SOARES, Gerlania Maria Martins de Melo et al. Socio-demographic and clinical factors of leprosy cases associated with the performance of the evaluation of their contacts in Ceará, Brazil, 2008-2019. Epidemiol. Serv. Saúde [online]. 2021, vol.30, n.3, e2020585.  Epub Aug 11, 2021. ISSN 1679-4974.


To analyze the effect of sociodemographic and clinical characteristics of new leprosy cases as determinants in the performance of the evaluation of their contacts


This was a cross-sectional study, with a temporal approach to the evaluation indicator of 100% of contacts examined of each new case (NC) registered in the state of Ceará, Brazil, on the Notifiable Diseases Information System (SINAN), in 2008-2019. Logistic regression was used to estimate odds ratio (OR) with 95% confidence intervals (95%CI). The temporal trends were analyzed using joinpoint regression.


23,675 NCs, 65.4% with contacts examined were analyzed. It was less likely to evaluate 100% of the registered contacts when the new cases were multibacillary (OR=1.19 - 95%CI 1.11;1.28) and with examination of contacts as an entry mode (OR=1.71 - 95%CI 1.35;2.18). There was an increasing temporal trend of the indicator (Annual Percentage Change: 2.1 - 95%CI 1.2;3.0).


Distinct dimensions of individual and social vulnerability among new leprosy cases influenced the persistent unsatisfactory performance of the evaluation of contacts.
