Trial Information

A Pilot Weight Control Intervention at Harvard Pilgrim Health Care (HPHC)

- All study participants must have regular access to the Internet, however, the study
will not provide this access. Participants will be randomly placed in one of two study
groups (Group 1 or Group 2).

- Group 1 participants will be asked to make 3 in-person visits, each lasting 75-90
minutes. The following information will be collected: name, mailing address, telephone
number, and email address. During the study visit, the following measurements will be
taken: height, weight, waist circumference, blood pressure and dietary patterns.

- Group 1 participants will also receive counseling around diet and physical activity
from a registered dietician and be asked to use a specialized website that will allow
them to track eating and physical activity patterns, learn new weight management
skills, interact with the dietician, and receive support from other participants.

- Group 1 will also receive 5 telephone counseling calls with a health counselor. During
the telephone calls, we will teach the participant new skills such as tracking diet and
physical activity, goal-setting and staying motivated.

- Group 2 participants will be asked to make 2 in-person visits, each lasting 75-90
minutes in length. The following information will be collected: your name, mailing
address, and telephone number. During the study visit, the following measurements will
