Health Center for Children Age 13-18
Top health conditions, risk factors, and healthy living information by age and gender for those living in the United States based on government data.
Accidents
Accidents are the most common cause of death in children 14 years old and younger. In fact, accidents cause more childhood deaths than diseases, drugs, or violence.
ADHD
ADHD is a problem with inattentiveness, over-activity, impulsivity, or a combination. For these problems to be diagnosed as ADHD, they must be out of the normal range for the child's age and development.
Allergies
An allergy is an exaggerated immune response or reaction to substances that are generally not harmful.
Asthma
Asthma is a chronic condition in which narrowing of the passages from the lungs to the nose and mouth (airways) leads to difficulty breathing. These changes commonly occur in response to changes in the environment, including weather, allergens (such as dog or cat dander, mold, or dust), foods, or respiratory infections (colds).
Depression
Adolescent depression is a disorder occurring during the teenage years marked by persistent sadness, discouragement, loss of self-worth, and loss of interest in usual activities.
Diabetes
Diabetes is a life-long disease marked by high levels of sugar in the blood. It can be caused by too little insulin (a hormone produced by the pancreas to regulate blood sugar), resistance to insulin, or both.
Drug and Alcohol Use
Drug dependence (addiction) is compulsive use of a substance despite negative consequences which can be severe; drug abuse is simply excessive use of a drug or use of a drug for purposes for which it was not medically intended.
Eating Disorders
Eating disorders are grouped into three categories: refusing to maintain a minimally normal body weight (anorexia nervosa), bingeing and purging (bulimia nervosa), and bingeing without purging (binge eating disorder).
Obesity
More than half of the U.S. population is overweight. But being obese is different from being overweight.
Sexually Transmitted Diseases
Safe sex means taking precautions during sex that can keep you from getting a sexually transmitted disease (STD), or from giving an STD to your partner. These diseases include genital herpes, genital warts, HIV, Chlamydia, gonorrhea, syphilis, hepatitis B and C, and others.
