Food insecurity screening: A missing piece in cancer management

Food for Cancer Health Equity: A Qualitative Study Among People With Cancer Who Are Low-Income, Latino or Hispanic, Immigrant, and Individuals With Multiple Minoritized Races and Ethnicities

PURPOSE

Food insecurity is prevalent among patients with cancer. Gaps in our understanding of preferences for food assistance among Latino or Hispanic, immigrant, and people with multiple races and ethnicities limit uptake of food assistance interventions among these populations. We aimed to deeply understand the needs and preferences and barriers to food assistance intervention uptake among low-income, predominantly Latino or Hispanic, immigrant, and people with multiple races and ethnicities and cancer to inform development of tailored interventions.

METHODS

Participants were recruited among low-income adult patients with cancer who screened positive for food insecurity using the two-item Hunger Vital Sign as part of an ongoing parent randomized controlled trial evaluating a precision medicine intervention. Semi-structured interviews were conducted to assess dietary habits, barriers to food security, and preferences for intervention. Interview responses were transcribed, translated, and thematically analyzed using an inductive-deductive iterative approach.

RESULTS

Among 40 (36.4%) participants in the parent randomized trial who screened positive for food insecurity, 20 (50%) were randomly selected to participate in this study. The mean age of participants was 56 years, 17 (85%) self-identified as Latino or Hispanic, 17 (85%) identified Spanish as their preferred language, 13 (65%) reported annual household income <$34,000 in US dollars, and 12 (60%) were unemployed. Three main themes emerged: (1) individualized nutritional needs and culturally specific food preferences; (2) financial, logistical, and emotional barriers to food security; and (3) self-efficacy, autonomy, and approaches to reduce stigma in food assistance interventions.

CONCLUSION

Assessing and integrating the needs and preferences for food assistance is crucial for the development and uptake of food assistance interventions among Latino or Hispanic, immigrant, and other racial and ethnic minoritized individuals with cancer.

Integrative Oncology: Incorporating Evidence-Based Approaches for Patients With GI Cancers

Data have matured to support incorporation of integrative oncology modalities into comprehensive cancer care. Clinical practice guidelines have recently been published by ASCO for diet and exercise (2022) and use of cannabinoids and cannabis (2024) and jointly by ASCO and the Society for Integrative Oncology (SIO) for application of integrative approaches in the management of pain (2022), anxiety and depression (2023), and fatigue (2024) among adults with cancer. Following the ASCO-SIO guidelines, clinicians should recommend mindfulness-based interventions (MBIs) to patients with symptoms of anxiety or depression and MBIs and exercise for management of fatigue during or after completion of cancer treatment. We will review the basis of these recommendations and evidence to support use of other mind-body approaches, exercise, nutrition, acupuncture/acupressure, and natural products in the specific contexts of GI cancers. For example, optimizing physical activity and diet is associated with improved survival after a colorectal cancer (CRC) diagnosis, in addition to conferring symptom management benefits. We will also highlight gaps in research, including that most studies enrolling patients with GI malignancies have focused on CRC. A limitation of nonpharmacologic evidence-based guidelines is that they list broad categories (eg, yoga or acupuncture) and lack implementation details. How to safely and equitably incorporate integrative approaches into conventional cancer care will be addressed. This ASCO Educational Book article aims to be both evidence-informed and practical, with attention to unique considerations for people with GI cancers.

Evaluating the Impact of a Novel Program to Address Acute Food Insecurity Among Cancer Patients

INTRODUCTION

Acute food insecurity (FI) significantly impacts cancer patients' health, exacerbating physical and psychological burdens. While current interventions address chronic FI, acute cases remain undermanaged. Legacy of Hope, a Philadelphia-based non-profit, addresses this gap through its Emergency Patient Support Network (EPSN), offering free bi-weekly groceries to patients facing acute FI.

MATERIALS AND METHODS

The pilot study evaluated EPSN's impact utilizing the Legacy of Hope Acute Food Insecurity (LOHAFI) survey, which was performed at baseline and two weeks post-intervention. The survey combines the Functional Assessment of Cancer Therapy-General (FACT-G7) and questions on food and financial security. Mean scores and frequencies were calculated.

RESULTS

Fifty patients (n = 50) completed the LOHAFI survey. The mean age was 55.1 years; 70% were female; 33 (66%) identified as Black. Two weeks after receiving groceries, patients reported a decrease in nausea (pre: 1.34; post: 1.18) and anxiety related to their cancer (pre: 2.49; post: 2.41) and an increase in the availability (pre: 1.70; post: 1.84) and consumption (pre: 2.26; post: 2.30) of healthy food. However, patient overall quality of life did not improve (pre: 13.14; post: 12.76).

CONCLUSIONS

Legacy of Hope's EPSN shows potential in alleviating acute FI among cancer patients, although larger studies are needed to fully assess its impact.

Food security among black breast cancer survivors in Maryland: insights from an online pilot study

PURPOSE

Food security, and reliable access to nutritious food, is essential for maintaining health yet remains elusive for many, including U.S. patients with breast cancer (BC). Research specifically focusing on public health consequences of food insecurity in BC survivors is limited. We addressed this gap by exploring the relationship between food security and various sociodemographic, clinical, and cancer-related factors among Black BC survivors in Maryland.

METHODS

The parent study engaged Black female BC survivors in Maryland through digital campaigns and referrals, achieving 100 completed surveys. Food security was assessed through an online follow-up survey with the six-item short form from U.S. Department of Agriculture (USDA), leading to a binary classification for analysis from raw scores. Statistical analysis involved descriptive analysis and Chi-square tests to explore the relationship between food security status, various BC risk factors, and follow-up survey response status.

RESULTS

Of the 31 participants who participated in the follow-up survey, 11 (35.5%) were categorized as having low food security. We observed significant associations between food security status and both income (< $40,000; chi-square p = 0.004) and education levels (high school/GED; chi-square p = 0.004). In comparing respondents to non-respondents, significant differences in employment (p = 0.031) and health insurance status (p = 0.006) were observed.

