Abstract
Introduction
While prior research has examined individual health-related social needs (HRSNs) in relation to preventive care, few studies have investigated how cumulative social needs affect cancer screening behaviors. This study examines how individual and combined HRSNs affect breast and cervical cancer screening completion.
Methods
Participants included 1,964 female patients overdue for breast or cervical cancer screening, receiving care at Federally Qualified Health Centers. The dependent variable was the completion of the appropriate screening test within 90 days of SMS text message reminders. Adjusted logistic regression models assessed associations between individual and combined HRSNs and screening completion.
Results
Food insecurity (aOR = 0.54) was the only significant predictor of breast cancer screening completion and was also associated with reduced odds of cervical cancer screening. Housing insecurity (aOR = 0.79), living at or below 100%FPL (aOR = 0.82), and having family history of cancer (aOR = 0.62) were associated with lower odds of cervical cancer screening, while completing an annual wellness visit in the previous year was associated with higher odds of cervical cancer screening (aOR = 1.25). In the combined models, each additional HRSN reduced likelihood of completing breast (OR=0.72) and cervical cancer screening (OR=0.77).
Conclusions
Addressing HRSN is essential for improving screening completion in safety-net populations. Interventions targeting food insecurity and housing instability can support access to preventive cancer care.

Introduction
Cancer is the second leading cause of death in the United States, 1 and the number of new cancer cases is projected to reach 1.96 million by 2030. 2 Among females, breast and cervical cancer remain especially consequential, accounting for 316,950 new cases and 42,170 deaths (breast cancer) and 13,360 new cases and 4320 deaths (cervical cancer) in 2025 only, 1 underscoring their significant public health impact. Although there are national declines in mortality for many cancers, late-stage diagnosis continues to affect women in medically underserved urban and rural communities.
The U.S. Preventive Services Task Force recommends mammography and clinical breast examination as the primary modalities for breast cancer screening, while cervical cancer screening is guided by cytology (Pap smear) and high-risk human papillomavirus (HPV) testing. 3 Prior research has shown that early screening for both types of cancer decreases mortality rates yet screening gaps persists. 4 There is a cascade of consequences when early screening is not completed, including later stage diagnoses, intensive treatment with reduced survival, and greater financial burden – a domino effect that increases disparities and worsens outcomes in vulnerable populations.1,2
Texas trails national averages in both breast and cervical cancer screening. For breast cancer screening, 76.4% of Texas women ages 50–74 reported having a mammogram within the past two years, slightly below the national rate of 78.5%. 5 Cervical cancer screening shows a wider gap: only 46.9% of Texas women ages 25–44 received screening consistent with USPSTF guidelines, compared with a national rate of 51.6%. 6 These lower screening rates underscore persistent access barriers in Texas, where socioeconomic factors have been shown to disproportionately impact cancer screening uptake in underserved populations.7-9
Federally Qualified Health Centers (FQHCs), which provide primary care services to 32.4 million low-income individuals across the U.S, 10 play a critical role in delivering preventive services to populations in medically underserved urban and rural communities that experience elevated poverty and health risks. 11 Many FQHC patients experience unmet health-related social needs (HRSNs), which can impede their ability to engage in routine preventive care, making timely cancer screening especially important within these settings.
