Frontiers in Disaster Nutrition: Evidence to Action.

The need for food and nutrition assistance has increased due to the frequent occurrence of disasters and pandemics, such as coronavirus disease 2019 (COVID-19). However, after a disaster, food and nutrition are insufficient in terms of quantity and quality. In the case of the Great East Japan earthquake, the improvement factors for food and nutrition at emergency shelters included 1) emergency shelter size and equipment, 2) provision and content of meals, 3) collaboration among professionals, and 4) cooperation between shelters. However, there were hygiene and oral health problems, and dispatched dietitians had problems with nutrition assistance. The hygiene problems included 1) food, 2) cooking environment, 3) water supply and discharge, and 4) living space. In addition, oral health problems included 1) difficulty swallowing, 2) difficulty chewing, 3) environmental degradation, and 4) degradation of the oral condition. The problematic points of dispatched dietitians included the support provided not necessarily being consistent with needs, operational deficiencies at both the dispatching and receiving sides, and the short period of support. "Enthusiasm" can be a source of encouragement and a burden. To solve these problems, a training system for disaster dietitians and certification systems for disaster food have been established in Japan. Since the Great East Japan earthquake, various kinds of evidence and actions have been taken, and nutritional problems after disasters have gradually improved. Therefore, it seems that advanced actions and standards should be set not only in Japan but also globally.

Association between personality traits and food stockpiling for disaster.

This study investigated the association between personality traits and food stockpiling for disasters in predicted high-risk areas of food shortages due to the Nankai Trough Earthquake. This survey was conducted between December 18 and 20, 2019, using a web-based questionnaire. The participants were 1,200 individuals registered with an online survey company. This study analyzed the association between the Big Five personality traits and food stockpiling status (n = 1192). The Big Five personality traits assess five basic dimensions of personality (i.e., extraversion, conscientiousness, agreeableness, neuroticism, and openness). To measure theses personality traits, we used the Japanese version of the Ten-Item Personality Inventory (TIPI-J). The Mann-Whitney test and a multivariable logistic regression analysis revealed that none of the Big Five personality traits were significantly associated with having or not having stockpile food. However, interestingly, considering the stages of behavior change regarding stockpiling, high extraversion was significantly positively related to initiating stockpiling. Moreover, high neuroticism was significantly positively related to interrupted stockpiling. Therefore, it is crucial to focus on personality traits (especially low extraversion and high neuroticism) to promote food stockpiling for disasters.

Association between Lifestyle Changes and at-Home Hours during and after the State of Emergency Due to the COVID-19 Pandemic in Japan.

Lifestyle changes during the coronavirus disease (COVID-19) lockdown have been previously examined, but there is limited understanding about changes after such restrictions were lifted. This study examines changes in lifestyle habits and body weight among the Japanese population with regard to the length of at-home hours both during (April to May) and after (September) the nationwide stay-at-home request compared to those before the COVID-19 pandemic (January 2020). An online survey was conducted in September 2020 involving 10,000 Japanese survey monitors, selected according to population distribution. During the stay-at-home request, 34% participants extended their at-home hours. More respondents in the group with extended at-home hours experienced an increase or decrease in total physical activity, snacking, food intake, alcohol drinking, and body weight than those in the group with nonextended at-home hours. Some of these changes had a trend according to age. The prevalence of most of these changes decreased when at-home hours returned to normal after the stay-at-home request period; however, increased alcohol consumption and increased or decreased body weight persisted. Our findings suggest that close monitoring for further health outcomes and age-appropriate measures to encourage favorable health behaviors is needed.
