Culturally Sensitive Health Education in the Caribbean Diaspora: A Scoping Review

Context: The Caribbean diaspora in the United States is a diverse community that is afflicted with high morbidity and mortality due to preventable chronic diseases. Objective: Our goal is to determine which culturally sensitive health and nutrition educational modalities have the highest efficacy for improving general health in the Caribbean diaspora. Methods: A scoping literature review was performed on the MEDLINE, CINAHL, and Web of Science databases using terms related to health and nutrition in the Caribbean population. Original, peer-reviewed research published from 2010 to 2020, which took place in the U.S. and Caribbean countries, were included in our review. Results: We identified a total of nine articles that met our inclusion criteria. Rate differences for individual education program features were calculated to assess the likelihood of a positive impact on diet, physical activity, and diabetes. Conclusion: Our review helps to identify key educational modalities targeting diabetes, diet, and physical activity levels that can be used to meet the health and nutritional needs of the Caribbean diaspora population.


Introduction
The goal of this scoping review is to highlight the most culturally sensitive and effective health educational modalities available for the Caribbean diaspora in the United States. Culturally sensitive interventions, defined in literature as processes that incorporate a specific population's culture (e.g., norms, beliefs, values, and language), can be useful for addressing the needs of the Caribbean diaspora [1]. This scoping review is a derivative of the Caribbean Diaspora Healthy Nutrition Outreach Project (CDHNOP) research and community health initiative, which strives to improve health outcomes and reduce health disparities amongst Caribbean immigrants and their families in the US [2]. The Caribbean diaspora in the United States is a very diverse population made up of people originally from the Caribbean region. While these communities can be further subdivided by ethnic ancestry, we currently intend to treat them as a whole, with plans in the future for segmentation using the different subpopulations. As of 2017, approximately 4.4 million immigrants in the United States are from the Caribbean. Greater than 90% of these immigrants come from just five Caribbean territories: Cuba, Dominican Republic, Haiti, Jamaica, and Trinidad and Tobago. The three states with the largest concentration of Caribbean immigrants are Florida, New York, and New Jersey [3,4]. However, despite the significant population size in the United States, the Caribbean diaspora is significantly underrepresented with respect to focused research and health policy implementation. The CDHNOP's intercept survey research results have indicated that as much as 92% of participants reported that these revised education materials were helpful in making positive food and beverage choices. These surveys were performed to assess the effectiveness of the Interventions have shown to be effective tools in disease prevention and management. The US Preventative Services Task Force concluded that behavioral counseling interventions that promote healthy diets and physical activity have had some positive net benefit in adults with cardiovascular risk factors [22]. The high incidence rate of disease in the Caribbean population is especially concerning, considering the low rate of screening and regular check-ups in the population [23]. Multiple factors such as socioeconomic variables, cultural beliefs, language barriers, and structural barriers contribute to these statistics [24]. Despite increasing numbers of Caribbean immigrants, there have been few studies on effective and culturally appropriate interventions tailored for the Caribbean population in the US. Few studies have evaluated educational techniques to improve health outcomes that are specifically tailored for the Caribbean diaspora. The objective of this scoping literature review is to assess effective health educational modalities that can be appropriately adapted and applied to improve health outcomes in the Caribbean diaspora. In order to address this, we generated the following research question: In the Caribbean diaspora, what educational health programs are available to improve dietary or physical activity outcomes?

Search Strategy
Our team adopted and modified the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) protocol for performing our scoping literature review [25]. We used PICO search terms that evaluated Caribbean diaspora populations, the type of education program done as an intervention, and the outcomes measured. The specific search terms that were used in our search for each PICO category are shown in Table 1. The optional "comparison" component of the model was excluded from the search expression to avoid removing relevant literature from the results. The boolean operators "and" and "or" were used across and within parameters, respectively. The studies included were peer-reviewed, written in English, and published within the last ten years (2010-2020). The databases MEDLINE (264), CINAHL Complete (35), and Web of Science (120) were used to find publications. The types of studies included were journal articles, reviews, systematic reviews, meta-analyses, observational studies, and randomized controlled trials.
Web search history was also recorded in order to investigate the availability and accessibility of information related to the Caribbean diaspora. The information recorded included the web search terms and the corresponding number of articles that were subjectively identified to be related and queried in the literature review. Every paper that was identified in our search was bookmarked, saved, and then added to the literature review extraction chart. The chart detailed the title, year, author(s), methods, key findings, theme, and sources found. The sources were also added to EndNote for citations.

