The Healthy Weight for Life Program (HWL)

November 10, 2011 updated by: Susan Roberts, Tufts University

This study is a randomized controlled pilot of a work site weight control intervention. The purpose of the pilot is to obtain preliminary data for future NIH submissions. Four work sites were identified through a multistage recruiting process. Work sites were randomized to either the intervention group, which will receive the intervention immediately following randomization or the control group which will receive a shortened intervention over a 1-month period, 6 months after the active intervention sites have completed their program. The intervention will consist of a variety of activities conducted over a 6 month period, that are overseen by a work site-Tufts oversight group, including the following optional elements: For overweight and obese individuals, regular support groups for weight loss and prevention of weight regain. For all work site employees irrespective of weight, handouts and posted informational resources on healthy eating, monthly lunchtime seminars, and food sampling to facilitate healthy eating patterns for prevention of weight gain.

Basic online assessments on health and nutrition will be carried out at baseline (week 0) and 24 weeks in all work site employees willing to provide information. More detailed online and in-person assessments will be performed throughout the 24-week study period in the weight loss support group participants (intervention sites) and individuals intending to enroll in the support group (control sites).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention Group

Monthly, all-worksite activities will be implemented to raise awareness of healthy nutrition for weight control throughout the worksite. The purpose of the all-worksite activities is: a) to create a supportive worksite-wide atmosphere for the individuals enrolling in the weight loss support group, and b) to provide low-level weight loss support for individuals who wish to prevent weight gain.

Individuals with eligible weight (defined as BMI ≥ 25 kg/m2) without medical contradictions to weight loss, who wish to join a support group to lose weight, may enroll in the worksite weight control support group that will meet weekly for the first 10 weeks and then monthly until the end of the 6-month intervention
Other: Weight loss intervention
Menu-based recommendations to consume a high fiber, low glycemic load diet with education on nutrition and behavior change.
Experimental: Control Group (delayed intervention)
At the end of the study period, subjects will receive a 2-month structured intervention that will provide all of the resources and materials given to the intervention worksite as well as weight control support groups for employees interested in losing weight.
Other: Weight loss intervention
Menu-based recommendations to consume a high fiber, low glycemic load diet with education on nutrition and behavior change.