CONCLUSION

Our descriptive findings demonstrate the importance of further studies evaluating food security screenings in Black BC survivors to enable targeted interventions aiming to improve overall health outcomes and equity in cancer survivorship care.

Randomized pilot trial of an unconditional cash transfer intervention to address food insecurity in oncology

Screening for food insecurity and other social determinants of health is being integrated into oncology practice. We performed a pilot randomized trial to investigate whether an unconditional cash transfer (UCT) could be used to address food insecurity among female breast and gynecological cancer survivors. Food-insecure cancer survivors completed a baseline survey and were randomly assigned to receive $100/month for 3 months (UCT) or usual care (UC). Participants (n = 14) completed a follow-up survey after 3 months, and we compared changes in health-related quality of life, indicators of food insecurity, diet quality, and whether a participant had to forgo, delay, or make changes to medical care because of cost. The UCT was associated with higher physical health scores, fewer indicators of food insecurity, better diet quality, and a lower likelihood of forgoing medical care than those who received UC. Our results suggest that UCTs can improve outcomes for food-insecure cancer survivors.

Social Risk Factor Domains and Preventive Care Services in US Adults

Importance

Growing evidence suggests that social determinants of health are associated with low uptake of preventive care services.

Objective

To examine the independent associations of social risk factor domains with preventive care services among US adults.

Design, Setting, and Participants

This cross-sectional study used National Health Interview Survey data on 82 432 unweighted individuals (239 055 950 weighted) from 2016 to 2018. Subpopulations were created for each of the primary outcomes: routine mammography (women aged 40-74 years), Papanicolaou test (women aged 21-65 years), colonoscopy (adults aged 45-75 years), influenza vaccine (adults aged ≥18 years), and pneumococcal vaccine (adults aged ≥65 years). Statistical analysis was performed from July to December 2023.

Exposures

Six social risk domains (economic instability, lack of community, education deficit, food insecurity, social isolation, and lack of access to care) and a count of domains.

Main Outcomes and Measures

Logistic regression models were used to examine the independent association between each primary outcome (mammography, Papanicolaou test, colonoscopy, influenza vaccine, and pneumococcal vaccine) and social risk factor domains, while controlling for covariates (age, sex, race and ethnicity, health insurance, and comorbidities).

Results

A total of 82 432 unweighted US individuals (239 055 950 weighted individuals) were analyzed. A total of 54.3% were younger than 50 years, and 51.7% were female. All 5 screening outcomes were associated with educational deficit (mammography: odds ratio [OR], 0.73 [95% CI, 0.67-0.80]; Papanicolaou test: OR, 0.78 [95% CI, 0.72-0.85]; influenza vaccine: OR, 0.71 [95% CI, 0.67-0.74]; pneumococcal vaccine: OR, 0.68 [95% CI, 0.63-0.75]; colonoscopy: OR, 0.82 [95% CI, 0.77-0.87]) and a lack of access to care (mammography: OR, 0.32 [95% CI, 0.27-0.38]; Papanicolaou test: OR, 0.49 [95% CI, 0.44-0.54]; influenza vaccine: OR, 0.44 [95% CI, 0.41-0.47]; pneumococcal vaccine: OR, 0.30 [95% CI, 0.25-0.38]; colonoscopy: OR, 0.35 [95% CI, 0.30-0.41]). Fully adjusted models showed that every unit increase in social risk count was significantly associated with decreased odds of receiving a mammography (OR, 0.74 [95% CI, 0.71-0.77]), Papanicolaou test (OR, 0.84 [95% CI, 0.81-0.87]), influenza vaccine (OR, 0.81 [95% CI, 0.80-0.83]), pneumococcal vaccine (OR, 0.80 [95% CI, 0.77-0.83]), and colonoscopy (OR, 0.88 [95% CI, 0.86-0.90]).

Conclusions and Relevance

This cross-sectional study of US adults suggests that social risk factor domains were associated with decreased odds of receiving preventive services; this association was cumulative. There is a need to address social risk factors to optimize receipt of recommended preventive services.

Dietary patterns among U.S. food insecure cancer survivors and the risk of mortality: NHANES 1999-2018

PURPOSE

Food insecurity-the lack of unabated access to nutritious foods-is a consequence many cancer survivors face. Food insecurity is associated with adverse health outcomes and lower diet quality in the general public. The goal of this analysis was to extract major and prevailing dietary patterns among food insecure cancer survivors from observed 24-h recall data and evaluate their relationship to survival after a cancer diagnosis.

METHODS

We implemented two dietary patterns analysis approaches: penalized logistic regression and principal components analysis. Using nationally representative data from the National Health and Nutrition Examination Survey (NHANES) study, we extracted three dietary patterns. Additionally, we evaluated the HEI-2015 for comparison. Cox proportional hazards models assessed the relationship between the diet quality indices and survival after a cancer diagnosis.

RESULTS

There were 981 deaths from all causes and 343 cancer-related deaths. After multivariable adjustment, we found higher risks of all-cause mortality associated with higher adherence to Pattern #1 (HR 1.25; 95% CI 1.09-1.43) and Pattern #2 (HR 1.15; 95% CI 1.01-1.31) among cancer survivors.

CONCLUSION

Among all cancer survivors, higher adherence to major and prevailing dietary patterns from the U.S. food insecure cancer survivor population may lead to worse survival outcomes.

Age at diagnosis and social risks among Black cancer survivors: Results from the Detroit Research on Cancer Survivors cohort

BACKGROUND

Social risks are common among cancer survivors who have the fewest financial resources; however, little is known about how prevalence differs by age at diagnosis, despite younger survivors' relatively low incomes and wealth.

METHODS

The authors used data from 3703 participants in the Detroit Research on Cancer Survivors (ROCS) cohort of Black cancer survivors. Participants self-reported several forms of social risks, including food insecurity, housing instability, utility shut-offs, not getting care because of cost or lack of transportation, and feeling unsafe in their home neighborhood. Modified Poisson models were used to estimate prevalence ratios and 95% confidence intervals (CIs) of social risks by age at diagnosis, controlling for demographic, socioeconomic, and cancer-related factors.

