Which term refers to a stage of physical development used to describe puberty?

• A. Secular trend
• B. Delayed phase preference
• C. Longitudinal design
• D. Tanner stages

Answer: (D)

Tanner stages describe the progression of physical changes during puberty. They are a standard set of five stages used to categorize pubertal development based on observable characteristics like genital development and pubic hair in boys, and breast development and pubic hair in girls. This framework lets clinicians and researchers describe where a young person is in puberty and monitor how development progresses over time. The other terms refer to different concepts: a secular trend is about shifts in puberty timing across generations, a longitudinal design is a study method that follows the same individuals over time, and a term like delayed phase preference isn’t a recognized concept in this context.
