Optimizing perinatal wellbeing in pregnancy with obesity: a clinical trial with a multi-component nutrition intervention for prevention of gestational diabetes and infant growth and neurodevelopment impairment

Pregnancy complicated by obesity represents an increased risk of unfavorable perinatal outcomes such as gestational diabetes mellitus (GDM), hypertensive disorders in pregnancy, preterm birth, and impaired fetal growth, among others. Obesity is associated with deficiencies of micronutrients, and pregnant women with obesity may have higher needs. The intrauterine environment in pregnancies complicated with obesity is characterized by inflammation and oxidative stress, where maternal nutrition and metabolic status have significant influence and are critical in maternal health and in fetal programming of health in the offspring later in life. Comprehensive lifestyle interventions, including intensive nutrition care, are associated with a lower risk of adverse perinatal outcomes. Routine supplementation during pregnancy includes folic acid and iron; other nutrient supplementation is recommended for high-risk women or women in low-middle income countries. This study is an open label randomized clinical trial of parallel groups (UMIN Clinical Trials Registry: UMIN000052753, https://center6.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000060194) to evaluate the effect of an intensive nutrition therapy and nutrient supplementation intervention (folic acid, iron, vitamin D, omega 3 fatty acids, myo-inositol and micronutrients) in pregnant women with obesity on the prevention of GDM, other perinatal outcomes, maternal and newborn nutritional status, and infant growth, adiposity, and neurodevelopment compared to usual care. Given the absence of established nutritional guidelines for managing obesity during pregnancy, there is a pressing need to develop and implement new nutritional programs to enhance perinatal outcomes.

The use of eHealth and health coaching in postnatal diabetes prevention, in women with history of gestational diabetes

This literature review explores the role of eHealth and health coaching in assisting prevention of type 2 diabetes in women with history of gestational diabetes mellitus (GDM). The integration of electronic health (eHealth) and mobile health (mHealth) technologies, including telemedicine, smartphone apps, and mixed-method approaches, has emerged as a crucial strategy in healthcare delivery. These technologies address postnatal barriers such as lack of support, time constraints, and childcare issues, enhancing accessibility to diabetes prevention interventions. The review presents evidence from various studies, including randomized controlled trials and ongoing research projects, indicating positive impacts on engagement, adherence, and follow-up rates when utilizing remote interventions through smartphone apps and health coaching. Notably, the use of telemedicine during the COVID-19 pandemic has further underscored the potential benefits of delivering care remotely. The focus on postnatal diabetes prevention in women with a history of GDM is particularly pertinent, given the increased risk of developing type 2 diabetes. The inclusion of partners and families in interventions, highlights a holistic approach to promoting a healthy lifestyle. While the results are promising, the review acknowledges the inconclusive nature of current evidence, emphasizing the need for further research to establish the long-term efficacy and acceptance of these interventions. Continued efforts to refine these strategies and expand research will contribute to a better understanding of their impact, ultimately paving the way for targeted and effective diabetes prevention in this high-risk population of women with a history of GDM.

Mapping Lifestyle Interventions for Gestational Diabetes Prevention: A Scoping Review.

The purpose of this study was to conduct a scoping review to map intervention, sample, and physiologic measurement characteristics of lifestyle interventions for gestational diabetes mellitus (GDM) prevention. A total of 19 studies met selection criteria from 405 articles screened (PubMed, Web of Science). No studies were US-based (47% multi-site), and all were delivered in clinical settings. The most targeted nutrition components were low carbohydrate intake (sugar rich foods/added sugars, low glycemic index), low fat intake (mainly low-fat meat, dairy, and saturated fat), and increased fruits and vegetables. Many studies promoted 150min/week moderate-intensity physical activity. Only two studies provided supervised physical activity sessions. Dietitians and nurses were the most common implementers. Samples were characterized as adults with obesity (mean age 31yr, BMI 31kg/m2). Asian populations were predominantly studied. Four studies used theoretical frameworks (75% of which used Social Cognitive Theory). GDM diagnostic criteria set forth by the American Diabetes Association were the most widely used. Insulin sensitivity was commonly assessed via fasting indices. There was a lack of multi-disciplinary, multi-level, and theory-based lifestyle interventions for reducing GDM risk. Addressing these gaps and prioritizing high-risk populations in the US with measurement of traditional and novel biomarkers will advance the field.

