During effects pregnancy stress-Effects of prenatal stress on pregnancy and human development: mechanisms and pathways

Stress experienced by a woman during pregnancy may affect her unborn baby as early as 17 weeks after conception, with potentially harmful effects on brain and development, according to new research. The findings, published in the journal Clinical Endocrinology, come after separate research on animals showed that high levels of stress in a mother during pregnancy could affect brain function and behaviour in her offspring, and other evidence suggesting that maternal stress in humans can affect the developing child, including lowering its IQ. However, the way this happens and the implications for the unborn child, both before and after birth, are still not fully understood and further research is needed, the latest study's authors said. They said they did not wish to "unduly worry pregnant women", but highlighted the need to lead a "healthy, balanced lifestyle" to avoid general stress. The baby charity Tommy's called on family, friends and employers of pregnant women to provide support and reassurance to help them reduce stress.

Your body, your emotions and the life of your family are changing. You may welcome these changes, but they can add new stresses to your life. Feeling stressed is common during pregnancy. But too much stress can make you uncomfortable. Stress can make you have trouble sleeping, have headaches, lose your appetite or overeat. Babies born too soon or too small are at increased risk for health problems.

The causes of stress are different for every woman, but here are some common causes during pregnancy:. Stress is not all bad. When you handle it right, a little stress can help you take on new challenges. However, serious types of stress during pregnancy may increase your chances of certain problems, like premature birth. But be careful if you experience serious kinds of stress, like:. Post-traumatic stress disorder PTSD is when you have problems after seeing or experiencing a terrible event, such as rape, abuse, a natural disaster, a terrorist attack or the death of a loved one.

People with PTSD may have:. As many as 8 in women 8 percent may have PTSD during pregnancy. Doing these things can increase the chances of having pregnancy problems. If you think you may have PTSD, talk to your provider or a mental health professional. But certain stress-related hormones may play a role in causing certain pregnancy complications.

Serious or long-lasting stress may affect your immune system, which protects you from infection. This can increase the chances of getting an infection of the uterus. This type of infection can cause premature birth. Stress also may affect how you respond to certain situations. Some women deal with stress by smoking cigarettes, drinking alcohol or taking street drugs, which can lead to pregnancy problems. Some studies show that high levels of stress in pregnancy may cause certain problems during childhood, like having trouble paying attention or being afraid.

A growing body of research shows that prenatal stress can have significant effects on pregnancy, maternal health and human development across the lifespan. These effects may occur directly through the influence of prenatal stress-related physiological changes on the developing fetus, or indirectly through the effects of prenatal stress on maternal health and pregnancy outcome which, in turn, affect infant health and development.

Animal and human studies suggest that activation of the maternal stress response and resulting changes in endocrine and inflammatory activity play a role in the aetiology of these effects.

Ongoing research is focusing on clarifying these mechanisms, understanding the role of racial and cultural factors in these effects, and examining the epigenetic and transgenerational influences of prenatal stress.

It is clear that that psychosocial, cultural and environmental stressors experienced during gestation can be detrimental to pregnancy and maternal and fetal health, and recent studies suggest that prenatal stress can have consequences that span generations.

Prenatal stress can range from severe e. The concept of a psychosocial stressor encompasses changes in, for example, personal life, job status, housing, domestic violence and family makeup which require adaptive coping behaviour on the part of the affected individual. There is accumulating evidence from human and animal studies that exposure to prenatal stress can affect the health, development and long-term functioning of offspring via both direct and indirect pathways Figure 1.

Prenatal stress can indirectly affect infant health and development by increasing the risk of the occurrence of adverse birth outcomes which are, in turn, associated with substantial developmental and health consequences.

Prenatal stress can also have direct effects on infant health by altering the course of fetal neurobiological development. Studies suggest, for example, that exposure to glucocorticoids in utero either through maternal stress or exogenous administration, can affect the development of the stress response in the fetus, which can have long lasting effects on behaviour and physiology.

This review focuses on psychoneuroimmunology-oriented studies of the effects of prenatal stress on human pregnancy, infant development and the development of offspring across the lifespan.

Starting with an introduction to the effects of prenatal stress on maternal physiology and health, evidence for both direct and indirect effects of gestational on pregnancy and development is presented in the context of animal and human studies seeking to characterize the mechanisms of these effects.

