Atherosclerotic changes associated with dyslipidemia and increased cardiovascular disease risk are believed to begin in childhood. While previous studies have linked added sugars consumption to low high-density lipoprotein (HDL), little is known about the long-term impact of this consumption. This study aims to assess the association between added sugars intake and HDL cholesterol levels during adolescence, and whether this association is modified by obesity.
We used data from the National Heart Lung and Blood Institute's Growth and Health Study, a 10-year cohort study of non-Hispanic Caucasian and African-American girls (N=2379) aged 9 and 10 years at baseline recruited from 3 sites in 1987-1988 with biennial plasma lipid measurement and annual assessment of diet using a 3-day food record. Added sugars consumption was dichotomized into low (0% to <10% of total energy) and high (≥10% of total energy). In a mixed model controlling for obesity, race, physical activity, smoking, maturation stage, age, and nutritional factors, low compared with high added sugar consumption was associated with a 0.26 mg/dL greater annual increase in HDL levels (95% CI 0.48 to 0.04; P=0.02). Over the 10-year study period, the model predicted a mean increase of 2.2 mg/dL (95% CI 0.09 to 4.32; P=0.04) among low consumers, and a 0.4 mg/dL decrease (95% CI -1.32 to 0.52; P=0.4) among high consumers. Weight category did not modify this association (P=0.45).
Low added sugars consumption is associated with increasing HDL cholesterol levels throughout adolescence.
与血脂异常和心血管疾病风险增加相关的动脉粥样硬化变化据信始于儿童期。虽然先前的研究已经将添加糖的消耗与低高密度脂蛋白(HDL)联系起来,但对于这种消耗的长期影响知之甚少。本研究旨在评估青少年时期添加糖摄入量与 HDL 胆固醇水平之间的关系,以及这种关系是否受肥胖的影响。
我们使用了美国国立心肺血液研究所生长与健康研究的数据,这是一项为期 10 年的非西班牙裔白人和非裔美国女孩队列研究(N=2379),年龄在基线时为 9 岁和 10 岁,于 1987 年至 1988 年从 3 个地点招募,每两年测量一次血浆脂质,并使用 3 天的食物记录每年评估一次饮食。添加糖的摄入量分为低(总能量的 0%至<10%)和高(总能量的≥10%)两类。在控制肥胖、种族、体力活动、吸烟、成熟阶段、年龄和营养因素的混合模型中,与高添加糖摄入量相比,低添加糖摄入量与 HDL 水平每年增加 0.26mg/dL 相关(95%CI 0.48 至 0.04;P=0.02)。在 10 年的研究期间,该模型预测低消费组的 HDL 水平平均增加 2.2mg/dL(95%CI 0.09 至 4.32;P=0.04),高消费组的 HDL 水平则降低 0.4mg/dL(95%CI -1.32 至 0.52;P=0.4)。体重类别并未改变这种关联(P=0.45)。
青少年时期低添加糖的摄入与 HDL 胆固醇水平的升高有关。
