This study examined the responses of Latino community residents diagnosed with pre-diabetes using a complex convergent mixed methods design nested within a three-factor factorial design (age, language, and gender) to understand the intervention contents and activities that are most important to study participants for helping them to prevent the development and onset of type 2 diabetes (T2D). Chapter 1 introduces the topic and provides background literature. Chapter 2 systematically synthesized findings from diabetes prevention studies to identify efficacious intervention components and social contextual resources that have been used to support diabetes prevention in Latinos who are prediabetic or at risk of developing diabetes. Chapter 3 analyzed the qualitative portion of one section within the Latino Lifestyles study protocol. Based on the Integrative Mixed Methods (IMM) methodology, we conducted a thematic analysis to identify emergent themes for each of the three focus questions, as administered in individual interviews with 28 Latino and Latina participants. Chapter 4 utilized the findings from Chapter 3 to examine the levels and associations of three potential moderator variables: (a) health motivation, (b) diabetes awareness, and (c) diabetes concern among Latinos diagnosed with prediabetes. A 2x2 cross-tabulation analysis tested group differences in the mention of response phrases as examined by two levels (high versus low) of the potential moderator variables. The study results offered meaningful intervention components such as healthy cooking classes and assistance with lifestyle changes related to diet and exercise for themselves and their families, as expressed by the participants. These findings provide informative intervention components for developing a Latino community-based diabetes prevention program designed to enhance engagement and lifestyle changes for individuals diagnosed with prediabetes.

Background. Type 2 Diabetes Mellitus (T2DM) is a leading cause of health disparities, among Hispanic populations, which are disproportionately afflicted by T2DM. The growing research strongly argues that diabetes treatment interventions should be culturally sensitive to address the needs of their target populations. Nonetheless, there is little consensus regarding the necessary components of a culturally sensitive intervention. This review will examine the intervention contents and activities, and the strategies that have been implemented into culturally sensitive diabetes treatment interventions. This review will also to observe how interventions handle complex issues such as the heterogeneity of Hispanic populations and communities. The overarching research questions examined in this study were, “What are the core components of the culturally tailored diabetes interventions currently implemented with Hispanic populations in the US, and why are they needed?” and 2) “How are studies evaluating the impact of their interventions, and how can the proposed study designs be improved?” Method. A systematic review across 3 databases was used to identify culturally sensitive diabetes treatment interventions (CSDTI) developed for Hispanic populations. Accordingly, we searched for studies designed to treat Hispanic individuals already diagnosed with having T2DM. All identified studies provided information on the core components of these culturally sensitive interventions, while only studies that included a control or comparison group were used to assess how the studies evaluated outcomes. Results. First, we examined intervention effects as examined from two study designs. We examined a total of [17] interventions in this section. Our review of one study design (Design #1 Studies) includes 12 studies that developed a culturally sensitive intervention and evaluated it using a one-group pretest posttest design, or did not evaluate their intervention at all. A second study design (Design #2 Studies) includes 5 studies. These consisted of a two-group randomized controlled field study that conducted pre-post analyses of the culturally adapted intervention comparing it against a control or comparison group. The heterogeneity of all studies made a conventional meta-analysis impossible. Second, another review section focused on examining and describing various culturally sensitive core components, we examined a total of 17 studies to describe the types of culturally sensitive components that were incorporated into the diabetes treatment intervention. This analysis resulted in a list of 11 general types of culturally sensitive components as included within these 17 interventions. Of the articles that used control or comparison groups, the manner in which interventions evaluated different outcome measures and their conclusions regarding success were examined. Discussion. The culturally sensitive aspects identified from these articles were used to address diverse issues that included: (a) communication barriers, (b) the inclusion of cultural relevant content, for relevance to Hispanic/Latinx patients’ lives, (c) selecting appropriate channels and settings for interventions, and (d) addressing specific cultural values, traditions, and beliefs that can either help or hinder healthy behaviors. It should be noted that the Hispanic populations are extremely heterogeneous, and so interventions that would be sensitive culturally to some sectors of a Hispanic community may not be sensitive to other Hispanic sectors of that same community. The issue of heterogeneity of Hispanic communities was addressed well by the authors of some articles and ignored by others. Conclusions. It was ultimately impossible draw quantitative conclusions regarding the efficacy or effectiveness of these two types of diabetes treatment interventions (CSDTIs) as delivered to their targeted sample of Hispanic participants. An emerging conclusion is that factors including ethics, cost, and lack of community acceptance, may constitute factors contributing to the higher proportion of one-group pre-test post-test designs and lower proportion of rigorous scientific designs. In the latter case, some communities oppose the use of randomized controlled studies within their community, and thus that objection may explain the low numbers of these randomized controlled studies. The use of viable and rigorous alternatives to RCTs have been proposed to address this community concern. In this review, the author sought to conduct comparative studies between culturally adapted interventions and their associated unaltered or minimally altered evidence-based interventions, although there exists various difficulties that are associated with the conduct of these analyses. Core components of CSDTIs for Hispanic adults were identified, and their purposes were explained. Additionally, suggestions for improvement to studies were made, to aid in improving our knowledge of CSDTIs through future studies.
