A pilot study titled "A Virtual Cardiometabolic Health Program for African Immigrants (The Afro-DPP Program) will be conducted to address the cardiometabolic of community-dwelling African immigrants who have multiple cardiometabolic risk factors including hypertension, Type 2 Diabetes, high cholesterol, and overweight/obesity. The proposed study will recruit a total of 60 participants and will use a non-equivalent control group design to test the effectiveness of the intervention at two African churches in the Baltimore, Washington, D.C. area. The two churches will be randomly assigned to the intervention or delayed intervention group. At the end of a 6-month follow-up period, the control church will receive the intervention (delayed control group). All participants will receive a Bluetooth-enabled digital scale (Omron Model: BCM-500) that measures body composition including Body Weight, Body Fat percentage, Visceral Fat, Skeletal Muscle percentage, Resting Metabolism and Body Mass Index. A Bluetooth-enabled blood pressure monitor (Omron Model: BP7250) will also be distributed to all participants. All participants will download the Omron Connect app which will allow the participants to sync participants' blood pressure readings and body composition readings into the app. The research team will access these readings to monitor study outcomes and participants progress during the follow-up period.

NCT05745441
Obesity and its metabolic complications are leading causes of global morbidity and mortality. Evidence is mounting that inappropriate timing of food intake contributes to obesity. Specifically, late eating is associated with greater weight gain and metabolic syndrome. However, the mechanism by which late eating harms metabolism is not fully understood but may be related to mis-timing of food intake in relation to the body's endogenous circadian rhythm. Conversely, harmonization of eating timing with endogenous circadian rhythm may optimize metabolic health. In this study the investigators will use gold-standard methods of characterizing circadian rhythm in humans to examine the metabolic impacts food timing relative to endogenous circadian rhythm.

The control group (CON) will perform the exercise program at home/outdoors without any monitoring or follow up.
NCT07229781
The purpose of this research study is to determine if a healthy Mediterranean diet containing one medium potato/day has equivalent or non-different effects on risk factors for type 2 diabetes and heart disease compared to a healthy Mediterranean diet without potatoes in adults with prediabetes. Participants will be randomly assigned to one of the test diets and be asked to consume this diet for 12 weeks (84 days). Testing will be conducted at the beginning and end of the study.
NCT07286747
The goal of this clinical trial is to prevent the change from prediabetes (a pre-stage of type 2 diabetes mellitus (T2DM)) to T2DM in participants with prediabetes using oral CIR-NA (a nicotinic acid formulation that is designed to be released after reaching the ileum) which targeted the gut microbiota. The main questions it aims to answer are: 1. Is CIR-NA effective and does it prevent the change from prediabetes to T2DM? 2. Is the safety of CIR-NA that was observed in the Phase I clinical trial confirmed in subjects with prediabetes? Researchers will compare CIR-NA to a placebo (a look-alike substance that contains no drug) in terms of an extended safety evaluation including safety laboratory assessments, physical examination, vital signs and 12-lead ECG. Participants will: Take CIR-NA or a placebo every day for 26-weeks. Visit the clinic at week 1 and subsequently once every 4 weeks for checkups and tests. Receive standardized lifestyle recommendations regarding nutrition and physical activity during the intervention.

Adapt the Regulation of Cues (ROC) treatment program for Latinas to see if it can treat prediabetes and prevent developing of Type 2 Diabetes and reduce weight.
NCT05119179
This project uses both transcriptomic- and genomic-level data to identify mechanisms of individual responses to glucagon-like peptide-1 (GLP-1) in Mexican-Americans with prediabetes. The GLP-1 hormone is essential for glucose reduction, weight loss, cardiovascular risk reduction, and renal protection. Newly discovered mechanisms will illuminate causal links between disease genotype and phenotype, which may ultimately guide personalized therapeutic approaches for type 2 diabetes, prediabetes, obesity, cardiovascular disease, renal disease, and other related diseases.