RESULTS

Overall, 35% of participants reported at least one social risk, and 17% reported two or more risks. Social risk prevalence was highest among young adults aged 20-39 years (47%) followed by those aged 40-54 years (43%), 55-64 years (38%), and 65 years and older (24%; p for trend < .001). Compared with survivors who were aged 65 years and older at diagnosis, adjusted prevalence ratios for any social risk were 1.75 (95% CI, 1.42-2.16) for survivors aged 20-39 years, 1.76 (95% CI, 1.52-2.03) for survivors aged 40-54 years, and 1.41 (95% CI, 1.23-1.60) for survivors aged 55-64 years at diagnosis. Similar associations were observed for individual social risks and experiencing two or more risks.

CONCLUSIONS

In this population of Black cancer survivors, social risks were inversely associated with age at diagnosis. Diagnosis in young adulthood and middle age should be considered a risk factor for social risks and should be prioritized in work to reduce the financial effects of cancer on financially vulnerable cancer survivors.

Evaluation of a Conference on Cancer-Related Financial and Legal Issues: A Potential Resource to Counter Financial Toxicity

This study describes the conception, development, and growth of the Triage Cancer Conference hosted by Triage Cancer, a national nonprofit organization providing free legal and financial education to the cancer community. We conducted a retrospective analysis of post-conference participant surveys. Descriptive statistics were calculated for participant demographics, and acceptability, feasibility, and appropriateness were evaluated. From 2016-2021, 1239 participants attended the conference and completed post-conference surveys. Participants included social workers (33%), nurses (30%), and cancer patients/survivors (21%), with representation from over 48 states. Among those who reported race, 16% were Black, and 7% were Hispanic. For acceptability, more than 90% of participants felt that the conference content, instructors, and format were suitable and useful. For feasibility, more than 90% of participants felt that the material was useful, with 93-96% reporting that they were likely to share the information and 98% reporting that they would attend another triage cancer event. Appropriateness was also high, with >80-90% reporting that the sessions met the pre-defined objectives. Triage Cancer fills an important gap in mitigating financial toxicity, and formal evaluation of these programs allows us to build evidence of the role and impact of these existing resources. Future research should focus on adding validated patient-reported outcomes, longer-term follow-up, and ensuring inclusion and evaluation of outcome metrics among vulnerable populations.

Association of food insecurity with overall and disease-specific mortality among cancer survivors in the US

PURPOSE

To investigate the association of food insecurity with overall and disease-specific mortality among US cancer survivors.

METHODS

Data from the National Health and Nutrition Examination Survey (NHANES 1999-2018) were used to examine the impact of food insecurity on mortality risks among cancer survivors in the US. Study participants aged ≥ 20 years who had a history of cancer and completed the Adult Food Security Survey Module were included. Mortality data [all-cause, cancer, and cardiovascular (CVD) specific] through December 31, 2019 were obtained through linkage to the National Death Index. Using multivariable Cox proportional hazard regression, hazard ratios of mortality based on food security status were estimated.

RESULTS

Among 5032 cancer survivors (mean age 62.5 years; 58.0% women; 86.2% non-Hispanic White), 596 (8.8%) reported food insecurity. Overall, 1913 deaths occurred (609 cancer deaths and 420 CVD deaths) during the median follow-up of 6.8 years. After adjusting for age, food insecurity was associated with a higher risk of overall (HR = 1.93; 95% CI = 1.56-2.39), CVD-specific (HR = 1.95; 95% CI = 1.24-3.05), and cancer-specific (HR = 1.70; 95% CI = 1.20-2.42) mortality (P < 0.001). However, after adjusting for socioeconomic characteristics and health-related factors (physical activity, diet quality measured by healthy eating index), the association between food insecurity and overall mortality was no longer statistically significant.

CONCLUSIONS

Food insecurity was associated with a greater risk of overall mortality among cancer survivors. Further studies are needed to confirm these findings and evaluate whether the observed association represents a causal phenomenon and, if so, whether the effect is modifiable with food assistance programs.

Integrating Social Care into Healthcare: A Review on Applying the Social Determinants of Health in Clinical Settings

Despite the substantial health and economic burdens posed by the social determinants of health (SDH), these have yet to be efficiently, sufficiently, and sustainably addressed in clinical settings-medical offices, hospitals, and healthcare systems. Our study contextualized SDH application strategies in U.S. clinical settings by exploring the reasons for integration and identifying target patients/conditions, barriers, and recommendations for clinical translation. The foremost reason for integrating SDH in clinical settings was to identify unmet social needs and link patients to community resources, particularly for vulnerable and complex care populations. This was mainly carried out through SDH screening during patient intake to collect individual-level SDH data within the context of chronic medical, mental health, or behavioral conditions. Challenges and opportunities for integration occurred at the educational, practice, and administrative/institutional levels. Gaps remain in incorporating SDH in patient workflows and EHRs for making clinical decisions and predicting health outcomes. Current strategies are largely directed at moderating individual-level social needs versus addressing community-level root causes of health inequities. Obtaining policy, funding, administrative and staff support for integration, applying a systems approach through interprofessional/intersectoral partnerships, and delivering SDH-centered medical school curricula and training are vital in helping individuals and communities achieve their best possible health.

Impact of Food Insecurity on Outcomes Following Resection of Hepatopancreaticobiliary Cancer

INTRODUCTION

Food insecurity (FI) may predispose individuals to suboptimal nutrition, leading to chronic disease and poor health outcomes. We sought to assess the impact of county-level FI on postoperative outcomes among patients undergoing resection of hepatopancreaticobiliary (HPB) cancer.

METHODS

Patients who were diagnosed with HPB cancer between 2010 and 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Data on annual county-level FI were obtained from the Feeding America: Mapping the Meal Gap report and were categorized into tertiles. Textbook outcome was defined as no extended length of stay, perioperative complications, 90-day readmission, and 90-day mortality. Multiple logistic regression and Cox regression models were used to assess outcomes and survival relative to FI.

