Income shifts prompt BMI changes in married couples.

Study: When one spouse's income rises, the other's BMI tends to fall, challenging the 'trophy wife' trope.

Why it matters

  • Challenges the traditional 'trophy wife' concept, showing mutual adjustments in marriages.
  • Highlights how economic shifts can influence physical health and attractiveness within relationships.

By the numbers

  • 3,744 heterosexual, dual-earner married couples studied over 20 years.
  • BMI and physical exercise frequency were key measures.
  • When one spouse's relative income rose, the other's BMI fell.

The big picture

  • Marriage involves continuous negotiation of status and attractiveness.
  • Economic parity is matched by aesthetic parity, with both genders investing in appearance.

What they're saying

  • Comments suggest more money could mean more time for exercise and better diet.
  • Criticism of BMI as a measure, especially for muscular individuals.
  • Personal anecdotes support the idea that financial freedom can lead to better health habits.

Caveats

  • Data collected every two years, missing short-term changes.
  • BMI is a limited measure of attractiveness.
  • Study limited to straight dual-earner couples.

What’s next

  • Further research could explore other types of relationships and more diverse samples.
  • Understanding these dynamics could help in relationship counseling and health interventions.
