Dyslipidaemia in adolescence tracks into adulthood and is an important risk factor for cardiovascular disease. Little is known about the effects of environmental exposures and early-life exposure to infectious diseases common to tropical regions on lipids. In 1119 early adolescent participants in the Entebbe Mother and Baby Study, we used linear regression to examine whether prenatal, childhood or adolescent factors are associated with lipid levels. Reduced high-density lipoprotein (HDL) and elevated triglyceride levels were common (prevalence 31% and 14%, respectively), but elevated low-density lipoprotein (LDL) or total cholesterol (TC) were rare. Current malaria infection was associated with lower mean LDL (adjusted ß - 0.51; 95% CI - 0.81, - 0.21), HDL (adjusted ß - 0.40; 95% CI - 0.56, - 0.23), and TC levels (adjusted ß - 0.62; 95% CI - 0.97, - 0.27), but higher mean triglyceride levels (geometric mean ratio (GMR) 1.47; 95% CI 1.18-1.84). Early-life asymptomatic malaria was associated with modest reductions in HDL and TC. Body mass index (BMI) was positively associated with LDL, TC, and triglycerides. No associations with helminth infection were found. Our findings suggest that early-life factors have only marginal effects on the lipid profile. Current malaria infection and BMI are strongly associated with lipids and important to consider when trying to improve the lipid profile.
青春期血脂异常会持续到成年期,是心血管疾病的重要危险因素。关于环境暴露和热带地区常见传染病的早期暴露对脂质的影响知之甚少。在恩特贝母婴研究中,我们对 1119 名早期青少年参与者进行了线性回归分析,以研究产前、儿童期或青春期因素是否与血脂水平有关。低高密度脂蛋白(HDL)和高甘油三酯水平较为常见(患病率分别为 31%和 14%),但低低密度脂蛋白(LDL)或总胆固醇(TC)升高则较为罕见。目前的疟疾感染与 LDL(调整后β-0.51;95%可信区间-0.81,-0.21)、HDL(调整后β-0.40;95%可信区间-0.56,-0.23)和 TC 水平(调整后β-0.62;95%可信区间-0.97,-0.27)降低有关,但与甘油三酯水平升高有关(几何均数比(GMR)1.47;95%可信区间 1.18-1.84)。儿童时期无症状疟疾与 HDL 和 TC 适度降低有关。体重指数(BMI)与 LDL、TC 和甘油三酯呈正相关。未发现与寄生虫感染有关。我们的研究结果表明,早期生活因素对血脂谱只有轻微影响。目前的疟疾感染和 BMI 与血脂密切相关,在试图改善血脂谱时需要考虑这两个因素。
