Facilitators and Barriers to Implementation and Sustainability of Nutrition and Physical Activity Interventions in Early Childcare Settings: a Systematic Review.

A stronger understanding of the factors influencing implementation of interventions in community-based early childcare settings is needed. The purpose of this systematic review was to synthesize existing research on facilitators and barriers to implementation and sustainability of nutrition and physical activity interventions in early childcare settings targeting 2-5-year-old children, including considerations for equitable implementation. This review adhered to PRISMA 2020 guidelines. Peer-reviewed literature was searched in PubMed, EMBASE, CINAHL, ERIC, and PsycINFO databases up to September 2020. Primary research studies that examined facilitators and barriers (or related synonyms) to the implementation and sustainability of nutrition and physical activity interventions in early childcare settings were eligible for inclusion. The search yielded 8092 records that were screened by four analysts in Covidence software with a final review of 24 studies. Two independent reviewers conducted study selection, data extraction, and quality appraisal (Mixed Methods Appraisal Tool). A "best fit" framework was applied using the Consolidated Framework for Implementation Research (CFIR) constructs to code barriers and facilitators. The most salient constructs were (1) "Available Resources," which was composed of time, staffing, space, and staff trainings; (2) adaptability; and (3) compatibility, the latter two indicating that easily modifiable interventions facilitated a smoother "fit" and were more likely to be successful, given adequate site-level resources. Only nine (28%) reported the use of a theory, model, or framework to guide evaluation; six studies (24%) included factors related to sustainability; and nine studies (38%) conducted their interventions with low-income or minoritized groups. The findings point to the need for intervention evaluations examining nutrition and physical activity to more consistently consider (a) sustainability factors early on in design and adoption phases; (b) use of theory, model, or framework to guide evaluation; and (c) equity-related frameworks and considerations for how equitable implementation.

Effect of Mediterranean diet and Mediterranean diet plus calorie restriction on cognition, lifestyle, and cardiometabolic health: A randomized clinical trial.

A Mediterranean diet and intentional weight loss each positively affect cognitive functioning. Combining both could produce synergistic effects on cognition. The purpose of this study is to compare a Mediterranean diet lifestyle intervention with and without caloric restriction versus control on cognition, lifestyle, and cardiometabolic disease. In a three-arm trial conducted between 2017 and 2020 in Chicago, one hundred and eight-five, 55-85-year-old, predominately non-Hispanic black females with obesity were randomized (2:2:1) to an 8-month Mediterranean diet plus caloric restriction intervention, Mediterranean diet alone, or control. The primary outcome was change from baseline to post-intervention in cognitive composite scores: attention, information & processing; executive function; and learning, memory, & recognition. Secondary outcomes were weight, lifestyle and cardiometabolic markers. The 8-month Mediterranean diet interventions did not significantly affect cognition. Adherence to a Mediterranean diet improved more in the Mediterranean diet plus caloric restriction arm (mean [SE] score change, +6.3 [0.7] points) and Mediterranean diet alone arm (+4.8 [0.7] points) relative to controls (+0.6 [0.9] points). Mean weight loss was greater among the Mediterranean diet plus caloric restriction arm (-4.6 [0.6] kg) compared to the Mediterranean diet alone (-2.6 [0.6] kg) and control arms (-0.6 [0.7] kg). The interventions did not affect activity or cardiometabolic risk markers; although, fasting insulin did decline in the Mediterranean diet plus caloric restriction arm relative to the Mediterranean diet alone and control arms. A Mediterranean diet lifestyle intervention with and without caloric restriction did not significantly affect cognitive function compared to controls. The Mediterranean diet interventions, however, significantly affected diet quality and body weight.

Perceived factors that influence adoption, implementation and sustainability of an evidence-based intervention promoting healthful eating and physical activity in childcare centers in an urban area in the United States serving children from low-income, racially/ethnically diverse families.

Introduction: Early childcare centers offer optimal settings to provide healthy built environments where preschool age children spend a majority of their week. Many evidence-based interventions (EBIs) promoting healthful eating and physical activity for early childcare settings exist, but there is a limited understanding of how best to support adoption, implementation and sustainability in community settings. This study examined how early childcare teachers and administrators from Chicago-area childcare centers serving children from low-income, racially/ethnically diverse communities viewed an EBI called Hip to Health (H3), and the factors they perceived as relevant for EBI adoption, implementation, and sustainability. Methods: A multiple methods study including key informant interviews and a brief survey was conducted. Key informant interviews with teachers and administrators from childcare centers located in Chicago, IL were completed between December 2020 and May 2021. An interview guide and coding guide based on the Consolidated Framework for Implementation Research (CFIR) was developed. Interview transcripts were team coded in MAXQDA Qualitative Data Analysis software. Thematic analysis was used to identify findings specific to adoption, implementation, and sustainability. Participants were also asked to respond to survey measures about the acceptability, feasibility, and appropriateness of H3. Results: Overall, teachers (n = 20) and administrators (n = 16) agreed that H3 was acceptable, appropriate, and feasible. Low start-up costs, ease-of-use, adaptability, trialability, compatibility, and leadership engagement were important to EBI adoption. Timely and flexible training was critical to implementation. Participants noted sustainability was tied to low ongoing costs, access to ongoing support, and positive observable benefits for children and positive feedback from parents. Conclusions: These findings suggest that EBIs suitable for adoption, implementation, and sustainment in childcare centers serving racially/ethnically diverse, low-income families should be adaptable, easy to use, and low-cost (initial and ongoing). There is also some evidence from these findings of the heterogeneity that exists among childcare centers serving low-income families in that smaller, less resourced centers are often less aware of EBIs, and the preparation needed to implement EBIs. Future research should examine how to better support EBI dissemination and implementation to these settings.