RESULTS

Among 49,882 patients (hepatocellular: n = 11,937, 23.9%; intrahepatic cholangiocarcinoma: n = 2111, 4.2%; extrahepatic cholangiocarcinoma: n = 4047, 8.1%; gallbladder: n = 2853, 5.7%; pancreatic: n = 28,934, 58.0%), 6702 (13.4%) patients underwent a surgical resection. Median age was 75 years (interquartile range 69-82), and most patients were male (n = 25,767, 51.7%) and self-identified as White (n = 36,381, 72.9%). Overall, 5291 (10.6%) and 39,664 (79.5%) individuals resided in low or moderate FI counties, respectively, while 4927 (9.8%) patients resided in high FI counties. Achievement of textbook outcome (TO) was 56.3% (n = 6702). After adjusting for competing risk factors, patients residing in high FI counties had lower odds to achieve a TO versus individuals living in low FI counties (odds ratio 0.69, 95% confidence interval [CI] 0.54-0.88, p = 0.003). In addition, patients residing in moderate and high FI counties had a greater risk of mortality at 1- (referent, low, moderate: hazard ratio [HR] 1.09, 95% CI 1.05-1.14; high: HR 1.14, 95% CI 1.08-1.21), 3- (referent, low, moderate: HR 1.09, 95% CI 1.05-1.14; high: HR 1.14, 95% CI 1.08-1.21), and 5- (referent, low, moderate: HR 1.05, 95% CI 1.01-1.09; high: HR 1.07, 95% CI 1.02-1.13) years versus individuals from low FI counties.

CONCLUSIONS

FI was associated with adverse perioperative outcomes and long-term survival following resection of an HPB malignancy. Interventions directed towards mitigating nutritional inequities are needed to improve outcomes among vulnerable HPB populations.

Racial Disparity in Anthracycline-induced Cardiotoxicity in Breast Cancer Patients

Breast cancer has become the most common cancer in the US and worldwide. While advances in early detection and treatment have resulted in a 40% reduction in breast cancer mortality, this reduction has not been achieved uniformly among racial groups. A large percentage of non-metastatic breast cancer mortality is related to the cardiovascular effects of breast cancer therapies. These effects appear to be more prevalent among patients from historically marginalized racial/ethnic backgrounds, such as African American and Hispanic individuals. Anthracyclines, particularly doxorubicin and daunorubicin, are the first-line treatments for breast cancer patients. However, their use is limited by their dose-dependent and cumulative cardiotoxicity, manifested by cardiomyopathy, ischemic heart disease, arrhythmias, hypertension, thromboembolic disorders, and heart failure. Cardiotoxicity risk factors, such as genetic predisposition and preexisting obesity, diabetes, hypertension, and heart diseases, are more prevalent in racial/ethnic minorities and undoubtedly contribute to the risk. Yet, beyond these risk factors, racial/ethnic minorities also face unique challenges that contribute to disparities in the emerging field of cardio-oncology, including socioeconomic factors, food insecurity, and the inability to access healthcare providers, among others. The current review will address genetic, clinical, and social determinants that potentially contribute to this disparity.

Association of unmet basic resource needs with frailty and quality of life among older adults with cancer-Results from the CARE registry

BACKGROUND

Basic resource needs related to transportation, housing, food, and medications are important social determinants of health and modifiable indicators of poverty, but their role in modifying the risk of frailty and health-related quality of life (HRQoL) remains unknown. The goal of our study was to examine the prevalence of unmet basic needs and their association with frailty and HRQoL in a cohort of older adults with cancer.

METHODS

The CARE registry prospectively enrolls older adults (≥60 years) with cancer. Assessments of transportation, housing, and material hardship were added to the CARE tool in 8/2020. The 44-item CARE Frailty Index was used to define frailty, and subdomains of physical and mental HRQoL were assessed using the PROMIS® 10-global. Multivariable analysis examined the association between unmet needs with frailty and HRQoL subdomains, adjusting for covariates.

RESULTS

The cohort included 494 participants. Median age of 69 years, 63.6% were male and 20.2% were Non-Hispanic (NH) Black. Unmet basic needs were reported in 17.8% (transportation 11.5%, housing 2.8%, and material hardship 7.5%). Those with unmet needs were more often NH Black (33.0% vs. 17.8%, p = 0.006) and less educated (

CONCLUSIONS

Unmet basic needs represent a novel exposure that is independently associated with frailty and low HRQoL and warrants the development of targeted interventions.

Food security status and breast cancer screening among women in the United States: Evidence from the Health and Retirement Study and Health Care and Nutrition Study

PURPOSE

To assess the impact of food insecurity on biennial breast cancer screenings (i.e., mammography or breast X-ray) among older women in the United States (US).

METHODS

Data from the 2014 and 2016 waves of the Health and Retirement Study and the 2013 Health Care and Nutrition Study were used. The analyses were limited to a nationally representative sample of 2,861 women between 50 and 74 years of age, residing in the US. We employed a propensity score weighting method to balance observed confounders between food-secure and food-insecure women and fit a binary logistic regression to investigate population-level estimates for the association between food security and breast cancer screening.

RESULTS

Food insecurity was significantly associated with failure to obtain a mammogram or breast X-ray within the past two years. Food-insecure women had 54% lower odds of reporting breast cancer screening in the past 2 years (adjusted OR = 0.46; 95% CI 0.30-0.70, p-value < 0.001) as compared to food-secure women. Additional factors associated with a higher likelihood of receiving breast cancer screenings included greater educational attainment, higher household income, regular access to health care/advice, not smoking, and not being physically disabled or experiencing depressive symptoms.

CONCLUSION

Results demonstrate a socioeconomic gradient existing in regard to the utilization of regular breast cancer screenings among women. Those who tend to have lower education, lower income, and lack of reliable healthcare access are more likely to be food insecure. Thus, more likely to face the financial, logistical, or environmental barriers in obtaining screening services that accompany food insecurity.

