Physical Activity Among Adults With Mobility Disability: Insights From 2019 Behavioral Risk Factor Surveillance System

Socioeconomic and medical determinants of state-level subjective cognitive decline in the United States.

It is important to understand the socioeconomic and medical determinants of subjective cognitive decline (SCD) at a population level in the United States. The primary outcomes are state-level rates of SCD and SCD-related functional impairment in adults aged ≥ 45, both measured in the Behavioral Risk Factor Surveillance System from 2016 to 2022. The exposures are state-level rates of poverty, unemployment, homelessness, college education, racial and ethnic minorities, uninsurance, smoking, hypertension, diabetes, and obesity as well as household income and physician density. The strongest state-level associations with rates of SCD were the prevalence of diabetes (rho=0.64), hypertension (rho=0.59), and poverty (rho=0.58; all p<0.001), and with SCD-related functional impairment were prevalence of poverty (rho=0.71), diabetes (rho=0.68), and hypertension (rho=0.53; all p<0.001). This study highlights critical links between SCD and socioeconomic and medical determinants in adults aged ≥ 45 in the United States, including the prevalence of poverty, diabetes, and hypertension. State-level analysis reveals socioeconomic and medical risk factors for subjective cognitive decline (SCD) at a population level. The prevalence of poverty is a critical contributor to the state-level prevalence of SCD. The prevalence of diabetes and hypertension are also strong state-level determinants of SCD. Addressing the burden of cognitive decline at the population level necessitates targeting socioeconomic and medical factors.

S405 Surveillance for E-Cigarette Use and the Risk for Colorectal Cancer - Findings from the National Behavioral Risk Factor Surveillance System United States

Examining the pathways from adverse childhood experiences to substance use

BackgroundAdverse childhood experiences (ACEs) are traumatic events that occur early in life and can have lasting effects on health and well-being. Previous research has linked ACEs to substance use in adulthood, but there is limited research on the underlying mechanisms or pathways of this relationship. This study explores whether depression mediates the relationship between ACEs and current substance use among U.S. adults. MethodsData were obtained from the 2021 Behavioral Risk Factor Surveillance System (n = 30,978). Generalized Structural Equation Modeling was used to examine the links between ACEs, cigarette, e-cigarette, and marijuana use while adjusting for sociodemographic characteristics. ResultsApproximately 71 % of respondents reported experiencing at least one ACE. The findings show that depressive disorders mediate the relationship between ACEs and current substance use among U.S. adults. There was a significant indirect effect of ACEs on current cigarette use (OR = 1.13, 95 % CI [1.10, 1.16]), e-cigarette use (OR = 1.17, 95 % CI [1.12–1.22]), and marijuana use (OR = 1.22, 95 % CI [1.13, 1.33]) through the mediator of depressive disorders. Additionally, the most pronounced effects were found among those aged 18–24 years for cigarette use (OR = 1.32, 95 % CI [1.11, 1.56]), e-cigarette use (OR = 1.22 [1.09, 1.36]), and especially marijuana use (OR = 1.52 [1.18, 1.96]). ConclusionThese findings suggest that depression may be a key pathway from negative experiences during childhood to certain types of substance use in adulthood, particularly among young adults.

Social determinant of health and COVID-19 vaccine uptake among US cancer survivors.

369 Background: According to the National Comprehensive Cancer Network Guidelines, all individuals with cancer survivors should receive COVID vaccination. However, the extent to which social determinants of health (SDoH) influence the uptake of COVID-19 vaccines in this specific population remains an area of exploration. We aim to examine the potential impact of SDoH on COVID-19 vaccine uptake in cancer survivors. Methods: Cancer survivors with known COVID-19 vaccination status and SDoH information including food insecurity, housing insecurity and transportation barriers were extracted from the 2022 Behavioral Risk Factor Surveillance System (BRFSS). We employed chi-square tests to compare baseline demographics and COVID-19 vaccine uptake by SDoH factors. Logistic regression model was used to calculate the association between SDoH factors and COVID-19 vaccine uptake among cancer survivors, after adjusting for potential confounders. All analyses were weighted. The significance level was set at 2-sided p&lt;0.05. Results: A total of 13025 cancer survivors were included (weighted N=4,620,447) with 85.9% reporting having at least 1 dose of COVID-19 vaccine in the past. After adjusting for confounders, we found that cancer survivors experiencing food insecurity (odds ratio [OR]:0.63, 95% confidence interval [CI]: 0.44-0.90), housing insecurity (OR: 0.63; 95%CI: 0.42-0.96), transportation insecurity (OR: 0.51; 95%CI: 0.31-0.81) and any of the above barriers (OR: 0.58; 95%CI: 0.41-0.82) were significantly less likely to have received at least one dose of the COVID-19 vaccine. Conclusions: 15% cancer survivors reported never having received COVID-19 vaccine. Additionally, we found that having food, housing and transportation insecurity is independently associated with decreased COVID-19 vaccine uptake among US cancer survivors. Prior studies have shown that cancer survivors who with COIVD infections had a higher mortality and hospitalization rate than non-cancer population. These findings emphasize the importance of addressing SDoH in public health efforts to ensure equitable access to vaccines, particularly for a population at increased risk.

