Difficulty: MediumPreventive Care and Immunizations

During routine well-child care, clinicians follow standardized periodicity schedules to ensure appropriate preventive screening for asymptomatic children and adolescents. Arrange the following universal preventive screening assessments in chronological order, starting with the earliest recommended age of initial administration to the latest.

  1. 1Universal screening for autism spectrum disorder (ASD) using a standardized tool
  2. 2Initial universal screening for dyslipidemia with a lipid profile
  3. 3Initiation of universal annual screening for major depressive disorder
  4. 4Universal routine screening for human immunodeficiency virus (HIV) infection

Answer

The correct sequence for the initial administration of these universal screenings is: Autism spectrum disorder (18 months), Dyslipidemia (9-11 years), Major depressive disorder (12 years), and HIV infection (15-18 years).
Preventive care guidelines emphasize specific universal screening milestones. Autism screening is performed in early toddlerhood (18 and 24 months). Dyslipidemia screening is universally performed in late childhood (9-11 years) before pubertal lipid shifts. Depression screening is initiated in early adolescence (12 years) and performed annually thereafter. Finally, a one-time universal HIV screen is recommended in mid-to-late adolescence (15-18 years).

Step-by-Step Solution

1
Determine the initial age for universal autism spectrum disorder (ASD) screening.
ASD screening is universally conducted at 18 and 24 months.
Early identification and intervention for neurodevelopmental delays significantly improve long-term outcomes.
2
Determine the initial age for universal dyslipidemia screening.
Lipid screening is universally conducted once between 9 and 11 years of age.
Targeted screening misses a significant portion of children with familial hypercholesterolemia. Screening is done before puberty because normal pubertal changes can falsely lower HDL and raise triglycerides.
3
Determine the initial age for universal depression screening.
Depression screening begins at age 12 years.
The incidence of major depressive disorder rises sharply during adolescence, making annual screening critical starting at this age.
4
Determine the age for universal HIV screening.
HIV screening is conducted at least once between 15 and 18 years of age.
This captures the population as they enter peak years of sexual debut, recognizing that relying solely on risk-based screening misses many infected youth.
