Six out of ten low-income, uninsured children in Los Angeles County had difficulty accessing needed medical care in 2002/2003. Based on the Los Angeles County Health Survey, it appears that L.A.s Childrens Health Initiative has the potential to improve access to health care services for these children if they enroll in public health programs. This analysis suggests that children enrolled in the Healthy Kids program would have fewer unmet health and dental needs and would be more likely to receive well-child and regular care.
