To study the relationship of ethnicity with overweight/obesity, variation in adiposity levels, regional distribution of fat and its impact on cardio-respiratory health among selected ethnic groups.
A cross-sectional study was carried out among 300 young adults of three ethnic groups from different geographical regions of India ranging in age from 20 to 30 years. Stature, weight, circumferences, body fat percentage, and skinfold thicknesses were measured. Obesity indices like body mass index (BMI), grand mean thickness (GMT), waist hip ratio (WHR), waist height ratio (WHtR), and conicity index (CI) were computed. Cardio-respiratory health indicators such as lung functions including forced expiratory volume in 1 s (FEV(1.0)), forced vital capacity (FVC), forced expiratory ratio (FER), peak expiratory flow rate (PEFR), breath holding time (BHT), and systolic and diastolic BP (blood pressure) were taken and associated with obesity indices.
General body fat deposition, assessed by BMI, GMT, and fat percentage, was found to be the highest among Delhi females and males. However, central adiposity as assessed from WHR, WHtR, and CI was found to be significantly higher among the Manipur subjects signifying a relatively more androidal pattern of fat deposition. Most of the inter-group differences for adiposity indices were significant; however, it was not so in the case of blood pressure among different ethnic groups. On the other hand, the respiratory efficiency varied significantly between different ethnic groups. Ethnicity, adiposity, and cardio-respiratory health were found to be interrelated.
Subjects belonging to three ethnic groups showed marked differences in different body dimension, adiposity indices, and cardio-respiratory health. Central obesity has been found to be a better pointer for cardiovascular health risk. There were ethnic and gender differences with respect to adiposity measures and cardio-respiratory health indicators.
研究特定族群中种族与超重/肥胖、肥胖程度差异、脂肪的区域分布及其对心肺健康的影响之间的关系。
对来自印度不同地理区域的300名年龄在20至30岁之间的三个族群的年轻成年人进行了一项横断面研究。测量了身高、体重、周长、体脂百分比和皮褶厚度。计算了肥胖指数，如体重指数（BMI）、总平均厚度（GMT）、腰臀比（WHR）、腰高比（WHtR）和锥度指数（CI）。采集了心肺健康指标，如肺功能，包括1秒用力呼气量（FEV(1.0)）、用力肺活量（FVC）、用力呼气比率（FER）、呼气峰值流速（PEFR）、屏气时间（BHT）以及收缩压和舒张压，并将其与肥胖指数相关联。
通过BMI、GMT和脂肪百分比评估的总体脂肪沉积在德里女性和男性中最高。然而，从WHR、WHtR和CI评估的中心性肥胖在曼尼普尔受试者中显著更高，这表明脂肪沉积模式相对更倾向于男性型。肥胖指数的大多数组间差异具有显著性；然而，不同族群的血压情况并非如此。另一方面，不同族群之间的呼吸效率差异显著。种族、肥胖和心肺健康被发现是相互关联的。
属于三个族群的受试者在不同身体维度、肥胖指数和心肺健康方面存在显著差异。中心性肥胖已被发现是心血管健康风险的更好指标。在肥胖测量和心肺健康指标方面存在种族和性别差异。