Heterogeneous Association Between E-Cigarette Use and Diabetes Prevalence Among U.S. Adults

IntroductionE-cigarette use has increased among US adults. While the association between traditional cigarette smoking and the diabetes/prediabetes prevalence is well established, the relationship between e-cigarette use and these conditions remains unclear. This study examines the association between different types of cigarette use (including e-cigarettes alone, combustible cigarettes alone, and dual use) and the prevalence of prediabetes and diabetes among US adults. MethodsWe analyzed 1,285,783 observations from the 2020-2022 Behavioral Risk Factor Surveillance System surveys. Self-reported prediabetes and diabetes diagnoses were outcomes of interest. Propensity score matching with one-to-one nearest-neighbor matching was used to create balanced groups of smokers and non-smokers. Multivariable logistic regressions examined associations between self-reported smoking status and outcomes. We also conducted subgroup analyses to assess potential variations in these associations. Analyses were performed in September-December 2023. ResultsAfter propensity score matching and adjusting for covariates, sole e-cigarette users (adjusted odds ratio [AOR], 1.07; 95% CI, 1.03-1.11) and dual users (AOR, 1.28; 95% CI, 1.23-1.33) had higher odds of prediabetes diagnosis compared with never users. Sole e-cigarette use was not associated with diabetes risk, but dual users showed higher odds for diabetes diagnosis (AOR, 1.09; 95% CI, 1.06-1.11) versus never users. E-cigarette use was associated with varying odds of prediabetes and diabetes across different demographic groups. ConclusionsThis cross-sectional analysis found that e-cigarette use is associated with higher odds of prediabetes, with dual use potentially linked to increased odds of both prediabetes and diabetes. However, due to study limitations, including its cross-sectional design, self-reported data, and unmeasured confounders, these findings should be interpreted cautiously. As causal relationships and temporal sequences cannot be established, large prospective studies are needed to explore the metabolic health implications of emerging tobacco product use.

Diabetes prediction model based on GA-XGBoost and stacking ensemble algorithm.

Diabetes, as an incurable lifelong chronic disease, has profound and far-reaching effects on patients. Given this, early intervention is particularly crucial, as it can not only significantly improve the prognosis of patients but also provide valuable reference information for clinical treatment. This study selected the BRFSS (Behavioral Risk Factor Surveillance System) dataset, which is publicly available on the Kaggle platform, as the research object, aiming to provide a scientific basis for the early diagnosis and treatment of diabetes through advanced machine learning techniques. Firstly, the dataset was balanced using various sampling methods; secondly, a Stacking model based on GA-XGBoost (XGBoost model optimized by genetic algorithm) was constructed for the risk prediction of diabetes; finally, the interpretability of the model was deeply analyzed using Shapley values. The results show: (1) Random oversampling, ADASYN, SMOTE, and SMOTEENN were used for data balance processing, among which SMOTEENN showed better efficiency and effect in dealing with data imbalance. (2) The GA-XGBoost model optimized the hyperparameters of the XGBoost model through a genetic algorithm to improve the model's predictive accuracy. Combined with the better-performing LightGBM model and random forest model, a two-layer Stacking model was constructed. This model not only outperforms single machine learning models in predictive effect but also provides a new idea and method in the field of model integration. (3) Shapley value analysis identified features that have a significant impact on the prediction of diabetes, such as age and body mass index. This analysis not only enhances the transparency of the model but also provides more precise treatment decision support for doctors and patients. In summary, this study has not only improved the accuracy of predicting the risk of diabetes by adopting advanced machine learning techniques and model integration strategies but also provided a powerful tool for the early diagnosis and personalized treatment of diabetes.

Trends in prevalence of adverse childhood experiences by sociodemographic factors in the United States: Behavioral Risk Factor Surveillance System 2009–2022

