This study was designed to explore prevalence and correlates of selfreported
loneliness and to investigate whether loneliness predicts mortality among
older adults (aged 65 or above) in Latin America, China and India.
The study investigated population-based cross-sectional (2003-2007) and
longitudinal surveys (follow-up 2007-2010) from the 10/66 Dementia Research Group
project. Poisson regression and Cox regression analyses were conducted to analyse
correlates of loneliness and its association with mortality.
Results: The standardised prevalence of loneliness varied between 25.3 and 32.4% In
Latin America and was 18.3% in India. China showed a low prevalence of loneliness
(3.8%). In pooled meta-analyses, there was robust evidence to support an association
between loneliness and mortality across Latin American countries (HR = 1.13, 95% Cl
1.01-1.26, I2 = 10.1%) and China (HR = 1.58, 95% Cl 1.03-2.41), but there were no
associations in India. Our findings suggest potential cultural variances may exist in the concept of
loneliness in older age. The effect of loneliness upon mortality is consistent across different
cultural settings excluding India. Loneliness should therefore be considered as a potential
dimension of public health among older populations.
