Abstract
METHODS Investigated the association of multiple cardiometabolic comorbidities with total/major cause-specific mortality and evaluate if this association might be modified by race among predominantly low-income Black and White participants. METHODS The Southern Community Cohort Study, prospective cohort study. Participants (40-79 years) recruited predominantly from community health centers across 12 states in southeastern United States. Enrollment began in 2002 and concluded in 2009, follow-up until 2020. Cardiometabolic comorbidities (diabetes, hypertension, myocardial infarction, stroke) ascertained at the baseline survey. Cox proportional hazard models used. RESULTS Study included 76,721 participants; 16,197, 41,944, 5,247, and 4,919 participants with prior diagnosis of diabetes, hypertension, myocardial infarction, and stroke, respectively at baseline. Compared to individuals with no comorbidity, individuals with any single comorbidity experienced a significantly 30 to 90% increased rate of death due to any causes. The increase in mortality was elevated with an increasing number of comorbidities, with HR of 3.81 (95% CI: 3.26-4.46) and a cumulative risk of 62.5% at age 75 years for total mortality for those with four comorbidities. The risk was high for death due to cardiovascular diseases (HR: 6.18, 95% CI: 5.12-7.47). These associations were stronger among Blacks than Whites. Individuals with four comorbidities at age 40 years were estimated to have a 16-year loss in life expectancy compared with those without any comorbidity. CONCLUSION Cardiometabolic comorbidities were associated with increases in all-cause and major cause-specific mortality, particularly Black Americans. This study calls for effective measures to prevent cardiometabolic comorbidities to reduce premature deaths in underserved Americans.

Abstract
BACKGROUND Metformin, utilized to manage hyperglycemia, has been linked to a reduced risk of colorectal cancer (CRC) among individuals with diabetes. However, evidence is lacking for non-Hispanic Black individuals and those with lower socioeconomic status (SES), who face elevated risk for both diabetes and CRC. In this study, we investigated the association between metformin use and incident CRC risk within the Southern Community Cohort Study (SCCS), a racially- and SES-diverse prospective cohort. METHODS Participants reported their diabetes diagnosis and medications, including metformin, upon enrollment (2002-2009) and during follow-up surveys approximately every five years. Incident cases of CRC were identified through state cancer registries and the National Death Index. Proportional hazards models were employed to explore the relationship between metformin use and CRC risk, adjusted for cancer risk factors. RESULTS A total of 25,992 participants with diabetes were included in the analysis, among whom 10,095 were taking metformin. Of these participants, 76% identified as non-Hispanic Black, and 60% reported household incomes <$15,000/year. Metformin use was associated with a significantly lower CRC risk (HR [95% CI]: 0.71 [0.55-0.93]), with consistent results for both colon (0.80 [0.59-1.07]) and rectal cancers (0.49 [0.28-0.86]). The protective association appeared to be stronger among non-Hispanic White individuals (0.51 [0.31-0.85]) compared to non-Hispanic Black participants (0.80 [0.59-1.08], p-interaction =.13). Additionally, a protective association was observed among obese individuals (BMI ≥30 kg/m2, 0.59 [0.43-0.82] but not among non-obese participants (0.99 [0.65-1.51], p-interaction =.05) CONCLUSION: Our findings indicate that metformin use is associated with a reduced risk of CRC in individuals with diabetes, including among those from predominantly low SES backgrounds. These results support previous epidemiological findings, and demonstrate that the protective association for metformin in relation to incident CRC likely generalizes to populations with higher underlying risk.

Abstract
BACKGROUND The feasibility of precision smoking treatment in socioeconomically disadvantaged communities has not been studied. METHODS Participants in the Southern Community Cohort Study who smoked daily were invited to join a pilot randomized controlled trial of three smoking cessation interventions: guideline-based care (GBC), GBC plus nicotine metabolism-informed care (MIC), and GBC plus counseling guided by a polygenic risk score (PRS) for lung cancer. Feasibility was assessed by rates of study enrollment, engagement, and retention, targeting > 70% for each. Using logistic regression, we also assessed whether feasibility varied by age, sex, race, income, education, and attitudes toward precision smoking treatment. RESULTS Of 92 eligible individuals (79.3% Black; 68.2% with household income < $15,000), 67 (72.8%; 95% CI 63.0-80.9%) enrolled and were randomized. Of these, 58 (86.6%; 95% CI 76.4-92.8%) engaged with the intervention, and of these engaged participants, 43 (74.1%; 95% CI 61.6-83.7%) were retained at 6-month follow-up. Conditional on enrollment, older age was associated with lower engagement (OR 0.83, 95% CI 0.73-0.95, p = 0.008). Conditional on engagement, retention was significantly lower in the PRS arm than in the GBC arm (OR 0.18, 95% CI 0.03-1.00, p = 0.050). No other selection effects were observed. CONCLUSIONS Genetically informed precision smoking cessation interventions are feasible in socioeconomically disadvantaged communities, exhibiting high enrollment, engagement, and retention irrespective of race, sex, income, education, or attitudes toward precision smoking treatment. Future smoking cessation interventions in this population should take steps to engage older people and to sustain participation in interventions that include genetic risk counseling.

Abstract
Importance Type 2 diabetes and colorectal cancer (CRC) disproportionately burden indviduals of low socioeconomic status and African American race. Although diabetes is an emerging CRC risk factor, associations between diabetes and CRC in these populations are understudied. Objective To determine if diabetes is associated with CRC risk in a cohort representing understudied populations. Design, Setting, and Participants This cohort study uses data from the prospective Southern Community Cohort Study in the US, which recruited from 2002 to 2009 and completed 3 follow-up surveys by 2018. Of about 85 000 participants, 86% enrolled at community health centers, while 14% were enrolled via mail or telephone from the same 12 recruitment states. Participants with less than 2 years of follow-up, previous cancer diagnosis (excluding nonmelanoma skin cancer) at enrollment, missing enrollment diabetes status, diabetes diagnosis before age 30, and without diabetes at enrollment with no follow-up participation were excluded. Data were analyzed from January to September 2023. Exposures Physician-diagnosed diabetes and age at diabetes diagnosis were self-reported via survey at enrollment and 3 follow-ups. Main Outcomes and Measures Diabetes diagnosis was hypothesized to be positively associated with CRC risk before analysis. Incident CRC was assessed via state cancer registry and National Death Index linkage. Hazard ratios and 95% CIs were obtained via Cox proportional hazard models, using time-varying diabetes exposure. Results Among 54 597 participants, the median (IQR) enrollment age was 51 (46-58) years, 34 786 (64%) were female, 36 170 (66%) were African American, and 28 792 (53%) had income less than $15 000 per year. In total, 289 of 25 992 participants with diabetes developed CRC, vs 197 of 28 605 participants without diabetes. Diabetes was associated with increased CRC risk (hazard ratio [HR], 1.47; 95% CI, 1.21-1.79). Greater associations were observed among participants without colonoscopy screening (HR, 2.07; 95% CI, 1.16-3.67) and with smoking history (HR, 1.62; 95% CI, 1.14-2.31), potentially due to cancer screening differences. Greater associations were also observed for participants with recent diabetes diagnoses (diabetes duration <5 years compared with 5-10 years; HR, 2.55; 95% CI, 1.77-3.67), possibly due to recent screening. Conclusions and Relevance In this study where the majority of participants were African American with low socioeconomic status, diabetes was associated with elevated CRC risk, suggesting that diabetes prevention and control may reduce CRC disparities. The association was attenuated for those who completed colonoscopies, highlighting how adverse effects of diabetes-related metabolic dysregulation may be disrupted by preventative screening.

