Abstract
We used the Southern Community Cohort Study of people residing in 12 states in the southeastern United States (n=38,200 participants) to examine associations between adverse childhood experiences (ACEs) and chronic disease risk. After adjustment for confounding, there were statistically significant positive associations for people reporting four or more ACEs relative to those reporting no ACEs, and this was true for all chronic diseases except hypertension. The most elevated risk was seen for depression when measured as a yes/no variable (odds ratio (OR) 2.84, 95% confidence interval (CI) 2.64-3.06) or when using the 10-item Center for Epidemiologic Student Depression (CESD) scale (OR 1.88, 95% CI 1.75-2.02). There were also statistically significant monotonic increases in risk with worsening ACE score for all chronic diseases except hypertension, cancer, and high cholesterol. The need to establish programs that build resilience during childhood is paramount for preventing chronic diseases that may result from childhood abuse, neglect, and household dysfunction.

Patterns and correlates of sleep duration in the Southern cohort community study. Sleep Med 2020; 75:459-467. [PMID: 32998092 DOI: 10.1016/j.sleep.2020.09.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 09/03/2020] [Accepted: 09/08/2020] [Indexed: 02/06/2023]
Abstract
OBJECTIVE To investigate whether race (African American (AA) and white) is associated with sleep duration among adults from low socioeconomic (SES) strata and whether SES status, lifestyle behaviors, or health conditions are associated with sleep duration within race-sex groups. METHODS This cross-sectional study includes 78,549 participants from the Southern Community Cohort Study (SCCS). Averaged daily sleep duration was assessed by weighted averages of self-reported sleep duration on weekdays and weekends. Adjusted odds ratios (ORs) of very short (<5 h/day), short (5-6 h/day), and long sleep (≥9 h/day) associated with pre-selected risk factors in each race-sex group were determined by multinomial logistic models. RESULTS The prevalence of very short and short sleep was similar among AAs (6.2% and 29.1%) and whites (6.5% and 29.1%). Long sleep was considerably more prevalent among AAs (19.3%) than whites (13.0%). Very short sleep was associated with lower education and family income, with stronger associations among whites. Higher physical activity levels significantly decreased odds for both very short (OR = 0.80) and long sleep (OR = 0.78). Smoking, alcohol use, and dietary intake were not associated with sleep duration. Regardless of race or sex, very short, short, and long sleep were significantly associated with self-reported health conditions, especially depression (ORs were 2.06, 1.33, and 1.38, respectively). CONCLUSIONS Sleep duration patterns differed between AAs and whites from the underrepresented SCCS population with low SES. Sleep duration was associated with several socioeconomic, health behaviors, and health conditions depending on race and sex.

Abstract
OBJECTIVE To determine associations of adverse childhood experiences (ACE) with adult health care utilization in an underserved, low-income population. METHODS Questionnaires on ACE were completed by 38,200 adults (mean age 54), two-thirds African American, recruited from community health centers (CHCs) across 12 Southeastern states. Odds ratios (ORs) and accompanying 95% confidence intervals (CIs) were computed. RESULTS The percentages reporting emergency room visits and doctor's office visits, with high chronic disease index scores, rose monotonically (ptrend<.001) with rising ACE score. Odds ratios (CIs) for those with four or more vs. zero ACEs were 1.37 (95% CI 1.27-1.47) for 1-10 times and 1.80 (95% CI 1.29-2.52) for more than 10 times ER visits, 1.37 (95% CI 1.18-1.59) for over 10 doctor's visits, and 2.29 (95% CI 2.06-2.54) for three or more chronic diseases. CONCLUSIONS High ACE levels were associated with greater chronic disease burden and greater health care utilization in adulthood. Long-lasting effects from ACE on the health care of underserved populations are indicated. There is an urgent need to train health care providers, patients, and their families on ACE effects and treatments for better health care outcomes.

Diabetes, obesity, and subsequent risk of postmenopausal breast cancer among white and black women in the Southern Community Cohort Study. Cancer Causes Control 2019; 30:425-433. [PMID: 30941541 PMCID: PMC6467525 DOI: 10.1007/s10552-019-01164-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Accepted: 03/26/2019] [Indexed: 12/29/2022]
Abstract
PURPOSE Meta-analyses have reported a small but positive association between diabetes and postmenopausal breast cancer risk, with summary relative risks of approximately 1.15. We analyzed data from the Southern Community Cohort Study (SCCS) following an underserved population with high diabetes prevalence to prospectively examine whether diabetes was associated with subsequent postmenopausal breast cancer risk and whether obesity modified this effect. METHODS Women with incident breast cancer were identified through linkage with state cancer registries and the National Death Index (213 white, 418 black cases). Person-years were calculated from date of entry into the SCCS until the earliest of date of breast cancer diagnosis, date of death, or date of last follow-up (8,277 white, 16,458 black noncases). Data on diabetes diagnosis were obtained through baseline and follow-up surveys. Cox regression was applied to examine the association between diabetes and postmenopausal breast cancer risk. RESULTS After adjustment for confounding, there was no association between self-reported diabetes and postmenopausal breast cancer risk among white (hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.75-1.40) or black (HR 1.00, 95% CI 0.81-1.22) women. Nor was there evidence that obesity modified the effect of diabetes on postmenopausal breast cancer in women of either race. CONCLUSIONS We found no evidence of the hypothesized increased risk of breast cancer among women with diabetes. The breast cancer risks among those with diabetes in this population suggest that the association between these two illnesses is complex.