Inclusion Criteria
A total of 419 papers from the 3 listed databases were identified from our search strategy performed on 12 March 2020. After the removal of duplications, 347 unique papers remained. Two independent investigators conducted an initial review of the abstracts associated with each published work to ensure each was appropriate to the topic of Caribbean diaspora diet or physical activity education programs. Studies were also excluded if it was not an original peer-reviewed research report or had insufficient information on the educational program conducted or outcomes measured. The remaining 38 papers were read and evaluated in their entirety. Papers were further limited to research undertaken in the United States and Caribbean countries and those that studied adult populations (defined as age >18 years old). These parameters were implemented in order to focus on research that could be applied to the growing Caribbean population in the US and address their comorbidities. A total of 9 papers were retained after full evaluation and included in our analysis. The selection process is illustrated in Figure 1. associated with each published work to ensure each was appropriate to the topic of Caribbean diaspora diet or physical activity education programs. Studies were also excluded if it was not an original peer-reviewed research report or had insufficient information on the educational program conducted or outcomes measured. The remaining 38 papers were read and evaluated in their entirety.

A total of 9 papers were retained after full evaluation and included in our analysis. The selection process is illustrated in Figure 1.

Data Extraction
A data extraction chart was used to collect information on the nine papers that met our inclusion criteria. The two investigators independently filled out the data-charting form and discussed the results jointly. Studies were grouped into the themes of diet and physical activity. Many papers in our scoping review also assessed diabetes outcomes; therefore, it was included as an additional theme. The Template for Intervention Description and Replication (TIDieR) provides a 12-item checklist to improve the reporting and replicability of interventions [26]. We created a modified TIDieR table that was suited to the information we had available in our papers and incorporated additional items relevant to our scoping review. Our modified TIDieR table is presented in Table 2 and includes the additional items of theme, study design, quality assessment, and primary outcomes. To systematically analyze program features, each component of the educational program was extracted into our modified TIDieR table. We considered education programs to be culturally sensitive if they incorporated cultural or language tailoring, as referenced in the "Tailoring" column of Table 2.

Randomized controlled trial (RCT)
The information-motivation-behavioral skills (IMB) model of health behavior change informed the design of a brief, culturally tailored diabetes self-care intervention for Puerto Ricans with type 2 diabetes.
A flipchart, available in English and Spanish, presented information on food label reading, diet adherence, physical activity, and glycemic control (HbA1c). The session consisted of a brief introduction, information on diabetes prevalence in Puerto Ricans, motivational interviewing, and behavioral skills building. Patients were also provided with supplemental materials.

Nonrandomized controlled trial
Two types of education sessions were conducted: one-to-one and group. The group sessions were conducted at the health centers on days when clients came for regular three-monthly visits and were limited to 10-12 patients. Those unable to attend had education sessions at home when the LDFs visited. The education gave focus to the timing of meals in relation to prescription of diabetes medication, physical activities, blood glucose monitoring, and hypoglycemia.

Quality Assessment
Two investigators independently performed a quality assessment using the NIH quality assessment tool for the appropriate study type [36]. The investigators used the checklist criteria to assess the risk of bias of each study due to flaws in study design or implementation. The quality of each study was rated as "good", "fair", or "poor". Discrepancies on ratings between the two reviewers were discussed and resolved. The final quality assessment rating can be found in our modified TIDieR table (Table 2). Additionally, the results of this NIH quality assessment tool can be found in the Appendix A (Tables A1 and A2).

Data Analysis
We were unable to perform a meta-analysis due to a lack of homogeneity between education program types and the outcomes that were measured. Instead, we applied a previously defined method of calculating success rate differences that included and excluded the feature to determine which education program features are associated with successful outcomes [37,38]. Each study identified through the scoping review was evaluated on whether it had a program feature and whether the study documented a positive change in one or more outcome parameters based on our themes: diet, diabetes, and physical activity. The success rate difference of each feature on the outcome parameter was calculated from the difference between the success rate with the feature and the success rate without the feature. A success rate difference closer to 1.00 indicated a more positive association with the program feature and the outcome. Therefore, the more positive the success rate difference, the more likely it is that having the feature is associated with a positive effect on the outcome. A success rate difference of 0 suggests that the education program feature has no influence on the outcome. Negative success rate differences, closer to −1.00, indicate that not having the program feature was associated with a positive outcome.

