A Randomized Trial of Choice Architecture and Mailed Colorectal Cancer Screening Outreach in a Community Health Setting

BACKGROUND & AIMS

Mailed outreach for colorectal cancer (CRC) screening increases uptake but it is unclear how to offer the choice of testing. We evaluated if the active choice between colonoscopy and fecal immunochemical test (FIT), or FIT alone, increased response compared with colonoscopy alone.

METHODS

This pragmatic, randomized, controlled trial at a community health center included patients between ages 50 and 74 who were not up to date with CRC screening. Patients were randomized 1:1:1 to the following: (1) colonoscopy only, (2) active choice of colonoscopy or FIT, or (3) FIT only. Patients received an outreach letter with instructions for testing (colonoscopy referral and/or an enclosed FIT kit), a reminder letter at 2 months, and another reminder at 3 to 5 months via text message or automated voice recording. The primary outcome was CRC screening completion within 6 months.

RESULTS

Among 738 patients in the final analysis, the mean age was 58.7 years (SD, 6.2 y); 48.6% were insured by Medicaid and 24.3% were insured by Medicare; and 71.7% were White, 16.9% were Black, and 7.3% were Hispanic/Latino. At 6 months, 5.6% (95% CI, 2.8-8.5) completed screening in the colonoscopy-only arm, 12.8% (95% CI, 8.6-17.0) in the active-choice arm, and 11.3% (95% CI, 7.4-15.3) in the FIT-only arm. Compared with colonoscopy only, there was a significant increase in screening in active choice (absolute difference, 7.1%; 95% CI, 2.0-12.2; P = .006) and FIT only (absolute difference, 5.7%; 95% CI, 0.8-10.6; P = .02).

CONCLUSIONS

Both choice of testing and FIT alone increased response and may align with patient preferences.

Racial Differences in Germline Genetic Testing Completion Among Males With Pancreatic, Breast, or Metastatic Prostate Cancers

BACKGROUND

Germline genetic testing is a vital component of guideline-recommended cancer care for males with pancreatic, breast, or metastatic prostate cancers. We sought to determine whether there were racial disparities in germline genetic testing completion in this population.

PATIENTS AND METHODS

This retrospective cohort study included non-Hispanic White and Black males with incident pancreatic, breast, or metastatic prostate cancers between January 1, 2019, and September 30, 2021. Two nationwide cohorts were examined: (1) commercially insured individuals in an administrative claims database, and (2) Veterans receiving care in the Veterans Health Administration. One-year germline genetic testing rates were estimated by using Kaplan-Meier methods. Cox proportional hazards regression was used to test the association between race and genetic testing completion. Causal mediation analyses were performed to investigate whether socioeconomic variables contributed to associations between race and germline testing.

RESULTS

Our cohort consisted of 7,894 males (5,142 commercially insured; 2,752 Veterans). One-year testing rates were 18.0% (95% CI, 16.8%-19.2%) in commercially insured individuals and 14.2% (95% CI, 11.5%-15.0%) in Veterans. Black race was associated with a lower hazard of testing among commercially insured individuals (adjusted hazard ratio [aHR], 0.73; 95% CI, 0.58-0.91; P=.005) but not among Veterans (aHR, 0.99; 95% CI, 0.75-1.32; P=.960). In commercially insured individuals, income (aHR, 0.90; 95% CI, 0.86-0.96) and net worth (aHR, 0.92; 95% CI, 0.86-0.98) mediated racial disparities, whereas education (aHR, 0.98; 95% CI, 0.94-1.01) did not.

CONCLUSIONS

Overall rates of guideline-recommended genetic testing are low in males with pancreatic, breast, or metastatic prostate cancers. Racial disparities in genetic testing among males exist in a commercially insured population, mediated by net worth and household income; these disparities are not seen in the equal-access Veterans Health Administration. Alleviating financial and access barriers may mitigate racial disparities in genetic testing.

Qualitative study of perceptions of factors contributing to success or failure among participants in a US weight loss trial of financial incentives and environmental change strategies

BACKGROUND

The use of financial incentives and environmental change strategies to encourage health behaviour change is increasingly prevalent. However, the experiences of participants in incentive interventions are not well characterised. Examination of participant perceptions of financial incentives and environmental strategies can offer insights about how these interventions are facilitating or failing to encourage behaviour change.

OBJECTIVE

This study aimed to learn how participants in a randomised trial that tested financial incentives and environmental interventions to support weight loss perceived factors contributing to their success or failure in the trial.

DESIGN

Qualitative study with one-time interviews of trial participants with high and low success in losing weight, supplemented by study records of incentive payments and weight loss.

PARTICIPANTS

24 trial participants (12 with substantial weight loss and 12 with no weight loss) stratified equally across the 4 trial arms (incentives, environmental strategies, combined and usual care) were interviewed.

ANALYTICAL APPROACH

Transcribed interviews were coded and interpreted using an iterative process. Explanation development was completed using an abductive approach.

RESULTS

Responses of trial participants who were very successful in losing weight differed in several ways from those who were not. Successful participants described more robust prior attempts at dietary and exercise modification, more active engagement with self-limitations, more substantial social support and a greater ability to routinise dietary and exercise changes than did participants who did not lose weight. Successful participants often stated that weight loss was its own reward, even without receiving incentives. Neither group could articulate the details of the incentive intervention or consistently differentiate incentives from study payments.

CONCLUSIONS

A number of factors distinguished successful from unsuccessful participants in this intervention. Participants who were successful tended to attribute their success to intrinsic motivation and prior experience. Making incentives more salient may make them more effective for participants with greater extrinsic motivation.

Trust in federal COVID-19 vaccine oversight and parents' willingness to vaccinate their children against COVID-19: a cross-sectional study

BACKGROUND

Over half of the youth population in the United States, aged 6 months to 17 years, have not received the Coronavirus Disease 2019 (COVID-19) vaccine. Given parents' central role in vaccinating their children, we examined associations between parents' trust of the federal oversight of COVID-19 vaccine safety and their willingness to vaccinate their children against COVID-19.

METHODS

This cross-sectional study included 975 parents of minor children residing in Philadelphia who completed the online survey between September 2021 and February 2022. Trust was measured using a four-point Likert scale ranging from 'do not trust' to 'fully trust' for two variables: (1) trust in federal oversight of COVID-19 vaccine safety for children and (2) trust in federal oversight of COVID-19 vaccine safety for the general public. A multiple logistic regression evaluated associations between trust and parents' willingness to vaccinate their children, which was measured on a five-point Likert scale ranging from 'strongly disagree' to 'strongly agree.' The analysis was adjusted for race/ethnicity, age, sexual orientation, gender, education, insurance, and parents' vaccination status.

RESULTS

Analyses included 975 parents whose children had not previously been vaccinated against COVID-19 (mean age 36.79, standard deviation 6.4; 42.1% racial/ethnic minorities; 93.2% heterosexual; and 73.7% with a college degree). Greater trust regarding federal oversight of COVID-19 vaccine safety for children [adjusted odds ratio (aOR) = 1.52, 95% confidence interval (CI): 1.13-2.04] and for the public (aOR = 1.58, 95% CI: 1.17-2.14) were each associated with increased willingness to have their child vaccinated against COVID-19. Unvaccinated parents had decreased willingness compared to parents who had received at least one dose of the vaccine (aOR = 0.14, 95% CI: 0.04-0.41). College-graduate parents exhibited increased willingness compared to those without a college degree (aOR = 2.07, 95% CI: 1.52-2.81). Non-heterosexual parents showed increased willingness compared to heterosexual parents (aOR = 2.30, 95% CI: 1.20-4.76).

CONCLUSIONS

Trust in federal COVID-19 vaccine oversight was associated with parental willingness to vaccinate their children against COVID-19 among parents whose children have not yet been vaccinated. Identifying and addressing causes of mistrust are crucial next steps to promote child vaccination. Intervention efforts to address trust gaps should remain a public health priority.

Association of the social disorganization index with time to first septic shock event in children with acute myeloid leukemia

BACKGROUND

Pediatric acute myeloid leukemia (AML) chemotherapy increases the risk of life-threatening complications, including septic shock (SS). An area-based measure of social determinants of health, the social disorganization index (SDI), was hypothesized to be associated with SS and SS-associated death (SS-death).

METHODS

Children treated for de novo AML on two Children's Oncology Group trials at institutions contributing to the Pediatric Health Information System (PHIS) database were included. The SDI was calculated via residential zip code data from the US Census Bureau. SS was identified via PHIS resource utilization codes. SS-death was defined as death within 2 weeks of an antecedent SS event. Patients were followed from 7 days after the start of chemotherapy until the first of end of front-line therapy, death, relapse, or removal from study. Multivariable-adjusted Cox regressions estimated hazard ratios (HRs) comparing time to first SS by SDI group.

RESULTS

The assembled cohort included 700 patients, with 207 (29.6%) sustaining at least one SS event. There were 233 (33%) in the SDI-5 group (highest disorganization). Adjusted time to incident SS did not statistically significantly differ by SDI (reference, SDI-1; SDI-2: HR, 0.84 [95% confidence interval (CI), 0.51-1.41]; SDI-3: HR, 0.70 [95% CI, 0.42-1.16]; SDI-4: HR, 0.97 [95% CI, 0.61-1.53]; SDI-5: HR, 0.72 [95% CI, 0.45-1.14]). Nine patients (4.4%) with SS experienced SS-death; seven of these patients (78%) were in SDI-4 or SDI-5.