Perceptions of diabetes risk and prevention in Nairobi, Kenya: A qualitative and theory of change development study.

Type 2 diabetes is increasing in Kenya, especially in urban settings, and prevention interventions based on local evidence and context are urgently needed. Therefore, this study aimed to explore diabetes risk and co-create a diabetes prevention theory of change in two socioeconomically distinct communities to inform future diabetes prevention interventions. In-depth interviews were conducted with middle-aged residents in two communities in Nairobi (one low-income (n = 15), one middle-income (n = 14)), and thematically analysed. The theory of change for diabetes prevention was informed by analysis of the in-depth interviews and the Behaviour Change Wheel framework, and reviewed by a sub-set (n = 13) of interviewees. The key factors that influenced diabetes preventive practices in both communities included knowledge and skills for diabetes prevention, understanding of the benefits/consequences of (un)healthy lifestyle, social influences (e.g., upbringing, societal perceptions), and environmental contexts (e.g., access to (un)healthy foods and physical activity facilities). The proposed strategies for diabetes prevention included: increasing knowledge and understanding about diabetes risk and preventive measures particularly in the low-income community; supporting lifestyle modification (e.g., upskilling, goal setting, action planning) in both communities; identifying people at high risk of diabetes through screening in both communities; and creating social and physical environments for lifestyle modification (e.g., positive social influences on healthy living, access to healthy foods and physical activity infrastructure) particularly in the low-income community. Residents from both communities agreed that the strategies were broadly feasible for diabetes prevention but proposed the addition of door-to-door campaigns and community theatre for health education. However, residents from the low-income community were concerned about the lack of government prioritisation for implementing population-level interventions, e.g., improving access to healthy foods and physical activity facilities/infrastructure. Diabetes prevention initiatives in Kenya should involve multicomponent interventions for lifestyle modification including increasing education and upskilling at individual level; promoting social and physical environments that support healthy living at population level; and are particularly needed in low-income communities.

Diet and Physical Activity by Prediabetes Status Among U.S. Adolescents: National Health and Nutrition Examination Survey, 2007-2018.

Background: Prediabetes among adolescents is on the rise, yet it is unclear if modifiable risk factors vary by prediabetes status. Methods: This study examined associations between diet (primary objective) and physical activity (secondary objective) by prediabetes status among U.S. adolescents (12-19 years) who participated in the National Health and Nutrition Examination Survey from 2007-2018. Differences in Healthy Eating Index (HEI)-2015-2020 scores (total and 13 component scores), nutrients of public health concern, and physical activity were examined by prediabetes status (no prediabetes vs. prediabetes). Results: Adolescents (n = 2,487) with prediabetes had significantly lower whole grains component scores and intakes of vitamin D, phosphorus, and potassium (all p < .05), than adolescents without prediabetes. Physical activity levels were not optimal for either group, there were no differences by prediabetes status (n = 2,188). Conclusion: Diabetes prevention interventions for adolescents are needed and should promote a healthy diet target and encourage physical activity.

State health departments leverage pharmacy partnerships across the nation to advance diabetes care initiatives