Description of Studies
Overall, nine studies [27][28][29][30][31][32][33][34][35] were analyzed in this scoping literature review. A summary of the study characteristics can be found in Table 2. Three interventions took place in the United States, and six were conducted in the following Caribbean countries: Jamaica (1), Dominican Republic (2), Trinidad and Tobago (2), Guadeloupe (1). Seven papers examined interventions on education or behavior modification to improve the nutritional status or glycemic control of the participants. The two remaining papers studied the efficacy of an exercise program in increasing physical activity levels in Caribbean populations. Diabetes was the most common comorbidity, which was assessed in five studies.

Analysis of Features
Success rate differences for each educational program feature are found in Table 3. We identified and compared 33 distinct program features within 9 broad categories. Of these 33 program features, 21 features appeared in fewer than 5 studies, which makes discerning their generalizability more difficult. The remaining 12 characteristics appeared in 5 or more studies. Features with a positive success rate difference are highlighted in yellow, and features with a negative success rate difference are highlighted in blue. The magnitude of the positive or negative association of the feature with the outcome is indicated by the integer value.

Diet
Seven interventions [27][28][29][30][32][33][34] assessed outcomes related to diet, including confidence in healthy cooking, nutrition knowledge, diet adherence, and consumption of adequate nutrients. Four [27,[32][33][34] of these interventions documented statistically significant positive diet outcomes following intervention implementation. Features with positive success rate differences include language or literacy tailoring, cultural tailoring, delivery by a research team or a multidisciplinary team, delivered online or by written literature, through interac-tive/discussion or feedback, and interventions that included diet and psychosocial content. Interventions that were less than six months, with less than two intervention sessions per month, were also moderately associated with positive diet outcomes. Delivery of the diet education through audio-visual means was associated with high success.

Diabetes
Only one [32] out of the six [27][28][29][30][31][32] studies that assessed diabetes did not report a statistically significant decrease in HbA1c levels in intervention participants. Features with a positive success rate difference included programs designed for the individual or the healthcare provider, delivery by the healthcare provider, and, in a primary care or hospital-based setting, delivery face-to-face or through written literature or telephone, through didactic teaching or self-management education or feedback or diaries and reports. Programs that were six or more months were also associated with a positive likelihood of success. Programs that included diabetes content are associated with a positive success rate difference.

Physical Activity
Six studies [27][28][29][30]34,35] assessed physical activity as an outcome through increased physical activity levels, body mass index, and body weight. Two [34,35] of these studies reported statistically significant improved physical activity outcomes. Programs that occurred at a community setting, such as a fitness center, were moderately associated with having a positive impact on physical activity. Features that were highly associated with improved physical activity measures included interventions delivered by a multidisciplinary team and those that incorporated family support. Table 3. Success rate differences of education program features.  Table 3. Cont.

A success rate difference of 0 suggests that the education program feature has no influence on the outcome. Negative success rate differences, closer to −1.00, indicate that not having the program feature is associated with a positive outcome.