BackgroundLimited data exists on trends in prevalence of adverse childhood experiences (ACE) at the national level and sociodemographic correlates of having ACEs. This study examined trends in ACE prevalence and sociodemographic correlates in US adults over 14 years using nationally representative data.MethodsData on 447,162 adults from the Behavioral Risk Factor Surveillance System (BRFSS) across four timepoints (2009–2010; 2011–2012; 2019–2020; 2021–2022) was analyzed and weighted for population estimates. The primary outcome was ACEs with 3 groups used (0 vs. 1 + ACEs; <4 vs. 4 + ACEs; 0 vs. 1 vs. 2 vs. 3 vs. 4 + ACEs). Sociodemographic factors included age, sex, race/ethnicity, employment, education, marital status, income and insurance status. Prevalence trends were examined by estimating prevalence of ACE groupings (0/1+; <4/4+; 0,1,2,3,4+) across the four timepoints and trend analysis was performed to determine if the differences over time were statistically significant. Unadjusted and adjusted prevalence ratios were estimated using log-binomial regression models with ACE groupings as the outcome and timepoints as the primary independent variable with sociodemographic factors as covariates.ResultsAcross the four time points, prevalence of ACEs was higher across groupings of ACEs by time. For ACEs 1+, prevalence was 62.2% (2009–2010); 62.2% (2011–2012); 64.5% (2019–2020); and 67.2% (2021–2022). For ACEs 4+, prevalence was 17.4% (2009–2010); 18.1% (2011–2012); 20.4% (2019–2020); and 22.6% (2021–2022). Prevalence of ACE 1 + was higher for older adults, Non-Hispanic Black adults, Non-Hispanic Other adults, and those with higher education. Prevalence of 4 + ACEs was higher for females, and lower for those with higher education and those with higher annual incomes.ConclusionThis study shows an increased prevalence of having ACEs over a 14-year period and identified independent sociodemographic correlates of having ACEs in a nationally representative study. Targeted interventions are needed to reduce burden of ACEs using population-based approaches.

Adverse Childhood Events Significantly Impact Depression and Mental Distress in Adults with a History of Cancer.

Objectives: Adverse childhood experiences (ACEs) are linked to a heightened risk of depression. We explored the relationship between ACEs and both depression and mental distress among cancer survivors. Methods: This was a cross-sectional analysis using the 2022 Behavioral Risk Factor Surveillance System database of cancer survivors aged ≥18 (n = 14,132). The primary outcome was self-reported history of depression, and the secondary outcome was mental distress. The exposure variable was the number of ACEs, classified as 0, 1-2, and ≥3. Weighted multivariable logistic regression models assessed the association between the number of ACEs and depression and mental distress while adjusting for covariates. Results: Approximately 22% of respondents reported experiencing ≥3 ACEs. The prevalence of depression was 21.8%, and mental distress was 15.4%. Compared with cancer survivors who had experienced 0 ACEs, those who had experienced ≥3 (aOR = 3.94; 95% CI, 3.04-5.10) or 1-2 (aOR = 1.85; 95% CI, 1.47-2.32) ACEs had a higher likelihood of reporting depression. Compared with cancer survivors who had experienced 0 ACEs, those who had experienced ≥3 (aOR = 0.67; 95% CI, 0.48-0.93) had a lower likelihood of reporting mental distress. Conclusions: This study highlights the impact of ACEs on depression in adulthood among cancer survivors.

Sex differences in state level prevalence of alcohol use among Black women and men in the United States

ABSTRACT Background To investigate differences in alcohol use among Black men and women across U.S. states, using data from the Behavioral Risk Factor Surveillance System. Methods Measured any alcohol use, heavy drinking (i.e., 8+/15+ drinks for women/men in a 7-day period), and binge drinking (i.e., 4+/5+ drinks in one session). Weighted prevalence estimates were age-standardized to the 2000 US population. Results Binge drinking among Black men in Midwestern states was high, ranging from 40% in Minnesota to 45.8% in Iowa. Black women in Southern states had 6–10% points higher prevalence of heavy drinking than Black men. Conclusions Drinking prevalence in Southern states was higher than expected, especially among Black women.

Disparities in Healthcare Access for Adults with Self-Reported Vision Difficulty - Behavioral Risk Factor Surveillance System 2019–2021

ABSTRACT Purpose Identifying barriers experienced by individuals with vision difficulty (VD) in accessing healthcare is crucial to inform public health policies to provide equitable healthcare. We examined the association between VD with healthcare access measures in the United States (U.S.). Methods We used data on 1,258,919 participants surveyed from the 2019, 2020, and 2021 cycles of the Behavioral Risk Factor Surveillance System (BRFSS), a national telephone-based survey of U.S. adults ≥ 18 years. The following outcome of healthcare access were examined: no healthcare coverage, no healthcare provider, >1 year since last checkup, inability to afford healthcare. VD was self-reported blindness/serious difficulty seeing even when wearing glasses. Survey-weighted, multivariable logistic regression models were used to examine the relationship between VD and the outcomes of interest, adjusting for confounders. Results Of the 1,258,919 participants surveyed from 2019 to 2021, 5.1% reported having VD. Adjusted models showed that adults with VD had greater odds of having no healthcare coverage (OR = 1.14, 95% CI = 1.04-1.24), no provider (OR = 1.12; 95% CI = 1.05-1.20), a health checkup > 1 year ago (OR = 1.12; 95% CI = 1.04-1.21), and of being unable to afford care (OR = 1.62, 95% CI = 1.52-1.73). Conclusion Adults reporting VD faced more barriers accessing healthcare. These disparities could be explained by a differential distribution of social determinants of health, lack of accessibility of medical facilities and communication barriers. Policies aimed at strengthening provisions around accessibility of healthcare facilities might result in increased access to healthcare for this population.