BackgroundIn 2018, the Centers for Disease Control and Prevention (CDC)’s Division of Diabetes Translation (DDT) initiated a 5-year cooperative agreement funding opportunity with departments of health in every state and the District of Columbia. The funded recipients pursued activities that strengthened diabetes management and type 2 diabetes prevention interventions within their jurisdictions. An option to involve the pharmacy sector in their diabetes-related interventions was available. ObjectivesThis research aims to understand who public health departments partnered with in the pharmacy sector and identify the types of activities pursued together to expand access to diabetes-related interventions. MethodsA review of annual work plans and progress reports submitted to CDC by recipients during the first 4 years of the funding cycle was conducted. Descriptions of work conducted in partnership with pharmacies, pharmacists, or pharmacy organizations were flagged for review, coding, and analysis. ResultsOf the 51 public health department recipients, 48 collaborated with pharmacy partners within their jurisdictions. Activities were developed and carried out in ways that utilized the pharmacy workforce to support public health diabetes initiatives, such as the development and delivery of diabetes self-management education and support and type 2 diabetes prevention programs in pharmacies (68.8%), delivery of diabetes-related training for the pharmacy workforce (91.7%), and support of billing and sustainability efforts for pharmacy-based diabetes services (52.1%). ConclusionState public health department diabetes program personnel cultivated productive relationships with a variety of members of the pharmacy workforce. Through these partnerships, they leveraged one another's resources, expertise, and mutual determination to prepare and carry out diabetes-related interventions within their states. This document provides pharmacists and pharmacy decision-makers with foundational knowledge that can lead to increased engagement with public health partners to expand diabetes management and prevention services in pharmacy settings.

Knowledge, perceptions and practices towards diabetes risk in sub-Saharan Africa: a mixed-methods scoping review.

To synthesise current evidence on knowledge, perceptions and practices towards type 2 diabetes risk in sub-Saharan Africa. Mixed-methods scoping review, which included 101 studies (seventy-three quantitative, twenty qualitative and eight mixed methods) from seven electronic databases. Sub-Saharan Africa, 2000-2023. Men and women without diabetes with mean ages ranging from 20 to 63 years. The majority of participants in most studies knew the three main diabetes modifiable risk factors - excess weight, unhealthy diet and physical inactivity. However, most people with excess weight in almost all studies underestimated their weight. Further, the self-described ideal body weight was between midpoint of normal weight and the upper limits of overweight in most quantitative studies and was described as not too skinny but not too fat in qualitative studies. In the majority of studies, participants reported low engagement in weight control, high regular sugar intake, and low regular fruit and vegetable intake but moderate to high engagement in physical activity. Barriers to reducing diabetes risk were social (e.g. societal perceptions promoting weight gain) and environmental (e.g. limited affordability of healthy foods, high accessibility of Western diets and lack of physical activity facilities). There is a need for multicomponent type 2 diabetes prevention interventions that increase knowledge of identifying diabetes risk (e.g. what constitutes excess weight) and create social and physical environments that support healthy lifestyles (e.g. societal perceptions that promote healthy living, increased availability and affordability of healthy foods and physical activity facilities).

Sex Differences in Diet and Physical Activity Behaviors Among Racial/Ethnic Minority Adolescents with High Metabolic Risk.

Certain dietary and physical activity (PA) behaviors may differentially predispose male and female adolescents to obesity and diabetes; however, sex differences in dietary and PA behaviors and in factors that impact these behaviors (e.g., self-efficacy, social support) in this population remain unknown. Using data from a community-based adolescent diabetes prevention intervention conducted in East Harlem in New York City, we examined sex differences in baseline characteristics including clinical measurements, lifestyle behaviors, and behavioral determinants. Among 147 overweight/obese adolescents aged 13-19years, 61.9% were girls, 69.7% were of Hispanic ethnicity, 24.8% were non-Hispanic Black, and 60.5% were diagnosed with prediabetes. Boys had higher metabolic risk scores than girls (3.8 vs. 3.3, p = 0.002) despite girls reporting more perceived barriers to healthy eating and PA. Boys reported doing more moderate to vigorous PA but also had more sedentary behaviors than girls. Boys reported higher self-efficacy and more peer support for PA. Girls reported more depressive symptoms and were more likely to compare their body images to those in magazines/social media. Overall, among a sample of urban adolescents with high metabolic risk, we found significant sex differences in many dietary and PA behaviors and related factors, which could be used to inform tailored strategies for weight management to reduce cardiometabolic risk among youth from similar high-risk populations.

Weight loss maintenance following an augmented intervention for early slow weight loss responders: An adaptive trial.

