Effect of lifestyle quantilization based-weight management on overweight or obesity occupational groups

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 kJ, 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.