Abstract A119: Disparities in mammography screening adherence throughout phases of the COVID-19 Pandemic: Results from the 2018, 2020, and 2022 Behavioral Risk Factor Surveillance System

Abstract Background Early detection of breast cancer through mammography screening reduces mortality risk. Disruptions during the COVID-19 pandemic in the United States worsened disparities in mammography use, and it is unclear if the impact persisted after the rollout of COVID-19 vaccine in 2021. We aim to describe disparities among minority and underserved women in breast cancer screening before and during the initial phase of the COVID-19 pandemic and assess any changes in screening patterns following the rollout of COVID-19 vaccines in the United States. Methods We used Behavioral Risk Factor Surveillance System (BRFSS) data for years before (2018), during (2020), and after (2022) the COVID-19 vaccine rollout in the United States. We estimated the proportion of women aged 50–74 years who were non-adherent to the United States Preventive Services Taskforce screening guidelines (no mammography in the past two years) by select sociodemographic and behavioral factors. Weighted frequencies, Chi-square tests with Rao-Scott correction, and log-binomial regression models with a Poisson family were used to estimate prevalence ratios (PR) for non-adherence by selected factors to identify sub-populations more likely to be non-adherent. Results A total of 116,756, 102,778, and 110,456 women were included in the analytic samples from 2018, 2020, and 2022, respectively. The prevalence of non-adherence to breast cancer screening guidelines was 21.1%, 20.6%, and 21.6%, in 2018, 2020, and 2022, respectively. Comparing 2018 to 2022, the proportion of non-adherent women significantly increased among those who did not graduate high school (26.7% vs 34.7%), those without health insurance (45.3% vs 61.9%), and women with incomes below $15,000 (28.1% vs 35.1%). Insurance status had the largest impact on screening adherence, with uninsured women more than twice as likely to be non-adherent compared to insured women both before (PR = 2.15, 95% CI: 1.94, 2.38) and after the COVID-19 vaccine rollout (2.24, 95% CI: 2.05, 2.45). Prevalence ratios of nonadherence significantly increased between 2018 and 2020, then returned back to pre-pandemic levels in 2022 among those living in non-metropolitan versus metropolitan areas, never married versus married, self-employed versus employed, and those reporting poor versus excellent health. Hispanics were more likely than non-Hispanics to be non-adherent in 2020 and 2022, but no difference was seen in 2018. Conclusions Persistent disparities in breast cancer screening adherence among eligible women in the United States were observed throughout the phases of the COVID-19 pandemic. Although overall adherence remained stable, certain subgroups, such as those with lower education, no health insurance, Hispanic, rural residence, and lower income, experienced worsening adherence. Health insurance status was the most significant factor associated with non-adherence, highlighting the need for targeted interventions among those who are uninsured.

Abstract A155: Perceived interpersonal racism in healthcare settings and cancer screening

Abstract Introduction: Black and Hispanic people frequently report that perceptions of their race or ethnicity underlie racist and discriminatory experiences in many settings. In the healthcare field, these interpersonal racist experiences can severely impact the decision to receive care and the general health of the patient. Previous studies assessing the role of perceived racial discrimination in the healthcare setting and cancer screenings struggled with low sample sizes that precluded meaningful conclusions. Also, a methodological issue not considered in prior studies is the large degree of uncertainty reported by racialized groups in their assessment of perceived racism and its relevance to the measurement of this construct. In response to these data limitations and newly available nationally representative Behavioral Risk Factor Surveillance System data, we assessed the relationship of perceived racial discrimination in the healthcare setting associated with timely cancer screening across racial/ethnic groups. Methods: Data was collected from the 2022 Behavioral Risk Factor Surveillance System, which is a nationally representative state level population-based household survey with 28 states and the District of Columbia administering the optional modules assessing perceived racial discrimination. Perceived racism in healthcare was measured with the question: “Within the past 12 months when seeking health care, do you feel your experiences were worse than, the same as, or better than for people of other races?”. The outcomes were USPSTF recommendation concordant up-to-date colorectal, cervical, and breast cancer screening. Survey weighted logistic regression models adjusted for age, sex, education, and state estimated prevalence differences stratified by race/ethnicity. Results: Colorectal, cervical, and breast cancer screening were lower in White persons who reported worse (aPD vs. "better": -11.6%, -15.8%, -19.3%) and uncertain (don’t know) experiences of racial discrimination (aPD vs. "better": -7.4%, -4.1%, -5.0%). Among Black people, colorectal and cervical screening were only lower in those reporting uncertain experiences (aPD vs. "better": -10.8% and -12.0%). Among Hispanic persons, breast cancer screening prevalence was lowest in those who reported uncertain and worse racial discrimination (aPD vs. “better”: -12.4% and -15.9%). Conclusions: In this large generalizable sample, perceived racial discrimination in the healthcare setting was associated with cancer screening for both White and Black persons, but in different ways. Worse interpersonal racism in the healthcare setting was associated with lower cancer screening in White persons; but being uncertain relative to other race groups was largely associated with worse cancer screening among Black persons. Uncertainty in self-reported, racist experiences must be considered in institutional efforts to measure and address racism in healthcare settings.

