Objectives To assess the improvement of the menus by the meal providing system in emergency shelters, we reanalyzed the data obtained from the dietary survey at emergency shelters in the Miyagi Prefecture one month after the Great East Japan Earthquake in 2011.Methods We performed secondary use of the dietary survey conducted by the Miyagi prefectural government. In total, 386 emergency shelters participated in the dietary survey of one day in April 2011. We examined the meal providing system (the frequency of meals per day, the frequency of mass feeding for evacuees per day, and menu creators) and the menus at each emergency shelter (260). We classified menus into the following five groups: staple foods, main dishes, side dishes, dairy products, and fruits, and calculated the frequency of provision per day.Results There was no emergency shelter that provided zero or one meal per day. Compared with the emergency shelters that provided two meals per day, shelters that provided three had a significantly higher provision frequency of staple foods. However, there were no significant differences in the provision frequencies of the other four food groups between the shelters with two or three meals per day. In emergency shelters with a higher frequency of mass feeding for evacuees, the provision frequency of four food groups (staple foods, main dishes, side dishes, and fruits) was significantly higher compared to shelter with a lower frequency of mass feeding for evacuees. Furthermore, in the emergency shelters where dietitians created menus, the provision frequency for two food groups (dairy products and fruits) was significantly higher compared to shelters without dietitians.Conclusion A high frequency of mass feeding for evacuees resulted in a high provision frequency of main dishes, side dishes, and fruits, which can be limited in supply after a disaster. Also, in the emergency shelters where dietitians created menus, the provision frequency of dairy products and fruits was higher than in those without dietitians. These results suggested that diets in the emergency shelters may be improved by mass feeding and the involvement of dietitians. |
