Integrating Systems Science and Community-Based Participatory Research to Achieve Health Equity

Unanswered questions about racial and socioeconomic health disparities may be addressed using community-based participatory research and systems science. Community-based participatory research is an orientation to research that prioritizes developing capacity, improving trust, and translating knowledge to action. Systems science provides research methods to study dynamic and interrelated forces that shape health disparities. Community-based participatory research and systems science are complementary, but their integration requires more research. We discuss paradigmatic, socioecological, capacity-building, colearning, and translational synergies that help advance progress toward health equity.

Predictors of Uncontrolled Hypertension in the Stroke Belt

Inadequate control of high systolic blood pressure in older adults has been largely attributable to poor control of overall hypertension (HTN). The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) guidelines emphasize the importance of controlling isolated systolic HTN in older adults. The study examined demographics, self‐reported health information, and clinical measures as predictors of uncontrolled HTN among individuals taking antihypertensive medications. The Community Initiative to Eliminate Stroke, a stroke risk factor screening and prevention project, collected data in two North Carolina counties. Statistical modeling of predictors included odds ratios (ORs) and logistic regression analyses. Of the 2663 participants, 43.5% and 22.8% had uncontrolled systolic and diastolic HTN, respectively. African Americans were more likely to have uncontrolled systolic (60%) or diastolic HTN (70.9%) compared with whites (40% and 29.1%, respectively). Participants 55 years and older were more likely to have uncontrolled systolic HTN compared with younger individuals. Regression analyses showed that race (OR, 1.239; P=.00), age (OR, 1.683; P=.00), and nonadherence with medications (OR, 2.593; P=.00) were significant predictors of uncontrolled systolic HTN. Future interventions should focus on improving management of isolated systolic HTN in older adults and African Americans to increase overall control of HTN.

Stakeholder Perspectives on Creating and Maintaining Trust in Community–Academic Research Partnerships

Community–academic research partnerships aim to build stakeholder trust in order to improve the reach and translation of health research, but there is limited empirical research regarding effective ways to build trust. This multisite study was launched to identify similarities and differences among stakeholders’ perspectives of antecedents to trust in research partnerships. In 2013-2014, we conducted a mixed-methods concept mapping study with participants from three major stakeholder groups who identified and rated the importance of different antecedents of trust on a 5-point Likert-type scale. Study participants were community members (n = 66), health care providers (n = 38), and academic researchers (n = 44). All stakeholder groups rated “authentic communication” and “reciprocal relationships” the highest in importance. Community members rated “communication/methodology to resolve problems” (M = 4.23, SD = 0.58) significantly higher than academic researchers (M = 3.87, SD = 0.67) and health care providers (M = 3.89, SD = 0.62; p < .01) and had different perspectives regarding the importance of issues related to “sustainability.” The importance of communication and relationships across stakeholders indicates the importance of colearning processes that involve the exchange of knowledge and skills. The differences uncovered suggest specific areas where attention and skill building may be needed to improve trust within partnerships. More research on how partnerships can improve communication specific to problem solving and sustainability is merited.

Experiences of Latinos with limited English proficiency with patient registration systems and their interactions with clinic front office staff: an exploratory study to inform community-based translational research in North Carolina

BackgroundHealth services research of Latinos with limited English proficiency (LEP) have largely focused on studying disparities related to patient-provider communication. Less is known about their non-provider interactions such as those with patient registration systems and clinic front office staff; these interactions precede the encounter with providers and may shape how comfortable patients feel about their overall health services experience. This study explored Latino patients with LEP experiences with, and expectations for, interactions with patient registration systems and front office staff.MethodsWe conducted 20 in-depth interviews with Latinos with LEP (≥18 years of age) who seek health services in the Piedmont Triad region, North Carolina. We analyzed participants’ quotes and identified themes by using a constant comparison method. This research was conducted by a community-academic partnership; partners were engaged in study design, instrument development, recruitment, data analysis, and manuscript writing.ResultsQualitative analysis allowed us to identify the following recurring themes: 1) inconsistent registration of multiple surnames may contribute to patient misidentification errors and delays in receiving health care; 2) lack of Spanish language services in front office medical settings negatively affect care coordination and satisfaction with health care; and 3) perceived discrimination generates patients’ mistrust in front office staff and discomfort with services.ConclusionLatino patients in North Carolina experience health services barriers unique to their LEP background. Participants identified ways in which the lack of cultural and linguistic competence of front office staff negatively affect their experiences seeking health services. Healthcare organizations need to support their staff to encourage patient-centered principles.

