Associations Between Lifestyle Factors and Constipation Among Survivors After the Great East Japan Earthquake: A 9-year Follow-up Study.

Lifestyle factors, such as poor mental health, physical inactivity, and low frequency of meals were associated with constipation. Our findings suggest continuous support for the survivors with constipation for medium- to long-term after disasters.
