Insights

Body mass index predicts mortality in Black men but not White men. Midarm circumference was protective, while abdominal circumference increased mortality risk in Black men.

Area of Science:

  • Cardiovascular epidemiology
  • Anthropometry and public health

Background:

  • The Charleston Heart Study cohort provided data on Black and White men from the 1960s.
  • Previous research has explored anthropometric predictors of mortality.

Purpose of the Study:

  • To examine anthropometric measurements as predictors of all-cause and coronary heart disease mortality.
  • To investigate differences in these associations between Black and White men.

Main Methods:

  • Analysis of anthropometric data (body mass index, girths, circumference) from Charleston Heart Study participants.
  • Vital status determination through 1988 for 98% of the cohort.
  • Statistical analysis of mortality risk associated with various measurements.

Main Results:

  • Body mass index predicted all-cause and coronary heart disease mortality in Black men, but not White men.
  • In Black men, higher midarm circumference was associated with lower all-cause mortality, while higher abdominal circumference was linked to increased all-cause mortality.
  • Circumference measurements did not predict mortality in White men.

Conclusions:

  • Anthropometric predictors of mortality differ significantly between Black and White men.
  • Body mass index and specific circumference measurements are important indicators of mortality risk in Black men.
