Rural Women Connecting for Better Health
22 novembre 2016 aggiornato da: University of Kansas Medical Center
Group Phone-Based Weight Control for Rural Breast Cancer Survivors
Women who are obese at breast cancer diagnosis have a 1.5 to 2.5 increased risk of recurrence and death compared to their normal weight counterparts.
Moreover, weight gain and decreased physical activity are common after diagnosis and also increase the likelihood of breast cancer recurrence and death.
Rural women suffer from health disparities in breast cancer diagnosis and treatment.
Women of the most rural counties also have the highest prevalence of obesity compared to urban women.
To address these disparities, the overarching objective of this proposal is to develop a clinically effective and cost efficient strategy for delivering a weight control intervention to rural breast cancer survivors.
Group phone-based treatment via conference call is a novel treatment delivery approach that the investigators have shown to be effective for initial weight loss among rural breast cancer survivors and more effective than the standard individual phone-based approach among rural women.
This innovative method of providing group treatment addresses access barriers in rural areas and may be especially ideal for rural breast cancer survivors because it provides social support in conjunction with a level of anonymity.
However, the impact of group phone counseling during extended care for weight loss maintenance beyond 6 months remains unknown.
Weight loss maintenance is the more challenging phase of treatment when weight regain is common, and this regain presents a potential risk for breast cancer recurrence.
This randomized controlled trial will evaluate the effects of group phone-based treatment for weight loss maintenance among rural breast cancer survivors, compared to an established mail-based education comparison condition, subsequent to a 6 month group phone-based weight loss phase for both conditions.
In addition to the intervention impact on weight loss maintenance, the study will provide estimates of incremental cost-effectiveness per kg loss between the two conditions and the impact on secondary outcomes including quality of life, breast cancer risk biomarkers, dietary intake, and physical activity.

Descrizione dettagliata
Phase 1 - Weight Loss (0-6 months)
- Weekly group phone counseling sessions for all participants (12-14 women per group) via conference call for 26 consecutive weeks
- Low-calorie, low-fat diet recommended, including 2 pre-packaged entrees, five one-cup servings of fruits and vegetables and meal replacement shakes (provided free of charge)
- Physical activity program program recommended, beginning with 15 minutes per day, 3 days a week, working toward a goal of 225 minutes a week
- Experienced group counselor facilitates all sessions
Phase 2 - Weight Loss Maintenance (6-18 months)
- Participants randomized to either group phone counseling or mail-based comparison with no phone counseling
- Weight loss maintenance group condition includes 26 bi-weekly phone sessions, while mail-based comparison includes 26 bi-weekly newsletters in the mail
- Focus is on problem-solving
Phase 3 - Transition to Self-Reliance (18-24 months)
- Lasts from 18-24 months
- No sessions or newsletter mailings
- Participants are encouraged to continue to self-monitor throughout this period

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Group (GRP) phone counseling
The group phone counseling includes 26 bi-weekly phone sessions from 6 to 18 months and focuses on group problem-solving.
Women continue in the same group as in weight loss intervention phase.
|
Bi-weekly phone counseling sessions from 6 - 18 months
|
|
Comparatore attivo: Mail-based Comparison Condition
Participants in this group will receive a newsletter by mail every other week for 12 months starting after the initial 6 month weight loss period.
The newsletters will provide problem-solving tips and will review nutrition and physical activity information.
|
Bi-weekly newsletter mailings from 6 - 18 months
