In a total of 443 pregnancies with available date of HIV diagnosis, 118 were characterized by a previously undetected HIV infection (26\u00b76%, 95% CI 22\u00b75\u201330\u00b78). The following factors were independently associated with this occurrence in a multivariate analysis (adjusted odds ratios; 95% CIs): foreign nationality (5\u00b71, 2\u00b78\u20139\u00b73); no pre-conception counselling (35\u00b79, 4\u00b78\u2013266\u00b71); first pregnancy (2\u00b71, 1\u00b72\u20134\u00b70); asymptomatic status (6\u00b78, 1\u00b75\u201330\u00b76). Women with previously undetected infection started antiretroviral treatment significantly later during pregnancy (<jats:italic>P<\/jats:italic>&lt;0\u00b7001). Missed diagnosis was responsible for one case of transmission. A high rate of previously undetected HIV infection was observed. This suggests a good HIV detection during pregnancy, but also the need to reinforce HIV testing strategies among women of childbearing age. We identified some determinants which may be considered for intervention measures.<\/jats:p>","DOI":"10.1017\/s0950268806006066","type":"journal-article","created":{"date-parts":[[2006,3,2]],"date-time":"2006-03-02T13:46:51Z","timestamp":1141307211000},"page":"1120-1127","source":"Crossref","is-referenced-by-count":36,"title":["Diagnosis of HIV infection in pregnancy: data from a national cohort of pregnant women with HIV in Italy"],"prefix":"10.1017","volume":"134","author":[{"given":"M.","family":"FLORIDIA","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"RAVIZZA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"TAMBURRINI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"ANZIDEI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"TIBALDI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"MACCABRUNI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"GUARALDI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"ALBERICO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"VIMERCATI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.
