“…To be able to formulate comprehensive heat-health action plans, it is imperative that we assess heat-related health risks in rural areas [14]; however, conducting risk assessments for rural settings can be challenging. Most rural areas, especially in underdeveloped countries, lack meteorological data due to a paucity of weather monitoring stations [15,16]. Additionally, relatively small rural populations militate against epidemiologic studies with sufficient statistical power.…”

Most epidemiological studies of high temperature effects on mortality have focused on urban settings, while heat-related health risks in rural areas remain underexplored. To date there has been no meta-analysis of epidemiologic literature concerning heat-related mortality in rural settings. This study aims to systematically review the current literature for assessing heat-related mortality risk among rural populations. We conducted a comprehensive literature search using PubMed, Web of Science, and Google Scholar to identify articles published up to April 2018. Key selection criteria included study location, health endpoints, and study design. Fourteen studies conducted in rural areas in seven countries on four continents met the selection criteria, and eleven were included in the meta-analysis. Using the random effects model, the pooled estimates of relative risks (RRs) for all-cause and cardiovascular mortality were 1.030 (95% CI: 1.013, 1.048) and 1.111 (95% CI: 1.045, 1.181) per 1 °C increase in daily mean temperature, respectively. We found excess risks in rural settings not to be smaller than risks in urban settings. Our results suggest that rural populations, like urban populations, are also vulnerable to heat-related mortality. Further evaluation of heat-related mortality among rural populations is warranted to develop public health interventions in rural communities.

“…numerous studies have reported associations between temperature and mortality as nonlinear (J-or U-shaped) relationships, highlighting the mortality effects of extreme cold or hot temperatures. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] although earlier research focused on a single city or a few cities, several time-series studies covering multiple cities or countries have recently been published. [1][2][3][4][5][6][12][13][14][15][16][17][18] Studies with multiple cities or countries allow for meaningful comparisons across geographic areas and for more accurate estimations of between-city or between-country variations, using a unified analytical framework.…”

“…Hashizume et al (2009) find that perinatal mortality sharply increases with low temperatures. Dadvand et al (2011) conclude that extreme heat was associated with a reduction in the average gestational age of children, which is associated with perinatal mortality and morbidity.…”

“…This effect is even larger in low-income areas. Hashizume et al (2009) characterize the daily temperature-mortality relationship in rural Bangladesh and find that for the period between 1994 and 2002, a 1°C decrease in mean temperature was associated with a 3.2 percent (95 percent confidence interval: 0.9-5.5) increase in mortality, with deaths resulting from perinatal causes sharply increasing with low temperatures. In an international study of temperature and weather in urban areas using data from 12 cities in developing countries, including Mexico City and Monterrey, McMichael et al (2008) find a U-shaped temperature-mortality relationship, with significant death rate increases at lower temperatures.…”

Using data for all 2,454 municipalities of Mexico for the period 1980-2010, this paper analyzes the relationship between exposure to extreme temperatures and precipitation and death, as well as the relationship between severe weather and agricultural income and crop production in the country. It is found that extreme heat increases mortality, while the health effect of extreme cold is generally trivial. Precipitation extremes seem to affect the agricultural system, but their impact on mortality is ambiguous. More specifically, exchanging one day with a temperature of 16-18 °C for one day with temperatures higher than 30 °C increases the crude mortality rate by 0.15 percentage points, a result robust to several model specifications. It is also found that the extreme heat effect on death is significantly more acute in rural regions, leading to increases of up to 0.2 percentage points vis-à-vis a 0.07-point increase in urban areas. The timing of climate extremes is relevant: if a weather shock takes place during the agricultural growing season, the effects on mortality and agricultural output, productivity, prices, and crop yields are large and significant, but not so if such shocks occur during the non-growing season.
