Anxiety is now the most commonly diagnosed mental health condition among children in the United States, affecting about 11% of kids ages 3 to 17, according to 2022-2023 data from the Centers for Disease Control and Prevention.
A Growing Problem
The numbers have climbed steadily. A 2025 study in JAMA Pediatrics by Northwestern Medicine found that the proportion of U.S. children with anxiety jumped from 7.1% in 2016 to 10.6% in 2022.
Globally, a Frontiers in Psychiatry analysis reported that anxiety disorder incidence among those aged 10 to 24 rose 52% between 1990 and 2021, with a sharper climb after the COVID-19 pandemic. The National Institute of Mental Health adds that roughly one-third of U.S. adolescents will experience an anxiety disorder, with girls affected at higher rates.
Common Types of Anxiety in Children
Not all childhood anxiety looks the same. The Child Mind Institute identifies several distinct types. Generalized anxiety disorder causes kids to worry about many everyday things, from grades to family safety. Separation anxiety disorder involves intense fear about being away from a caregiver, often leading to school refusal, according to the Child Mind Institute.
Social anxiety disorder makes children fearful of being judged in front of others. Other types include selective mutism, where children cannot speak in certain settings despite talking freely at home, and specific phobias involving extreme fear of a particular object or situation.
Warning Signs Parents Should Watch For
Children often lack the words for what they feel, so anxiety tends to show up through behavior or the body. The Mayo Clinic Health System says parents should watch for:
- Frequent stomachaches, headaches, or physical complaints with no medical cause, especially before school or social events
- Difficulty falling asleep or staying asleep
- Irritability or meltdowns that seem out of proportion
- Avoidance of school, activities, or social gatherings that they once enjoyed
- Constant reassurance-seeking, such as asking the same questions repeatedly
- Withdrawal from friends, play, or hobbies
These behaviors are often mistaken for stubbornness or bad moods, but they can signal an underlying anxiety disorder.
What Causes Childhood Anxiety
There is no single cause. The CDC states that biology, temperament, trauma, and environment all play a role. Children who experience bullying, abuse, neglect, or peer rejection are at higher risk. Kids whose parents have anxiety or depression are also more prone, as generalized anxiety has about a 30% heritability rate.
Every day pressures matter too. Academic stress is a top trigger for preteens. Major life changes such as moving, divorce, or losing a loved one can shake a child's sense of safety. Increased screen time and early social media exposure have also been linked to rising anxiety symptoms, the Centers for Disease Control and Prevention said.
How Parents Can Help
The Child Mind Institute stresses that the worst thing a parent can do is help a child avoid everything that causes anxiety. Avoidance brings short-term relief but reinforces the problem over time. Instead, parents should gently encourage children to face fears at a manageable pace.
Clinicians recommend several strategies. Validate feelings without amplifying them — saying "I know you are scared, and that is okay" works better than dismissing the fear. Express confidence that your child can handle hard situations, because children pick up on calm parental reactions.
Challenge unhelpful thinking by asking questions like "Have you ever failed a test before?" Model healthy coping by managing your own stress constructively. Build confidence through age-appropriate responsibilities and praising effort over results.
When anxiety interferes with daily life, professional help is key. The CDC recommends anxiety screening for children ages 8 to 18. Cognitive behavioral therapy has proven effective, and a pediatrician can determine whether therapy, medication, or both are needed.
Children do not simply grow out of anxiety. Without support, they learn to suppress it, which can lead to panic attacks or depression later in life. Early intervention gives children the tools to build lasting resilience, as per Authentic Growth Wellness.
