comparative study of lipoproteins, apolipoprotein A-I and B and lipoprotein [A] between Egyptian males and females in different age groups

Eighty normolipidemic healthy normal persons aged 25-65 years were chosen and divided into two groups, a male group [n=40] and a female group [n=40]. Each group was subdivided according to age into four subgroups: Group 1 [>25-35 years], group 2 [>35-45 years], group 3 [>45-55 years] and group 4 [>55-65 years]. For all cases, total cholesterol [TC], low-density lipoprotein [LDLc], high-density lipoprotein [HDLc], triglycerides [TG], apolipoproteins A-1 and B [Apo-A-1 and Apo-B] and lipoprotein [a] [Lp[a]] were measured. It was concluded that age and sex dependent reference normal range is important when assessing atherosclerotic risk by lipoprotein assay and it must be followed, better for each community separately
