Two in Three Young Europeans Faced Childhood Hardship, WHO Finds

Childhood hardship is far more common than many realise. A major new study finds that more than two in three young adults across the European Union, Iceland and Norway experienced at least one adverse childhood experience.

The WHO/Europe findings, released on October 6, 2026, link greater exposure to childhood adversity with poorer mental health, lower quality of life and worse socioeconomic outcomes in young adulthood.

A huge survey

Researchers analysed responses from more than 26,000 people aged 18 to 30. Data were collected between November 2025 and January 2026 through national survey panels.

The study assessed nine forms of adversity, including abuse, neglect and household dysfunction such as domestic violence or growing up with a family member struggling with mental illness or substance use.

Stark findings

More than one in five young adults reported four or more adverse experiences. Among them, 76.3 percent said they had needed professional mental health support in the past year, compared with 36.7 percent of those reporting no adversity.

People with four or more adverse experiences were six times more likely to report experiencing violence and ten times more likely to report perpetrating violence as young adults. They were also around eight times more likely to report childhood cyberbullying.

A call for action

Health experts say the results highlight the urgent need for early intervention and trauma-informed care. Preventing childhood adversity and supporting affected families could improve mental health for an entire generation.

What counts as adversity

The study measured nine types of adverse childhood experiences. These included physical, emotional and sexual abuse, physical and emotional neglect, and household problems such as domestic violence, parental separation, or living with someone with mental illness or addiction.

Experiences often cluster together. A child facing one form of adversity is more likely to face others. The cumulative burden matters: each additional adversity further raises the risk of later problems.

Breaking the cycle

Experts stress that adversity does not determine destiny. Supportive relationships with even one caring adult can buffer children against harm. Schools, youth clubs and mentoring programmes all play protective roles.

Policymakers are urged to invest in family support services, affordable childcare and mental health care for young people. Early help costs far less than dealing with crises later.

The full WHO/Europe report includes recommendations for governments, schools and health services. It calls for better training for teachers to spot signs of adversity, more school counsellors and stronger links between child protection and mental health services across Europe.
