AIMS
The role of adult HDL-C in atherosclerotic cardiovascular disease (ASCVD) faces challenges from Mendelian randomisations and drug trials. However, the association between childhood HDL-C and its changes and adult ASCVD remains undefined. This study aimed to determine this association.
METHODS
Participants: Children in the International Childhood Cardiovascular Cohort (i3C) Consortium with childhood HDL-C and adult ASCVD follow-up. Age- and sex-standardized HDL-C z-scores were calculated for childhood (3-19 years), early childhood (3-11 years), and adolescence (12-19 years); Low HDL-C defined as <1.03mmol/L; Participants classified as consistently normal, low-to-normal, normal-to-low, and consistently low based on HDL-C status at early childhood and adolescence. ASCVD events: Identified using self-reports adjudicated by medical records or death registries. Analysis: Cox proportional hazards models quantified the associations between childhood HDL-C and adult ASCVD.
RESULTS
The study included 38,589 participants (49.7% males, mean age in 2016: 46.4 years) with 779 ASCVD and 784 imputed ASCVD events. After adjusting for sex, cohort, age and HDL-C measurement year, higher HDL-C z-scores in childhood, early childhood and adolescence were associated with lower adult ASCVD risk (HRs: 0.81-0.82), with the lowest risk at HDL-C >1.50mmol/L. Normal-to-low (HR 1.38, 95%CI 1.04-1.82) and consistently low (HR 1.94, 95%CI 1.45-2.63) childhood HDL-C increased adult ASCVD risk compared to consistently normal HDL-C. Adjusting for BMI and triglycerides weakened these associations.
CONCLUSIONS
Childhood and adolescent HDL-C were prospectively and inversely associated with adult ASCVD, suggesting that low HDL-C could be a risk maker of adult ASCVD. Future replications, mechanistic studies and Mendelian randomisations on childhood HDL-C may clarify its causal effects on adult ASCVD.
目的
成人高密度脂蛋白胆固醇（HDL-C）在动脉粥样硬化性心血管疾病（ASCVD）中的作用面临孟德尔随机化研究和药物试验的挑战。然而，儿童期HDL-C及其变化与成人ASCVD之间的关联仍不明确。本研究旨在确定这种关联。
方法
参与者：国际儿童心血管队列（i3C）联盟中具有儿童期HDL-C和成人ASCVD随访数据的儿童。计算儿童期（3 - 19岁）、幼儿期（3 - 11岁）和青春期（12 - 19岁）年龄和性别标准化的HDL-C z评分；低HDL-C定义为<1.03mmol/L；根据幼儿期和青春期的HDL-C状态，参与者分为持续正常、低到正常、正常到低和持续低四类。ASCVD事件：通过病历或死亡登记处判定的自我报告来确定。分析：Cox比例风险模型量化儿童期HDL-C与成人ASCVD之间的关联。
结果
该研究纳入了38589名参与者（49.7%为男性，2016年平均年龄：46.4岁），有779例ASCVD事件和784例推定的ASCVD事件。在调整性别、队列、年龄和HDL-C测量年份后，儿童期、幼儿期和青春期较高的HDL-C z评分与较低的成人ASCVD风险相关（风险比：0.81 - 0.82），HDL-C>1.50mmol/L时风险最低。与持续正常的HDL-C相比，儿童期正常到低（风险比1.38，95%置信区间1.04 - 1.82）和持续低（风险比1.94，95%置信区间1.45 - 2.63）的HDL-C增加了成人ASCVD风险。调整体重指数和甘油三酯后，这些关联减弱。
结论
儿童期和青春期的HDL-C与成人ASCVD呈前瞻性负相关，表明低HDL-C可能是成人ASCVD的一个风险指标。未来对儿童期HDL-C进行重复研究、机制研究和孟德尔随机化研究可能会阐明其对成人ASCVD的因果效应。
