Methods: we performed a community-based study of people aged 70 years and over in Hai, Tanzania. Participants underwent disability assessment using the culturally non-specific Barthel index (BI), and also clinical assessment for neurological disorders and memory problems. Results: in 2,232 participants, the age-adjusted prevalence of severe disability (BI < 15) was 3.7% (95% CI: 2.9-4.5) and the age-adjusted prevalence of moderate disability (BI: 15-18) was 6.2% [95% confidence interval (CI): 5.2-7.2]. Increasing age, female gender, memory problems and the presence of neurological disorders were all independent predictors of the presence of disability. Conclusion: in this study, the average disability level was lower than seen in most high-income countries. This may reflect increased mortality from disabling disease in low-income countries. Disability is likely to increase as the population of low-income countries ages and disease survival improves.
