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
Background Adult obesity is globally recognized as a public health concern .
As adults spend most of their weekdays at work , worksite wellness programs may include topics of nutrition education and physical activity to improve an employee 's body composition .
However , results are inconsistent with the impact they have on employees ' body composition .
Objective The purpose of this systematic review was to evaluate  worksite wellness nutrition and physical activity programs and their subsequent impact on participants ' body composition .
Comparison of strategies for sustaining weight loss: the weight loss maintenance randomized controlled trial.
CONTEXT Behavioral weight loss interventions achieve short-term success , but re-gain is common . OBJECTIVE To compare 2 weight loss maintenance interventions with a self-directed control group . DESIGN , SETTING , AND PARTICIPANTS Two-phase trial in which 1032 overweight or obese adults ( 38 % African American , 63 % women ) with hypertension , dyslipidemia , or both who had lost at least 4 kg during a 6-month weight loss program ( phase 1 ) were r and omized to a weight-loss maintenance intervention ( phase 2 ) . Enrollment at 4 academic centers occurred August 2003-July 2004 and r and omization , February-December 2004 . Data collection was completed in June 2007 . INTERVENTIONS After the phase 1 weight-loss program , participants were r and omized to one of the following groups for 30 months : monthly personal contact , unlimited access to an interactive technology-based intervention , or self-directed control . Main Outcome Changes in weight from r and omization . RESULTS Mean entry weight was 96.7 kg . During the initial 6-month program , mean weight loss was 8.5 kg . After r and omization , weight regain occurred . Participants in the personal-contact group regained less weight ( 4.0 kg ) than those in the self-directed group ( 5.5 kg ; mean difference at 30 months , -1.5 kg ; 95 % confidence interval [ CI ] , -2.4 to -0.6 kg ; P = .001 ) . At 30 months , weight regain did not differ between the interactive technology-based ( 5.2 kg ) and self-directed groups ( 5.5 kg ; mean difference -0.3 kg ; 95 % CI , -1.2 to 0.6 kg ; P = .51 ) ; however , weight regain was lower in the interactive technology-based than in the self-directed group at 18 months ( mean difference , -1.1 kg ; 95 % CI , -1.9 to -0.4 kg ; P = .003 ) and at 24 months ( mean difference , -0.9 kg ; 95 % CI , -1.7 to -0.02 kg ; P = .04 ) . At 30 months , the difference between the personal-contact and interactive technology-based group was -1.2 kg ( 95 % CI -2.1 to -0.3 ; P = .008 ) . Effects did not differ significantly by sex , race , age , and body mass index subgroups . Overall , 71 % of study participants remained below entry weight . CONCLUSIONS The majority of individuals who successfully completed an initial behavioral weight loss program maintained a weight below their initial level . Monthly brief personal contact provided modest benefit in sustaining weight loss , whereas an interactive technology-based intervention provided early but transient benefit .
