Health shocks and health behavior: a long-term perspective

Area of Science:

• Health Economics
• Behavioral Economics
• Public Health

Background:

• Existing research indicates health-related behaviors improve following adverse physical health shocks.
• Limited evidence exists on the long-term persistence of these behavioral changes.
• The impact of mental health shocks on health behaviors remains under-explored.

Purpose of the Study:

• To investigate the duration of health behavior changes after physical health shocks.
• To examine whether mental health shocks elicit similar behavioral responses compared to physical health shocks.
• To analyze health behavior adjustments up to fifteen years post-shock.

Main Methods:

• Utilized individual-level survey data from Germany.
• Employed regression augmented inverse-probability weighting (RAIPW).
• Incorporated machine learning prediction algorithms for comparative analysis.

Main Results:

• Physical health shocks led to immediate improvements in healthy eating and reduced smoking.
• Sports participation decreased following physical health shocks.
• Mental health shocks had a weaker immediate impact, except for increased smoking.
• Significant behavioral differences were seldom observed beyond two years post-shock.

Conclusions:

• Health behavior responses to adverse shocks are generally short-lived, rarely persisting beyond two years.
• Mental health shocks have a less pronounced effect on health behaviors compared to physical health shocks.
• Public health interventions may need to consider the transient nature of shock-induced behavioral changes.
