Satellite-Based and Street-View Green Space and Adiposity in US Children
Authors' conclusion
This cohort study of US children suggests that higher levels of satellite-based NDVI greenness and percentages of street-level green space components (flowers, plants, and fields) were associated with lower adiposity. The findings support the exploration of increasing residential green space levels and adding specific green space components as an urban planning and public health intervention strategy to combat the prevalence of childhood obesity in the US.
Study context
- Population
- US children in the Project Viva cohort followed from mid-childhood (mean 8.0 years) and early adolescence (mean 13.3 years) through late adolescence (mean 17.8 years), 2007–2021children at baseline
- Participants
- 843 children
- Exposure
- Higher vs lower satellite-based normalized difference vegetation index (NDVI) and street-view green space
- Outcome
- BMI and waist circumference z scores; total FMI and trunk FMI by DXA
- Follow-up
- Early or late adolescence
