Triglyceride (TG) abnormalities are the most prevalent type of dyslipidaemia in the people of northeast China. Many researchers have investigated the prevalence, treatment and control of TG abnormalities, but little is known about the associations between the TG values and the factors that influence TG levels. This study aims to reveal quantile-specific associations of TG with its risk factors. A sample of 16,340 participants in Jilin Province were included in this study. A quantile regression (QR) model was performed to identify the factors that affected TG levels in different quantiles. The distribution of TG levels was different between males and females (χ = 155.77, P < 0.001). Body mass index (BMI) and waist circumference (WC) were positively associated with TG levels in all quantiles. Drinking was positively associated with TG levels in high quantiles (P to P) only in males, while age had a positive association with TG levels in all quantiles only in females. The risk of WC on TG levels was higher with increasing TG levels, and smokers were more at risk for increasing TG levels, as well.
甘油三酯（TG）异常是中国东北地区人群中最常见的血脂异常类型。许多研究人员研究了 TG 异常的患病率、治疗和控制情况，但对于 TG 值与影响 TG 水平的因素之间的关联知之甚少。本研究旨在揭示 TG 与其危险因素之间的分位数特异性关联。本研究纳入了吉林省的 16340 名参与者。采用分位数回归（QR）模型来确定影响不同分位数 TG 水平的因素。TG 水平的分布在男性和女性之间存在差异（χ = 155.77，P < 0.001）。体重指数（BMI）和腰围（WC）与所有分位数的 TG 水平呈正相关。仅在男性中，饮酒与 TG 高水平（P 至 P）呈正相关，而年龄与所有分位数的 TG 水平仅在女性中呈正相关。随着 TG 水平的升高，WC 对 TG 水平的风险增加，吸烟者的 TG 水平也有升高的风险。
