, blood sugar, triglyceride, and total cholesterol, after adjusting for age and sex. In a similar way, the victim group had a significantly higher prevalence odds ratio of hypertension; lower prevalence odds ratios of diabetes mellitus, high blood sugar, high triglyceride, and high total cholesterol than control group.

Conclusions: The present study revealed that the prevalence of hypertension is higher among the victims of the Great East Japan Earthquake. Lower prevalence of diabetes mellitus, high blood sugar, high triglyceride, and high total cholesterol among the victims may be explained by the continued inadequate diet issues after the earthquake.
