Older adults with excess body fat 'have lower life expectancy'

Posted on 12 August 2011

Carrying excess body fat later in life has been found to decrease life expectancy in a new study.

These results, published in the Journal of the American Geriatrics Society, contradict the previous belief that weighing a bit more in later life can stave off mortality.

The new study weighted participants at a number of points over a longer period of time than was used in previous research.

It was also found that men had a higher sensitivity to body fat than women, experiencing a greater risk of death at a BMI of 22.3, compared to 27.4 for women.

"When you control for confounding by disease-related weight loss, overweight and obesity remain a risk for persons over the age of 75," said lead author Dr Pramil N Singh.

"This suggests that elderly individuals of normal weight should continue to maintain their weight."

In other news, obesity increases the risk of mortality in breast cancer patients, according to research presented at The Endocrine Society's 93rd Annual Meeting in Boston.