CONCLUSIONS

In a large, nationally representative cohort of trial-enrolled pediatric patients with AML, there was no significant association between the SDI and time to SS.

Food Insecurity, Neighborhood Food Environment, and Health Disparities: State of the Science, Research Gaps and Opportunities

Food insecurity and the lack of access to affordable, nutritious food are associated with poor dietary quality and an increased risk of diet-related diseases, including cardiovascular disease, diabetes, and certain types of cancer. Those of lower socioeconomic status and racial and ethnic minority groups experience higher rates of food insecurity, are more likely to live in under-resourced food environments, and continue to bear the greatest burden of diet-related chronic diseases in the United States. Despite the growing body of literature in this area, there are still significant gaps in our understanding of the various pathways that link food insecurity and neighborhood food environments to racial/ethnic and socioeconomic disparities in health and the most effective intervention strategies to address these disparities. To better understand the science in this area, the National Institutes of Health, in collaboration with the Centers for Disease Control (CDC) and Prevention and the United States Department of Agriculture (USDA), convened a virtual 3-d workshop 21-23 September 2021: Food Insecurity, Neighborhood Food Environment, and Nutrition Health Disparities: State of the Science. The workshop brought together a diverse group of researchers, practitioners, policymakers, and federal partners with expertise in nutrition, the food environment, health and social policy, and behavioral and social sciences. The workshop had the following 3 research objectives: 1) summarize the state of the science and knowledge gaps related to food insecurity, neighborhood food environments, and nutrition health disparities, 2) identify research opportunities and strategies to address research gaps, and 3) examine evidence-based interventions and implementation approaches to address food insecurity and neighborhood food environments to promote health equity. This article summarizes workshop proceedings and describes research gaps and future opportunities that emerged from discussions.

Use of Community Engagement Studios to Adapt a Hybrid Effectiveness-Implementation Study of Social Incentives and Physical Activity for the STEP Together Study

Physical activity is known to contribute to good health, but most adults in the United States do not meet recommended physical activity guidelines. Social incentive interventions that leverage insights from behavioral economics have increased physical activity in short-term trials, but there is limited evidence of their effectiveness in community settings or their long-term effectiveness. The STEP Together study is a Hybrid Type 1 effectiveness-implementation study to address these evidence and implementation gaps. This paper describes the process of adapting study procedures prior to the effectiveness trial using Community Engagement (CE) Studios, facilitated meetings during which community members provide feedback on research projects. Six CE Studios were held with community members from the priority population. They were conducted remotely because of the COVID-19 pandemic. Fifteen liaisons representing 13 community organizations and 21 community members from different neighborhoods in Philadelphia participated. Three elements of the study design were modified based on feedback from the CE Studios: lowering the age requirement for an 'older adult', clarifying the definition of family members to include second-degree relatives, and adding a 6-month survey. These adaptations will improve the fit of the effectiveness trial to the local context and improve participant engagement and retention. CE Studios can be used to adapt intervention strategies and other aspects of study design during hybrid implementation-effectiveness trials. This approach was successfully used with remote online participation due to the COVID-19 pandemic and serves as a model for future community-engaged implementation research.

Availability of Recreation Facilities and Parks In Relation to Adolescent Participation in Organized Sports and Activity Programs

Most adolescents do not meet physical activity guidelines, so understanding facilitators and barriers is important. This study used surveys and geocoded location data to examine associations of availability of parks and recreation facilities with adolescent-reported participation in organized team sports and physical activity classes. The study was conducted with 928 adolescents aged 12-17 years, plus one parent/caretaker, recruited from two regions of the US. Adolescents' participation in teams and classes was positively associated with parents' perceptions of multiple available recreation environments, but not with objectively-measured availability. Having multiple nearby parks and recreation facilities may provide adolescents with more options for participating in preferred organized team sports and activity classes.

Feasibility and acceptability of mobile methods to assess home and neighborhood environments related to adolescent sleep

OBJECTIVE

A growing evidence base suggests home and neighborhood environmental exposures may influence adolescent sleep, but few studies have assessed these relationships using methods that account for time-varying, location-specific exposures, or multiple neighborhood contexts. This study aimed to assess the feasibility and acceptability of using smartphone global positioning system (GPS) tracking and ecological momentary assessment (EMA) to assess time-varying home and neighborhood environmental exposures hypothesized to be associated with adolescent sleep.

METHODS

Adolescents aged 15-17 years in Philadelphia completed 7 days of continuous smartphone GPS tracking, which was used to identify daily levels of exposure to geocoded neighborhood factors (eg, crime, green space). Four daily EMA surveys assessed home sleep environment (eg, noise, light), stress, health behaviors, and neighborhood perceptions. Feasibility and acceptability of GPS tracking and EMA were assessed, and distributions of daily environmental exposures were examined.

RESULTS

Among 25 teens (mean age 16, 56% male), there was a high level of GPS location data captured (median daily follow-up: 24 hours). Seventy-eight percent of EMA surveys were completed overall. Most participants (96%) reported no privacy concerns related to GPS tracking and minimal burden from EMA surveys. Exposures differed between participants' home neighborhoods and locations visited outside the home neighborhood (eg, higher crime away from home). Sleep environment disruptions were present on 29% of nights (most common: uncomfortable temperature) and were reported by 52% of adolescents.

CONCLUSIONS

Results demonstrate the feasibility and acceptability of mobile methods for assessing time-varying home and neighborhood exposures relevant to adolescent sleep for up to 1 week.

Effects of Sugary Beverage Text and Pictorial Warnings: A Randomized Trial

INTRODUCTION

Multiple U.S. localities have introduced legislation requiring sugar-sweetened beverage (SSB) warnings. This study effects of different warning designs on beverage selections and perceptions.

STUDY DESIGN

The study was an RCT.

SETTING/PARTICIPANTS

An online virtual convenience store and survey were used with a nationally representative sample of primary caregivers of 6-11-year-olds (n=961). Data were collected in January 2020 and analyzed in May-July 2020.

INTERVENTION

Participants were randomized to view SSBs with 1 of 4 front-of-package label designs: (1) no-warning control, (2) health-related text warning, (3) sugar pictorial warning (image of beverage sugar content in cubes/teaspoons/packets with health-related warning text), or (4) health pictorial warning (image of possible health consequences of overconsuming SSBs with health-related warning text).

MAIN OUTCOME MEASURES

Outcomes included participants' beverage choice for their child and perceptions of beverages, their assigned labels, and warning policies.

RESULTS

Proportionally fewer participants chose a SSB in the sugar pictorial warning condition (-13.4 percentage points; 95% CI= -21.6 to -0.1 percentage points; p=0.007) and in the health pictorial warning condition (-14.7 percentage points; 95% CI= -22.8 to -0.1 percentage points; p=0.004) compared to the control. Sugar pictorial warnings led to more accurate added-sugar content estimates than all conditions and greater label trust and support for sugar-sweetened beverage warning policies than health pictorial warnings.

CONCLUSIONS

SSB warning policies may be most effective if they mandate images of beverages' added sugar content accompanied by warning text.

Community Health Workers to Increase Cancer Screening: 3 Community Guide Systematic Reviews

INTRODUCTION

Many in the U.S. are not up to date with cancer screening. This systematic review examined the effectiveness of interventions engaging community health workers to increase breast, cervical, and colorectal cancer screening.

METHODS

Authors identified relevant publications from previous Community Guide systematic reviews of interventions to increase cancer screening (1966 through 2013) and from an update search (January 2014-November 2021). Studies written in English and published in peer-reviewed journals were included if they assessed interventions implemented in high-income countries; reported screening for breast, cervical, or colorectal cancer; and engaged community health workers to implement part or all of the interventions. Community health workers needed to come from or have close knowledge of the intervention community.

RESULTS

The review included 76 studies. Interventions engaging community health workers increased screening use for breast (median increase=11.5 percentage points, interquartile interval=5.5‒23.5), cervical (median increase=12.8 percentage points, interquartile interval=6.4‒21.0), and colorectal cancers (median increase=10.5 percentage points, interquartile interval=4.5‒17.5). Interventions were effective whether community health workers worked alone or as part of a team. Interventions increased cancer screening independent of race or ethnicity, income, or insurance status.

DISCUSSION

Interventions engaging community health workers are recommended by the Community Preventive Services Task Force to increase cancer screening. These interventions are typically implemented in communities where people are underserved to improve health and can enhance health equity. Further training and financial support for community health workers should be considered to increase cancer screening uptake.

Use of the Nutrition Environment Measures Survey: A Systematic Review

INTRODUCTION

The Nutrition Environment Measurement Survey (NEMS) measures were developed to assess the consumer food environment in stores and restaurants. NEMS tools have been widely used in research and adapted for diverse settings and populations in the 15 years since they were created. This systematic review examines the use and adaptations of these measures and what can be learned from published studies using NEMS tools.

METHODS

A comprehensive search of bibliographic databases was conducted from 2007 to September 2021, supplemented by backward searches and communications with authors, to identify research articles using NEMS tools. Data on purpose, key findings, sample characteristics, NEMS characteristics, and modifications were abstracted. Articles were categorized on the basis of study goals, NEMS tool(s) used, variables measured, and common themes.

