Lifestyle intervention for Latina cancer survivors and caregivers: the Nuestra Salud randomized pilot trial

Use of cultural appropriateness strategies and behavioral frameworks in behavioral interventions for black and hispanic cancer survivors: a systematic review

BACKGROUND

Black and Hispanic cancer survivors experience significant inequities in supportive cancer care. Incorporating cultural appropriateness strategies and behavioral frameworks into supportive care interventions can improve cancer outcomes of Black and Hispanic survivors. This review evaluated behavioral oncology trials for Black and Hispanic cancer survivors to assess their use of cultural appropriateness strategies and behavioral frameworks.

METHODS

A systematic search was conducted across seven databases with a cutoff date of November 15, 2023: 1) PubMed, 2) Cochrane Central Register of Controlled Trials, 3) Embase, 4) Cumulative Index of Nursing and Allied Health Literature, 5) APA PsycInfo, 6) Scopus, and 7) Web of Science. Studies with Black or Hispanic cancer survivors, with or without a comparator, were included.

RESULTS

Thirty-seven trials met the inclusion criteria. Most focused on Black survivors (n = 19, 51.4%) and breast cancer survivors (n = 32, 86.5%). Most were psychosocial interventions addressing quality of life or distress (n = 20, 54.1%). Culturally appropriate strategies were reported in 86.5% (n = 32) of trials, with the most common being sociocultural (n = 30, 81.1%;), constituent-involving (n = 27, 73.0%;), and linguistic (n = 20, 54.1%;). Behavioral frameworks were reported in 56.8% (n = 21) of trials, with Social Cognitive Theory (n = 10, 52.6%) and Stress and Coping Theory (n = 3, 15.8%) being the most frequent. Less than half combined cultural adaptation strategies and a behavioral framework (n = 18, 48.6%).

CONCLUSION

While most trials incorporated cultural appropriateness strategies, fewer utilized behavioral frameworks, and even fewer used both. Future research should integrate these approaches to improve cancer outcomes and address disparities.

Understanding crisis needs among family caregivers of patients in critical care: A qualitative analysis

BACKGROUND

Family caregivers often experience shock and disorientation when a patient is admitted to critical care. Developing interventions to assist caregivers during this crisis requires a more in-depth understanding of their needs.

OBJECTIVE

Our aim was to understand family caregivers' needs during a patient's critical care admission and early hospitalisation and differences in needs by caregiver anxiety level.

METHODS

We conducted a descriptive mixed-method study. Forty semistructured interviews were conducted with family caregivers of mechanically ventilated critical care patients. The Hospital Anxiety and Depression Scale was also administered. Crisis theory was used to guide this analysis. The data were analysed by content analysis and then stratified by anxiety level to examine differences across groups. Consolidated Criteria for Reporting Qualitative Research were followed.

SETTING

Two intensive care units at a large, tertiary academic medical centre were a part of this study.

FINDINGS

Caregivers at all anxiety levels described needs involving information and emotional processing, social support, and self-care, with differences across anxiety groups. Caregivers with anxiety and borderline anxiety expressed limited capacity to think past the current moment, whilst caregivers with low anxiety actively used information to consider next steps and prepare others. Emotional processing appeared more limited in the anxiety and borderline-anxiety groups. Whilst most caregivers reported receiving some degree of social support, some caregivers with anxiety noted family tension, whilst caregivers with borderline and low anxiety had a wider variety of supportive relationships. Caregivers with anxiety reported distress influenced their self-care, whilst caregivers with borderline and low anxiety received tangible help from other family members for self-care.

CONCLUSION

Family caregivers of critical care patients experience needs during early hospitalisation, although the specific needs differ by caregiver anxiety level.

Dietary Quality and Intake of Cancer Caregivers: A Systematic Review of Quantitative Studies and Recommendations for Future Research

AIMS

As more people live with and beyond a cancer diagnosis, the role of informal caregivers becomes increasingly vital. Despite emotional, physical, and financial challenges, the impact of caregiving on health behaviors, including diet, has been largely overlooked. This systematic review synthesized quantitative evidence on dietary quality and intake among cancer caregivers.

METHODS

Five databases (CINAHL, Embase, PubMed, PsycINFO, Web of Science) were searched in February 2024 using keywords including cancer, caregiver, and diet. Articles published since 2013 that quantitatively assessed the dietary quality or intake of cancer caregivers were eligible. Articles were independently screened in Rayaan by two authors, with discrepancies resolved by a third author. Data on study design, aims, methods, sample characteristics, and results were extracted and summarized using descriptive analyses. One author performed data extraction, with a second author reviewing results for accuracy.