Abstract A117: Cervical cancer screening rates among older Hispanic women living in Texas: results using the BRFSS 2018, 2020, and 2022 survey data

Abstract Background: Despite cancer risk increasing with age, older women are less likely to be up-to- date with cervical cancer screening (CCS). CCS is recommended up-to 65 years, absent history of abnormal results. CCS rates are significantly lower among Hispanic women, despite higher cervical cancer incidence and mortality rates compared to non-Hispanic white women. In Texas, women older than 50 years have lower odds of timely pap testing. We examined CCS rates among older Hispanic women in Texas using data from the Behavioral Risk Factor Surveillance System. Methods: Our sample included 5,291 self-identified Hispanic women, ages 50-64. Outcome: receipt of pap smear within the last 3 years following the U.S. Preventive Services Task Force guidelines at the time each survey was conducted (years: 2018, 2020 and 2022). Descriptive analysis and chi-square tests were used to examine the proportion of women who reported receiving CCS within the recommended timeframe. Results: Only 63.75% (mean age = 56.4) reported getting a pap smear. Significant decreases were found among women who had a pap smear from 87.03% in 2018, 71.95% in 2020, and 43.24% in 2022 (p=0.00). Additional analyses will be conducted to test relationships with sociodemographic and healthcare variables. Conclusion: Older Hispanic women in Texas represented in this dataset are far from the 2030 Healthy People goal of 79% CCS. Decreases in CCS rates are possibly due to the COVID-19 pandemic impact on healthcare access. As the US population ages, research is needed to identify the potential systemic barriers this group is confronting to access preventive cancer care.

Abstract A135: Social disparities in breast cancer screening: Up-to-date screening versus overscreening

Abstract Objective: The United States Preventative Services Task Force breast cancer (BC) screening guidelines in 2022 recommended biennial mammography for women aged 50-74 and cited insufficient evidence to assess mammography’s benefits vs. harms in women aged ≥75. Other guidelines recommend screening cessation for women with &amp;lt;10 years of life expectancy. We examined how racial/ethnic, socioeconomic and geographic patterns observed in up-to-date screening (UTDS) for age-eligible women differ from women aged out of these guidelines or those with limited life expectancy (i.e. overscreening). Methods: We used nationally representative data from the 2022 Behavioral Risk Factor Surveillance System for women aged 50+. Women screened in the past 1-2 years were considered UTDS in age group 50-74 and ‘overscreened’ if 75+ or with a high mortality risk of any age (≥8 score using modified Lee mortality index). We used multivariable logistic regressions to examine UTDS and overscreening in relation to self-identified race/ethnicity, metropolitan status, having a personal health care provider, highest education level, and marital status, stratified by age group and mortality risk. Results: 19.2% of 99601 women aged 50-74 did not have UTDS, while 73.7% of 34545 women 75+ and 60.2% of 22225 women with limited life expectancy continued to receive screening (overscreened). Among those aged 50-74, compared to non-Hispanic (NH) White, NH American Indian/Alaskan Native women (OR=0.60, 95% CI=0.45–0.82) and NH women of unknown race (OR=0.61, 95% CI=0.45–0.82) were less likely to have UTDS while NH Black (OR=1.81, 95% CI=1.60–2.03) and Hispanic (OR=1.24, 95% CI=1.05–1.46) women were more likely to have UTDS. Lower socioeconomic resources were consistently associated with lower likelihood of UTDS (e.g. not having vs. having a personal health care provider (OR=0.22, 95% CI=0.19–0.26) or high school or less education vs. higher than high school (OR=0.73, 95% CI=0.67–0.79)). In ages 75+, compared to NH White, NH Black women were more likely to be overscreened (OR=1.32, 95% CI=1.06–1.65), and NH women of unknown race were less likely to be overscreened (OR=0.49, 95% CI=0.29–0.83). Low socioeconomic indicators were also associated with lower likelihood of overscreening (e.g. not having vs. having a personal health care provider (OR=0.48, 95% CI=0.36–0.63) or high school or less education vs. higher than high school (OR=0.76, 95% CI=0.67–0.86)). Among women with a higher mortality risk, NH Black women (OR=2.05, 95% CI=1.64–2.56) and Hispanic women (OR=1.61, 95% CI=1.09– 2.38) were more likely to be overscreened than NH White women. Conclusion: The findings reveal racial/ethnic, socioeconomic and geographic disparities in UTDS. NH Black and Hispanic women, who are more likely to have UTDS, may be at risk of overscreening as they age or if they have limited life expectancy. These patterns in UTDS and overscreening are critical considerations for implementing equitable BC screening guidelines and optimizing the benefits while minimizing the harms of screening in diverse populations.