Food Insecurity and Nutritional Challenges in Adolescent and Young Adult Cancer Survivors in the U.S.A.: A Narrative Review and Call to Action

Advancements in cancer treatments over the past several decades have led to improved cancer survival in adolescents and young adults (AYAs, ages 15–39 years). However, AYA cancer survivors are at an increased risk for “late effects”, including cardiovascular, pulmonary and bone diseases as well as fatigue, infertility and secondary cancers. The treatments for cancer may also alter taste, lead to nutritional deficiencies and increase financial burdens that, when taken together, may increase the risk of food and nutrition security in AYA cancer survivors. Furthermore, although AYAs are often merged together in cancer survivorship studies, adolescents and young adults have distinct developmental, psychosocial and pathophysiological differences that may modify their risk of nutritional challenges. In this narrative review and “Call to Action”, rationale is provided for why there is a need to better understand nutritional challenges and food insecurity in AYA cancer survivors as a special population. Then, recommendations for next steps to advance knowledge and policy in this field are provided. In particular, integrating screening for food and nutrition insecurity and enhancing awareness of existing resources (e.g., the Supplemental Nutrition Assistance Program, SNAP) might help AYA cancer survivors combat nutritional deficiencies and reduce late effects while improving their overall survival and quality of life.

Prevalence of household food insecurity in the marginal area of Birjand, Iran

Introduction

The right to food is a human right. Food insecurity refers to the inability to prepare proper and healthy food. Food insecurity is associated with adverse outcomes among households. To determine the prevalence of food insecurity, its level, and the factors affecting it among households covered by health centers in marginalized areas of Birjand city.

Methods

This descriptive-analytical cross-sectional study was performed on 396 households aged 20-60 years covered by health centers in the marginal areas of Birjand in 2019. We used a 9-item Household Food Insecurity Access Scale (HFIAS) questionnaire. Chi-square, Fisher, and logistic regression analyses were performed using SPSS 22 software at a significance level of less than 0.05.

Results

The mean age of the subjects was 34.04 ± 9.41 years. In total, 48% of the subjects had a level of food insecurity, of which 7.6% had severe, 12.6% moderate, and 27.5% mild insecurity. The prevalence of food insecurity in families with low members and higher levels of education is significantly lower (p &lt; 001). Backward Logistic regression showed that illiteracy (OR: 8.26) and primary education (OR: 2.65), rental housing status (OR: 1.69), lower-income levels being covered by support organizations (OR: 3.13), employed members between 3-4 and more than five (OR: 2.73 and 2.93, respectively), and low weight (OR: 2.55) were associated with food insecurity. The prevalence of food insecurity in this study was high.

Conclusion

The high prevalence of insecurity in studied households is an alarm for the authorities, which can be due to poverty and the low level of nutritional literacy of households' heads and mothers. Helping to improve the quality of life of families and food insecurity of households by improving physical and economic access, increasing literacy and nutritional culture, and reducing the burden of non-communicable diseases related to nutrition is a suggested solution.

Prevalence of Food Insecurity Among Cancer Survivors in the United States: A Scoping Review

BACKGROUND

Medical financial hardship is an increasingly common consequence of cancer treatment and can lead to food insecurity. However, food security status is not routinely assessed in the health care setting, and the prevalence of food insecurity among cancer survivors is unknown.

OBJECTIVE

This scoping review aimed to identify the prevalence of food insecurity among cancer survivors in the United States before the COVID-19 pandemic.

METHODS

Five databases (PubMed, Scopus, CINAHL [Cumulative Index to Nursing and Allied Health Literature], Web of Science, and ProQuest Dissertations and Theses) were systematically searched for articles that reported on food security status among US patients receiving active cancer treatment or longer-term cancer survivors and were published between January 2015 and December 2020.

RESULTS

Among the 15 articles meeting the inclusion criteria, overall food insecurity prevalence ranged from 4.0% among women presenting to a gynecologic oncology clinic to 83.6% among patients at Federally Qualified Health Centers. Excluding studies focused specifically on Federally Qualified Health Center patients, prevalence of food insecurity ranged from 4.0% to 26.2%, which overlaps the food insecurity prevalence in the general US population during the same time period (range, 10.5% to 14.9%). Women were more likely than men to report being food insecure, and the prevalence of food insecurity was higher among Hispanic and Black patients compared with non-Hispanic White patients.

CONCLUSIONS

Given significant heterogeneity in study populations and sample sizes, it was not possible to estimate an overall food insecurity prevalence among cancer survivors in the United States. Routine surveillance of food security status and other social determinants of health is needed to better detect and address these issues.

Damaged Masculinity: How Honor Endorsement Can Influence Prostate Cancer Screening Decision-Making and Prostate Cancer Mortality Rates

Prior research has established factors that contribute to the likelihood that men seek out prostate cancer screenings. The current study addresses how endorsing the ideology found in cultures of honor may serve as a barrier to prostate cancer screenings. Two studies were conducted which analyzed the impact of stigma on men's decisions to seek out prostate cancer screenings (Study 1) as well as how prostate cancer deaths may be higher in the culture of honor regions due to men's reticence to seek out screenings (Study 2). Results suggest that older, honor-endorsing men are less likely to have ever sought out a prostate cancer screening due to screening stigma and that an honor-oriented region (southern and western United States) displays higher rates of prostate cancer death than a non-honor-oriented region (northern United States). These findings suggest that honor may be a cultural framework to consider when practitioners address patients' screening-related concerns.

Food Insecurity Among People With Cancer: Nutritional Needs as an Essential Component of Care

A cancer diagnosis can upend work and family life, leading patients to reallocate resources away from essentials such as food. Estimates of the percentage of people navigating a cancer diagnosis and food insecurity range between 17% and 55% of the cancer patient population. The complexity of addressing food insecurity among those diagnosed with cancer during different phases of treatment is multifactorial and often requires an extensive network of support throughout each phase. This commentary explores the issue of food insecurity in the context of cancer care, explores current mitigation efforts, and offers a call to action to create a path for food insecurity mitigation in the context of cancer. Three programs that address food insecurity among those with cancer at various stages of care are highlighted, drawing attention to current impact and actionable recommendations to make programs like these scalable and sustainable. Recommendations are grounded in the National Academies of Sciences, Engineering, and Medicine social care framework through 5 essential domain areas: awareness, adjustment, assistance, alignment, and advocacy. This commentary seeks to highlight opportunities for the optimization of cancer care and reframe food access as an essential part of treatment and long-term care plans.

