Conceptual Framework of Risk Factors of Preterm Birth
Preterm birth (PTB) is defined by World Health Organization (WHO), as “a premature birth occurs before the start of the 37th week of pregnancy”(World Health Organization). It is not only a medical problem but also a huge public health issue, because the consequences of preterm birth include multiple infant health problems, such as multi-organ dysfunction and developmental defects, later behavioral and psychological disorders, and higher infant mortality rates. For example, a study indicates that preterm births accounts for one third of infant mortality in the US (Callaghan et al.). Considering the severity, the health outcome is PTB in this conceptual framework.
In St. Louis, the prevalence of PTB is 12.5%, higher than both Missouri and National level respectively (9.8% vs. 9.6%) (National Center for Health Statistics (US) Division of Vital Statistics). Moreover, in St. Louis where 49.2% residents are African Americans (AAs), the prevalence of PTB among AAs are higher than European Americans (13.4% vs. 9.1%), suggesting health disparity is prominent. In addition, AA female adolescents are vulnerable to teen birth due to 26% of teen births and 22% repeat teen pregnancy are AAs (U.S. Department of Health & Human Services, Office of Adolescent Health). Thus, the target population in current conceptual framework is AA teenage mothers (age under 20 years).
The risk factors of PTB in current framework are classified into four
According to the World Health Organization (WHO, 2016), preterm birth are the birth that happened before 37 ended weeks of pregnancy and is one of the number reason of newborn deaths and the second prominent cause of deaths in children below five. The preterm babies have chances of an amplified risk of illness, disability and death. In the first weeks, the complications of premature birth may include: breathing problems, heart problems, brain problems, temperature control problems, gastrointestinal problems, blood problems, metabolism problems, immune system problems. Long-term complications includes cerebral palsy, impaired cognitive skills, vision problem, hearing problems, dental problems, behavioral and psychological problems, chronic health issues.
Defining premature birth is much more than just a denotative phrase. It is not just a preterm birth, or a baby born early. It is a life-changing event, and something that affects millions of people worldwide. The intense quiet room with heart monitors beeping, as parents see their baby and are devastated. Loved ones can not feed them or kiss them nor, can they not hold them or hug them. They do not get the same experience as others. Little miracles lay inside these cubes where multiple wires are help keeping them alive. A place where prayers happen, and where all hope for the best. Nobody knows the true pain and struggle behind a preterm birth and it needs to be discussed. Prematurity is a serious conflict; therefore, it needs more awareness as many families are facing this tough situation.
Premature birth is an important public health priority in terms of health of women and infants. Every year an estimated 15 million preterm babies are born and this number is still rising (WHO, 2015).In 2014, 1 of every 10 babies born in United States were premature and black infants were 50% more likely to be born premature than white, Hispanic and Asian/Pacific islander infants (CDC,2015). Almost 1 million children die each year due to complications of premature birth (WHO, 2015). Major survivors face lifelong disabilities like learning disabilities, hearing, visual, feeding, digestive, breathing and respiratory problems (CDC, 2015) and low birth weight (March of Dimes, 2014). A major challenge in decreasing the rate of preterm birth is
Infant deaths in the neonatal period are caused by complications arising from preterm births, birth defects, maternal health conditions, complications of labor and delivery, and lack of access to appropriate care at the time of delivery. Infant deaths in the post-neonatal period are driven by sudden unexpected infant death (SUID) (including sudden infant death syndrome [SIDS]), injury, and infection (MMRW, 2013). An increasing proportion of post-neonatal infant deaths occur among infants who were born preterm but survived the neonatal period (Callaghan, 2006). On the other hand there is lesser knowledge of the incidence and etilogy of fetal mortality which according to MacDorman et al, makes fetal mortality an overlooked public health issue. Lee et al, echoed the same idea when they said infant mortality has been the main focus of public health programming while fetal deaths have gone untargeted. However, with the decrease in infant mortality rates there have been recent approaches such as perinatal period of risk analysis framework (PPOR) that highlight the need to include fetal
Multiple studies have been conducted on infant mortality and preterm birth in the United States. Many have identified how the rate of infant mortality and preterm birth is twice as high among African Americans women than White American women in the United States.(Orr et. al,2012; Dole et al,2004;Collins,2002) some studies convey socioeconomic as a major factor of preterm birth among African American’s. As Kleinman conveys in Racial differences in low birthweight: Trendsand risk factors when socioeconomic status increases the risk of giving birth to an infant of low birthweight decreases. On the other hand, there are some studies that convey high differences of preterm birth between black and white women of equal socioeconomic status.(Dole et
Premature birth has been linked to a vast array of lungs problems, the earlier the birth the greater risk of health complications(Davis R and Mychaliska G, 2013). A majority of the health problems will affect the infant for the rest of their life (Davis R and Mychaliska G, 2013). Infants born between the canalicular and the saccular period (week 25) have lung development that is unsuitable for gas exchange (Davis R and Mychaliska G, 2013). Two major complications that arise with undeveloped lungs is bronchopulmonary dysplasia, and pulmonary arterial hypertension (Mahgoub L. et al. 2017).
