Harvest for health in survivors of chronic disease: A demonstration project in the Alabama Black Belt and Mississippi Delta Region.

This demonstration project expands upon the Harvest for Health vegetable gardening intervention for cancer survivors by: (i) including survivors of other chronic diseases (i.e. heart disease and diabetes); and (ii) targeting an area with known health inequities (Alabama Black Belt and Mississippi Delta Region). To assess: (i) gardening acceptability (engagement, satisfaction, sustainability, and safety); and (ii) changes over time in health behaviors (fruit and vegetable [F&V] intake, and physical activity) and outcomes (physical performance and anthropometrics). Chronic disease survivors (CDS) were recruited across 15 counties in Alabama and Mississippi and provided with gardening supplies and paired with a master gardener (MG). MGs mentored participants in planning, planting, and maintaining a vegetable garden over a 3-month period. Data collection consisted of an electronic survey (baseline, post-intervention, 6-month follow-up) and community-based physical assessments (baseline and post-intervention). Participants (n = 137; 92% African American; Mage = 65) included individuals with a history of diabetes (56%), heart disease (29%), and cancer (26%). Seventy-five percent of participants engaged in gardening ≥3 times a week. Significant improvements in F&V intake (+0.73, P = .04), physical activity (+49.6, P < .01), and 4 of 7 physical performance measures were observed, while positive trends were seen in others. Eighteen participants withdrew (13% attrition rate). No adverse events occurred. Participants were satisfied with their gardening experience (90%) and were still gardening at 6-month follow-up (85%). Seventy-two percent of participants expanded, or planned on expanding, their garden at 6-month follow-up. Harvest for Health was acceptable and associated with improved health behaviors and outcomes.

In the Alabama Black Belt and Mississippi Delta region of the USA, incidence and mortality rates of high-burden chronic diseases (cancer, cardiovascular disease, and diabetes) are among the highest in the nation. Behavioral risk factors associated with chronic disease include low fruit and vegetable intake and physical inactivity. Vegetable gardening is a holistic approach to improving these health behaviors. Harvest for Health, a mentored home-based vegetable gardening intervention, pairs cancer survivors with master gardener (MG) mentors to guide survivors in planning, planting, and maintaining a vegetable garden. The current demonstration project expands upon Harvest for Health by: (i) including survivors of cardiovascular disease and diabetes (in addition to cancer); and (ii) targeting an area with known health inequities (Alabama Black Belt and Mississippi Delta). One hundred thirty-seven chronic disease survivors (CDS) enrolled in the 3-month demonstration project. Participants were provided gardening supplies for a summer garden and MG mentorship over a 3-month period. Participants engaged in gardening several times a week, reported satisfaction with their gardening experience, and were still gardening at 6-month follow-up. Improvements among CDS were seen in health behaviors (fruit and vegetable intake and physical activity) and physical well-being (physical function battery and weight).

Impact of Affordable Care Act provisions on the racial makeup of patients enrolled at a Deep South, high-risk breast cancer clinic.

Purpose: Black women are less likely to receive screening mammograms and are at a higher lifetime risk for developing breast cancer compared to their White counterparts. Affordable Care Act (ACA) provisions decreased cost sharing for women's preventive screening, potentially mitigating screening disparities. We examined enrollment of a high-risk screening program before and after ACA implementation stratified by race. Methods: This retrospective, quasi-experimental study examined the ACA's impact on patient demographics at a high-risk breast cancer screening clinic from 02/28/2003-02/28/2019. Patient demographic data were abstracted from electronic medical records and descriptively compared in the pre- and post-ACA time periods. Interrupted time series (ITS) analysis using Poisson regression assessed yearly clinic enrollment rates by race using incidence rate ratios (IRR) and 95% confidence intervals (CI). Results: 2,767 patients enrolled in the clinic. On average, patients were 46 years old (SD, ± 12), 82% were commercially insured, and 8% lived in a highly disadvantaged neighborhood. In ITS models accounting for trends over time, Prior to ACA implementation, White patient enrollment was stable (IRR 1.01, 95% CI 1.00-1.02) while Black patient enrollment increased at 13% per year (IRR 1.13, 95% CI 1.05-1.22). Compared to the pre-ACA enrollment period, the post-ACA enrollment rate remained unchanged for White patients (IRR 0.99, 95% CI 0.97-1.01) but decreased by 17% for Black patients (IRR 0.83, 95% CI 0.74-0.92). Conclusion: Black patient enrollment decreased at a high-risk breast cancer screening clinic post-ACA compared to the pre-ACA period, indicating a need to identify factors contributing to racial disparities in clinic enrollment.

Concept Mapping with Black Men: Barriers to Prostate Cancer Screening and Solutions.

