Summary

Body fat increases with age, while fat-free body mass is maintained longer than previously thought. This study reveals age-related changes in body composition for men aged 20-79.

Area of Science:

  • Gerontology
  • Human Physiology
  • Body Composition Analysis

Background:

  • Previous research indicated significant declines in fat-free body mass (FFM) between ages 30 and 70.
  • Body weight typically increases until age 50, suggesting complex age-related body composition changes.

Purpose of the Study:

  • To investigate age-related patterns in body composition, specifically fat-free body mass and fat mass, in adult men.
  • To determine how body density and fat distribution change across different adult age groups.

Main Methods:

  • 157 men aged 20-79 years were studied, with approximately 15 men in each 5-year age group.
  • Total body composition was assessed using hydrodensitometry (underwater weighing).
  • Subcutaneous fat was measured using skinfold calipers at various body locations.

Main Results:

  • Body density decreased progressively with age, with men under 40 showing significantly higher densities than older men.
  • Fat-free body mass showed a gradual decline but no significant decrease until age 70.
  • Fat mass increased with age, with men over 40 having significantly higher total body fat than younger men.
  • Abdominal skinfold thickness increased significantly with age, indicating central fat accumulation.

Conclusions:

  • Fat-free body mass is maintained to a later age than previously reported.
  • The age-related decrease in body density is primarily attributable to an increase in body fat, particularly in the trunk region.
  • Findings highlight the importance of considering fat mass accumulation in aging men.