Empirical Dietary Patterns Associated with Food Insecurity in U.S. Cancer Survivors: NHANES 1999-2018

(1) Background: Food insecurity (FI) is a public health and sociodemographic phenomenon that besets many cancer survivors in the United States. FI in cancer survivors may arise as a consequence of financial toxicity stemming from treatment costs, physical impairment, labor force egress, or a combination of those factors. To our knowledge, an understanding of the dietary intake practices of this population has not been delineated but is imperative for addressing the needs of this vulnerable population; (2) Methods: Using data from NHANES, 1999-2018, we characterized major dietary patterns in the food insecure cancer survivor population using: i. penalized logistic regression (logit) and ii. principal components analysis (PCA). We validated these patterns by examining the association of those patterns with food insecurity in the cancer population; (3) Results: Four dietary patterns were extracted with penalized logit and two with PCA. In the pattern validation phase, we found several patterns exhibited strong associations with FI. The FI, SNAP, and Household Size patterns (all extracted with penalized logit) harbored the strongest associations and there was evidence of stronger associations in those moderately removed from a cancer diagnosis (≥2 and <6 years since diagnosis); (4) Conclusions: FI may play an influential role on the dietary intake patterns of cancer survivors in the U.S. The results highlight the relevance of FI screening and monitoring for cancer survivors.

A Scoping Review of Food Insecurity and Related Factors among Cancer Survivors

Despite growing awareness of the financial burden that a cancer diagnosis places on a household, there is limited understanding of the risk for food insecurity among this population. The current study reviewed literature focusing on the relationship between food insecurity, cancer, and related factors among cancer survivors and their caregivers. In total, 49 articles (across 45 studies) were reviewed and spanned topic areas: patient navigation/social worker role, caregiver role, psychosocial impacts, and food insecurity/financial toxicity. Patient navigation yielded positive impacts including perceptions of better quality of care and improved health related quality of life. Caregivers served multiple roles: managing medications, emotional support, and medical advocacy. Subsequently, caregivers experience financial burden with loss of employment and work productivity. Negative psychosocial impacts experienced by cancer survivors included: cognitive impairment, financial constraints, and lack of coping skills. Financial strain experienced by cancer survivors was reported to influence ratings of physical/mental health and symptom burden. These results highlight that fields of food insecurity, obesity, and cancer control have typically grappled with these issues in isolation and have not robustly studied these factors in conjunction. There is an urgent need for well-designed studies with appropriate methods to establish key determinants of food insecurity among cancer survivors with multidisciplinary collaborators.

Examining the Association of Food Insecurity and Being Up-to-Date for Breast and Colorectal Cancer Screenings

BACKGROUND

Food insecurity (FI) has been associated with poor access to health care. It is unclear whether this association is beyond that predicted by income, education, and health insurance. FI may serve as a target for intervention given the many programs designed to ameliorate FI. We examined the association of FI with being up-to-date to colorectal cancer and breast cancer screening guidelines.

METHODS

Nine NCI-designated cancer centers surveyed adults in their catchment areas using demographic items and a two-item FI questionnaire. For the colorectal cancer screening sample (n = 4,816), adults ages 50-75 years who reported having a stool test in the past year or a colonoscopy in the past 10 years were considered up-to-date. For the breast cancer screening sample (n = 2,449), female participants ages 50-74 years who reported having a mammogram in the past 2 years were up-to-date. We used logistic regression to examine the association between colorectal cancer or breast cancer screening status and FI, adjusting for race/ethnicity, income, education, health insurance, and other sociodemographic covariates.

RESULTS

The prevalence of FI was 18.2% and 21.6% among colorectal cancer and breast cancer screening participants, respectively. For screenings, 25.6% of colorectal cancer and 34.1% of breast cancer participants were not up-to-date. In two separate adjusted models, FI was significantly associated with lower odds of being up-to-date with colorectal cancer screening [OR, 0.7; 95% confidence interval (CI), 0.5-0.99)] and breast cancer screening (OR, 0.6; 95% CI, 0.4-0.96).

CONCLUSIONS

FI was inversely associated with being up-to-date for colorectal cancer and breast cancer screening.

IMPACT

Future studies should combine FI and cancer screening interventions to improve screening rates.

An embedded multiple case study: using CFIR to map clinical food security screening constructs for the development of primary care practice guidelines

BACKGROUND

Food insecurity (FI), the limited access to healthy food to live an active and healthy life, is a social determinant of health linked to poor dietary health and difficulty with disease management in the United States (U.S.). Healthcare experts support the adoption of validated screening tools within primary care practice to identify and connect FI patients to healthy and affordable food resources. Yet, a lack of standard practices limits uptake. The purpose of this study was to understand program processes and outcomes of primary care focused FI screening initiatives that may guide wide-scale program implementation.

METHODS

This was an embedded multiple case study of two primary care-focused initiatives implemented in two diverse health systems in Chicago and Suburban Cook County that routinely screened patients for FI and referred them to onsite food assistance programs. The Consolidated Framework for Implementation Research and an iterative process were used to collect/analyze qualitative data through semi-structured interviews with N = 19 healthcare staff. Intended program activities, outcomes, actors, implementation barriers/facilitators and overarching implementation themes were identified as a part of a cross-case analysis.

RESULTS

Programs outcomes included: the number of patients screened, identified as FI and that participated in the onsite food assistance program. Study participants reported limited internal resources as implementation barriers for program activities. The implementation climate that leveraged the strength of community collaborations and aligned internal, implementation climate were critical facilitators that contributed to the flexibility of program activities that were tailored to fill gaps in resources and meet patient and clinician needs.

CONCLUSION

Highly adaptable programs and the healthcare context enhanced implementation feasibility across settings. These characteristics can support program uptake in other settings, but should be used with caution to preserve program fidelity. A foundational model for the development and testing of standard clinical practice was the product of this study.

