Djuric Z, Mirasolo J, Kimbrough L, Brown DR, Heilbrun LK, Canar L, Venkatranamamoorthy R, Simon MS. A pilot trial of spirituality counseling for weight loss maintenance in African American breast cancer survivors. J Natl Med Assoc. 2009; 101(6): 552-564.PubMed ID: 19585923
To develop a counseling method that would assist African American breast cancer survivors with weight loss maintenance.
- Females who had been diagnosed with stage I, II, or IIIA breast cancer within the last 10 years and who identified themselves as African American
- BMI 30 to 45kg/m2
- Completed chemotherapy or radiation therapy at least three months previous (with the exception of tamoxifen)
- Between the ages of 18 and 70 years
- Willing and able to follow diet and exercise recommendations
- Having spiritual influences in their lives as determined from a spirituality index screening questionnaire
- Not presently on a special diet for a medical condition or currently participating in a formal weight reduction program.
- A low score of three or more of the items on the spirituality screening index
- Women with a recurrence, a second primary tumor or other history of malignant tumors.
- Direct solicitation of clinic patients by their providers
- Presentations and mailings to an AA breast cancer support group
- Community advertising through a local newspaper
- Brochures placed in the Karmanos Cancer Institute breast care clinic.
Randomized controlled trial (pilot study).
Implied with measurements.
- Dietitian led counseling for weight loss maintenance
- Spirituality and dietitian counseling for weight loss maintenance
- Dietitian-led counseling was individualized and completed by telephone
- Free Weight Watchers coupons were provided to all participants for 18 months.
- Wilcoxon matched pairs tests were used to assess pre- and post-intervention changes within a single group
- Mann-Whitney test or Wilcoxon matched pairs test was used for comparing continuous variables between two study groups
- Kruskal-Wallis test was used to compare continuous variables across three groups
- Fisher's exact test was used to compare categorical variables across three groups
- Spearman rank correlations were computed between select pairs of continuous variables.
Timing of Measurements
- Measurements were made at baseline.
- At subsequent visits (six,12 and 18 months) a health update questionnaire was administered to capture any changes.
- Body weight was measured to the nearest quarter pound in light clothing without shoes using a health-o-meter professional beam scale
- Height was measured without shoes while standing on a stadiometer
- Hip and waist measures were obtained without restrictive garments to the nearest 0.1cm.
- RD-led counseling was provided to all subjects for 18 months and done in person at baseline, six- and 12-month visits with telephone contacts
- Weight watchers coupons were provided for free weekly attendance throughout the study
- Subjects asked to decrease fat to 20% to 25% of calories and to keep protein at 20% of calories
- Subjects also asked to exercise at least 30 minutes most days each week (at least five days) using their preferred mode of exercise)
- Subjects were instructed to take 10,000 steps a day and were provided pedometers for self-monitoring. They were also asked to keep a log of time spent on exercise.
- Spiritual counseling was done by a counselor with a Master's degree in counseling psychology and a certificate in biblical counseling
- Contacts with the counselor were by phone and scheduled weekly for three months, biweekly for the next three months and then monthly
- Subjects were taught to use daily meditation, daily readings and recording of thoughts in a journal
- Reflection journal was used to develop understanding between experiences and feelings and making sense of those feelings that can affects faith
- Physical activity patterns were captured using Stanford seven-day physical activity recall
- Spiritual well-being questionnaire was administered
- Block food frequency questionnaire was administered at beginning and end of study
- Log of all spiritual influences not related to study before assessment visits at six, 12, and 18 months.
- Health status questionnaire captured demographic information, gynecological history, medical history and body weight at baseline
- Cancer diagnosis and treatment information was obtained from oncologist notes.
- Initial N: 81 women contacted the study initially. 31 enrolled and 24 were randomized after six months
- Attrition: 22 total (11 in the Dietitian only group and 11 in the Spirituality + Dietitian only group)
- Age: 18 to 70 years
- Ethnicity: African American
- Anthropometrics: No significant differences between groups at baseline
- Location: Wayne State University and greater Detroit area.
- Weight loss in the study was modest, with a mean of 2% at baseline weight at six months (SD, 5.7; N=24) and weight loss from baseline to six months did not differ significantly by diet arm assignment being 2.5% in RD-only arm and 1.5% in the spirituality arm
- The sub-scale of the well-being questionnaire indicated that the mean overall score at baseline for spirituality in this study (mean 40.0, SD, 5.9; N=31) and there was no significant difference in mean score by diet arm.
Mean CES-D scores improved in both study arms indicated by a lower score with a slightly greater improvement in the spirituality arm vs. the RD-only arm.
The spirituality counseling framework may be further refined and useful for other health promotion studies with African American populations.

Limitations of the study include the small sample size and very modest initial weight loss, which made examination of weight loss maintenance difficult. Another limitation is that the spirituality counseling was administered by telephone, which may be less effective than in person counseling.