Evaluating Teach One Reach One—An STI/HIV Risk-Reduction Intervention to Enhance Adult–Youth Communication About Sex and Reduce the Burden of HIV/STI:

Purpose: Parents and caregivers play an important role in sexual socialization of youth, often serving as the primary source of information about sex. For African American rural youth who experience disparate rates of HIV/sexually transmitted infection, improving caregiver–youth communication about sexual topics may help to reduce risky behaviors. This study assessed the impact of an intervention to improve sexual topic communication. Design: A Preintervention–postintervention, quasi-experimental, controlled, and community-based trial. Setting: Intervention was in 2 rural North Carolina counties with comparison group in 3 adjacent counties. Subjects: Participants (n = 249) were parents, caregivers, or parental figures for African American youth aged 10 to 14. Intervention: Twelve-session curriculum for participating dyads. Measures: Audio computer-assisted self-interview to assess changes at 9 months from baseline in communication about general and sensitive sex topics and overall communication about sex. Analysis: Multivariable models were used to examine the differences between the changes in mean of scores for intervention and comparison groups. Results: Statistically significant differences in changes in mean scores for communication about general sex topics (P < .0001), communication about sensitive sex topics (P < .0001), and overall communication about sex (P < .0001) existed. Differences in change in mean scores remained significant after adjusting baseline scores and other variables in the multivariate models. Conclusions: In Teach One Reach One intervention, adult participants reported improved communication about sex, an important element to support risk reduction among youth in high-prevalence areas.

Extending systems thinking in planning and evaluation using group concept mapping and system dynamics to tackle complex problems

Group concept mapping (GCM) has been successfully employed in program planning and evaluation for over 25 years. The broader set of systems thinking methodologies (of which GCM is one), have only recently found their way into the field. We present an overview of systems thinking emerging from a system dynamics (SD) perspective, and illustrate the potential synergy between GCM and SD. As with GCM, participatory processes are frequently employed when building SD models; however, it can be challenging to engage a large and diverse group of stakeholders in the iterative cycles of divergent thinking and consensus building required, while maintaining a broad perspective on the issue being studied. GCM provides a compelling resource for overcoming this challenge, by richly engaging a diverse set of stakeholders in broad exploration, structuring, and prioritization. SD provides an opportunity to extend GCM findings by embedding constructs in a testable hypothesis (SD model) describing how system structure and changes in constructs affect outcomes over time. SD can be used to simulate the hypothesized dynamics inherent in GCM concept maps. We illustrate the potential of the marriage of these methodologies in a case study of BECOMING, a federally-funded program aimed at strengthening the cross-sector system of care for youth with severe emotional disturbances.

Bridging Research, Practice, and Policy: The "Evidence Academy" Conference Model.

Innovative models to facilitate more rapid uptake of research findings into practice are urgently needed. Community members who engage in research can accelerate this process by acting as adoption agents. We implemented an Evidence Academy conference model bringing together researchers, health care professionals, advocates, and policy makers across North Carolina to discuss high-impact, life-saving study results. The overall goal is to develop dissemination and implementation strategies for translating evidence into practice and policy. Each 1-day, single-theme, regional meeting focuses on a leading community-identified health priority. The model capitalizes on the power of diverse local networks to encourage broad, common awareness of new research findings. Furthermore, it emphasizes critical reflection and active group discussion on how to incorporate new evidence within and across organizations, health care systems, and communities. During the concluding session, participants are asked to articulate action plans relevant to their individual interests, work setting, or area of expertise.

