Objectives

To determine the association of atherogenic index of plasma (AIP), the logarithm of molar ratio of triglyceridemia to high-density lipoprotein cholesterol (TG/HDL-cholesterol) with cardiometabolic disorders was investigated in a sample of the Turkish population.

Methods

A total of 2676 middle-aged adults were prospectively evaluated with a clinical examination and laboratory tests during 7.8 years' follow-up.

Results

AIP was significantly associated in multiple linear regression analyses with greater apolipoprotein B and lower low-density lipoprotein (LDL)-cholesterol levels, reflecting the presence of smaller LDL particle size. Whereas in men insulin levels, obesity, and nonHDL-cholesterol were major determinants, C-reactive protein (CRP) was the strongest determinant of AIP among women, independent of body mass index. Top quartiles of AIP predicted significantly age-adjusted incident coronary heart disease (CHD) in both sexes, more strongly in women, in whom quartile 3 also was a predictor with a greater than 2-fold relative risk. Associations remained significant after adjustment for CRP and traditional risk factors. AIP significantly predicted diabetes and high blood pressure in both sexes after adjustment for age and CRP. With regard to incident high blood pressure, the risk ratio in men was attenuated when body mass index also was adjusted.

Conclusions

High AIP, a surrogate of small LDL particle size, reflects obesity and hyperinsulinemia in men and high CRP status in women. It predicts CHD independently, type 2 diabetes mediated by obesity in men and in women, high blood pressure, metabolic syndrome, and CHD potentially mediated by involvement in a proinflammatory status reflected by CRP.

Aim: Determining the difference regarding obesity in German and Turkish adults.

Materials and Methods: This study examined a cross-section of adults aged 30-79 years old. Age-adjustment was uniformly provided for comparisons.

Results: Among 3055 Germans and 2925 Turks, Turkish women had significantly higher markers of (abdominal) obesity than German women, while waist circumference (WC) was similar among males. Blood pressure (BP), concentrations of total, LDL-cholesterol, and apolipoprotein B were significantly higher among Germans, whereas Turks had markedly higher fasting triglycerides and lower HDL-cholesterol. Unlike Germans, the current trend of smoking among Turks correlates with lower WC and lower systolic BP compared to non-smokers. Hip circumference was associated positively with atherogenic dyslipidemia more strongly among Germans than Turks. Changes in circumferences of waist and hip were significantly associated with elevated LDL-cholesterol, independent of BMI, in Germans, but not among Turks. Excess of overall obesity in Germans and Turkish females, and abdominal obesity among Turkish men, in addition to different sex, appeared to be major determinants of SBP. In contrast to Germans and Turkish males, atherogenic dyslipidemia was significantly associated with higher SBP in Turkish females.

Conclusions: Distribution of adiposity, and its interrelationship in German and Turkish adults, reveals substantial disparity that reflects pathogenetic differences; this requires modified emphasis of preventive and therapeutic measures.
