The Relationship Between Temperature and the Incidence of Acute Coronary Events in Beijing a Time Series Approach / 环境与健康杂志

ABSTRACT

Objective To observe the relationship between temperature and the incidence of acute coronary heart disease. Methods After controlling long time trend season and other confounding factors the relationship between temperature and incidence rate of acute coronary heart disease was explored by using generalized additive models GAMs and the relationship between temperature and acute coronary heart disease specified by age gender disease history was also explored. Results The incidence of acute coronary heart disease began to be higher than the baseline as weekly average temperature was lower than 6 ℃ and it increased with the weekly average temperature decreasing. The relationship between weekly average temperature and the incidence of acute coronary heart disease was found similar among different population groups but relative risk and dangerous temperature range were different. Conclusion Low temperature cold easily induces the acute coronary heart disease in males aged over 65 years or with history of acute coronary heart disease.
