LEAN: Lifestyle Education for Activity and Nutrition for a Leaner You
Study Details
Study Description
Brief Summary
Although weight loss programs are effective in the short-term, maintaining weight loss is more challenging. Regularly tracking and logging physical activity (PA) and diet is related to greater improvements in PA and diet and to greater weight loss over time. Receiving continuous real-time feedback regarding calories burned and calories consumed could enhance weight loss maintenance. This study will examine whether a device that provides such feedback, called the SenseWear armband, enhances weight maintenance.
200 overweight adults aged 18 to 65 years will be randomly assigned to one of four groups: (1) a standard behavior change weight loss group-based program (14 group sessions over a 4 month period followed by 6 phone calls over a 5 month period), (2) a standard behavior change weight loss group-based program (15 group session over a 4 month period followed by 6 phone calls over a 5 month period) combined with the armband, (3) the armband alone (training in the use of the armband and a follow up telephone call), or (4) a self-directed weight loss control group.
Participants will be recruited through USC through listserv emails, flyers, and worksite advertisements. Interested individuals will take part in a telephone screen, an orientation, a run-in visit (which includes 2 weeks of PA and dietary logging), a baseline assessment, and a randomization visit. The intervention will then take place over a 9-month period with eligible participants. Participants will take part in follow-up assessments at month 4 and 9. Assessments at all three times will include questionnaires assessing diet, PA, psychosocial factors related to diet and PA, and quality of life related measures. They will also have their fasting blood drawn to assess lipids, glucose, and insulin, and staff will measure their blood pressure, waist circumference (size), skinfold, height, and weight.

Detailed Description
Use of Electronic Feedback on Diet and Physical Activity to Enhance Weight Management Research Summary Steven N. Blair, PED, Principal Investigator
Primary Aim
Dr. Blair and the investigative team will evaluate the contribution of the BodyMedia metabolic monitoring system to weight loss within the context of a standard behavioral weight loss program, and also as a stand alone system. The BodyMedia system consists of a metabolic monitor (armband) and computer software that analyzes energy expenditure, duration and level of physical activity, and other metabolic processes in free-living conditions. The proposed study will test the following hypotheses:
-
The standard behavioral weight loss program (Standard), BodyMedia augmented program (Armband), and the Armband Alone will produce more weight loss and reduction in waist circumference over 4 months and maintain greater weight loss and reduction in waist circumference than does a usual care self-help program (Usual Care).
-
The Armband program will produce weight loss and reduction in waist circumference comparable to the Standard program over 4 months.
-
The Armband Alone program will produce weight loss and reduction in waist circumference comparable to the Standard program after 9 months.
-
The Armband program will produce weight loss and reduction in waist circumference greater than the Standard program after 9 months.
Primary Outcomes
-
Body weight
-
Waist circumference
Secondary Outcomes
-
Weekly energy expenditure in physical activity.
-
Weekly caloric intake.
-
Percent of participants losing ≥5% of baseline body weight.
-
Stages of Motivational Readiness for physical activity and diet changes.
Tertiary Outcomes
-
Blood pressure.
-
Fasting lipid profile.
-
Fasting blood glucose.
-
Fasting blood insulin
-
Quality of life.
Study Design
The design will be a randomized controlled trial with four arms:
-
Standard behavioral weight loss intervention program.
-
Armband (standard behavioral weight loss intervention program augmented by using the BodyMedia armband and monitoring system to reinforce and support making changes in these behaviors).
-
Armband Alone that includes a one-hour orientation at baseline on how to use the armband, with a one week follow-up telephone call to answer questions.
-
Usual care (self-help with a diet and physical activity manual that provides guidance on changing these behaviors).
Fifty participants will be assigned to each of the study arms. The Standard and Armband groups will participate in weekly group counseling sessions for four months. During months 5-7 study staff will contact participants weekly via email or telephone to monitor their reports of dietary and physical activity logging, and to provide counseling support as necessary. During months 8 and 9, these contacts will be monthly. For the Armband Alone group, study staff will make monthly contact by telephone or email to answer questions and provide encouragement.
Data collection for outcomes will occur at baseline, 4 months (no blood chemistry analyses will be performed at 4 months), and 9 months. Participants will be recruited into the study over several months, and all participants will have completed the follow-up (month 9) data collection by the end of the 18-month study period.

Study Results
Participant Flow
Recruitment Details | We conducted a total of 787 telephone screening interviews between February 2008 and February 2009 from the greater Columbia, South Carolina area. 197 men and women were eligible. Participants were recruited using a wide variety of techniques, including newspaper, mailers, community events, and worksite and other e-mail distributions. |
---|---|
Pre-assignment Detail | Exclusion criteria included significant weight loss (>20 lbs) in the last 6 months, elevated blood pressure (160/95 mm Hg), ailments that limited their physical activity, or serious medical conditions or other issues (e.g. pregnancy or depression) contraindicating or confounding the weight loss intervention. |

Arm/Group Description | During the first 4 months of the intervention, these participants received 14 GWL sessions based on ALED and HEED. Each session followed the ALED and HEED curriculum format with the addition of a weekly weigh-in and greater emphasis on weight loss than in the original programs. During the final 5 months participants received 6 one-on-one telephone counseling sessions to provide continued support and enhance weight loss maintenance. | These participants received all components of the GWL including the 6 one-on-one telephone counseling sessions and also received the SenseWearTM platform. | The SWA-alone group received the SenseWearTM platform consisting of the armband, a real-time wrist watch display, and access to a personalized Weight Management Solutions web account. While wearing the armband, participants received real-time feedback from the wrist watch on several outcomes (i.e. energy expenditure, minutes spent in moderate and vigorous physical activity, and steps per day). Feedback regarding energy balance was received as participants regularly uploaded their armband to the website and recorded daily energy intake and body weight to the Weight Management Solutions web account. Participants were asked to wear the armband 16 hours a day, 7 days a week. | Standard care participants received a self-directed weight loss manual based on two evidence-based programs, Active Living Every Day (ALED) and Healthy Eating Every Day (HEED). The manual's focus was to help individuals adopt a healthful eating pattern and increase their physical activity levels through the use of cognitive and behavioral strategies consistent with the Transtheoretical Model and Social Cognitive Theory. |

While wearing the armband, participants received real-time feedback from the wrist watch on several outcomes (i.e. energy expenditure, minutes spent in moderate and vigorous physical activity, and steps per day). Feedback regarding energy balance was received as participants regularly uploaded their armband to the website and recorded daily energy intake and body weight to the Weight Management Solutions web account. Participants were asked to wear the armband 16 hours a day, 7 days a week. | Standard care participants received a self-directed weight loss manual based on two evidence-based programs, Active Living Every Day (ALED) and Healthy Eating Every Day (HEED). The manual's focus was to help individuals adopt a healthful eating pattern and increase their physical activity levels through the use of cognitive and behavioral strategies consistent with the Transtheoretical Model and Social Cognitive Theory. | ||||
