Culturally tailored lifestyle interventions for the prevention and management of type 2 diabetes in adults of Black African ancestry: a systematic review of tailoring methods and their effectiveness

Objective: To evaluate the cultural tailoring methods used in type 2 diabetes (T2D), prevention and management interventions for populations of Black African ancestry and to examine their effectiveness on measures of glycaemia. Design: Three databases were searched in October 2020; eligible studies used a randomised controlled trial (RCT) design to evaluate the effectiveness of culturally tailored lifestyle interventions compared with usual care for the prevention or management of T2D in adults of Black African ancestry. Cultural tailoring methods were evaluated using the Facilitator-Location-Language-Messaging (FiLLM) framework, whereby facilitator refers to delivery by individuals from the target community, language focuses on using native language or language appropriate to literacy levels, location refers to delivery in meaningful settings, and messaging is tailoring with relevant content and modes of delivery. Results: Sixteen RCT were identified, all from USA. The mean age of participants was 55 years, majority female. Six of fifteen RCT reported significant improvements in glycated haemoglobin (HbA1c) at 6 and 8 months; one, in prediabetes, reported significantly improved fasting plasma glucose. Diabetes knowledge improvement (5/7 studies) was associated with HbA1c improvement. The majority tailored to location (12/16), facilitators (11/16), messaging (9/16) and language (6/16) domains of FiLLM. Those with ethnically matched facilitators and those which tailored to more than one domain showed the greatest HbA1C benefits. Conclusion: This evidence supports the effectiveness of culturally tailored lifestyle interventions for T2D management in populations of Black African ancestry, with further RCT needed to evaluate interventions for T2D prevention and for communities outside of the USA.

Parent Support Programmes for Families Who are Immigrants: A Scoping Review

Parental support is of paramount importance in the promotion of positive parenting, strengthening parenthood and protecting children from disadvantages due to immigration experiences. The aim was to describe what is known about parent support programmes targeted to families who are immigrants. Electronic databases and the grey literature were systematically and comprehensively searched with no time/language restrictions. JBI approach and PRISMA-ScR were used to guide the review. N = 88 articles were sourced. Interventions were targeted to improve parental practices, skills and family wellbeing, usually through group-based methods. Most interventions included components of positive parenting and family communication. Identifying the needs of the target group and cultural tailoring were reported to be highly important in gaining acceptability, promoting engagement and producing benefits. Parent support programmes for families who are immigrants potentially improve positive parental practices and families’ wellbeing. There are many applicable and effective interventions to be exploited.

Incorporating an Increase in Plant-Based Food Choices into a Model of Culturally Responsive Care for Hispanic/Latino Children and Adults Who Are Overweight/Obese

Introduction: The national rate of obesity in US Hispanic/Latinos exceeds all other major ethnic subgroups and represents an important health disparity. Plant-based diet interventions that emphasize whole plant foods with minimal processing and less refined grains and sugar have shown have shown great promise in control of obesity, but there is a paucity of data translating this treatment effect to disparate populations. The objective of our study was to evaluate the efficacy of the Healthy Eating Lifestyle Program (HELP) for accomplishing weight management in a hospital-based, family centered, culturally tailored, plant-based diet intervention for Hispanic/Latino children who were overweight or obese. Methods: Our mixed methods evaluation included: (1) A one arm study to measure changes in body mass index (BMI) from pre- to post-intervention, and (2) A stakeholder analysis of the program staff. Results: For children ages 5–12 years who were overweight/obese, we found no evidence of excess weight gain evidenced by BMI Z scores (Zpost-pre = −0.02, p = 0.11). Among the parent/guardians who were overweight or obese, we found a decrease in BMI that was stronger in men (BMI post-pre = −0.75 kg/m2, p = 0.01) than in women (BMI post-pre = −0.12 kg/m2, p = 0.30). A program strength was the cultural tailoring of the plant-based diet choices. Conclusions: The evaluation raises the possibility that incorporating intervention components of HELP (plant-based food choices, family-based, cultural tailoring) into pediatric weight management can improve the standard of care.