NCT07462078
Diabetes mellitus is a major global health challenge, with type 2 diabetes (T2DM) accounting for nearly 90% of all cases worldwide. In Egypt, diabetes prevalence among adults is high (15.2%), with approximately 10.9 million people currently affected and projections estimating a rise to 13 million by 2030, placing Egypt among the top ten countries worldwide for diabetes prevalence. Alarmingly, a large proportion of diabetes and most prediabetes cases remain undiagnosed. Prediabetes is a common, asymptomatic, and reversible condition that precedes T2DM and is characterized by elevated blood glucose levels not meeting diagnostic thresholds for diabetes. Diagnostic criteria include impaired fasting plasma glucose, impaired glucose tolerance, and elevated HbA1c. Globally, prediabetes affects nearly one-third of adults, and in Egypt its prevalence ranges from 21-24% in community and occupational settings. Individuals with prediabetes face a significantly increased risk of progressing to T2DM, cardiovascular disease, and mortality, with up to 70% developing diabetes during their lifetime if left untreated. Early identification of prediabetes is essential and cost-effective. Non-invasive screening tools such as the Finnish Diabetes Risk Score (FINDRISC) provide a practical method for identifying high-risk individuals, who can then undergo confirmatory blood testing. Lifestyle modification is the cornerstone of prediabetes management and is more effective than pharmacological therapy alone. Evidence shows that modest weight loss, increased physical activity, and dietary improvements significantly reduce diabetes incidence and improve glycemic parameters. Structured lifestyle programs, particularly the Diabetes Prevention Program (DPP), have demonstrated substantial benefits through achieving at least 7% weight loss and 150 minutes of moderate physical activity per week. Establishing nationwide screening and lifestyle intervention programs in Egypt is strongly recommended to reduce the burden of diabetes. Local implementation initiatives provide critical evidence to support the scalability and effectiveness of such preventive strategies.
NCT07455435
This research explores how wearable glucose monitors might help prevent type 2 diabetes in people at risk of developing the disease. Type 2 diabetes affects more than 1 in 10 Americans and costs the nation $327 billion annually. Even though it's clear that physical activity helps prevent diabetes, and that even small increases in daily movement (like walking or climbing stairs) can significantly lower risk, getting people to be more active remains challenging. A device called a continuous glucose monitor (CGM) might offer a solution. This small wearable sensor tracks blood sugar levels throughout the day and sends the information to a phone or watch. While these devices are already helping people who have diabetes manage their condition better, the investigators want to study if wearing a CGM may encourage at-risk people to become more physically active. The investigators are particularly interested in seeing whether real-time blood sugar data plus education can be an effective tool to promote lifestyle changes, such as walk more steps every day. The study also aims to examine whether using a CGM helps stabilize blood sugar levels in prediabetes. The researchers believe that even short-term use of these monitors could lead to increased physical activity and more stable blood sugar levels, potentially helping prevent diabetes development.
NCT06252038
The purpose of this randomized controlled trial is to compare the effectiveness of Cooperative Extension implementing two delivery methods (group video vs. self-directed) and participant recruitment strategies of the National Diabetes Prevention Program (NDPP) to adults in rural communities. Exploratory assessments of implementation facilitators and barriers will be completed to determine strategies that may impact intervention effectiveness and that may support or impede the implementation, dissemination, and effectiveness of Cooperative Extension to deliver the NDPP to prediabetic adults in rural areas.
NCT07440147
Night shift work is associated with an increased risk of obesity, insulin resistance, and cardiometabolic disorders, largely due to circadian misalignment, disrupted sleep, and altered eating patterns. These behavioral and physiological disturbances impair glucose metabolism and are further influenced by the gut microbiota. In particular, the bacterium Akkermansia muciniphila has been linked to improved metabolic health, including enhanced insulin sensitivity, lipid regulation, and maintenance of intestinal barrier integrity. Berberine, a bioactive plant-derived compound, has demonstrated metabolic benefits, including upregulation of A. muciniphila, improvement of insulin sensitivity, and modulation of lipid metabolism. Together, these complementary mechanisms suggest that combined A. muciniphila supplementation and berberine administration may synergistically improve metabolic health in shift workers by targeting gut microbiota composition and circadian-regulated metabolic pathways. Based on this rationale, a double-blind, randomized, placebo-controlled, crossover study is being conducted in 200 night-shift workers from healthcare and industrial sectors in Austria and Denmark. Participants are stratified by age, sex, and work sector and randomly assigned to intervention sequences. Each participant receives either the combined supplement or placebo for 12 weeks, followed by a four-week washout, after which the alternate intervention is administered for another 12 weeks, with a total participation of 28 weeks. Assessments are performed at four study visits and include anthropometry, body composition, blood pressure, and collection of blood, urine, and feces. Participants complete validated questionnaires on dietary intake, lifestyle, work schedules, and general health to monitor behavioral patterns throughout the study. Dietary intake is recorded for four days prior to each sampling visit in consideration of shift schedules. Sleep duration and quality are monitored via diaries and actigraphy and aligned with dietary records. Circadian variation is minimized by standardizing sampling times and implementing a fasting and synchronization period prior to visits. The primary outcome is insulin sensitivity, measured by HOMA-IR. Secondary exploratory outcomes include gut microbiota composition and diversity, biomarkers of intestinal permeability and inflammation, lipid profiles, body composition, sleep quality, and dietary behavior. These measures collectively provide a comprehensive evaluation of the metabolic, microbiome, and circadian effects of combined A. muciniphila and berberine supplementation in night-shift workers.

Examination of individuals with prediabetes and established diabetes for early signs of diabetic retinopathy.