Abstract
BACKGROUND Obesity may increase colorectal cancer (CRC) risk through mechanisms of increased inflammation. Although BMI is the most used adiposity indicator, it may less accurately measure adiposity in Black populations. Herein, we investigate associations between BMI, low albumin as an inflammation biomarker, and CRC risk in a racially diverse cohort. METHODS Participant data arise from 71,141 participants of the Southern Community Cohort Study, including 724 incident CRC cases. Within the cohort, 69% are Black. Blood serum albumin concentrations, from samples taken at enrollment, were available for 235 cases and 567 controls. Controls matched by age, sex, and race were selected through incidence density sampling. Cox proportional hazards calculated BMI and CRC risk associations (hazard ratios [HRs]; 95% confidence intervals [CIs]. Conditional logistic regression calculated albumin and CRC risk associations (odds ratios [ORs]; 95%CIs). RESULTS Underweight, but not overweight or obese, compared to normal BMI was associated with increased CRC risk (HR:1.75, 95%CI:1.00-3.09). Each standard deviation increase of albumin was associated with decreased CRC risk, particularly for those who self-identified as non-Hispanic Black (OR: 0.56, 95%CI:0.34-0.91), or female (OR:0.54, 95%CI:0.30-0.98), but there was no evidence for interaction by these variables (p-interactions > 0.05). Moreover, albumin concentration was lower in Black than White participants. Mediation analysis suggested that the relation between albumin and CRC was not mediated by BMI. CONCLUSIONS Null associations of overweight/obesity with CRC risk demonstrates limited utility of BMI, especially among Black populations. Low albumin may indicate CRC risk. In Black individuals, albumin may better predict adiposity related risks than BMI.

Abstract
BACKGROUND Observational studies show high prediagnosis 25-hydroxyvitamin D is associated with lower mortality after colorectal cancer diagnosis. Results from clinical trials suggest vitamin D supplementation may improve outcomes among patients with colorectal cancer. Most studies included few Black Americans, who typically have lower 25-hydroxyvitamin D. We evaluated associations between serum 25-hydroxyvitamin D and mortality after colorectal cancer diagnosis among Black American cases. METHODS Data arose from 218 Black Americans from the Southern Community Cohort Study diagnosed with colorectal cancer during follow-up (age 40-79 at enrollment). Prediagnostic 25-hydroxyvitamin D was measured at enrollment and categorized as deficient (<12 ng/mL), insufficient (12-19.9 ng/mL), or sufficient (≥20 ng/mL). Mortality was determined from the National Death Index. Cox proportional hazards were used to estimate HRs and 95% confidence intervals (CI) for associations between 25-hydroxyvitamin D and mortality. RESULTS As a continuous exposure, higher 25-hydroxyvitamin D was associated with overall mortality [HR = 0.79 (0.65-0.96) per-SD increase, Ptrend = 0.02] and colorectal cancer-specific mortality [HR = 0.83 (0.64-1.08), Ptrend = 0.16]. For overall mortality, associations were strongest among females [HR = 0.65 (0.42-0.92)], current smokers [HR = 0.61 (0.38-0.98)], and obese participants [HR = 0.47 (0.29-0.77)]. Compared with those with deficiency, participants with sufficient 25-hydroxyvitamin D had lower overall mortality after multivariable adjustment [HR: 0.61 (0.37-1.01)]. CONCLUSIONS Prediagnosis 25-hydroxyvitamin D is inversely associated with overall and colorectal cancer-specific mortality among Black Americans with colorectal cancer. Correcting vitamin D deficiency may improve survival of these patients, particularly for obese individuals and smokers. IMPACT Our results support including more Black Americans in trials of vitamin D supplementations to improve colorectal cancer outcomes.

Abstract
Black Americans of low socioeconomic status (SES) have higher colorectal cancer incidence than other groups in the United States. However, much of the research that identifies colorectal cancer risk factors is conducted in cohorts of high SES and non-Hispanic White participants. Adult participants of the Southern Community Cohort Study (N = 75,182) were followed for a median of 12.25 years where 742 incident colorectal cancers were identified. The majority of the cohort are non-Hispanic White or Black and have low household income. Cox models were used to estimate HRs for colorectal cancer incidence associated with sociocultural factors, access to and use of healthcare, and healthy lifestyle scores to represent healthy eating, alcohol intake, smoking, and physical activity. The association between Black race and colorectal cancer was consistent and not diminished by accounting for SES, access to healthcare, or healthy lifestyle [HR = 1.34; 95% confidence interval (CI),1.10-1.63]. Colorectal cancer screening was a strong, risk reduction factor for colorectal cancer (HR = 0.65; 95% CI, 0.55-0.78), and among colorectal cancer-screened, Black race was not associated with risk. Participants with high school education were at lower colorectal cancer risk (HR = 0.81; 95% CI, 0.67-0.98). Income and neighborhood-level SES were not strongly associated with colorectal cancer risk. Whereas individual health behaviors were not associated with risk, participants that reported adhering to ≥3 health behaviors had a 19% (95% CI, 1-34) decreased colorectal cancer risk compared with participants that reported ≤1 behaviors. The association was consistent in fully-adjusted models, although HRs were no longer significant. Colorectal cancer screening, education, and a lifestyle that includes healthy behaviors lowers colorectal cancer risk. Racial disparities in colorectal cancer risk may be diminished by colorectal cancer screening. PREVENTION RELEVANCE Colorectal cancer risk may be reduced through screening, higher educational attainment and performing more health behaviors. Importantly, our data show that colorectal cancer screening is an important colorectal cancer prevention strategy to eliminate the racial disparity in colorectal cancer risk.

