Insights

Over half of all children globally, approximately 1 billion, experienced violence in the past year. This study synthesizes data to estimate the prevalence of child violence worldwide.

Area of Science:

  • Public Health
  • Epidemiology
  • Child Development

Background:

  • Childhood violence is linked to adult mortality.
  • Understanding past-year prevalence of child violence is crucial for global initiatives.
  • The United Nations aims to end all violence against children.

Purpose of the Study:

  • To systematically review population-based surveys on past-year violence against children.
  • To synthesize evidence and generate minimum regional and global prevalence estimates.
  • To inform global efforts to end child violence.

Main Methods:

  • Systematic review of population-based surveys.
  • Searched multiple databases (Medline, PubMed, etc.) and the web.
  • Data extraction on prevalence by country, age, and type of violence (physical, sexual, emotional).
  • Triangulation approach used to synthesize data and generate minimum regional prevalences.

Main Results:

  • 38 reports provided quality data for 96 countries.
  • Minimum of 50% of children in Asia, Africa, and Northern America experienced past-year violence.
  • Globally, over half of all children (1 billion, ages 2-17) experienced past-year violence.

Conclusions:

  • Triangulation yielded minimum prevalence estimates due to data variations.
  • Expanded population-based surveillance is essential for effective prevention.
  • Urgent investment in action is needed, aligning with the UN 2030 Sustainable Development Agenda.

Bullying02:04

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Relative Risk01:12

Relative Risk

Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Group Design02:01

Group Design

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
