Successful ageing in Singapore: prevalence and correlates from a national survey of older adults

INTRODUCTION@#The current study aimed to estimate the overall prevalence and sociodemographic correlates of successful ageing, as defined by Rowe and Kahn, among a national sample of multiethnic adults aged 60 years and older in Singapore.@*METHODS@#Data from older adults who participated in the Well-being of the Singapore Elderly study was analysed. Successful ageing was defined with five indicators: no major diseases; no disability; high cognitive functioning; high physical functioning; and active engagement with life.@*RESULTS@#The prevalence of successful ageing was 25.4% in this older population. Older adults aged 75-84 years and ≥ 85 years had 0.3 times and 0.1 times the odds of successful ageing, respectively, than those aged 60-74 years. Compared to older adults of Chinese ethnicity, those of Malay (odds ratio [OR] 0.6) and Indian (OR 0.5) ethnicities were less likely to be associated with successful ageing. Older adults with lower education levels, who had no formal education (OR 0.2), some schooling but did not complete primary education (OR 0.4) or only primary education (OR 0.5), had lower odds of ageing successfully than those with tertiary education.@*CONCLUSION@#Older adults in Singapore tend to have much more active engagement with life as compared to their counterparts from other countries. Further research into this population is needed, both in terms of qualitative research to gain a better understanding of successful ageing from the older adult's perspective, as well as longitudinal studies that explore behavioural determinants of successful ageing.

Prevalence and correlates of diabetes mellitus and dyslipidaemia in a long-stay inpatient schizophrenia population in Singapore

<p><b>INTRODUCTION</b>Patients with schizophrenia have shorter life expectancy and one of the main causes of death is cardiovascular disease (CVD). Modifiable risk factors for CVD include diabetes mellitus (DM) and dyslipidaemia. This study aimed to establish: (a) the prevalence and correlates of DM and dyslipidaemia; (b) the proportion of those whose condition was well controlled; and (c) the incidence of undiagnosed DM and dyslipidaemia in a long-stay inpatient schizophrenia population.</p><p><b>METHODS</b>Data was collected to assess the physical health status of 110 inpatients with schizophrenia who had been in hospital for over one year. Information on sociodemographic characteristics, diagnosis of physical and mental illnesses, and current medications was obtained from their medical records. The overall prevalence of DM and dyslipidaemia was based on diagnosis in the medical records, current medications and fasting blood test results.</p><p><b>RESULTS</b>The patient group was predominantly male (85.5%), with a mean age of 55.9 ± 9.9 (range 25-90) years. Overall prevalence of DM and dyslipidaemia was 19.1% and 62.7%, respectively. Multivariate logistic regression analysis showed that Malay (odds ratio [OR] 14.97) and Indian (OR 25.71) patients were significantly more likely to have DM when compared to Chinese patients.</p><p><b>CONCLUSION</b>In comparison to the general population, the prevalence of DM and dyslipidaemia was found to be higher in inpatients with schizophrenia. However, the two chronic illnesses were well controlled in inpatients and few were undiagnosed, perhaps due to the regular monitoring, supervised diet and regular physical activities arranged for inpatients in the long-stay inpatient wards.</p>

Comorbid Diabetes and Depression among Older Adults - Prevalence, Correlates, Disability and Healthcare Utilisation

<p><b>INTRODUCTION</b>The objectives of this current study were to: 1) examine the prevalence and correlates of diabetes mellitus (DM) among older adults (aged 60 years and above) in a multi-ethnic population; 2) examine the prevalence and correlates of comorbid DM and depression among them; and 3) assess the effect of comorbid depression on disability, cognition and healthcare utilisation.</p><p><b>MATERIALS AND METHODS</b>Data for the current study came from the Well-being of the Singapore Elderly (WiSE) study; a single phase, cross-sectional survey conducted among Singapore residents aged 60 years and above. A total of 2565 respondents completed the survey; depression was assessed using the Automated Geriatric Examination for Computer Assisted Taxonomy (AGECAT) while a diagnosis of DM was considered if respondents stated that a doctor had diagnosed them with DM.</p><p><b>RESULTS</b>DM was reported by 25.5% of the population. The prevalence of depression was significantly higher in those diagnosed with DM than those without DM (6% vs 3%). After adjusting for sociodemographic correlates, smoking and other chronic conditions, DM remained significantly associated with depression and subsyndromal depression. However, after including measures of functioning and cognitive impairment as covariates, DM was not significantly related to depression and subsyndromal depression. Those with comorbid DM and depression were more likely to be of Indian and Malay ethnicity, aged 75 to 84 years (versus 60 to 74 years) and widowed.</p><p><b>CONCLUSION</b>Given the significant association of certain sociodemographic groups with comorbid depression among those with DM, targeted interventions for prevention and early diagnosis in these groups should be considered.</p>

Disability in Singapore's Elderly Population

<p><b>INTRODUCTION</b>Disability increases an individual's dependence and negatively impacts their physical, mental, and social functioning. The current study aims to establish the prevalence and risk factors of disability in Singapore's population.</p><p><b>MATERIALS AND METHODS</b>Data was extracted from the Well-being of the Singapore Elderly (WiSE) study. This cross-sectional study recruited participants aged 60 years and above (n = 2421) who were representative of Singapore's multiethnic population. We used the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 to assess the severity of disability in our sample while establishing its associations and correlations with cognitive levels, sociodemographic variables, and chronic illness.</p><p><b>RESULTS</b>Cognitive deficits, old age, female gender, Malay and Indian ethnicity, lack of education, retired or homemaker status, presence of chronic illness (specifically stroke, heart problems, depression, and dementia) were found to be significantly associated with disability in Singapore's elderly population. As hypothesised, participants with deficits in cognition were more likely to indicate higher WHODAS scores.</p><p><b>CONCLUSION</b>The findings highlighted specific factors associated with disability in this multiethnic population. The identification of these factors would lead the way to the development of appropriate interventions.</p>

Prevalence of Depression among Older Adults-Results from the Well-being of the Singapore Elderly Study

<p><b>INTRODUCTION</b>Depression is a significant public health issue across all sociodemographic groups and is identified as a common and serious mental health problem particularly among the older adult population. The aims of the current study were to determine the prevalence of depression and subsyndromal depression among older adults in Singapore.</p><p><b>MATERIALS AND METHODS</b>The Well-being of the Singapore Elderly (WiSE) study was a comprehensive single phase, cross-sectional survey. Stage 1 Geriatric Mental State-Automated Geriatric Examination for Computer Assisted Taxonomy (GMS-AGECAT) depression syndrome was used for this analysis. Association of depression and subsyndromal depression with sociodemographic characteristics, social support as well as comorbidity with chronic physical illnesses and quality of life was assessed.</p><p><b>RESULTS</b>The prevalence of GMS-AGECAT depression and subsyndromal depression was 3.7% and 13.4%, respectively. The odds of depression were significantly higher among those aged 75 to 84 (2.1) as compared to those aged 60 to 74 years and in those who had a history of depression diagnosis by a doctor (4.1). The odds of depression were higher among those of Indian and Malay ethnicities (5.2 and 3.2 times, respectively) as compared to those of Chinese ethnicity. Those with depression and subsyndromal depression were associated with more disability, poorer life satisfaction, and medical comorbidities.</p><p><b>CONCLUSION</b>Our study suggests that the prevalence of depression seems to have decreased as compared to a decade ago wherein the prevalence of depression was estimated to be 5.5%. This positive trend can be ascribed to concerted efforts across various disciplines and sectors, which need to be continually strengthened, monitored and evaluated.</p>
