Energy balance

Nonagenarians had lower absolute and adjusted total energy expenditure (TEE) compared to participants aged 60-74 years, attributed to a reduction in both resting metabolic rate (RMR) and physical activity level.

Older adults may experience significant declines in energy expenditure due to reduced physical activity and metabolic rate.

Nonagenarians had lower absolute (p<.001) and adjusted (p<.007) TEE compared to participants aged 60-74 years which was attributed to a reduction in both RMR and physical activity level.
