Morbidity and mortality: Relevant data were/will be also retrieved via local multiple health information systems.

NCT ID: NCT03169257 Active, not recruiting - Clinical trials for Cardiovascular Diseases

Paediatric Obesity and Cardiovascular Dysfunction

Start date: January 15, 2015
Phase: N/A
Study type: Interventional

Background Childhood obesity has been related to an impaired cardiovascular structure and function. Aims of this study will be to evaluate early cardiovascular abnormalities in a large population of obese children and adolescents compared with a normal weight counterpart, to investigate the potential association with insulin resistance (IR), serum uric acid (sUA), metabolic syndrome (MetS), plasmatic markers of inflammation and oxidative stress and adipokines, to evaluate changes in cardiovascular dysfunction after 6 and 12 months of a behavioral treatment (isocaloric Mediterranean balanced diet plus daily aerobic physical activity). Subjects and methods This was a single-center case-control study. Eighty obese (OB) subjects (6-16 years) and 20 normal weight (NW) matched controls were consecutively recruited. In the whole population we will perform an anthropometric and a cardiovascular assessment. OB patients will also undergo an OGTT and biochemical evaluations. In the OB group, all these evaluations will be performed at baseline and after 6 (T6) and 12 months (T12) of diet plus aerobic training.

NCT ID: NCT03151694 Active, not recruiting - Obesity Clinical Trials

Brain-to-Society Diagnostic for Prevention of Childhood Obesity and Chronic Disease

Start date: February 1, 2011
Phase: N/A
Study type: Observational

This multi-national program applies a breakthrough approach to childhood obesity called, Brain-to-Society (BtS) Diagnostic Approach. In Montreal, Canada and Palwal, India, the investigators will recruit two cohorts of 612 children (6 to 12 years; 306 boy/306 girls) where Whole-of-Society (WoS) transformations are taking place (industrialized societal context with peaking childhood obesity and where a broad governmental plan to promote healthy lifestyle has been adopted -Canada; developing societal context with increasing childhood obesity if replication of past pathways that have lead to double burden; India) are taking place along with World Health Assembly (WHA) resolution A63-12 for marketing of food to children. Individual-level BtS Diagnostic will examine the degree to which individual differences in genetics and biology and differences in the environmental exposures modulate the behavioral, body weight/fatness and nutritional risk over time in the context of WoS transformations. Societal-level BtS Diagnostic shall examine the influence of decisions in policy, investment, business and innovation made by different stakeholders (government, private sector, civil society in health and non-health society systems including agriculture, business and media practices) on the community.

NCT ID: NCT03147079 Active, not recruiting - Clinical trials for Obesity Complicating Childbirth

Study of Antenatal Care Intervention Directed to Pregnant Women With Obesity

Mighty Mums
Start date: January 1, 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to determine whether a behavioural intervention focusing on diet and physical activity is cost-effective in decreasing weight gain during pregnancy among pregnant women with body mass index above 30, and has effect on the weight of offspring at birth and at 2.5 years of age

NCT ID: NCT03144609 Active, not recruiting - Obesity Clinical Trials

Mechanical Ventilation of Obese Patients During Oral Surgical Procedures

Start date: November 2015
Phase: N/A
Study type: Interventional

The prevalence of obese patients in a great number of patients scheduled for elective surgery under general anesthesia has been on the increase. Recent studies suggest an intraoperative protective mechanical ventilation for the obese. Surgical procedures in the oral cavity increase the risk of perioperative complications of obese patients. By making this randomized clinical study, investigators want to determine whether the protective intraoperative ventilation with the use of higher positive end-expiratory pressure and recruitment maneuvers compared to ventilation with low positive end-expiratory pressure and without recruitments cause better postoperative respiratory function parameters of obese patients during oral surgical procedures. Investigators also aim to establish the fact which value of a positive end-expiratory pressure has a favorable impact on the respiratory function without negative hemodynamic effect.

NCT ID: NCT03134040 Active, not recruiting - Obesity Clinical Trials

Small Monetary Incentives to Promote Exercise (Exercise4Good; EX4G)

Start date: May 2016
Phase: N/A
Study type: Interventional

This study is for physically inactive adults with an active membership at a Greater Providence Young Men's Christian Association (YMCA). Participants will receive weekly feedback on their attendance at the YMCA, and will be enrolled in the study for 1 year. Participants will be assigned to one of three conditions, to either receive weekly: (i) monetary incentives, (ii) donations to a charity of their choice, or (iii) feedback only. In order to continue to receive incentives, participants must maintain an active membership at the YMCA.

NCT ID: NCT03131284 Active, not recruiting - Obesity, Childhood Clinical Trials

Prevention of Obesity in Toddlers (PROBIT) Trial.

Start date: July 1, 2014
Phase: N/A
Study type: Interventional

AIM: to reduce the prevalence of overweight and obesity at two years of age in the intervention group compared to the control group. METHODS: Eleven primary paediatricians were randomized to the intervention group and intensively trained about the trial intervention. Each of them was asked to consecutively recruit the parents of at least 30 newborns taken in charge within the first year of the study, and to provide them with standardized oral and written information on protective practices during all the well visits scheduled in the first two years of the child's life. Another eleven primary paediatricians were randomized to the control group, and were asked to consecutively recruit the parents of at least 30 newborns taken in charge within the first year of the study and to provide them with usual care and follow-up. When all recruited children have completed the second year of life, the two groups of toddlers will be compared as regards the prevalence of overweight/obesity, defined by WHO cut-offs of the weight/lenght ratio.

NCT ID: NCT03129932 Active, not recruiting - Obesity Clinical Trials

Effects Gluten Intake on Body Composition, Energy Expenditure and Adipokine Profile in Non-celiac Women With Obesity

Start date: January 10, 2015
Phase: N/A
Study type: Interventional

This is a double-masked, crossover, randomized, controlled study that aims to evaluate, in women with obesity, a possible influence of wheat gluten on food choices, body weight, resting metabolism and circulating inflammation markers and adipokines. The volunteers will be randomized into two groups, half of them will initiate the experiment by taking 2 placebo muffins daily for 4 weeks (Placebo phase) and the remnant volunteers will take 2 corn muffins containing 12g of gluten/each for 4 weeks (Gluten phase). At the 1st, 4th and 8th experimental weeks will be evaluated body weight, body composition, lipid profile, glucose, insulin, leptin, adiponectin, and inflammatory markers.
