ABSTRACT
Objective To study the effects of lifestyle quantilization based-weight management on overweight or obesity police officers.Methods One hundred and seven overweight or obesity police officers received lifestyle quantilization based-weight management (i.e.Jinbi weight management) and were then assigned to the excellent performance group (group A,n =50),good performance group (group B,n =42)and loss to follow-up group (group C,n =15).Dietary habits,body weight,height,waist circumference (WC),blood pressure (BP),total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C) and fasting plasma glucose (FPG) were measured before and after the intervention.After 8 weeks' intervention,the changes of above parameters were recored.Student's t test was used for data analysis.Results Of group A and B,83 reported weight loss (group A t =13.31,group B t =5.04 ; both P ＜ 0.05).In group A,body weight,body mass index (BMI),WC,body fat and visceral fat index were significantly decreased,in contrast to body water (t values were 13.31,13.72,10.8,8.59,6.83 and-6.62,respectively; all P ＜ 0.05).However,there were no significant changes of BP,FPG,TC,TG,LDL-C and HDL-C in group A.Following intervention,daily dietary energy intake of group A was reduced by 74.1 k J,fat intake was decreased by 11.6 g,energy ratio of dietary fat was decreased by 1.8％,energy ratio of cereal was increased by 4.2％,and sodium chloride and cooking oil was decreased by 1.3 g and 10 g,respectively.Conclusion Lifestyle quantilization based-weight management shows effectiveness among overweight or obese police officers,and thus may be recommended for other functional communities.
