This study examines how post-disaster meal provisions evolve with shelter size and over time to better support evacuees’ dietary needs.
Analysis was conducted on 96 dietary assessment sheets from the 2016 Kumamoto Earthquake, categorized by 3 shelter scales and time elapsed since the disaster. Differences in meal types and dish categories were compared using the Z test. Focus was placed on meal provision details and dietary considerations for vulnerable evacuees.
In the early stages, some shelters provided meals only twice daily. However, over time, boxed meals became more common, while the proportion of hot meal services decreased. Ready-to-eat foods-based meals predominantly consisted of “grain-based dishes” across all weeks and shelter sizes. Larger shelters tended to have fewer dietary considerations for vulnerable evacuees.
Continuous hot meal services may not be sustainable, suggesting a shift toward well-balanced boxed meals from vendors. Larger shelters faced challenges with unhealthy dietary behaviors and inadequate nutritional support for vulnerable evacuees. The findings can help municipalities develop concrete disaster nutrition plans considering disaster phase and shelter size.
