A study of factors associated with teenage pregnancy in , , found that forced sexual initiation was the third most strongly related factor, after frequency of intercourse and use of modern contraceptives. Forced sex can also result in unintended pregnancy among adult women. In India, a study of married men revealed that men who admitted forcing sex on their wives were 2.6 times more likely to have caused an unintended pregnancy than those who did not admit to such behavior. Should pregnancy result from a first-time encounter it would carry a higher risk of , the condition in which the mother's body reacts adversely to the proteins of the fetus.
Violent or forced sex can increase the risk of transmitting . In forced vaginal penetration, abrasions and cuts commonly occur, thus facilitating the entry of the virus through the . Adolescent girls are particularly susceptible to HIV infection through forced sex, and even through unforced sex, because their vaginal mucous membranes have not yet acquired cellular density sufficient to provide an effective barrier that develops in the later teenage years. Those who suffer are also considerably more susceptible to HIV than would be the case if the sex were not forced, since anal tissues can be easily damaged, again allowing the virus an easier entry into the body.
Being a victim of sexual violence and being susceptible to HIV share a number of risk behaviors. Forced sex in childhood or adolescence, for instance, increases the likelihood of engaging in unprotected sex, having multiple partners, participating in sex work, and substance abuse. People who experience forced sex in intimate relationships often find it difficult to negotiate condom use either because using a condom could be interpreted as mistrust of their partners or as an admission of promiscuity, or else because they fear experiencing violence from their partners. Sexual coercion among adolescents and adults is also associated with low self-esteem and depression factors that are associated with many of the risk behaviors for HIV infection.
Research on women in shelters has shown that women who experience both sexual and physical abuse from intimate partners are significantly more likely to have had sexually transmitted diseases.
Childhood and adulthood victims of rape are more likely to attempt or commit suicide. The association remains, even after controlling for sex, age, education, symptoms of post-traumatic stress disorder and the presence of psychiatric disorders. The experience of being raped can lead to suicidal behavior as early as adolescence. In Ethiopia, 6% of raped schoolgirls reported having attempted suicide. A study of adolescents in Brazil found prior sexual abuse to be a leading factor predicting several health risk behaviours, including suicidal thoughts and attempts.
Rape and other forms of sexual assault on a child can result in both short-term and long-term harm, including in later life. Psychological, emotional, physical, and social effects include , , , , poor , dissociative and anxiety disorders; general psychological distress and disorders such as , , chronic pain, sexualized behavior, school/learning problems; and behavior problems including , destructive behavior, criminality in adulthood and suicide.
The risk of lasting psychological harm is greater if the perpetrator of the sexual assault on the child is a relative (ie, ), or if threats or force are used. Incestual rape has been shown to be one of the most extreme forms of childhood trauma, a trauma that often does serious and long-term psychological damage, especially in the case of parental incest.
The term refers to holding the victim of a crime to be responsible for that crime, either in whole or in part. In the context of rape, it refers to the attitude that certain victim behaviors (such as or wearing sexually provocative clothing) may have encouraged the assault. In extreme cases, victims are said to have "asked for it" simply by not behaving demurely.
It has been proposed that one cause of victim blaming is the . People who believe that the world is intrinsically fair may find it difficult or impossible to accept a situation in which a person is badly hurt for no reason. This leads to a sense that victims must have done something to deserve their fate. Another theory entails the psychological need to protect one's own sense of invulnerability, which can inspire people to believe that rape only happens to those who provoke the assault. Believers use this as a way to feel safer: If one avoids the behaviours of the past victims, one will be less vulnerable. A global survey of attitudes toward sexual violence by the shows that victim-blaming concepts are at least partially accepted in many countries. Many of the countries in which victim blaming is more common are those in which there is a between the freedoms and status afforded to men and women.
