1972-1974年曾对三个市区工厂职工开展了冠心病的调查,了解了冠心病的患病率。为探求冠心病在市区工厂职工的发病情况并作随访,于1974-1977年复查了此三厂的职工,与1972-1974年调查资料进行对比分析。 资料的收集和处理 1972-1974年对市区三个工厂共检查职工2,923人,其中男1,636人、女1,287人。冠心病患者共133例,男53例,女80例。本次复查了原无冠心病者共2,373人,其中男1,290人、女1,083人。复查率男占76.65％、女占89.73％。漏查率男占23.35％、女占10.27％。漏查的原因是复杂的:有的调离了该厂,有的临时出差或离沪,有若干对象因为估计自己不致生冠心病而拒绝复查,还有少数已经死亡等。但对二次检查间隔内死亡的职工,都了解了死亡原因,凡非死于冠心病者一律剔除不计,而对第一次检查时非冠心病患者,但在第二次检查前死于冠心病者,仍加入复查人数中作为冠心病计算。
In 1972-1974, surveys of coronary heart disease were conducted among employees of three urban factories to understand the prevalence of coronary heart disease. In order to investigate the incidence of coronary heart disease in urban factory workers and follow up, the employees of the three plants were reviewed from 1974 to 1977, and compared with the survey data from 1972 to 1974. Data collection and processing A total of 2,923 employees were inspected in the three urban factories in 1972-1974, including 1,636 males and 1,287 females. A total of 133 patients with coronary heart disease, 53 males and 80 females. A total of 2,373 people with no coronary heart disease were reviewed, including 1,290 men and 1,083 women. The review rate is 76.65% for men and 89.73% for women. The males accounted for 23.35% of males and 10.27% of females. The reasons for the missed check are complex: Some are transferred from the factory, some are on a temporary business trip or leave Shanghai, and several objects are rejected because they are estimated to have no coronary heart disease, and a few have died. However, for the workers who died during the second inspection interval, they all understood the cause of death. All those who did not die of coronary heart disease were excluded, but those who did not have coronary heart disease at the time of the first examination, but died before the second examination. Those who have heart disease are still included in the number of reviews as coronary heart disease.