Abstract
OBJECTIVE To test whether 2 conceptually overlapping constructs, dispositional optimism (generalized positive expectations) and optimistic bias (inaccurately low risk perceptions), may have different implications for smoking treatment engagement. METHOD Predominantly Black, low-income Southern Community Cohort study smokers (n = 880) self-reported dispositional optimism and pessimism (Life Orientation Test-Revised subscales: 0 = neutral, 12 = high optimism/pessimism), comparative lung cancer risk (Low/Average/High), and information to calculate objective lung cancer risk (Low/Med/High). Perceived risk was categorized as accurate (perceived = objective), optimistically-biased (perceived < objective), or pessimistically-biased (perceived > objective). One-way ANOVAs tested associations between dispositional optimism/pessimism and perceived risk accuracy. Multivariable logistic regressions tested independent associations of optimism/pessimism and perceived risk accuracy with cessation motivation (Low/High), confidence (Low/High), and precision treatment attitudes (Favorable/Unfavorable), controlling for sociodemographics and nicotine dependence. RESULTS Mean dispositional optimism/pessimism scores were 8.41 (SD = 2.59) and 5.65 (SD = 3.02), respectively. Perceived lung cancer risk was 38% accurate, 27% optimistically-biased, and 35% pessimistically-biased. Accuracy was unrelated to dispositional optimism (F(2, 641) = 1.23, p = .29), though optimistically-biased (vs. pessimistically-biased) smokers had higher dispositional pessimism (F(2, 628) = 3.17, p = .043). Dispositional optimism was associated with higher confidence (Adjusted odds ratio [AOR] = 1.71, 95% CI [1.42, 2.06], p < .001) and favorable precision treatment attitudes (AOR = 1.66, 95% CI [1.37, 2.01], p < .001). Optimistically-biased (vs. accurate) risk perception was associated with lower motivation (AOR = .64, 95% CI [.42, .98], p = .041) and less favorable precision treatment attitudes (AOR = .59, 95% CI [.38, .94], p = .029). CONCLUSIONS Dispositional optimism and lung cancer risk perception accuracy were unrelated. Dispositional optimism was associated with favorable engagement-related outcomes and optimistically-biased risk perception with unfavorable outcomes, reinforcing the distinctiveness of these constructs and their implications for smoking treatment.

Abstract
Abstract
Introduction: Epidemiologic studies and controlled trials provide evidence that higher 25-hydroxyvitaminD is associated with improved survival in colorectal cancer (CRC), although there are limited data in African Americans (AAs), who are at greater risk for CRC mortality and vitamin D deficiency. Herein, we report associations between vitamin D serum biomarkers collected at cohort entry up to 15 years prior to CRC onset and CRC tumor subtypes defined by high expression of tumor markers (Ki67, p53, and COX2) that represent cellular processes (proliferation, apoptosis, and inflammation) affected by vitamin D. Importantly, higher expression of these markers reflects greater risk for metastasis and CRC-specific mortality.
Methods: Data arise from the Southern Community Cohort Study, a cohort from the southeastern United States where the majority of participants are AA. Incident CRC cases with tumor sample were analyzed (n=104). Expression of cellular Ki67, p53, and COX2 (% positivity) were measured and categorized by literature-defined high vs. low cut-points (20%, 10%, and 20%, respectively). Logistic models adjusted for age, race, and sex were used to measure associations between vitamin D biomarkers: 25-hydroxyvitaminD, vitamin D binding protein (VDBP), and calculated free 25-hydroxyvitaminD (vitamin D not bound by VDBP) and the odds of a more aggressive tumor subtype, defined by higher cellular expression. Associations were assessed in the full sample and the subsample of AAs (n=70).
Results: There were 52 tumors with high Ki67 expression, 37 with high p53, and 50 with high COX2. Fifteen tumors had high expression of all three markers. Cases were 55.8±0.4 (mean±SE) years at enrollment (range 40-79). The median 25-hydroxyvitaminD was lower in cases with high p53 expressing tumors compared to low expression (13.5 vs. 18.0 ng/mL, respectively, p = .03). Median values for other biomarkers were similar by tumor subtype (p > .05). 25-hydroxyvitaminD was not associated with having a tumor with high Ki67 expression (odds ratio (OR) per 1 SD increase [95% CI] = 1.29 [0.85-1.95], p-trend = .23), high p53 expression (0.80 [0.52-1.23], p-trend = .30), or high COX2 expression (1.29 [0.83-2.00], p = .25). We observed null associations for VDBP, and free 25-hydroxyvitaminD with all tumor subtypes. Results were similar in AAs, although higher VDBP was associated with lower odds of high Ki67 tumors (0.45 [0.21-0.97], p-trend = .04 per 1 SD increase).
Conclusion: In this sample of predominantly AA CRC cases, we observed no association between vitamin D biomarkers in stored serum and subsequent more aggressive CRC molecular subtypes. More work is needed to characterize the relationship between vitamin D and expression of CRC tumor markers, which may help clarify the protective role of maintaining adequate vitamin D levels in association with CRC.

Abstract
Objectives While the importance of healthy lifestyles for preventing Alzheimer's disease and related dementias (ADRD) has been recognized, epidemiologic evidence remains limited from non-White or low-income populations who bear disproportionate burdens of ADRD. We examined the associations of major lifestyle factors, individually and together, with incident ADRD in a prospective cohort of primarily low-income Black and White Americans. Methods In the Southern Community Cohort Study, incident ADRD were identified using claims data among participants enrolled in Medicare for at least 12 consecutive months after age 65. Five lifestyle factors: tobacco smoking, alcohol consumption, leisure-time physical activity (LTPA), sleep hours, and diet quality, were each scored 0 (unhealthy), 1 (intermediate), or 2 (healthy) based on health guidelines. A composite lifestyle score was created by summing all scores. Cox regression was used to estimate hazard ratios (HRs) and 95% CIs, treating death as a competing risk and adjusting for potential confounders. Results Of 17,209 participants, 1,694 incident ADRD were identified during a median 4-year follow-up in claims data; the mean age at ADRD diagnosis was 74.0 years. Healthy lifestyles were individually associated with 11%–25% reduced risk of ADRD: multivariable-adjusted HR (95% CI) was 0.87 (0.76–0.99) for never vs. current smoking, 0.81 (0.72–0.92) for low-to-moderate vs. no alcohol consumption, 0.89 (0.77–1.03) for ≥150 minutes of moderate or ≥75 minutes of vigorous LTPA per week vs. none, 0.75 (0.64–0.87) for 7–9 hours vs. >9 hours of sleep, and 0.85 (0.75–0.96) for the highest vs. lowest tertiles of Healthy Eating Index. The composite lifestyle score showed a dose-response association with up to 36% reduced risk of ADRD: HRs (95% CIs) across quartiles were 1 (ref), 0.88 (0.77–0.99), 0.79 (0.70–0.90), and 0.64 (0.55–0.74); p-trend < 0.001. The beneficial associations were observed regardless of participants’ sociodemographics (e.g., race/ethnicity, education, and income) and health conditions (e.g., history of cardiometabolic diseases and depression). Conclusions Our findings support the importance of healthy lifestyles for ADRD prevention among socioeconomically disadvantaged Americans to reduce the growing burden and disparities posted by ADRD.

