Abstract：
BACKGROUND: Ethnic and gender differences in plasma lipid composition have been widely reported among the general population, but there are scarce data on athletes.
OBJECTIVE: To assess ethnic and gender differences in lipid profile across a large cohort of Olympic athletes practicing different sport disciplines METHODS: We enrolled 1165 Olympic athletes divided into power, endurance, and mixed disciplines according to European Society of Cardiology classification. Sixty-two (5.3%) were Afro-Caribbean. Body composition and fat mass percentage were measured. Blood samples were collected and lipid profile was investigated.
RESULTS: Compared to Caucasians, Afro-Caribbeans had better lipid profile characterized by lower LDL (90 ± 25 mg/dL vs. 97.1 ± 26.2 mg/dL, p = 0.032) lower LDL/HDL ratio (1.39 ± 0.5 vs. 1.58 ± 0.6, p = 0.012), lower non-HDL-cholesterol (102.5 ± 27.4 mg/dL vs. 111.5 ± 28.5 mg/dL, p = 0.015) and lower TC/HDL (2.59 ± 0.6 vs. 2.82 ± 0.7, p = 0.010). Female Afro-Caribbeans showed lower TG/HDL ratio (p = 0.045) and TC/HDL ratio (p = 0.028), due to higher HDL (p = 0.005) compared to male Afro-Caribbeans. In Caucasian athletes, females showed even more evident differences with lower TC, LDL, and higher HDL with subsequent lower ratios compared to men. Moreover, endurance Caucasian athletes had lower LDL (p = 0.003) and TG (p = 0.017) plasmatic levels and higher HDL levels compared to non-endurance Caucasian athletes (p< 0.0001) CONCLUSIONS: Ethnicity and gender have a significant influence on plasmatic lipid balance in elite athletes and Afro-Caribbeans have favorable lipid profiles compared to Caucasians. Moreover, endurance sports, particularly in Caucasian athletes, are associated with better lipid profile compared to other type of sports.

摘要：
背景：在一般人群中广泛报道了血浆脂质组成的种族和性别差异，但是关于运动员的数据很少。
目的：为了评估不同运动学科的大批奥林匹克运动员在血脂方面的种族和性别差异。方法：我们招募了1165名奥林匹克运动员，耐力,和根据欧洲心脏病学会分类的混合学科。62人（5.3％）是非洲加勒比。测量身体成分和脂肪质量百分比。收集血液样品并研究脂质分布。
结果：与白种人相比，非洲加勒比海地区的血脂状况更好，LDL较低（90±25mg/dLvs.97.1±26.2mg/dL，p=0.032）降低LDL/HDL比率（1.39±0.5vs.1.58±0.6，p=0.012），较低的非HDL-胆固醇（102.5±27.4mg/dLvs.111.5±28.5mg/dL，p=0.015）和更低的TC/HDL（2.59±0.6vs.2.82±0.7，p=0.010）。女性非洲加勒比显示较低的TG/HDL比率（p=0.045）和TC/HDL比率（p=0.028），与男性非洲加勒比人相比，高密度脂蛋白较高(p=0.005)。在高加索运动员中，女性表现出更明显的差异与较低的TC，LDL,与男性相比，HDL较高，随后比率较低。此外，与非耐力高加索运动员相比,耐力高加索运动员的LDL(p=0.003)和TG(p=0.017)血浆水平较低,HDL水平较高(p<0.0001)。此外，耐力运动,尤其是高加索运动员，与其他类型的运动相比，它们具有更好的血脂特征。