Early slow weight loss during treatment is associated with less weight loss overall. The impact of an augmented intervention designed for early slow weight loss responders compared with a standard diabetes prevention intervention was evaluated following 12 months of treatment and 6 months of no contact. The impact of standard vs. augmented intervention sequences on weight and glycemia also was determined. Adults were ≥21 years old with overweight or obesity and prediabetes (n = 174). Slow responders were stratified to augmented treatment if they failed to achieve >2.5% weight loss (%WL) at Week 5. Matched within-sex pairs of participants were created based on %WL at Month 5 following the intensive intervention phase, and each person within the pair was randomly assigned to treatment for Months 5-12 during the extended intervention phase. Both 12-month interventions included a ≥7%WL goal. Mean 12-month %WL was 5.29% (95% CI: 4.27%-6.31%; P < .0001) and 18-month %WL was 3.34% (95% CI: 2.01%-4.66%; P < .0001) overall. %WL was greater for the standard (9.55%) than the augmented (4.0%) intervention (P = .0001); no differences occurred in weight regain between early and slow responders (P = .9476). No differences occurred in mean %WL at 12 months between the standard and augmented groups after controlling for %WL at Week 5 and sex (P = .23) nor in the change in glycemia (all P > .05). WL following the first month of treatment predicted 12- and 18-month WL success regardless of intervention sequence; however, even early slow responders achieved significant WL during treatment. Further research is needed to support effective WL maintenance for people with prediabetes.

Feasibility and Acceptability of the Project Faith Influencing Transformation Intervention in Faith-Based Settings.

African Americans (AAs) are disproportionately burdened with diabetes and prediabetes. Predominately AA churches may be optimal settings for reaching AAs at greatest diabetes risk, along with related morbidities and mortalities. The current study used the RE-AIM framework to qualitatively examine the feasibility, acceptability, and satisfaction with the Project Faith Influencing Transformation (FIT) intervention, a diabetes risk reduction intervention in AA churches. Participants were (N = 21) church and community members who also participated in the larger Project FIT intervention and were primarily female, with an average age of 60 years (SD = 11.1). Participants completed a brief survey and focus group discussion. Participants discussed intervention effectiveness in changing health behaviors and outcomes, with high rates of adoption, acceptability, and satisfaction across churches that conducted the intervention. Participants also discussed outreach to members of the broader community, the role of the pastor, and challenges to intervention implementation and maintenance-tailored strategies to improve intervention effectiveness are discussed. Given the significant diabetes disparities that exist for AAs, it is imperative to continue to investigate best practices for reaching communities served by churches with sustainable, relevant health programming. This study has the potential to inform more effective, tailored diabetes prevention interventions for high-risk AAs in faith-based settings.

Social Media-Delivered Lifestyle Interventions Among Individuals Living with Diabetes and Prediabetes: A Scoping Review.

There is a lack of synthesized evidence on social media-delivered lifestyle interventions for managing and preventing diabetes. This scoping review aims to evaluate recently reported lifestyle interventions delivered on social media for individuals with diabetes and prediabetes. Twelve studies were included in this review. A team of multidisciplinary healthcare professionals coordinated most interventions, half of which lasted for 6months, and used a combination of videos, texts, images or audio to deliver the educational materials. The glycosylated hemoglobin (HbA1c) level improved in most of the studies, followed by diabetes self-care and fasting plasma glucose. The dietary intakes were only assessed in two interventions among the individuals with prediabetes and showed promising improvements. This scoping review provides a holistic overview of the recent designs of lifestyle interventions for diabetes management and prevention on social media. This is essential for various healthcare professionals and stakeholders to formulate and implement population-based, cost-effective interventions in combating diabetes using social media.

Increasing the reach of evidence-based interventions for weight management and diabetes prevention among Medicaid patients: study protocol for a pilot Sequential Multiple Assignment Randomised Trial

IntroductionOver 40% of US adults meet criteria for obesity, a major risk factor for chronic disease. Obesity disproportionately impacts populations that have been historically marginalised (eg, low socioeconomic status, rural,...

