Public Housing Redevelopment and Childhood Obesity.

Area of Science:

• Public Health
• Urban Planning
• Environmental Health

Background:

• Childhood obesity disproportionately affects low-income and minority communities with poor housing and neighborhood environments.
• Evidence on comprehensive interventions addressing housing, built, and social environments is limited.
• This study evaluates early impacts of the Jordan Downs redevelopment on children's obesity.

Purpose of the Study:

• To assess the effects of a decade-long redevelopment of Jordan Downs public housing on childhood obesity.
• To examine changes in children's weight status and related behaviors two years into the redevelopment.
• To understand the impact of integrated housing and environmental improvements on health outcomes.

Main Methods:

• Longitudinal study of 399 children in Jordan Downs and a comparison group.
• Difference-in-differences analysis to compare changes in outcomes.
• Primary outcomes included overweight/obesity, BMI z score, waist circumference, and waist-to-height ratio.

Main Results:

• Jordan Downs children showed a lesser increase in overweight/obesity prevalence (14.7 pp) and BMI z score (0.15).
• Redevelopment was associated with reduced waist circumference (5% less) and waist-to-height ratio (3.9% less).
• Children in Jordan Downs consumed fewer sugar-sweetened beverages and engaged more in physical activity.

Conclusions:

• The Jordan Downs redevelopment was associated with a significant reduction in the increase of childhood obesity prevalence.
• Improvements in housing and neighborhood environments may contribute to better child health outcomes.
• This study highlights the potential of whole-of-community interventions in addressing health disparities.
