Previous studies found that remnant cholesterol (RC) is a risk factor for cardiovascular diseases and childhood obesity is associated with cardiometabolic diseases. This study aimed to explore the relationship between RC and abdominal obesity in children.
A total of 5,959 children, aged 6-12 years old, were selected from a cross-sectional study in urban-rural areas of Chongqing, China. RC was calculated by total cholesterol (TC)-high-density lipoprotein (HDL-C) cholesterol-low-density lipoprotein (LDL-C) cholesterol and was divided into four groups by quartiles (Q1-Q4).
Compared to children with the lowest RC (Q1), children with higher RC had significantly higher odds of abdominal obesity (Q2: OR = 1.450, 95% CI: 1.131-1.859, < 0.05; Q3: OR = 2.127, 95% CI: 1.632-2.772, < 0.001; Q4: OR = 2.386, 95% CI: 1.819-3.130, < 0.001). In the stratified analyses by urban-rural areas, the odds ratios were greater in rural areas (Q2: OR = 2.228, 95% CI: 1.572-3.160, < 0.001; Q3: OR = 3.668, 95% CI: 2.191-6.140, < 0.001; Q4: OR = 6.490, 95% CI: 2.271-18.551, < 0.001) than in urban areas (Q2: OR = 1.644, 95% CI: 1.192-2.266, < 0.05; Q3: OR = 2.266, 95% CI: 1.667-3.082, < 0.001; Q4: OR = 2.711, 95% CI: 2.005-3.665, < 0.001).
Our study found that RC was positively correlated with abdominal obesity in children, and this association was higher for children living in rural areas.
既往研究发现，残余胆固醇（RC）是心血管疾病的危险因素，儿童肥胖与心脏代谢疾病相关。本研究旨在探讨儿童RC与腹型肥胖之间的关系。
从中国重庆城乡地区的一项横断面研究中选取了5959名6至12岁的儿童。RC通过总胆固醇（TC）-高密度脂蛋白（HDL-C）胆固醇-低密度脂蛋白（LDL-C）胆固醇计算得出，并按四分位数（Q1-Q4）分为四组。
与RC最低的儿童（Q1）相比，RC较高的儿童腹型肥胖的几率显著更高（Q2：OR = 1.450，95%CI：1.131-1.859，P<0.05；Q3：OR = 2.127，95%CI：1.632-2.772，P<0.001；Q4：OR = 2.386，95%CI：1.819-3.130，P<0.001）。在按城乡地区分层分析中，农村地区的比值比高于城市地区（Q2：OR = 2.228，95%CI：1.572-3.160，P<0.001；Q3：OR = 3.668，95%CI：2.191-6.140，P<0.001；Q4：OR = 6.490，95%CI：2.271-18.551，P<0.001）（城市地区：Q2：OR = 1.644，95%CI：1.192-2.266，P<0.05；Q3：OR = 2.266，95%CI：1.667-3.082，P<0.001；Q4：OR = 2.711，95%CI：2.005-3.665，P<0.001）。
我们的研究发现，儿童RC与腹型肥胖呈正相关，且这种关联在农村地区儿童中更高。