HRSNs encompass socioeconomic factors such as food insecurity, housing instability, social isolation, and transportation barriers, 12 each of which has been linked to adverse health outcomes. When these needs are unmet, individuals may encounter barriers that compromise their health and well-being, often resulting in delayed or missed preventive services. 13 Assessing how these HRSNs relate to closing cancer screening gaps is essential to reducing the burden of late-stage cancer diagnoses that arise from inadequate screening participation. Although prior research has examined individual HRSNs in relation to preventive health behaviors,14-18 many patients experience multiple, overlapping needs, and few studies have explored this relationship. For instance, a multi-site study of adults aged 50–75 from nine U.S. cancer centers found that food insecurity was associated with 40% lower odds of being up-to-date with breast cancer screening even after adjusting for socioeconomic factors. 19 Using a nationally representative dataset, Pohl et al. found that transportation insecurity was associated with a 41% lower likelihood of breast cancer screening, while work by Misha et al., found that neighborhood vehicle access and distance to clinics are linked to reduced screening rates. 20 Other studies have used text message reminders successfully to increase screening for breast and cervical cancer.21-25
Despite these significant efforts in addressing social needs, the majority of these studies evaluate HRSNs in isolation, without exploring their combined effects. Highlighting the combination of these HRSNs and their role in cancer screening among women is essential to designing more equitable and integrated approaches to cancer prevention and early screening. 26 This study examines how individual and combined HRSNs—social isolation, food insecurity, housing instability, and transportation challenges—affect breast and cervical cancer screening completion.
Method
Data Source
Secondary data, encompassing 2023-2024 records, were obtained from a large FQHC network comprising 56 clinics across Texas. For the purpose of this study, all records were for females, 25 years and older, who were empaneled at the clinic for the past 12 months, and who were overdue for breast or cervical cancer screening at the time the data were extracted. This study was reviewed and approved by the University of Houston Institutional Review Board (IRB Study #STUDY00004081).
Study Sample
As part of routine primary care, the FQHC administers the Protocol for Responding to and Assessing Patients’ Assets, Risks, and Experiences (PRAPARE) tool to systematically collect information on social determinants of health. 27 This standardized instrument assesses a comprehensive range of factors, including housing stability, food security, transportation access, employment, education, social support, stress, and safety. In addition, PRAPARE captures key demographic and enabling characteristics such as language, income, insurance coverage, and household composition, thereby providing a detailed picture of each patient’s social context to inform care planning and linkage to resources.
A total of 4,116 patients were eligible for this study; however, only about 48% had complete HRSN information, and thus, the analytic sample was limited to 1,964 patients who had complete information. Figure 1 shows the data processing flowchart. Data processing and analysis flowchart
The study population was divided into two subgroups: breast cancer screening group (mammogram; n = 695) and a cervical cancer screening group (HPV/Pap; n = 1,269). We also examined the overlap of patient IDs between the two groups. Approximately 5% (n = 101) of patients were included in both cancer screening test groups.
Measurement
This study is a secondary analysis of data previously collected from patients who received an SMS reminder encouraging cancer screening completion. The SMS quality improvement intervention involved a standardized text-message outreach over a 3-month period to patients empaneled to the clinics for at least 12 months prior to the intervention, and who were overdue for recommended cancer screenings. Because all clinics were part of the same FQHC network, message content was consistent across clinics and included brief reminders, encouragement to schedule screening, and instructions for contacting the clinic for assistance. Patients received at least three reminder messages during the outreach period, spaced at regular intervals. While the core protocol was standardized, clinics implemented the messaging within their existing workflows. Additional details regarding the intervention design and implementation are described in our earlier work. 28
There were two separate dependent variables: a) completion of a mammogram within 90 days of reminder SMS notification, and b) completion of an HPV/Pap smear test within 90 days of reminder SMS notification. The key independent variables were binary indicators of HRSNs, including food insecurity, housing instability, transportation limitation, and social isolation. Additional independent variables captured demographic and enabling characteristics such as age, race and ethnicity, poverty status, education level, and employment status. Additional covariates included whether the patient had an annual well visit in the prior year (No, Yes), whether they reported a family history of cancer (No, Yes), and the presence of comorbidities, including heart disease, diabetes mellitus, or depression. The combined social needs variable was defined as the sum of three binary indicators: transportation challenges, housing instability, and food insecurity, corresponding to material social needs. 29 The combined social needs variable ranges from 0 to 3, with higher scores indicating a greater number of reported material social needs. Social isolation was retained as a separate variable because it reflects a distinct psychosocial domain and may influence outcomes through different mechanisms.
