PND
This study is a sub-study of a larger RCT, where significant intervention effects were found on perinatal depression (PND) and perceived stress. Participants were recruited through eight maternity health clinics in Stockholm, Sweden. In this sub-study, we included altogether 80 women with increased risk for PND, and blood samples and HRV measures were available from 60 of the participants (26 in the intervention and 34 in the control group).
