Temporary and persistent overweight and long-term labor market outcomes

Area of Science:

• Economics
• Sociology
• Public Health

Background:

• Childhood and adolescent obesity are significant public health concerns.
• Early life factors can have lasting impacts on adult socioeconomic outcomes.
• Understanding the long-term consequences of overweight is crucial for policy development.

Purpose of the Study:

• To investigate the association between the duration of being overweight in early adulthood and subsequent long-term labor market outcomes.
• To differentiate the labor market effects of persistent overweight status between men and women.
• To control for genetic and family environment factors using twin data.

Main Methods:

• Utilized longitudinal data from fraternal and identical twins, including weight measurements from 1975, 1981, and 1990.
• Linked twin data with register-based administrative data on earnings and employment from 1990 to 2009.
• Employed an empirical strategy leveraging twin comparisons to isolate the effects of overweight, controlling for shared genes and household environment.

Main Results:

• Persistent overweight status in early adulthood is negatively associated with long-term earnings for both genders.
• For women, this negative association is primarily driven by reduced labor market attachment.
• For men, the negative association is primarily driven by lower annual earnings.

Conclusions:

• The duration of being overweight during early adulthood has significant, detrimental long-term labor market consequences.
• The mechanisms through which overweight impacts labor market outcomes differ between men and women.
• Findings highlight the importance of addressing early adulthood weight status for future economic well-being.
