Fatores associados à ausência de registro de nascimento em cartório localizado em maternidade do Sistema Único de Saúde, Nova Iguaçu-RJ, 2012
Objective: to analyze factors associated with births not registered at a National Health System (SUS) maternity hospital registry office in Nova Iguacu-RJ, Brazil. Methods: a cross-sectional study of data on 468 live births (LB) between June-July 2012. The dependent variable was births not registered at the registry office within 15 days following birth. Prevalence ratios (PR) and 95% confidence intervals (95% CI) were estimated using Poisson Regression. Results: 40.6% (190/468) of LB were not registered at the registry office. Non-registration was positively associated with little or no maternal schooling (PR 1.41; 95% CI 1.04-1.93), childbirth prior to hospitalization (PR 2.15; 95% CI 1.04-4.46), and mother resident in a different municipality to the hospital (PR 1.39; 95%% CI 1.03-1.89). Conclusion: mothers with little or no schooling and who do not give birth in hospital should receive guidance on birth registration.
