The aim of this study was to examine the prevalence of probable psychiatric disorders diagnosed during pregnancy and related sociodemographic causative factors among 712 women between the 16th and 36th week of pregnancy receiving prenatal care in 18 basic health units in Porto Alegre and Bento Gonçalves in southern Brazil. PRIME-MD was used to assess mental disorders. The prevalence of probable mental disorder occurred in 41.7% of the women. The most prevalent diagnosis was major depressive disorder (21.6%), followed by generalized anxiety disorder (19.8%). A multivariate analysis showed that the factors most significantly associated with a probable psychiatric disorder were: the fact that the pregnant woman did not work or study: PR = 1.25 (95%CI: 1.04-1.51);the fact that the pregnant woman did not live with her spouse: PR = 1.24 (95%CI: 1.01-1.52);the fact that the pregnant woman had two or more children: PR = 1.21 (95%CI: 1.01-1.46). A high prevalence of probable mental disorder was observed. The increased search for health care by pregnant women provides an opportunity for screening, diagnosing and treating these disorders under the primary health care system.
