Developing a Better Understanding of How Natural Disasters Can Affect Pregnancy
Natural disasters such as hurricanes, floods, earthquakes and tsunami’s affect millions of people each year. Lives are lost, loved ones are separated or missing and psychological trauma is inevitable. Now imagine that you are pregnant and the magnitude of the situation becomes even greater. This is exactly what happened to Jill. Jill was 32 weeks pregnant, with her first child, when Hurricane Katrina struck. Jill was a college professor at a university in New Orleans. She was forced to relocate because her house was located in a flood zone. She and her husband drove for over 2 days to get to New Hampshire so that they could stay with her parents. Her parents live in a 1 bedroom house so Jill and her husband were staying in the basement. Once the storm had cleared, it was evident that their home and all their belongings were destroyed. The city she had once called home was devastated. She is now homeless, jobless and expecting her first child in 8 short weeks. Because Jill’s mother is well connected in the community, Jill was able to get into see a midwife and establish prenatal care in the area. Jill’s only other risk factor, during this pregnancy, has been with depression. Jill is not the only pregnant woman who has been displaced by a natural disaster, therefore, this paper will explore the affects of natural disasters on pregnancy and if post traumatic stress disorder is real concern for these women.
Hurricane Katrina occurred just after Labor Day in September 2005. The expanse of this natural disaster reached over multiple states; devastating homes, communities and entire cities. This particular disaster displaced over hundreds of thousands of people. Survivors of the hurricane spent long hours, in over crowded shelters, that weren’t adequately set up to handle amount of people within them. Others were forced to their rooftops until they could be rescued. And still others found themselves on a deserted patch of highway (Voelker, 2005). The American Psychiatric Association and The American Red Cross sent mental health professionals to the shelters in order to provide professional services to the survivors. Most of the work was crisis intervention. Long term work to help these victims will need to be ongoing because mental health repercussions for thousands of overwhelmed survivors likely had not yet surfaced (Voelker, 2005).
The immediate aftermath of a natural disaster can leave people scrambling around for food, shelter, safety, and water. This can pose a real threat for pregnant women and newborns in particular. Finding drinking water and food that is not contaminated can be difficult or near impossible. The survivors will need to be educated on how to decontaminate the food and water prior to consuming it. If the water is contaminated it may contain bacteria that could cause a serious intestinal disease (March of Dimes, 2005).
It will also be important to avoid the areas affected by the hurricane. The mere act of walking in the contaminated water can expose the pregnancy to toxic waste or bacterial infections. If a pregnant woman is exposed to a toxic substance, and is concerned, there is a hotline number posted for them to call on the March of Dimes website. It is imperative that rescue workers are knowledgeable about the resources available to help protect the women and children in events of natural disasters.
For most women, pregnancy is a time for hope, excitement, and exploration. Pregnancy also signals change. Change to one’s body, lifestyle and family. These changes often add stress to ones life. However, stress is not always bad. Stress, when managed properly, “can provide us with the drive to meet new challenges” (March of Dimes, 2005). Pregnancy is also a time when concern is heightened, as a natural instinct, to protect their unborn child. If a threat, such as a natural disaster, is added to their situation then feelings of stress can build. Natural disasters can evoke feeling of fear, anxiety, guilt, depression, shock, anger, helplessness, hopelessness and emotional numbness (Young, Ford, & Watson, 2005). However, increased stress in pregnancy can potentially cause some serious health problems such as: lowered resistance to infectious diseases, high blood pressure, and heart disease. “Studies also suggest that high levels of stress may pose special risks during pregnancy, such as, preterm labor and low birth weight” (March of Dimes, 2005). However, it is important to understand that people react differently to different situations.
The most common symptom of a traumatic event is anxiety (Foa, Hembree, Riggs, Rauch, & Franklin, 2005). People who have been exposed to natural disasters often see the world as filled with danger, causing their bodies to constantly be on alert. This feeling often becomes uncomfortable if it occurs over a long period of time (2005). These emotions and symptoms, if left untreated, are precursors for a condition referred to as Post Traumatic Stress Disorder (PTSD). Post traumatic stress disorder, according to the DSM IV is defined as a,
psychiatric disorder characterized by a wide range of symptoms that have developed in
response to a significant and overwhelming stressful incident or from chronic exposure to intolerable stressful conditions. The individual experiences the stressful incident or
incidents as a life-or-death threat to his or her safety and personal integrity. He or she
often witnessed death or extremely horrendous conditions in which the life or integrity of
others is threatened or actually occurs (Mahan, 2004, pg 1245)
PTSD can be difficult to recognize and treat because everyone experiences life differently. However, there are common factors that can influence the development of PTSD. The first factor to consider is the persons’ developmental level at the time of exposure to the traumatic event (2004). Children do not typically have the life experiences necessary to buffer the traumatic event and put it into perspective. Therefore understanding where the person was developmentally during the trauma will go a long way in helping to diagnose and treat PTSD.
The second factor to look at is what the person’s length of exposure was. The literature shows people are less likely to develop long term effects after a short exposure to a traumatic event versus a long term persistent exposure (such as ongoing abuse) (Mahan, 2004). The next factor to examine is the person’s temperament and personality. A person’s personality and temperament can either buffer the experience or potentiate it (2004). In addition to considering a person’s personality is to consider their family history of psychiatric illness. A family history of psychiatric illness can predispose a person toward developing PTSD (2004).
Other additional factors that may influence how a person reacts to a traumatic event is the person’s proximity to the event, the severity of the experience, the nature of the traumatic situation and the availability of help immediately following the tragedy. It has been shown that early intervention can help minimize the development or the severity of PTSD (Mahan, 2004). It is also important to remember that not everyone exposed to a traumatic event will develop PTSD. Some people are more vulnerable to stress while other people are more resilient to different stressors (2004).
