Psychology I / Life Cycle and Health
Practice question · Put in order

Order the lifespan chain showing why health psychologists emphasize early prevention.

Hints
  1. Follow the lifespan in order and note that each stage's exposures carry forward.
  2. The cumulative logic is why intervening early beats waiting for disease to appear.
Show the answer
  1. Health habits and beliefs are established in childhood through family modeling.
  2. Adolescence adds new exposures as risk-taking spikes.
  3. Decades of accumulated behavior and exposure build up through adulthood.
  4. Chronic disease emerges in adulthood as the cumulative result.
  5. Health in older age reflects a lifetime of accumulated exposure.
Why

Habits form in childhood, adolescence adds exposures, decades of accumulation follow, chronic disease emerges in adulthood, and older-age health reflects the whole accumulated history. Because health behavior is cumulative, prevention pays most when it starts early.
