While progress has been made in reducing neonatal mortality in Guatemala, stillbirth and maternal mortality rates remain high, especially among the indigenous populations, which have among the highest adverse pregnancy-related mortality rates in Guatemala.
We conducted a prospective study in the Western Highlands of Guatemala from 2010 through 2013, enrolling women during pregnancy with follow-up through 42-days postpartum. All pregnant women were identified and enrolled by study staff in the clusters in the Chimaltenango region for which we had 4 years of data. Enrolment usually occurred during the antenatal period; women were also visited following delivery and 42-days postpartum to collect outcomes. Measures of antenatal and delivery care were also obtained.
Approximately four thousand women were enrolled annually (3,869 in 2010 to 4,570 in 2013). The stillbirth rate decreased significantly, from 22.0 per 1000 births (95% CI 16.6, 29.0) in 2010 to 16.7 (95% CI 13.5, 20.6) in 2013 (p-value 0.0223). The perinatal mortality rate decreased from 43.9 per 1,000 births (95% CI 36.0, 53.6) to 31.6 (95% CI 27.2, 36.7) (p-value 0.0003). The 28-day neonatal mortality rate decreased from 28.9 per 1000 live births (95% CI 25.2, 33.2) to 21.7 (95% CI 17.5, 26.9), p-value 0.0004. The maternal mortality rate was 134 per 100,000 in 2010 vs. 113 per 100,000 in 2013. Over the same period, hospital birth rates increased from 30.0 to 50.3%.
In a relatively short time period, significant improvements in neonatal, fetal and perinatal mortality were noted in an area of Guatemala with a history of poor pregnancy outcomes. These changes were temporally related to major increases in hospital-based delivery with skilled birth attendants, as well as improvements in the quality of delivery care, neonatal care, and prenatal care.
Each year, families in low and middle income (LMIC) countries face the death of approximately 4 million newborns, 3 million fetuses and 300,000 pregnant women (99% of those that occur worldwide) [1–4]. Millennium Development Goal 4 (MDG4), which called for a two-thirds reduction in child mortality by 2015, depended in large part on the reduction of neonatal deaths, which made up 37% of child mortality in 1990 and 42% in 2014 [1, 5]. The main causes of neonatal mortality in LMIC are preterm birth, birth asphyxia and infections; one third of deaths occur during the first 24 hours of life [3, 6–8]. There is evidence of accelerating declines in neonatal mortality from 2000 to 2010 in many LMIC; reasons for these decreases include the introduction of national policies to promote development and increased access to health care, rising income of families and improved maternal education .
Third trimester stillbirths are a relatively common adverse pregnancy outcome in LMIC that in many instances, are potentially preventable [10–12]. Up to 70% of these deaths occur in the the intra-partum period in LMIC [8, 12]. The main causes of stillbirths are asphyxia due to obstructed labor, placental abruption, preclampsia or eclampsia and umbilical cord complications . Despite their high frequency, stillbirths were not included in the MDGs or in the Countdown to 2015 and are often not considered when pregnancy outcomes are reported from LMIC [12, 13]. Because of their common causality, interventions that reduce stillbirths frequently reduce maternal and neonatal mortality .
An estimated 60 million women give birth each year outside of health facilities, mainly at home ; fifty-two million of these births occur without the assistance of a skilled birth attendant, frequently by traditional birth attendants (TBAs) or a family member . In an effort to improve pregnancy outcomes overall, the World Health Organization (WHO) recommends the use of skilled birth attendants for delivery, as TBA training for the reduction of stillbirths and neonatal deaths has not been proven to be effective . TBAs in Guatemala, known as comadronas, have a large role as providers of reproductive health services, in addition to being community leaders . Eighty five percent of TBAs in the Chimaltenango region report one month or less of formal training, 60% are illiterate and less than one fourth report using a stethoscope for heart rate auscultation .
Chimaltenango is one of 22 states in Guatemala. Located in the western highlands, it has a population of 595,000, out of which 75% of inhabitants are indigenous and 50% live in rural areas. The United Nations human development index (HDI) for the region is 0.679, slightly lower than the HDI for the country (0.702). The maternal, fetal and neonatal mortality rates in this state are substantially higher than in other states . In addition, indigenous peoples face the highest poverty rates.