Abstract
In a low-income cohort in the Southeastern United States, 5% of participants avoided emergency medical care during the coronavirus disease 2019 pandemic, primarily due to fear and visitor restrictions. Younger age, self-perceived lower health status, lack of a personal doctor, and decreased income were associated with greater likelihood of deferring emergency care.

Abstract
Background: Widespread disruptions of medical care to mitigate COVID-19 spread and reduce burden on healthcare systems may have deleterious public health consequences. Design and methods: To examine factors contributing to healthcare interruptions during the pandemic, we conducted a COVID-19 impact survey between 10/7-12/14/2020 among participants of the Southern Community Cohort Study, which primarily enrolled lowincome individuals in 12 southeastern states from 2002-2009. COVID survey data were combined with baseline and follow-up data. Results: Among 4463 respondents, 40% reported having missed/delayed a health appointment during the pandemic; the common reason was provider-initiated cancellation or delay (63%). In a multivariable model, female sex was the strongest independent predictor of interrupted care, with odds ratio (OR) 1.63 (95% confidence interval [CI] 1.40-1.89). Those with higher education (OR 1.27; 95% CI 1.05-1.54 for college graduate vs ≤high school) and household income (OR 1.47; 95% CI 1.16-1.86 for >$50,000 vs <$15,000) were at significantly increased odds of missing healthcare. Having greater perceived risk for acquiring (OR 1.42; 95% CI 1.17-1.72) or dying from COVID-19 (OR 1.25; 95% CI 1.04-1.51) also significantly increased odds of missed/delayed healthcare. Age was inversely associated with missed healthcare among men (OR for 5-year increase in age 0.88; 95% CI 0.80-0.96) but not women (OR 0.97; 95% CI 0.91-1.04; P-interaction=0.04). Neither race/ethnicity nor comorbidities were associated with interrupted healthcare. Conclusions: Disruptions to healthcare disproportionately affected women and were primarily driven by health system-initiated deferrals and individual perceptions of COVID-19 risk, rather than medical co-morbidities or other traditional barriers to healthcare access. Significance for public health Lapses in routine medical care for chronic conditions and preventative healthcare due to the COVID-19 pandemic may have long-term adverse public health effects. These effects may be exacerbated among low-income individuals in the southeastern US who already experience higher rates of chronic disease and poor health outcomes. This study finds that the main drivers of healthcare lapses during the pandemic originate from the healthcare system through provider-initiated cancellations and from individual perceptions regarding the risk of contracting and surviving COVID-19, rather than medical comorbidities. The findings further identify a need for outreach efforts to re-engage patients in chronic and preventative care, as well as characteristics of groups that will benefit from targeted population-based interventions, including women.

Abstract
BACKGROUND Various carotenoids in circulation, including isomers, may have different influences on cancer risk. METHODS We conducted a nested case-control study including 343 incident prostate cancer cases and 640 controls individually matched on age, race, study site, and time of blood collection. Carotenoids investigated were carotene, cryptoxanthin, lycopene, dihydrolycopene, lutein, anhydrolutein, and zeaxanthin, including α versus β configurations and cis versus trans isomers. General linear model and conditional logistic regression were applied to evaluate associations for prostate cancer risk, with adjustment for potential confounders. We conducted additional analyses with further stratification by race, multivitamin use, and smoking status. RESULTS Case-control differences were found in carotenoid subtype levels, although not all reached the multiple comparison adjusted threshold for significance. Plasma lycopene [ORT1 vs. T3 = 0.51; 95% confidence interval (CI), 0.29-0.87; P trend = 0.014], dihydrolycopene (ORT1 vs. T3 = 0.37; 95% CI, 0.18-0.74; P trend = 0.006), and cis-anhydrolutein (ORT1 vs. T3 = 0.57; 95% CI, 0.33-0.96; P trend = 0.037) were inversely, while β-trans-carotene (ORT1 vs. T3 = 2.13; 95% CI, 1.32-3.43; P trend = 0.002) and trans-lutein (ORT1 vs. T3, 1.86; 95% CI, 1.20-2.88; P trend = 0.006) were positively associated with prostate cancer risk. Stratified analyses showed inverse associations of lycopene, dihydrolycopene, and cis-anhydrolutein with prostate cancer risk in subjects without multivitamin use; lycopene and dihydrolycopene in African-Americans and current smokers; and dihydrolycopene in nonsmokers. Positive associations of β-trans-carotene and trans-lutein were observed in African-Americans, nonsmokers, and multivitamin users. CONCLUSIONS The associations of carotenoids with risk of prostate cancer differed by carotenoid subtypes. IMPACT Public health recommendations on carotenoid intakes for prostate cancer prevention should take subtypes and isomers into consideration.

Abstract
Depression is a leading cause of disability in the United States, but its impact on mortality rates among racially diverse populations of low socioeconomic status is largely unknown. Using data from the Southern Community Cohort Study, 2002-2015, we prospectively evaluated the associations of depressive symptoms with all-cause and cause-specific mortality in 67,781 Black (72.3%) and White (27.7%) adults, a population predominantly with a low socioeconomic status. Baseline depressive symptoms were assessed using the 10-item Center for Epidemiological Studies Depression Scale. The median follow-up time was 10.0 years. Multivariate Cox regression was used to estimate hazard ratios and 95% confidence intervals for death in association with depressive symptoms. Mild, moderate, and severe depressive symptoms were associated with increased all-cause (hazard ratio (HR) = 1.12, 95% confidence interval (CI): 1.03, 1.22; HR = 1.17, 95% CI: 1.06, 1.29; HR = 1.15, 95% CI: 1.03, 1.28, respectively) and cardiovascular disease-associated death (HR = 1.23, 95% CI: 1.05, 1.44; HR = 1.18, 95% CI: 0.98, 1.42; HR = 1.43, 95% CI: 1.17, 1.75, respectively) in Whites but not in Blacks (P for interaction < 0.001, for both). Mild, moderate, or severe depressive symptoms were associated with increased rates of external-cause mortality in both races (HR = 1.24, 95% CI: 1.05, 1.46; HR = 1.31, 95% CI: 1.06, 1.61; HR = 1.42, 95% CI: 1.11, 1.81, respectively; for all study subjects, P for interaction = 0.48). No association was observed for cancer-associated deaths. Our study showed that the association between depression and death differed by race and cause of death in individuals with a low socioeconomic status.

