Little attention has been paid to whether temperature is associated with suicide and to whether suicide seasonality appears in Asian countries as shown in Western countries, even though suicide rates in Korea have increased steadily. The goal of the present study was to examine the association between daily temperature and daily suicide rate in Korea, taking gender, age, and education level into account. Data were analyzed using a generalized additive model, adjusting for confounding factors such as sunshine, relative humidity, holidays, and long-term trends. Suicide rates were higher in spring and summer than other seasons. We observed a 1.4% increase (95% confidence interval=1.0-1.7%) in suicide with each 1°C-increase in daily mean temperature. The suicide risks related to the temperature for males, elderly people, and those with less education were higher than for females, younger people, and those with more education, respectively. These findings have confirmed that temperature is associated with suicide in Korea and further our understanding of more susceptible groups, the effects of gender, age, and education level. Therefore, temperature, one of the meteorological factors, is an important risk factor on suicide.

Previous studies have indicated that suicide rates have significant seasonal variations. There is seasonal discordance between temperature and solar radiation due to the monsoon season in South Korea....
Urban areas are particularly vulnerable to heat-related health outcomes. Simultaneous trends of climate change and urbanization may increase the urban heat-related health burden. We investigated the e...
Less evidence concerning the association between ambient temperature and mortality is available in developing countries/regions, especially inland areas of China, and few previous studies have compare...
Studies on health effects of air pollution often use daily mean concentration to estimate exposure while ignoring daily variations. This study examined the health effects of daily variation of PM2.5. ...
Introduction The incidence of thyroid cancer has increased worldwide. The country where the incidence has increased most is South Korea. The goal of this study is to understand the magnitude of associ...
This study will evaluate the effectiveness of an individually tailored suicide prevention treatment program called SAFETY in reducing suicide and suicide attempts in adolescents.
Experimental studies and previous clinical trials suggest an improvement in mortality and neurological function with hypothermia after cardiac arrest. However, the accrued evidence is inco...
The literature is characterized by a dearth of information on interventions for homeless youth, and no suicide prevention intervention has been tested with these youth. Such focus is criti...
The purpose of this study is to examine the proposed suicide preventive effects of lithium in a randomized controlled trial within a group of individuals with depressive disorders. The hyp...
This research study is designed to answer specific questions about new ways to provide services for youth at-risk of suicide.
Former kingdom, located on Korea Peninsula between Sea of Japan and Yellow Sea on east coast of Asia. In 1948, the kingdom ceased and two independent countries were formed, divided by the 38th parallel.
The capital is Seoul. The country, established September 9, 1948, is located on the southern part of the Korean Peninsula. Its northern border is shared with the Democratic People's Republic of Korea.
Elimination of ENVIRONMENTAL POLLUTANTS; PESTICIDES and other waste using living organisms, usually involving intervention of environmental or sanitation engineers.
Insulated enclosures in which temperature, humidity, and other environmental conditions can be regulated at levels optimal for growth, hatching, reproduction, or metabolic reactions.
Removal of ENVIRONMENTAL POLLUTANTS or contaminants for the general protection of the environment. This is accomplished by various chemical, biological, and bulk movement methods, in conjunction with ENVIRONMENTAL MONITORING.
