摘要

人体测量肥胖测量(AAMs),如身体质量指数(BMI)、腰围(WC)和腰臀比(WHR)被用来评估肥胖状况。国家特定的aam截断值将提供更准确的肥胖患病率估计。本横断面研究旨在确定斯里兰卡成年女性的AAMs、BMI、WC、臀围(HC)和WHR的最佳临界值。该研究在斯里兰卡加勒进行,350名30-60岁的健康社区中年妇女被分为两组(A组,n = 175, B组,n = 175)。用DXA测定体脂率(TBFP) (kg)。测量体重(kg)、身高(m)、腰围(WC)和身高(cm)。计算BMI (kg/m2)和WHR。a组妇女在TBFP水平为33%和35%时,以TBFP为标准,采用ROC曲线分析中的曲线下面积(AUC)确定最佳截断值。B组比较世界卫生组织(WHO)推荐的亚洲妇女肥胖截断值和新开发的斯里兰卡妇女肥胖截断值,确定肥胖发生率。与TBFP 33%对应的AAMs的最佳临界值为BMI, 24.5 kg/m2;WC, 80厘米;HC, 95厘米;WHR为0.83。TBFP 35%对应BMI的最佳临界值为25.0 kg/m2;WC, 85厘米;HC, 100厘米;WHR为0.83。根据世界卫生组织和新定义的TBFP 33%和35%的临界值对应的肥胖患病率(人数,%)如下:BMI = 83 (47.4%), 98 (56.0%), 83 (47.4%);Wc = 106(60.6%)、106(60.6%)、72 (41.1%);WHR = 140(80.0%)、106(60.6%)、106(60.6%)。本研究中观察到的BMI和WC的截止值在WHO对亚洲人群描述的范围内,分别对应33%和35%的TBFP水平。然而,世卫组织(亚洲)的WHR临界值与斯里兰卡女性的新确定值相比较低,同时高估了患病率。在临床应用之前,需要更多的研究来证实这些价值。

Optimal Cutoff Values for Anthropometric Adiposity Measures of Sri Lankan Adult Women
Anthropometric adiposity measures (AAMs) such as body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) are used to evaluate obesity status. Country-specific cutoff values of AAMs would provide more accurate estimation of obesity prevalence. This cross-sectional study was designed to determine the optimal cutoff values for AAMs, BMI, WC, hip circumference (HC), and WHR, of Sri Lankan adult women. The study was conducted in Galle, Sri Lanka, with 350 healthy community-dwelling middle-aged women aged 30–60 years, divided into two groups (Group A, n = 175 and Group B, n = 175). Total body fat percentage (TBFP) (kg) was measured with DXA. Body weight (kg), height (m), and WC and HC (cm) were measured. BMI (kg/m2) and WHR were calculated. Optimal cutoff values were determined by area under curve (AUC) in Receiver-Operating Characteristic (ROC) curve analysis using TBFP as the criterion at the TBFP level of 33% and 35% using the women in Group A. Then, the prevalence of obesity was determined in Group B while comparing the prevalence based on the cutoff values recommended by the World Health Organization (WHO) for Asians and the newly developed cutoff values for Sri Lankan women. Optimal cutoff values of AAMs which correspond to TBFP 33% are BMI, 24.5 kg/m2; WC, 80 cm; HC, 95 cm; and WHR, 0.83. TBFP 35% corresponds to the optimal cutoff values of BMI, 25.0 kg/m2; WC, 85 cm; HC, 100 cm; and WHR, 0.83. Prevalence of obesity (number, %) according to the WHO and newly defined cutoff values that correspond to TBFP 33% and 35% were as follows: BMI = 83 (47.4%), 98 (56.0%), 83 (47.4%); WC = 106 (60.6%), 106 (60.6%), 72 (41.1%); and WHR = 140 (80.0%), 106 (60.6%), 106 (60.6%). The observed cutoff values of BMI and WC in this study were within the ranges of those described by the WHO for Asian populations which correspond to the 33% and 35% TBFP levels, respectively. However, the WHR cutoff value of WHO (Asians) is lower when compared to the newly determined value for Sri Lankan females while overestimating the prevalence. More studies are needed to confirm these values before clinical use.