Statistical Analysis
Descriptive statistical analysis was used to summarize the characteristics of the two cancer screening test subgroups. Next, we performed two adjusted multivariate logistic regression analyses for each cancer screening test subgroup to examine a) the relationship between individual social needs and cancer screening completion, and b) the relationship between combined social needs and cancer screening completion. All analyses were conducted using SAS 9.4, with statistical significance set at p < 0.05. Results are reported as adjusted odds ratios (aORs) with corresponding 95% confidence intervals (CIs).

Results of the breast cancer regression models are also shown in Table 1. In the individual social needs breast cancer model, food insecurity emerged as the only statistically significant predictor of breast cancer screening completion (aOR = 0.54; 95%CI: 0.36, 0.82) and was associated with lower odds of breast cancer screening compared to patients without food insecurity. In the combined social needs model, each additional social need was associated with a 28% decrease in the likelihood of completing a mammogram (aOR=0.72; 95%CI: 0.53, 0.94).

Results of the cervical cancer regression models are also shown in Table 2. Those experiencing housing instability had lower odds (aOR = 0.79; 95%CI: 0.63, 0.99) of completing a cervical cancer screening test, compared to female patients who did not report housing issues. Those with family incomes at or below 100% FPL had significantly lower odds (aOR = 0.82; 95%CI: 0.69, 0.97) of completing a cervical cancer screening compared to those with higher income levels. Female participants who had an annual wellness visit in the prior year had higher odds (aOR = 1.25; 95%CI: 1.06, 1.48) of completing a cervical cancer screening test. Conversely, those with a family history of cancer had lower odds (aOR = 0.62; 95%CI: 0.48, 0.81) of completing a cervical cancer screening test. In the combined social needs model, each additional social need was associated with a 23% decrease in the lower likelihood of completing a HPV/Pap screening (aOR=0.77; 95%CI: 0.61, 0.96).
Discussion
In this study examining social factors and cancer screening completion rates within a large FQHC network in Texas, we found that females reporting food insecurity had an almost fifty percent lower odds of completing their breast cancer screening, while those reporting housing insecurity had a twenty percent lower likelihood of completing their cervical cancer screening. The effect of multiple social needs was especially concerning, as each additional need was associated with a 20-30% reduced likelihood of completing the cancer screenings. While other variables including family income, prior annual wellness visits, and family cancer history were associated with cervical cancer screening rates, food insecurity emerged as the single correlate associated with reduced breast cancer screening completion. These findings emphasize that social needs are associated with key healthcare process measures and underscore the importance of sustained investment in interventions that address these social needs.
Our results align with prior findings examining social factors influencing cancer screening rates. 30 Pavlicic et al, using data from the New York State Behavioral Risk Factor Surveillance System (BRFSS) reported a decreased likelihood of being up to date on colorectal cancer screening among individuals with food insecurity. 31 Mendoza and colleagues reported a 40% lower odds of breast cancer screening among individuals who screened positive for food insecurity. 19 Prior research has documented how individuals experiencing food insecurity often have limited access to nutrient-dense foods, relying more on processed/calorie-dense options. Often, those experiencing food insecurity reside in food and medical deserts, and this geographic pattern may hinder access to healthy foods and engagement in preventive care.16,32-39
Additionally, individuals experiencing food insecurity often face broader socioeconomic stressors, which may take precedence over preventive health screenings.14,15 In this context, food insecurity may function as a proxy indicator of acute life stress and resource scarcity, which can limit individuals’ ability to engage in routine, usual care.14,40 Addressing food insecurity may therefore be an important strategy for improving cancer screening uptake in underserved populations.
Prior research supports the observed relationship between housing insecurity and cancer screening. 41 Decker et al, in a matched cohort study, reported that unhoused veterans were less commonly screened for cancer, and gaining housing increased screening rates. 42 Because housing insecurity is often associated with frequent moves, it can interfere directly with scheduling, completing, or following up on recommended cancer screenings. These trends reinforce the need for interventions that address housing-related barriers among medically vulnerable populations.
