Obesity and overweight are related to unfavourable lipoprotein subclass profiles. Here we studied the relation between weight change and lipoprotein particle concentrations and sizes in a general population cohort in a longitudinal setting.
The cohort included 683 adults with a 6.5-year follow-up. Lipoprotein particle subclasses and mean particle sizes of VLDL, LDL, and HDL were measured by nuclear magnetic resonance spectroscopy.
During the follow-up period, a weight loss of at least 5% was associated with decreased particle concentrations of all apoB-containing subclasses and increased concentrations of large HDL particles. Coherently, weight gain (≥5%) was associated with increases in all apoB-containing subclasses and decreases in total and medium HDL particle concentrations. The relatively largest increase occurred for large HDL particle concentration (24.1%, 95% CI 15.8-32.5) in weight loss and for large VLDL particle concentration (33.0%, 19.6-46.4) in weight gain. Weight change correlated positively with changes in apoB-containing lipoprotein particle concentrations and also with the change in average VLDL particle size. Negative correlations were found between weight change and the change in average LDL (r = -0.10) and HDL (r = -0.32) particle size, but not between weight change and total HDL particle concentration.
Moderate weight loss is related to favourable and weight gain to unfavourable changes in lipoprotein subclass profiles. These population level findings underline the importance of weight control as a modifier of cardiovascular risk factors.
肥胖和超重与不利的脂蛋白亚类谱有关。本研究在纵向研究中，研究了一般人群中体重变化与脂蛋白颗粒浓度和大小的关系。
该队列包括 683 名成年人，随访时间为 6.5 年。采用核磁共振光谱法测定 VLDL、LDL 和 HDL 的脂蛋白颗粒亚类和平均颗粒大小。
在随访期间，体重减轻至少 5%与所有载 apoB 的亚类颗粒浓度降低和大 HDL 颗粒浓度增加有关。一致地，体重增加（≥5%）与所有载 apoB 的亚类颗粒浓度增加和总 HDL 和中 HDL 颗粒浓度降低有关。体重减轻时大 HDL 颗粒浓度增加最大（24.1%，95%CI 15.8-32.5），体重增加时大 VLDL 颗粒浓度增加最大（33.0%，19.6-46.4）。体重变化与载 apoB 的脂蛋白颗粒浓度变化呈正相关，与 VLDL 颗粒平均大小的变化也呈正相关。体重变化与 LDL（r=-0.10）和 HDL（r=-0.32）颗粒平均大小的变化呈负相关，但与总 HDL 颗粒浓度的变化无相关性。
适度的体重减轻与脂蛋白亚类谱的有利变化有关，而体重增加与不利变化有关。这些人群水平的发现强调了体重控制作为心血管危险因素调节剂的重要性。
