Among children whose regular source of care is a community health center, continuity of care with one specific clinician is associated with better preventive care than not having a specific clinician, with having another source of sick care, or having no regular sick care source. When continuity of care is considered, there is no effect of insurance. That is, having a good source of primary care is more important to preventive care than is insurance.
