“…Our results are in line with some previous studies in Japan 15,16,21 and elsewhere. 14 A population-based study in Japan, 16 in the second-highest quintile was significantly lower (Q4: 0.80, 95% CI 0.69-0.94) for ischemic stroke. This association prevailed through the minimum and maximum temperatures.…”

2018, the population over the age of 65 years comprised nearly one-third (28.1%) of the total population. 9 Elderly people are more vulnerable to stroke due to change in hemodynamics. 10 Moreover, abrupt changes in temperature cause respiratory infections. 11 In earlier reports, a relationship between such infections and the occurrence of acute stroke was observed. 12 Regarding stroke, the effect of meteorological factors has studied both outside 8,13,14 and inside Japan. [15][16][17][18][19][20][21][22][23] The relationship between seasonal variation and stroke incidence, 15-17 and weekly variations of temperature on stroke onset 18 have been also studied. In particular for ambient temperature, hourly, 19,20 daily mean of maximum tempera-S troke is the second leading cause of death globally and was responsible for 11% of the 55.4 million global deaths in 2019. 1 Absolute numbers of stroke and burden by death and disability-adjusted life years lost show an increasing trend from 1990 through 2010. 2 In Japan, stroke is still one of the major causes of death 3 and morbidity. 4 Meteorological parameters affect human health, and studies have evaluated this relationship. 5,6 In particular, the effect of air pollution and atmospheric pressure, as well as temperature, on stroke. 7,8 Japan has 4 distinctive seasons with variations of temperature from day to day. In addition, elderly people are greater in number; as of October 1,

“…There are 11 inner-city areas in Zunyi: Laocheng (LC) Road, Wangli (WL) Road, Zhonghua (ZH) Road, Nanmenguan (NMG) Road, Yanan (YA) Road, Zhoushuiqiao (ZSQ) Road, Zhongshan (ZS) Road, Beijing (BJ) Road, Shanghai (SH) Road, Xima (XM) Road, and Dalian (DL) Road, covering a wide range of geographic areas in Zunyi city (105 km 2 ) and a total population of more than 110 million. These 11 inner-city areas are homogeneous in terms of lifestyle, education, employment and income, housing, geographical origin of the residents, and effects of air pollution ( 11 ).…”

Few studies evaluate the amount of particulate matter less than 2.5 mm in diameter (PM2.5) in relation to a change in lung function among adults in a population. The aim of this study was to assess the association of coal as a domestic energy source to pulmonary function in an adult population in inner-city areas of Zunyi city in China where coal use is common. In a cross-sectional study of 104 households, pulmonary function measurements were assessed and compared in 110 coal users and 121 non-coal users (≥18 years old) who were all nonsmokers. Several sociodemographic factors were assessed by questionnaire, and ventilatory function measurements including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), the FEV1/FVC ratio, and peak expiratory flow rate (PEFR) were compared between the 2 groups. The amount of PM2.5 was also measured in all residences. There was a significant increase in the relative concentration of PM2.5 in the indoor kitchens and living rooms of the coal-exposed group compared to the non-coal-exposed group. In multivariate analysis, current exposure to coal smoke was associated with a 31.7% decrease in FVC, a 42.0% decrease in FEV1, a 7.46% decrease in the FEV1/FVC ratio, and a 23.1% decrease in PEFR in adult residents. The slope of lung function decrease for Chinese adults is approximately a 2-L decrease in FVC, a 3-L decrease in FEV1, and an 8 L/s decrease in PEFR per count per minute of PM2.5 exposure. These results demonstrate the harmful effects of indoor air pollution from coal smoke on the lung function of adult residents and emphasize the need for public health efforts to decrease exposure to coal smoke.

“…Seasonal changes of temperature promote alterations in respiratory morbidity and in total and cause-specifi c mortality. Our previous study found that seasonal changes in Zunyi were associated with residents' respiratory [5,9] and cardiovascular morbidity [18], including asthma and asthma-related symptoms. Moreover, our exploratory study has revealed a linear relationship between respiratory outcomes and daily mean air temperature.…”

Weather and climate are known to infl uence human health. Seasonal changes of temperature promote alterations in respiratory morbidity and in total and cause-specifi c mortality. Data on the prevalence of asthma and asthma-related symptoms and its disparities between winter and summer in the acid rain-plagued city of Zunyi in southwestern China have not been widely available.In order to describe the epidemiology of asthma and asthma-related symptoms and its prevalence changes between winter and summer, we have completed two cross-sectional surveys of people aged ≥18 years in winter and summer in the inner-city areas of Zunyi city, Guizhou Province, China.The subjects were selected using a simple random sampling method. Data on asthma and asthma-related symptoms and selected home environmental factors were assessed by questionnaire.The studied Chinese adult population residing in Zunyi recorded a lower prevalence rate of asthma than those of Western countries. There was signifi cant difference in asthma prevalence among adult respondents between winter (1.8%) and summer (0.8%) in inner-city Zunyi. Asthma and asthma-related symptoms occurred more frequently in winter than summer, and that difference mainly correlated with environmental risk exposures, including coal combustion, frequency of stove cooking, fan or range hood usage, mattress material, pet possession, must and mould in the bedroom, etc.The prevalence of adult asthma and asthma-related symptoms was higher in winter compared to the summer in Zunyi, China. Our study suggests that asthma may be an important component of the public health burden of indoor air pollution, especially in winter.
