are all forms of abuse, because they injure the integrity and dignity of a child, even if their consequences are not visible right away.Physical abuse as a child can lead to physical and mental difficulties in the future, including re-victimization, personality disorders, post-traumatic stress disorder (PTSD), dissociative disorders, depression, anxiety, suicidal ideation, eating disorders, substance use disorders, and aggression. Physical abuse in childhood has also been linked to homelessness in adulthood. Sexual abuse
Child sexual abuse (CSA) is a form of child abuse in which an adult or older adolescent abuses a child for sexual stimulation. Sexual abuse refers to the participation of a child in a sexual act aimed toward the physical gratification or the financial profit of the person committing the act. Forms of CSA include asking or pressuring a child to engage in sexual activities (regardless of the outcome), indecent exposure of the genitals to a child, displaying pornography to a child, actual sexual contact with a child, physical contact with the childs genitals, viewing of the childs genitalia without physical contact, or using a child to produce child pornography. Selling the sexual services of children may be viewed and treated as child abuse rather than simple incarceration.Effects of child sexual abuse on the victim(s) include guilt and self-blame, flashbacks, nightmares, insomnia, fear of things associated with the abuse (including objects, smells, places, doctors visits, etc.

As of 2006, for instance, Paulo Sergio Pinheiro wrote in the UN Secretary-Generals Study on Violence Against Children:

Corporal punishment involves hitting (smacking, slapping, spanking) children, with the hand or with an implement – whip, stick, belt, shoe, wooden spoon, etc. But it can also involve, for example, kicking, shaking or throwing children, scratching, pinching, biting, pulling hair or boxing ears, forcing children to stay in uncomfortable positions, burning, scalding, or forced ingestion (for example, washing childrens mouths out with soap or forcing them to swallow hot spices). Most nations with child abuse laws deem the deliberate infliction of serious injuries, or actions that place the child at obvious risk of serious injury or death, to be illegal. Bruises, scratches, burns, broken bones, lacerations — as well as repeated "mishaps," and rough treatment that could cause physical injuries — can be physical abuse. Multiple injuries or fractures at different stages of healing can raise suspicion of abuse. The psychologist Alice Miller, noted for her books on child abuse, took the view that humiliations, spankings, and beatings, slaps in the face, etc.
