From VOA Learning English, this is the Health & Lifestyle report.

Each year nearly three out of four children around the world experience some kind of violence.

A new report confirms that finding and another troubling development: Childhood violence is linked with violence against women. Children who see their mother being abused are more likely to be abused as an adult or become abusers themselves.

The report is called "Ending Violence in Childhood: Global Report 2017."

The study was prepared for a children's rights group called Know Violence in Childhood. The organization was launched in India three years ago.

The study found that childhood violence happens nearly everywhere -- in rich and poor countries alike. It affects an estimated 1.7 billion children every year.

This violence includes fighting or bullying -- the mistreatment or abuse of someone by a stronger or more powerful individual. It can also include sexual abuse, sexual violence and physical punishment, both at home and in school. The researchers did not include violence from war and other events.

Ramya Subrahmanian is executive director of Know Violence in Childhood. She said that children experience emotional and physical punishment at young ages -- some from as early as two years of age.

She adds that violence is a learned behavior that comes from deep, long-held cultural values. For example, in some societies, beating is a form of discipline.

Economic cost of childhood violence

The researchers say there is also an economic cost to society when children experience violence. They found that children who experience violence at home are more likely to miss school or even leave school and never return. They are less likely to get an education and succeed in life.

Know Violence in Childhood reports that up to 8% of the world's Gross Domestic Product (GDP) is spent on repairing the damage caused by childhood violence. GDP is usually defined as the total value of all goods and services. The report notes that even with such a high cost, governments fail to invest in policies that could stop the causes of childhood violence.

The group's website explores ways to end the violence.

It reports that experts say the first step is to speak out about violence against children. Keeping silent only increases the chance that violence will continue. The experts also say that it is important to educate caregivers and empower children to be strong and resilient.

The report says that anti-violence education needs to be included in school systems, community programs and in health services.

And that's the Health & Lifestyle report.
