        Older adults with a poor sense of smell may die sooner than those who have a better sense of smell,a new study suggests.

        The study was a project of researchers in the United States that wasongoingfor over 13 years.They asked nearly 2,300 men and women toidentify12 common smells.All thesubjectswere from 71 to 82 years of age.The researchers gave the adults scores,from zero to as high as 12,based on how many smells they identified correctly. During 13 years of follow-upinvestigation,over 1,200 of the subjects died.

        When the study waslaunched,none of the adults were weak.They could walk a little under half a kilometer,climb 10 steps and independently complete daily activities.In the latest findings,the researchers noted that those with a weak nose were 30 percent more likely to die by year 13 than people with a good sense of smell.

        Honglei Chen was the lead writer of a report on the study.He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good-to-excellent health.This suggests that a poor sense of smell is an early andsensitivesign of worsening health before it is recognizable in medical tests.

        People who took part in the study in good health were 62 percent more likely to die by year 10 if they had a poor sense of smell.But smell did not appear tomake ameaningfuldifferencein death rates for people who were in a poor state of health at the start of the study.With a poor sense of smell,people were more likely to die of brain and heart diseases,but not of cancer or breathing disorders.

        The results also suggest that a poor sense of smell may be an early warning of poor health in older age.These often signal the beginning of a weakening of the mind or body.

        The connection between a poor sense of smell and mortality risk did not appear to change based on sex or race.It also did not change based on individuals’other qualities,such as the way they live or ongoing health conditions.
