Acute effects of diurnal temperature range on mortality in 8 Chinese cities

Impact of diurnal temperature range on mortality in a high plateau area in southwest China: A time series analysis

“…The effect of DTR on mortality has been studied in low altitude regions with low DTR (Holopainen et al, 2013;Lim et al, 2012;Yang et al, 2013;Zhou et al, 2014), but the effect of high DTR on mortality has been little studied (Luo et al, 2013;Vutcovici et al, 2014). To our knowledge, this is the first attempt to explore the effect of DTR on non-accidental, cardiorespiratory, cardiovascular and respiratory mortality in a high-altitude city in southwest China with a large range in daily temperature.…”

“…In recent years, diurnal temperature range (DTR) has been suggested as a predictor of mortality and found an independent risk factor for human health by an increasing number of epidemiological studies (Kan et al, 2007;Song et al, 2008;Yang et al, 2013). Calculated as the daily maximum temperature minus the daily minimum temperature within 1 day, DTR is an important meteorological indicator associated with global climate change and urbanization that reflects the stability of weather (Cheng et al, 2014;Xu et al, 2014;Zhou et al, 2014).…”

“…The effect of DTR on mortality has been explored in China (Kan et al, 2007;Song et al, 2008;Zhou et al, 2014), Korea (Lim et al, 2013;Lim et al, 2012), Finland (Holopainen et al, 2013) and Canada (Vutcovici et al, 2014). However, most of the cities under study were highincome and located in low-altitude regions or coastal areas with low DTR.…”

Temperature as a modifier of the effects of fine particulate matter on acute mortality in Hong Kong

“…Multicity studies have provided clear and convincing evidence that exposure to both hot and cold temperature was associated with increased risks of morbidity and mortality (Curriero et al, 2002;Ma et al, 2014). The independent effect of temperature on mortality has been extensively reported (Anderson and Bell, 2009;Xu et al, 2013;Zhou et al, 2014), but only a few studies have examined the effects of temperature modification on PM-associated mortality. Most of these studies identified significant interaction between PM and temperature (P<0.05), with stronger health effects of PM in high temperature days for all natural (Qian et al, 2008;Ren and Tong, 2006), and cardiovascular mortality (Li et al, 2011).…”

Compensatory growth in Microcystis aeruginosa after moderate high-temperature exposure

“…Although, sudden shifts of temperature are rare in natural conditions, temperature fluctuations between day and night can be great (Lauritsen and Rogers, 2012;Zhou et al, 2014). In the day time during summer, surface water temperatures can reach 35°C in Southern China, Southeastern North America, Middle East and other sub-tropical areas (meteorological data available from LTER Network Data Portal, https://portal.lternet.edu/nis/mapbrowse?packageid=knb-lter-ntl.10001.3).…”
