Effect of Changes to the Neighborhood Built Environment on Physical Activity in a Low-Income African American Neighborhood

Neighborhood Baseline, % Follow-Up, %
INA 36.7 41.0
INB 40.5 40.6
CN1 37.0 23.9
CN2 39.3 37.5

Figure 2. Percentage of people observed in intervention and comparison neighborhoods engaged in moderate and vigorous physical activity, at baseline (2006) and follow-up (2008), Partnership for an Active Community Environment Project, New Orleans, Louisiana. Neighborhood-by-time interaction was significant (χ2 test, P = .001), and differences between baseline and follow-up for INA and CN1 were significant (Pearson χ2 test, P < .001). Abbreviations: INA, Area A of intervention neighborhood (path); INB, Area B of intervention neighborhood (playground); CN1, comparison neighborhood 1; CN2, comparison neighborhood 2.
