Based on the epidemiological data, coronary heart disease (CHD) is one of the most prevalent disease and has caused high mortality all over the world. Recently, this disease has been appearing in larger and younger population, such as workers’ age. This research’s objective is to know the prevalence and risk factors for coronary CHD in mine workers.

Using a cross-sectional study in a population of mine workers from a mine company in Kalimantan. The secondary data is obtained from the workers’ medical check-up record on the year 2009. From simple random sampling,1651 samples are recruited.Samples are being analyzed using PASW version 18.

2009 CHD prevalence in mine workers is 1,2%, with ST elevation or depression as criteria for CHD diagnosis. The risk factors for CHD were hypertension, obesity, at-risk waist circumference (p<0,01), and occupation (p=0,01). Multivariate analysis was conducted and the main determinant factor of CHD was hypertension (p= 0,000; adjusted OR 5,64; 95%CI 2,15-14,81). Other determinant factors were waist circumference (p=0,007; adjusted OR=4,29; 95CI%=1,49-12,33) and occupation (p=0,018; adjusted OR=3,37; 95%CI=1,22-9,25).

Hypertension and waist circumference were known for their role in CHD pathophysiology by interfering the lipid metabolism, causing endothelial dysfunction, and changing the insulin sensitivity. They interact and lead to atherosclerosis, which accelerates the CHD proccess. Occupation was a determinant factor due to its correlation with physical inactivity in non-manual job. A proper education about these risk factors (plus their complications and management) to the mine workers can provide optimum prevention of CHD.