Preventing diabetes in Latino families: A protocol for a randomized control trial

BackgroundLatino families are disproportionately affected by type 2 diabetes (T2D) and lifestyle intervention is the first-line approach for preventing T2D. The purpose of this study is to test the efficacy of a culturally-grounded lifestyle intervention that prioritizes health promotion and diabetes prevention for Latino families. The intervention is guided by a novel Family Diabetes Prevention Model, leveraging the family processes of engagement, empowerment, resilience, and cohesion to orient the family system towards health. MethodLatino families (N = 132) will be recruited and assessed for glucose tolerance as measured by an Oral Glucose Tolerance Test (OGTT) and General and Weight-Specific Quality of Life (QoL) at baseline, four months, and 12 months. All members of the household age 10 and over will be invited to participate. Families will be randomized to the intervention group or a control group (2:1). The 16-week intervention includes weekly nutrition and wellness classes delivered by bilingual, bicultural Registered Dietitians and community health educators at a local YMCA along with two days/week of supervised physical activity classes and a third day of unsupervised physical activity. Control families will meet with a physician and a Registered Dietitian to discuss the results of their metabolic testing and recommend lifestyle changes. We will test the efficacy of a family-focused diabetes prevention intervention for improving glucose tolerance and increasing QoL and test for mediators and moderators of long-term changes. ConclusionThis study will provide much needed data on the efficacy of a family-focused Diabetes Prevention Program among high-risk Latino families.

Risk Factors for Progression to Type 2 Diabetes in a Pediatric Prediabetes Clinic Population.

Pediatric type 2 diabetes (T2D) is increasing in prevalence, yet it is unclear what definition of pediatric prediabetes predicts progression to T2D. Strategies are needed to better identify at risk individuals who could benefit from early intervention. Retrospective chart review of a pediatric prediabetes clinic over 7 years. Inclusion criteria include hemoglobin A1c (HbA1C) and ≥1 glucose from oral glucose tolerance test. Exclusion criteria include type 1 diabetes, maturity onset diabetes of the young, or T2D on initial visit. A total of 552 patients were included, 6.5% (n = 36) progressed to T2D over 2.4 ± 1.5 years. At initial visit, T2D progressors had a higher body mass index (38.6 ± 6.5 vs 34.2 ± 8.4 kg/m2, P = .002), HbA1C (6.0 ± 0.3%, vs 5.7± 0.3, P < .001), 2-hour glucose (141 ± 28 vs 114 ± 29 mg/dL, P < .001), and C-peptide (4.8 vs 3.6 ng/mL, P = .001). Fasting glucose was not significantly different. In a multivariable model, male sex (hazard ratio [HR], 2.4; P = .012), initial visit HbA1C (HR, 1.3 per 0.1% increase; P < .001), and 2-hour glucose level (HR, 1.2 per 10 mg/dL increase; P = .014) were all predictive of T2D progression. Patients who progressed to T2D had an increase in body mass index of 4.2 kg/m2 and children consistently taking metformin took longer to progress (43 ± 21 vs 26 ± 16 months; P = .016). A total of 6.5% of patients with prediabetes developed T2D over a 7-year period. Initial visit laboratory values and weight trajectory may allow for risk stratification, whereas fasting plasma glucose is less helpful. Weight stabilization and metformin therapy could be important interventions for diabetes prevention in children.

[Application progress of implementation research on diabetes management].

Diabetes is one of the most important non-communicable chronic diseases. Although a large amount of clinical evidence on the effectiveness of diabetes prevention and treatment interventions has been established, the current quality of care and results are still insufficient. Implementation Research can bridge the gap between research and practice. Implementation Research on diabetes management can clarify what is effective and what is ineffective in management, and promote the transformation of complex, multi-component interventions into medical practice faster and more effectively. This paper reviews the main research contents and application of implementation research of diabetes management at home and abroad, aiming to provide reference for related research and promote the application of implementation research in diabetes management in China.

