This study evaluates the associations between exposure to air pollutants, green space, and the gut microbiome and metabolome.
A rapidly evolving field of study suggests a link between the gut microbiome and fecal metabolome with obesity. Recent studies show that environmental exposures, such as ambient air pollution (AAP) exposure can affect gut bacteria and modify risk for obesity. Additionally, proximity to green space has been shown to reduce exposure to air pollutants and increase gut microbial diversity. The investigator's preliminary work has shown that near-roadway air pollution exposure was positively correlated with gut microbial taxa that have been linked with obesity. These findings suggest that air pollution exposure may increase susceptibility to obesity through alterations in the composition and function of the gut microbiome. Despite this, no studies have systematically examined the impact of air pollutants and green space on the gut microbiome and metabolome among adolescents. The overall goal of this research is to determine whether exposure to air pollutants and/or green space affect the gut microbiome and metabolome in Hispanic young adults residing in Denver, Colorado. This study will examine residential-based estimates of air pollution exposure and green space and also perform detailed gut microbial and metabolite profiling in 100 adolescent and young adults.

Obesity affects over one third of US adults (>72 million, with BMI ≥30 kg/m2), and the proportion of US adults with BMI ≥40 kg/m2 has doubled in the last 20 years. Obesity is associate...
The purpose of this study is to design and demonstrate the feasibility of implementing moderate and intensive environmental obesity prevention programs at major worksites.
Despite extensive study of the obesity epidemic, research on whether obesity has risen faster in lower or in higher socioeconomic groups is inconsistent. This study examined secular trends in obesity ...
The prevalence of obesity in childhood is of high concern, especially in deprived populations. We explored trends in obesity following the introduction of a citywide strategy focused on preschool chil...

In Europe, although the prevalence of childhood obesity seems to be plateauing in some countries, progress on tackling this important public health issue remains slow and inconsistent. Breastfeeding h...
Treating pediatric severe obesity is challenging because of the complex biological, behavioral, and environmental factors that underpin the disease. The multifactorial etiology of obesity combined wit...
A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.
The condition of weighing two, three, or more times the ideal weight, so called because it is associated with many serious and life-threatening disorders. In the BODY MASS INDEX, morbid obesity is defined as having a BMI greater than 40.0 kg/m2.
A sub-PHENOTYPE of obese individuals who have a risk for CARDIOVASCULAR DISEASES between that of healthy individuals with normal weight and unhealthy individuals with obesity.
BODY MASS INDEX in children (ages 2-12) and in adolescents (ages 13-18) that is grossly above the recommended cut-off for a specific age and sex. For infants less than 2 years of age, obesity is determined based on standard weight-for-length percentile measures.
Agents that increase energy expenditure and weight loss by neural and chemical regulation. Beta-adrenergic agents and serotoninergic drugs have been experimentally used in patients with non-insulin dependent diabetes mellitus (NIDDM) to treat obesity.
Obesity is the condition in which excess fat has accumulated in the body (mostly in subcutaneous tissues). clinical obesity is considered to be present when a person has a BMI of over 30 (Oxford Dictionary of Medicine). It is becoming increasing common i...
