The present study examines the relationship between different adiposity markers and physical fitness based on occupation. A cross sectional sample of 82 security guards (mean age: 36.86 ± 8.72) and 43 students (mean age: 23.4 ± 3.86) of Delhi University were studied. Anthropometric measurements (height, body weight, waist and hip circumference) and socio-demographic characteristics were ascertained. Body composition parameters (body fat percentage, fat mass, fat free mass, muscle mass, total body water, bone mass and visceral fat) were assessed by bioelectric-impedance method using Tanita Body Composition Analyzer (BCA). Harvard step test was performed to test the physical fitness using Rapid Fitness Index. Student’s t test was used to compare the physical fitness and adiposity markers between the security guards and the students. ANOVA was used to categorize the level of physical fitness with adiposity markers amongst the two groups. As RFI scores decreased, mean value of body weight, waist circumference, hip circumference, MUAC, fat mass, visceral fat and BMI increased among the security guards showing a trend which indicates that with an increase in adiposity, the tendency to perform physical work decreases. However, no consistent trend as such was observed amongst the students between the RFI categories. Nevertheless, Delhi University students were found to be more physically fit than the security guards that may be attributable to the differences in their leisure time physical activity preferences and occupational workloads besides the underlying genetic, metabolic or dietary influences. Workplace interventions to reduce occupational sitting among the university security guards may boost cardiorespiratory fitness in the long run.展开更多