RESULTS

Of 12,584 records identified, 22 met eligibility criteria. Most studies were conducted in the United States (68%), were cross-sectional (77%), and included caregivers who were partners (68%) of people with cancer. Four (18%) studies reported on energy or nutrient intakes, 13 (59%) reported on food or food group intakes, and 10 (45%) reported on diet quality or dietary patterns. Results varied widely due to differences in assessment methods used. Dietary changes due to caregiving were described in 8 (36%) studies, mostly using retrospective self-reported data. Negative, positive, and no dietary changes were reported in 7 (32%), 5 (23%), and 4 (18%) studies, respectively. Two (9%) studies did not specify the direction of change. Eight (36%) studies assessed adherence to dietary recommendations, with mixed results.

CONCLUSIONS

Evidence of the dietary quality and intake of cancer caregivers is inconclusive. Larger, longitudinal studies using validated measures, repeated observations, and comparison to dietary guidelines are needed to better understand the impacts of caregiving on diet.

Social Support, Diet, and Physical Activity among Latina/Hispanic Women Breast Cancer Survivors

Diet and physical activity guidelines for cancer survivorship are less likely to be followed by populations of minority cancer survivors, such as Latina/Hispanic women, compared to non-Hispanic White women. It is important to understand psychosocial mechanisms that may increase adherence to healthy lifestyle habits, especially in populations at risk for poorer cancer outcomes. This cross-sectional study examined the relationships between overall social support (SS) and SS from three sources (family, friends, and significant other) with diet (fruit and vegetables, fat, energy density, and diet quality), and moderate-to-vigorous physical activity (MVPA) behaviors in Latina/Hispanic women with a history of breast cancer (n = 85; M age = 55.2; SD = 9.2). Linear regression models and odds ratios were used to examine associations and adjusted for age, income, and acculturation. Family, significant other, and total SS were positively related to total fruit and vegetable intake but SS from friends was not. Higher levels of SS from all sources were each related to a low energy density diet. A higher quality diet was only related to SS from family. SS was not related to fat intake or MVPA. Higher SS from family and a significant other were associated with higher odds of meeting the fruit/vegetable guidelines; (family, OR = 3.72, 95% CI [1.21, 11.39]; significant other, OR = 3.32, 95% CI [1.08, 10.30]). Having more SS from family or a significant other may contribute to Latina/Hispanic women breast cancer survivors meeting national guidelines for a diet high in fruits and vegetables and low in energy density.

Expanding active living after cancer to underserved cancer survivors and their caregivers

BACKGROUND

Physical activity improves physical and psychological health in cancer survivors. This study evaluated Active Living After Cancer (ALAC), a community-based program to improve physical activity, physical function, and quality of life (QOL) in minority and medically underserved cancer survivors and their caregivers.

METHODS

Participants completed 12 weekly ALAC sessions and assessments of physical activity, physical functioning, and QOL at baseline and follow-up (week 12). Paired samples t tests were used to assess changes in outcomes over time.

RESULTS

A total of 540 cancer survivors (mean age = 61.1 [SD = 11.3] years) and 87 caregivers (mean age = 62.3 [SD = 13.1] years) were enrolled. Most were women (91.4%), Hispanic (61.1%) or non-Hispanic Black (19.3%), and medically underserved (86.4%). The percent of cancer survivors meeting physical activity recommendations increased from 28.9% to 60.2% (d = 0.75), and the number of sit-to-stand repetitions in a 30-second period increased from 12.3 to 14.3 (d = 0.39) from 0-12 weeks. Cancer survivors reported statistically significant improvements in physical (t score Δ = 1.7, d = 0.06) and mental (t score Δ = 2.3, d = 0.31) health-related QOL. Caregivers also improved their physical activity, physical function, and QOL, and there were no statistically significant differences between breast and other cancer survivors and between cancer survivors and caregivers.

CONCLUSIONS

The ALAC program demonstrated increased physical activity, physical function, and QOL in medically underserved cancer survivors and their caregivers. Furthermore, ALAC was successfully implemented by community partners and serves as a good model for reaching medically underserved cancer survivors and improving survivorship. Additional efforts are warranted to further extend reach, improve cancer survivorship, and reduce cancer health disparities among underserved cancer survivors.