We sought to explore the changes that have occurred in maternal deaths, neonatal deaths, stillbirths, and perinatal deaths between 2010 and 2013 in the Chimaltenango region of the Guatemalan Western Highlands. We also explored which characteristics and changes in these characteristics in the mothers, infants, or health services were temporally related to the decreases in mortality. This in-depth study of a particular geographic allowed us to understand the trends, and, if improvements occurred, the factors related to those improvements. The Every Newborn Action Plan, established by the World Health Assembly in 2014, calls for neonatal mortality and stillbirth rates to fall to below 10 per 1000 births by 2030 [6, 13]. The present analysis should contribute evidence for the attainment of these goals in Guatemala.
The study was conducted as part of the Global Network Maternal and Newborn Health Registry (MNHR) study, a multi-country research study. The purpose of this registry is to quantify and analyze trends in pregnancy outcomes in defined low-resource geographic areas over time in order to provide population-based statistics on pregnancy outcomes. The MNHR study enrols all pregnant women in the cluster, a defined geographic area. These analyses focus on the MNHR study clusters in the Chimaltenango region from January 1 2010 through December 31, 2013 (the last available data), in order to evaluate trends over a sufficient time period.
To be informed of pregnancies in the communities, auxiliary nurses work together with the TBAs and the Ministry of Health services. The auxiliary nurses, who are full time study staff, visit women in their homes during pregnancy, following delivery (in the hospital or in the home, depending on where delivery occurred) and at six weeks post-partum in order to collect data on the health services and basic outcomes for each woman. All pregnancies, deliveries, stillbirths and deaths are checked against the data provided by local Ministry of Health and civil registry records. These data represent between 24 to 29% of all births in the department (state) of Chimaltenango for this time period.
Pregnancies were diagnosed mainly by self-referral of the mothers, by report of the TBAs, or by Ministry of Health records. All maternal deaths, including those in the first trimester, were included in the analysis. The gestational age was determined mainly by last menstrual period (LMP), as ultrasound gestational age determination was not widely available during this time period. Preterm birth was defined by LMP, report of the birth attendant or by using low birth weight as a proxy.
Stillbirths were defined as all fetal deaths at greater than 20 weeks gestation per 1000 births (live and stillbirths). Neonatal morality was defined as all neonatal deaths <28 days per 1000 live births. Finally, perinatal mortality was defined as all fetal deaths ≥20 weeks gestation plus early <7 day neonatal deaths per 1000 births. Maternal mortality was defined as all maternal deaths per 100,000 deliveries. We defined facility births as any delivery occurring within a health facility and community births as any delivery occurring at home or a TBA’s home.
Data were entered at a secured data computer at the research site located in Chimaltenango. Data were reviewed and edited on site, prior to transmission to the central data coordinating center (RTI International, US). Further edits were performed at the central data center, which were then resolved at the Guatemala data center. Data analyses included descriptive statistical analyses, to evaluate the rates, means and standard deviations. We used generalized estimating equations to account for correlation of outcomes within clusters to assure appropriately sized p-values. To evaluate changes in outcomes over time, we modelled year of delivery as a categorical value and tested for changes between years 2010 and 2013 with a simple difference contrast and also conducted trend tests. All data were analyzed using SAS v9.3 (Cary, NC).
The study was reviewed and approved by the ethics committee of Francisco Marroquin University, Guatemala as well as by the collaborating institutions at University of Colorado-Denver, Columbia University and RTI International, the data center. All women provided informed written consent for data collection prior to their study enrolment.

We also stratified our analyses by birth weight to attempt to determine whether changes varied in neonatal mortality and stillbirth rates from 2010 to 2013 by birth weight group. The largest decrease in neonatal mortality occurred in the 1500 – 2499 gram birth weight group with mortality at 28 days decreasing 52%, from 92.4 to 44.4 deaths per 1000 live births over the 4 year period (p=0.0424 for trend). A smaller 22.5% decrease in mortality occurred in ≥ 2500 gram infants, from 17.3 to 13.4 deaths per 1000 live births (p = 0.4510). No consistent changes in neonatal mortality were observed in 1000 to 1499 gram infants (p =0.5767). Stillbirths weighing 1000-1499 grams declined from 400 to 262 per 1000 births (p=0.0591), and in the ≥2500 gram group decreased by 16%, from 45 to 37.7 deaths per 1000 births (p=0.4510).