Formative Research and Cultural Tailoring of a Substance Abuse Prevention Program for American Indian Youth: Findings From the Intertribal Talking Circle Intervention

Background. Substance use among American Indians (AIs) is a critical health issue and accounts for many health problems such as chronic liver disease, cirrhosis, behavioral health conditions, homicide, suicide, and motor vehicle accidents. In 2013, the highest rates of substance use and dependence were seen among AIs when compared to all other population groups, although these rates vary across different tribes. Among AI adolescents, high rates of substance use have been associated with environmental and historical factors, including poverty, historical trauma, bicultural stress, and changing tribal/familial roles. Our project, the Intertribal Talking Circle intervention, involved adapting, tailoring, implementing, and evaluating an existing intervention for AI youth of three tribal communities in the United States. Formative Results. Community partnership committees (CPCs) identified alcohol, marijuana, and prescription medications as high priority substances. CPC concerns focused on the increasing substance use in their communities and the corresponding negative impacts on families, stating a lack of coping skills, positive role models, and hope for the future as concerns for youth. Cultural Tailoring Process Results. Each site formed a CPC that culturally tailored the intervention for their tribal community. This included translating Keetoowah-Cherokee language, cultural practices, and symbolism into the local tribal customs for relevance. The CPCs were essential for incorporating local context and perceived concerns around AI adolescent substance use. These results may be helpful to other tribal communities developing/implementing substance use prevention interventions for AI youth. It is critical that Indigenous cultures and local context be factored into such programs.

Endorsement of Binge Eating Symptoms in a Sample of Predominantly Non-Hispanic Black Adolescents

Binge eating disorder (BED) as well as individual subthreshold binge eating symptoms are related to deleterious physical and socioemotional outcomes among adolescents. The present study examined the prevalence of specific binge eating behaviors among a sample of primarily non-Hispanic Black outpatients presenting to weight management and endocrinology clinics. Analyses are based on 103 adolescents (69.9% female, 66.9% non-Hispanic Black) who endorsed one or more binge eating symptoms on a nonstandardized clinical assessment patterned after Diagnostic Statistical Manual of Mental Disorders, Fifth Edition ( DSM-5) criteria. The most commonly endorsed symptom was eating in excess of what is considered normal (71.8%), while least commonly endorsed symptoms included guilt, distress, and embarrassment due to overeating (17.5% to 26.2%). More than half of the participants endorsed multiple specific binge eating symptoms. The level of subthreshold symptomatology reported underscores the importance of developmental and cultural tailoring of prevention and intervention efforts to address these behaviors as a means of curbing clinical-level onset of BED.

A Portfolio Analysis of Culturally Tailored Trials to Address Health and Healthcare Disparities

In 2010, Patient-Centered Outcomes Research Institute (PCORI) was authorized by Congress to improve the quality and relevance of evidence available to help patients, caregivers, employers, insurers, and policy makers make better-informed health decisions. We conducted a qualitative analysis of behavioral health trials in the PCORI Addressing Disparities portfolio to examine cultural tailoring strategies across the following priority populations: racial and ethnic minorities, rural populations, people with low-income or low socioeconomic status, individuals with disabilities, people with low health literacy, and lesbian, gay, bisexual, and transgender (LGBT) communities. The Common Strategies for Enhancing Cultural Appropriateness model was used to examine cultural tailoring strategies within trials. We hypothesized increased intersectionality within a patient population at risk for disparities would correlate with the dosage and type of cultural tailoring strategies applied. Thirty-three behavioral health trials applied cultural tailoring strategies and a majority of trials (n = 30) used three or more strategies. Trends in cultural tailoring were associated with certain racial and ethnic groups; however, increased use of tailoring was not associated with the number of priority populations included in a trial. The PCORI Addressing Disparities portfolio demonstrates how a range of cultural tailoring strategies are used, within comparative clinical effectiveness research trials, to address the needs and intersectionality of patients to reduce health and healthcare disparities.
