Active clinical trials for "Obesity, Abdominal"

Over the last 20 years, metabolic health (blood glucose and fats) of Ugandans, particularly residing in urban areas has increasingly become sub optimal. Women are the most affected. Sub optimal metabolic health increases chances of developing diseases known as non-communicable diseases (NCD); for example, type 2 diabetes and heart diseases. NCD are expensive to treat and Uganda lacks the health system to manage them. Therefore, there is need to prevent NCD. Metabolic health is mainly linked to dietary and physical activity behaviour. Studies show an increase in physical inactivity in urban Uganda, especially among women. Likewise, what urban Ugandans eat deviates from healthy recommendations by World Health Organization. For example, 9 in 10 urban Ugandans do not meet the daily fruit and vegetable health recommendations. Research shows that unhealthy eating and physical inactivity behaviours in urban Uganda are due to socio-cultural conceptions (prestige linked to weight gain and consumption of animal protein) and knowledge/skills gaps. Following the intervention mapping protocol, investigators have therefore designed an intervention to help women living in urban Uganda improve eating and physical activity behaviours to align them to healthy recommendations. Investigators target women because they are the most vulnerable health wise; possibility of passing on NCD risk from the mother to the offspring. Women are as well the most strategic for family behavioural change as they oversee dietary decisions in homes. The purpose of this study is to assess the effectiveness of a combined food literacy and physical activity intervention in optimizing metabolic health among women of reproductive age living in Urban Uganda. The study is a cluster randomized control trail divided into two phases: a three months intervention and a three months post-intervention follow-up phase. Primary outcome is waist circumference. The target group are women of reproductive age (18 to 45 years), residing in Kampala. Intervention will be delivered through religious women group structures.

The present study aimed to determine the effect of different interventions on lean body mass maintenance under weight loss conditions in overweight and obese premenopausal women. Three study groups were implemented: (1) Protein supplementation (only) group (2) Protein supplementation and walking intervention (3) Protein supplementation, walking and WB-EMS-application. All protocols were applied for 16 week of intervention. A energy deficit of 500 kcal/d was intended however while group (1) focus consistently on energy restriction (500 kcal/d), in group (2) and (3) a combined physical activity (i.e. walking with a volume representing 250 kcal/d) and energy restriction (250 kcal/d) protocol was applied. Total protein uptake including protein supplementation was calculated to average around 1.2 g/kg body mass per day in groups (1) and 1.5 g/kg body mass/d in group (2) and (3). WB-EMS was applied 1.5x 20 min/week (i.e. each Tuesday and every second Thursday). Primary study endpoint was LBM as determined by Dual Energy x-Ray Absorptiometry.

The main objectives of this study are to collect pilot data to assess feasibility (accrual, retention, compliance), to estimate the variability of outcome measures, and to obtain preliminary estimates of treatment efficacy based on group differences in body composition (decreases in ectopic fat stores while maintaining lean mass), cardio-metabolic risk factors including glucoregulatory function (glucose, insulin), inflammation (C-reactive protein, IL-6), blood pressure and lipids (HDL, LDL, TC, TG), and measures of physical function and muscle strength. While this is just a pilot study, randomization will be used so that the investigators can obtain a realistic estimate of accrual (which is often less in a randomized trial) and an unbiased estimate of treatment efficacy. The investigators will accomplish these objectives by conducting a 2-arm, 3-month randomized, clinical trial in 24 older (60-79), abdominally obese (BMI ≥30 kg/m2 and waist circumference ≥ 102 cm and ≥ 88 cm in men and women, respectively) men and women. Participants will be randomized to a soy-based or animal-based, 3-month, hypocaloric dietary intervention to achieve our specific aims: Primary Aim: To determine our ability to recruit and retain older, obese adults to a 3 month soy-based meal replacement weight loss intervention and assess the study participant's ability to adhere to the intervention protocol (weight, compliance logs, serum isoflavones). Secondary Aims: To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on measures of body composition, including abdominal (total, subcutaneous and visceral fat), liver, and pericardial fat; anthropometrics (body weight, waist/hip circumference); and whole body fat and lean mass. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on biomarkers of cardiometabolic risk including glucoregulatory function (glucose, insulin), inflammation (C-reactive protein, IL-6), blood pressure and lipids (HDL, LDL, TC, TG). To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on physical function (short physical performance battery, 400-m walk) and muscle strength (grip and knee extensor strength) and size (CT thigh muscle). To document any adverse events associated with the soy-based meal replacement.

