Abstract
The first aim of this study was to compare body mass index (BMI) (indirect method) classification with the body fat percent (PBF) (direct method) and to determine how BMI classifies subjects with different levels of skeletal muscle mass percent (PSMM). The second aim was to determine the prevalence of overweight and obesity status among police trainees (PTs). A total of 103 male PTs participated in this research: age = 21.46 ± 0.64 years, body mass (BM) = 75.97 ± 8.10 kg, body height (BH) = 174.07 ± 6.31 cm, BMI = 25.05 ± 2.12 kg/m2. The InBody 370 multichannel bioelectrical impedance analysis (BIA) measured body composition. Study results indicated that muscular PTs could be misclassified as overweight and that PBF identified more subjects as obese. Namely, three PTs were obese according to BMI, while 13 were obese according to PBF. The information provided by this research could be used to help professionals understand the importance of measuring body composition, and the inaccuracies in BMI classification. In conclusion, whenever possible PSMM and PBF should replace the utilization of BMI to screen overweight and obesity in PTs. Agencies may think of using BIA as non-invasive, quick and inexpensive measurement tool.
Highlights
Body composition assessment is often used for members of the police force as an important tool for evaluation of physical fitness and health status [1,2,3]
The descriptive statistics for the sample age and body composition characteristics are shown in Table 1 as mean, standard deviations (SD), minimum and maximum values
The findings of this study suggest that, while Body mass index (BMI) can be used as quick assessment of police trainees (PTs)’s obesity status, it is not considered to be an entirely accurate method for obesity screening in PTs when compared with measurement of percent of body fat (PBF) and percent of skeletal muscle mass (PSMM)
Summary
Body composition assessment is often used for members of the police force as an important tool for evaluation of physical fitness and health status [1,2,3]. Body composition is a valuable assessment since it is the result of various factors such as diet, stress, the amount of physical activity, and other daily habits [4,5,6,7]. Body mass index (BMI) levels have been frequently correlated with physical fitness and used to evaluate body composition status in the police workforce [1,10,11,12,13].