A structured participatory approach of group concept mapping (GCM) was used to understand barriers and concerns around prostate cancer screening (PCS) among African American (AA) men. One-hundred thirteen AA men aged 35-70 years enrolled from one urban and three rural counties in Alabama. Eighty-five men brainstormed and generated 41 unique ideas in response to a single prompt. Participants (n = 70) sorted ideas into groups and rated them in terms of importance and feasibility to change opinions. Multi-dimensional scaling and cluster analysis were used to analyze the data. Participants (n=50) discussed visual concept maps during three focus-groups and recommended solutions to address key barriers. The mean age of respondents was 52 (±10), 50% were rural, 37% were college-educated, 56% with income <$44,500, and 22% with PROCASE Knowledge Index ≤5. Cluster analyses revealed eight clusters. Participants ranked barriers grouped under "fear of consequences of test," "lack of knowledge," and "costs/no insurance" as most important to improve PCS among AA men. The same three clusters along with "dislike for digital rectal exam (DRE)" were ranked as most difficult to change. No major differences were noted by urban/rural status. Solutions to address barriers included education at a younger age, alternate testing options and open discussion about DRE, and clear and precise messaging by peers and relatable role models. Our study identified specific barriers to PCS among AA with diverse sociodemographic backgrounds. Culturally sensitive interventions delivered by trained healthcare professionals, peers, and relatable role models, can potentially increase PCS among AA men.

Training and Dissemination of Lung Cancer Education Curriculum Among Community Health Advisors in the Deep South: a Program Evaluation.

Lung cancer is the leading cause of cancer mortality in the USA. In the rural Black Belt region of Alabama, high rates of lung cancer incidence and mortality coupled with disproportionate lack of access to health services stresses the need for navigating high risk and disproportionately affected groups towards successfully obtaining lung cancer screenings. We utilized our well-accepted Community Health Advisor (CHA) model for education and awareness. This study seeks to evaluate the results of the Alabama Lung Cancer Awareness, Screening, and Education (ALCASE) training on CHAs, program evaluation, and lessons learned. A total of 202 participants were eligible and enrolled for CHA training. One hundred thirty CHAs were included for the final analyses. Descriptive statistics were computed; differences in pre-test and post-test scores were compared across demographic characteristics of the participants using paired t-test/one-way ANOVA. Of the 130 CHAs, 46% were 65 years or older; 98% were African Americans, and 87% were female; 17% of participants were cancer survivors. The mean post-test scores were 2.2 points greater than mean pre-test scores, and the difference was significant (mean (SD): pre-test = 20.8 (2.8) versus post-test = 23 (2.2); p = 0.001). No notable difference in pre-test and post-test scores were observed by CHA's demographic characteristics except by their county of residence or work (p = 0.0019). We demonstrate the capability and value of successfully recruiting and training motivated community members to be able to serve educators to better reach medically underserved and historically excluded communities.

1,3-Butadiene, styrene and selected outcomes among synthetic rubber polymer workers: Updated exposure-response analyses.

OBJECTIVE: - To evaluate exposure-response relationships between 1,3-butadiene and styrene and selected diseases among synthetic rubber polymer workers. METHODS: - 21,087 workers (16,579 men; 4508 women) were followed from 1943 through 2009 to determine mortality outcomes. Cox regression models estimated rate ratios (RRs) and 95% confidence intervals (CIs) by quartile of cumulative exposure to butadiene or styrene and exposure-response trends for cancers of the bladder, lung, kidney, esophagus and pancreas, and for all nonmalignant respiratory disease (NMRD), chronic obstructive pulmonary disease (COPD) and pneumonia. RESULTS: - Bladder cancer RRs were 2.13 (95% CI = 1.03 to 4.41) and 1.64 (95% CI = 0.76 to 3.54) in the highest quartiles of cumulative exposure to butadiene and styrene, respectively, and exposure-response trends were positive for both monomers (butadiene, trend p = 0.001; styrene, trend p = 0.004). Further analyses indicated that the exposure-response effect of each monomer on bladder cancer was demonstrated clearly only in the subgroup with high cumulative exposure (at or above the median) to the other monomer. Lung cancer was not associated with either monomer among men. Among women, lung cancer RRs were above 1.0 in each quartile of cumulative exposure to each monomer, but exposure-response was not seen for either monomer. Male workers had COPD RRs slightly above 1.0 in each quartile of cumulative exposure to each monomer, but there was no evidence of exposure-response among the exposed. Monomer exposure was not consistently associated with COPD in women or with the other cancer outcomes. CONCLUSIONS: - This study found a positive exposure-response relationship between monomer exposures and bladder cancer. The independent effects of butadiene and styrene on this cancer could not be delineated. In some analyses, monomer exposure was associated with lung cancer in women and with COPD in men, but inconsistent exposure-response trends and divergent results by sex do not support a causal interpretation of the isolated positive associations.