The significant negative association between family history of cancer and the likelihood of completing a screening deserves particular attention. This relationship has been reported in other studies that included predominantly African American and Hispanic populations. For example, prior work suggests that in some African American and Hispanic communities, discussing or planning for cancer is often considered taboo, as it may be perceived as inviting or “speaking” the disease into existence.43,44 We posit that a “you become what you confess” belief can potentially discourage open conversations about family health history and preventive screening. Given that safety-net populations in this study are predominantly Hispanic and African American, these findings align with cultural narratives that may inadvertently contribute to delayed screening and later-stage diagnoses. Accordingly, there is an urgent need for culturally responsive interventions in these subpopulations, to boost cancer screening completion rates. Recent work provides evidence of CHW involvement in cancer screening, training, education, and prevention in medically underserved populations. 45
Our results support prior work that suggests that having a prior annual wellness visit was strongly associated with increased rates of cervical cancer screening completion. For example, Hamer et al found that having an annual wellness visit was associated with more than a 20-percentage point increase in the mammogram completion within six months. 46 Annual visits serve as opportunities for preventive care, allowing providers to review screening eligibility, update family and medical histories, and place orders for age-appropriate cancer screenings such as mammography, Pap tests, and colorectal cancer tests. By integrating screening reminders and care coordination into these visits, health systems can leverage the annual wellness visits as a low-cost, high-impact strategy to improve population-level cancer screening rates and reduce disparities in preventive care.
Finally, these findings have important implications for access to care in Texas—which has the highest uninsured population in the US (21.6% in 2023)and remains a Medicaid non-Expansion state.47,48 Both uninsurance and Medicaid non-expansion have been closely tied to limited access to routine preventive care.49,50 Additionally, in March 2025, the Centers for Medicare & Medicaid Services (CMS) formally rescinded federal guidance encouraging Medicaid authorities to cover and integrate supports for HRSNs, 51 signaling a shift in policy emphasis that may make it more difficult for states and providers to secure sustainable coverage for programs addressing upstream determinants. Together, high uninsurance rates and diminished federal encouragement for systematized social needs coverage 52 may reduce opportunities for patients experiencing food or housing insecurity to engage in preventive care, even within safety-net clinical settings.
This study is not without limitations. First, the findings are based on data from a large FQHC network located within a single state (Texas), which may limit the generalizability of the results to other regions or healthcare systems. Additionally, we did not formally compare the demographic characteristics of the study sample with those of the broader catchment area served by the network. Therefore, it is unclear whether the study population fully represents the overall population within the service area. The analysis was limited to patients without missing social needs data. Because more than 50% of patients had missing social needs information, those individuals were excluded rather than imputed, which may introduce selection bias. Data are from FQHC clinics; hence, findings may not be fully generalizable to other healthcare environments with different patient demographics. Due to the dynamic nature of social needs, a patient may have one need resolved, but a new need may arise months later that can impact the likelihood of screening. These cyclical changes in social needs are not captured in the secondary data, and hence, unaccounted for in this study. In addition, because clinic-level identifiers were not available, we were unable to account for potential clustering across the 56 clinics within the FQHC network, which may have led to underestimated standard errors. Finally, social needs information are self-reported, and as with all self-reports, there is a likelihood of bias due to factors such as recall inaccuracies, social desirability, or misunderstanding of the questions. Despite these limitations, this study adds to the limited body of work on cancer screening in Texas, where screening rates have long been among the lowest in the country.
Future research should examine whether these findings are consistent across other health systems and geographic settings. Replication studies in larger and more diverse populations will help determine the generalizability of these associations and strengthen the evidence base on the impact of social needs on cancer screening uptake.
Conclusion
Addressing health-related social needs is vital for improving screening completion in safety-net populations. Targeted interventions that address multiple social risks, including food insecurity and housing instability, are particularly important in promoting preventive care screenings.
