Abstract:Objective To investigate the relationship between working hours and incidence of central obesity in sedentary workers. Methods Questionnaire surveys and waist circumference measurement were conducted among 920 sedentary workers selected by a multi-stage random cluster sampling method in a city from April to July 2019. And multifactor logistic regression model was used to analyze the correlation of working hours with the risk of central obesity. Results A total of 876 valid subjects were obtained from 920 participants. The average working hours were (48.73±3.61) hours/week, and the detection rate of central obesity was 40.63%. There were statistically significant differences in the detection rate of central obesity among subjects with different genders, ages, smoking status, alcohol consumption status, physical activity level and working hours(χ2= 16.703, χ2=21.617, χ2=16.584, χ2=14.523, χ2=27.021, χ2=20.917; all P<0.001). After controlling for the potentially confounding effects, compared with ≤ 34 hours/week,multifactor regression analysis revealed that the OR values of 35-55 hours/week and ≥ 56 hours/week were 1.35(95%CI=1.05-1.66)and 1.43(95%CI=1.19-1.73), respectively, with statistically significant differences (Wald χ2=9.717, Wald χ2=12.351, both P<0.01). Conclusion The incidence rate of central obesity in the sedentary workers was higher,and the increment of working hours was an independent risk factor for central obesity.
