Active clinical trials for "Obesity"

Obesity is recognized as a major public health problem. Recent research suggests the involvement of the gut microbiota in the development of obesity. Indeed, obese people are characterized by a dysbiotic intestinal microbiota. Periodontitis are chronic inflammatory oral pathologies linked to an imbalance between the bacterial etiological factor, oral dysbiosis, and the host's immune defenses.They lead to the destruction of the supporting tissues of the tooth and an apical migration of the periodontal attachment system, thus leading to the formation of the pathognomonic entity of the disease, the periodontal pocket.the presence of bacteria of oral origin such as Porphyromonas gingivalis (Pg) has been demonstrated in the adipose tissue of obese patients inducing a chronic low-grade inflammatory response by macrophages which leads to the proliferation of adipocyte precursors predisposing to obesity. The main objective is to assess the average amount of Porphyromonas gingivalis (Pg) in the saliva of obese people (BMI ≥ 30) with periodontitis.

The goal of this research study is to compare two enhancements to well-child visits at Geisinger designed to promote family-centered counseling for the prevention of obesity in a high-risk population of rural, lower income, preschool-aged children. Compared to the standard well-child visit, enhancements will offer advantages to obesity prevention, parent involvement in counseling, lifestyle behaviors, and food resource management.

In this is an observational study, obese patients that administed and followed in endocrinology clinic of Marmara University Medical school hospital will follow for clinical and laboratory parameters prospectively for 5 years

The obesity epidemic is growing worldwide and in the UK this is perpetuated with a third of women classified as overweight/obese in 2020. Many of these woman are of childbearing age and go on to have high risk pregnancies which are often complicated by gestational or pre-existing (type 2 diabetes mellitus (GDM, T2DM). Bariatric surgery is the most successful treatment of sustainable weight loss and is associated with a reduction in rates of GDM, pre-eclampsia, delivery of large babies but increased risk of delivery of small babies and preterm delivery. The aims of the study are to investigate the maternal and fetal/neonatal, biophysical and biochemical, intra-uterine environment and postnatal profile of pregnancies: affected by maternal obesity and/or GDM/T2DM compared to pregnancies with normal maternal body mass index (BMI). with previous maternal bariatric surgery compared to pregnancies without previous bariatric surgery but matched for maternal pre-surgery and early pregnancy BMI.

In this study it is researched how preventive and curative healthcare for children with overweight and obesity was conducted during the Covid-19 pandemic, which barriers were noticed by professionals, and how new methods (such as e-health and telemonitorning) for coaching, communication and healthcare were used and experienced.

Background: Studies suggest that overweight girls may be developing breast tissue, and therefore starting puberty, earlier than normal weight girls. However, it is hard to distinguish breast tissue from fatty tissue. Researchers think that by using breast ultrasound, among other tests, they can do a better job of telling whether an overweight girl has breast tissue. This will help them understand if overweight girls are truly entering puberty before normal weight girls. Objective: To find out if overweight girls go through puberty earlier than normal weight girls. Eligibility: Healthy girls 8-14 years old who: Are normal weight or overweight Have some breast development Have not started their first period Design: Parents of participants will be screened over the phone. Most participants will have 1 visit. However, they can choose to have multiple visits within 4 weeks. The visit will include: Physical exam that includes examination of the breasts and genital area Breast ultrasound: A small hand-held device will be passed back and forth over the chest. It uses sound waves to create a picture of the breast tissue. Pelvic ultrasound: A small, handheld device will be passed back and forth over the lower belly. It uses sound waves to create a picture of the ovaries. Urine and blood test A special x-ray called a DXA to measure the amount of fat in the body: The participant will lie still on a table while the x-ray takes pictures of the body. X-ray of the hand: The picture will tell researchers how mature the participant s bones are. Participants may be asked to come back 6 months later to repeat these tests.

This study aims to investigate genetic causes of early childhood obesity. The investigators will enroll children and young adults with severe early onset obesity (BMI > 99th percentile) diagnosed prior to 6 years of age. The investigators will ask questions about the health and eating behavior of the participants, and perform a brief physical examination. The investigators will collect saliva or blood to perform genetic testing from the participants and invite family members to enroll in the study.

The goal of this clinical trial is to test whether the Food FARMacia intervention to reduce food insecurity is feasible and accepted among families with an infant age 6 to less than 18 months receiving pediatric primary care at Columbia / New York-Presbyterian Ambulatory Care Network. All participants will receive nutrition education and anticipatory guidance to support healthy meal preparation in addition to usual care.

The overall objective of this study is to better understand the respiratory mechanisms provoking dyspnea on exertion in obese asthmatic children.

This study will evaluate the feasibility and obtain a preliminary estimate of efficacy of feeding 15 g/day of a new novel prebiotic dietary fiber, termed polylactose, in 40 children (8-12 years old) with obesity (body mass index [BMI]-percentile >/= 95th) who have magnetic resonance imaging (MRI)-confirmed non-alcoholic fatty liver disease [NAFLD] (hepatic fat fraction >/= 5.5%), compared to a placebo of 15 g/d of cellulose, an inert dietary fiber.