RESULTS

A total of 190 articles from 18 countries were identified. Most studies (69.5%, n=123) used a modified version of NEMS tools. There were 23 intervention studies that used measures from NEMS tools or adaptations as outcomes, moderators, or process assessments. A total of 41% (n=78) of the articles evaluated inter-rater reliability, and 17% (n=33) evaluated test-retest reliability.

DISCUSSION

NEMS measures have played an important role in the growth of research on food environments and have helped researchers to explore the relationships among healthy food availability, demographic variables, eating behaviors, health outcomes, and intervention-driven changes in food environments. The food environment is constantly changing, so NEMS measures should continue to evolve. Researchers should document data quality of modifications and use in new settings.

Associations of home and neighborhood environments with children's physical activity in the U.S.-based Neighborhood Impact on Kids (NIK) longitudinal cohort study

INTRODUCTION

Physical activity is important for children's health and well-being. Supportiveness for physical activity of home and neighborhood environments may affect children's PA, but most studies are cross-sectional. We examined environmental predictors of change in children's physical activity over two years.

METHODS

Data were from the longitudinal, observational cohort study, 'Neighborhood Impact on Kids'. Participants were children (initially aged 6-12 years) and their parent/caregiver (n = 727 dyads) living in neighborhoods throughout San Diego County, California and King County (Seattle area), Washington, USA. Children's moderate-to-vigorous physical activity (MVPA) was measured using accelerometers at T1 (Time 1 or baseline, 2007-2009) and T2, the two-year follow-up. At T1, parents survey-reported on physical activity (PA) equipment at home and demographics. Neighborhood environment was measured using spatial data in Geographic Information Systems (intersection density; park availability) and in-person audits (informal play space near home; park-based PA facilities; land use; support for walking/cycling). Generalized additive mixed models estimated total effects, then direct effects, of environmental attributes on MVPA at T1. Two-way moderating effects of child's sex and age were examined at T1. To examine associations of environmental exposures with changes in MVPA, we estimated interaction effects of environmental attributes on the association between time and MVPA.

RESULTS

On average, children accumulated 146 min/day (standard deviation or SD = 53) of MVPA at T1, and 113 (SD = 58) min/day at T2. There were no significant total or direct effects of environmental attributes on MVPA at T1, and no significant two-way interaction effects of child's age and sex for T1 MVPA. Having informal play spaces proximal to home with more amenities was associated with less MVPA decline from T1 to T2. Higher residential density, higher land use mix, and higher number of PA facilities in nearby parks were unexpectedly associated with greater MVPA decline.

CONCLUSION

Higher quality informal play spaces close to home may help offset declines in MVPA during middle childhood, as they may promote unstructured active play with opportunities for parental or neighbor surveillance. Unexpectedly, environmental factors consistent with higher walkability were associated with greater declines in children's MVPA. As physical activity differs across the lifespan, so may environmental factors that facilitate it.

Testing a Prostate Cancer Educational Intervention in High-Burden Neighborhoods

To better capitalize on our enhanced understanding of prostate cancer (PCa) risk factors, it is important to better understand how knowledge and attitudes contribute to ethnic disparities in PCa outcomes. The goal of this study was to test the impact of a targeted PCa educational intervention vs. a healthy lifestyle educational control intervention on levels of knowledge, concern, and intention to screen for PCa.We recruited 239 men from neighborhoods with the highest PCa burden in Philadelphia. We assigned 118 men from two of the neighborhoods to the control group 121 men from 2 other neighborhoods to the intervention group. Repeated outcome assessment measures were obtained by administering the survey at baseline, post-session, 1 month post-session, and 4 months post-session.We conducted descriptive statistics to characterize the study sample and linear mixed effect regression models to analyze the intervention's effect on the outcomes. At baseline, we observed no differences in the outcomes between the PCa-targeted intervention and healthy lifestyle control groups.We found that knowledge of PCa and intention to screen increased significantly over time for both the control and intervention groups (p ≤ 0.01 at the 4-month follow-up). In contrast, change in the level of PCa concern was only significant for the intervention group immediately post-session and at 1-month follow-up (p = 0.04 and p = 0.01, respectively).This study showed that gathering at-risk men for discussions about PCa or other health concerns may increase their PCa knowledge and intention to talk to a doctor about PCa screening.

Location-specific psychosocial and environmental correlates of physical activity and sedentary time in young adolescents: preliminary evidence for location-specific approaches from a cross-sectional observational study

BACKGROUND

A better understanding of the extent to which psychosocial and environmental correlates of physical activity are specific to locations would inform intervention optimization.

PURPOSE

To investigate cross-sectional associations of location-general and location-specific variables with physical activity and sedentary time in three common locations adolescents spend time.

METHODS

Adolescents (N = 472,Mage = 14.1,SD = 1.5) wore an accelerometer and global positioning systems (GPS) tracker and self-reported on psychosocial (e.g., self-efficacy) and environmental (e.g., equipment) factors relevant to physical activity and sedentary time. We categorized each survey item based on whether it was specific to a location to generate psychosocial and environmental indices that were location-general or specific to either school, non-school, or home location. Physical activity (MVPA) and sedentary time were based on time/location match to home, school, or all "other" locations. Mixed-effects models investigated the relation of each index with location-specific activity.

RESULTS

The location-general and non-school physical activity psychosocial indices were related to greater MVPA at school and "other" locations. The school physical activity environment index was related to greater MVPA and less sedentary time at school. The home activity environment index was related to greater MVPA at home. The non-school sedentary psychosocial index was related to less sedentary time at home. Interactions among indices revealed adolescents with low support on one index benefited (i.e., exhibited more optimal behavior) from high support on another index (e.g., higher scores on the location-general PA psychosocial index moderated lower scores on the home PA environment index). Concurrent high support on two indices did not provide additional benefit.

CONCLUSIONS

No psychosocial or environment indices, including location-general indices, were related to activity in all locations. Most of the location-specific indices were associated with activity in the matching location(s). These findings provide preliminary evidence that psychosocial and environmental correlates of activity are location specific. Future studies should further develop location-specific measures and evaluate these constructs and whether interventions may be optimized by targeting location-specific psychosocial and environmental variables across multiple locations.

Correlates of attitudes toward COVID-19-related public health policies and prevention practices in six states

Objectives:

The COVID-19 pandemic rapidly impacted communities, however there is limited information about the beliefs, behaviors, and trust in government responses of populations across the country. It may be especially useful to understand state-based and regional differences that people reported early in the pandemic, to inform national and regional public health policies and communication strategies. This paper reports on correlates of perceptions of state and federal policies and prevention practices in six states with varying trajectories of COVID-19 cases and deaths, during the first major wave of the pandemic.

Methods:

A cross-sectional survey of COVID-19 policies, perceptions, and behaviors in six states (three in the northeast/mid-Atlantic and three in the southeastern United States), was conducted in April 2020 using an online platform of research volunteers. The survey asked about demographics; use of and belief about the effectiveness of preventive behaviors; experience with COVID-19 testing, diagnosis, quarantine, and hospitalization; risk behaviors and perception; opinion of local, state, and federal government guidelines and information; sources of information; and scales measuring time perspective and collectivism/individualism.

Results:

Responses from 1476 adults in six states showed that the most often-practiced prevention practices involved social distancing, and that reactions to federal government policies differed regionally and by political party affiliation.

Conclusions:

These findings improve understanding of how Americans view government responses to the pandemic, and their prevention practices, early in the pandemic. These data will help to create more effective public health policies to control the pandemic and achieve public support for control measures.

Associations of Neighborhood Safety and Collective Efficacy with Dietary Intake among Preschool-Aged Children and Mothers

Background: Positive neighborhood environments may promote healthier behaviors, yet few studies have examined associations between neighborhood social environment and diet. We examined associations of neighborhood perceived safety, collective efficacy, and violent crime with dietary intake among preschool-aged children and their mothers. Methods: We administered a cross-sectional survey to 300 mothers/female caregivers of Medicaid-enrolled 2- to 4-year-old children in Philadelphia. Mothers reported their own and their child's dietary intake using the validated Dietary Screener Questionnaire. Mixed-effects linear regression models assessed associations of perceived neighborhood safety, collective efficacy, and census tract-level violent crime with parent and child dietary intake, adjusted for individual, family, and neighborhood covariates. Results: Among mothers, higher perceived neighborhood safety and collective efficacy were associated with higher daily intake of fruits/vegetables (β = 0.35 cups, 95% CI: 0.12-0.58 and β = 0.30 cups, 95% CI: 0.08-0.52, comparing the highest with lowest tertile). Higher neighborhood-perceived safety was also associated with higher whole-grain intake among mothers (β = 0.14 ounces, 95% CI: 0.02-0.27) and children (β = 0.07 ounces, 95% CI: 0.01-0.13, comparing the highest with lowest tertile). Neighborhood social exposures were not associated with intake of added sugars or sugar-sweetened beverages for mothers or children, nor were lower levels of violent crime associated with any outcome. Conclusions: More favorable perceptions of neighborhood safety and collective efficacy were associated with a slightly higher consumption of some healthy foods among mothers and their young children. Future prospective research is needed to confirm these findings, explore potential mechanisms, and determine whether intervening on the social environment improves diet.

