Health officials are currently investigating a “significant decline” in life expectancy across the country.
An email sent to Public Health England by Darwen Council’s director of public health, Dominic Harrison, said: “The council had seen a sustained reduction in life expectancy.”
He said reductions in life expectancy such as this are “extremely unusual.”
Figures suggest a women’s life expectancy, which stood at 85, has fallen in recent years.
The email, sent before Christmas and seen by the Health Service Journal, said: “In Blackburn and Darwen there have been reductions for both men and women, as well as some signs of a reduction in life expectancy for men at 65.”
The email was described as an “alert” and calls for a national review to analyse “the causes and developing local/national recovery plans.”
