Respiratory burden ‘high in aging population’

The research, presented Monday (Sept. 3, 2012) at the European Respiratory Society’s annual Congress in Vienna, aimed to investigate the respiratory health of people at the extremes of the ageing population.

The analysis revealed that overall, 20% of men and 21% of women had either asthma or COPD. 59% of men and 50% of women showed airflow obstruction when they undertook a spirometry test to measure lung function.

People aged 85 years and over are the fastest growing age group worldwide. As many chronic diseases are more common in older people, population ageing results in a higher number of people living with chronic conditions. Chronic obstructive pulmonary disease (COPD) is one of the major illnesses affecting the elderly. As more people are living longer, it is likely that the number of cases of COPD will rise in the coming years.

Researchers from the UK aimed to investigate the current burden of respiratory conditions in the elderly population. The research was conducted as part of the Newcastle 85+ study, a 5-year longitudinal study assessing and following the health and vitality of members of the general population from the year they reach 85 years of age.

The study includes comprehensive demographic, physiological, clinical and biological assessments of health and vitality. For this paper, the research team worked with 845 people aged 85years and over from the UK.

The initial results of the study suggest a significant burden of respiratory problems in a very elderly population.

Lead author, Therese Small, from the Freeman Hospital and Newcastle University in the UK, said:  “Over the next few years, it will be crucial for healthcare professionals to understand the problems the ageing population will face. The results provide a novel insight into the future healthcare needs of this rapidly growing population.

“Our results confirm a significant prevalence of obstructive spirometry in the 85+ population, further evaluation of this unique dataset will allow us to examine how much of this is attributable to healthy ageing of the lungs and how much to the airways disease in this population of very old people.”
