The atherogenic index of plasma is increased by hormonal contraception.

Background/aims: Oral contraceptives are known to induce secondary dyslipidemia. The aim of this study was to determine if hormonal contraceptives affect the new atherogenic index of plasma (AIP) = log[triglycerides (TG)/high-density lipoprotein cholesterol (HDL-C)] together with the total cholesterol/HDL-C (TC/HDL-C) and the apolipoprotein B/apolipoprotein A1 (apoB/apoA1) ratios.

Design And Methods: This study included 43 healthy women.