Rationale: It is well established that increased intake of saturated fatty acids (SFA) is associated with incidence of cardiovascular heart disease (CHD). This effect is mediated by dietary saturated fat's impact on fasting plasma cholesterol levels. Research is needed to clarify the association between dietary fatty acids and metabolic risk markers beyond lipid profile. World Health Organisation (WHO) has recommended reduced intake of SFA with energy replacement from monounsaturated fatty acids (MUFA) or carbohydrates (CARB). However, limited evidence is available on the effects of dietary fatty acids on insulin sensitivity and secretion. The current study is designed to investigate the effects of SFA versus MUFA versus CARB on insulinemic response and lipid metabolism in healthy individuals with central obesity. Study design: A randomized, crossover, single blind design study was carried out. The subjects consumed controlled diets for 6 weeks each. They were provided 3 meals per day during weekdays in which SFA, MUFA and CARB diet was assigned to them randomly. Protein content was standardised at 14% energy. The SFA and MUFA diets each provided 31.5% energy intake from fat, with 69% of the total fats replaced by test fats (approximately 49 g/d based on a 2000 kcal basic diet). Each individual fatty acid provided approximately 7% of the total energy intake. The CARB diet provided approximately 34 g/day experimental fat based on a 2000 kcal basic diet. The CARB diet replaced 7 % energy of carbohydrate from total fat with the exchange from oleic acid (C18:1). Hypothesis: Changing energy from dietary fat (SFA and MUFA) to carbohydrate will influence insulin sensitivity, endothelial and vascular function, pro-inflammatory markers and lipid metabolism differently in individuals with metabolic syndrome. SFA (palm olein) may be comparable with MUFA (high oleic sunflower oil) with regards to its effects on insulin sensitivity, endothelial and vascular function and inflammation

The study investigates whether a caloric restricted dietary regime can prevent onset and/or progression of chronic kidney disease in type 2 diabetic patients with abdominal obesity, through the amelioration of concomitant metabolic abnormalities such as insulin resistance, dyslipidemia, hypertension and inflammation, possible risk factors for the onset of kidney disease. The main aim of the study is therefore to evaluate the renoprotective effect of caloric restriction (CR) on subjects at risk of nephropathy. Secondary aim is to better understand how dietary implementation can modulate renal disease and its associated metabolic abnormalities.

The aim of this study is to develop an intervention that will produce a sustained improvement in physical activity and chronic stress as a means to slow the menopause-related accumulation of visceral adipose tissue in mid-life women.

This study evaluates the effect of intermittent calorie restriction versus continued calorie restriction on weight loss, gene expression profile of subcutaneous adipose tissue and abdominal fat distribution.

This pilot project will determine whether a diet culturally-adapted to Puerto Ricans can effectively decrease cardiometabolic risk for diabetes. This will help define a culturally-appropriate, feasible, and sustainable diet intervention aimed at reducing type 2 diabetes and obesity outcomes.

Background:Knee osteoarthritis is more common in patients with type-2 diabetes mellitus, however it is not known whether this effect is caused by diabetes itself or concominant abdominal obesity. Objectives:The aim of this study is to determine whether type-2 diabetes itself, independent of abdominal obesity, is a risk factor for femoral cartilage, knee osteoarthritis and poor quality of life. Design:A cross-sectional design. Settings:Training and research hospital in Turkey. Patients and Methods:Female patients was enrolled in this study and divided into two groups: according to presence or absence of diabetes. Later, both the patients with and without abdominal obesity was divided into two groups according the presence of diabetes. Main Outcome measures:Clinical parameters were visual analog-scale, gait speed and short form-36. Knee radiographs were evaluated according to Kellgren Lawrance-Scale. And ultrasonography parameters were the measurements of distal femoral cartilage thickness. Sample size:126

This study has two objectives: 1) to check that the daily consumption of two eggs with a particular fatty acid pattern rich in n-3 polyunsaturated fatty acids (α-linolenic acid, docosahexaenoic acid), conjugated-linoleic acid and conjugated-linolenic acid is well tolerated by the consumer ; 2) to evaluate the effects of the consumption of these eggs on health parameters in subjects presenting a risk of developing a metabolic disorder. This monocentric study is an interventional, randomized, double-blind, control study.
