Central adiposity has been linked with adverse metabolic profile including dyslipidaemia but recent studies suggested that peripheral fat distribution play a role in regulating daily fluxes in circulating non-esterified fatty acids. We examine whether lipid levels vary between central and peripheral fat distribution in the general population.
We examined the cross-sectional relation between fat distribution indices and lipid concentration in 20,021 apparently healthy men and women of the Norfolk cohort of the European Investigation into Cancer and Nutrition (EPIC-Norfolk). Waist-hip ratio was positively related to total and low density lipoprotein (LDL) cholesterol and negatively related to high density lipoprotein (HDL) cholesterol in both men and women, independently of body mass index (BMI). Although similar results were noted for waist circumference, individuals with bigger hip circumference had lower total and LDL-cholesterol and higher HDL-cholesterol when adjusting for BMI and/or waist circumference in both men and women.
Regional fat distribution was related to lipid profile independently of BMI. The independent contribution of waist and hip circumference in opposite directions was intriguing. These findings may help explain the associations observed between different fat distribution phenotypes and coronary heart disease.
中心性肥胖与包括血脂异常在内的不良代谢状况有关,但最近的研究表明,外周脂肪分布在调节循环中非酯化脂肪酸的每日通量中起作用。我们研究了一般人群中中心性和外周性脂肪分布之间血脂水平是否存在差异。
我们在欧洲癌症与营养调查诺福克队列(EPIC-Norfolk)的20021名表面健康的男性和女性中,研究了脂肪分布指数与血脂浓度之间的横断面关系。无论男性还是女性,腰臀比与总胆固醇和低密度脂蛋白(LDL)胆固醇呈正相关,与高密度脂蛋白(HDL)胆固醇呈负相关,且独立于体重指数(BMI)。虽然腰围也有类似结果,但在调整BMI和/或腰围后,无论男性还是女性,臀围较大的个体总胆固醇和低密度脂蛋白胆固醇较低,高密度脂蛋白胆固醇较高。
区域脂肪分布与血脂谱有关,且独立于BMI。腰围和臀围在相反方向上的独立作用很有趣。这些发现可能有助于解释不同脂肪分布表型与冠心病之间的关联。
