Disaster-related trauma and blood pressure among young children: a follow-up study after Great East Japan earthquake

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.

Cardiovascular Diseases in Natural Disasters; a Systematic Review

Introduction:

As a result of destruction and lack of access to vital infrastructures and mental stress, disasters intensify cardiovascular diseases (CVDs) and hence management of CVDs becomes more challenging. The aim of this study is investigating incidence and prevalence of CVDs, morbidity and mortality of CVDs, treatment and management of CVDs at the time of natural disasters.

Methods:

In the present systematic review, the articles published in English language until 28. 11. 2020, which studied CVDs in natural disasters were included. The inclusion criteria were CVDs such as myocardial infarction (MI), acute coronary syndrome (ACS), hypertension (HTN), pulmonary edema, and heart failure (HF) in natural disasters such as earthquake, flood, storm, hurricane, cyclone, typhoon, and tornado.

Result:

The search led to accessing 4426 non-duplicate records. Finally, the data of 104 articles were included in quality appraisal. We managed to find 4, 21 and 79 full text articles, which considered cardiovascular diseases at the time of flood, storm, and earthquake, respectively.

Conclusion:

Prevalence of CVD increases after disasters. Lack of access to medication or lack of medication adjustment, losing home blood pressure monitor as a result of destruction and physical and mental stress after disasters are of the most significant challenges of controlling and managing CVDs. By means of quick establishment of health clinics, quick access to appropriate diagnosis and treatment, providing and access to medication, self-management, and self-care incentives along with appropriate medication and non-medication measures to control stress, we can better manage and control cardiovascular diseases, particularly hypertension.

Five-year blood pressure trajectories of survivors of the tsunami following the Great East Japan Earthquake in Iwate

Whether tsunami survivors who suffered substantial damage experienced increases in blood pressure (BP) immediately after the disaster and in the medium to long term is unclear. We divided tsunami survivors into groups, those who relocated (substantial damage) and those who did not (little damage) and compared the BP trajectories between the groups over the first 5 years after the disaster. Of the 42,831 residents, 3914 were assessed from 2010 to 2015. Subgroup analysis was performed among the 2037 subjects with no information on antihypertensive medications between 2010 and 2015 (no antihypertensive medication group). The BP trajectories in the relocation and no relocation groups were compared using linear mixed models. The multivariate-adjusted mean systolic BP (SBP) values for all subjects significantly decreased after the disaster in both the group who relocated (2010: 130.6 mmHg, 2015: 124.8 mmHg) and the group who did not relocate (2010: 130.7 mmHg, 2015: 126.7 mmHg). The interaction between relocation and time points on SBP was significant (P = 0.017). In the no antihypertensive medication group, the SBP values in the subgroup who relocated were significantly lower in the second, third, and fifth years after the disaster than those in the subgroup who did not relocate. It was concluded that the SBP values of survivors of the tsunami caused by Great East Japan Earthquake decreased in the medium to long term after the disaster, and the group who relocated had a larger decrease in SBP than the group who did not relocate.