Abstract
BACKGROUND The association of aspirin use with prostate cancer has been investigated, but few studies included African-American men. Here, we analyzed the relationship of aspirin intake with prostate cancer risk and mortality among African-American men in the Southern Community Cohort Study (SCCS). METHODS SCCS recruited 22,426 African-American men between 2002 and 2009. Aspirin use was assessed at enrollment. Our exposures of interest were any aspirin use (regular strength, low-dose or baby aspirin, or half tablets of aspirin) and regular strength aspirin. Each exposure variable was compared with nonusers. Associations between aspirin use and prostate cancer risk and mortality were examined with Cox proportional hazards models. RESULTS At enrollment, 5,486 men (25.1%) reported taking any aspirin and 2,634 men (12.1%) reported regular strength aspirin use. During follow-up (median, 13 years), 1,058 men developed prostate cancer, including 103 prostate cancer-specific deaths. Aspirin use was not associated with prostate cancer development [adjusted HR, 1.07; 95% confidence interval (CI), 0.92-1.25 for any aspirin use and HR, 0.97; 95% CI, 0.78-1.19 for regular strength aspirin], but was suggestively associated with reduced prostate cancer mortality (HR, 0.66; 95% CI, 0.39-1.14 for any aspirin use and HR, 0.41; 95% CI, 0.17-1.00 for regular strength aspirin). CONCLUSIONS Aspirin use at enrollment was tentatively associated with reduced prostate cancer mortality, but not risk, among African-American men in SCCS. IMPACT Prospective SCCS data suggest that aspirin use may help prevent lethal prostate cancer among this high-risk group of men.

Abstract
IMPORTANCE Colorectal cancer (CRC) screening is rarely studied in populations who may face additional barriers to participate in cancer screening, such as African American individuals and individuals with low socioeconomic status (SES). OBJECTIVE To examine the associations of CRC screening and modalities with CRC incidence and mortality by race and SES. DESIGN, SETTING, AND PARTICIPANTS This cohort study used data from the Southern Community Cohort Study, which enrolled more than 85 000 participants from community health centers or stratified random sampling of the general population in 12 states in the southeastern United States. The present study included data from cohort members who were eligible for CRC screening as recommended by expert organizations based on age and family history. Participants completed questionnaires from 2002 to 2009 and were contacted again from 2008 to 2012. Linkages to state cancer registries and the National Death Index as of December 31, 2016, identified incident CRC and vital status. Data analysis was performed from January 1, 2018, to October 30, 2019. MAIN OUTCOMES AND MEASURES Incident CRC (n = 632) and mortality (n = 10 003). Cox proportional hazards regression models evaluated associations between screening modalities and CRC risk and mortality. Information on fecal occult blood test use was only obtained on the follow-up questionnaire. Self-identified race was measured as African American/black, white, or other, and SES was defined by household income. RESULTS This study included 47 596 participants (median baseline age, 54 years [interquartile range, 10 years]; 32 185 [67.6%] African American; 28 884 [60.7%] female; and 26 075 [54.8%] with household income <$15 000). A total of 24 432 participants (63.9%) had never undergone CRC testing at baseline. The CRC testing assessed at baseline and follow-up interviews was associated with significant CRC risk reduction (hazard ratio [HR], 0.55; 95% CI, 0.44-0.70 for ever colonoscopy at baseline). Results were similar in analyses stratified by race (African American: HR, 0.65; 95% CI, 0.50-0.85; white: HR, 0.44; 95% CI, 0.27-0.70) and household income (<$15 000: HR, 0.63; 95% CI, 0.46-0.86, ≥$15 000: HR, 0.49; 95% CI, 0.35-0.69). Ever sigmoidoscopy at baseline was associated with CRC risk reduction (HR, 0.66; 95% CI, 0.51-0.87), and undergoing fecal occult blood test in the interval between baseline and follow-up interview was associated with CRC risk reduction (HR, 0.75; 95% CI, 0.57-0.98). Inverse associations were also observed between CRC mortality and receipt of colonoscopy (HR for women, 0.39; 95% CI, 0.21-0.73; HR for men, 0.69; 95% CI, 0.40-1.18) and sigmoidoscopy (HR for women, 0.37; 95% CI, 0.16-0.85; HR for men, 0.82; 95% CI, 0.46-1.47); however, the association did not extend to fecal occult blood test (HR for women, 1.02; 95% CI, 0.62-1.70; HR for men, 1.03; 95% CI, 0.55-1.93). CONCLUSIONS AND RELEVANCE In this study, CRC test rates were low among African American individuals and those with low SES. The findings suggest that screening, particularly with colonoscopy, is significantly associated with reduced risk of CRC and mortality. The CRC disparities experienced by individuals with low SES and African American individuals may be lessened by improving access to and uptake of CRC screening.

Abstract
Increasing evidence indicates the significant racial difference in gut, vaginal, and skin microbiomes. However, little is known regarding the racial difference in the oral microbiome. In this study, deep sequencing of 16S rRNA genes was utilized to assess the oral microbiome in mouth rinse samples of 1,058 African-Americans (AAs) and 558 European-Americans (EAs) from the Southern Community Cohort Study. Generally, AAs had a higher species richness than EAs, with P = 5.28 × 10-14 (Wilcoxon rank sum test) for Faith's phylogenetic diversity index. A significant difference in overall microbiome composition was observed between AAs and EAs, with P = 5.94 × 10-4 (MiRKAT) for the weighted UniFrac distance matrix. We also found 32 bacterial taxa showing a significant differential abundance or prevalence between the two racial groups at a Bonferroni-corrected P < 0.05 in linear or logistic regression analyses. Generally, AAs showed a higher abundance of Bacteroidetes and a lower abundance of Actinobacteria and Firmicutes Interestingly, four periodontal pathogens, Porphyromonas gingivalis, Prevotella intermedia, Treponema denticola, and Filifactor alocis, were more prevalent among AAs than among EAs, with Bonferroni-corrected P values of 5.23 × 10-6, 4.47 × 10-6, 1.08 × 10-3, and 4.49 × 10-5, respectively. In addition, all of these 32 taxa were significantly correlated with the percentage of genetic African ancestry. These findings call for research to understand how the racial difference in oral microbiome influences the health disparity.IMPORTANCE In this systemic investigation of racial differences in the oral microbiome using a large data set, we disclosed the significant differences in the oral microbial richness/evenness, as well as in the overall microbial composition, between African-Americans and European-Americans. We also found multiple oral bacterial taxa, including several preidentified oral pathogens, showing a significant different abundance or prevalence between African-Americans and European-Americans. Furthermore, these taxa were consistently found to be associated with the percentage of genetic African ancestry. Our findings warrant further research to understand how the racial difference in the oral microbiome influences the health disparity.