NCT06976307
This is a sub-study to NCT04745572 to include a new cohort of participants with disabilities. This 16-week study will use an experimental approach called the Sequential Multiple Assignment Randomized Trial to help determine which combination and sequence of weight loss program features are most effective in people who are at risk for type 2 diabetes. Participants in the study will be initially randomized to consume either a high or reduced carbohydrate diet. After 4 weeks, participants will be identified as Responders (greater than or equal to 2.5% weight loss) or Non-Responders (less than 2.5% weight loss). Responders will continue with their initial randomized group for the remainder of the trial. Non-responders will be re-randomized to 2nd stage interventions of either including additional exercise counseling and training or beginning a time restricted eating protocol for the remainder of the trial.
NCT07338552
Individuals with prediabetes are at high risk for developing type 2 diabetes mellitus (T2DM) and are therefore prone to serious complications such as stroke, kidney failure, blindness, and lower-limb amputation. Prediabetes can be reversed, and lifestyle modification is considered the most effective intervention for diabetes prevention. However, it is difficult for individuals with prediabetes to maintain long-term healthy lifestyle changes owing to psychological burnout and poor adherence during daily self-management. We developed a novel virtual health management community (VHMC) model based on group interaction management. The purpose of this study is to evaluate whether a virtual health management community-based intervention can improve glycemic control and related health outcomes in adults with prediabetes. Participants in the intervention group will receive lifestyle management support through a virtual health management community, including health education, lifestyle guidance, and group-based interaction delivered via a digital platform. Participants will be randomly assigned to either the virtual health management community intervention group or a usual care control group. The study will follow participants for approximately 6 months. Participants in the intervention group will receive lifestyle management support through a virtual health management community, including health education, lifestyle guidance, and group-based interaction delivered via a digital platform. Participants will be randomly assigned to either the virtual health management community intervention group or a usual care control group. The study will follow participants for approximately 6 months.
NCT07326891
The goal of this clinical trial is to learn how a Mediterranean-style diet, with and without added exercise, affects blood sugar control in women with prediabetes. Prediabetes means blood sugar levels are higher than normal but not yet type 2 diabetes. Healthy eating and regular physical activity can help prevent diabetes. The investigators aim to answer two main questions: 1. Does adding a supervised program of cycling and rowing exercises to the diet lead to better blood sugar control than the diet alone? 2. Do women who recently returned to normal blood sugar levels respond differently to the exercise program than those who currently have high blood sugar? Participants will be placed into one of three groups based on current blood sugar levels and medical fitness for exercise: * Group 1 (Diet only): Will follow a Mediterranean eating plan for 12 weeks. * Group 2 (Diet + Exercise, Current High Blood Sugar): Will follow the same diet and also do supervised exercise (cycling, then rowing) three times a week for 8 weeks. * Group 3 (Diet + Exercise, Recent Normal Blood Sugar): Will follow the same diet and exercise program as Group 2. These women had prediabetes in the past year but now have normal blood sugar levels. All participants will follow the study protocol for 12 weeks, which includes the following key components: * Dietary Intervention: Adherence to a Mediterranean-style eating plan, which emphasizes high intake of vegetables, fruits, whole grains, legumes, olive oil, and fish. * Continuous Glucose Monitoring: Wearing a continuous glucose monitoring (CGM) device-a small, minimally invasive sensor placed on the upper arm-during multiple 10-day periods. This device tracks interstitial glucose levels throughout the day and night to assess daily glucose patterns. * Blood Sampling and Analysis: Providing fasting blood samples for the measurement of glycemic and metabolic health markers. These include fasting plasma glucose, hemoglobin A1c (HbA1c), fasting insulin, and 2-hour oral glucose tolerance test (OGTT) results. * Anthropometric Assessments: Undergoing standardized measurements of height, body weight, body fat percentage (via bioelectrical impedance), waist circumference, and Body Mass Index (BMI) at scheduled intervals. * Questionnaires: Completing validated surveys to assess habitual dietary intake, sleep quality and duration, and levels of physical activity. Investigators will compare changes in blood sugar control and other health measures from the start to the end of the 12-week study among the three groups.
NCT05681468
The goal of this clinical trial is to compare a healthy KETO diet supplemented with canola oil (KETO-Can) compared to a traditional KETO diet high in saturated fat (KETO-Sat) and low-fat diet (LFD) in adults at high risk of or diagnosed with type 2 diabetes. The main question\[s\] it aims to answer are: * Effects on CVD risk factors (plasma cholesterol, TG, ApoB100, glucose, insulin and HbA1C). * Effects on systemic inflammation and immune function. * Adherence to interventions. Participants will be randomized into 1 of the dietary treatments during which they will follow a Keto or a low-fat diet. Comparisons among groups at 3 and 6 months of intervention will be conducted.
