Background: studies of prevalence of congenital defects allow assessing the results of programs and strategizing.
Objective: to describe the impact of prenatal diagnosis programs in the incidence of congenital defects at birth in the last four years in Las Tunas province.
Methods: a retrospective and descriptive study of the results of prenatal diagnosis and its impact on the incidence of congenital defects at birth was carried out. The records of congenital defects of the Provincial Genetics Network of Las Tunas during the years 2012 to 2015 were checked.
Results: the province registered a total of 884 congenital defects, 4 % of them were live births, for an adjusted prevalence of 43,2 per 1000 live births; Puerto Padre and Menéndez municipalities exceeded the provincial average, with 67,6 and 60,2 respectively; 180 cases out of all the congenital defects were discontinued, with the interruption/prenatal diagnosis rate of 0,48 and the interruptions rate of 8,8 per each 1000 live births; diagnosis predominated between 20 and 24 weeks, with 183 defects for 49,5 %; renal system defects prevailed. The infant mortality rate for congenital defects has remained at 0,6 deaths per each 1000 live births.
Conclusions: there is a reduced incidence of congenital defects at birth, with a decreasing tendency in infant mortality because of this cause, parallel to the general infant mortality. Renal congenital defects prevailed, and Puerto Padre and Menéndez municipalities showed the highest incidence.Downloads