Abstract PR002: County-level food insecurity and hepatocellular carcinoma risk: A cross-sectional analysis

Abstract Background: Hepatocellular carcinoma (HCC), the most common type of primary liver cancer, is the sixth most common cancer and third leading cause of cancer deaths worldwide. Hepatitis B and/or C virus, alcohol use, and obesity are main drivers of HCC incidence and prognosis, with risk higher among Black and Hispanic individuals and those with lower socioeconomic status. HCC etiology recently shifted from viral to non-viral-related causes, with up to 40% of HCC cases unexplained by known risk factors. Food insecurity (FI) is associated with several known and emerging HCC risk factors, including poor diet quality, obesity, and diabetes. However, there is limited data on whether FI is in fact a social determinant of HCC risk. In this study, we conducted a county-level cross-sectional analysis to examine whether FI is associated with HCC risk in the United States. Methods: We used the Surveillance Epidemiology and End Results 22 database to obtain county-level counts of HCC cases from 2018-2021 stratified by age (20-64, ≥65 years), sex (female, male), and race and ethnicity (non-Hispanic White, non- Hispanic Black, non-Hispanic Asian or Pacific Islander, non-Hispanic American Indian or Alaska Native, and Hispanic). We obtained county-level FI rates for the years 2018-2021 from Feeding America’s Map the Meal Gap and calculated the average rate over these years. FI rates were calculated using imputation methods that consider state- and county-level sociodemographic variables associated with FI. We obtained additional county-level variables from the Behavior Risk Factor Surveillance System for the years 2018-2021. We used multi- level Poisson regression models with robust standard errors to estimate the association between FI and HCC risk. Models specified county population size as the offset term, and random effects for states and counties. We examined models adjusted for age, sex, race, and ethnicity (Model 1), and further adjusted for county-level binge drinking, smoking, obesity, and diabetes rates (Model 2). We tested multiplicative effect modification by individual-level factors. Results: We included 38,986 cases of HCC diagnosed in 1,085 counties. The mean county-level FI rate was 12.9% (standard deviation (SD)=3.6%). Overall, a 1-SD increase in FI was associated with a 9% increase in HCC risk in Model 1 (incidence rate ratio (IRR)=1.09, 95% CI=1.04-1.15) and a 5% increase in risk in Model 2 (IRR=1.05, 95% CI=1.02-1.09). When stratified by race and ethnicity, FI was only associated with HCC risk in non-Hispanic Whites in Model 2 (IRR=1.07, 95% CI=1.03-1.11; interaction p-value=.05). When stratified by age, FI was only associated with HCC risk in the &amp;lt;65 years group (IRR=1.13, 95% CI=1.08-1.18; interaction p-value &amp;lt;.001). The association did not differ by sex. Conclusion: This study provides some of the first data linking FI to increased HCC risk, in particular early onset HCC. If confirmed in other studies, these findings support the need for interventions that screen for, prevent, and address FI in populations at increased risk for HCC. Citation Format: Rebecca D.

Abstract A146: Racial/ethnic differences in the relationship between human papillomavirus vaccination status and up-to-date Papanicolaou tests

Abstract Background: Human papillomavirus (HPV) vaccination and routine Papanicolaou (Pap) testing can prevent morbidity and mortality associated with cervical cancer (CC). Research suggests women who have initiated and completed the HPV vaccine are more likely to have an up-to-date Pap test than women who are unvaccinated against HPV. Limited research has focused on whether the association between HPV vaccination and Pap testing varies based on the number of HPV vaccine doses received across racial/ethnic groups. Methods: We conducted a cross-sectional analysis of 2018 – 2022 Behavioral Risk Factor Surveillance System data to investigate the relationship between HPV vaccination status and having an up-to-date Pap test by race/ethnicity. Based on the Advisory Committee on Immunization Practices’ (ACIP) guidelines, women who received 0 doses of the HPV vaccine were unvaccinated, women who received 1 or 2 doses initiated the vaccine series, and women who received 3 doses completed the HPV vaccine series. Based on the United States Preventive Services Task Force guidelines, women were considered to have an up-to-date Pap test if they reported having one within the past 3 years. We used weighted multivariable logistic regression models to examine the association. Results: Most women (n = 14,615) were unvaccinated (82.9%) and had an up-to- date Pap test (75.5%). Non-Hispanic White (NHW) women had the highest rate of HPV vaccine series completion (11.8%), followed by non-Hispanic Other (NHO) women (11.2%), non- Hispanic Black (NHB) women (8.6%), and Hispanic women (8.3%). NHW women also had the highest rate of up-to-date Pap test (78.8%). NHB women had the second highest rate (77.6%), followed by Hispanic women (67.8%), and NHO women (66.4%). In adjusted analyses, NHO women were 34% less likely to have an up-to-date Pap test than NHW women (OR, 0.66; 95% CI: 0.51-0.86). Compared to unvaccinated women, those who completed and initiated the HPV vaccine series were more likely to have an up-to-date Pap test (initiated: OR: 1.40, 95% CI: 1.04-1.87; completed: OR:1.77, 95% CI: 1.35-2.34). NHB and NHO women who initiated the HPV vaccine series were more likely to have an up-to-date Pap test (NHB: OR: 3.37, 95% CI: 1.65-6.85; NHO: OR: 3.21, 95% CI: 1.73-5.95). NHW women who completed the HPV vaccine series were more likely to have an up-to-date Pap test (OR: 2.19, 95% CI: 1.55-3.08). Conclusion: NHB and NHO women who initiated the HPV vaccine series were three times as likely to have an up-to-date Pap test; NHW women who have completed the HPV vaccine series were twice as likely to receive an up-to-date Pap test. Women who do not receive Pap tests or the HPV vaccine miss important CC prevention opportunities. Thus, relevant stakeholders should aim to improve HPV vaccination rates; doing so could potentially enhance Pap test adherence simultaneously. This may be especially important for NHB and NHO women as they have lower rates of Pap test adherence and HPV vaccine series completion.