Food intake of folate, folic acid and other B vitamins with lung cancer risk in a low-income population in the Southeastern United States. Eur J Nutr 2019; 59:671-683. [PMID: 30838435 DOI: 10.1007/s00394-019-01934-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Accepted: 02/18/2019] [Indexed: 12/19/2022]
Abstract
PURPOSE We prospectively examined associations of lung cancer risk with food intake of B vitamins involved in one-carbon metabolism and the use of folic acid-containing supplements among a low-income population of black and white adults in the Southeastern US. METHODS Within the Southern Community Cohort Study, we included 1064 incident lung cancer cases among 68,236 participants aged 40-79 years at study enrollment. Food intake and the use of folic acid-containing supplements were assessed using a validated food frequency questionnaire at study enrollment. Multivariate Cox regression was used to estimate hazards ratios (HRs) and the 95% confidence intervals (CIs). RESULTS Folate and/or folic acid intake from food were not associated with lung cancer risk; HRs (95% CI) for highest compared with lowest quartile were 1.08 (0.91-1.29) for total dietary folate, 1.00 (0.84-1.19) for food folate, and 1.09 (0.91-1.30) for food folic acid, respectively. Similarly, no associations were observed after stratifying by sex, race and smoking status, except for a positive association with total dietary folate intake among black women (HR 1.46, 95% CI 1.04-2.05 for the highest quartile compared with the lowest quartile, P trend = 0.02). Neither the use of folic acid-containing supplements nor food intake of vitamin B6, vitamin B12 and riboflavin were associated with lung cancer risk. CONCLUSIONS Our findings do not support a protective effect of folate or folic acid for lung cancer prevention in a low-income population of black and white adults in the Southeastern US. Our finding of a positive association with total dietary folate intake among black women needs to be interpreted with caution and replicated in other studies.

Abstract
Limited information is available regarding the effects of physical activity on risks of cardiometabolic diseases among obese African American adults. We conducted a church-based 12-week weight control and cardiometabolic risk reduction intervention (n=30, 22 females, 56.7±11.4 years old, BMI 37.4±6.7 kg/m2), after which body weight was slightly reduced (98.3±18.4 and 97.3±19 kg, p=.052); body fat percentage was significantly decreased among males (34.7±8.9 to 28.5±8.4 %; p=.049); and walking steps were increased, but not significantly. Among measured cardiometabolic risk biomarkers, hemoglobin A1c (HbA1c) was decreased significantly (6.8±1.1 to 6.1±1.1%; p=.0004) while time spent in sedentary behaviors was associated with less favorable change in total cholesterol (β=11.49, SE=3.55, p=.003) and tumor necrosis factor (TNF-α, β=0.3, SE=0.13, p=.038). Our study shows that adiposity reduction was feasible through a short-term healthy lifestyle program for obese African American adults, and suggests that reducing sedentary behaviors through light physical activity might lead to a decrease in cardiovascular risks.

The obesity epidemic and rising diabetes incidence in a low-income racially diverse southern US cohort. PLoS One 2018; 13:e0190993. [PMID: 29324894 PMCID: PMC5764338 DOI: 10.1371/journal.pone.0190993] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Accepted: 12/22/2017] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Obesity is known to be a major risk factor for diabetes, but the magnitude of risk and variation between blacks and whites are less well documented in populations heavily affected by obesity. Herein we assess rates and risks of incident diabetes in a diverse southern population where obesity is common. METHODS A total of 24,000 black and 14,064 white adults aged 40-79 in the Southern Community Cohort Study with no self-reported diabetes at study enrollment during 2002-2009 was followed for up to 10 (median 4.5) years. Incidence rates, odds ratios (OR) and accompanying 95% confidence intervals (CI) for medication-treated incident diabetes were determined according to body mass index (BMI) and other characteristics, including tobacco and alcohol consumption, healthy eating and physical activity indices, and socioeconomic status (SES). RESULTS Risk of incident diabetes rose monotonically with increasing BMI, but the trends differed between blacks and whites (pinteraction < .0001). Adjusted ORs (CIs) for diabetes among those with BMI≥40 vs 20-25 kg/m2 were 11.9 (8.4-16.8) for whites and 4.0 (3.3-4.8) for blacks. Diabetes incidence was more than twice as high among blacks than whites of normal BMI, but the racial difference became attenuated as BMI rose, with estimated 5-year probabilities of developing diabetes approaching 20% for both blacks and whites with BMI≥40 kg/m2. Diabetes risk was also associated with low SES, significantly (pinteraction≤.02) more so for whites, current cigarette smoking, and lower healthy eating and physical activity indices, although high BMI remained the predominant risk factor among both blacks and whites. From baseline prevalence and 20-year projections of the incidence trends, we estimate that the large majority of surviving cohort participants with BMI≥40 kg/m2 will be diagnosed with diabetes. CONCLUSIONS Even using conservative criteria to ascertain diabetes incidence (i.e., requiring diabetes medication use and ignoring undiagnosed cases), rates of obesity-associated diabetes were exceptionally high in this low-income adult population. The findings indicate that effective strategies to halt the rising prevalence of obesity are needed to avoid substantial increases in diabetes in coming years.

