全球95%以上的烧伤死亡发生在低收入和中等收入国家。然而，烧伤死亡率与经济健康之间的关系尚未在个别国家进行评估。本研究旨在回答这个问题，烧伤死亡率和国家经济实力指数之间的相关性有多强？研究方法：在2008-2010年期间，使用世界银行的经济数据以及世界卫生组织（世卫组织）的死亡率数据对189个国家进行了回顾性审查。世界银行根据收入水平将各国分为四组：低收入、中低收入、中高收入和高收入。皮尔森相关系数用于估计死亡率之间的关联存在和强度，基尼系数（衡量财富分配不平等）、人均国内生产总值（国内总产值）和人均国民总收入指数。统计学显著相关性烧伤死亡率与人均GDP之间有显著性差异（p < 0.05（r = -0.26），人均国民总收入（r = -0.36），基尼系数结论：一个国家的收入水平与烧伤死亡率呈负相关，收入水平越低，烧伤死亡率越高。一个国家的收入分配公平或不公平的程度也与烧伤死亡率相关。意义：政府和非政府组织都需要把重点放在预防低收入国家以及其他收入差距明显的国家的烧伤上。(C)2013 Elsevier Ltd和ISBI。All rights reserved.
Introduction: Over 95% of burn deaths occur in low- and middle-income countries globally. However, the association between burn mortality rates and economic health has not been evaluated for individual countries. This study seeks to answer the question, how strong is the correlation between burn mortality and national indices of economic strength?Methods: A retrospective review was performed for 189 countries during 2008-2010 using economic data from the World Bank as well as mortality data from the World Health Organization (WHO). Countries were categorized into four groups based on income level according to stratification by the World Bank: low income, lower middle income, upper middle income, and high income. The Pearson correlation coefficient was used to estimate presence and strength of association among death rates, Gini coefficient (measure of inequality of distribution of wealth), gross domestic product (GDP) per capita, and gross national index (GNI) per capita.Results: Statistically significant associations (p < 0.05) were found between burn mortality and GDP per capita (r = -0.26), GNI per capita (r = -0.36), and Gini (r = +0.17).Conclusions: A nation's income level is negatively correlated with burn mortality; the lower the income level, the higher the burn mortality rates. The degree to which income within a country is equitably or inequitably distributed also correlates with burn mortality.Significance: Both governmental and non-governmental organizations need to focus on preventing burns in low-income countries, as well as in other countries in which there is marked disparity of income.