Schematic of the direct and indirect pathways through which prenatal stress may affect the health and development of human offspring. During pregnancy the maternal endocrine, nervous and immune systems adjust to support pregnancy success Figure 2 , and it has been suggested that prenatal stress affects pregnancy by disrupting these processes. Among the physiological changes that occur in pregnant women are a tendency toward reduced stress responsiveness of the hypothalamo-pituitary-adrenal HPA axis and a shift in the immune system to favour an anti-inflammatory profile.

Activation of HPA and inflammatory responses during pregnancy can affect maternal health during and beyond pregnancy.

Schematic of how maternal immune and endocrine adjustments can support healthy pregnancy. Antenatal mood disorders are common and are associated with adverse pregnancy outcomes, although the relationship between stress and prenatal maternal mood is still under investigation.

Prenatal stress can indirectly affect infant development and health by increasing the occurrence of adverse pregnancy outcomes which are themselves predictive of substantial and ongoing challenges for affected offspring Figure 3.

Severe stress appears to have its greatest impact on birth outcome when it occurs early in pregnancy. For example, Carmichael and Shaw 23 noted that major stress around conception e. Similarly, death of a loved one or a terrorist attack increased the incidence of adverse outcomes including pregnancy loss when experienced early in pregnancy. For example, pregnancy-specific distress and anxiety increase the risk for PTB and shortened gestational age at birth.

Those infants who survive the perinatal period are at greater risk for physical and developmental delays in later years. Studies suggest that prenatal stress increases the risk of adverse pregnancy outcomes by disrupting adaptations in the maternal immune, endocrine and nervous systems that support healthy pregnancy. Stress and anxiety-related elevations in CRH and cortisol early in pregnancy are associated with increased risk of PTB. Women who encounter psychosocial stress during pregnancy have higher levels of CRH and cortisol than non-stressed pregnant women 36 and women who deliver preterm have significantly higher levels of plasma cortisol and CRH prior to onset of labour than women who deliver normally.

A growing body of work shows that prenatal stress can have persistent effects on behavioural, physiological and immunological functioning throughout the lifespan and may even be evident across generations Figure 4.

Animal studies show that the adult offspring of stressed rat dams exhibit impaired reproductive and grooming behaviour, demonstrating lasting neurobehavioural effects of maternal prenatal stress.

Summary of lifespan effects on human health and development associated with prenatal stress. Specifically, gestational stress experiences are associated with increased occurrence of allergy and asthma in childhood as well as reduced response to infection and lowered immunity at birth.

Exposure to stress hormones in the prenatal environment can also have lasting effects on the function of the immune system, illustrating the co-regulation of the endocrine and immune systems Figure 2. Evidence for this is provided by studies showing that prenatal administration of dexamethasone reduces cell numbers in the thymus and spleen, altering early immune function. Such exposures also alter the developing HPA axis in a manner which predisposes rats to being stress hyper-responsive later in life.

An ongoing challenge for researchers is understanding the role of racial and cultural stress in augmenting the effects of the types of prenatal stress described above in minority women. Increasing data suggest that racial stress is a contributor to the persistently higher rates of LBW, infant mortality and small for gestational age infants observed in African American women compared with white women.

Clearly, additional work is needed to tease apart these complex relationships in a manner which can inform interventional research and clinical care. Ongoing research is not only continuing to probe the mechanisms of how prenatal stress affects pregnancy outcome and offspring development, but also the extent and duration of its effects. For example, animal studies show that alterations in glucocorticoid receptor function and sensitivity can be observed not only in the immediate offspring of experimentally-stressed rats, but also in the subsequent generation, even in the absence of direct maternal stress.

Specifically, human studies indicate that second-generation offspring of women who experience stress during pregnancy may have alterations in glucocorticoid signalling and increased susceptibility to affective disorders. Additional longitudinal studies are required to fully characterize the extent and significance of these epigenetic effects of prenatal stress, and at this time, few studies have concurrently and longitudinally assessed the necessary biological, psychological and lifespan variables necessary to accomplish this.

Within this context, others are focusing on developing effective and efficient clinical interventions to reduce the effects of prenatal stress on maternal health and fetal development. National Center for Biotechnology Information , U. Journal List Obstet Med v.