A sequential multiple assignment randomized trial of symptom management for cancer survivors during treatment and their informal caregivers

CONTEXT

Many cancer survivors and their informal caregivers experience multiple symptoms during the survivor's treatment.

OBJECTIVE

Test relative effectiveness and optimal sequencing of two evidence-based interventions for symptom management.

METHODS

In this sequential multiple assignment randomized trial (SMART), survivors of solid tumors with elevated depression or anxiety and their caregivers as dyads were initially randomized after baseline assessment in a 3:1 ratio to the Symptom Management and Survivorship Handbook (SMSH, N = 277 dyads) intervention or SMSH plus 8 weeks of telephone interpersonal counseling (TIPC, N = 97 dyads). After 4 weeks, survivors who were not responding (no improvement or worsening score on depression and/or anxiety item) to SMSH only and their caregivers were re-randomized to continue with SMSH alone (N = 44 dyads) to give it more time or to SMSH + TIPC (N = 44 dyads). Mixed effects and generalized linear models compared severity of depression, anxiety, and a summed index of 16 other symptoms over weeks 1-13 and week 17 between randomized groups and among three dynamic treatment regimes (DTRs). Dyads received SMSH only for 12 weeks (DTR1); SMSH for 12 weeks with 8 weeks of TIPC added from week 1 (DTR2); and SMSH for 4 weeks followed by the combined SMSH + TIPC for 8 weeks if no response at 4 weeks (DTR3).

RESULTS

Survivors randomized initially to SMSH alone had significantly lower anxiety over weeks 1-13 compared to those randomized to the combined SMSH + TIPC. In comparing DTRs, survivor's anxiety was significantly lower at week 13 for DTR1 compared to DTR2 with no other main effects for survivors or caregivers. Exploratory moderation analyses indicated a potential benefit of adding TIPC for caregivers of non-responders with elevated baseline symptoms.

CONCLUSION

SMSH + TIPC did not result in better symptom outcomes at week 17 than SMSH alone. Lower intensity SMSH may improve depression and anxiety symptoms for most survivors and their caregivers.

Effect of a metaverse multimodal rehabilitation intervention on quality of life and fear of recurrence in patients with colorectal cancer survivors: A randomized controlled study protocol

Background

Regular rehabilitation during or after cancer treatment can bring numerous benefits to colorectal cancer survivors. However, there is a lack of convenient and mobile rehabilitation support systems tailored specifically for this group. The metaverse, as a virtual reality environment, offers an innovative platform for implementing rehabilitation. Hence, our study aims to develop a metaverse-based multimodal rehabilitation program and assess its effects on enhancing outcome measures such as quality of life in colorectal cancer patients.

Methods and analysis

This study was designed as a randomized, single-blind controlled trial design featuring two arms: a rehabilitation group and a conventional care group. Sixty colorectal cancer survivors who have undergone curative surgery followed by adjuvant chemotherapy will be recruited for this study. The intervention will take place within the metaverse over a 4-week period. Assessments will be conducted at baseline and after 4 weeks. The intervention is grounded in the behavior change wheel framework and encompasses dietary intervention, exercise intervention, psychological support, and behavior management. Through the implementation of diverse strategies such as training, education, and motivation, our objective is to enhance patients' capacity, opportunities, and motivation, ultimately fostering healthy behaviors. Outcome measures will encompass quality of life, fear of recurrence, and lifestyle.

Results

The analysis includes statistical description and inference. Quantitative data will be summarized using mean ± standard deviation for normally distributed data and medians with percentiles for non-normally distributed data. Categorical data will be presented as frequencies and percentages. Statistical tests will detect significant differences between pre- and post-intervention periods. Subgroup analysis will explore CRC stage, age, and gender in relation to outcome measures to identify factors affecting intervention efficacy.

Conclusions

The findings from this research will offer valuable insights and practical implications for the implementation of remote interventions and family-based interventions in the context of colorectal cancer survivorship.