Abstract A015: Small area-estimation for low mammography screening: Geographic and racial disparities in mammography screening, 2015 – 2022

Abstract Background: Mammography screening is associated with at least a 20% reduction in breast cancer mortality. However, there are racial/ethnic differences in breast cancer mortality. For example, non-Hispanic Black (NHB) women are significantly more likely to die of breast cancer than non-Hispanic White (NHW) women. Few studies have reported small-area estimates for mammography screening among the entire US population; differences by race were either not examined or resulted in mixed findings. The American Cancer Society (ACS) and the United States Preventive Services Taskforce (USPSTF) recommend regular mammography screening from age 40 through 74 years. The current study aims to identify areas of up-to-date mammography screening and to elucidate whether mammography screening varied by geographical location, race, or ethnicity. Methods: Mammography screening within the past 12 months was retrieved from the 2015-2022 Behavioral Risk Factor Surveillance System data. The study population consisted of adult women aged 40 and older residing within the United States. 2020 US census tract population estimates were used to generate gender (all women), race/ethnicity (NHB, NHW, non-Hispanic Asian, and Hispanic/Latina), income, and age group weights for each US census tract. Synthetic estimates of mammography screening uptake at the census tract were conducted using our novel PARIS model (Probability of mammography screening within the past year, given age, race/ethnicity, income, and state) using a multilevel logistic regression model. Regional differences in mammography screening by US Census Bureau regions and divisions were examined. Results: Up-to-date mammography among all women in the sample was 55.98% (SD = 2.07; F (3, 72429) = 2886.81, p &amp;lt; .0001). Mammography screening examined by race indicated the greatest screening rates among non-Hispanic Black women (M = 60.78, SD = 3.11) and least among Asian women (M = 48.68, SD = 3.15). Among four US Census Bureau regions, the West region had the lowest rates of mammography screening among women (M = 54.74, SD = 1.85) while the South region had the highest rates (M = 56.55, SD = 2.18; F(3, 72429) = 2886.81, p &amp;lt; .0001). After further parsing geographical units, the West Pacific region, among the 9 US Census Bureau divisions, had the lowest mammography screening (M = 54.53, SD = 1.81) while the East South Central division had the highest rates of mammography screening (M = 56.94, SD = 2.10; F(8, 72429) = 1360.60, p &amp;lt; .0001).Conclusion: Using novel geospatial methods, the current study elucidated significant differences in mammography screening by race and place. These results suggest that Black women and women living in the South have higher up-to-date mammography screening compared to other women. Thus, the existing inequities in breast cancer outcomes may be explained by differences in the cancer care continuum (delays in follow-up care, treatment, and breast cancer survival). Further examination of the interplay between screening uptake, late-stage diagnosis, and death is needed. Citation Format: Sydney P. Howard, Justin X.

Abstract B060: Bridging gaps in cancer care: Evaluating community health worker presence in Alabama on rates of cancer screening and lifestyle-related outcomes

