About me

I have a background of medicine. I defended my PhD thesis on psychosocial factors and preterm birth in September 2017 at Karolinska Institutet. I am currently working as a postdoc of the perinatal epidemiology group at the Unit of Clinical Epidemiology, Department of Medicine, Karolinska Institutet.

I am interested in combining the social and clinical perspectives to investigate the maternal and infant health risk or protective factors on the individual, family and social structural levels. I have worked extensively with birth cohorts established from national registers for my PhD thesis.

    To investigate the effects of maternal and paternal depression on the risk for preterm birth.


    National cohort study.


    Medical Birth Register of Sweden, 2007–2012.


    A total of 366 499 singleton births with linked information for parents’ filled drug prescriptions and hospital care.


    Prenatal depression was defined as having filled a prescription for an antidepressant drug or having been in outpatient or inpatient hospital care with a diagnosis of depression from 12 months before conception until 24 weeks after conception. An indication of depression after 12 months with no depression was defined as ‘new depression’, whereas all other cases were defined as ‘recurrent depression’.

    Main outcome measures

    Odds ratios (ORs) for very preterm (22–31 weeks of gestation) and moderately preterm (32–36 weeks of gestation) births were estimated using multinomial logistic regression models.


    After adjustment for maternal depression and sociodemographic covariates, new paternal prenatal depression was associated with very preterm birth [adjusted OR (aOR) 1.38, 95% confidence interval (95% CI) 1.04–1.83], whereas recurrent paternal depression was not associated with an increased risk of preterm birth. Both new and recurrent maternal prenatal depression were associated with an increased risk of moderately preterm birth (aOR 1.34, 95% CI 1.22–1.46, and aOR 1.42, 95% CI 1.32–1.53, respectively).


    New paternal and maternal prenatal depression are potential risk factors for preterm birth. Mental health problems in both parents should be addressed for the prevention of preterm birth.
