Introduction: The incidence of twin pregna.cies ha. increa.ed significa.tly in recent deca.es. These pregna.cies require more a.tention due to their worse outcomes tha. singleton pregna.cies. Objective: To a.a.yze the cha.a.teristics a.d perina.a. outcomes of twin pregna.cies a. the Ca.ia. do Sul Genera. Hospita.. Methods: This is a.descriptive a.d retrospective study tha. included a.l births rela.ed to twin pregna.cies between Ma.ch 1998 a.d June 2018. Ma.erna. a.d perina.a. va.ia.les were a.a.yzed. Descriptive a.a.yses were ca.ried out using mea.ures of centra. tendency a.d dispersion for continuous va.ia.les (mea. a.d sta.da.d devia.ion or media. a.d interqua.tile ra.ge), a.cording to a.prior a.sessment of distribution using the Sha.iro-Wilk test, a.d a.solute (n) a.d rela.ive (n%) frequencies for ca.egorica. va.ia.les. Results: 172 pa.rs of twins/21,972 births (0.8%) were identified. There wa. a.high percenta.e of interpa.tum interva. of less tha. 12 months, a.herence a.d prena.a. visits, body ma.s index, a.d need for neona.a. intensive ca.e.
