Abstract

Coronary heart disease (CHD) is increasing in developing countries, particularly in urban areas. The impact of urbanization and apolipoprotein (apo) A-IV genetic polymorphism on plasma lipoproteins was studied in 222 men and 236 women from rural and urban Costa Rica. The apoA-IV allele frequencies were 0.937 for apoA-IV-1 and 0.062 for apoA-IV-2, Significant interactions between the apoA-IV polymorphism and area of residence (rural versus urban) were detected for HDL cholesterol (P = .003), apoA-I (P = .05), LDL particle size (P = .01), and LDL/HDL cholesterol ratio (P = .005). Urban compared with rural carriers of the apoA-IV-2 allele had significantly lower plasma HDL cholesterol (0.95 versus 1.17 mmol/L) and apoA-I (980 versus 1140 mg/L), a significantly higher LDL/HDL cholesterol ratio (3.35 versus 2.39), and significantly smaller LDL particles (258 versus 263 A). In contrast, no significant rural-urban differences for these parameters were found in apoA-IV-1 homozygotes. Regardless of their apoA-IV phenotype, urban residents consumed more saturated fat (P = .02) and smoked more cigarettes per day (P = .03) than rural residents. A significant interaction between saturated fat intake and apoA-IV phenotype was found for HDL c...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