Development of a Survey of Sunscreen Use and Attitudes among Adults in Two Coastal States, 2019

Skin cancer is the most common form of cancer in the United States, and regular use of broad-spectrum sunscreens can prevent skin cancer. However, a new law in Hawaii that limits sunscreen choices due to the belief that some UV (ultraviolet) filters may damage coral reefs may reduce sunscreen use and increase skin-cancer risk. Because of this, there is a need for measurement tools to help understand consumer behavior and determinants of sunscreen purchase and use. The objectives of this study were (1) to test new questionnaire measures relevant to the Hawaii Sunscreen Ban; and (2) to assess adults’ knowledge, attitudes, and habits related to sunscreen in two other coastal states. This survey of adult residents of California and Florida was conducted in the summer of 2019. Newly developed scales addressed beliefs about effects of sunscreens on aquatic/marine environments and awareness of the Hawaii sunscreen ban. Respondents completed the survey twice to evaluate the test–retest reliability. Respondents (n = 162) were mainly female, White, and college-educated. New scales had moderate-to-high internal consistency and high test–retest reliability. Sunscreen use was high, sunburn was common, and knowledge and attitudes about sunscreen were modest. Most respondents did not know the specifics of the Hawaii Sunscreen Ban. In multivariate models, significant predictors of sunscreen use were being older, female, and having higher sunscreen knowledge. Sunscreen beliefs were not significantly associated with sunscreen use or sunburn. The findings support the use of the newly developed survey and suggest that more education about sunscreen and sunscreen ingredients is needed.

Design of a randomized controlled trial of digital health and community health worker support for diabetes management among low-income patients

BACKGROUND

Insulin-dependent diabetes is a challenging disease to manage and involves complex behaviors, such as self-monitoring of blood glucose. This can be especially challenging in the face of socioeconomic barriers and in the wake of the COVID-19 pandemic. Digital health self-monitoring interventions and community health worker support are promising and complementary best practices for improving diabetes-related health behaviors and outcomes. Yet, these strategies have not been tested in combination. This protocol paper describes the rationale and design of a trial that measures the combined effect of digital health and community health worker support on glucose self-monitoring and glycosylated hemoglobin.

METHODS

The study population was uninsured or publicly insured; lived in high-poverty, urban neighborhoods; and had poorly controlled diabetes mellitus with insulin dependence. The study consisted of three arms: usual diabetes care; digital health self-monitoring; or combined digital health and community health worker support. The primary outcome was adherence to blood glucose self-monitoring. The exploratory outcome was change in glycosylated hemoglobin.

CONCLUSION

The design of this trial was grounded in social justice and community engagement. The study protocols were designed in collaboration with frontline community health workers, the study aim was explicit about furthering knowledge useful for advancing health equity, and the population was focused on low-income people. This trial will advance knowledge of whether combining digital health and community health worker interventions can improve glucose self-monitoring and diabetes-related outcomes in a high-risk population.

Cost, reach, and representativeness of recruitment efforts for an online skin cancer risk reduction intervention trial for young adults

Despite its increasing use, few studies have reported on demographic representativeness and costs of research recruitment via social media. It was hypothesized that cost, reach, enrollment, and demographic representativeness would differ by social media recruitment approach. Participants were 18-25 year-olds at moderate to high risk of skin cancer based on phenotypic and behavioral characteristics. Paid Instagram, Facebook, and Twitter ads, unpaid social media posts by study staff, and unpaid referrals were used to recruit participants. Demographic and other characteristics of the sample were compared with the 2015 National Health Interview Survey (NHIS) sample. Analyses demonstrated significant differences among recruitment approaches regarding cost efficiency, study participation, and representativeness. Costs were compared across 4,274 individuals who completed eligibility screeners over a 7-month period from: Instagram, 44.6% (of the sample) = 1,907, $9 (per individual screened); Facebook, 31.5% = 1,345, $8; Twitter, 1% = 42, $178; unpaid posts by study staff, 10.6% and referred, 6.5%, $1. The lowest rates of study enrollment among individuals screened was for Twitter. Most demographic and skin cancer risk factors of study participants differed from those of the 2015 NHIS sample and across social media recruitment approaches. Considering recruitment costs and number of participants enrolled, Facebook and Instagram appeared to be the most useful approaches for recruiting 18-25 year-olds. Findings suggest that project budget, target population and representativeness, and participation goals should inform selection and/or combination of existing and emerging online recruitment approaches.

Effect of Financial Incentives and Environmental Strategies on Weight Loss in the Healthy Weigh Study: A Randomized Clinical Trial

IMPORTANCE

Modest weight loss can lead to meaningful risk reduction in adults with obesity. Although both behavioral economic incentives and environmental change strategies have shown promise for initial weight loss, to date they have not been combined, or compared, in a randomized clinical trial.

OBJECTIVE

To test the relative effectiveness of financial incentives and environmental strategies, alone and in combination, on initial weight loss and maintenance of weight loss in adults with obesity.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial was conducted from 2015 to 2019 at 3 large employers in Philadelphia, Pennsylvania. A 2-by-2 factorial design was used to compare the effects of lottery-based financial incentives, environmental strategies, and their combination vs usual care on weight loss and maintenance. Interventions were delivered via website, text messages, and social media. Participants included adult employees with a body mass index (BMI; weight in kilograms divided by height in meters squared) of 30 to 55 and at least 1 other cardiovascular risk factor. Data analysis was performed from June to July 2021.

INTERVENTIONS

Interventions included lottery-based financial incentives based on meeting weight loss goals, environmental change strategies tailored for individuals and delivered by text messages and social media, and combined incentives and environmental strategies.

MAIN OUTCOME AND MEASURES

The primary outcome was weight change from baseline to 18 months, measured in person.

RESULTS

A total of 344 participants were enrolled, with 86 participants each randomized to the financial incentives group, environmental strategies group, combined financial incentives and environmental strategies group, and usual care (control) group. Participants had a mean (SD) age of 45.6 (10.5) years and a mean (SD) BMI of 36.5 (7.1); 247 participants (71.8%) were women, 172 (50.0%) were Black, and 138 (40.1%) were White. At the primary end point of 18 months, participants in the incentives group lost a mean of 5.4 lb (95% CI, -11.3 to 0.5 lb [mean, 2.45 kg; 95% CI, -5.09 to 0.23 kg]), those in the environmental strategies group lost a mean of a 2.2 lb (95% CI, -7.7 to 3.3 lb [mean, 1.00 kg; 95% CI, -3.47 to 1.49 kg]), and the combination group lost a mean of 2.4 lb (95% CI, -8.2 to 3.3 lb [mean, 1.09 kg; 95% CI, -3.69 to 1.49 kg]) more than participants in the usual care group. Financial incentives, environmental change strategies, and their combination were not significantly more effective than usual care. At 24 months, after 6 months without an intervention, the difference in the change from baseline was similar to the 18-month results, with no significant differences among groups.

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, across all study groups, participants lost a modest amount of weight but those who received financial incentives, environmental change, or the combined intervention did not lose significantly more weight than those in the usual care group. Employees with obesity may benefit from more intensive individualized weight loss strategies.

Understanding the processes that Federally Qualified Health Centers use to select and implement colorectal cancer screening interventions: a qualitative study

Colorectal cancer (CRC) screening is highly effective at reducing cancer-related morbidity and mortality, yet screening rates remain suboptimal. Evidence-based interventions can increase screening rates, particularly when they target multiple levels (e.g., patients, providers, health care systems). However, effective interventions remain underutilized. Thus, there is a pressing need to build capacity to select and implement multilevel CRC screening interventions. We report on formative research aimed at understanding how Federally Qualified Health Center (FQHC) staff select and implement CRC screening interventions, which will inform development of capacity-building strategies. We report the qualitative findings from a study that used a mixed methods design, starting with a quantitative survey followed by a qualitative study. In-depth interviews were conducted with 28 staff from 14 FQHCs in 8 states. The Consolidated Framework for Implementation Research (CFIR) guided interview questions and data analysis. Related to the CFIR process domain, few respondents described conducting formal assessments of factors contributing to low screening rates prior to planning their interventions. Many described engaging champions, implementation leaders, and external change agents. Few described a systematic approach to executing implementation plans beyond conducting plan-do-study-act cycles. Reflection and evaluation consisted primarily of reviewing Uniform Data System performance measures. Findings also include themes related to factors influencing these implementation processes. Although FQHCs are implementing CRC screening interventions, they are not actively targeting the multilevel factors influencing their CRC screening rates. Our findings on gaps in FQHCs' implementation processes will inform development of strategies to build capacity to select and implement multilevel CRC screening interventions.

Consumers' Ability to Distinguish Between Milk Types: Results of Blind Taste Testing

The objective of this study was to assess consumers' ability to correctly identify different types of milk in a blind taste test and correlates of plans to purchase lower fat milk. Adults from 8 supermarkets in low-income neighborhoods tasted 3 types of unlabeled lower fat or fat-free milk samples and guessed the type of each sample. Of the 1074 participants, only 7.6% were able to identify all 3 unlabeled samples correctly. Most adults in this study reported consuming higher fat milk and could not correctly identify milk type by taste alone. Blind taste tests may encourage consumers to drink lower fat milk.