A Systematic Review of Dietary Interventions for Cancer Survivors and Their Families or Caregivers

Family or caregiver engagement has the potential to support healthy dietary changes among cancer survivors. However, little is known about these family- or caregiver-involved dietary interventions and their effects. This systematic review aimed to identify the behavior change techniques (BCTs) used in dietary interventions for cancer survivors and their families or caregivers and to synthesize intervention effects on dietary and health outcomes. Following the PRISMA guidelines, we conducted systematic searches in three databases and identified 12 trials (16 peer-reviewed manuscripts) for inclusion in this review. Data were extracted from these manuscripts and the BCT taxonomy was used to identify the BCTs. A total of 38 BCTs were identified from 12 trials, 13 of which were used in at least half of the 12 trials. Ten studies reported significant intervention effects on health outcomes (e.g., adiposity) and six suggested significant improvements in dietary behaviors (e.g., fruit and vegetable intake). Overall, this review found that family- or caregiver-involved interventions for cancer survivors significantly improved dietary and health outcomes. Future research should identify BCTs particularly for dietary changes and develop effective dyadic strategies to facilitate diet-related interactions between survivors and their families or caregivers to enhance their engagement in healthy diets.

A Scoping Review to Explore the Potential Benefits of Nutrition Interventions for Latino/a Adult Cancer Survivors in the US

Despite evidence for the role of healthy diets in preventing cancer, little is known about how nutrition can support positive health outcomes after a cancer diagnosis for Latino/a cancer survivors in the United States (U.S.). The purpose of this scoping review is to understand the potential benefits of nutrition interventions in supporting healthy survivorship among Latino/a cancer survivors in the U.S. A team compiled, evaluated, and summarized the available evidence. Potentially relevant studies were identified from a comprehensive search of peer-reviewed databases and the gray literature. Eligible studies included Latino/a adult cancer survivors with a nutrition education, dietary change, or behavioral intervention; and a nutrition-related health outcome. Data were extracted and summarized using tables. The review included 10 randomized controlled trials, with samples or subsamples of Latino/a cancer survivors. Interventions mostly focused on breast cancer survivors. The results showed some evidence that dietary behaviors, like fruit and vegetable intake, were related to positive outcomes, like a decreased risk of cancer (through changes in DNA methylation), decreased risk breast cancer recurrence (through changes in inflammatory biomarkers), or improved perception of health status. The findings highlight a need for community-engaged and culturally relevant nutrition interventions for Latino/a adults, especially for rural communities; and innovative intervention approaches, including m/ehealth approaches with long-term follow-up.

George SM, Crane TE. Feasibility and Acceptability of a Text Message Intervention to Promote Adherence to Nutrition and Physical Activity Guidelines in a Predominantly Hispanic Sample of Cancer Survivors and Their Informal Caregivers: Results from a Pilot Intervention Trial

Hispanic cancer survivors face unique barriers to meeting American Cancer Society (ACS) nutrition and physical activity guidelines, which reduce the risk of cancer recurrence and mortality and improve quality of life. This pilot intervention trial evaluated the feasibility and acceptability of a two-week ACS guideline-based nutrition and physical activity text message intervention in a predominantly Hispanic sample of cancer survivors and their informal caregivers. A mixed methods approach was used to assess feasibility and acceptability of the intervention. Feasibility and acceptability were measured by meeting a-priori cut-offs of >80% for recruitment, retention, and text message response rate. Participants also completed a semi-structured exit interview by telephone that assessed intervention components. Thirteen cancer survivors and six caregivers (n = 19) participated in this pilot study; 78% self-identified as Hispanic. Mean time since treatment completion for survivors was 11.9 years (SD 8.4), and 67% had breast cancer. Cancer survivors had a higher acceptability rate for physical activity (94%) compared to nutrition messages (86%), whereas equal acceptability rates were observed for both types of messages among caregivers (91%). Texting interventions are a feasible, acceptable, and a cost-effective strategy that have the potential to promote lifestyle behavior change among Hispanic cancer survivors and caregivers.

Methodology for Analyzing Qualitative Data in Multiple Languages

BACKGROUND

Translation strategies are commonly used for qualitative interview data to bridge language barriers. Inconsistent translation of interviews can lead to conceptual inequivalence, where meanings of participants' experiences are distorted, threatening scientific rigor.

OBJECTIVES

Our objective is to describe a systematic method developed to analyze multilingual, qualitative interview data while maintaining the original language of the transcripts.

METHODS

A literature review of translation strategies, cross-language, and multilingual qualitative research was conducted. Combined with criteria for qualitative content analysis and trustworthiness, the methodology was developed and used for a qualitative descriptive study.

