Filter by:The goal of this study is to explore the effects of FeatForward on physical activity and cardio-metabolic risk factors. The study will be implemented as a 2-arm randomized controlled trial (RCT) comparing the effects of FeatForward in patients assigned to use the application versus a control group who will not use the app over a 6-month follow-up period. The investigators hypothesize that subjects using FeatForward will be more physically active and will achieve greater improvements in their cardio-metabolic risk (CMR) factors than a usual care control group that will not use the app over a 6-month period.
This study is intended for inactive, middle-aged adults with untreated pre-hypertension who live in the Urbana-Champaign area, who are interested in a comprehensive program designed to enhance physical activity & reduce blood pressure. All participants will be asked to engage in a program developed in accordance with American Heart Association's recommendations. Specifically, the program will encourage and support lifestyle behavior changes such as quitting smoking, eating heart-healthy food, and reducing excessive alcohol, in addition to weekly exercise. The exercise program will involve a 14-week aerobic training program (3 weekly sessions, scheduled at study participants' convenience), and 2 pre- and 2-post-testing sessions.
This study compares the effects of a one-month diet high in saturated fat (SF), glycemic index (GI), and salt (Na+) to a diet low in these nutritional parameters on memory and other cognitive functions, on MRI measures of brain structure, function, and perfusion, as well as on blood and cerebrospinal fluid levels of amyloid-beta (Aβ), insulin, lipids (total cholesterol, HDL, LDL, oxidized LDL, and triglycerides), cytokines, apolipoprotein E (ApoE), apolipoprotein J, cortisol, soluble low density lipoprotein receptor-related protein (sLRP), and glucose in middle-aged adults (45-65 years of age) with normal cognition or mild cognitive impairment.
The purpose of this study is to evaluate the effectiveness of a technology-based behavioral Healthy Lifestyle intervention on adiposity (body mass index z-score), blood pressure (mean clinic systolic BP), and heart size (LVM) in comparison to standard care.
Hypertension affects about 30% of the United Kingdom population and is causally implicated in the aetiology of renal disease, cardiovascular disease and stroke. Ageing, obesity, a poor diet and low levels of physical activity are all risk factors. Studies have shown that adherence to a Mediterranean diet is protective against hypertension and its associated morbidities; olive oil is believed to be a key beneficially bioactive component of that diet. As a source of lipids olive oil is an unremarkable blend of monounsaturated, polyunsaturated and saturated fatty acids; it is however rich in phenolic compounds, principally oleuropein and hydroxytyrosol, which may be of benefit to health. A recent randomised intervention trial in predominantly hypertensive volunteers showed that adherence to a Mediterranean diet supplemented with extra virgin olive oil, reduced blood pressure and other measures of cardiovascular disease risk. Olive phenolics can be extracted cheaply from the waste products of olive oil manufacture, such as the plant leaf and these are used as dietary supplements. In intervention studies in hypertensive or borderline hypertensive patients, olive leaf extract consumption has been shown to reduce blood pressure. Another intervention with established efficacy for improving blood pressure is to increase physical activity. The 'Start Active, Stay Active', Chief Medical Officers report on physical activity recommends that adults achieve 150 minutes of moderate intensity physical activity per week, while data in that report suggest that fewer than 40% of adult men and 30% of adult women achieve these targets. Adherence to the physical activity guidelines may in fact be much worse in sub-sections of the population at higher risk of hypertension. From a public health perspective, holistic guidelines for the prevention of hypertension, or its early diagnosis and management, based around a healthy diet and lifestyle are preferable to pharmaceutical intervention. Lifestyle interventions are economically favourable and they come with fewer side effects and perhaps wider health benefits than antihypertensive drugs. The aim of the study is to evidence the synergistic benefits of consuming plant (and specifically olive) phenolics alongside achieving the recommended guidelines for physical activity in individuals with elevated blood pressure.
The specific aim of the proposed study is to address the efficacy of conventional full-fat dairy products as part of the normal routine diet for improving vascular function and reducing blood pressure in middle-aged and older adults with elevated blood pressure. The investigators hypothesize that dietary intervention including whole milk and full-fat milk products will induce significant decreases in systolic blood pressure and arterial stiffness. The investigators also test the hypothesis that the reductions in blood pressure will be associated with the corresponding decreases in arterial stiffness and/or increases in endothelial vasodilatory function as well as improvements in arterial baroreflex sensitivity. If our hypotheses are supported by the results, the information could be used as a basis for recommendations for the use of whole milk and full-fat milk products in the secondary prevention of elevated blood pressure and vascular dysfunction.
The purpose of this research study is to examine the efficacy of two stress management interventions in reducing blood pressure (BP) in patients who have prehypertension (BP between 120/80 and 139/89). It is expected that participants will be better able to control their BP through reducing stress and increasing healthy lifestyle behaviors.
This study evaluated effects of red ginseng consumption on blood pressure (BP) and fasting plasma metabolomes.
The purpose of this study is to compare the effect of 6-weekly, 20 minute sessions of 2 online behavioral sleep interventions (cognitive behavioral therapy or healthy sleep habits) on blood pressure, sleep, depressive symptoms and anxiety in people with insomnia and prehypertension or hypertension.
In this study we will assess the effects of bioactive peptide rich wheat products on blood pressure and estimated cardiovascular disease risk. This will be a pilot, explorative, cross-over, randomized double-blind 2 groups x 2-arms controlled, clinical trial. The intervention will be based on commercially-packaged pasta, which will appear and taste the same; (i) low dose bioactive peptides vs. (ii) high dose bioactive peptides. Inclusion Criteria will be: Male and female non-diabetic adult volunteers at increased estimated CV risk (ESC/EAS SCORE) with SBP 130-139 mmHg and/or DBP 85-90 mmHg); Age included between 40 and 70 years old; Primary prevention for CVD but otherwise in good general health and have had no major illness in the previous 6-months; Volunteer providing their signed and dated informed consent form. Exclusion Criteria will be: Severe medical illness/chronic disease/gastrointestinal pathology (e.g. coeliac disease); Secondary prevention for CVD; Treatment with drugs potentially affecting BP (including antihypertensive drugs) or other related CV risk factors; Consumption of nutraceuticals, botanical extracts or other vitamin supplements; Volunteer diagnosed as being hypertensive A total of 60 participants will be recruited and following adherence to a standardized diet for a 4-week period, will be randomly assigned to complete one of 2 treatment sequences by consuming a prescribed quantity of pasta products for a 4-week period followed by a 4-week washout before random assignment to the 2nd treatment. The Primary Outcome will be the modification of office blood pressure (assessed by systolic and diastolic BP, pulse and mean pressure (mean of 3 standing & sitting measures) and 24-hour blood pressure. Additional outcomes include: Anthropometric parameters (Weight, WC, HC, WC/HC, ICO, BMI), Glucose and Lipid profile (TC, LDL-C, HDL-C, TG, non-HDL cholesterol, risk ratios), Estimated CVD risk changes (EAS/ESC SCORE Charts), Measures of vascular health (FMD, PWA, PWV, Aix), Liver and renal functionality biomarkers, 24-h urine collection at baseline of treatment phase 1 and endpoint of the final phase will be analysed to account for potential confounding of urinary sodium excretion (intake) As required by the GCPs and GLPs, all the SOPs have already been established and all the personnel to be involved in the study is continuously trained in trials with similar outcomes
