Subjective measures of health and all-cause mortality – the Rotterdam Study
Key result
Subjectively assessed basic activities of daily living (HR 1.24 per Z-score; 95% CI 1.16-1.32) and instrumental activities of daily living independently predicted all-cause mortality.
Why the study?
Do subjective measures of health predict all-cause mortality in older adults?
Population
5538 participants aged 55 to 96 years at baseline from the Rotterdam Study
Design
Cohort
Follow-up

Implication
Subjective BADL/IADL impairment may refine mortality prognostication in older adults; extends cohort evidence on perceived function but leaves causal effects open.
Study Design
Type
Cohort (n=5,538)
Structured PICO
Do subjective measures of health predict all-cause mortality in older adults?
P
Population
5,538 adults aged 55 to 96 years from the Rotterdam Study, followed for a mean of 12.2 years to assess the association between subjective health measures and all-cause mortality.
E
Exposure
Subjective measures of health (basic activities of daily living [BADL], instrumental activities of daily living [IADL], quality of life [QoL], positive affect, somatic symptoms and negative affect)
O
Outcome
All-cause mortalityhard clinical
Main Result
Hazard Ratio: 1.24 (95% CI 1.16–1.32)
Perceived physical health (BADL and IADL) predicts all-cause mortality independently of mental health in older adults.
Cite This Study
Sajjad et al. (2017) reported a cohort. Subjective measures of health (e.g., BADL, IADL, QoL) was evaluated on All-cause mortality (HR 1.24, 95% CI 1.16-1.32). Subjectively assessed basic activities of daily living (HR 1.24 per Z-score; 95% CI 1.16-1.32) and instrumental activities of daily living independently predicted all-cause mortality.
