Exploring health behaviors, quality of life, and support needs in African-American prostate cancer survivors: a pilot study to support future interventions.

PURPOSE: Prostate cancer incidence and mortality rates are highest among African-American men. Comorbidity burden and quality of life (QOL) challenges are also high. Many factors drive these differences; health behaviors are important modifiable contributors. Studies document positive results for lifestyle interventions targeting NHW prostate cancer survivors, but inclusion of African-Americans is limited. We conducted an exploratory mixed-methods study with AAPCS to inform the development of a culturally relevant lifestyle intervention. METHODS: Twenty-two AAPCS completed questionnaires and a discussion group on dietary and physical activity patterns, QOL, and unmet needs related to lifestyle changes. RESULTS: Seventy-five percent of the participants were overweight or obese, 82% had physical activity patterns considered insufficiently active and only 10% did resistance training at least twice weekly in accordance with current survivorship guidelines. Diets were high in saturated fat and sugar, low in fiber, fruit, and vegetable intake. PROMIS-29 scores indicated that AAPCS had worse physical functioning, pain interference, and sexual functioning, but less social isolation compared to the general population. Compared to other prostate cancer survivors, participants reported poorer status on all domains. Qualitative data highlighted barriers to healthy lifestyles including access, knowledge, and skills, as well as motivators including health benefits and building strength to feel more "manly." Participants shared high interest in programs to exercise, learn about affordable healthy eating, and bring survivors together to discuss survivorship issues. CONCLUSIONS: Lifestyle interventions targeting AAPCS are warranted. To increase impact of these efforts, consideration of environmental, cultural, and survivor contexts will be key.

Comparative Effectiveness Trial of an Obesity Prevention Intervention in EFNEP and SNAP-ED: Primary Outcomes.

There is a need to disseminate evidence-based childhood obesity prevention interventions on a broader scale to reduce obesity-related disparities among underserved children. The purpose of this study was to test the comparative effectiveness of an evidence-based obesity prevention intervention, Hip-Hop to Health (HH), delivered through Expanded Food and Nutrition Education Program (EFNEP) and the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) versus the standard curriculum delivered by the programs (Standard Nutrition Education (NE)). A nonequivalent control group design was delivered to compare the effectiveness of HH to NE on weight gain prevention and health behavior outcomes at EFNEP and SNAP-Ed sites. One hundred and fifty-three caregiver-child dyads (n = 103 in the HH group; n = 50 in the NE group) participated in the study. HH is an evidence-based dietary and physical activity intervention for low-income preschool children. The NE curriculum provided lessons for children that are consistent with the Dietary Guidelines for Americans 2010. Data were collected on demographics, anthropometrics, and behavioral variables for parent-child dyads at baseline and postintervention. Mixed model methods with random effects for site and participant were utilized. No differences in child or caregiver diet, physical activity, or screen time by group were found. No between-group differences in child BMI z-score were found; however, caregivers in the HH group lost significantly more weight than those in the NE group. Results from this trial can inform future dissemination efforts of evidenced-based programs for underserved families.

A feasibility study of breast cancer genetic risk assessment in a federally qualified health center.

BACKGROUND: The US Preventive Services Task Force (USPSTF) endorses routine screening for genetic risk of breast and/or ovarian cancer as a component of primary health care. Implementation of this recommendation may prove challenging, especially in clinics serving disadvantaged communities. METHODS: The authors tested the feasibility of implementing the USPSTF mandate at a federally qualified health center (FQHC) to identify women who were eligible for genetic counseling (GC). A 12-month usual-care phase was followed by a 12-month intervention phase, during which time cancer genetic risk assessment (CGRA) was systematically performed for all women aged 25 to 69 years who presented for an annual examination. Women who were eligible for GC were recruited to participate in the study. RESULTS: After initiating CGRA, 112 women who were eligible for GC consented to study participation, and 56% of them received a referral for GC from their primary care physician. A subgroup of 50 participants were seen by the same primary care physician during both the usual-care and intervention phases. None of these patients was referred for GC during usual care, compared with 64% after the initiation of CGRA (P < .001). Only 16% of referred participants attended a GC session. CONCLUSIONS: Implementing USPSTF recommendations for CGRA as a standard component of primary health care in FQHCs is feasible and improves referral of minority women for GC, but more work is needed to understand the beliefs and barriers that prevent many underserved women from accessing cancer genetic services.

Repurposing existing medications as cancer therapy: design and feasibility of a randomized pilot investigating propranolol administration in patients receiving hematopoietic cell transplantation.

