[Investigation of Factors Related to Stockpiling of Oral Care Hygiene Materials in Normal Times: Internet Survey Analysis].

Abstract

Objectives: The aim of this study was to clarify the current status of stockpiling of oral care hygiene materials in case of a disaster and to determine methods to support stockpiling during disaster preparation.

Methods: We conducted an Internet questionnaire survey on stockpiling and disaster prevention measures among 300 adults. For statistical analysis, the χ² test, Mann-Whitney U-test and Spearman rank test were employed. Logistic regression analysis was conducted to review factors related to stockpiling.

Results: Among the questions on stockpiling and disaster prevention (14 of 15 items), seven items on disaster prevention measures and two on disaster prevention experiences significantly differed. Analysis of disaster prevention knowledge revealed that disaster prevention measures and disaster experiences significantly differed in terms of the presence or absence of stockpiling, albeit a positive correlation was noted with stockpiling. Logistic regression analysis was conducted with stockpiling as a dependent variable. As a result, the items 'I am aware about the hazard map of the residential area', 'I am aware about the type of oral care hygiene materials prepared for emergency' and 'Devising the living environment such that large furnitures and cupboards do not collapse during disasters' were effective.

Conclusions: Stockpiling at home is considered necessary for self-sufficiency during a disaster on the basis of the experiences in disaster management, disaster prevention knowledge and disaster prevention measures. Hence, stockpiling is a strong measure against disaster prevention along with provision of appropriate knowledge about the necessity of oral care in daily life. Disaster prevention education that empowers a population to prepare itself by implementing disaster prevention measures, such as improving the home environment, is considered effective. In addition, considering that relying on stockpiling at an individual level is ineffective, it is necessary to create mechanisms and systems that jointly manage disaster situations according to local circumstances.
