Weight can af­fect life ex­pectancy more

Glamorgan Gazette - - Your Views -

PEO­PLE who are over or un­der­weight may be at greater risk of death than pre­vi­ous ex­pected, sci­en­tists have said.

Those with a body mass in­dex (BMI) of 21- 25 were as­so­ci­ated with the low­est risk of dy­ing from can­cer and heart dis­ease, ac­cord­ing to peer-re­viewed anal­y­sis of 3.6 mil­lion peo­ple and nearly 370,000 deaths.

The Lon­don School of Hy­giene and Trop­i­cal Medicine, which led the new study, said that while BMI – a mea­sure of body fat – has long been a key in­di­ca­tor of health, the find­ings shine new light on the ex­tent to which be­ing over or un­der a cer­tain BMI mea­sure­ment could in­crease sus­cep­ti­bil­ity to a shorter life ex­pectancy.
