[0018] Using the results of published articles and the data of a city in northern my country as an example to illustrate the application effect of this method:
[0019] (1) Analytical method for each increase of 10 μg / m3--an example of the results of other people who have published articles:
[0020] ① On the day of exposure, PM 2.5 For every 10 μg / m3 increase in cardiovascular disease admissions, the number of patients admitted to the hospital increased by 2.12%, and the 95% credible limit was 1.42-2.82%;
[0021] ② On the day of exposure, PM 2.5 For every 10 μg / m3 increase in cardiovascular disease, myocardial infarction patients increased by 2.5%, and the 95% credible limit was 1.5-3.6%.
[0022] (2) Analysis method for every 10 micrograms / cubic meter increase -- based on the PM in a certain city in a certain year in my country 2.5 Data as an example:
[0023] Exposure day: PM 2.5 For every 10 μg / m3 increase, the number of cardiovascular disease outpatient visits incre...

The invention discloses a least squares mean square method for the acute health influence analysis of atmospheric pollutants. According to the least squares mean square method, a confounding factor influence-corrected corrected mean is adopted for evaluating the acute health influence, namely the average change amount of the number of patients, under the effects of different concentrations of pollutants. On the above basis, the percentage of the added amount is calculated. By adopting the least squares mean square method, firstly, the average numbers of patients at different concentration gradients of pollutants are calculated. Secondly, the percentage of the added amount is obtained. The method is logical in analysis, and the result of the method is visual and easy to understand. Meanwhile, the method is practical and convenient. The degree of the acute health influence at different concentration gradients of atmospheric pollutants can be conveniently recognized. An exposure-reactionrelation at different concentration gradients is obtained, and the obtained exposure-reaction relation provides a scientific basis for related departments to formulate haze prevention measures.
Description
technical field [0001] The invention relates to the technical field of public health and preventive medicine, in particular to a least squares mean method for analyzing the acute health effects of air pollutants. Background technique [0002] The analysis method for the acute health effects of air pollutants used in the published article only calculates the percentage increase in outpatient visits for every 10 μg / m3 increase in pollutants, that is, there is only one concentration and one percentage, and there is no average number of visits and more concentrations to compare. Contents of the invention [0003] The object of the present invention is to provide the least squares mean method of air pollutant acute health impact analysis, to solve the problem that raises in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical scheme: the least squares mean method of air pollutant acute ...
