A Study on the Percentage of Body Fat and Abdominal Obesity of Workers Using Bioelectrical Impedance Analysis
Young-Sun Park, Jong-Dae Kim
Daegu Oriental Hospital of Daeguhaany University
Objectives: Obesity is chronic condition which can severely influence health. People with a high percentage of body fat (%BF) have high prevalence of hypertension and hypercholesterolemia. Abdominal obesity (AO) seems to play a major role in the development of cardiovascular disease, diabetes and hyperlipidemia. This study investigated the
%BF and AO of workers in the automobile manufacturing industry.
Methods: The subjects were categorized by sex, age, job class, drinking history and smoking history. %BF and AO were measured by using bioelectrical impedance analysis (Jawon Medical, Seoul, Korea). We analyzed the relationship between age, sex, job class, drinking history, smoking history and %BF and WHR into frequencies, χ
2-test using the SPSS Ver. 12.0.
Results: Regarding the relationship between sex and %BF, AO, there was statistically significant difference as men had a significant higher level of %BF and AO than women. There was a positive correlation between age and both
%BF and AO. Workers in their 40s especially ran level of AO up. In job class, office workers were apt to have a higherlevel of %BF and AO than production line workers. %BF and AO of the non-drinker group showed a lower level than the drinker group. On the other hand, the ex-smoker group had higher levels of %BF and AO than the non-smoker or current-smoker groups.
Conclusions: The above results showed that men, the advanced in years, office workers, drinkers and ex-smokers had high levels of %BF and AO.
