Reports on the cardiorespiratory fitness and body composition of male workers engaged in processing of tea leaves in factories within the tea-estates of West Bengal, under the influence of physiological workload, are quite scanty.
This cross-sectional study was conducted to evaluate morphometric characteristics based on physiological status and physical fitness of tea factory laborers who are continuously exposed to tea dust in their work environment for more than two years.
Subjects were divided into control and tea garden workers groups. Height and weight were measured and the body mass index (BMI) was computed. Physiological parameters such as resting heart rate, blood pressure, fitness variables like physical fitness index (PFI), energy expenditure (EE), handgrip strength and anthropometric parameters like mid-upper arm (MUAC), thigh circumference (TC), head circumference (HC) and waist-to-hip ratio (WHR) were measured.
Body surface area (BSA), BMI, body fat percentage and fitness variables (PFI, EE) showed significant difference (p < 0.05) between the two groups. Anthropometric measures (MUAC, TC, HC, WHR) reflected poor status among laborers.
The present study shows that the majority of workers had ectomorph stature, good physical fitness, but had poor nutritional status (BMI and WHR).
关于西孟加拉邦茶叶种植园内工厂从事茶叶加工的男性工人在生理负荷影响下的心肺功能和身体成分的报告相当稀少。
本横断面研究旨在评估在工作环境中持续接触茶尘两年以上的茶厂工人基于生理状况和身体素质的形态特征。
将受试者分为对照组和茶园工人组。测量身高和体重并计算体重指数（BMI）。测量生理参数如静息心率、血压，身体素质变量如身体素质指数（PFI）、能量消耗（EE）、握力，以及人体测量参数如中上臂围（MUAC）、大腿围（TC）、头围（HC）和腰臀比（WHR）。
两组之间的体表面积（BSA）、BMI、体脂百分比和身体素质变量（PFI、EE）存在显著差异（p < 0.05）。人体测量指标（MUAC、TC、HC、WHR）反映出工人的状况较差。
本研究表明，大多数工人具有外胚层体型，身体素质良好，但营养状况较差（BMI和WHR）。
