Routine physical examinations are a cornerstone of preventive health care, offering clinicians the opportunity to detect early signs of disease, update immunizations, and reinforce healthy lifestyle choices. While the specific tests and discussions during a visit can vary based on individual risk factors, the frequency with which these exams are recommended is largely driven by age. Understanding the evidence‑based intervals for each life stage helps patients and providers strike the right balance between vigilance and practicality, ensuring that health concerns are addressed promptly without unnecessary redundancy.
Infancy (0–12 Months)
Recommended Frequency:
- Newborn (within 48 hours of birth) – Initial assessment focusing on birth weight, feeding, and early screening (e.g., newborn metabolic panel).
- 1 Month – Evaluation of weight gain, feeding patterns, and early developmental milestones.
- 2, 4, 6, 9, and 12 Months – Follow‑up visits to monitor growth curves, immunization schedule, and neurodevelopmental progress.
Key Components:
- Growth monitoring: Weight, length, and head circumference plotted on WHO or CDC growth charts.
- Developmental screening: Use of tools such as the Ages and Stages Questionnaire (ASQ) to identify delays.
- Immunizations: Administration of vaccines per the CDC’s Recommended Immunization Schedule (e.g., DTaP, Hib, IPV, PCV13, Rotavirus, HepB).
- Safety counseling: Safe sleep practices, car seat use, and injury prevention.
Early Childhood (1–5 Years)
Recommended Frequency:
- Annual well‑child visits from age 1 through 5.
Key Components:
- Growth and BMI tracking: Early identification of under‑ or over‑nutrition.
- Developmental milestones: Language, motor, and social skills assessments.
- Vision and hearing screening: At least once before school entry.
- Immunizations: Completion of the primary series and booster doses (e.g., MMR, Varicella, HepA).
- Behavioral health: Screening for autism spectrum disorder (ASD) and behavioral concerns, especially at 18 months and 24 months.
School‑Age Children (6–12 Years)
Recommended Frequency:
- Annual physical exam for each school year.
Key Components:

- Lifestyle counseling: Reinforcement of weight management, physical activity, and stress reduction.
Late Middle Age (50–64 Years)
Recommended Frequency:
- Annually for most individuals, given the rising prevalence of chronic conditions and the initiation of several age‑specific screenings.
Key Components:
- Comprehensive vitals: Blood pressure, BMI, waist circumference, and pulse.

- Vision and hearing: Annual checks, given the impact on safety and quality of life.
Special Considerations Across All Ages
- Chronic disease presence: Individuals with hypertension, diabetes, chronic kidney disease, or cardiovascular disease generally require more frequent monitoring (often annually) regardless of age.
- Family history of early‑onset disease: A strong familial predisposition (e.g., colorectal cancer before age 45) may necessitate earlier or more frequent screening.
- Socio‑economic and access factors: Populations with limited healthcare access may benefit from community‑based screening programs and extended intervals when appropriate, but should still aim for the age‑based minimums.
- Pregnancy: Women who become pregnant should have a preconception visit and then trimester‑specific prenatal care, which supersedes routine adult preventive intervals during the pregnancy period.
Putting It All Together: A Practical Timeline
| Age Range | Physical Exam Frequency | Core Screening Highlights |
|---|---|---|
| 0–12 mo | 7 visits (newborn, 1, 2, 4, 6, 9, 12 mo) | Growth, developmental milestones, immunizations |
| 1–5 yr | Annually | Vision/hearing, immunizations, behavioral health |
| 6–12 yr | Annually | Height/weight, immunizations (Tdap, HPV), vision/hearing |
| 13–17 yr | Every 1–2 yr (annually if high risk) | Mental health, substance use, sexual health, HPV |
| 18–39 yr | Every 2–3 yr (annually if risk factors) | Blood pressure, lipids, glucose, cervical/ STI screening |
| 40–49 yr | Every 1–2 yr (annually if risk factors) | Blood pressure, lipids, glucose, start colorectal screening |
| 50–64 yr | Annually | Full panel of vitals, labs, cancer screens (breast, prostate, lung) |
| 65+ yr | Annually | Comprehensive geriatric assessment, vaccinations, bone health, cognitive screen |
By aligning routine physical exam intervals with these age‑specific recommendations, clinicians can efficiently allocate resources, catch disease early, and empower patients to maintain optimal health throughout the lifespan. The schedule is intentionally flexible—allowing for earlier or more frequent visits when personal or family history, lifestyle, or emerging symptoms dictate—while providing a solid, evidence‑based framework for the majority of the population.