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
The enrollment of African American women into cancer prevention trials (CPTs) continues to be low despite their higher cancer mortality rates. Clinical trials are vital to the discovery of new prevention, diagnostic, and treatment methods that improve cancer outcomes. This study addressed attitudes and beliefs associated with the sub optimal participation of African American women in CPTs through the development and pretesting of an educational tool. The use of community-engaged research (CER) in the formative phase of this study was the basis for developing an audio-card. Cultural and linguistic elements were incorporated into the tool's audio and written messages, and visual images highlighted the importance of CPT participation among African American women. The CPT beliefs and behavioral intent of 30 African American women who received information from the audio-card were compared with 30 controls. Findings indicated statistically significant differences at posttest between the control and treatment groups in personal value (p = .03), social influence (p = .03), and personal barriers (p = .0001); personal barriers in the pretest group also demonstrated significant differences (p = .009). Consideration of cultural context and language needs of populations are vital to the development and design of effective health promoting tools.

Abstract
Objective The pilot study was intended to test the feasibility of a multiple-component lifestyle intervention targeting African American adults in a weight control and cardiometabolic risk reduction program on diet, activity, and stress, using community-engagement principles. Methods Applying mixed qualitative and quantitative measures, the intervention had a two-part sequential study design consisting of 12 weekly small group sessions that provided individual and group counseling in nutrition, exercise, and mindfulness, while incorporating focus group and interactive techniques to learn about barriers and acceptable practices for this population. The program was implemented at an African-American church in Nashville, Tennessee. Results Thirty-four participants (aged 56.1 ± 11 years, body mass index (BMI) 36.7 ± 6.6 kg/m2) completed the intervention. Lifestyle changes after the 12 weekly sessions showed some positive trends including reduced sodium intake (from 2725.3 ± 326.5 to 2132 ± 330, mg/day, P = 0.008), increased walking steps (from 4392.1 ± 497.2 to 4895.3 ± 497.9, steps/day, not significant), and slightly decreased Perceived Stress Scale (PSS) scores (from 13.7 ± 1.4 to 12.4 ± 1.5, not significant). Body fat % among male participants decreased significantly (from 33.8 ± 2.6 to 28 ± 2.6, %, P = 0.043). Among cardiometabolic risk biomarkers, hemoglobin A1c (HbA1c) decreased significantly (from 6.6 ± 0.2 to 6.1 ± 0.2, %, P < 0.001). The baseline PSS score was positively associated with baseline adiposity levels (e.g., weight, β = 2.4, P = 0.006). Twenty-one participants took part in focus groups during the program to identify barriers to healthy lifestyle changes. Primary barriers reported were price, time for preparing healthy meals, unfamiliarity with mindfulness activities, their health condition, and daily schedule available for physical activities. Conclusions This church-based pilot intervention was proven feasible by showing modest progress in reducing adiposity and decreasing HbA1c levels. The focus group and interactive methods facilitated program direction. Future full-scale studies are warranted to identify key strategies that provide more personalized approaches and supportive environments to sustain a healthy lifestyle among these at risk minorities with limited resources.

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
Background Human papillomavirus (HPV) infection has been causally linked to six cancers, and many disproportionately affect minorties. This study reports on the development and effectiveness of an intervention aimed at increasing HPV vaccine uptake among African American and Hispanic pediatric patients in safety-net clinics. Methods Formative research, community engagement, and theory guided development of the intervention. A clustered, non-randomized controlled pragmatic trial was conducted in four clinics providing healthcare for the underserved in Tennessee, U.S., with two intervention sites and two usual care sites. Patients aged 9-18 years (N = 408) and their mothers (N = 305) enrolled, with children clustered within families. The intervention consisted of two provider/staff training sessions and provision of patient education materials, consisting of a video/flyer promoting HPV vaccine. Medical records were reviewed before/after the initial visit and after 12 months. Results At the initial visit, provision of patient education materials and provider recommendation were higher at intervention sites versus usual care sites, and receipt of HPV vaccine was higher at intervention sites (45.4% versus 32.9%) but not significantly after adjusting for patient’s age and mother’s education. Provider recommendation, but not education materials, increased the likelihood of vaccine receipt at the initial visit, although over one-third of intervention mothers cited the flyer/video as motivating vaccination. Completion of the 3-dose series at follow-up was lower in the intervention arm. Conclusions Future interventions should combine patient education, intensive provider/staff education, and patient reminders. Research should compare patient education focusing on HPV vaccine only versus all adolescent vaccines. Trial registration Retrospectively registered with ClinicalTrials.gov NCT02808832, 9/12/16 Electronic supplementary material The online version of this article (doi:10.1186/s12889-017-4094-1) contains supplementary material, which is available to authorized users.