Abstract
Few studies have evaluated the relationship of oral microbiome with obesity. We investigated the oral microbiome among 647 obese and 969 non-obese individuals from the Southern Community Cohort Study, through 16S rRNA gene sequencing in mouth rinse samples. We first investigated 16 taxa in two probiotic genera, Bifidobacterium and Lactobacillus. Among them, eight showed nominal associations with obesity (P < 0.05). Especially, Bifidobacterium (odds ratio [OR] = 0.67, 95% confidence interval [CI]:0.54, 0.83) and Bifidobacterium longum (OR = 0.57, 95% CI: 0.45, 0.73) were significantly associated with decreased obesity prevalence with false-discovery rate (FDR)-corrected P of 0.01 and 5.41 × 10-4, respectively. Multiple other bacterial taxa were also significantly associated with obesity prevalence at FDR-corrected P < 0.05. Among them, five in Firmicutes and two respectively in Actinobacteria and Proteobacteria were significantly associated with increased obesity prevalence. Significant associations with decreased obesity prevalence were observed for two taxa respectively in Actinobacteria and Firmicutes. Most of these taxa were associated with body mass index at study enrollment and weight gain during adulthood. Also, most of these associations were observed in both European- and African-Americans. Our findings indicate that multiple oral bacterial taxa, including several probiotic taxa, were significantly associated with obesity.

Abstract
BACKGROUND Precision interventions using biological data may enhance smoking treatment, yet are understudied among smokers who are disproportionately burdened by smoking-related disease. METHODS We surveyed smokers in the NCI-sponsored Southern Community Cohort Study, consisting primarily of African-American, low-income adults. Seven items assessed attitudes toward aspects of precision smoking treatment, from undergoing tests to acting on results. Items were dichotomized as favorable (5 = strongly agree/4 = agree) versus less favorable (1 = strongly disagree/2 = disagree/3 = neutral); a summary score reflecting generalized attitudes was also computed. Multivariable logistic regression tested independent associations of motivation (precontemplation, contemplation, and preparation) and confidence in quitting (low, medium, and high) with generalized attitudes, controlling for sociodemographic factors and nicotine dependence. RESULTS More than 70% of respondents endorsed favorable generalized attitudes toward precision medicine, with individual item favorability ranging from 64% to 83%. Smokers holding favorable generalized attitudes reported higher income and education (P < 0.05). Predicted probabilities of favorable generalized attitudes ranged from 63% to 75% across motivation levels [contemplation vs. precontemplation: adjusted odds ratio (AOR) = 2.10, 95% confidence interval (CI), 1.36-3.25, P = 0.001; preparation vs. precontemplation: AOR = 1.83, 95% CI, 1.20-2.78, P = 0.005; contemplation vs. preparation: AOR = 1.15, 95% CI, 0.75-1.77, P = 0.52] and from 59% to 78% across confidence (medium vs. low: AOR = 1.91, 95% CI, 1.19-3.07, P = 0.007; high vs. low: AOR = 2.62, 95% CI, 1.68-4.10, P < 0.001; medium vs. high: AOR = 0.73, 95% CI, 0.48-1.11, P = 0.14). CONCLUSIONS Among disproportionately burdened community smokers, most hold favorable attitudes toward precision smoking treatment. Individuals with lower motivation and confidence to quit may benefit from additional intervention to engage with precision smoking treatment. IMPACT Predominantly favorable attitudes toward precision smoking treatment suggest promise for future research testing their effectiveness and implementation.

Abstract
BACKGROUND Prostate-specific antigen (PSA) measurement in midlife predicts long-term prostate cancer (PCa) mortality among white men. OBJECTIVE To determine whether baseline PSA level during midlife predicts risk of aggressive PCa in black men. DESIGN, SETTING, AND PARTICIPANTS Nested case-control study among black men in the Southern Community Cohort Study recruited between 2002 and 2009. A prospective cohort in the southeastern USA with recruitment from community health centers. A total of 197 incident PCa patients aged 40-64 yr at study entry and 569 controls matched on age, date of blood draw, and site of enrollment. Total PSA was measured in blood collected and stored at enrollment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Total and aggressive PCa (91 aggressive: Gleason ≥7, American Joint Committee on Cancer stage III/IV, or PCa-specific death). Exact conditional logistic regression estimated odds ratios (ORs) with 95% confidence intervals (CIs) for PCa by category of baseline PSA. RESULTS AND LIMITATIONS Median PSA among controls was 0.72, 0.80, 0.94, and 1.03ng/ml for age groups 40-49, 50-54, 55-59, and 60-64 yr, respectively; 90th percentile levels were 1.68, 1.85, 2.73, and 3.33ng/ml. Furthermore, 95% of total and 97% of aggressive cases had baseline PSA above the age-specific median. Median follow-up was 9 yr. The OR for total PCa comparing PSA >90th percentile versus ≤median was 83.6 (95% CI, 21.2-539) for 40-54 yr and 71.7 (95% CI, 23.3-288) for 55-64 yr. For aggressive cancer, ORs were 174 (95% CI, 32.3-infinity) for 40-54 yr and 51.8 (95% CI, 11.0-519) for 55-64 yr. A composite endpoint of aggressive PCa based on stage, grade, and mortality was used and is a limitation. CONCLUSIONS PSA levels in midlife strongly predicted total and aggressive PCa among black men. PSA levels among controls were similar to those among white controls in prior studies. PATIENT SUMMARY Prostate-specific antigen (PSA) level during midlife strongly predicted future development of aggressive prostate cancer among black men. Targeted screening based on a midlife PSA might identify men at high risk while minimizing screening in those men at low risk.

Abstract
INTRODUCTION Considering the joint association of neighborhood socioeconomic environment and individual-level health behaviors with health outcomes may help officials design effective disease prevention strategies. This study evaluates the joint influences of neighborhood socioeconomic environment and individual health behaviors on mortality in a cohort primarily comprising people with low individual-level SES. METHODS The prospective Southern Community Cohort Study includes 77,896 white and African American participants recruited in the years 2002-2009; 55% of participants had a household income <$15,000 at baseline interview. Mortality from cancer (n=2,471), cardiovascular diseases (n=3,005), and all-causes (n=10,099) was identified from the National Death Index through December 31, 2013 (median follow-up, 8 years). Data were analyzed in 2016 and 2017. Associations were assessed between mortality, a neighborhood deprivation index composed of 11 census tract-level variables, five health behaviors, and a composite healthy lifestyle score. RESULTS Living in a neighborhood with the greatest socioeconomic disadvantage was associated with higher all-cause mortality in both men (hazard ratio=1.41, 95% CI=1.27, 1.57) and women (hazard ratio=1.77, 95% CI=1.57, 2.00). Associations were attenuated after adjustment for individual-level SES and major risk factors (hazard ratio for men=1.09, 95% CI=0.98, 1.22, and hazard ratio for women=1.26, 95% CI=1.12, 1.42). The dose-response association between neighborhood disadvantage and mortality was less apparent among smokers. Nevertheless, individuals who lived in disadvantaged neighborhoods and had the unhealthiest lifestyle scores experienced the highest mortality. CONCLUSIONS Disadvantaged neighborhood socioeconomic environments are associated with increased mortality in a cohort of individuals of low SES. Positive individual-level health behaviors may help negate the adverse effect of disadvantage on mortality.