RESULTS

The study had interview data in both English and Spanish. The research team consisted of both native Spanish and English speakers, who were grouped based on language. Verbatim transcription of data occurred in the original languages. All codes were kept in English, allowing the research team to view the data set as a whole. Two researchers within each group coded each transcript independently before reaching a consensus. The entire research team discussed all transcripts, and finally, major themes were determined. Participants' quotes remained in the original language for publication, with an English translation included when needed.

DISCUSSION

Analyzing transcripts in the original language brought forth cultural themes that otherwise may have been overlooked. This methodology promotes conceptual equivalence and trustworthiness that is paramount in cultural, linguistic, and social determinants of health research to advance health equity.

Multiple Levels of Influence on Lifestyle Behaviors among Cancer Survivors in Racial and Ethnic Minority Groups: A Systematic Review

Objective

This systematic review aimed to provide a critical summary of studies of physical activity (PA) and diet among racial/ethnic minority cancer survivors. Guided by the socio-ecological model, we identified factors across multiple levels-individual, family/social support, provider/team, and organization/local community/policy environment-that affect PA and diet among racial/ethnic minority survivors.

Methods

We searched the Ovid MEDLINE, EBSCO CINAHL, Ovid PsycInfo, and PubMed databases. We extracted the behavior of focus (i.e., PA and diet), cancer type, race/ethnicity, and the level(s) of influence (and the corresponding factor(s)), and each eligible study investigated individual (e.g., demographic characteristics, psychological factors), family/social support, provider/team (e.g., healthcare provider recommendations), and organization/local community/policy environment (e.g., neighborhood/social environment).

Results

Of 1,603 studies identified, 23 unique studies were eligible. Most studies included breast cancer survivors (n = 19) and Black survivors (n = 13). Seventeen studies assessed associations between PA and factors at the level of the individual (16 studies), family/social support (two studies), provider/team (one study), or organization/local community/policy environment (four studies). Eleven studies assessed associations between diet and factors at the level of the individual (11 studies), family/social support (two studies), provider/team (one study), or organization/local community/policy environment (two studies). Only five studies simultaneously investigated factors across multiple levels. Most demographic and cancer-related factors were not associated with PA or diet. Overall, factors from social-cognitive theories (e.g., self-efficacy) were positively associated with PA. Less consensus was found regarding diet because fewer studies existed, and they also investigated a diverse range of eating behaviors.

Conclusions

There is a critical need for studies of PA and diet that investigate multiple levels of influence particularly for Asian American survivors, male survivors, and cancers other than breast cancer. Social-cognitive theories may help guide the designing of multilevel PA interventions for racial/ethnic minority survivors. Studies assessing overall eating quality or adherence to dietary guidelines are needed.

Diet and physical activity interventions in Black and Latina women with breast cancer: A scoping review

Background

A growing number of lifestyle interventions are being developed to promote weight loss and adoption of a healthful lifestyles among breast cancer survivors; yet Black and Latina women remain underrepresented.

Purpose

We performed a scoping review of the available peer-reviewed literature to describe and compare the content, design, methods, and primary outcomes of current diet and/or physical activity (PA) interventions after a breast cancer diagnosis among Black and Latina women.

Methods

We queried PubMed, EMBASE, CINAHL, MEDLINE, and Clinicaltrials.gov up to October 1, 2022, to identify all randomized controlled trials of diet and/or PA after diagnosis of breast cancer with a majority (>50%) of Black or Latina participants.

Results

Twenty-two randomized controlled trials were included in this review (five efficacy, twelve pilot, five on-going). Nine trials were among Latinas (two diet, four PA, and three diet/PA), six among Blacks (one PA and five diet/PA) and seven included both populations (five PA and two diet/PA), all of which examined different endpoints. Two of the five efficacy studies achieved their a priori outcome (one diet trial improved short term dietary intake; one PA trial achieved clinically significant improvements in metabolic syndrome score), both in Latinas. Eight pilot trials intervened on both diet and PA and three of them found favorable behavioral changes. Three (two for Latinas and one for Blacks) out of the nine diet and PA trials and three (all for Latinas) efficacy trials incorporated a culturally focused approach (i.e., traditional foods, music, Spanish content, bicultural health coaches, spirituality). Overall, four trials, including one efficacy trial, had one-year follow-up data, with three finding sustained behavior change. Electronic/mobile components were incorporated in five trials and one involved informal care givers. Most of the trials were geographically limited to the Northeast USA (n=8, NY, NC, DC, NJ) and Texas (n=4).