Adolescents and parental caregivers as lay health advisers in a community-based risk reduction intervention for youth: baseline data from Teach One, Reach One

ABSTRACT The purpose of the current study is to describe the demographic, behavioral, and psychosocial characteristics of adolescent and caregiver lay health advisers (LHAs) participating in an intervention designed to reduce risk behaviors among rural African-American adolescents. Teach One, Reach One integrates constructs from the Theory of Planned Behavior and Social Cognitive Theory. It acknowledges that changing the sexual behaviors of African-American adolescents requires changing ones knowledge, attitudes, normative beliefs about the behavior of peers, and self-efficacy regarding adolescent sexual behavior, parent–teen communication about sex, and healthy dating relations among adolescents. Study participants completed baseline questionnaires assessing demographics and psychosocial determinants (knowledge, attitudes, perceived social norms, and self-efficacy) of sexual behaviors. Sixty-two adolescent and caregiver dyads participated. Caregivers included biological parents, legal guardians, or other parental figures. Strengths and areas in need of improvement were determined using median splits. Few adolescents had initiated sex. Their strengths included high levels of open parent–teen communication; positive attitudes and normative beliefs regarding both sex communication and healthy dating relationships; and high knowledge and self-efficacy for healthy dating behaviors. Areas needing improvement included low knowledge, unfavorable attitudes, poor normative beliefs, and low self-efficacy regarding condom use. Caregiver strengths included positive attitudes, normative beliefs, and self-efficacy for sex communication; positive attitudes and self-efficacy for condom use; and low acceptance of couple violence. Areas needing improvement included low levels of actual communication about sex and low knowledge about effective communication strategies and condom use. The current study highlights the value of assessing baseline characteristics of LHAs prior to intervention implementation, as it enables a better understanding of the key characteristics necessary for planning and implementing interventions, as well as engaging in targeted training activities.

Development of a Systems Science Curriculum to Engage Rural African American Teens in Understanding and Addressing Childhood Obesity Prevention

Engaging youth from racial and ethnic minority communities as leaders for change is a potential strategy to mobilize support for addressing childhood obesity, but there are limited curricula designed to help youth understand the complex influences on obesity. Our aim was to develop and pilot test a systems science curriculum to elicit rural African American youth perspectives on childhood obesity and enhance their understanding of and support for obesity prevention solutions. The curriculum was designed so it could be integrated with existing positive youth development curricula that help youth advocate for and implement identified solutions. We conducted four workshop sessions with youth that engaged them in systems learning activities such as guided systems diagramming activities. The participants (n = 21) completed validated surveys presession and postsession that assessed their causal attributions of obesity and support for obesity prevention policies. The youths’ perception that environmental factors cause obesity increased (p < .05), and perceptions that individual behavior and biology cause obesity did not change. Their support for policies that addressed food access and food pricing significantly increased (p < .05). The youths’ system diagrams elucidated links between multilevel factors such as personal attitudes, social influence, and the built environment, which provides important information for designing synergistic solutions. The changes we observed in youths’ perceptions of obesity and support for policy changes have important implications for youths’ interest and willingness to advocate for social and environmental changes in their community. The strategies have a promising role in supporting community mobilization to address childhood obesity.

Understanding the relationship between religiosity and caregiver–adolescent communication about sex within African-American families

Caregiver–adolescent communication about sex plays a critical role in the sexual socialization of youth. Many caregivers, however, do not engage their youth in such conversations, potentially placing them at risk for negative sexual health outcomes. Lack of caregiver–adolescent communication about sex may be particularly harmful for rural African American youth, as they often report early sex initiation and are disproportionately impacted by STIs. Moreover, sexual communication may be particularly challenging for families with strong religious backgrounds, potentially affecting the occurrence and breadth of topics covered during communication. Study aims were to: determine whether there was a relationship between caregiver religiosity and type of topics covered during communication about sex (e.g., general sexual health vs. positive aspects of sexuality) among 435 caregivers of early adolescent, African American youth; and if so, identify factors that might explain how religiosity affects communication about sex. Results indicated that caregiver religiosity was positively associated with communication about general, but not positive aspects of sexuality for caregivers of males. Attitudes towards communication about sex and open communication style mediated the relationship. There was no association between religiosity and communication about sex for caregivers of females. The findings from this study could provide a base to better understand and support the sexual socialization process within religious, African American families.