FRI587 Risks For Type 2 Diabetes Progression In A Pediatric Prediabetes Clinic Population

Abstract Disclosure: N.A. Belsky: None. J. Tamaroff: None. A.H. Shoemaker: None. Background: Pediatric type 2 diabetes (T2D) is increasing in prevalence, yet the pathophysiology and disease progression is less understood than in adults. It is unclear what definition of pediatric prediabetes predicts progression to T2D or long-term morbidity. Strategies are needed to better identify at risk individuals who could benefit from close follow up and early intervention. This study utilized a Pediatric Prediabetes Clinic to assess what factors may be associated with increased risk of progression to T2D in children over time. Methods: We conducted a retrospective chart review of the initial visit for all children referred to the clinic over 7 years. Inclusion criteria included hemoglobin A1c and ≥1 glucose result from an oral glucose tolerance test. Children with type 1 diabetes, MODY, or T2D on initial visit were excluded. Patients were assigned to either the T2D progression or non-progression group for further analysis based on 2022 ADA criteria. Additional information was manually charted for the T2D progression group from each visit from initial presentation through diagnosis of T2D. Results: 552 patients were included, 6.5% (n= 36) progressed to T2D over 2.4 ± 1.5 years. At the initial visit, T2D progressors had a higher BMI (mean difference 4.4 kg/m2, p = 0.002) and weight (mean difference 14.2 kg, p = 0.004). Initial visit HbA1c (5.7± 0.3 vs. 6.0±0.3%, p &amp;lt;0.001), 2h glucose (141±28 vs. 114±2mg/dL, p &amp;lt;0.001) and fasting c-peptide (4.8±2.1 vs. 3.6±2.0 ng/mL, p = 0.001) were also higher in the T2D progression group. On a fasting lipid panel, triglycerides (138±64 vs. 109±59 mg/dL, p = 0.015) were higher and HDL was lower (38±5 vs. 41±9 mg/dL, p = 0.003) in T2D progressors. Fasting plasma glucose was not significantly different between groups. Mean age at T2D diagnosis was 14.9 years (range 9.9 – 18.3 years). In a multivariable model, male sex (HR 2.4, p = 0.012), initial visit HbA1c (HR 1.3 per 0.1% increase, p &amp;lt;0.001), and 2-hour glucose level (HR 1.2 per 10 mg/dL increase, p = 0.014) were all predictive of increased likelihood of progression over time, while age did not reach significance (HR 0.9, p = 0.05). On average, patients who progressed to T2D had an increase in BMI of 4.2 kg/m2 from initial visit to time of T2D diagnosis and children consistently taking metformin took longer to progress (43 ± 21 vs. 26 ± 16 months, p= 0.016). Discussion: Overall, few patients with prediabetes developed T2D over the 7-year period, highlighting the importance of identifying which patients should receive early intervention and close follow-up. Initial visit laboratory values (particularly HbA1c and non-fasting glucose) and weight trajectory may allow for risk stratification, while fasting plasma glucose is less helpful. Preventing further worsening of obesity and metformin therapy could be important interventions for diabetes prevention in children. Presentation: Friday, June 16, 2023

The Effectiveness of Metformin in Diabetes Prevention: A Systematic Review and Meta-Analysis.

Diabetes mellitus is a growing global health concern, and prevention strategies play a crucial role in reducing its burden. Metformin has been widely studied as a potential intervention for diabetes prevention, but its overall effectiveness and impact on various populations remain unclear. This study aims to provide a comprehensive synthesis of the available evidence on the effectiveness of metformin in diabetes prevention. A systematic search was conducted in PubMed, Scopus, ScienceDirect, and Google Scholar for articles published from inception to June 2023. The reference lists of the included studies were also searched to retrieve possible additional studies. Any quantitative data were analyzed using Review Manager 5.4. A P-value of 0.05 was adopted as the significance threshold. Our analysis included 17 studies with a total sample size of 30,474. Our meta-analysis included two key analyses. First, the meta-analysis evaluating the effects of metformin on prediabetes demonstrated a significant reduction in the risk of progressing to type 2 diabetes mellitus (T2DM). The pooled odds ratio (OR) was 0.65 (95% confidence interval [CI] 0.53-0.80), indicating a 35% lower odds of developing T2DM among individuals with prediabetes who received metformin interventions compared to control groups. Secondly, the meta-analysis assessing the efficacy of metformin interventions in preventing T2DM yielded a significant reduction in the risk of developing the disease. The pooled risk ratio was 0.58 (95% CI 0.44-0.77), indicating a 42% lower risk of developing T2DM in individuals receiving metformin interventions compared to those in non-metformin intervention groups. These findings provide strong evidence for the effectiveness of metformin in preventing the progression of prediabetes to T2DM and reducing the overall incidence of the disease. The review demonstrated that metformin is effective in reducing the risk of developing diabetes mellitus among individuals at risk for the disease. The findings highlight the potential of metformin as a valuable intervention for diabetes prevention, particularly in high-risk populations.