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 The role of dietary lycopene in chronic disease prevention is not well known. METHODS This study examined intake of lycopene and other antioxidants from lycopene-rich foods (e.g., pizza and pasta) simultaneously with plasma levels of lycopene and other antioxidants in a representative cross-sectional sample (187 Blacks, 182 Whites, 40-79 years old) from the Southern Community Cohort Study (SCCS). The SCCS is an ongoing study conducted in populations at high risk for chronic diseases living in Southeastern United States. Dietary intake was assessed using a validated food frequency questionnaire (FFQ), and plasma levels of lycopene and other antioxidants were measured at baseline (2002-2005). The participants were classified into tertiles according to consumption of pizza and pasta food groups. RESULTS Lycopene dietary intake and plasma lycopene concentrations were significantly higher in the highest (tertile 3) compared to tertiles 1 and 2 (both P < 0.01). Total energy intake ranged from 1964.3 ± 117.1 kcal/day (tertile 1) to 3277.7 ± 115.8 kcal/day (tertile 3) (P<0.0001). After adjusting for age and energy intake, total dietary fat, saturated fatty acids, trans-fatty acids, and sodium intakes were significantly higher in tertile 3 than tertiles 2 and 1 (all P <0.01). Vitamin C intake was significantly lower in tertile 3 than tertiles 1 and 2 (P = 0.003). Except for γ-tocopherol being higher in tertile 3 than tertiles 1 and 2 (P = 0.015), the plasma concentrations of antioxidants were lower in tertile 3 than tertiles 1 and 2 (β-carotene, α-carotene, lutein and zeaxanthin, all P<0.05). CONCLUSIONS In the SCCS population, pizza and pasta were the main sources of dietary lycopene and their intake was associated with plasma lycopene concentration. Diets with frequent pizza and pasta consumption were high in energy, saturated fatty acids, trans-fatty acids, sodium and low in other antioxidants. Future studies of lycopene as a protective dietary factor against chronic disease should consider the overall nutritional quality of lycopene-containing foods.

Abstract
Church interventions can reduce obesity disparities by empowering participants with knowledge and skills within an established community. The purpose of this study was to evaluate the Biomedical/Obesity Reduction Trial (BMORe) and investigate changes in health beliefs among obese adult participants. Ten pre-/post-intervention focus groups applying the Health Belief Model conducted in two African-American churches in Tennessee (n = 20) and South Carolina (n = 20), and one rural Appalachian church in Kentucky (n = 21). Two independent coders using NVivo analyzed transcribed audio data and notes. Participants' health status of being overweight/obese and having comorbidities of diabetes and high blood pressure motivated enrollment in BMORe. Initially participants voiced low self-efficacy in cooking healthy and reading food labels. BMORe made participants feel "empowered" after 12 weeks compared to initially feeling "out of control" with their weight. Participants reported improvements in emotional health, quality of life, and fewer medications. During post-intervention focus groups, participants reported increased self-efficacy through family support, sharing healthy eating strategies, and having accountability partners. Solidarity and common understanding among BMORe participants led focus group attendees to comment how their peers motivated them to stay in the program for 12 weeks. Long-term barriers include keeping the weight off by maintaining habits of exercise and healthy eating. Implementation of pre-/post-intervention focus groups is an innovative approach to evaluate an obesity intervention and track how changes in health beliefs facilitated behavior change. This novel approach shows promise for behavioral interventions that rely on participant engagement for sustained effectiveness.

