According to a Danish research, people 90 years of age today are surviving in old age having mental performance better than ever.The people who are born in the year 1915 scored much in the cognitive tests compared to the ones born one decade earlier, as according to one study.
Better intellectual stimulation and living standards might be the key factors, the experts say.Number of the people who are approaching much old age tends to be on rise globally.For instance, in US, number of people who are aged ninety and above appears to be more than just doubled in thirty years.
Chance of survival in tenth decade of the life has now gone up around 30 percent every decade for the people who were born in the years 1915, 1895 and 1905 in Denmark, place where this study was conducted.However, there’s only little research over quality of the life which people approaching such old age could be looking forward to.
Researchers, leader being University of Southern Denmark’s Prof Kaare Christensen, surveyed all the Danes who were born in the year 1905who still were alive and also living in country in the year 1998 (aged 92 to 93, 3600 people).
Their mental functioning, physical strength and the ability of carrying out the daily tasks like walking outside and inside, as well as any depression symptoms were assessed.After 12 years, they repeated study with the Danes born during 1915 (aged 94 to 95, 2509 people).
Researchers showed that the women and men born in the year 1915 did perform better than the ones born in the year 1905 according to cognitive ability as well as daily life activities, even after correction for the changes as improved education.
His colleagues and Prof Christensen said, “Our results show that the Danish cohort born in 1915 had better survival and scored significantly better on both the cognitive tests and the activities of daily living scale than the cohort born in 1905, despite being two years older at the time of assessment. This finding suggests that more people are living to older ages with better overall functioning.”
Research addresses important question whether living in advanced old age tends to be accompanied by even more years with bad health or the overall health in such old age happens to be improving.Commenting over this study, Prof Tom Kirkwood, ageing’s associate dean at the Newcastle University, said data that was from Denmark appeared encouraging.
He said that among the ones who were born in the year 1915, the cognitive function during very old age measurably is better compared to those born during 1905, even when the underlying changes as better education are considered.
In UK, most complete photo of the health in very old age does come from Newsactle eighty-five+ study that has been seeing the people born during 1921.Investigations would be repeated with the ones born decade later so giving them the chance of seeing if Danish findings do apply in the other populations.
