[영문]Extreme racial/ethnic disparities exist in children’s access to qqqquot;opportunity neighborhoods.qqqquot; These disparities arise from high levels of residential segregation and have implications for health and well-being in childhood and throughout the life course. The fact that health disparities are rooted in social factors, such as residential segregation and an unequal geography of opportunity, should not have a paralyzing effect on the public health community. However, we need to move beyond conventional public health and health care approaches to consider policies to improve access to opportunity-rich neighborhoods through enhanced housing mobility, and to increase the opportunities for healthy living in disadvantaged neighborhoods.