BACKGROUND: Repurposing existing medications for antineoplastic purposes can provide a safe, cost-effective, and efficacious means to further augment available cancer care. Clinical and preclinical studies suggest a role for the ß-adrenergic antagonist (ß-blocker) propranolol in reducing rates of tumor progression in both solid and hematologic malignancies. In patients undergoing hematopoietic cell transplantation (HCT), the peri-transplant period is a time of increased activity of the ß-adrenergically-mediated stress response. METHODS: We conducted a proof-of-concept randomized controlled pilot study assessing the feasibility of propranolol administration to patients between ages 18-75 who received an autologous HCT for multiple myeloma. Feasibility was assessed by enrollment rate, tolerability, adherence, and retention. RESULTS: One hundred fifty-four patients underwent screening; 31 (20%) enrolled in other oncology trials that precluded dual trial enrollment and 9 (6%) declined to enroll in the current trial. Eighty-nine (58%) did not meet eligibility requirements and 25 (16%) were eligible; of the remaining eligible patients, all were successfully enrolled and randomized. The most common reasons for ineligibility were current ß-blocker use, age, logistics, and medical contraindications. 92% of treatment arm patients tolerated and remained on propranolol for the study duration; 1 patient discontinued due to hypotension. Adherence rate in assessable patients (n = 10) was 94%. Study retention was 100%. CONCLUSIONS: Findings show that it is feasible to recruit and treat multiple myeloma patients with propranolol during HCT, with the greatest obstacle being other competing oncology trials. These data support further studies examining propranolol and other potentially repurposed drugs in oncology populations. TRIAL REGISTRATION: This randomized controlled trial was registered at clinicaltrials.gov with the identifier NCT02420223 on April 17, 2015.

Mediation of Racial and Ethnic Disparities in Estrogen/Progesterone Receptor-Negative Breast Cancer by Socioeconomic Position and Reproductive Factors.

Hispanic and non-Hispanic black breast cancer patients are more likely than non-Hispanic white patients to be diagnosed with breast cancer that is negative for estrogen and progesterone receptors (ER/PR-negative). This disparity might be transmitted through socioeconomic and reproductive factors. Data on 746 recently diagnosed breast cancer patients (300 non-Hispanic white, 303 non-Hispanic black, 143 Hispanic) were obtained from the population-based Breast Cancer Care in Chicago Study (Chicago, Illinois, 2005-2008). Income, educational level, and census tract measures of concentrated disadvantage and affluence were combined into a single measure of socioeconomic position (SEP). Parity and age at first birth were combined into a single measure of reproductive factors (RPF). We constructed path models to estimate direct and indirect associations of SEP and RPF, and we estimated average marginal controlled direct associations. Compared with non-Hispanic white patients, non-Hispanic black patients and Hispanic patients were more likely to have ER/PR-negative disease (28% and 20% for non-Hispanic black patients and Hispanic patients, respectively, vs. 12% for non-Hispanic white patients; P ≤ 0.001). The ethnic disparity in ER/PR-negative breast cancer (prevalence difference = 0.13, 95% confidence interval: 0.07, 0.18) was reduced by approximately 60% (prevalence difference = 0.05, 95% confidence interval: -0.04, 0.13) after control for SEP and RPF. At least part of the ethnic disparity in the aggressiveness of breast tumors might be transmitted through social influences on tumor biology.

Health Behavior and Weight Changes Among Ethnic and Racial Minority Preschoolers and Their Parents: Associations Across 1 Year.

OBJECTIVE: To determine whether parent health behavior changes and feeding practices were associated with child changes in body mass index z-score and related health behaviors over the course of 1 year. METHODS: Anthropometric data from 590 child-parent dyads of ethnic/racial minority groups were collected at baseline, 14 weeks (postintervention), and 1-year follow-up. Additionally, parent screen time and feeding practices and child dietary consumption, diet quality, physical activity, and screen time were collected. RESULTS: Random effects growth models revealed that changes in child screen time moved in tandem with parent screen time from baseline to 14-week postintervention and from postintervention to 1-year follow-up. Greater parental monitoring predicted greater reduction in child calorie consumption at 1 year. CONCLUSIONS: Future studies should include innovative ways to explicitly involve parents in prevention efforts.

Breast Cancer Risk Assessment Among Low-Income Women of Color in Primary Care: A Pilot Study.

