Corporal punishment and health

23 November 2021

Key facts

  • Corporal or physical punishment is highly prevalent globally, both in homes and schools. Around 60% of children aged 2–14 years regularly suffer physical punishment by their parents or other caregivers. In some countries, almost all students report being physically punished by school staff. The risk of being physically punished is similar for boys and girls, and for children from wealthy and poor households.
  • Evidence shows corporal punishment increases children’s behavioural problems over time and has no positive outcomes.
  • All corporal punishment, however mild or light, carries an inbuilt risk of escalation. Studies suggest that parents who used corporal punishment are at heightened risk of perpetrating severe maltreatment.
  • Corporal punishment is linked to a range of negative outcomes for children across countries and cultures, including physical and mental ill-health, impaired cognitive and socio-emotional development, poor educational outcomes, increased aggression and perpetration of violence.
  • Corporal punishment is a violation of children’s rights to respect for physical integrity and human dignity, health, development, education and freedom from torture and other cruel, inhuman or degrading treatment or punishment.
  • The elimination of violence against children is called for in several targets of the 2030 Agenda for Sustainable Development but most explicitly in Target 16.2: “end abuse, exploitation, trafficking and all forms of violence against and torture of children”.
  • Corporal punishment and the associated harms are preventable through multisectoral and multifaceted approaches, including law reform, changing harmful norms around child rearing and punishment, parent and caregiver support, and school-based programming.

Overview

Corporal or physical punishment is defined by the UN Committee on the Rights of the Child, which oversees the Convention on the Rights of the Child, as “any punishment in which physical force is used and intended to cause some degree of pain or discomfort, however light.”

According to the Committee, this mostly involves hitting (smacking, slapping, spanking) children with a hand or implement (whip, stick, belt, shoe, wooden spoon or similar) 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.

Other non-physical forms of punishment can be cruel and degrading, and thus also incompatible with the Convention, and often accompany and overlap with physical punishment. These include punishments which belittle, humiliate, denigrate, scapegoat, threaten, scare or ridicule the child.

Scope

UNICEF’s data from nationally representative surveys in 56 countries 2005–2013 show that approximately 6 out of 10 children aged 2–14 years experienced corporal punishment by adults in their households in the past month. On average, 17% of children experienced severe physical punishment (being hit on the head, face or ears or hit hard and repeatedly) but in some countries this figure exceeds 40%. Large variations across countries and regions show the potential for prevention.

Apart from some countries where rates among boys are higher, results from comparable surveys show that the prevalence of corporal punishment is similar for girls and boys. Young children (aged 2–4 years) are as likely, and in some countries more likely, as older children (aged 5–14 years) to be exposed to physical punishment, including harsh forms. Physical disciplinary methods are used even with very young children – comparable surveys conducted in 29 countries 2012–2016 show that 3 in 10 children aged 12–23 months are subjected to spanking.

Most children are exposed to both psychological and physical means of punishment. Many parents and caregivers report using non-violent disciplines measures (such as explaining why the child’s behaviour was wrong, taking away privileges) but these are usually used in combination with violent methods. Children who experience only non-violent forms of discipline are in the minority.

One in 2 children aged 6–17 years (732 million) live in countries where corporal punishment at school is not fully prohibited. Studies have shown that lifetime prevalence of school corporal punishment was above 70% in Africa and Central America, past-year prevalence was above 60% in the WHO Regions of Eastern Mediterranean and South-East Asia, and past-week prevalence was above 40% in Africa and South-East Asia. Lower rates were found in the WHO Western Pacific Region, with lifetime and past year prevalence around 25%. Physical punishment appeared to be highly prevalent at both primary and secondary school levels.

Consequences

Corporal punishment triggers harmful psychological and physiological responses. Children not only experience pain, sadness, fear, anger, shame and guilt, but feeling threatened also leads to physiological stress and the activation of neural pathways that support dealing with danger. Children who have been physically punished tend to exhibit high hormonal reactivity to stress, overloaded biological systems, including the nervous, cardiovascular and nutritional systems, and changes in brain structure and function.

Despite its widespread acceptability, spanking is also linked to atypical brain function like that of more severe abuse, thereby undermining the frequently cited argument that less severe forms of physical punishment are not harmful. 

A large body of research shows links between corporal punishment and a wide range of negative outcomes, both immediate and long-term:

  • direct physical harm, sometimes resulting in severe damage, long-term disability or death;
  • mental ill-health, including behavioural and anxiety disorders, depression, hopelessness, low self-esteem, self-harm and suicide attempts, alcohol and drug dependency, hostility and emotional instability, which continue into adulthood;
  • impaired cognitive and socio-emotional development, specifically emotion regulation and conflict solving skills;
  • damage to education, including school dropout and lower academic and occupational success;
  • poor moral internalization and increased antisocial behaviour;
  • increased aggression in children;
  • adult perpetration of violent, antisocial and criminal behaviour;
  • indirect physical harm due to overloaded biological systems, including developing cancer, alcohol-related problems, migraine, cardiovascular disease, arthritis and obesity that continue into adulthood;
  • increased acceptance and use of other forms of violence; and
  • damaged family relationships.

There is some evidence of a dose–response relationship, with studies finding that the association with child aggression and lower achievement in mathematics and reading ability became stronger as the frequency of corporal punishment increased.

Risk factors

There are few differences in prevalence of corporal punishment by sex or age, although in some places boys and younger children are more at risk. Children with disabilities are more likely to be physically punished than those without disabilities. Parents who were physically punished as children are more likely to physically punish their own children.

In most of the countries with data, children from wealthier households are equally likely to experience violent discipline as those from poorer households. In contrast, in some resource-poor settings, especially where education systems have undergone rapid expansion, the strain on teachers resulting from the limited human and physical resources may lead to a greater use of corporal punishment in the classroom.

Prevention and response

The INSPIRE technical package presents several effective and promising interventions, including:

  • Implementation and enforcement of laws to prohibit physical punishment. Such laws ensure children are equally protected under the law on assault as adults and serve an educational rather than punitive function, aiming to increase awareness, shift attitudes towards non-violent childrearing and clarify the responsibilities of parents in their caregiving role.
  • Norms and values programmes to transform harmful social norms around child-rearing and child discipline.
  • Parent and caregiver support through information and skill-building sessions to develop nurturing, non-violent parenting.
  • Education and life skills interventions to build a positive school climate and violence-free environment, and strengthening relationships between students, teachers and administrators.
  • Response and support services for early recognition and care of child victims and families to help reduce reoccurrence of violent discipline and lessen its consequences.

The earlier such interventions occur in children's lives, the greater the benefits to the child (e.g., cognitive development, behavioural and social competence, educational attainment) and to society (e.g., reduced delinquency and crime).

WHO Response

WHO addresses corporal punishment in multiple cross-cutting ways. In collaboration with partners, WHO provides guidance and technical support for evidence-based prevention and response. Work on several strategies from the INSPIRE technical package, including those on legislation, norms and values, parenting, and school-based violence prevention, contribute to preventing physical punishment. The Global status report on violence against children 2020 monitors countries’ progress in implementing legislation and programmes that help reduce it. WHO also advocates for increased international support for and investment in these evidence-based prevention and response efforts.