Abstract
BACKGROUND AND OBJECTIVE The oral microbiome may help to maintain systemic health, including how it affects blood glucose levels; however, direct evidence linking the oral microbiome with diabetes is lacking. MATERIAL AND METHODS We compared the oral microbiome profiles of 98 participants with incident diabetes, 99 obese non-diabetics and 97 normal weight non-diabetics, via deep sequencing of the 16S rRNA gene. RESULTS We found that the phylum Actinobacteria was present significantly less abundant among patients with diabetes than among the controls (p = 3.9 × 10-3 ); the odds ratio (OR) and 95% confidence interval (CI) was 0.27 (0.11-0.66) for those individuals who had relative abundance higher than the median value. Within this phylum, five families and seven genera were observed, and most of them were less abundant among patients with diabetes. Notably, genera Actinomyces and Atopobium were associated with 66% and 72% decreased risk of diabetes with p-values of 8.9 × 10-3 and 7.4 × 10-3 , respectively. Stratified analyses by race showed that most taxa in this phylum were associated with diabetes in both black and white participants. This phylum was also less abundant among non-diabetic obese subjects compared to normal weight individuals, particularly genera Mobiluncus, Corynebacterium and Bifidobacterium, which showed p < 0.05. CONCLUSION Our study revealed that multiple bacteria taxa in the phylum Actinobacteria are associated with the risk of type 2 diabetes. Some are also associated with the prevalence of obesity, suggesting that the oral microbiome may play an important role in diabetes etiology.

Abstract
Abstract
Purpose: Animal and cell line studies provide biologic plausibility that circulating vitamin D may reduce colorectal cancer risk. However, studies in humans have been inconclusive, and few have considered the role of vitamin D binding protein and free vitamin D. We comprehensively evaluated whether vitamin D biomarkers predict risk of colorectal cancer by measuring circulating level of vitamin D binding protein, and total and free 25-hydroxyvitamin D in pre-diagnostic blood serum samples. We used data from a nested case-control study that includes a large number of African Americans, who typically have lower levels of total vitamin D than those of European descent, and who have been understudied in previous investigations.
Methods: Participants of the nested case-control study were drawn from the Southern Community Cohort Study, a prospective cohort study primarily comprised of low-income white and African Americans. Participants aged 40-79 were enrolled into the study from 2002 to 2009, and provided information on lifestyle factors and demographics. Cases were participants who were diagnosed with an incident colorectal cancer after study enrollment and donated a blood sample for the study. Controls were selected through incidence density sampling of the cohort members who had donated a blood sample and were free of any cancer except skin cancer at the time of the case's diagnosis. Controls were individually matched to cases by age at diagnosis, sex, and race at a ratio of two controls for each case. A total of 298 cases and 580 controls were included in the current study. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between vitamin D biomarker levels and colorectal cancer risk.
Results: ORs for the associations between total and free 25-hydroxyvitamin D with colorectal cancer risk indicated inverse associations, although all confidence intervals crossed unity. More apparent associations were observed among cases with greater than three years between blood draw and diagnosis. Among these subjects, the adjusted ORs for the comparison between participants in the highest tertile of free 25-hydroxyvitamin D levels compared to those in the lowest tertile were 0.65 (95%CI: 0.38,1.11) for all subjects and 0.46 (95%CI: 0.25,0.84) for African Americans. In participants with greater than three years between blood draw and diagnosis, the inverse association pattern was seen in all strata defined by sex, body mass index, and anatomic site, although not all analyses reached significance at P ≤ 0.05. Small samples size in analyses restricted to whites resulted in unstable estimates. Vitamin D binding protein was not associated with colorectal cancer risk.
Conclusions: In our study, total and free 25-hydroxyvitamin D are inversely associated with colorectal cancer risk, particularly in African Americans, suggesting a potential role of vitamin D in colorectal cancer prevention.

Abstract
INTRODUCTION African Americans and low-income whites have higher mortality than the U.S. general population. This study prospectively investigated the combined influence of major lifestyle factors and poverty on mortality in this vulnerable population. METHODS Data were collected in 2002-2009 from 79,101 Southern Community Cohort Study participants, of which 67% were African American and 55% had household incomes <$15,000. Mortality outcomes were identified from the National Death Index though December 31, 2011 (data analyzed in 2014-2015). Healthy behavior scores were created based on tobacco smoking, alcohol intake, diet, physical activity, and sedentary time. The primary analysis was performed based on the score created by counting each participant as having met/not met public health guidelines for each behavior. RESULTS Healthy behavior scores were associated with reduced cancer, cardiovascular disease, and all-cause mortality. Associations were stronger for whites than African Americans: hazard ratios for all-cause mortality comparing participants meeting four or five guidelines versus participants meeting zero were 0.41 (95% CI=0.30, 0.55) for African American men; 0.36 (95% CI=0.24, 0.55) for white men; 0.46 (95% CI=0.36, 0.59) for African American women; and 0.27 (95% CI=0.18, 0.43) for white women. The association between healthy lifestyle and all-cause mortality was weaker among those with incomes <$15,000 than those with higher income, particularly in men (p<0.05 for interaction). CONCLUSIONS This study demonstrates the importance of health behaviors on mortality among all groups, but highlights the need for additional research to identify factors contributing to high risk of mortality among low-income and African American populations.

