[Impact of immunization measures by the Family Health Program on infant mortality from preventable diseases in Olinda, Pernambuco State, Brazil].
This article analyzes the impact of the Family Health Program (FHP) on infant health in Olinda, Pernambuco State, Brazil, evaluating immunization and infant mortality from vaccine-preventable diseases. A time-series study was conducted with data from the principal health information systems, analyzing indicators before and after implementation of the FHP in 1995. The independent variable was year of birth, related to degree of population coverage by the FHP. Three periods were analyzed: 1990-1994 (prior), 1995-1996 (implementation phase: 0 to 30% coverage), and 1997-2002 (intervention: coverage of 38.6% to 54%). Trends in the indicators were analyzed by simple linear regression, testing significance with the t test. During the implementation period there was an increase in all the vaccination coverage rates (176% BCG, 223% polio, 52% DPT, 61% measures) and a decrease in infant mortality from preventable diseases (12.7 deaths/year), even without a decrease in absolute poverty in the municipality or an increase in either coverage by the public health care system or the sewage system. Improvement in the indicators demonstrates the effectiveness of FHP actions in the municipality.