The Balance Between Food and Medical Care: Experiences of Food Insecurity Among Cancer Survivors and Informal Caregivers

Defined as an inability to acquire enough food because of insufficient money or other resources, the prevalence of food insecurity is markedly higher among cancer survivors than the general population. The objective of this qualitative study was to understand and characterize the experience of food insecurity from the perspective of cancer survivors' and their informal caregivers using qualitative interviews. Barriers to healthy eating, behaviors and strategies in times of food shortage, and unmet educational needs shaped the experience of food insecurity. These experiences and insights for addressing food insecurity in oncology practice have broad implications for future interventions.

Black-White racial disparities in health care utilization and self-reported health among cancer survivors: The role of food insecurity

BACKGROUND

Non-Hispanic Blacks continue to have worse cancer outcomes than non-Hispanic Whites. Suboptimal health care utilization and poor self-reported health among non-Hispanic Blacks contribute to these disparities. The relationship between race, food security status (FSS), and health care utilization or self-reported health among cancer survivors is not clear. This study aims to fill this gap in the science.

METHODS

The 2011-2018 National Health Interview Survey data were used. Bivariate and multivariable logistic regression analyses were used to examine the relationship between race (non-Hispanic Whites or non-Hispanic Blacks), FSS (high, marginal, low, or very low), health care utilization, and self-reported health among cancer survivors. Analyzed health care utilization measures included cost-related medication underuse (CRMU), cost-related delayed care, cost-related forgone care, seeing/talking to a medical specialist, seeing/talking to a general doctor, and overnight hospital stay.

RESULTS

A higher proportion of Blacks reported very low food security in comparison with Whites (10.58% vs 4.24%; P ≤ .0001). Blacks were significantly less likely to report a medical specialist visit and more likely to report fair/poor health in the past 12 months even after adjustments for FSS. There was a dose-response relationship between FSS and CRMU, cost-related delayed care, cost-related forgone care, overnight hospital stay, and self-reported health status for both Whites and Blacks.

CONCLUSIONS

Significant disparities in health care utilization and self-reported health across race and FSS persist among cancer survivors. Interventions that target food insecurity have the potential to reduce suboptimal health care utilization and self-reported health among cancer survivors.

Oncology registered dietitian nutritionists' knowledge, attitudes and practices related to food insecurity among cancer patients: a qualitative study

BACKGROUND

Understanding the knowledge, attitudes and practices pertaining to food insecurity among oncology Registered Dietitian Nutritionists (RDNs) is critical to ensuring that cancer survivors have adequate nutrition-a fundamental component of successful treatment and recovery.

OBJECTIVE

To qualitatively assess Oncology RDN's knowledge, attitudes and practices regarding the food access needs of their patients using a qualitative semantic approach to thematic analysis.

DESIGN

The qualitative cross-sectional study was conducted from September 2018 to January 2019.

PARTICIPANTS/SETTING

Forty-one oncology RDNs working with cancer survivors in various clinical settings across the U.S participated.

MAIN OUTCOME MEASURES

Participants completed a semi-structured, in-depth interview via telephone, lasting an average of 49 minutes.

STATISTICAL ANALYSES PERFORMED

Two coders (primary and secondary) trained in qualitative thematic data analysis methods used a semantic approach to thematic analysis to analyze transcripts. A qualitative and mixed methods online coding program, Dedoose, was used to organize and analyze the data.

RESULTS

Participants defined FI as a lack of access to nutritious foods and a lack of resources to purchase nutritious foods. RDNs stated they believe FI is a serious problem in the U.S., has a greater impact on cancer survivors than healthy individuals and they have specific concerns about FI among their own patients. Despite their concerns, most expressed that they do not use a validated tool to identify FI, nor were they aware that any exists. Only a small proportion of the RDNs stated that they regularly ask patients about their food access needs.

CONCLUSIONS

While Oncology RDNs have heard of FI, they do not routinely assess patients' food security status with a validated tool, nor do they consistently ask patients directly about their food access needs. These findings suggest there is a need for developing education and training opportunities for oncology RDNs in order to enhance their ability to screen for and address FI with their patients.

Is There a Relationship between County-Level Food Insecurity Rates and Breast Cancer Stage at Diagnosis?

The relationship between county food insecurity (FI) rate and breast cancer stage at diagnosis is not clear. Using 2010-2016 Surveillance Epidemiology and End Results (SEER) and Feeding America data we analyzed the association between county FI rate in quartiles (low, medium, high, very high) and breast cancer stage at diagnosis among adult females (≥18 years). We also analyzed the effect of insurance status and county poverty level on this relationship, and whether this relationship varies among non-elderly (<65 years) and elderly (≥ 65 years) individuals. Bivariate and multivariable multilevel logistic regression were used for analyses. Bivariate analysis showed increased likelihood of late-stage breast cancer with increasing county FI rate. This relationship persisted after adjusting for insurance status but was no longer significant after adjusting for county-level poverty rate. There was a statistically significant association between counties with very high food insecurity rates and late-stage breast cancer diagnosis (OR = 1.07; 95% CI = 1.00, 1.14) among the elderly population. Very high county food insecurity rate was associated with late-stage breast cancer among elderly women. Population-level interventions focused on counties with very high food insecurity rates could reduce disparities in stage at breast cancer diagnosis among elderly women.

Food Insecurity Is an Independent Risk Factor for Depressive Symptoms in Survivors of Digestive Cancers

BACKGROUND

Colorectal and other digestive cancer survivors are at increased risk of depression, which can negatively affect health outcomes. Food insecurity (FI), the lack of consistent access to enough food, can also contribute to these health complications. The objective of this study was to determine the relationship between FI and depressive symptoms within this population.

METHODS

We conducted a cross-sectional analysis of data from the 2007-2016 National Health and Nutrition Examination Survey. We included all adults (≥20 years) with a self-reported history of a digestive cancer (including colorectal, esophageal, stomach, liver, and pancreas cancer). Our primary exposure was household FI, and our outcome of interest was depressive symptoms, as measured by the validated 9-item Patient Health Questionnaire. We used multivariable ordinal logistic regression to test the association between FI and depressive symptoms, controlling for demographic and clinical covariates.