PURPOSE: The US Preventive Services Task Force recommends identifying candidates for breast cancer (BC) chemoprevention and referring them for genetic counseling as part of routine care. Little is known about the feasibility of implementing these recommendations or how low-income women of color might respond to individualized risk assessment (IRA) performed by primary care providers (PCPs). METHODS: Women recruited from a federally qualified health center were given the option to discuss BC risk status with their PCP. Comprehensive IRA was performed using a software tool designed for the primary care environment combining three assessment instruments and providing risk-adapted recommendations for screening, prevention, and genetic referral. Logistic regression models assessed factors associated with wanting to learn and discuss BC risk with PCP. RESULTS: Of 237 participants, only 12.7% (n = 30) did not want to discuss IRA results with their PCP. Factors associated with lower odds of wanting to learn results included having private insurance and reporting ever having had a mammogram. Factors associated with higher odds of wanting to learn results included older age (50 to 69 years) and increased BC worry. For all women wishing to learn results, IRA was successfully completed and delivered to the PCP immediately before the encounter for incorporation into the well-visit evaluation. CONCLUSION: Incorporation of US Preventive Services Task Force recommendations as part of routine primary care is feasible. Interest in IRA seems high among underserved women. This approach warrants further investigation as a strategy for addressing disparities in BC mortality.

Retaining traditionally hard to reach participants: Lessons learned from three childhood obesity studies.

Retaining underserved populations, particularly low-income and/or minority participants in research trials, presents a unique set of challenges. In this paper, we describe the initial retention strategies and enhanced the retention strategies over time across three childhood obesity prevention trials. Hip-Hop to Health Jr. (HH) was a randomized controlled trial (RCT) testing a preschool-based obesity prevention intervention among predominately African-American children. Retention was 89% at 14-weeks, 71% at 1-year, and 73% at 2-year follow-up. Primary retention strategies for HH included: 1) collaboration with a community-based organization to enhance program credibility; 2) continuity of data collection locations; 3) collecting detailed contact information and provision of monetary compensation; and 4) developing a detailed tracking/search protocol. In a follow-up trial, Hip-Hop to Health Jr. Obesity Prevention Effectiveness Trial (HH Effectiveness), 95% of participants completed assessment at 14 weeks and 88% completed assessment at 1 year. For this trial, we emphasized staffing continuity in order to enhance participant relationship building and required data collection staff to have relevant community service experience. In a third study, we assessed dietary quality among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) across three time points following the WIC food package shift instituted nationally in 2009. Retention rates were 91% at 12 months and 89% at 18 months. For our WIC\ study, we augmented retention by developing a home data collection protocol and increased focus on staff diversity training. We conclude with a summary of key strategies and suggestions for future research.

Family-based hip-hop to health: outcome results.

OBJECTIVE: This pilot study tested the feasibility of Family-Based Hip-Hop to Health, a school-based obesity prevention intervention for 3-5-year-old Latino children and their parents, and estimated its effectiveness in producing smaller average changes in BMI at 1-year follow-up. DESIGN AND METHODS: Four Head Start preschools administered through the Chicago Public Schools were randomly assigned to receive a Family-Based Intervention (FBI) or a General Health Intervention (GHI). RESULTS: Parents signed consent forms for 147 of the 157 children enrolled. Both the school-based and family-based components of the intervention were feasible, but attendance for the parent intervention sessions was low. Contrary to expectations, a downtrend in BMI Z-score was observed in both the intervention and control groups. CONCLUSIONS: While the data reflect a downward trend in obesity among these young Hispanic children, obesity rates remained higher at 1-year follow-up (15%) than those reported by the National Health and Nutrition Examination Survey (2009-2010) for 2-5-year-old children (12.1%). Developing evidence-based strategies for obesity prevention among Hispanic families remains a challenge.

Results of a faith-based weight loss intervention for black women.

Obesity is a risk factor for a variety of chronic diseases. Although weight loss may reduce these risks, weight loss programs designed for black women have yielded mixed results. Studies suggest that religion/spirituality is a prominent component of black culture. Given this, the inclusion of religion/spirituality as an active component of a weight loss program may enhance the benefits of the program. The role of religion/spirituality, however, has not been specifically tested as a mechanism that enhances the weight loss process. This paper presents the results of "Faith on the Move," a randomized pilot study of a faith-based weight loss program for black women. The goals of the study were to estimate the effects of a 12-week culturally tailored, faith-based weight loss intervention on weight loss, dietary fat consumption and physical activity. The culturally tailored, faith-based weight loss intervention was compared to a culturally tailored weight loss intervention with no active faith component. Fifty-nine overweight/obese black women were randomized to one of the two interventions. Although the results were not statistically significant, the effect size suggests that the addition of the faith component improved results. These promising preliminary results will need to be tested in an adequately powered trial.
