Abstract
Objectives: The impact of climate change on the health has been of increasing concern due to a recent temperature increase and weather abnormality, and the research results of the impact varied depending on regions. We synthesized risk estimates of the overall health effects of low and high temperature taking account of the heterogeneity. Methods: A comprehensive literature search was conducted using PUBMED to identify journal articles of low and/or high temperature effects on mortality. The search was limited to the English language and epidemiological studies using time-series analysis and/or case-crossover design. Random-effect models in meta analysis were used to estimate the percent increase in mortality with 1 o C temperature decrease or increase with 95% confidence intervals (CI) in cold or hot days. Results: Twenty three studies were presented in two tables: 1) low temperature effects; 2) high temperature effects on mortality. The combined effects of low and high temperatures on total mortality were 2% (95% CI, 1-4%) per 1 o C decrease and 4% (95% CI, 2-5%) per 1 o C increase of temperature, respectively. Conclusions: This meta analysis found that both low and high temperatures affected mortality, and the magnitude of high temperature appeared to be stronger than that of low temperature. I. 서 론 최근의 기상이변으로 인하여 언론매체 뿐 아니라 학계에서도 기후변화에 대한 관심이 커지고 있다. 특 히 기상이변 혹은 기온이변으로 인한 건강영향에 대 한 연구들이 많이 발표되고 있다. 기후변화로 인한 직접적인 영향에는 고온, 저온, 혹은 일교차 등에 의 한 건강영향이 있으며, 간접적인 영향으로는 기온상 승으로 인한 전염성 질환의 증가, 각종 재해로 의한 피해의 증가, 후진국에서의 식량문제 등이 있다. 1) 이 연구에서는 기온의 변화에 따라 사망에 미치는 영향 을 중심으로 살펴보고자 한다. 기후변화를 야기하는 원인은 다양하지만 그중 주 목받고 있는 것은 엘니뇨 현상이다. 2) 엘니뇨 현상은 †