Secondary analysis of a randomized trial testing community health educator interventions for diabetes prevention among refugees with depression: effects on nutrition, physical activity and sleep

BackgroundRefugees have high levels of psychological distress that hamper lifestyle change efforts. We previously reported that community health educator (CHE) diabetes prevention interventions decreased HbA1c and depressive symptoms among Cambodian-American refugees with depression; this paper reports health behavior outcomes of those interventions.MethodsParticipants were aged 35–75, Khmer speaking, at risk for diabetes, and met study criteria for likely depression by either a) antidepressant medication and/or b) prolonged elevated depressive symptoms. Participants were randomized to one of three CHE interventions: 1) lifestyle intervention called Eat, Walk, Sleep (EWS), 2) EWS plus medication therapy management with a pharmacist/CHE team (EWS + MTM), or, 3) social services (SS; control). Physical activity and sleep were measured with 7 days of actigraphy. Nutrition was measured as carbohydrates as reported in a culturally tailored food frequency questionnaire. Assessments were at baseline, end point (12 months), and follow-up (15 months).ResultsThe n = 188 participants were 78% female, average age of 55 years, half had a household income < $20,000, and modal education was 7.0 years. Individuals in the two treatment groups that received the EWS intervention significantly increased their brown rice consumption (p < .001, Cohen’s d = 0.76) and their moderate-to-vigorous activity (p = .039, d = 0.32). No intervention changed sleep duration, timing, efficiency or wake after sleep onset. Across groups, individuals who increased brown rice consumption, increased vigorous activity and decreased total sleep time variability showed decreased HbA1c, with small effect sizes.ConclusionsCHEs may improve nutrition and physical activity in refugees with depression but more intensive interventions may be required to impact sleep. Improvements in all three behaviors appear to be associated with HbA1c loweringTrial registrationClinicalTrials.gov identifier NCT02502929.

Socio-economic factors, mood, primary care utilization, and quality of life as predictors of intervention cessation and chronic stress in a type 2 diabetes prevention intervention (PREVIEW Study)

BackgroundSedentary lifestyle and unhealthy diet combined with overweight are risk factors for type 2 diabetes (T2D). Lifestyle interventions with weight-loss are effective in T2D-prevention, but unsuccessful completion and chronic stress may hinder efficacy. Determinants of chronic stress and premature cessation at the start of the 3-year PREVIEW study were examined.MethodsBaseline Quality of Life (QoL), social support, primary care utilization, and mood were examined as predictors of intervention cessation and chronic stress for participants aged 25 to 70 with prediabetes (n = 2,220). Moderating effects of sex and socio-economic status (SES) and independence of predictor variables of BMI were tested.ResultsParticipants with children, women, and higher SES quitted intervention earlier than those without children, lower SES, and men. Lower QoL, lack of family support, and primary care utilization were associated with cessation. Lower QoL and higher mood disturbances were associated with chronic stress. Predictor variables were independent (p ≤ .001) from BMI, but moderated by sex and SES.ConclusionsPolicy-based strategy in public health should consider how preventive interventions may better accommodate different individual states and life situations, which could influence intervention completion. Intervention designs should enable in-built flexibility in delivery enabling response to individual needs.Trial registrationClinicalTrials.gov Identifier: NCT01777893.
