Revising "Nutritional Reference Values for Feeding at Evacuation Shelters" According to Nutrition Assistance by Public Health Dietitians Based on Past Major Natural Disasters in Japan: A Qualitative Study

It is important to provide nutritionally adequate food in shelters to maintain the health of evacuees. Since the Great East Japan Earthquake in 2011, Japan’s Ministry of Health, Labour and Welfare has released the “Nutritional Reference Values for Evacuation Shelters” (Reference Values) after every major natural disaster. There is clear evidence, however, that the Reference Values have only been used infrequently. This study aims to revise these guidelines to include the actual situation in the affected areas and the feasibility of the endeavor. This qualitative study uses group interviews with local government dietitians to propose revisions to Japan’s Reference Values. These revisions include the following: issuing Reference Values within 1 week of a disaster, showing one type of values for meal planning for each age group, showing the minimum values of vitamins, upgrading salt to basic components, creating three phases of nutrition (Day 1, Days 1–3, and After Day 4), stipulating food amounts rather than nutrient values, and creating a manual. Local government officials could use the Reference Values as guidelines for choosing food reserves, and dietitians could use them while formulating supplementary nutrition strategies for a model menu in preparation for disasters.

Identifying nutritionally vulnerable groups in case of emergencies: experience from the Athens 1999 earthquake

During emergency situations in developing countries, young children have been identified as the most nutritionally vulnerable group. Comparatively less is known regarding nutritional risk of individuals in well-nourished societies hit by a major disaster. The aim of the present study, therefore, was to assess the nutritional status of Greek people who were left homeless after the Athens 1999 earthquake. A total of 225 volunteers from two camps were surveyed for dietary intake information and surrogate measures of nutritional status. Energy consumption and anthropometric indices of the children and adolescents revealed no sign of undernourishment. On the other hand, adults and the elderly consumed considerably less energy than that required for long-term preservation of health. Short-term energy and protein deficits, however, did not jeopardise their nutritional status as it might have expected, on the basis of high body mass indexes and normal haematological and biochemical profiles that were documented. In conclusion, the results of the present study indicate that nutritional risk in the acute phase after a major emergency in a previously well-nourished population is rather low. This is especially true for younger individuals, probably due to increased provision from the family and the community. Nevertheless, older persons may face increased risk as the situation is prolonged.

Public nutrition in complex emergencies

Public nutrition is a broad-based, problem-solving approach to addressing malnutrition in complex emergencies that combines analysis of nutritional risk and vulnerability with action-oriented strategies, including policies, programmes, and capacity development. This paper focuses on six broad areas: nutritional assessment, distribution of a general food ration, prevention and treatment of moderate malnutrition, treatment of severe malnutrition in children and adults, prevention and treatment of micronutrient deficiency diseases, and nutritional support for at-risk groups, including infants, pregnant and lactating women, elderly people, and people living with HIV. Learning and documenting good practice from previous emergencies, the promotion of good practice in current emergencies, and adherence to international standards and guidelines have contributed to establishing the field of public nutrition. However, many practical challenges reduce the effectiveness of nutritional interventions in complex emergencies, and important research and programmatic questions remain.

Lessons learned from complex emergencies over past decade

Major advances have been made during the past decade in the way the international community responds to the health and nutrition consequences of complex emergencies. The public health and clinical response to diseases of acute epidemic potential has improved, especially in camps. Case-fatality rates for severely malnourished children have plummeted because of better protocols and products. Renewed focus is required on the major causes of death in conflict-affected societies--particularly acute respiratory infections, diarrhoea, malaria, measles, neonatal causes, and malnutrition--outside camps and often across regions and even political boundaries. In emergencies in sub-Saharan Africa, particularly southern Africa, HIV/AIDS is also an important cause of morbidity and mortality. Stronger coordination, increased accountability, and a more strategic positioning of non-governmental organisations and UN agencies are crucial to achieving lower maternal and child morbidity and mortality rates in complex emergencies and therefore for reaching the UN's Millennium Development Goals.

Lessons on nutrition of displaced people

Policies for protecting the nutrition of displaced people (including refugees) have evolved significantly since the sharp increase in numbers began in the 1970s. Food supplies have often been grossly inadequate, probably contributing to the very high mortality rates and severe malnutrition observed in camps. These are related, in part, to low estimates of food energy needs, moving from the idea of "survival" rations (1200-1800 kcal/person/day) through "minimum" (1900 kcal) to a current target level, likely to be usually adequate, of 2100 kcal. Some donors aim to provide 2400 kcal to preclude the need for supplementary feeding. Micronutrient needs in food supplies have received less attention, despite reemerging epidemics of micronutrient deficiencies (e.g., scurvy, pellagra) in camp populations. Supplied commodity baskets are still not routinely designed to meet micronutrient needs. The relative roles of different feeding programs need clarification; therapeutic feeding in severe malnutrition is well established, although experience of supplementary feeding is mixed. Better information on nutrition, health and survival is now routinely available; in particular, using trigger levels of mortality rates (e.g., 1/10,000/day as a crisis) has helped enhance action. The existence of severe wasting in children is highly predictive of increased mortality and could be tested as a readily observed indicator. Overall, procedures for alleviating and preventing malnutrition have indeed improved, but much more slowly than the scientific basis could allow. A general conclusion is that learning lessons and applying them more quickly could still prevent much malnutrition and save many lives among displaced people.
