Understanding how outdoor time and stress affect childhood obesity through gut health

Childhood Obesity: the role of the gut Microbiome, outdoor Time, and Stress(COMETS)

NIH-funded research Washington State University · NIH-11031986

This study is looking at how things like the gut bacteria in kids, time spent playing outside, and stress can affect childhood obesity, especially in families with fewer resources, and it’s exploring whether outdoor preschools can help kids stay healthier and happier.

What this research studies

This research investigates the relationship between childhood obesity and factors such as the gut microbiome, outdoor time, and stress levels in children. It focuses on how social determinants of health, particularly in low socioeconomic status households, contribute to obesity risk. By exploring outdoor preschools as a potential intervention, the study aims to enhance resilience against these risk factors and improve children's health outcomes. The methodology includes assessing gut microbiome diversity and its connection to obesity while considering environmental influences.

Who could benefit from this research

Good fit: Ideal candidates for participation are children aged 0-11 years, especially those from low socioeconomic backgrounds.

Not a fit: Children who are not affected by obesity or those from high socioeconomic status households may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to effective strategies for preventing and managing childhood obesity, particularly in at-risk populations.

How similar studies have performed: While research on outdoor time and its effects on health is emerging, rigorous studies specifically linking outdoor preschools to childhood obesity prevention are limited, making this approach relatively novel.