-Race or ethnicity: Historically, minority populations in the United States have had higher rates of preterm delivery. In 2007, non-Hispanic White women accounted for the lowest number of preterm births in the United States, accounting for only 11.5% of all preterm births (MacDorman, 2011). In contrast, non-Hispanic Blacks, Puerto Ricans, American Indians and Hispanic women had preterm birth levels of 18.3%, 14.5%, 13.9% and 12.3% respectively (MacDorman, 2011). The Asian minority had the lowest risk at 10.9% (MacDorman, 2011). Some studies have attributed such significant differences to racial disparities in resources and health care (Dominguez, 2008; Vanderbilt & Wright, 2013). However, other studies such as Menon’s et al, which looked at differences in White versus Black women, suggest that racial disparities in preterm birth may
The patient population is the preterm babies that are less than 37 weeks’ and weight
Early prenatal care is essential to mothers and babies. Doctors preferably see their pregnant patients around 8 weeks of pregnancy in which an initial evaluation is conducted which includes checking for sexually transmitted infections, they screen for gestational diabetes, and to find out when the due date is. When a woman comes in during the third trimester for an initial check-up, the due date is typically not accurate; which could result in preterm labour. Being born preterm has severe consequences, such babies are more at risk for respiratory distress syndrome, and later on in life diabetes, heart disease and obesity. Among the benefits of prenatal care is the ability to anticipate future or current problems; hence, it is essential to the health of both mother and child. Prenatal care allows health care providers to take timely measures to ensure the wellbeing of the mother and
After revising the key terms, additional searches were made using both CINAHL and MEDLINE databases, with each article being evaluated and better search mechanisms being applied. In this search the key words preterm AND aboriginal women were used with the result being relatively successful, however there were still a number of articles that were not all applicable. I then decided to go through each article and critique how each study was conducted and what information it could provide to increase my knowledge on the factors that affect preterm birth. Additionally I also looked at which articles provided the highest level of evidence using NHMRC guidelines, as well as observing the number of people who had cited the source (National Health and Medical Research Council, 2015). Being more specific in database searches was a skill that became vital in the search process (Symmons, 2013). For example, I also chose synonyms such as, ‘neonatal outcomes’ and ‘premature pregnancy’ so articles relevant to preterm birth could be discovered. By establishing effective search terms, evaluating the reliability of the source, restricting
This positive trend is evidence that some of the outreach efforts to which we've committed ourselves as a public health community are working. However, these improvements should not undermine the still considerable task before this same community. Specifically, we have a responsibility to hone our efforts at identifying, understanding and reaching the populations that are most vulnerable as well as helping to reduce the adverse consequences that accompany this vulnerability. The purpose of the present epidemiology is to further the collective understanding of teen pregnancy as a current public health issue.
Premature birth is a public health crisis because it is responsible for 75 percent of infant
Preterm birth can be a devastating experience not only for the mother, but also for the child. This issue has plagued the United States and other countries for many years, and no concrete evidence have been found to tell us why preterm birth occurs. One in eight babies in the United States is born premature each year. The impact of social support on the psychological well-being, attitudes, and behavior of parents is rapidly becoming a major issue. It is becoming more and more difficult for mothers to cope with the long-term and short-term effects of premature birth. These parents’ attitude and behavior can have both a direct and indirect effect on the child's
Pregnancy is normally the best and the happiest stage of any woman, but it can also be uncertain because anything can go wrong if you do not know exactly what to do. In order to understand the reasons of why Preterm Birth occurs, it is important to know what it is and how risky it can be. Preterm Birth is also known as Premature labor which mainly begins after “20 weeks but before 37 completed week’s gestations. Approximately 12.9 million babies worldwide are born too early every year representing an incidence of PTB of 9.6%” (Berghella, pp. 2, 8). Baby Center Medical Advisory Board says that about 12 percent of babies
While some women who received no prenatal care had normal, uncomplicated births, others did not. Most of the women who did not receive adequate prenatal care gave birth to an underweight and underdeveloped infant. Among the benefits of early, comprehensive prenatal care are decreased risk of preterm deliveries and low birth weight (LBW)-both major predictors of infant morbidity and mortality. (Dixon, Cobb, Clarke, 2000). Preterm deliveries, deliveries prior to 37 weeks of gestation, have risen. Since the studies in 1987, which showed the rate of preterm deliveries as 6.9% of births, the 1997 rate shows an increase to 7.5%. Low birth weight, defined as an infant weighing less than 2500 grams (5lbs. 5oz) is often preceded by preterm delivery. Low