Abstract
BACKGROUND The American Cancer Society (ACS) publishes behavioral guidelines for cancer prevention, including standards on body weight, physical activity, nutrition, alcohol, and tobacco use. The impact of these guidelines has been rarely studied in low-income and African American populations. METHODS The study included 61,098 racially diverse, mainly low-income adults who participated in the Southern Community Cohort Study and were followed for a median of 6 years. Cox models were used to estimate HRs for cancer incidence associated with behaviors and with an ACS physical activity/nutrition 0-to-4 compliance score indicating the number of body weight, physical activity, healthy eating, and alcohol guidelines met. RESULTS During the study period, 2,240 incident cancers were identified. Significantly lower cancer incidence was found among never smokers and non/moderate alcohol drinkers, but not among those meeting guidelines for obesity, physical activity, and diet. The ACS compliance score was inversely associated with cancer risk among the 25,509 participants without baseline chronic disease. HRs for cancer incidence among those without baseline chronic diseases and who met one, two, three, or four guidelines versus zero guidelines were 0.93 (95% confidence intervals, 0.71-1.21), 0.85 (0.65-1.12), 0.70 (0.51-0.97), and 0.55 (0.31-0.99), respectively. Associations were consistent in analyses stratified by sex, race, household income, and smoking status. CONCLUSIONS Meeting the ACS smoking and body weight/physical activity/dietary/alcohol guidelines for cancer prevention is associated with reductions in cancer incidence in low-income and African American populations. IMPACT This study provides strong evidence supporting lifestyle modification to lower cancer incidence in these underserved populations. Cancer Epidemiol Biomarkers Prev; 25(5); 846-53. ©2016 AACR.

Abstract
Abstract
Introduction: Adverse childhood experiences (ACE) have been implicated in several adult chronic diseases. ACE may also be associated with reproductive and lifestyle factors and biomarkers associated with breast cancer overall, and with estrogen receptor negative (ER-) disease specifically.
Methods: We examined whether self-reported ACE (verbal, physical, or sexual abuse; household mental illness or substance abuse; domestic violence, parental separation/divorce, and incarcerated household members) was associated with several reproductive and lifestyle breast cancer risk factors including age at menarche and age at first birth, and four biomarkers: adiponectin, C-peptide, high sensitivity C-reactive protein (hsCRP), and insulin-like growth factor-1 (IGF-1). The study population included 16,062 black and white women in the Southern Community Cohort Study. We grouped women into three categories: 0 experiences, 1-2 experiences and 3-10 experiences (high). Cross-sectional associations were analysed using logistic or linear regression.
Results: Women with high ACE were more likely to have: menarche before age 12, ever breastfed, more than two births, first birth before age 18, initiated smoking before age 16, and be current smokers compared to those with no ACE. Parous women with high ACE were 54% more likely to have ever breastfed (OR: 1.54, 95% CI: 1.39, 1.70; p-trend <0.0001) and 65% more likely to have first given birth before age 18 (OR: 1.65, 95% CI: 1.48, 1.85; p-trend <0.0001). ACE was not associated with body mass index (BMI) at enrollment, BMI at age 21, adiponectin, C-peptide or hsCRP levels. ACE was inversely associated with IGF-1. Women with high ACE had mean IGF-1 levels of 104.3 ng/ml compared to 119.2 ng/ml among women with no ACE (p-trend=0.007). Results generally did not differ between Blacks and Whites.
Conclusions: Our findings suggest that ACE is associated with reproductive patterns that have been shown to increase risk of ER- breast cancer. Future work should examine associations between ACE and breast cancer risk according to ER status.

Abstract
OBJECTIVES Adverse childhood experiences (ACE) can affect health in adulthood. We investigate the relationship between childhood experiences and adult cancer risk and screening behaviors in a racially diverse, low income population. METHODS Nearly 22,000 adults 40 years and older in the Southern Community Cohort Study were administered the ACE questionnaire. We estimated odds ratios (OR) for the prevalence of smoking, alcohol consumption, BMI and five cancer screening methods in relation to the ACE score. RESULTS Over half reported at least one ACE, with percentages higher for women (61%) than men (53%). Higher ACE scores were related to increased prevalence of smoking (ORs 1.25 (1.05-1.50) to 2.33 (1.96-2.77). Little association was seen between rising ACE score and alcohol consumption or BMI, except for a modest trend in morbid obesity (BMI ≥ 40 kg/m2). Mammography and cervical cancer screening decreased with rising ACE scores, but no trends were seen with prostate or colorectal cancer screening. CONCLUSIONS Adverse childhood experiences are strong predictors of adult cancer risk behaviors, particularly increased likelihood of smoking, and among women, lower mammography and Pap screening rates.

