A cross-sectional survey of blood pressure of a coastal city's resident victims of the 2011 Tohoku tsunami.

Background: Blood pressure (BP) increase as a reaction to major disasters has been well documented; however, the impact has been underdocumented for tsunamis. This study aimed to confirm whether different levels of flooding/inundation and other damage caused by the 2011 Tohoku (northeast Japan) tsunami were associated with BP among resident victims in Higashi-Matsushima, Miyagi.

Methods: Cross-sectional household screening was conducted 7-19 weeks after the disaster in administrative areas totally or partially flooded by the tsunami.
