Description of intervention(s) / exposure
Participants will participate in two data collection sessions conducted in their homes. Variables including demographic information, symptoms of postnatal depression, health related quality of life, emotional resilience, maternal social support, physical activity self-efficacy, social support for physical activity participation, ratio of perceived advantages and disadvantages of physical activity (decisional balance) will be collected by paper based measures. Biological markers of stress (including salivary cortisol and a-Amylase) and potential genetic markers of vulnerability to depression (serotonin transporter gene polymorphisms and reelin gene (RELN) polymorphisms) will be collected by a saliva and cheek cell sample respectively. Physical activity will be measured using an ActiGraph wGT3X-BT accelerometer worn by the participant for 7 days. All of these measures (excluding the genetic sample and demographic information) will be assessed at two time points; approximately 20 weeks gestation and three months postnatal. Participants will also be asked to allow researchers access to information relating to their labor and postnatal care using methods consistent with the NSW Midwives Data Collection Form.

Outcomes
Primary outcome [1] 293387 0
Potential genetic markers of vulnerability to depression (serotonin transporter gene polymorphisms and reelin gene (RELN) polymorphisms). The serotonin transporter gene polymorphisms and reelin gene (RELN) polymorphisms will be collected via a cheek cell sample. Participants will be asked to swirl a sample of commercial mouthwash in their mouths and return the mouthwash to the specimen jar.
Timepoint [1] 293387 0
This specimen will be collected during the participants first data collection visit.

Edinburgh Postnatal Depression Scale (Cox 1987).
Timepoint [2] 293388 0
The Edinburgh Postnatal Depression Scale will be administered at two time points- prior to giving birth at approximately 20 weeks gestation and 3 months post-partum.

Secondary outcome [7] 310916 0
Objectively measured physical activity using the ActiGraph wGT3X-BT. The monitor will be worn for 7 days at each time point comprising 5 weekdays and 2 weekend days. Outcome data includes counts per minutes and time spent in moderate to vigorous physical activity.
Timepoint [7] 310916 0
As close to 20 weeks gestation as possible and three months postnatal.
Secondary outcome [8] 310917 0
Demographic information including marital status; ethnicity; education; employment status; number of children and previous pregnancies; and history of mental illness will be collected by a questionnaire designed by research staff designed specifically for the study.

Statistical methods / analysis
Relationships between measured variables at each time point will be assessed using standard statistical techniques (e.g. Pearson correlation, Fishers Z score). Multiple regression analyses will be used to determine psychosocial and biological antenatal predictors (absolute and relative changes from pre to postnatal) of postnatal physical activity and symptoms of depression.

The sample number for this study was determined based on the sample available to researchers in the time frame applicable to the study. No clinical or statistical assumptions were used to determine the sample.
