The chi-square, ANOVA and multiple linear regression were used to analyze data. Results The total score of anxiety was 22.3±9.5, 24.6±9.3 and 25.4±10.6 in the first, second and third trimester of pregnancy. Totally 9%, 13% and 21% of the women had severe anxiety or scores≥ 35 in the first, second and third trimester of pregnancy respectively. Pregnant women in the third trimester significantly had more health anxiety score than the first trimester ones.
