"How was your health 3 years ago?" Predicting mortality in older adults using a retrospective change measure of self-rated health.

چکیده
AIM Studies have shown better predictive value of self-rated health (SRH) for mortality when prospective change in SRH is considered. However, retrospective change is more feasible and might have better sensitivity to objective health changes. This study compares the predictive value for mortality of retrospectively measured change in SRH (based on a "then-test") with current SRH and prospectively measured change in SRH. METHODS Data from two waves of the Longitudinal Aging Study Amsterdam (2001-2003 and 2005-2006 [T0 ], n=1894) were used. Retrospective change was defined as the difference between SRH at T0 ("current SRH") and SRH measured with a then-test at T0 , asking for a renewed judgement of one's health at the previous wave. Prospective change was defined as change in SRH between the two waves. We applied Cox proportional hazards analysis to predict 5-year mortality. RESULTS Having poorer current SRH significantly predicted mortality (HR poor vs very good SRH=4.42). Declined SRH was associated with higher mortality risk, but only when measured prospectively (one point decline vs no change HR=1.33; two points decline HR=1.95). After adjusting for current SRH, neither change measure predicted mortality. Results were similar in subgroups that did and did not experience incident diseases or limitations between the two waves. CONCLUSIONS Neither retrospective, nor prospective changes in SRH improved the prediction of mortality in older adults over current SRH. These results imply that using a standard single indicator for self-rated health in research or clinical practice might suffice to identify those with a high risk of future negative health outcomes.

The choice of self-rated health measures matter when predicting mortality: evidence from 10 years follow-up of the Australian longitudinal study of ageing
BACKGROUND Self-rated health (SRH) measures with different wording and reference points are often used as equivalent health indicators in public health surveys estimating health outcomes such as healthy life expectancies and mortality for older adults. Whilst the robust relationship between SRH and mortality is well established, it is not known how comparable different SRH items are in their re...

OBJECTIVES Despite the well-established association between self-rated health and mortality, research findings have been inconsistent regarding how men and women differ on this link. Using a national sample in the United States, this study compared American male and female older adults for the predictive role of baseline self-rated health on the short-term risk of mortality.

متن کاملSelf-rated health and its association with mortality in older adults in China, India and Latin America—a 10/66 Dementia Research Group study
Background empirical evidence from high-income countries suggests that self-rated health (SRH) is useful as a brief and simple outcome measure in public health research. However, in many low- and middle-income countries (LMIC) there is a lack of evaluation and the cross-cultural validity of SRH remains largely untested. This study aims to explore the prevalence of SRH and its association with m...
