Prevalence of stroke, risk factors, disability and care needs in older adults in Singapore: results from the WiSE study

Objectives

The aims of the present study were to establish the prevalence of stroke, and to explore the association between stroke prevalence and sociodemographic and health factors, disability, cognitive functioning and care needs among older adult residents in Singapore.

Setting

Data were drawn from the Well-being of the Singapore Elderly study—a cross-sectional epidemiological survey conducted from 2012 to 2013 on older adults living in Singapore.

Participants

Participants were Singapore residents (citizens and permanent residents) 60 years and above who were living in Singapore during the survey period . Older adult residents who were institutionalised were also included in this study. Those who were not living in Singapore or who were not contactable were excluded from the study. The response rate was 65.6 % (2565/3913). A total population sample of 2562 participants completed the survey. Participants comprised 43.6% males and 56.4% females. The sample comprised 39.4% Chinese, 29.1% Malay, 30.1% Indian and 1.4% other ethnicities .

Primary and secondary outcome measures

History of stroke, along with other health and mental health conditions, disability and cognitive functioning, were determined by self-report.

Results

Weighted stroke prevalence was 7.6% among older adults aged 60 and above. At a multivariate level, Malay ethnicity (OR 0.41, p=0.012, 95% CI 0.20 to 0.82), hypertension (OR 4.58, p=0.001, 95% CI 1.84 to 11.40), heart trouble (OR 2.45, p=0.006, 95% CI 1.30 to 4.63), diabetes (OR 2.60, p=0.001, 95% CI 1.49 to 4.53) and dementia (OR 3.57, p=0.002, 95% CI 1.57 to 8.12) were associated with stroke prevalence.

Conclusions

Several findings of this study were consistent with previous reports. Given that Singapore's population is ageing rapidly, our findings may indicate the need to review existing support services for stroke survivors and their caregivers. Future research could investigate the association between various sociodemographic and health conditions and stroke prevalence to confirm some of the findings of this study.
