The prevalence of abdominal obesity is increasing worldwide. Adults with abdominal obesity have been reported to have increased risk of cardiometabolic disorders. The aim of this study was to examine whether non-obese subjects (body mass index (BMI) < 25 kg/m) with abdominal obesity examined in the framework of the Swiss-Hungarian Cooperation Programme had increased metabolic risk compared to participants without abdominal obesity.
A cross-sectional study was carried out in 5228 non-obese individuals. Data were collected between July 2012 and February 2016. Descriptive statistics, Pearson's correlation analysis and multiple logistic regression models were applied, odds ratios (OR) with 95% confidence interval (CI) being the outcomes.
607 (11.6%) out of the 5228 non-obese individuals had abdominal obesity. The correlation analysis indicated that the correlation coefficients between BMI and waist circumference (WC) were 0.610 in males and 0.526 in females. In this subgroup, the prevalence of high systolic blood pressure, high fasting blood glucose, and high total cholesterol and triglyceride levels were significantly higher. The logistic regression model based on these data showed significantly higher risk for developing high systolic blood pressure (OR = 1.53; 95% CI = 1.20-1.94), low HDL cholesterol (OR = 2.06; 95% CI = 1.09-3.89), and high trygliceride level (OR = 1.65; 95% CI = 1.27-2.16).
There was a very high, significant, positive correlation between WC and BMI. Abdominal obesity was found to be strongly related to certain metabolic risk factors among non-obese subjects. Hence, measuring waist circumference could be recommended as a simple and efficient tool for screening abdominal obesity and related metabolic risk even in non-obese individuals.
全球范围内腹型肥胖的患病率正在上升。有研究报道，腹型肥胖的成年人患心血管代谢疾病的风险增加。本研究旨在探讨在瑞士-匈牙利合作项目框架下检查的非肥胖者（BMI＜25kg/m）是否存在腹型肥胖，与无腹型肥胖者相比，其代谢风险是否增加。
对 5228 名非肥胖者进行横断面研究。数据收集于 2012 年 7 月至 2016 年 2 月期间。采用描述性统计、皮尔逊相关分析和多因素逻辑回归模型，计算比值比（OR）及其 95%置信区间（CI）。
5228 名非肥胖者中，607 人（11.6%）存在腹型肥胖。相关性分析表明，男性 BMI 与腰围（WC）的相关系数为 0.610，女性为 0.526。在此亚组中，高血压、空腹血糖、总胆固醇和甘油三酯水平升高的患病率显著更高。基于这些数据的逻辑回归模型显示，高血压（OR=1.53；95%CI=1.20-1.94）、低高密度脂蛋白胆固醇（OR=2.06；95%CI=1.09-3.89）和高甘油三酯血症（OR=1.65；95%CI=1.27-2.16）的发生风险显著增加。
WC 与 BMI 之间存在高度显著的正相关。在非肥胖者中，腹型肥胖与某些代谢危险因素密切相关。因此，即使在非肥胖个体中，测量腰围也可以作为筛查腹型肥胖及相关代谢风险的一种简单、有效的工具。
