Health Screenings for 18-Year-Olds

Cardiovascular Screening

• The USPSTF strongly recommends universal screening for hypertension starting at age 18 with a Grade A recommendation, as hypertension screening prevents premature death, myocardial infarction, renal insufficiency, and stroke 1
• Screen every 2 years if blood pressure is <120/80 mm Hg, and annually if systolic BP is 120-139 mm Hg or diastolic BP is 80-89 mm Hg 2

Mental Health and Behavioral Screening

• The American Academy of Pediatrics recommends screening annually for depression starting at age 11 and continuing through age 21, addressing suicide as a leading cause of death in adolescents and young adults 3
• Use the CRAFFT screening questionnaire to assess alcohol and drug use in adolescents and young adults, as this structured approach improves detection rates compared to unstructured questioning 3

Sexual Health Screening

• Screen for HIV infection at ages 16-18 years, as one in four new HIV infections occurs in persons aged 13-24 years, with 60% unaware of their infection 3
• Sexually transmitted infection screening should be performed based on sexual activity and risk assessment 3
• Do not screen for cervical dysplasia until age 21, regardless of sexual activity, representing a shift from previous recommendations that started screening earlier 3

Vision Screening

• At age 18, transition to risk-based vision assessment rather than routine screening, as evidence shows fewer new vision problems develop in low-risk young adults 3
• Universal visual acuity screening is not necessary at this age unless risk factors are present 3

Anemia Screening

• Routine hematocrit or hemoglobin screening is not recommended at age 18 unless specific risk factors are present, such as heavy menstrual bleeding, restrictive diets, or chronic disease 3

Common Pitfalls

• Avoid over-screening for conditions without evidence-based recommendations at this age, such as routine lipid panels in low-risk individuals or cervical cancer screening before age 21 3
• Do not rely on passive questioning for behavioral health risks—use validated screening tools like CRAFFT for substance use 3