Environmental exposomics and lung cancer risk assessment in the Philadelphia metropolitan area using ZIP code-level hazard indices

To illustrate methods for assessing environmental exposures associated with lung cancer risk, we investigated anthropogenic based air pollutant data in a major metropolitan area using United States-Environmental Protection Agency (US-EPA) Toxic Release Inventory (TRI) (1987-2017), and PM2.5 (1998-2016) and NO2 (1996-2012) concentrations from NASA satellite data. We studied chemicals reported according to the following five exposome features: (1) International Agency for Research on Cancer (IARC) cancer grouping; (2) priority EPA polycyclic aromatic hydrocarbons (PAHs); (3) component of diesel exhaust; (4) status as a volatile organic compound (VOC); and (5) evidence of lung carcinogenesis. Published articles from PubChem were tallied for occurrences of 10 key characteristics of cancer-causing agents on those chemicals. Zone Improvement Plan (ZIP) codes with higher exposures were identified in two ways: (1) combined mean exposure from all features, and (2) hazard index derived through a multi-step multi-criteria decision analysis (MMCDA) process. VOCs, IARC Group 1 carcinogens consisted 82.3% and 11.5% of the reported TRI emissions, respectively. ZIP codes along major highways tended to have greater exposure. The MMCDA approach yielded hazard indices based on imputed toxicity, occurrence, and persistence for risk assessment. Despite many studies describing environmental exposures and lung cancer risk, this study develops a method to integrate these exposures into population-based exposure estimates that could be incorporated into future lung cancer screening trials and benefit public health surveillance of lung cancer incidence. Our methodology may be applied to probe other hazardous exposures for other cancers.

Pancreatic Cancer Clinical Treatment Trials Accrual: A Closer Look at Participation Rates

OBJECTIVES

Low rates of participation in cancer clinical trials are commonly reported, raising concerns about missed opportunities to engage patients in treatment trials. We reviewed eligibility for and enrollment in pancreatic cancer clinical trials for patients seen at a National Cancer Institute (NCI)-designated cancer center during 1 year, to calculate participation rates with detailed information to determine the best-case participation rate.

MATERIALS AND METHODS

This retrospective cohort study used the Abramson Cancer Center Cancer Registry, clinical trial protocols, and electronic medical records (EMRs) to determine eligibility for all available pancreatic cancer clinical trials. Patient characteristics and reasons for ineligibility were abstracted from EMRs. We then computed participation rates based on enrollment in trials using EMR and clinical trials monitoring data.

RESULTS

Of 233 new pancreatic cancer patients in 2014, 47 or 20% enrolled in a clinical trial (enrollment fraction). According to the EMR, of the 66 patients who were eligible for a trial, 54 (82% of eligible) accepted and 47 (71% of eligible) ultimately enrolled in a trial, 8 (12% of eligible) declined, and 4 (6% of eligible) had no record of patient decision. Enrollment in a trial by both the EMR and clinical trials database was confirmed for 71% of eligible patients.

CONCLUSIONS

This study reveals that 71% of newly diagnosed pancreatic cancer patients who were eligible for a trial were enrolled in a treatment trial. We contend that in-depth analysis, rather than enrollment fraction, should be used to inform the gap between actual participation and optimal clinical trial participation for cancer patients.

Accrual of Black participants to cancer clinical trials following a five-year prospective initiative of community outreach and engagement

100

Background: Accrual of Black participants to cancer clinical trials remains a major challenge across the country. Here, we report the outcomes of a five-year initiative of community outreach and engagement to improve enrollment of adult Black participants to clinical trials at the Abramson Cancer Center (ACC) at the University of Pennsylvania. Methods: Primary metrics were the percentage of Black patients among all cancer cases in our catchment area, the percentage of adult Black patients cared for at the ACC, and the percentage of adult Black participants enrolled on the three types of NCI-defined clinical trials. Results: In 2014, at baseline, Black residents comprised 19% of the population and 16.5% of cancer cases in our catchment area surrounding Philadelphia, but only 11.1% of ACC patients were Black. The percentages of Black participants accrued onto treatment, non-therapeutic interventional, and non-interventional trials were 12.2%, 8.3%, and 13.0%, respectively. We then established a center-wide program with community guidance to address these gaps. Key elements of the program included: 1) culturally tailored marketing strategies for cancer clinical trials; 2) plans for each protocol to facilitate Black participant enrollment; 3) new partnerships with faith-based organizations serving Black communities to conduct educational events about clinical trials; 4) pilot programs with Lyft and Ride Health to address transportation barriers; 5) patient education by nurse navigators regarding cancer and clinical trials; and 6) an improved informed consent process. These efforts reached more than 10,000 individuals in venues including churches, neighborhoods, community parks and centers, and health centers with formats ranging from educational forums to wellness fairs. Reassessing metrics in 2018, we found that the percentage of Black patients seen at ACC had increased to 16.2%, matching the percentage of Black cancer patients among all cancer cases in our catchment area (16.5%). Total cancer clinical trial accrual had increased from 9,308 participants in 2014 to 13,170 in 2018 (41.5% increase). The percentages of Black participants accrued onto treatment, non-therapeutic interventional, and non-interventional trials were 23.9%, 33.1%, and 22.5%, respectively – a 1.7- to 4.0-fold increase in five years and higher than the percentage of Black patients seen at the ACC. Conclusions: Our multifaceted, community-based engagement initiative to encourage clinical trial enrollment was associated with improved accrual of Black participants to cancer clinical trials. These findings also suggest that gaps in access to cancer centers are a key factor driving access to clinical trials. Medicaid expansion occurred concurrently in all states in our catchment area and its impact on accrual merits further research.

Messages Promoting Healthy Kids' Meals: An Online RCT

INTRODUCTION

Calorie labeling is now required on all large U.S. chain restaurant menus, but its influence on consumer behavior is mixed. This study examines whether different parent-targeted messages encourage parents to order lower-calorie meals for their children in a hypothetical online setting.

METHODS

An online RCT was conducted with sociodemographically diverse primary caregivers of children aged 6-12 years (data collected and analyzed in 2017-2019). Participants (N=2,373) were randomized to see 1 of 4 messages: (1) nonfood control, (2) kids' meals are the right size for children, (3) doctors recommend a 600 kcal per meal limit for kids, or (4) 600 kcal per meal is a generally recommended limit for kids. Participants ordered hypothetical meals for their children and themselves and rated meal and message perceptions.

RESULTS

There were no significant differences between conditions in calories ordered for children at either restaurant, although all 3 food message conditions ordered fewer calories for their children than the control (full service: 27-68 fewer kcal, fast food: 18-64 fewer kcal). The general 600 kcal/meal limit message consistently performed best across outcomes, encouraging parents to order the fewest calories for their children at both restaurants (5%-7% fewer) and significantly increasing their understanding of calorie recommendations for kids' meals. It also significantly reduced fast-food calories parents ordered for themselves compared with the control (-106 kcal, p=0.042).

CONCLUSIONS

Although no statistically significant differences were detected, messages with specific calorie recommendations for kids led parents to order lower-calorie restaurant meals for their children, suggesting that additional real-world studies with larger sample sizes are warranted.

Stigma, beliefs and perceptions regarding prostate cancer among Black and Latino men and women

BACKGROUND

Health disparities in prostate cancer (PC) are thought to reflect the complex interplay of socioeconomics, environment and biology. The potential impact of beliefs and perceptions about PC among Black and Latino populations on clinical disparities are not well understood. This qualitative study was conducted to assess current prevalent and pervasive stigma, beliefs and perceptions regarding PC among Blacks and Latinos living in a large metropolitan area, thereby identifying potentially modifiable barriers to care.

METHODS

Qualitative data were collected through four separate focus groups of self-identified Black and Latino adult men and women living in Philadelphia to better understand their perceptions of PC diagnosis, screening and treatment. Each focus group was single-sex and conducted by racial/ethnic group in order to assess possible differences in beliefs about PC based on gender and racial/ethnic affiliation. Audio recordings were transcribed verbatim by trained research assistants and qualitative data analysis was conducted using modified grounded theory.

RESULTS

There were a total of 34 participants: 19 Hispanics/Latinos and 15 Blacks, with equal numbers of men and women (n=17). Median age was 57 years (range: 18 to 85 years). Dominant themes that emerged with respect to PC diagnosis included the stigma surrounding this condition and the perceived role of an "unhealthy lifestyle" and certain sexual behaviors as risk factors for PC development. While the majority of participants acknowledged the importance of PC screening and early detection, discussion centered around the barriers to both the interest in seeking medical care and the likelihood of securing it. These barriers included misunderstanding of PC etiology, distrust of the medical profession, and financial/access limitations. Men expressed substantial confusion about PC screening guidelines. In the Black female group, the role of faith and religion in the course of disease was a major theme. Both Black and Latina females discussed the role of fear and avoidance around PC screening and treatment, as well as the prevalence of misinformation about PC in their familial and social communities.

CONCLUSION

Black and Latino focus groups revealed the existence of cultural beliefs, misunderstandings and fears pertaining to PC which could influence health-related behaviors. Some themes were common across groups; others suggested racial and gender predilections. Future targeted efforts focused on directly addressing prevalent misperceptions among underserved communities in urban settings could help to improve health literacy and equity in PC outcomes in these populations.