Abstract
BACKGROUND While studies have shown that poor oral health status may increase the risk of cancer, evidence of a specific association with the risk of colorectal cancer (CRC) is inconclusive. We evaluated the association between oral health and CRC risk using data from three large cohorts: the Shanghai Men's Health Study (SMHS), the Shanghai Women's Health Study (SWHS), and the Southern Community Cohort Study (SCCS), and carried out a meta-analysis of results from other relevant published studies. PATIENTS AND METHODS This study applied a nested case-control study design and included 825 cases/3298 controls from the SMHS/SWHS and 238 cases/2258 controls from the SCCS. The association between oral health status (i.e. tooth loss/tooth decay) and CRC risk was assessed using conditional logistic regression models. A meta-analysis was carried out based on results from the present study and three published studies. RESULTS We found that tooth loss was not associated with increased risk of CRC. ORs and respective 95% CIs associated with loss of 1-5, 6-10, and >10 teeth compared with those with full teeth are 0.87 (0.69-1.10), 0.93 (0.70-1.24), and 0.85 (0.66-1.11) among SMHS/SWHS participants; and 1.13 (0.72-1.79), 0.87 (0.52-1.43), and 1.00 (0.63-1.58) for those with loss of 1-4, 5-10, and >10 teeth among SCCS participants. Data regarding tooth decay were available in the SCCS, but were not associated with CRC risk. Meta-analysis confirmed the null association between tooth loss/periodontal disease and CRC risk (OR 1.05, 95% CI 0.86-1.29). CONCLUSION In this analysis of three cohorts and a meta-analysis, we found no evidence supporting an association between oral health and CRC risk.

Abstract
Abstract
Background: Public health and cancer prevention guidelines recommend healthy behaviors to decrease overall cancer risk. The impact of cancer prevention guidelines on cancer incidence has been rarely studied in low-income Whites and African Americans.
Design: We quantified the association of meeting current American Cancer Society cancer prevention guidelines, as measured by non-smoking, none to moderate alcohol intake, higher diet quality, and regular physical activity with total and site-specific cancer incidence. Data were obtained at enrollment from 73,022 adults age 40-79, without a previous cancer diagnosis, participating in the Southern Community Cohort Study. The Southern Community Cohort Study is a prospective cohort study that enrolled participants during 2002-2009, in 12 southeastern US states via Community Health Centers (86%) or stratified random sampling of the general population (14%). Fifty-six percent of the cohort has a household income<$15,000. The median follow-up time for cohort members was 6 years.
Exposures: We created a healthy guidelines score by counting the number of cancer prevention guidelines each participant met for tobacco smoking, alcohol intake, diet, and physical activity.
Outcomes: Breast (N = 503), prostate (N = 479), lung (N = 621), colorectal (N = 333), other (N = 1374), and total cancer incidence (N = 3,310) were identified from state cancer registries through December 31, 2011.
Results: Meeting fewer cancer prevention guidelines was associated with increased cancer incidence: hazard ratios (HRs) for overall cancer incidence comparing participants with four guidelines met vs three, two, one, or zero guidelines were 1.04 (95% confidence interval (CI): 0.79-1.38), 1.23 (0.94-1.61), 1.52 (1.16-1.98), and 1.86 (1.40-2.46), respectively. Tests for interactions with race and sex were not statistically significant. The association between the healthy guidelines score and total cancer incidence was most apparent in participants with normal weight (body mass index 18.5-24.9 kg/m2) (P-interaction = 0.02). The strongest association was observed for lung cancer risk largely attributable to the sizable numbers of current smokers in the cohort; the HR for participants meeting no guideline recommendations compared to participants meeting three or four healthy guidelines was 6.78 (95%CI: 4.24-10.84). Weaker and non-significant associations were observed between the healthy guidelines score and breast, colorectal, and prostate cancer risk (all P-trends>0.10).
Conclusions: Meeting current public health guidelines is associated with substantial reductions in cancer incidence. This study provides support for individual lifestyle modification to reduce cancer incidence in this under-served population.

Abstract
BACKGROUND A healthy diet, as defined by the US Dietary Guidelines for Americans (DGA), has been associated with lower morbidity and mortality from major chronic diseases in studies conducted in predominantly non-Hispanic white individuals. It is unknown whether this association can be extrapolated to African-Americans and low-income populations. METHODS AND FINDINGS We examined the associations of adherence to the DGA with total and cause-specific mortality in the Southern Community Cohort Study, a prospective study that recruited 84,735 American adults, aged 40-79 y, from 12 southeastern US states during 2002-2009, mostly through community health centers that serve low-income populations. The present analysis included 50,434 African-Americans, 24,054 white individuals, and 3,084 individuals of other racial/ethnic groups, among whom 42,759 participants had an annual household income less than US$15,000. Usual dietary intakes were assessed using a validated food frequency questionnaire at baseline. Adherence to the DGA was measured by the Healthy Eating Index (HEI), 2010 and 2005 editions (HEI-2010 and HEI-2005, respectively). During a mean follow-up of 6.2 y, 6,906 deaths were identified, including 2,244 from cardiovascular disease, 1,794 from cancer, and 2,550 from other diseases. A higher HEI-2010 score was associated with lower risks of disease death, with adjusted hazard ratios (HRs) of 0.80 (95% CI, 0.73-0.86) for all-disease mortality, 0.81 (95% CI, 0.70-0.94) for cardiovascular disease mortality, 0.81 (95% CI, 0.69-0.95) for cancer mortality, and 0.77 (95% CI, 0.67-0.88) for other disease mortality, when comparing the highest quintile with the lowest (all p-values for trend < 0.05). Similar inverse associations between HEI-2010 score and mortality were observed regardless of sex, race, and income (all p-values for interaction > 0.50). Several component scores in the HEI-2010, including whole grains, dairy, seafood and plant proteins, and ratio of unsaturated to saturated fatty acids, showed significant inverse associations with total mortality. HEI-2005 score was also associated with lower disease mortality, with a HR of 0.86 (95% CI, 0.79-0.93) when comparing extreme quintiles. Given the observational study design, however, residual confounding cannot be completely ruled out. In addition, future studies are needed to evaluate the generalizability of these findings to African-Americans of other socioeconomic status. CONCLUSIONS Our results showed, to our knowledge for the first time, that adherence to the DGA was associated with lower total and cause-specific mortality in a low-income population, including a large proportion of African-Americans, living in the southeastern US.

Abstract
OBJECTIVE To assess potential health risks associated with work in a large motion picture film-processing facility. METHODS A retrospective cohort mortality study was conducted during 1960-2000 among 2646 film workers. Job family categories, created from detailed employee work history information, were used to evaluate chemical exposure patterns. RESULTS Overall mortality was as expected (standardized mortality ratio [SMR] = 1.1; 95% confidence interval [CI] = 1.0-1.2). Statistically significant associations were found for suicides (SMR = 2.0; 95% CI = 1.2-3.0) among the hourly workers and AIDS (SMR = 5.3; 95% CI = 1.7-12.3) among the administrative workers. Film developers had increases of respiratory cancer (SMR = 1.9; 95% CI = 1.1-3.0) and suicides (SMR = 2.4; 95% CI = 1.0-4.7), whereas film assemblers had an increase in suicides (SMR = 2.4; 95% CI = 1.2-4.4) only. CONCLUSIONS Excess deaths resulting from suicides and AIDS among the workforce suggest that nonoccupational influences may be involved in the mortality of this cohort and warrant further investigations.
