This study is designed to test whether an alternative medicine treatment, fish oil, will prevent depressive symptoms in pregnant and postpartum women who have been found to be at risk for depression. Epidemiologists have observed that people who live in countries where people on average eat a diet high in fish have a lower risk of depression than people who live in populations that eat less fish. Postpartum depression is also less common in these countries. The omega-3 fatty acids found in fish oil are thought to be responsible for this beneficial effect of eating fish. The two major omega-3 fatty acids found in fish are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). DHA is an essential building block of the brain and nerve tissue. EPA may act to optimize the electrical signals between nerve cells and brain cells and may help the immune system to function well.
Some researchers have treated people who are already suffering from depression with fish oil. Some of these studies have shown a benefit for the fish oil treatment and others have not. These studies have tested EPA and DHA alone and in various combinations. Currently, it is not known whether EPA or DHA is more effective in preventing and treating depression. Some of the researchers involved in this study have learned how to identify mothers who are most at risk for developing depression during and after pregnancy. This study is designed to learn whether EPA-rich and DHA-rich fish oil supplements will prevent depressive symptoms in women who are at risk to develop depression.

- Beck Depression Inventory [ Time Frame: 6 - 8 weeks postpartum ]The Beck Depression inventory scores depression based on 21 items, with a score of 0 - 3 on each item where 0 is no depression and a score of 31 or more is clinically depressed. The 21 items were summed to obtain the total score (The maximum possible score is 63.)
- Maternal Outcomes [ Time Frame: visits at 26 - 28 weeks gestational age, 34-36 weeks gestational age during pregnancy and at the post partum visit 6- 8 weeks after delivery ]While the maternal outcomes assess criteria during pregnancy and relating to delivery they were assessed at visits 26 - 28 weeks gestational age, 34-36 weeks gestational age and at the post partum visit 6- 8 weeks after delivery.
- Gestational Age at Delivery (Weeks) [ Time Frame: delivery date was assessed by medical record review between 1 day and 8 weeks after delivery ]
- Estimated Blood Loss (ml) [ Time Frame: Within 24 hours after delivery ]
- Neonatal Birthweight [ Time Frame: immediately after birth ]Mean weight in grams: where <2500 gm is considered small for gestational age and >4500 gm is considered large for gestational age.
- NICU (Neonatal Intensive Care Unit) Admissions [ Time Frame: 6 weeks post delivery ]Admission to the NICU
- One Minute Apgar Score [ Time Frame: 1 minute after birth ]Apgar scores are based on a scale of 0 - 10 where 0 is a dead baby and 10 is an optimally vigorous newborn. The Apgar score analyzed here is the one minute Apgar.
- Five Minute Apgar Score [ Time Frame: 5 minutes after birth ]Apgar scores are based on a scale of 0 - 10 where 0 is a dead baby and 10 is an optimally vigorous newborn. The Apgar score analyzed here is the five minute Apgar.
- Cord Arterial pH [ Time Frame: Immediately after birth (collected within the first hour after delivery) ]Arterial blood gas analysis of umbilical cord blood
