Awareness of atherosclerosis risk factors in Nigeria

Abstract

Non-communicable diseases, which include hypertension and diabetes mellitus, have become an important cause of morbidity and mortality in Nigeria. The determination of serum lipid levels is used routinely to assess the risk of atherosclerosis. This study was performed in order to determine the frequency of serum lipid requests in the community. Information on both lipid and total chemical pathology requests for the study period (May 1998 to April 2000) was obtained from the Department of Chemical Pathology, University of Ilorin Teaching Hospital, whilst data on the total hospital attendance was obtained from the hospital’s Record Department. The number of serum lipid requests increased from year to year (May 1998 to April 1999 = 780; May 1999 to April 2000 = 1,357; May 2000 to April 2001 = 1,382). The percentages of total requests for serum lipids when compared with the total laboratory requests for the period of study were 12.0%, 13.3% and 14.0% for the first, second and third year respectively. More men than women had their serum lipid levels determined; 31.3% of the patients had hyper-cholesterolaemia (>5.2 mmol/L), while 9.9% had values >6.2 mmol/L. Industrial disputes (strikes) affected our results. For the three-year period there was no remarkable increase in the use of the lipid profile facilities available in the centre. This reflects the inadequate awareness of lipid disorders as a risk factor for atherosclerosis.