A Qualitative Study of Parents With Children 6 to 12 Years Old: Use of Restaurant Calorie Labels to Inform the Development of a Messaging Campaign

BACKGROUND

US law mandates that chain restaurants with 20 or more locations post calorie information on their menus to inform consumers and encourage healthy choices. Few qualitative studies have assessed how parents perceive and use this information when ordering for their children and what types of accompanying messages might increase use of calorie labels when ordering food.

OBJECTIVE

We aimed to better understand parents' perceptions and use of calorie labeling and the types of messages that might increase use.

DESIGN

We conducted 10 focus groups (n = 58) and 20 shop-along interviews (n = 20). Focus group participants discussed their hypothetical orders and restaurant experiences when dining with their children, and shop-along participants verbalized their decision processes while ordering at a restaurant. Both groups gave feedback on 4 public service messages aimed to increase healthier ordering for children. All interviews were voice-recorded and transcribed.

PARTICIPANTS/SETTING

Participants were primary caregivers of at least 1 child between 6 and 12 years who reported having less than a college education at the time of screening and who commonly ate at chain restaurants. Focus groups were conducted in a conference room, and shop-alongs were conducted in quick-serve and full-service chain restaurants around Philadelphia between August 2016 and May 2017.

ANALYSES

A modified grounded theory approach was used to extract themes from transcripts.

RESULTS

Thematic analysis of transcripts revealed 5 key themes: (1) parents' use of calorie labels; (2) differences across restaurant settings; (3) nonjudgmental information; (4) financial value and enjoyment of food; and (5) message preferences. These themes suggested that nonjudgmental, fact-based messages that highlight financial value, feelings of fullness, and easy meal component swaps without giving up the treatlike aspect of eating out may be particularly helpful for consumers.

CONCLUSIONS

These findings can inform current US Food and Drug Administration campaign efforts to support consumer use of calorie labels on menus.

Diet and Health Benefits Associated with In-Home Eating and Sharing Meals at Home: A Systematic Review

In-home and shared meals have been hypothesized to have positive effects. This narrative review examines research on the influence of in-home eating on diet quality, health outcomes, and family relationships. A combination search approach included a search of PubMed, backward searches of previous published reviews, and studies the authors were familiar with. A search identified 118 publications; 54 original studies and 11 review studies were included in this review. Each study was reviewed and summarized. The diverse designs precluded quantitative data synthesis. Relatively strong evidence from cross-sectional research supports the association of shared family meals with favorable dietary patterns in children and adolescents, including consumption of fruits, vegetables, and healthful nutrients. Correlational evidence links shared meals with health and psychosocial outcomes in youth, including less obesity, decreased risk for eating disorders, and academic achievement. Most evidence is cross-sectional, thus, limiting attribution of causality. There is insufficient evidence to conclude that interventions improve the frequency of shared meals, improve diet, or prevent child obesity. Despite the “common wisdom”, the evidence that in-home, shared meals, per se, have positive effects on diet quality, health outcomes, psychosocial outcomes, and family relationships is limited due to weak research designs and single-item measurement of the independent variable. More research, with stronger designs, is warranted.

Physical Activity, Sedentary Time, and Diet as Mediators of the Association Between TV Time and BMI in Youth

PURPOSE

This study examined dietary indicators, sedentary time, and physical activity as potential mediators of the association between TV time and BMIz in youth.

DESIGN

Cross-sectional study in 2 independent samples of youth.

SETTING

Data collection occurred by mail and telephone for adolescents and either at home or in medical settings for children.

SAMPLE

928 youth ages 12-16 and 756 youth ages 6-12 and a parent.

MEASURES

TV time, snacking/eating while watching TV, and a 3-day dietary recall were assessed via child/parent report. Physical activity and sedentary time were assessed by accelerometer wear.

ANALYSIS

Direct and indirect associations (through 8 diet and activity variables) of TV time with BMIz were tested in boys and girls in each sample.

RESULTS

TV time had a positive association with BMIz in 6-12 year old boys and girls. Direct associations emerged between TV time and the diet/activity variables, and between diet/activity variables and BMIz. Snacking/eating while watching TV had a significant positive association with BMIz in younger boys and mediated the association between TV time and BMIz (β = .06, p = .019; 25% attenuation).

CONCLUSIONS

Snacking/eating while watching TV may be a possible reason TV time is consistently associated with obesity in youth. Targeting reductions in TV time and associated snacking could improve health impacts.

The healthy food marketing strategies study: design, baseline characteristics, and supermarket compliance

Identifying effective strategies to promote healthy eating and reduce obesity is a priority in the USA, especially among low-income and minority groups, who often have less access to healthy food and higher rates of obesity. Efforts to improve food access have led to more supermarkets in low-income, ethnically diverse neighborhoods. However, this alone may not be enough to reduce food insecurity and improve residents' diet quality and health. This paper summarizes the design, methods, baseline findings, and supermarket in-store marketing strategy compliance for a randomized trial of the impact of healthy food marketing on the purchase of healthier "target" food items. Thirty-three supermarkets in low-income, high-minority neighborhoods in the metropolitan Philadelphia area were matched on store size and percentage of sales from government food assistance programs and randomly assigned to the intervention or control group. Healthy marketing strategies, including increased availability of healthier "target" products, prime shelf-placement and call-out promotion signs, and reduced availability of regular "comparison" products, were implemented in 16 intervention stores for an 18 month period for over 100 individual food items. Six product categories were studied: bread, checkout cooler beverages, cheese, frozen dinners, milk, and salty snacks. The primary outcome measure was weekly sales per store in each product category for 1 year preintervention and 18 months during the intervention. Compliance with the marketing strategies was assessed twice per month for the first 6 months and once a month thereafter. Store and neighborhood characteristics were not significantly different between control and intervention stores. Intercept surveys with customers to assess shopping habits and grocery marketing environment assessments to examine the food promotion environment were completed in the same six food categories. In intercept surveys, 51.0% of shoppers self-identified as overweight and 60.6% wanted to change their weight. Shoppers who typically purchased one type of food over another commonly did so out of habit or because the item was on sale. Findings revealed that preintervention sales of healthier "target" or regular "comparison" items did not differ between intervention and control stores for 1 year prior to intervention implementation. Rates of compliance with the healthy marketing strategies were high, averaging 76.5% over the first 12 months in all 16 stores. If healthy in-store marketing interventions are effective in this scaled-up, longer-term study, they should be translated into wider use in community supermarkets.

A Randomized Trial of Theory-Informed Appeals for Organ Donor Registration Using Internet Advertisements

Introduction

Many people do not register as organ donors. We developed 5 different brief appeals for organ donation that were disseminated online. The content was informed by theories of behavior change and studies of the specific cognitive barriers to organ donor registration.

Methods

One message was a persuasive narrative about a transplant recipient. Another message promoted the idea that organ donor registration is a social norm. The knowledge-based message communicated that 1 donor could improve the lives of 50 people. The message on reciprocity offered a free organ donation wristband, whether or not the participant registered as a donor. The message on control simply encouraged organ donation. Using Google AdWords, the messages were deployed randomly as banners of different sizes on diverse online sites and carried a link to an organ donor registration site. We measured clicks, page visits, and organ donor registrations.

Results

There were 5,156,048 impressions and 25,001 total clicks, a click-through rate of 0.49%. The messages on control and reciprocity both had the highest click-through rates of 0.51%. A total of 152 unique individuals requested wristbands and there were 52 total organ donor registration events. The message on reciprocity had the highest number of organ donor registrations (n = 18).

Conclusion

Online organ donation messages rapidly generated substantial attention through clicks, but no message led to a meaningful number of organ donor registrations. Future research may focus on effectively capturing the attention of viewers through social networks or other convenient online venues with less competition for attention than Internet banners.

Group-randomized trial of tailored brief shared decision-making to improve asthma control in urban black adults

AIMS

To assess the intervention effects of BREATHE (BRief intervention to Evaluate Asthma THErapy), a novel brief shared decision-making intervention and evaluate feasibility and acceptability of intervention procedures.

DESIGN

Group-randomized longitudinal pilot study.

METHODS

In total, 80 adults with uncontrolled persistent asthma participated in a trial comparing BREATHE (N = 40) to a dose-matched attention control intervention (N = 40). BREATHE is a one-time shared decision-making intervention delivered by clinicians during routine office visits. Ten clinicians were randomized and trained on BREATHE or the control condition. Participants were followed monthly for 3 months post-intervention. Data were collected from December 2017 - May 2019 and included surveys, lung function tests, and interviews.

RESULTS

Participants were Black/multiracial (100%) mostly female (83%) adults (mean age 45). BREATHE clinicians delivered BREATHE to all 40 participants with fidelity based on expert review of audiorecordings. While the control group reported improvements in asthma control at 1-month and 3-month follow-up, only BREATHE participants had better asthma control at each timepoint (β = 0.77; standard error (SE)[0.17]; p ≤ 0.0001; β = 0.71; SE[0.16]; p ≤ 0.0001; β = 0.54; SE[0.15]; p = .0004), exceeding the minimally important difference. BREATHE participants also perceived greater shared decision-making occurred during the intervention visit (β = 7.39; SE[3.51]; p = .03) and fewer symptoms at follow-up (e.g., fewer nights woken, less shortness of breath and less severity of symptoms) than the controls. Both groups reported improved adherence and fewer erroneous medication beliefs.