Abstract
Abstract
Purpose: Lycopene is regarded as a promising antioxidant, potentially protective against chronic diseases such as certain cancers. Unlike other antioxidant nutrients, lycopene mostly comes from tomato based processed foods, rather than from fresh vegetables and fruits. Herein we examine whether foods rich in lycopene offer a full spectrum of antioxidant nutrients needed for chronic disease prevention.
Methods: Serum levels of lycopene and other antioxidant nutrients were measured in a representative cross-sectional sample of low-income Blacks (n=189) and Whites (n=183) age 40-79 years participating in the Southern Community Cohort Study (SCCS). Dietary intakes of lycopene, other nutrients, and individual foods were ascertained via a food frequency questionnaire (FFQ).
Results: Pizza and pasta showed the strongest correlation with dietary lycopene (adjusted for age and total calories, R spearman = 0.54, P<0.0001), and were the only food sources significantly correlated with serum lycopene (adjusted for age and LDL-cholesterol, R spearman = 0.14, P=0.007). Across pizza and pasta consumption tertiles, estimated dietary lycopene intake increased from 4147±305 to 4983±287 to 8208±301 mcg (P<.0001) per day while serum lycopene concentrations were 27.8±1.3, 32.7±1.3 and 32.0±1.2 mcg (P=.01). There were no significant differences in key socio-demographic and lifestyle variables, except for slightly younger age in the highest tertile. Total caloric intake increased substantially with tertiles of consumption of pizza and pasta, rising from 1965±18 to 2294±114 to 3242±114 kcal (P<.0001). Adjusted for age and total calories, the consumption of protein, saturated fat, and trans fat were increased significantly at tertile 3 compared to tertile 1 and tertile 2 (e.g., saturated fat rose from 27.5±0.7 to 27.9±0.7 to 32.1±0.7 g, P<.0001), whereas fiber and sugar intake levels did not differ significantly across the tertiles. For micronutrients, the sodium and sodium to potassium ratio were much higher in tertile 3 than those in tertile 1 and tertile 2 (e.g., sodium tertile levels were 4179±90, 4095±85, 4635±89 mg, P<.0001). The majority of other antioxidant nutrients' intake levels, however, did not vary across tertiles, or even decreased significantly with higher intake of pizza and pasta (e.g., folate declined from 310.3±8.3 to 302.6±7.8 to 270.8±8.2 mcg, P=.003). Similarly, serum concentrations of other major antioxidants either did not change significantly or even decreased across tertiles of pizza and pasta (e.g., serum concentrations of carotene declined from 16.8±1.4 to 12.8±1.4 to 10.3±1.4 µg/dl, P=.0005).
Conclusion: In the current study, pizza and pasta were shown to be the main contributors to dietary lycopene and predictive of serum lycopene levels. Pizza and pasta as consumed by the SCCS participants, however, may offer less antioxidation protection than expected based on their lycopene content alone, since such meals provide higher calories, more unhealthy fat and less overall antioxidants.

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
IMPORTANCE High intake of nuts has been linked to a reduced risk of mortality. Previous studies, however, were primarily conducted among people of European descent, particularly those of high socioeconomic status. OBJECTIVE To examine the association of nut consumption with total and cause-specific mortality in Americans of African and European descent who were predominantly of low socioeconomic status (SES) and in Chinese individuals in Shanghai, China. DESIGN, SETTING, AND PARTICIPANTS Three large cohorts were evaluated in the study. One included 71 764 US residents of African and European descent, primarily of low SES, who were participants in the Southern Community Cohort Study (SCCS) in the southeastern United States (March 2002 to September 2009), and the other 2 cohorts included 134 265 participants in the Shanghai Women's Health Study (SWHS) (December 1996 to May 2000) and the Shanghai Men's Health Study (SMHS) (January 2002 to September 2006) in Shanghai, China. Self-reported nut consumption in the SCCS (approximately 50% were peanuts) and peanut-only consumption in the SMHS/SWHS were assessed using validated food frequency questionnaires. MAIN OUTCOMES AND MEASURES Deaths were ascertained through linkage with the National Death Index and Social Security Administration mortality files in the SCCS and annual linkage with the Shanghai Vital Statistics Registry and by biennial home visits in the SWHS/SMHS. Cox proportional hazards regression models were used to calculate hazard ratios (HRs) and 95% CIs. RESULTS With a median follow-up of 5.4 years in the SCCS, 6.5 years in the SMHS, and 12.2 years in the SWHS, 14,440 deaths were identified. More than half of the women in the SCCS were ever smokers compared with only 2.8% in the SWHS. The ever-smoking rate for men was 77.1% in the SCCS and 69.6% in the SMHS. Nut intake was inversely associated with risk of total mortality in all 3 cohorts (all P<.001 for trend), with adjusted HRs associated with the highest vs lowest quintiles of intake being 0.79 (95% CI, 0.73-0.86) and 0.83 (95% CI, 0.77-0.88), respectively, for the US and Shanghai cohorts. This inverse association was predominantly driven by cardiovascular disease mortality (P<.05 for trend in the US cohort; P<.001 for trend in the Shanghai cohorts). When specific types of cardiovascular disease were examined, a significant inverse association was consistently seen for ischemic heart disease in all ethnic groups (HR, 0.62; 95% CI, 0.45-0.85 in blacks; HR, 0.60; 95% CI, 0.39-0.92 in whites; and HR, 0.70; 95% CI, 0.54-0.89 in Asians for the highest vs lowest quintile of nut intake). The associations for ischemic stroke (HR, 0.77; 95% CI, 0.60-1.00 for the highest vs lowest quintile of nut intake) and hemorrhagic stroke (HR, 0.77; 95% CI, 0.60-0.99 for the highest vs lowest quintile of nut intake) were significant only in Asians. The nut-mortality association was similar for men and women and for blacks, whites, and Asians and was not modified by the presence of metabolic conditions at study enrollment. CONCLUSIONS AND RELEVANCE Nut consumption was associated with decreased overall and cardiovascular disease mortality across different ethnic groups and among individuals from low SES groups. Consumption of nuts, particularly peanuts given their general affordability, may be considered a cost-effective measure to improve cardiovascular health.

