The Association Between Ambient Temperatures and Hospital Admissions Due to Respiratory Diseases in the Capital City of Vietnam

Abstract

This study aimed to examine the short-term effects of ambient temperature on hospital admissions due to respiratory diseases among Hanoi residents. We collected 34,653 hospital admissions for 365 days (November 1, 2017, to November 31, 2018) from two hospitals in Hanoi. A quasi-Poisson regression model with time series analysis was used to explore the temperature-health outcome relationship's overall pattern. The non-linear curve indicated the temperatures with the lowest risk range from 22 degrees (Celcius) to 25 degrees (Celcius). On average, cold temperatures showed a higher risk than hot temperatures across all genders and age groups. Hospital admissions risk was highest at 13 degrees (Celcius) (RR = 1.39; 95% CI = 1.26–1.54) for cold effects and at 33 degrees (Celcius) (RR = 1.21, 95% CI = 1.04–1.39) for the hot effects. Temporal pattern analysis showed that the most effect on respiratory diseases occurred at a lag of 0 days for hot effect and at a lag of 1 day for cold effect. The risk of changing temperature among women and people over 5 years old was higher than other groups. Our results suggest that the risk of respiratory admissions was greatest when the temperature was low. Public health prevention programs should be enhanced to improve public awareness about the health risks of temperature changes, especially respiratory diseases risked by low temperatures.

Climate change and human health in Vietnam: a systematic review and additional analyses on current impacts, future risk, and adaptation

“…For the cause-specific hospitalisations, high and low temperatures were associated with elevated risk of respiratory diseases 34 , 35 , 38 and cardiovascular diseases, 34 , 39 , 40 , 41 while high temperatures were linked to risk of infectious diseases, 33 , 34 , 35 , 42 , 43 kidney diseases, 44 and mental health disorders. 45 , 46 , 47 The vulnerable groups to heat-related health risks included older people, 31 , 32 , 35 , 39 , 48 children, 42 , 49 , 50 , 51 and those frequently working outdoors such as farmers and traffic police.…”

“…Respiratory infectious diseases including influenza/influenza-like, mumps, chickenpox, and tuberculosis were investigated in nine original studies 38 , 110 , 117 , 122 , 123 , 124 , 125 , 126 , 127 and one review. 94 These illustrated contradictory impacts of climatic factors on respiratory infectious diseases in different research settings.…”

The 2023 report of theMJA–LancetCountdown on health and climate change: sustainability needed in Australia's health care sector

“…The major climate-related health risks in Vietnam result from rising temperatures, extreme weather events, and climate-sensitive infectious diseases. Studies consistently demonstrate increased mortality, 95 and hospitalisation risks for climate-sensitive diseases due to rising temperatures (ie, respiratory diseases, [96][97][98] cardiovascular diseases, 96,[99][100][101] kidney diseases, 102 and mental health disorders [103][104][105] ). The vulnerable groups to heat-related health risks included older people, 95,97,99,106 children, [107][108] and those frequently working outdoors such as farmers and police.…”

City-scale assessment of long-term air quality impacts on the respiratory and cardiovascular health

“…We already managed to implement this approach in the city of Brno, where this assessment will be carried out over the next years in collaboration with the city hall. We will also include another predictors of urban exposome such as light pollution ( 78 ), meteorological conditions ( 79 ) or other socio-economic parameters. And while so far, we are limited in spatial resolution of ZAs, this limitation may be surpassed in the future, increasing the accuracy of the results.…”