The clinical presentation for people suffering from PTSD fall into three different types: re-living the experience, avoidance of the situation and being in a state of increased arousal (CDC, 2005). The first symptoms of reliving include,
flashbacks, nightmares, and extreme emotional and physical reactions of the event.
Emotional reactions can include feeling guilty, extreme fear of harm, and numbing of
emotions. Physical reactions can include uncontrollable shaking, chills or hear
palpitations, and tension headaches (CDC, 2005).
The second types of symptoms include avoidance of situation. These include: “staying away from activities, places, thoughts or feeling related to the trauma or feeling detached or estranged from others” (CDC, 2005). The final groupings of symptoms include those of increased arousal. This can be characterized as, “being overly alert or easily startled, difficulty sleeping, irritability or outbursts of anger, and lack of concentration” (2005). In addition to the above listed symptoms, other symptoms that have been linked to PTSD include, “panic attacks, depression, suicidal thought and feelings, drug abuse, feeling of being estranged and isolated, and not being able to complete daily tasks” (2005).
Common strategies used to reduce normal stress in pregnancy should be reinforced after an exposure to traumatic event. Such strategies include: eating properly, getting proper rest, and exercising regularly. If these strategies do no prove to be effective, then additional measures will need to be taken. Any person showing signs of PTSD should be referred to a therapist for psychotherapy. If therapy is not working then pharmacologic interventions may be necessary to treat the underlying condition be it anxiety or depression. Also close monitoring for suicidal ideation is imperative. Ideally, recognition of the problem will be the key to finding the right treatment options for the individual. Careful surveillance by the health care provider, after a natural disaster, can go a long way to minimizing the long term consequences to the woman and her family. Due to the significance of these natural disasters and their affects on pregnancy, a variety of studies have been done to look at what a role natural disasters play during pregnancy. A few of these studies have been summarized below in an attempt to develop a clearer understanding of what role natural disasters can play during pregnancy.
One study looked at the morbidity and pregnancy outcome of those women involved in the Taiwan 921 earthquake (Chang, Chang, Lin, & Kuo, 2002). What they found was that increased stresses may be associated with higher rates of psychiatric morbidity (2002). The research also revealed that PTSD symptoms were more prevalent in women, preschool children and elderly over 65 who were exposed to extreme stresses (2002). The most significant pregnancy related morbidity was found to be an increase in low birth weight infants. They attributed the low birth weight to “maternal history of abdominal injury, spouse casualty and instability in living conditions” (Chang, Chang, Lin, & Kuo, 2002, p. 143).
Another study by C. Loveland Cook et al. examined PTSD in pregnancy paying closer attention to women in the lower socioeconomic environment. What their study revealed was that posttraumatic stress disorders “significantly increased the probability of alcohol abuse and dependence. Neuroendocrine changes associated with chronic stress influence maternal-fetal health, including maternal vulnerability to hypertension and increased susceptibility to infection (Loveland Cook et al. 2004, p. 715). The study also revealed that women with PTSD had more pregnancy related complications such as: ectopic pregnancies, miscarriages, hyperemesis, and preterm contractions. In addition, they also found that the “underlying mechanisms of how this disorder affects these outcomes are unknown” (Loveland Cook et al. 2004, p. 715). The study also stresses the importance of screening for risk factors of PTSD during pregnancy. “Identification of risk factors in this study demonstrate that women with posttraumatic stress disorder were 5 times more likely to have a major depressive episode, 3 times more likely to have generalized anxiety disorder, and more then 6 times more likely to have a history of multiple traumatic events (Loveland Cook et al. 2004, p. 716). Some of the approaches used to help these women, according to the research, included: offering supportive counseling, teaching stress reduction techniques, initiating support groups, supporting continuity of care with the same provider, scheduling more frequent visits, and initiating telephone calls between visits (2004). Another study by Holly Kennedy and Emily MacDonald recognized the importance of developing a birth plan for women suffering from PTSD (2002). They found that a birth plan would place some control back to the woman during labor (2002).
Another big decision to make following a natural disaster is whether or not to relocate after the event. In the case of Hurricane Katrina, most survivors were not given the option of returning to their home and relocation was their only alternative. One research study looked at the affects of relocating after a natural disaster. What they found was that “relocating did not diminish the prevalence of PTSD in the adults who witnessed the earthquake and were displaced” (Najarian et al., 2001, p. 521).
The findings suggest that remaining at the site of the disaster was associated with a quicker recovery and healing (2001). They go to report that, “relocated adults are at particularly high risk for depression in addition to PTSD and a variety of other psychiatric symptoms” (Najarian et al., 2001). The study results suggest providing direct aid to the victims, maintain them in their natural environment and expedite the reconstruction process (2001).
The findings from the above listed studies illustrate the need for hypervigilance by the heath care professionals caring for pregnant women who have been exposed to a natural disaster. Jill is a prime example of someone who is at high risk for developing PTSD. She’s 32 weeks pregnant, has been recently exposed to a natural disaster, has been relocated to a new state, lost her friends, home and job and has a history of depression. It will be important for Jill to have increased surveillance during the remainder of her pregnancy. Furthermore, it will be wise to help her get connected with the community through support groups and pregnancy classes. She should also be assisted in looking for a therapist in the area. A close relationship between the healthcare providers can better help to maintain continuity during the remainder of her pregnancy and after her pregnancy. Finally, it is important that healthcare providers be aware of the resources available to assist these women and their families. The American College of Nurse Midwives has put together some resources for clinicians which is entitled, “Resources for Providing Care for Woman and Infants in Disasters and Low-Resource Settings” (Keeney, 2004). Understanding the implications of natural disasters and its affects on pregnancy can go a long way in minimizing the trauma and possible consequences to the women and their families.
