OBJECTIVE Dyslipidemias, primarily hypercholesterolemia, are independent and strong predictors of cardiovascular (CV) events. The frequency of dyslipidemia is very important in terms of determining CV prevention policies. In order to determine the up-to-date frequency of CV risk factors in Turkey, a meta-analysis of the epidemiologic studies carried out in the last 15 years was performed. This article presents the results on the dyslipidemia data including hypercholesterolemia principally.
METHODS Epidemiological studies conducted during the last 15 years that have a potential to reflect Turkeys census sampling were searched in databases (Ovid Medline, Web of Science Core Collection, and Turkish Academic Network and Information Center [ULAKBIM]) and web pages (Ministry of Health, Turkey Statistical Institute, Turkish Society of Cardiology, Nephrology and Endocrinology Associations). A total of 7 studies including lipid data were found. Systematic review and meta-analysis of the studies with low bias score were performed. Crude values of the prevalence of hypercholeterolemia, hypertriglyceridemia and low HDL and mean lipid levels were calculated. Random effects model was used in meta-analysis.
RESULTS The prevalence of hypercholesterolemia defined as the LDL-cholesterol >130 and/or ≥130 mg/dL, was 29.1% (95% CI 23.635.0) in the general population, 30.2% in females (%95 CI 24.736.1), and 27.8% in males (95% CI 22.333.6). The prevalence of low HDL-cholesterol (≤50 mg/dL for females and ≤40 mg/dL for males) was calculated as 46.1% (95% CI 42.449.9) in the whole group, 50.7% (95% CI 47.753.6) in females and 41.1% (95% CI 36.146.3) in males. The prevalence of hypertriglyceridemia (>150 mg/dL) was 36.5% (95% CI 30.642.5) in general, 32.0% (95% GA 26.637.8) in females and 41.3% (95% CI 34.947.8) in males.
CONCLUSION Dyslipidemia constitutes a major public health problem in Turkey. In the adult population, almost 3 of 10 have hypercholesterolemia, one of 2 has a low HDL-cholesterol, and 1 of 3 has high triglycerides levels.
