To identify high-density lipoprotein (HDL) subfractions associated with longevity in men.
Fifty-three-year prospective follow-up of Gofman's Livermore Cohort between 1954 and 2008.
Lawrence Livermore National Laboratory.
One thousand one hundred forty-four men who consented to the study, had analytic ultracentrifuge measurements of lipoprotein subfractions at baseline, and were old enough at baseline to have survived to age 85 during follow-up.
Survival was determined according to participant contact, Social Security Death Index, and National Death Index.
Three hundred ninety men survived to 85 years old (34.1%). Survivors were less likely than nonsurvivors to be in the lowest HDL3 (% (standard error) 18.5% (2.0%) vs 27.3% (1.6%), P < .001) and HDL2 (22.1% (2.1%) vs 27.7% (1.6%), P = .04) quartiles. Logistic regression analyses showed that the lowest HDL3 quartile significantly predicted shorter longevity (P = .002), whereas the linear increases per mg/dL of HDL3 did not (P = .38), suggesting a risk threshold proximal to the 25th percentile. Men who were above the 25th HDL3 percentile had 70% greater odds of surviving until age 85 than those below this level, which persisted when adjusted for HDL2, very low-density lipoprotein (LDL), and standard risk factors. Proportional hazard analyses of survival before age 85 showed that being in the lowest HDL3 quartile increased age-adjusted cancer risk by 39% (P = .05) and noncancer risk by 23% (P = .04) when adjusted for other risk factors. Survivors also smoked less (mean ± SD 0.31 ± 0.48 vs 0.57 ± 0.56 packs/d, P < .001), had lower systolic (118.36 ± 11.08 vs 122.81 ± 13.55 mmHg, P < .001) and diastolic (70.61 ± 8.59 vs 73.14 ± 9.22 mmHg, P < .001) blood pressures and lower LDL mass (359.55 ± 80.42 vs 374.37 ± 86.10 mg/dL, P = .009) and total cholesterol concentrations (229.51 ± 43.21 vs 235.89 ± 45.40 mg/dL, P = .04) than nonsurvivors.
Low HDL3 reduces the odds of extended survival in men, independent of HDL2, other lipoproteins, and standard risk factors.
确定与男性长寿相关的高密度脂蛋白(HDL)亚群。
1954 年至 2008 年期间,对 Gofman 的 Livermore 队列进行了 53 年的前瞻性随访。
劳伦斯利弗莫尔国家实验室。
1144 名同意参加研究的男性,在基线时有脂蛋白亚组分的分析超速离心测量值,并且在基线时年龄足够大,可以在随访中活到 85 岁。
根据参与者的联系、社会保障死亡指数和国家死亡指数确定生存情况。
390 名男性活到 85 岁(34.1%)。与非幸存者相比,幸存者更不可能处于最低 HDL3(%(标准误差)18.5%(2.0%)与 27.3%(1.6%),P<.001)和 HDL2(22.1%(2.1%)与 27.7%(1.6%),P=.04)四分位数。逻辑回归分析表明,最低 HDL3 四分位数显著预测寿命较短(P=.002),而每毫克/分升 HDL3 的线性增加并没有(P=.38),表明接近 25%分位数的风险阈值。高于 HDL3 第 25 百分位的男性比低于此水平的男性存活至 85 岁的可能性高 70%,当调整 HDL2、极低密度脂蛋白(LDL)和标准风险因素时,这种情况仍然存在。在 85 岁之前的生存比例风险分析表明,处于最低 HDL3 四分位数时,癌症风险增加 39%(P=.05),非癌症风险增加 23%(P=.04),当调整其他风险因素时。幸存者吸烟也较少(平均±标准差 0.31±0.48 与 0.57±0.56 包/天,P<.001),收缩压(118.36±11.08 与 122.81±13.55 mmHg,P<.001)和舒张压(70.61±8.59 与 73.14±9.22 mmHg,P<.001)较低,LDL 质量(359.55±80.42 与 374.37±86.10 mg/dL,P=.009)和总胆固醇浓度(229.51±43.21 与 235.89±45.40 mg/dL,P=.04)也较低。
在男性中,低 HDL3 降低了长寿的几率,独立于 HDL2、其他脂蛋白和标准风险因素。