CONCLUSION

BREATHE is a promising brief tailored intervention that can be integrated into office visits using clinicians as interventionists. Thus, BREATHE offers a pragmatic approach to improving asthma outcomes and shared decision-making in a health disparity population.

IMPACT

The study addressed the important problem of uncontrolled asthma in a high-risk vulnerable population. Compared with the dose-matched attention control condition, participants receiving the novel brief tailored shared decision-making intervention had significant improvements in asthma outcomes and greater perceived engagement in shared decision-making. Brief interventions integrated into office visits and delivered by clinicians may offer a pragmatic approach to narrowing health disparity gaps. Future studies where other team members (e.g., office nurses, social workers) are trained in shared decision-making may address important implementation science challenges as it relates to adoption, maintenance, and dissemination.

Differences in adolescent activity and dietary behaviors across home, school, and other locations warrant location-specific intervention approaches

BACKGROUND

Investigation of physical activity and dietary behaviors across locations can inform "setting-specific" health behavior interventions and improve understanding of contextual vulnerabilities to poor health. This study examined how physical activity, sedentary time, and dietary behaviors differed across home, school, and other locations in young adolescents.

METHODS

Participants were adolescents aged 12-16 years from the Baltimore-Washington, DC and the Seattle areas from a larger cross-sectional study. Participants (n = 472) wore an accelerometer and Global Positioning Systems (GPS) tracker (Mean days = 5.12, SD = 1.62) to collect location-based physical activity and sedentary data. Participants (n = 789) completed 24-h dietary recalls to assess dietary behaviors and eating locations. Spatial analyses were performed to classify daily physical activity, sedentary time patterns, and dietary behaviors by location, categorized as home, school, and "other" locations.

RESULTS

Adolescents were least physically active at home (2.5 min/hour of wear time) and school (2.9 min/hour of wear time) compared to "other" locations (5.9 min/hour of wear time). Participants spent a slightly greater proportion of wear time in sedentary time when at school (41 min/hour of wear time) than at home (39 min/hour of wear time), and time in bouts lasting ≥30 min (10 min/hour of wear time) and mean sedentary bout duration (5 min) were highest at school. About 61% of daily energy intake occurred at home, 25% at school, and 14% at "other" locations. Proportionately to energy intake, daily added sugar intake (5 g/100 kcal), fruits and vegetables (0.16 servings/100 kcal), high calorie beverages (0.09 beverages/100 kcal), whole grains (0.04 servings/100 kcal), grams of fiber (0.65 g/100 kcal), and calories of fat (33 kcal/100 kcal) and saturated fat (12 kcal/100 kcal) consumed were nutritionally least favorable at "other" locations. Daily sweet and savory snacks consumed was highest at school (0.14 snacks/100 kcal).

CONCLUSIONS

Adolescents' health behaviors differed based on the location/environment they were in. Although dietary behaviors were generally more favorable in the home and school locations, physical activity was generally low and sedentary time was higher in these locations. Health behavior interventions that address the multiple locations in which adolescents spend time and use location-specific behavior change strategies should be explored to optimize health behaviors in each location.

How individual and neighborhood characteristics relate to health topic awareness and information seeking

Structural determinants of health like neighborhood are often overlooked in the context of understanding public awareness of health topics and health information seeking behaviors. Seeking health information is particularly relevant given that some communities have higher prevalence of disease than others. Using the Structural Influence Model of Health Communication (SIMHC), this paper examines how both individual and neighborhood level characteristics contribute to health communication outcomes such as being aware of health topics like cancer, obesity, and HIV, and whether or not individual seeking health-related information or coming across information in the course of their general media use. Respondents to the Southeastern Pennsylvania Household Health Survey (SEPa HHS), a county-stratified random sample of adults ages 18-75 years old, who completed the survey in 2015, were recontacted for participation in 2017. Over one-thousand respondents (n=1,005) completed the survey, and the final sample size for this analysis was 887. Individual level correlates included demographic factors and relevant lifestyle behaviors (e.g., smoking); neighborhood level variables- determined by ZIP Code- included such socioeconomic status (SES) measures as percent unemployed, percent with a high school education, and percent living in poverty. Multilevel modeling was used to determine whether there were random effects on the health communication outcomes of interest. Analyses showed our outcomes of interest did not vary across neighborhoods, whether they were treated as random or fixed effects. Different characterizations of neighborhood (e.g., census block group) and different indicators of neighborhood media environments may be more likely to demonstrate macro level effects on health communication outcomes.

•

Neighborhood characteristics were not related to awareness of different health topics or health information seeking behavior.

•

For most topics, reported awareness of health topics from the media was greater than from medical providers.

•

Information scanning was more prevalent among those with a college education and who were younger and female.

Abstract PR06: Geocoding and integrating multiple environmental exposomics sources: Assessing population hazard to lung carcinogens in 421 zip codes of a cancer center catchment area

To assess risk factors that contribute to lung cancer burden in the Abramson Cancer Center (ACC) catchment area, we integrated geospatial data of exposure to pollutants from publicly available EPA and NASA datasets. The study area covers the 421 zip codes that make up the 12 counties of the catchment area from which most of the ACC patients come. The counties include 5 that surround Philadelphia, 6 in New Jersey, and 1 in Delaware. Environmental exposure data, sourced from US-EPA Air Quality System (AQS) Data Mart, were focused on air pollutants since air pollution is recognized by the International Agency on Cancer (IARC) as a Group 1 human carcinogen. Exposomics data included: hourly, daily, and annual (1980 -2018) PM2.5, PM10, NO2; Hazardous Air Pollutants (HAPS); Volatile Organic Compounds (VOCs); (Air Quality Index) AQI; NONOxNOy monitoring; and annual Toxic Release Inventory (TRI) air emissions by chemical classifier and point source (1987 -2017). Annual NASA satellite-derived grids were incorporated for PM2.5 (1998-2016; 1 km resolution) and NOx (1997 - 2012; 10 km resolution). ESRI’s ArcGIS was used to develop programming scripts to automate the process of data integration, geocoding, and classifying chemical parameters by (1) status as a lung carcinogen with sufficient evidence of lung carcinogenesis; (2) status as one of the priority 16 EPA polycyclic aromatic hydrocarbons, as a surrogate marker of exposure to carcinogens; (3) status in the IARC rankings for Cancer Group; (4) status as a component of diesel exhaust; and (5) status as a VOC. 1-km search radius kernel density grids were generated for each air pollutant. We sliced the density estimates into ordinal rankings ranging from “10 = high” to “1 = low.” A hazard index may be generated by summing data layers of cumulative environmental exposomics in a process called map algebra. Spatial sorting and merging of exposome releases by facility, year, chemical and zip code concentration allow for addressing “low-hanging fruit” through summary statistics. Although the focus of this investigation is on lung cancer, the utility of the methodology may be applied to probe exposures related to other cancers. Incorporating more years or larger geographic areas of study may make exploring the risk of exposure possible for less prevalent cancers. In future studies, we are conducting statistical analysis to determine whether geocoded exposure data predict lung cancer risks in those vulnerable zip codes using electronic health record data of geolocations of lung cancer patients. This novel approach will help determine whether geocoded exposomics data are associated with cancer incidence. The hazard index was used to identify zip codes that are the most vulnerable to carcinogen exposure. Zip codes 19720, 19061, 08066, 08027, 19153, and 19145 scored highest on the hazard index based on cumulative exposure. (Supported by P30-CA-016520 and P30-ES013508.)

Developing and Testing Message Strategies to Reduce Indoor Tanning

Objectives: Indoor tanning, which is most common among 18-25-year-old white women, increases the risk of skin cancer. To address this problem, we developed and tested messages with a national sample of indoor tanners to determine beliefs that would encourage them to quit. Methods: Messages discouraging indoor tanning using different persuasive themes (skin cancer risk, appearance risk, well-being enhancement) were developed based on formative research and a review of intervention efforts. We conducted an online experiment to test the final messages with a national sample of 480 indoor tanners. Results: Messages that emphasized skin cancer risk out-performed messages that focused on well-being enhancement or damage to appearance in terms of intention to quit indoor tanning. Analyses revealed 2 key mediators: perceived argument strength and beliefs related to the effects of indoor tanning. Conclusions: Theory- and evidence-informed public health communications can contribute to improving health-related behaviors. Focusing on the risk of skin cancer may be the most effective strategy to reduce indoor tanning among young white women.

Facilitators and Barriers to Developing, Implementing, and Evaluating Healthy Vending Policies in Four Cities

Vending machines are a common source of low-nutrient, energy-dense snacks, and beverages. Many cities are beginning to adopt healthy vending policies in public areas, but evidence regarding best practices for developing, implementing, and evaluating these healthy vending polices is limited. This study used a mixed-methods, multiple case study design to examine healthy vending policies and initiatives in four cities. Data were collected between August 2017 and December 2017. Research staff worked with a designated contact person to coordinate site visits to each city where observations of the vending machines were conducted. Semistructured interviews were conducted with multiple stakeholders from each site and documents, including policies, vendor contracts, and nutrition standards, were reviewed. The following elements were identified as being essential to a healthy vending policy or initiative: having a champion and support from leadership, internal and external partnerships, and clear communication. Conducting regular compliance checks of the vending machines and the ability to obtain sales data, especially pre- and post-healthy vending policy sales data, continues to be a challenge. Stakeholders across all cities reported that concerns about profit-loss from the vendor and city revenue and procurement departments are barriers to adopting healthy vending policies. More research and evaluation are needed, as results are mixed regarding the impact on overall revenue/profits. This study yielded a variety of resources and "lessons learned" from those who have developed and implemented healthy vending policies and initiatives. This information should be used by others looking to influence healthier snacking behaviors through vending machines.

