Introduction: The aim of this study was to evaluate the frequency of lipid profile requests and the prevalence of dyslipidemia in patients at the
biochemistry laboratory of St. Louis University Hospital, as well as their correlation with sex and age. Methods: This was a retrospective study
reviewing 14,116 laboratory results of patients of both sexes, over a period of six months (January-June 2013) regardless of the indication for the
request. The lipid parameters included were: Total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides with normal values defined as
follows: Total cholesterol (<2g/l), HDL- cholesterol (>0,40g/l), LDL- cholesterol (<1,30g/l) and Triglycerides (<1,50g/l). Results: The average age
of our study population was 55.15 years with a female predorminance (M/F=0.60). The age group most represented was that between 55-64
years. The frequency of lipid profile request in our sample was 9.41% (or 1,329). The overall prevalence of isolated hypercholesterolemia,
hyperLDLaemia, hypoHDLaemia, hypertriglyceridaemia, and mixed hyperlipidemia were respectively 60.91%, 66.27%, 26.58%, 4.57% and 2.75%.
Hypercholesterolemia, hyperLDLaemia, hypertriglyceridaemia and mixed hyperlipidaemia were higher in women with respectively 66.22%,
67.98%, 4.58%, 2.89% than in men (52.01%, 62.81%, 4.44% and 2.40% respectively). On the other hand, the prevalence of hypoHDLaemia was
higher in males (32.19%) compared to females (23.76%). Hypercholesterolemia correlated significantly with age and sex. Conclusion: Our study
showed a relatively low request rate for lipid profile and a high prevalence of dyslipidaemia hence the importance of conducting a major study on
the prevalence of dyslipidaemia and associated factors in the Senegalese population.
