Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

African American (AA) women have the lowest physical activity (PA) levels, which contributes to substantial disparities in cardiovascular health and depressive symptoms. There is a need to examine ways to promote PA that are appealing, applicable to clinical practice, and cost-effective. The purpose of this clinical trial is to test the efficacy of the Women's Walking Program (WWP), consisting of a lifestyle PA prescription and "group visit" delivery model, with or without tailored telephone contacts between group visits for increasing adherence to PA and improving health outcomes. Two telephone contact strategies will be compared against a no-telephone control condition: a person-administered contact strategy using brief motivational interviewing and an automated contact strategy using a telephone computer-linked system. Group visits and telephone contacts are designed to increase adherence to lifestyle PA with an emphasis on accumulation of 3,000 steps daily over baseline. The aims of this study are (1) to compare the initial (adoption 24 weeks) and longer-term (maintenance 2nd 24 weeks) effectiveness of the WWP plus person-administered telephone contacts, WWP plus automated telephone contacts, and the WWP without telephone contacts on (a) increasing adherence to lifestyle PA, (b) improving health outcomes (aerobic fitness, body composition, depressive symptoms), (c) improving self-efficacy (confidence in one's ability to be physically active) and outcome expectations (expected benefits to being more active); and (2) to compare cost-effectiveness of the three telephone treatment conditions in relation to adherence to lifestyle PA and health outcomes.

The investigators will randomly assignment of the order of administering the three conditions to six community health care sites. These six sites are similar with respect to race, socioeconomic status, and residential mobility. The study will include 288 sedentary AA women aged 40 to 65 years who have no major signs or symptoms of cardiovascular disease (CVD); no history of myocardial infarction, stroke, or diabetics with elevated HgA1c; BP \< 160/100.

Initial screening will occur in person or over the phone. Further screening at the data collection site with an advanced practice nurse will include blood work for glucose and lipoproteins, a history and physical, and resting EKG. At baseline, 24 and 48 weeks all women who are eligible will: be given questionnaires on physical activity, health and factors that influence their physical activity; have their height, weight, waist circumference measured; and do a two minute step test. All three treatment group will attend 5 group visits every 5 weeks during adoption (first 24 weeks) and 1 booster group visit during maintenance (week 36). The group visit consists of brief individual time with a staff member followed by a group visit with motivational videotapes. All treatment groups will self-monitor their physical activity with accelerometers and enter their step data into a voice response system.

The groups receiving the automated telephone contact strategy and the group receiving the person telephone contact strategy will have the same number and spacing of the telephone contacts (nine 10- to 15-minute telephone contacts delivered every two to three weeks between group visits during adoption and two telephone contacts \[weeks 28, 43\] during maintenance). Using motivational interviewing, a nurse will tailor the telephone discussion to the person telephone contact group to match the participant's needs, experiences, barriers, motivation, and confidence. Women in the automated telephone contact group will receive an automated call with feedback on their progress based on the information they reported into the ATCL system. The automated telephone contact system will deliver feedback on progress, problem solving, goal-setting, and support. All information will be delivered in the voice of one of our staff members. The third treatment group will receive no telephone contacts between group visits.

Potential risks exist for women who have medical problems, which contraindicate physical exercise. Additional risks associated with the walking program include safety and injury. There are potential risks of infection at the site of the one time finger blood withdrawal. Potential benefits to subjects include improved aerobic fitness, blood cholesterol, body composition and blood pressure and fewer symptoms. The subjects will be given a physical activity prescription that should benefit them through life and decrease their risk for CVD.

Women will be recruited throughout the West and South side of Chicago. They will give verbal consent at the screening questionnaire and sign an informed consent at the time of the screening history and physical. They will be told that participation is voluntary, they may decline or withdraw at will at any time, and all results will be held strictly confidential.

Walking Program + motivational interviewing calls

The Women's Walking Program (WWP) core included a lifestyle PA prescription with an accelerometer for self-feedback and monitoring and 6 group visits (1 every week for 5 weeks in the 1st 24 weeks and 1 3 months later) targeted to increase lifestyle PA in AA women.

Participant in the WWP plus motivational interviewing telephone call arm receives 11 motivational interviewing telephone calls from an interventionist, with two calls in between each of the group-visits. Motivational interviewing calls are tailored to the individual and intended to sustain intervention effects between group-visits

Participants in the WWP plus automated telephone call arm receive 11 automated calls with two calls sent between each group-visit. The automated calls are intended to supplement and sustain the intervention effects of the group-visits.