RESULTS

We included 229 adult digestive cancer survivors (weighted N = 1,510,579). The majority of the study sample was female and non-Hispanic White with mean of 11.0 years since cancer diagnosis; 14.3% reported FI. In multivariable models controlling for demographic and clinical covariates, we found that food insecure digestive cancer survivors had significantly higher odds of depressive symptoms than food secure digestive cancer survivors (OR: 3.25; 95% confidence interval: 1.24-8.55; P = 0.02).

CONCLUSIONS

Among a nationally representative sample of colorectal cancer and other digestive cancer survivors, FI was associated with increased odds of depressive symptoms.

IMPACT

This study adds further evidence to the negative impact FI may have on survivors' physical and mental health.

Immune activation: A link between food insecurity and chronic disease in people living with HIV

Persistent immune activation is a hallmark of HIV infection and thought to play a role on chronic diseases in people with HIV (PWH). Food insecurity is disproportionately prevalent in PWH and is associated with adverse health outcomes. We determined whether food insecurity was associated with increased plasma levels of sCD14, sCD27, and sCD163 in 323 antiretroviral -treated PWH from the Miami Adult Studies on HIV (MASH) Cohort. Nearly half (42.7%) of participants were food insecure and 85.5% were virally suppressed (<200 copies/mL). Food insecurity was independently associated with higher levels of sCD14 and sCD27. Very low food security was associated with increased sCD163 levels among those with lower CD4+ cell counts. Food insecurity may promote immune activation in PWH, suggesting a biological link between food insecurity and chronic disease among PWH. Improving financial security and access to high-quality diets could reduce the burden of disease in this highly vulnerable population.

Psychosocial impact of the COVID-19 pandemic on cancer patients, survivors and caregivers

Objective: This study aimed to increase understanding of the effects of the pandemic on cancer patients, survivors and caregivers.Methods: An Internet-based survey was accessed over 2 months by individuals diagnosed with cancer or caregivers (N = 281), with descriptive statistics and chi square analysis used to compare subsets.Results: Most participants reported social isolation (76%) and mental health impact (70%) since the beginning of the COVID19 pandemic; isolation appeared to correlate with mental health impact (p < .00001). Food insecurity and financial hardship correlated significantly with mental health impact; food insecurity also correlated with social isolation.Conclusions: Our findings suggest that mental health during the pandemic in the cancer population may be impacted by social isolation, financial stress, and food insecurity, as well as stress regarding accessing cancer treatments. Awareness by psychosocial healthcare providers of need for resources to support these hardships, as well as framework to identify them, are essential elements of cancer-related care.

A qualitative investigation of lived experiences of long-term health condition management with people who are food insecure

Background

As more people are living with one or more chronic health conditions, supporting patients to become activated, self-managers of their conditions has become a key health policy focus both in the UK and internationally. There is also growing evidence in the UK that those with long term health conditions have an increased risk of being food insecure. While international evidence indicates that food insecurity adversely affects individual’s health condition management capability, little is known about how those so affected manage their condition(s) in this context. An investigation of lived experience of health condition management was undertaken with food insecure people living in north east Scotland. The study aimed to explore the challenges facing food insecure people in terms of, i. their self-care condition management practices, and ii. disclosing and discussing the experience of managing their condition with a health care professional, and iii. Notions of the support they might wish to receive from them.

Methods

Twenty in-depth interviews were conducted with individuals attending a food bank and food pantry in north east Scotland. Interview audio recordings were fully transcribed and thematically analysed.

Results

Individuals reporting multiple physical and mental health conditions, took part in the study. Four main themes were identified i.e.: 1. food practices, trade-offs and compromises, that relate to economic constraints and lack of choice; 2. illness experiences and food as they relate to physical and mental ill-health; 3. (in) visibility of participants’ economic vulnerability within health care consultations; and 4. perceptions and expectations of the health care system.

Conclusions

This study, the first of its kind in the UK, indicated that participants’ health condition management aspirations were undermined by the experience of food insecurity, and that their health care consultations in were, on the whole, devoid of discussions of those challenges. As such, the study indicated practical and ethical implications for health care policy, practice and research associated with the risk of intervention-generated health inequalities that were suggested by this study. Better understanding is needed about the impact of household food insecurity on existing ill health, wellbeing and health care use across the UK.

Food Insecurity and Forgone Medical Care Among Cancer Survivors

PURPOSE

Financial hardship is increasingly understood as a negative consequence of cancer and its treatment. As patients with cancer face financial challenges, they may be forced to make a trade-off between food and medical care. We characterized food insecurity and its relationship to treatment adherence in a population-based sample of cancer survivors.

METHODS

Individuals 21 to 64 years old, diagnosed between 2008 and 2016 with stage I-III breast, colorectal, or prostate cancer were identified from the New Mexico Tumor Registry and invited to complete a survey, recalling their financial experience in the year before and the year after cancer diagnosis. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95%CIs.

RESULTS

Among 394 cancer survivors, 229 (58%) were food secure in both the year before and the year after cancer diagnosis (persistently food secure), 38 (10%) were food secure in the year before and food insecure in the year after diagnosis (newly food insecure), and 101 (26%) were food insecure at both times (persistently food insecure). Newly food-insecure (OR, 2.82; 95% CI, 1.02 to 7.79) and persistently food-insecure (OR, 3.04; 95% CI,1.36 to 6.77) cancer survivors were considerably more likely to forgo, delay, or make changes to prescription medication than persistently food-secure survivors. In addition, compared with persistently food-secure cancer survivors, newly food-insecure (OR, 9.23; 95% CI, 2.90 to 29.3), and persistently food-insecure (OR, 9.93; 95% CI, 3.53 to 27.9) cancer survivors were substantially more likely to forgo, delay, or make changes to treatment other than prescription medication.

CONCLUSION

New and persistent food insecurity are negatively associated with treatment adherence. Efforts to screen for and address food insecurity among individuals undergoing cancer treatment should be investigated as a strategy to reduce socioeconomic disparities in cancer outcomes.