Building research in diet and cognition (BRIDGE): Baseline characteristics of older obese African American adults in a randomized controlled trial to examine the effect of the Mediterranean diet with and without weight loss on cognitive functioning.

In the United States, >5.4 million people age 65 and older are affected by cognitive impairment and dementia, including Alzheimer's disease. African Americans are more likely than non-Hispanic whites to suffer from these disorders. Obesity is linked to accelerated age-related cognitive decline, and weight loss through caloric restriction is a potential strategy to prevent this cognitive impairment. Adherence to a healthful dietary pattern, such as the Mediterranean Diet (MedDiet), has also shown positive effects on reducing risk for dementia. African Americans are disproportionately affected by obesity and have less healthful diets than non-Hispanic whites. We present baseline characteristics from a three-arm randomized controlled trial that randomized 185 obese (BMI ≥ 30 kg/m2 and ≤ 50 kg/m2) healthy older adults (55-85 years of age) to: 1) Typical Diet Control (TDC); 2) MedDiet alone (MedDiet-A) intervention; or 3) MedDiet caloric restricted intervention to promote weight loss (MedDiet-WL). The majority of the sample was African American (91.4%) and female (85.9%). The two active interventions (MedDiet-A and MedDiet-WL) met once weekly for 8 months, and the TDC received weekly general health newsletters. Baseline data were collected between January 2017 and July 2019 in Chicago, IL. In our sample, closer adherence to a MedDiet pattern was associated with higher attention and information processing (AIP) and higher executive functioning (EF). Consistent with the literature, we saw that older participants performed more poorly on the cognitive assessments than younger participants, and women outperformed men across verbally mediated tasks, especially ones related to learning and memory.

Individual and Household-Level Factors Associated With Caregivers' Intention to Keep Their Child Enrolled in WIC.

OBJECTIVE: Identify factors associated with caregivers' intention to keep their child enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program until age 5 years. METHODS: Baseline data from a longitudinal questionnaire aiming to assess the impact of a statewide intervention to increase WIC retention in Illinois were analyzed in 2018. Data on sociodemographics and household characteristics were collected in 2015 from 174 caregiver/child dyads. Logistic regression was used to identify factors associated with caregivers' intention to keep their child enrolled in WIC until age 5 years (ie, intention). RESULTS: A total of 66% of caregivers stated they were very likely to keep their child enrolled in the WIC program. Breastfeeding and homeownership status were associated with 58% (P =.03) and 72% (P =.02) lower odds of intention among caregivers, respectively. CONCLUSIONS AND IMPLICATIONS: Significant inverse associations among breastfeeding, homeownership, and intention support the need for tailoring state-level WIC retention efforts to specific population characteristics and health behaviors.

The SHARED Project: A Novel Approach to Engaging African American Men to Address Lung Cancer Disparities.

Black men are disproportionately impacted by lung cancer morbidity and mortality. Low-dose helical computed tomography (LDCT) lung cancer screening has demonstrated benefits for reducing lung cancer deaths by identifying cancers at earlier, more treatable stages. Despite the known benefits, LDCT screening is underutilized in black men. Studies in racially heterogeneous populations have found correlations between screening behaviors and factors such as physician trust, physician referral, and a desire to reduce the uncertainty of not knowing if they had lung cancer; yet little is known about the factors that specifically contribute to screening behaviors in black men. Community engagement strategies are beneficial for understanding barriers to health-care engagement. One community engagement approach is the citizen scientist model. Citizen scientists are lay people who are trained in research methods; they have proven valuable in increasing communities' knowledge of the importance of healthy behaviors such as screening, awareness of research, building trust in research, and improving study design and ethics. This paper proposes an intervention, grounded in community-based participatory research approaches and social network theory, to engage black men as citizen scientists in an effort to increase lung cancer screening in black men. This mixed-methods intervention will examine the attitudes, behaviors, and beliefs of black men related to uptake of evidence-based lung cancer screening.
