Summary

  • In the postpartum period, 7.5% of women reported depressive symptoms.
  • Before they became pregnant, 15.5% of women were either diagnosed with depression or treated with anti-depressants.
  • In the 12 months before childbirth, 12.5% of women reported that most days were very stressful.
  • Some women (13%) had little or no support available to them during their pregnancy.
  • Women who experienced physical or sexual abuse were more likely to report postpartum depressive symptoms, a history of depression, stress, and little or no social support.

Introduction

For most women, pregnancy and birth are a time for celebration. However, this can also be a time of change in a woman’s body and lifestyle, which may increase the risk of poor mental health.

The World Health Organization defines mental health as a “state of well-being in which an individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community.”Footnote 1

It is important to assess pregnant women’s mental health because it can affect not only the woman’s health, but also her newborn’s health and development. This fact sheet presents information on four selected indicators of women’s mental health covered in the Canadian Maternity Experiences Survey (MES): postpartum depression, history of depression, stress, and social support.

Four risk factors that are linked to the mental health indicators described above include: smoking, the use of alcohol and non-prescription drugs, and women’s history of physical or sexual abuse.

Postpartum depression

Overall, 7.5% of women reported depressive symptoms during the postpartum period. Women with depressive symptoms were also more likely to smoke, consume alcohol, use non-prescription drugs, and experience physical or sexual abuse than women without these symptoms (Figure 1). For example, although few women reported using non-prescription drugs during pregnancy, four times as many women with depressive symptoms reported this, compared with women without these symptoms (3.7% compared with 0.8%).

Risk factor Depressive Symptoms No Depressive Symptoms
Smoking (daily/occasionally during last 3 months of pregnancy) 15.4% 10.2%
Alcohol Use (any drinking during pregnancy) 11.9% 10.5%
Drug Use (used drugs during pregnancy) 3.7% 0.8%
Physical or Sexual Abuse (in the last 2 years) 23.2% 10.0%

History of depression

In the MES, a history of depression was defined as women who have been diagnosed with depression or prescribed anti-depressants before they became pregnant. Before pregnancy, 15.5% of women overall were either diagnosed with depression or treated with anti-depressants. These women were more likely to smoke, consume alcohol, use non-prescription drugs, and experience physical or sexual abuse than women who had no history of depression or had not been prescribed anti-depressants (Figure 2). For instance, they reported smoking during the last three months of pregnancy almost two times (18.1%) as much as other women (9.1%).

Smoking (daily/occasionally during last 3 months of pregnancy) 18.1% 9.1%
Alcohol Use (any drinking during pregnancy) 12.7% 10.1%
Drug Use (used drugs during pregnancy) 2.3% 0.7%
Physical or Sexual Abuse (in the last 2 years) 18.4% 9.7%

Self-reported stress

The MES asked women about their levels of stress in the 12 months before their baby was born. Women who reported high levels of stress were more likely to smoke, use non-prescription drugs, and experience physical or sexual abuse than women who reported some or no stress (Figure 3). Overall, 12.5% of women reported that most days were very stressful. Women who reported that most days were very stressful had higher proportion of physical or sexual abuse in the previous two years, with over three times (20.7%) that of women with no stress (6.6%).

Drug Use (used drugs during pregnancy) 2.2% 0.9% 0.7%
Physical or Sexual Abuse (in the last 2 years) 20.7% 12.4% 6.6%

Social support

Overall, 13% of women had little or no support available to them during their pregnancy. Such women were more likely to smoke, consume alcohol, and experience physical or sexual abuse than women with social support (Figure 4). When asked about the past two years, 16.3% of women with little or no social support reported physical or sexual abuse compared with 10.2% of women with social support.

In 2006–2007, the Canadian Maternity Experiences Survey (MES) surveyed Canadian women about their experiences and practices before and during pregnancy, after childbirth, and in the early months of being a parent. The MES was a project of the Canadian Perinatal Surveillance System (CPSS) which monitors and reports on key indicators of maternal, fetal and infant health in Canada.
