Racial Residential Segregation and Disparities in Obesity among Women.

The high rate of obesity among black women in the USA is a significant public health problem. However, there is limited research on the relationship between racial residential segregation and disparities in obesity, and the existing evidence is limited and results are mixed. This study examines the relationship between racial residential segregation and obesity among black and white women. We conducted this cross-sectional study by joining data from the 1999-2004 National Health and Nutrition Examination Survey with data from the 2000 US Census. Multilevel logistic regression models found that for every one-point increase in the black isolation index, there was a 1.06 (95 % confidence interval (CI) = 1.01, 1.11) times higher odds of obesity for black women. In order to address the disparately high rates of obesity among black women, health policies need to address the economic, political, and social forces that produce racially segregated neighborhoods.