Conclusions

Most of the trials we identified were pilot or feasibility studies and of short duration, demonstrating the need for large randomized controlled efficacy lifestyle interventions among Black and Latina breast cancer survivors. Culturally tailored programing was limited but is an important component to incorporate in future trials in these populations.

Family-based psychosocial interventions for adult Latino patients with cancer and their caregivers: A systematic review

Objective

This review aimed to systematically examine the characteristics and outcomes of family-based psychosocial interventions offered to adult Latino patients with cancer and their caregivers.

Methods

We searched six databases from their inception dates through June 2022. Studies were eligible for inclusion if they (1) targeted both adult Latino patients diagnosed with cancer and their adult caregivers or reported subgroup analyses of Latino patients and caregivers; (2) included family-based psychosocial interventions; (3) used randomized controlled trial (RCT) or quasi-experimental designs; and (4) were published in English, Spanish or Portuguese. Members of our multidisciplinary team assessed the risk of bias in the reviewed studies using the Cochrane Collaboration's Risk of Bias Tool.

Results

Our database searches yielded five studies. The studies were conducted in the U.S. and Brazil. Three studies were RCTs, and two used quasi-experimental designs. The sample sizes ranged from 18 to 230 patient-caregiver dyads. These studies culturally adapted the intervention contents and implementation methods and involved bilingual interventionists. The interventions had beneficial effects on multiple aspects of psychosocial outcomes for both patients and caregivers. We also identified methodological limitations in the reviewed studies.

Conclusions

Findings from this systematic review help deepen our understanding of family-based psychosocial interventions for Latinos affected by cancer. The small number of psychosocial interventions focused on adult Latino cancer patients and their caregivers is concerning, considering that Latino populations are disproportionally burdened by cancer. Future research needs to design and evaluate culturally-appropriate interventions to support Latino patients and families who cope with cancer.

Barriers and facilitators for adopting a healthy lifestyle among Latina cancer survivors: A qualitative descriptive study

PURPOSE

Cancer is the leading cause of death among Hispanics/Latinos in the USA. Latina cancer survivors experience higher symptom burden than other cancer survivors. A healthy lifestyle can decrease recurrent cancer risk, increase well-being, and may decrease symptom burden in cancer survivors. The purpose of this study was to explore the barriers and facilitators for adopting healthy lifestyle behaviors among Latina cancer survivors.

METHODS

Using the Health Belief Model as the theoretical framework, qualitative descriptive methodology was used for secondary analysis of data from a previously conducted randomized clinical trial. Transcripts from the telephone health coaching calls, analyzed in the original language (English or Spanish), were used for this qualitative analysis.

RESULTS

Intervention telephone call transcript data from Latina cancer survivors (n = 14) were analyzed. Major themes were as follows: Perceived susceptibility to other chronic illnesses, perceived benefits of a healthy lifestyle, and perceived barriers and facilitators of adopting a healthy lifestyle. Lack of knowledge about healthy lifestyle behaviors could prevent participants from adopting a healthy lifestyle; gaining new knowledge about healthy lifestyle behaviors was a facilitator for changing lifestyle. Family responsibility and wearable technology could both prevent and motivate the participants to adopt a healthy lifestyle.

CONCLUSION

Developing culturally appropriate interventions for Latina cancer survivors is vital to decrease symptom burden and health risks, as well as improve health outcomes in this population.

Harnessing Nutrition and Physical Activity for Breast Cancer Prevention and Control to Reduce Racial/Ethnic Cancer Health Disparities

There are well-known racial/ethnic disparities in the prevalence of obesity and physical inactivity, as well as breast cancer risk and survival. However, most of the current scientific evidence that serves as a foundation for nutrition and physical activity guidelines is based on studies conducted in predominantly non-Hispanic White populations. Similarly, exercise, diet, or lifestyle intervention trials for breast cancer prevention and survivorship are scarce in racial/ethnic minority populations. We review the current evidence for racial/ethnic disparities in obesity and breast cancer risk and survival (we are focusing on obesity, because this is considered an ASCO priority, and studies conducted in the United States), discuss the evolution of nutrition/physical activity guidelines for cancer prevention and control, and provide an overview of lifestyle interventions, including barriers and facilitators in implementation and dissemination science among minority populations underrepresented in research. There is a critical need to include racially/ethnically diverse populations in cancer prevention and control research or to specifically target minority populations in which disparities are known to exist to achieve much needed health equity.