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
OBJECTIVES We evaluated the independent and joint effects of race, individual socioeconomic status (SES), and neighborhood SES on mortality risk. METHODS We conducted a prospective analysis involving 52 965 non-Hispanic Black and 23 592 non-Hispanic White adults taking part in the Southern Community Cohort Study. Cox proportional hazards modeling was used to determine associations of race and SES with all-cause and cause-specific mortality. RESULTS In our cohort, wherein Blacks and Whites had similar individual SES, Blacks were less likely than Whites to die during the follow-up period (hazard ratio [HR] = 0.78; 95% confidence interval [CI] = 0.73, 0.84). Low household income was a strong predictor of all-cause mortality among both Blacks and Whites (HR = 1.76; 95% CI = 1.45, 2.12). Being in the lowest (vs highest) category with respect to both individual and neighborhood SES was associated with a nearly 3-fold increase in all-cause mortality risk (HR = 2.76; 95% CI = 1.99, 3.84). There was no significant mortality-related interaction between individual SES and neighborhood SES among either Blacks or Whites. CONCLUSIONS SES is a strong predictor of premature mortality, and the independent associations of individual SES and neighborhood SES with mortality risk are similar for Blacks and Whites.

Abstract
Abstract
Lung cancer is the leading cause of cancer deaths in the United States and many other countries. Cumulative evidence suggests that chronic inflammation may play an etiologic role in lung carcinogenesis. C-reactive protein (CRP), a circulating biomarker of systemic inflammation, has been associated with increased lung cancer risk in several retrospective and a few prospective studies. However, prior studies included only a small number of African Americans with lung cancer, a group with higher lung cancer incidence rates than other ethnic or racial groups. We conducted a nested case-control study to evaluate the association of pre-diagnostic circulating levels of CRP with subsequent risk of lung cancer using data and biological samples collected in the Southern Community Cohort Study (SCCS), a prospective cohort study, in which approximately 86,000 men and women aged 40-79 years, two-thirds of whom are African American, were recruited from 2002 to 2009. Plasma CRP levels in 396 incident lung cancer cases (258 African Americans and 130 Whites) were compared with 784 matched controls. Overall, baseline plasma CRP levels were 29.4% higher among participants who subsequently developed lung cancer than among those who remained free of the disease (geometric mean: 4.4 µg/ml vs. 3.4 µg/ml; P = 0.0015). This difference was seen primarily among African Americans (geometric mean: 4.1 µg/ml vs. 3.0 µg/ml; P=0.0026) and not among Whites (geometric mean: 5.0 µg/ml vs. 4.5 µg/ml; P=0.3613). In both African Americans and Whites, elevated risk of lung cancer was associated with high circulating levels of CRP. However, the association was only statistically significant among African Americans; adjusted odds ratios (ORs) for developing lung cancer increased from 1.0 to 1.46 (95%CI: 0.89-2.40); 1.52 (95%CI: 0.88-2.61), and 2.95 (95%CI: 1.77-4.93) with increasing quartiles of plasma CRP (P-trend = 0.0018). The findings from this study suggest that circulating CRP level is positively associated with prospective lung cancer risk among African Americans.

Mammography use among women with and without diabetes: results from the Southern Community Cohort Study. J Epidemiol Glob Health 2014; 4:223-30. [PMID: 25107658 PMCID: PMC4129367 DOI: 10.1016/j.jegh.2014.03.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2014] [Revised: 02/25/2014] [Accepted: 03/16/2014] [Indexed: 12/29/2022] Open
Abstract
Studies have shown an increased risk of breast cancer associated with diabetes which may be due to differences in mammography use among women who have diabetes compared with women who do not have diabetes. Baseline data was used from the Southern Community Cohort Study - a prospective cohort study conducted primarily among low-income persons in the southeastern United States - to examine the association between diabetes and mammography use. In-person interviews collected information on diabetes and mammography use from 14,665 white and 30,846 black women aged 40-79years between 2002 and 2009. After adjustment for potential confounding, white women with diabetes were no more likely (odds ratio [OR] 0.95, 95% confidence interval [CI] 0.85-1.06) to undergo mammography within the past 12months than white women without diabetes. Nor was there an association between diabetes and mammography use among black women (OR 1.00, 95% CI 0.93-1.07). An increase in mammography use was seen within one year following diabetes diagnosis, more so among white than black women, but this was offset by decreases thereafter. Although there was some evidence of an increase in mammography use within one year of diabetes diagnosis, these results suggest that mammography use is not related to diabetes.

