Programs that had professionals frequently interact with participants , regardless if the interactions were done daily , weekly , or monthly , led to a change in body composition .
Additionally , programs that incorporated a motivation theory and provided content relevant to participants ' needs result ed in a change in body composition .
Conclusion Evidence supports that future worksite wellness programs that are design ed using a motivational theory and content that is created relevant to participants ' needs and that has frequent interactions with participants may result in a change in body composition

OBJECTIVES To improve nutrition and physical activity of county employees and promote weight loss . DESIGN R and om assignment to begin the program when first offered or after 3 months ( " wait control " group ) . SETTING Worksite . PARTICIPANTS Onondaga County employees ( n = 45 ) at risk for diabetes ( n = 35 ) or with diabetes ( n = 10 ) . Mean ( ±SD ) age = 51.2 ( ± 8.0 ) years and body mass index ( BMI ) = 37.3 ± ( 6.8 kg/m ) . INTERVENTION Twelve weekly healthy lifestyle sessions based on the Diabetes Prevention Program curriculum , followed by monthly sessions for up to 12 months . OUTCOMES Medical : Weight , BMI , waist circumference , blood pressure , fasting glucose , lipid , and hemoglobin A1c levels . Psychosocial/behavioral : Health-related quality of life Short Form-12 , Impact of Weight on Quality of Life Scale ) , physical activity ( International Physical Activity Question naire ) , eating behavior ( 3-Factor Eating Question naire , National Cancer Institute Fat Screener ) , job satisfaction . RESULTS The intervention group lost significant weight compared to the wait control group over the first 3 months ( mean [ 95 % CI ] , -2.23 kg [ -3.5 to 0.97 ] ) vs [ + 0.73 kg ( + 0.17 to + 1.28 ) ] , with a decrease in BMI ( P < .001 ) and waist circumference ( P = .004 ) , an increase in physical activity ( International Physical Activity Question naire , P = .011 ) and lower dietary fat intake ( P = .018 ) . Over 12 months , 22.5 % ( 9/40 ) lost more than 5 % body weight and 12.5 % ( 5/40 ) lost more than 7 % body weight . After the first 3 months , there was gradual partial weight regain but reduction in waist circumference was maintained . The intervention group demonstrated significant improvement in Impact of Weight on Quality of Life Scale ( P < .001 ) , 3-Factor Eating ( cognitive restraint P < .001 , uncontrolled eating P = .003 , and emotional eating P = .001 ) , International Physical Activity Question naire ( P = .011 ) , and Short Form-12 Physical Component Summary ( P = .048 ) . No improvements were observed in blood pressure , lipid , hemoglobin A1c , or glucose levels . Job satisfaction was inversely related to BMI at baseline ( P = .001 ) with a trend for improvement with the modest weight loss .
