Prevalence, pattern, and factors associated with self-reported disability among the tribal population in Jawadhi Hills, Tamil Nadu: a census
摘要
The Jawadhi Hills region in Tamil Nadu, India, is home to predominantly tribal communities facing severe health challenges, including high infant and maternal mortality. Data on disability within these populations are limited. This study aimed to estimate the prevalence of disability and examine associated factors in this region.
MethodsA census was conducted across 395 hamlets in the Tiruvannamalai and Vellore districts. Trained field workers collected data on sociodemographic characteristics, health status, and living conditions using a structured questionnaire. Disability was assessed in individuals aged five years and above using the Washington Group Short Set on Functioning (WG-SS).
ResultsAmong 58,598 individuals aged ≥ 5 years, the prevalence of perceived functional disability, defined as “a lot of difficulty” or “unable to do” in ≥ 1 domain, or “some difficulty” in ≥ 2 domains, was 2.89% (95% CI: 2.75%–3.03%). Moderate to severe disability was most commonly reported in the domains of mobility (1.64%, 95% CI: 1.54% − 1.75%.), vision (0.89%, 95% CI: 0.81% − 0.96%), and hearing (0.70%, 95% CI: 0.63% − 0.77%). The highest prevalence of disability was observed in the ≥ 85 years age group (33.59%). Logistic regression showed that increasing age, lower educational attainment, unemployment, chronic conditions (diabetes, hypertension), caste, and poor housing conditions were significantly associated with higher odds of disability.
ConclusionsThis is the first census-based estimate of disability in a tribal population in the Jawadhi Hills. The findings reveal a notable burden of mobility-related impairments and strong links between disability and social disadvantage. The results support the integration of disability assessment into existing health programs, particularly those addressing non-communicable diseases, and call for expanded access to rehabilitation services in tribal areas.
