Incidence and predictors of mortality among community-dwelling older adults in Malaysia: A 5 years longitudinal study
With older adults accounting for 10.7% of the Malaysian population, determining the predictors of mortality has now become crucial. Thus, this community-based longitudinal study aimed to investigate the predictors for mortality among community-dwelling older adults using a wide range of factors, inc...

With older adults accounting for 10.7% of the Malaysian population, determining the predictors of mortality has now become crucial. Thus, this community-based longitudinal study aimed to investigate the predictors for mortality among community-dwelling older adults using a wide range of factors, including clinical or subclinical. A total of 2322 older adults were interviewed and assessed by trained fieldworkers using validated structured questionnaires. The questionnaire consisted of information on socio-demographic characteristics, health status, neuropsychological and psychosocial functions, lifestyle, dietary intake and biophysical measures. The incidence rate of mortality was 2.9 per 100 person-years. Cox regression analysis indicated that advancing age (Adjusted Hazard Ratio, Adj HR = 1.044, 95% CI: 1.024-1.064), male (Adj HR = 1.937, 95% CI: 1.402-2.675), non-married status (Adj HR = 1.410, 95% CI: 1.078-1.843), smoking (Adj HR = 1.314, 95% CI: 1.004-1.721), a higher fasting blood sugar (Adj HR = 1.075, 95% CI: 1.029-1.166), a lower serum albumin (Adj HR = 0.947, 95% CI: 0.905-0.990), a longer time to complete the TUG test (Adj HR = 1.059, 95% CI: 1.022-1.098), and a lower intake of total dietary fibre (Adj HR = 0.911, 95% CI: 0.873-0.980) were the predictors of mortality in this study.
