A simple screening test of musculo-skeletal fitness has proved remarkably predictive of all-cause mortality in a study of more than 2000 middle-aged and older men and women. The study, performed in Brazil by Dr Claudio Gil Arajo and colleagues at the Clinimex - Exercise Medicine Clinic in Rio de Janeiro, is reported today in the European Journal of Cardiovascular Prevention.(1,2)
The test was a simple assessment of the subjects' ability to sit and then rise unaided from the floor. The assessment was performed in 2002 adults of both sexes and with ages ranging from 51 to 80 years. The subjects were followed-up from the date of the baseline test until the date of death or 31 October 2011, a median follow-up of 6.3 years.
Before starting the test, they were told: "Without worrying about the speed of movement, try to sit and then to rise from the floor, using the minimum support that you believe is needed."
Each of the two basic movements were assessed and scored out of 5, with one point being subtracted from 5 for each support used (hand or knee, for example). Subjects were thus assessed by a composite score of 0 to 10, which, for the sake of the analysis, was ranked as four categories (C1, 0 C2, 3.5.5; C3, 6.5; and C4, 8).

Over the study period 159 subjects died, a mortality rate of 7.9%. The majority of these deaths occurred in people with low test scores - indeed, only two of the deaths were in subjects who gained a composite score of 10. Analysis found that survival in each of the four categories differed with high statistical significance. These differences persisted when results were controlled for age, gender and body mass index, suggesting that the sitting-rising test score is a significant predictor of all-cause mortality; indeed, subject
