Abstract
A cross sectional analytic design was conducted on all male police officers who were on duty not less than 2 years in Ismailh’a governorate , and above the age of 30 years to study the prevalence of CHD among police officers in Ismaillia governorate with a comparable group of highly educated employees in Ismaillia. (Total number of police officers included in the study was 208)
All those included in the sample were subjected to clinical examination with special care to age, occupation, smoking history, family history of CHD, weight and height, blood pressure, and cardiac examination. Every subject in the study group was subjected for a planned questionnaire for detection of angina pectoris and myocardial infarction, type A self rating inventory and a planned questionnaire for detection of job stress. A resting ECG was done for all subjects and stress ECG was done for those with possible or probable ECG changes and negative questionnaire results for detection of CHD. Blood analysis was done for fasting blood sugar if there was no clear history of DM, total serum cholesterol, HDL, LDL and triglycerides for each subject. Collected data were analyzed, and a battery of appropriate significance tests were done.
The prevalence of CHD among police officers was 8..17%, whereas the prevalence among the age matched employees was 3.4% and the difference was significant. The mean age of ischaemic police officers was insignificantly lower than that of ischaemic employees.
Smoking was more prevalent among the police officers (51.4%) than that among the employees (49%) but the difference was non-significant. In addition, the mean value of smoking vigor expressed in package per year of the ischaemic police officers was higher than that of the ischaemic employees and the difference was significant. Furthermore, smoking was significantly related to CHD in both the police officers and the employees.
A positive family history for CHD was reported by 35.3% of the ischaemic group of police officers in comparison to 2.6% of the non ischaemic group and the difference was highly significant. Also, positive family history for CHD was reported by 71.4% of the ischaemic group of employees in comparison to 5.5% of the non ischaemic group and the difference was highly significant.
