Abstract

Data were collected and analyzed from a cross-sectional study using the World Health Organization’s STEPwise approach, to estimate the prevalence of various types of dyslipidemia and determine their associated factors among adults in Kingdom of Saudi Arabia. The study population included 4490 Saudi adults aged 15 years and older who were selected by a stratified, multistage, cluster random sampling technique. Lipid profile was determined by spectrophotometrically by biochemical methods, high total cholesterol (TC) was defined as TC of 5.2 mmol/L or more, hypertriglyceridemia as serum triglycerides level 1.7 mmol/L or more and. low high-density lipoprotein cholesterol (HDL-C) as serum HDL-C 0.9 mmol/L or less, LDL-C 3.35 mmol/L or more and TC/HDL ratio 5 or more. Of the 4490 subjects (94.4 % of total sample) included in the final analysis, 51% were females, 23% of study subjects were less than 25years and 11% were 55 or more years of age. The overall prevalence of dyslipidemia ranged from about 20% to 40%. The highest prevalence was for triglycerides where about 44% of all subjects were affected. About a fifth of the subjects had high level of total cholesterol. Males had significantly higher prevalence of all types of dyslipidemia than female except LDL-C and TC. Higher dyslipidemia prevalence of total cholesterol and triglycerides were significantly found in older subjects, illiterates and housekeepers. Lower prevalence rates for HDL-C was significantly observed in retired and youngest subjects. There were significant regional variations and significantly higher prevalence of dyslipidemia among hypertensives, diabetics, obese/overweight, smokers and physically inactive subjects. There were no significant differences according to income or fruits and vegetable consumption. Logistic regression analysis revealed that obesity/overweight, gender, age, diabetes were the most important significant predictors of dyslipidemia. The findings of this study suggest that the prevalence of dyslipidemia is high in Saudi Arabia. Multisectorial intervention strategies are needed targeting the predictors and significant risk factors identified.
