The conicity index is indicated as a tool for assessing the nutritional status of renal individuals undergoing hemodialysis. Thus, this study aimed to estimate the prevalence of abdominal obesity using the conicity index in individuals with chronic kidney disease undergoing hemodialysis to verify its association with sociodemographic, clinical, and lifestyle factors.
This is a cross-sectional study with 941 individuals undergoing hemodialysis in a metropolitan area in southeastern Brazil. The conicity index was estimated and cutoffs of 1.275 and 1.285 for men and women, respectively, were used. For the analysis of the results, binary logistic regression was performed and the odds ratio (OR) was estimated with their respective confidence intervals (95% CI).
The conicity index was high in 56.54% of men (95% CI: 34.34-70.16) and 43.46% of women (95% CI: 38.45-55.20). We found that both adult men (OR = 3.71; 95% CI: 2.27-6.07) and adult women (OR = 4.06; 95% CI: 2.41-6.84) were more likely to have abdominal obesity, as well as self-declared mixed-raced (OR: 1.74; 95% CI: 1.01-3.00) and single men (OR: 1.64; 95% CI: 1.00-2.68).
The conicity index is an important anthropometric indicator to estimate abdominal obesity in individuals with chronic kidney disease on hemodialysis.
圆锥指数被用作评估接受血液透析的肾脏个体营养状况的工具。因此，本研究旨在使用圆锥指数估计慢性肾脏病接受血液透析患者的腹型肥胖患病率，并验证其与社会人口学、临床和生活方式因素的相关性。
这是一项横断面研究，共有 941 名在巴西东南部大都市地区接受血液透析的个体。估计了圆锥指数，并分别使用男性和女性的 1.275 和 1.285 截断值。为了分析结果，进行了二元逻辑回归，并估计了比值比（OR）及其相应的置信区间（95%CI）。
男性的圆锥指数高（95%CI：34.34-70.16）占 56.54%，女性占 43.46%（95%CI：38.45-55.20）。我们发现，成年男性（OR=3.71；95%CI：2.27-6.07）和成年女性（OR=4.06；95%CI：2.41-6.84）更有可能患有腹型肥胖，以及自我报告的混合种族（OR：1.74；95%CI：1.01-3.00）和单身男性（OR：1.64；95%CI：1.00-2.68）。
圆锥指数是一种重要的人体测量指标，可用于估计慢性肾脏病接受血液透析患者的腹型肥胖。