1,3-Butadiene, styrene and lymphohaematopoietic cancers among North American synthetic rubber polymer workers: exposure-response analyses.

OBJECTIVE: To evaluate exposure-response between 1,3-butadiene, styrene and lymphohaematopoietic cancers in an updated cohort of workers at six North American plants that made synthetic rubber polymers. METHODS: Employees were followed from 1943 through 2009 to determine mortality outcomes. Cox regression analyses estimated rate ratios (RRs) and 95% CIs by quartile of cumulative exposure to butadiene or styrene, measured in parts per million-years (ppm-years), and exposure-response trends for all leukaemia, lymphoid leukaemia, myeloid leukaemia, acute myeloid leukaemia, non-Hodgkin's lymphoma (NHL), multiple myeloma and all B-cell malignancies. RESULTS: Among 21 087 workers, adjusted RRs for butadiene and all leukaemia (132 deaths) rose with increasing exposure, with an RR of 2.53 (95% CI 1.37 to 4.67) in the highest exposure quartile (≥363.64 ppm-years), and the exposure-response trend was statistically significant for all leukaemia (p=0.014) and for lymphoid leukaemia (52 deaths, p=0.007). Styrene exposure-response trends for all leukaemia and lymphoid leukaemia were less consistent than those for butadiene. Cumulative exposures to butadiene and styrene were not associated consistently with myeloid leukaemias or the B-cell malignancies, NHL and multiple myeloma. CONCLUSIONS: We confirmed a positive exposure-response relationship between butadiene and all leukaemia among workers, most of whom had coexposure to styrene. Results supported an association between butadiene and lymphoid leukaemia, but not myeloid leukaemia, and provided little evidence of any association of butadiene or styrene exposures with major subtypes of B-cell malignancies other than lymphoid leukaemia, including NHL and multiple myeloma.

Mortality Among Men and Women in the North American Synthetic Rubber Industry, 1943 to 2009.

OBJECTIVE: To evaluate 1943 to 2009 mortality among 22,785 synthetic rubber industry employees. METHODS: Standardized mortality ratio (SMR) and internal Cox regression analyses. RESULTS: Among hourly employees with more than or equal to 10 years worked and more than or equal to 20 years since hire, SMRs were elevated for leukemia (SMR = 139, 95% confidence interval [CI] = 106 to 179), non-Hodgkin lymphoma (NHL) (SMR = 136, CI = 102 to 177), bladder cancer (SMR = 148, CI = 110 to 195) and, for women only, lung cancer (SMR = 225, CI = 103 to 427). Butadiene and styrene exposure-response trends were positive for leukemia and bladder cancer but not for NHL or for lung cancer among women. CONCLUSIONS: Results support a causal relationship between butadiene and leukemia. Interpretation of results for lung cancer among women and for bladder cancer is uncertain because of inability to control for smoking and inadequate or inconsistent support from other studies for an association between butadiene or styrene and the latter cancers.

Post-Deepwater Horizon Oil Spill Exposure Patterns Among Children in Mobile County, Alabama.

OBJECTIVE: The aim of this study was to characterize environmental exposure from Deepwater Horizon oil spill among pre-K to fourth-grade children from six schools in Mobile County, Alabama. METHODS: A mail-in survey administered 11 months post-oil spill to children's parents/caregivers elicited information on exposure-related activities. Descriptive and multivariable analyses were performed. RESULTS: Overall, 180 children (coastal schools, 90; inland schools, 90) completed the survey. During the post-oil spill period, children in coastal schools were less likely to reduce their exposure-related activities, including fishing; eating and selling caught fish; visiting beaches; and parental participation in cleanup activities, than children in inland schools. Particularly, fishing and eating caught fish were significantly associated with the coastal group (odds ratio = 2.28; 95% confidence interval = 1.54 to 3.36). CONCLUSION: Proximity to the shoreline may serve as an indicator for potential exposure in oil spills among vulnerable populations including children.

Tasman Spirit oil spill in Pakistan: research response and lessons learned.

BACKGROUND: This article presents lessons learned from an investigation of the acute human health effects of the "Tasman Spirit" oil spill from a perspective of conducting rapid response investigations in developing countries. METHODS: We reviewed various steps in our investigation, other studies on oil spills in Pakistan and around the world, and reflected upon our discussions and interactions with various stakeholders. RESULTS: The article highlights the importance of applying a public health, legal, and ethical framework for conducting rapid response investigations, developing a pre-established funding mechanism, and addressing study design issues, exposure and outcome measurements, political issues, community engagement, and communication of results. CONCLUSION: There is need to develop ethical and legal framework and funding mechanism for conducting rapid response research in developing countries. A repository of study protocols, validated tools, and laboratory methods for exposure and outcome assessment would be greatly beneficial.
