  1. Parents: 80% of cases
  2. Caretakers at daycare, or nursery school: 2%
  3. Abuse is rarely a single event, but rather one of repeated and increasing Violence
  4. Perpetrators cross all socioeconomic , ethnic, racial, gender and setting boundaries
2. Types of abuse
  1. Neglect: 52%
  2. Physical abuse: 25%
3. Ages of abused children
  1. Most abused children are under age 6 months
  2. Age 7 years old or younger: 50%

V. Precautions

Child Abuse is a commonly missed diagnosis with potentially devestating consequences
1. Initially missed abusive Head Injury: 30% of cases
2. Initially missed abusive Fractures: 20% of cases
3. Identify Child Abuse early, when it is still associated with minor injury
Consider every injury and illness in a child in the context of the reported history, mechanism and developmental stage
1. Persistent Vomiting without Diarrhea despite >1-3 days of illness (consider Head Injury)
2. Falls in under age 3 years old (and especially under age 6 months) should be considered carefully
3. Consider Consultation with a Child Abuse expert if a presentation raises a red flag
4. Cardiac Arrest in young children (or BRUE)