Discussion
There is limited research on effective health education strategies for the Caribbean population in the United States. Of the nine health education program studies our scoping literature review identified, three studies took place in the United States. As the Caribbean population in the United States continues to grow, more culturally appropriate education programs are required to meet their health needs and to prevent morbidity and mortality associated with diseases such as diabetes, cancer, stroke, and heart disease.
This review identified three themes of health education programs: diabetes, diet, and physical activity. Identification of successful program features within these categories has the potential to decrease comorbidities and chronic health conditions in the Caribbean diaspora. In 2018, the CDC estimated that 34.1 million adults, or 13.0% of the US adult population, had diabetes. Additionally, non-Hispanic Blacks had the highest incidence of diabetes. Projection trends show that the diabetes prevalence has steadily increased since 1999 and will continue to grow [39]. Previous research has shown further racial disparities with aggregated health data. For example, Afro-Caribbeans have a higher prevalence of diabetes and stroke compared to other African ethnic groups and Caucasians [5]. Risk factors for diabetes include smoking, overweight and obesity, physical inactivity, high blood pressure, and high cholesterol. Weight management, physical activity, and routine diabetes care can prevent diabetes-related complications [39].
Our scoping review results offer a bright outlook for using culturally tailored health education in the Caribbean diaspora. Our findings suggest that certain program features have a dramatic impact on patient health outcomes. Programs that are delivered in a clinical environment by a healthcare professional and center on patient self-management education are associated with a significant positive success rate with respect to patient HbA1c levels. This finding is meaningful and correlates with data from the parent CDHNOP study that showed most of the Caribbean focus group participants obtained health information from their doctor's office(s) [2]. In contrast, features such as interventions focused on behavior-related tasks and delivery of the intervention at a participant's home or by a nonhealthcare professional are shown to have less influence on patient HbA1c levels. Factors that may have some impact on these features include lack of access to healthcare and public assistance, lack of insurance, and various psychosocial issues [24]. These findings bear some similarities to previous systematic reviews performed on socially disadvantaged populations and women of black African, Caribbean, or Hispanic ethnicity [37,38]. Glazier et al. [37] found that cultural tailoring of interventions, community educators leading the education program, individualized one-on-one programs, inclusion of treatment algorithms, "focusing on behavior-related tasks", feedback, and high-intensity health education provided over a long duration provided the most reliable positive effects on improving diabetes care in socially disadvantaged populations. Gucciardi et al. [38] examined positive success rates of intervention features across multiple outcomes related to improving diabetes education, including diet, anthropometric and physical activity, and HbA1c. Their findings indicated that hospital-based education, group programs, usage of situational problem-solving, frequent sessions, and using dietitians as program providers had the broadest positive rate differences, affecting at least three outcomes. Program features that had a positive success rate difference closer to 1.00 included program delivery within participant communities or homes, interactive group discussions, specific feedback provided to participants by health education providers, diaries or log keeping, incorporation of psychosocial aspects, supervised exercise, and tailoring program features in the participant's native language.
Nutrition knowledge and confidence in healthy food preparation were additional outcomes evaluated in our scoping review. Our results show that the Caribbean diaspora may benefit from health education programs that specifically focus on cultural-and language-relevant nutrition education videos and visuals. Similar to the CDHNOP study, several culturally oriented studies in the past have noted similar effects. Attridge et al. [40] found that culturally sensitive health education in ethnic minorities had a positive impact on glycemic control and patient knowledge of diabetes, along with the associated healthy lifestyles. Israel et al. [41], Masuda et al. [42], and Naqshbandi et al. [43] each noted unique benefits from using community-based participatory research to minimize health disparities. These initiatives are valuable because they build collaborative partnerships between multiple stakeholders, emphasize culture and ethics, and link community action with social change.
Our findings also suggest physical activity programs that involved family support and a multidisciplinary approach in a community setting were associated with increased exercise levels and weight loss in participants. Programs incorporating physical activity in the Caribbean diaspora population will be necessary to decrease the prevalence of obesity and its associated negative health outcomes. Structural, societal, and cultural barriers impact the ability of individuals to increase their level of physical activity [24]. Alvarado et al. [24] found that Afro-Caribbean women in Barbados had a perceived reduction in their access to convenient and affordable exercise programs. The associated costs for programs incorporating physical activity were a common limitation noted by the reviewed articles [34,35]. In one study, 92 percent of participants reported that cost was an obstacle in continuing their fitness center membership, demonstrating a financial limitation in promoting sustainable behavioral modification [34]. Antoine-Jonville et al. [35] provided a free 10-week program to study participants and also recognized that future interventions should aim to decrease the costs of exercise programs. In addition to resource limitations, the Afro-Caribbean women interviewed by Alvarado et al. also referenced differing health beliefs about chronic disease and the role of physical activity in weight loss. For example, some of the women perceived chronic disease as random and inevitable and were, therefore, not convinced of the association between an active lifestyle and long-term health [24]. These findings highlight the importance of addressing cultural, societal, and cost limitations when constructing an appropriate physical activity program for the Caribbean diaspora.

Limitations
This scoping review has several limitations. First, only nine primary education program articles were found through our literature review, limiting the data available for analysis of effective education features. Due to the specific search performed, it is possible that other health education studies in this population were excluded. Second, the lack of homogeneity of studies and variable outcome parameters prohibited us from performing a meta-analysis. Additionally, while we hope to utilize this information in the Caribbean diaspora population, we included health programs that took place in Caribbean countries in our analysis due to the limited number of studies that were conducted in the United States. Our data may not fully account for different effect modifiers and confounding factors that are present in this other region. We were also limited to the descriptions of the educational program, as detailed in the original paper. This posed another challenge during data extraction as some papers did not describe study characteristics in the detail necessary for our modified TIDieR table.

Conclusions
There is a lack of data behind effective and culturally sensitive health education programs tailored for the Caribbean population in the United States. This scoping literature review highlights several health education program features that are associated with high success rates in improving diabetes, nutrition, and physical activity in the Caribbean population. Implementing effective health education in the Caribbean diaspora can improve the health of each individual member, reduce the burden on the healthcare system, and will eventually be applied to this underserved, underrepresented demographic nationally.