Abstract Purpose Alabama has the 7th highest cancer mortality in the US. The University of Alabama at Birmingham O’Neal Comprehensive Cancer Center—the only NCI-designated comprehensive cancer center in the state—endeavors to reduce cancer mortality and burden. For 25 years, its Office of Community Outreach and Engagement (OCOE) has applied a community health worker (CHW) outreach and engagement model for cancer awareness, navigation to screening and healthy lifestyle promotion. OCOE hired and trained CHWs to provide services in counties with highest cancer burden. CHW presence fluctuated over time due to grant-funding and other extraneous events. This study evaluates the association of CHW presence with cancer screening and lifestyle-related outcomes. Methods We utilized latest CDC PLACES data (drawn from 2018 and 2020 Behavioral Risk Factor Surveillance System) which provides model-based, population-level age-adjusted prevalence estimates of county-level cancer screening (breast, cervical, colon) and lifestyle outcomes (physical inactivity, obesity, smoking). We evaluated change in rates over time between counties with and without CHW presence using linear mixed effects models. Results Compared to counties without CHW presence, those with CHW presence in 2020 had 0.7% higher mammography rate in 2018 (95% CI: -0.8, 2.3) and 0% difference in mammography rate per year change (95% CI: -0.6, 0.7); counties with CHW presence in both years had 2.8% higher mammography rate (95% CI: 1.1, 4.6) and 0.2% faster increase in mammography rate per year (95% CI: -0.5, 1.0). Counties with CHW presence in both 2018 and 2020 had 1.8% lower rate of colon cancer screening in 2018 (95% CI: -3.6, 0.02) and 1.3% increase in colon cancer screening per year (95% CI: 0.5, 2.1). Counties with CHW presence in 2020 had 1% higher physical inactivity rate in 2018 (95% CI: -2.3, 4.3) and 0.3% faster decrease in physical inactivity rate per year (95% CI: -1.0, 0.4); counties with CHW presence in both years had 3.6% higher physical inactivity rate in 2018 and 0.2% faster decrease in physical inactivity rate per year (95% CI: -0.8, 0.5). Counties with CHW presence in 2020 only had 1.8% higher obesity rate in 2018 (95% CI: -1.7, 5.2) and 0.9% faster decline in obesity rate per year (95% CI: -2.2, 0.4); counties with CHW presence in both years had 5.1% higher obesity rate in 2018 (95% CI: 1.9, 8.3) and 0.3% faster decline in obesity rate per year (95% CI: -1.6, 0.9). There were no statistically significant differences for cervical cancer screening or smoking. Conclusion The OCOE CHW model provided access, education and empowerment for AL residents to obtain cancer screenings and participate in healthy lifestyle behaviors. CHW presence (particularly sustained presence over time) was associated with improved mammography and colon cancer screening, reduced physical inactivity and reduced obesity. Further study of CHW presence and these outcomes during and post COVID-19 is ongoing. Expansion of the CHW model across the entire state is a priority to reduce cancer mortality among Alabamians.

Abstract A126: Cancer screening trends in Louisiana’s sexual gender minority population

Abstract Cancer screenings in Louisiana (LA) have been consistently lower than the national average. Sexual and gender minorities (SGM) are more likely to be non-compliant with cancer screening guidelines and consistently do not meet cancer screening recommendations. This study compares compliance to cervical, breast, and colorectal cancer (CRC) screening guidelines over time between SGM and the non-SGM population in LA. Data were obtained from the LA 2014, 2016, 2018, 2020, and 2022 Behavioral Risk Factor Surveillance System (BRFSS). The sample was divided into gay (including lesbian, gay, bisexual, or other sexual orientation other than straight) and straight. Three primary outcomes of interest were used to measure breast, cervical, and CRC cancer screening adherence based on the U.S. Preventive Services Task Force (USPSTF) screening recommendation at the time of each survey. Descriptive analysis and chi-square tests were conducted using sample weights. CRC had the lowest compliance rate in the entire population and across sexual orientation groups. Twenty-five percent of both populations had never received any CRC screening test. Comparatively, 3.6% of straight and 5.3% of gay populations had never received a mammogram while 6.6% of straight and 13.6% of the population had never received a pap smear. Significant improvements in compliance to breast, cervical, and CRC cancer screenings guidelines was observed among those who identified as straight over the survey years until 2020. Decreases in screening compliance were observed in this population from 2020 to 2022, likely due to the effects of the COVID pandemic. Screening compliance in those who identified as gay showed more variation over time in all three cancers. Screening compliance for CRC and cervical cancer were at its highest in 2016, declined to its lowest point in 2020, but increased in 2022. In 2016, there was a significant decline in breast cancer screening compliance in this population to the lowest ever observed in both groups. The initial increases in colorectal and cervical cancer screening observed from 2014 to 2016 among the gay population may be attributed to significant decreases in uninsured rates following the passage of the Affordable Care Act. Additionally, this population saw increased access to the private insurance market following the Obergefell decision and the Marriage Equality Act of 2015, which extended employer-sponsored coverage to same-sex couples. While breast cancer screenings declined from 2014-2016 in the gay population, there was a sharp increase from 2016 to 2018, which aligns with the 2016 expansion of Medicaid in Louisiana. Despite increases in access to insurance coverage, SGM individuals report being in fair or poor health and having negative experiences with healthcare providers at higher rates than their non-SGM counterparts. More research is needed to understand the healthcare landscape and experiences of SGM Louisianans. This will help to inform targeted interventions to increase screenings and improve cancer outcomes among this population. Citation Format: Bilikisu Elewonibi, Carleigh Baudoin, Ashely Fenton.