Testing General Versus Specific Behavioral Focus in Messaging for the Promotion of Sun Protection Behaviors

BACKGROUND

Recommendations for skin cancer prevention include behaviors such as using sunscreen, seeking shade, and wearing a shirt with sleeves, but the best way to persuasively communicate this information to the public is not clear.

PURPOSE

To test whether a messaging strategy using videos that focus on one specific behavior at a time versus a more general or multibehavior sun protection message is effective at changing attitudinal beliefs and intention with regard to sun protection behaviors.

METHODS

Online experiment among non-Hispanic white 18-49 year old adults in the USA. Participants were randomly assigned to one of four conditions, each one with health messages on a different sun protection prevention behavior: "using sunscreen" (Condition 1, n = 259), "seeking shade" (Condition 2, n = 245), or "covering up" (Condition 3, n = 289). Condition 4 (the control, n = 251) is a multibehavior message that equally promotes sunscreen, seeking shade, and covering up and features a general message on sun safety.

RESULTS

ANOVA and path analysis results suggest that messages which emphasize a single sun protection behavior compared with general sun safety messaging could potentially be a promising approach. The effectiveness of the videos in influencing attitudinal beliefs varied by behavior, with some gender and age moderation. There was an indirect effect on intention to use sunscreen.

CONCLUSIONS

This study advances our understanding of strategies for skin cancer prevention campaigns. Specifically, it suggests that focusing on a single sun protection behavior with targeted beliefs may be valuable as a first step in encouraging sun safety.

Putting Evidence Academies into action: Prostate cancer, nutrition, and tobacco control science

A well-documented challenge in moving public health research into practice is the extended time it takes to implement findings in clinical practice and communities. The Evidence Academy model (Rohweder et al., 2016), developed and first used in North Carolina, is a pragmatic, action-oriented model that aims to shorten this timeline by communicating cutting-edge findings directly to those who can use them and convening individuals working in a single topic area to network and plan activities for the future. The University of Pennsylvania Collaborating Center of the Cancer Prevention and Control Research Network (CPCRN) held three conferences based on the Evidence Academy model: one about prostate cancer in 2015, a second on food access and obesity prevention in 2017, and a third about tobacco control science in 2018. A diverse planning committee of stakeholders helped shape the content, focus,and format of each conference. Local and national experts presented findings to regional audiences of researchers, practitioners, government leaders, and community members. Each Evidence Academy included collaborators and speakers from other Prevention Research Centers (PRCs) and CPCRN network sites. Evaluations and outcomes indicated that the events were successful in achieving their goals and fostered ongoing relationships among attendees. This paper illustrates how the Evidence Academy model was used in a different region and describes lessons learned and follow-up activities that were initiated via the Evidence Academy and with input from participants. Lessons learned may be helpful in developing and evaluating future adaptations of the Evidence Academy model and/or the effectiveness of its components.

The Cancer Prevention and Control Research Network: Accelerating the implementation of evidence-based cancer prevention and control interventions

This editorial provides a high level overview of the articles included in this supplement.

An application of the Science Impact Framework to the Cancer Prevention and Control Research Network from 2014-2018

The Cancer Prevention and Control Research Network (CPCRN) is a strategic collaborative effort focused on accelerating the dissemination and implementation of evidence-based cancer prevention and control interventions to communities. In 2014, the CPCRN Coordinating Center began collecting information in alignment with the Centers for Disease Control and Prevention's (CDC) Science Impact Framework. The Science Impact Framework is a CDC-developed approach to trace and link CDC science to events and/or actions recognized as influential to public health, beyond peer-reviewed publications. The purpose of this paper is to highlight the impact of CPCRN activities using key indicators guided by the CDC's Science Impact Framework. We reviewed annual progress reports submitted by CPCRN centers from 2014 to 2019 to identify the impact indicators. The CPCRN activities were linked to four domains from the Science Impact Framework and its key indicators: Disseminating Science (presentations, training, general communication, and other communication reports), Creating Awareness (requests for expertise, and feedback), Catalyzing Action (grant applications, partnerships and collaborations, research & development, advocacy groups, office practice/point of care changes, and technology creating), and Effecting Change (building public health practice, creation of registries/surveillance, legal/policy changes, and change instilled). Overall, CPCRN activities demonstrate impact beyond peer-reviewed publications and thus should continue building scientific impact to ultimately influence health outcomes.

Use of Evidence-Based Interventions and Implementation Strategies to Increase Colorectal Cancer Screening in Federally Qualified Health Centers

While colorectal cancer (CRC) screening rates have been increasing in the general population, rates are considerably lower in Federally Qualified Health Centers (FQHCs), which serve a large proportion of uninsured and medically vulnerable patients. Efforts to screen eligible patients must be accelerated if we are to reach the national screening goal of 80% by 2018 and beyond. To inform this work, we conducted a survey of key informants at FQHCs in eight states to determine which evidence-based interventions (EBIs) to promote CRC screening are currently being used, and which implementation strategies are being employed to ensure that the interventions are executed as intended. One hundred and forty-eight FQHCs were invited to participate in the study, and 56 completed surveys were received for a response rate of 38%. Results demonstrated that provider reminder and recall systems were the most commonly used EBIs (44.6%) while the most commonly used implementation strategy was the identification of barriers (84.0%). The mean number of EBIs that were fully implemented at the centers was 2.4 (range 0-7) out of seven. Almost one-quarter of respondents indicated that their FQHCs were not using any EBIs to increase CRC screening. Full implementation of EBIs was correlated with higher CRC screening rates. These findings identify gaps as well as the preferences and needs of FQHCs in selecting and implementing EBIs for CRC screening.

Latent profile analysis of accelerometer-measured sleep, physical activity, and sedentary time and differences in health characteristics in adult women

Objectives

Independently, physical activity (PA), sedentary behavior (SB), and sleep are related to the development and progression of chronic diseases. Less is known about how rest-activity behaviors cluster within individuals and how rest-activity behavior profiles relate to health. In this study we aimed to investigate if adult women cluster into profiles based on how they accumulate rest-activity behavior (including accelerometer-measured PA, SB, and sleep), and if participant characteristics and health outcomes differ by profile membership.

Methods

A convenience sample of 372 women (mean age 55.38 + 10.16) were recruited from four US cities. Participants wore ActiGraph GT3X+ accelerometers on the hip and wrist for a week. Total daily minutes in moderate-to-vigorous PA (MVPA) and percentage of wear-time spent in SB was estimated from the hip device. Total sleep time (hours/minutes) and sleep efficiency (% of in bed time asleep) were estimated from the wrist device. Latent profile analysis (LPA) was performed to identify clusters of participants based on accumulation of the four rest-activity variables. Adjusted ANOVAs were conducted to explore differences in demographic characteristics and health outcomes across profiles.

Results

Rest-activity variables clustered to form five behavior profiles: Moderately Active Poor Sleepers (7%), Highly Actives (9%), Inactives (41%), Moderately Actives (28%), and Actives (15%). The Moderately Active Poor Sleepers (profile 1) had the lowest proportion of whites (35% vs 78–91%, p < .001) and college graduates (28% vs 68–90%, p = .004). Health outcomes did not vary significantly across all rest-activity profiles.

Conclusions

In this sample, women clustered within daily rest-activity behavior profiles. Identifying 24-hour behavior profiles can inform intervention population targets and innovative behavioral goals of multiple health behavior interventions.

Shared decision-making in the BREATHE asthma intervention trial: A research protocol

AIM

To evaluate the preliminary effectiveness of the BRief Evaluation of Asthma THerapy intervention, a 7-min primary care provider-delivered shared decision-making protocol that uses motivational interviewing to address erroneous asthma disease and medication beliefs.

DESIGN

A multi-centre masked two-arm group-randomized clinical trial.

METHODS

This 2-year pilot study is funded (September 2016) by the National Institute of Nursing Research. Eight providers will be randomized to one of two arms: the active intervention (N = 4) or a dose-matched attention control (N = 4). Providers will deliver the intervention to which they were randomized to 10 Black adult patients with uncontrolled asthma (N = 80). Patients will be followed three months postintervention to test the preliminary intervention effects on asthma control (primary outcome) and on medication adherence, lung function, and asthma-related quality of life (secondary outcomes).

DISCUSSION

This study will evaluate the preliminary impact of a novel shared decision-making intervention delivered in a real world setting to address erroneous disease and medication beliefs as a means of improving asthma control in Black adults. Results will inform a future, large-scale randomized trial with sufficient power to test the intervention's effectiveness.

IMPACT

Shared decision-making is an evidence-based intervention with proven effectiveness when implemented in the context of labour- and time-intensive research protocols. Medication adherence is linked with the marked disparities evident in poor and minority adults with asthma. Addressing this requires a novel multifactorial approach as we have proposed. To ensure sustainability, shared decision-making interventions must be adapted to and integrated into real-world settings.