Abstract
There is limited evidence demonstrating the benefits of physical activity with regard to mortality risk or the harms associated with sedentary behavior in black adults, so we examined the relationships between these health behaviors and cause-specific mortality in a prospective study that had a large proportion of black adults. Participants (40-79 years of age) enrolled in the Southern Community Cohort Study between 2002 and 2009 (n = 63,308) were prospectively followed over 6.4 years, and 3,613 and 1,394 deaths occurred in blacks and whites, respectively. Black adults who reported the highest overall physical activity level (≥32.3 metabolic equivalent-hours/day vs. <9.7 metabolic equivalent-hours/day) had lower risks of death from all causes (hazard ratio (HR) = 0.76. 95% confidence interval (CI): 0.69, 0.85), cardiovascular disease (HR = 0.81, 95% CI: 0.67, 0.98), and cancer (HR = 0.76, 95% CI: 0.62, 0.94). In whites, a higher physical activity level was associated with a lower risk of death from all causes (HR = 0.76, 95% CI: 0.64, 0.90) and cardiovascular disease (HR = 0.69, 95% CI: 0.49, 0.99) but not cancer (HR = 0.95, 95% CI: 0.67, 1.34). Spending more time being sedentary (>12 hours/day vs. <5.76 hours/day) was associated with a 20%-25% increased risk of all-cause mortality in blacks and whites. Blacks who reported the most time spent being sedentary (≥10.5 hours/day) and lowest level of physical activity (<12.6 metabolic equivalent-hours/day) had a greater risk of death (HR = 1.47, 95% CI: 1.25, 1.71). Our study provides evidence that suggests that health promotion efforts to increase physical activity level and decrease sedentary time could help reduce mortality risk in black adults.

Spending more time being sedentary (>12 hours/day vs. <5.76 hours/day) was associated with a 20%-25% increased risk of all-cause mortality in blacks and whites. Blacks who reported the most time spent being sedentary (≥10.5 hours/day) and lowest level of physical activity (<12.6 metabolic equivalent-hours/day) had a greater risk of death (HR = 1.47, 95% CI: 1.25, 1.71). Our study provides evidence that suggests that health promotion efforts to increase physical activity level and decrease sedentary time could help reduce mortality risk in black adults.

Abstract
There is limited evidence demonstrating the benefits of physical activity with regard to mortality risk or the harms associated with sedentary behavior in black adults, so we examined the relationships between these health behaviors and cause-specific mortality in a prospective study that had a large proportion of black adults. Participants (40-79 years of age) enrolled in the Southern Community Cohort Study between 2002 and 2009 (n = 63,308) were prospectively followed over 6.4 years, and 3,613 and 1,394 deaths occurred in blacks and whites, respectively. Black adults who reported the highest overall physical activity level (≥32.3 metabolic equivalent-hours/day vs. <9.7 metabolic equivalent-hours/day) had lower risks of death from all causes (hazard ratio (HR) = 0.76. 95% confidence interval (CI): 0.69, 0.85), cardiovascular disease (HR = 0.81, 95% CI: 0.67, 0.98), and cancer (HR = 0.76, 95% CI: 0.62, 0.94).

Abstract
There is limited evidence demonstrating the benefits of physical activity with regard to mortality risk or the harms associated with sedentary behavior in black adults, so we examined the relationships between these health behaviors and cause-specific mortality in a prospective study that had a large proportion of black adults. Participants (40-79 years of age) enrolled in the Southern Community Cohort Study between 2002 and 2009 (n = 63,308) were prospectively followed over 6.4 years, and 3,613 and 1,394 deaths occurred in blacks and whites, respectively. Black adults who reported the highest overall physical activity level (≥32.3 metabolic equivalent-hours/day vs. <9.7 metabolic equivalent-hours/day) had lower risks of death from all causes (hazard ratio (HR) = 0.76. 95% confidence interval (CI): 0.69, 0.85), cardiovascular disease (HR = 0.81, 95% CI: 0.67, 0.98), and cancer (HR = 0.76, 95% CI: 0.62, 0.94). In whites, a higher physical activity level was associated with a lower risk of death from all causes (HR = 0.76, 95% CI: 0.64, 0.90) and cardiovascular disease (HR = 0.69, 95% CI: 0.49, 0.99) but not cancer (HR = 0.95, 95% CI: 0.67, 1.34). Spending more time being sedentary (>12 hours/day vs. <5.76 hours/day) was associated with a 20%-25% increased risk of all-cause mortality in blacks and whites. Blacks who reported the most time spent being sedentary (≥10.5 hours/day) and lowest level of physical activity (<12.6 metabolic equivalent-hours/day) had a greater risk of death (HR = 1.47, 95% CI: 1.25, 1.71). Our study provides evidence that suggests that health promotion efforts to increase physical activity level and decrease sedentary time could help reduce mortality risk in black adults.
