Among 580 subjects, 25% suffering from MB. Compared with those who did not have APD, those who experienced it had more than three-fold increased risk to be MB [adjusted hazard ratio (aHR) = 3.57; 95% confidence interval (CI) = 2.54;5.03]. Those who had not healthy baby on the first 5 days afterbirth than who had healthy baby had twice increased risk to be MB (aHR = 2.21; 95% CI = 1.34 ; 3.66). Who had husband with problem in mental health had 1.9 increased risk to be MB (aHR = 1.91; 95% CI = 1.36 ; 2.68). Stress during pregnancy had 1.6 increased risk to be MB (aHR = 1.59; 95% CI = 1.14 ; 2.25). To control MB, special attention should be paid to women who had APD history, who had unhealthy baby on 5 first days afterbirth, who had husbands’ mental health problems, and who had stress during pregnancy.
