ABSTRACT
The present study analysed the relationship between some environmental occupational stress Factors in terms of decision latitude, demand context, perceived strain during work and blood lipids as a risk factor of ischaemic heart disease [IHD], in terms of cholesterol, triglycerides, HDL-C, LDL-C, Apolipoprotein, A[I], Apolipoprotein B and lipoprotein [a]. The study was carried out in one of the factories in the tenth of Ramadan and included a cross sectional samples of 105 male workers aged 35-50 years, employed in jobs with regular mental tasks and a certain degree of responsibility for more than 10 years duration. The participants were interviewed and personal, occupational and medical data were collected and biochemical blood investigations were done. The study showed significant higher serum cholesterol in the group of disturbed relations at work. Serum levels of LDL-C was significantly higher in some groups of occupational stress, while serum HDL-C was significantly lower. Serum triglycerides was significantly increased in two groups. There was a significant association between lower serum levels apo-[I] and some of the occupational stress factors. Low decision latitude was the only stress factor which showed a significant correlation with high levels of lipoprotein [a]