Evidence from high income countries suggests that the most effective interventions in improving health outcomes of fetuses, newborns and mothers result from upgrades in systems of perinatal care. These have translated into better medical care provided by more and better trained physicians and other obstetric providers during the antenatal and delivery periods, availability of caesarean sections, and neonatal care (including neonatal resuscitation), and of integrated programs that focus on improving pregnancy outcomes . It has been suggested that in LMIC, child survival strategies should direct resources and focus on neonatal health . Improved levels of maternal education have also been found to have a large effect on reduction of child mortality . MDG 4 for Guatemala, which aimed for the reduction of under-five mortality by two thirds, is close to being achieved . Neonatal mortality in Guatemala in 1987 was 36 per 1,000 live births. In 2009, it had reduced to 18 per 1,000 live births . There is a dearth of data on stillbirths in Guatemala, as is the case in many other LMIC .
From 2010 to 2013 in the Chimaltenango area of Guatemala, decreases were observed in perinatal mortality, stillbirths and 28 day neonatal mortality. We explored factors that could be related to these decreases by examining changes in the characteristics of mothers, of infants and of health services over this time period. Small changes occurred in the parity and educational level of mothers over time; no other changes were observed in this group.
A large increase occurred in the proportion of births taking place in a hospital or clinic during this time period. The Guatemalan National Congress approved the National Law for a Healthy Maternity and the National Plan to Promote Maternal and Neonatal Health during 2010. Together, the law and corresponding policy change increased access to health care for women and infants during the prenatal period, delivery and pospartum period, and developed surveillance and financing mechanisms. These two laws impacted multiple governmental institutions (ministry of health, municipalities, firefighters) in Chimaltenango, who promoted hospital deliveries and provided transportation, when needed for maternal or neonatal care. We believe that even though women were not given financial incentives for delivering in the hospital, these larger contextual factors created an increase in hospital deliveries.
The overall quality of care in terms of qualified health personnel, and the availability of the components of comprehensive obstetric care improved over this time period. Obstetrics and pediatrics residency programs began early 2010 and 2011, respectively. A new obstetrical wing in the Chimaltenango Hospital opened during January of 2011, and the neonatal intensive care unit during October of 2012. While we cannot isolate the impact of these programs, we believe the increase in skilled attendants as well as the greater attention to quality that often occurs in teaching programs contributed to the improvements noted.
The results also suggested that the quality of antenatal care as measured by the degree of testing and use of iron and vitamins for all births improved. Cesarean section rates in the study population increased from 13.3% to 24.3% over the 4 years and may have contributed to some of the improvements noted. Babies with birth weights between 1500 and 2499 grams appeared to have the largest reductions in mortality rates, which is consistent with the improved (but not specialized) level of care provided at the Chimaltenango hospital. The largest improvements in mortality rates by place of delivery occurred in babies born in the hospital. The deliveries attended by TBAs did not experience the same decrease in mortality over time as the hospital births. These data suggest that consideration should be given to a policy of phasing out home births with TBAs.
We could not disentangle all the reasons for the decline in mortality which seemed in large part related to increasing use of hospitalization for delivery, increasing cesarean section, fewer TBA deliveries and increased physician deliveries, in addition to the instalation of an NICU and residency programs. We believe that this constellation of interventions along with improvements in prenatal care quality together accounted for the reductions in mortality noted. National changes in clinical care guidelines also explain some of these changes, such as the prophylactic use of antibiotics for all caesarean sections, and of oxytocics for the active management of the third stage of labor.
We observed an increase in the proportion of preterm and low birth weight infants over time. We do not know if this increase actually occurred or was the result of better case ascertainment, related in part to the increase in hospital deliveries. It is notable that the decreases in 28 day neonatal mortality, stillbirths and perinatal mortality occurred despite these increases in the reported preterm and low birth weight babies. Because these babies were at higher risk of mortality, this suggests that the reductions in mortality may have been even greater than our results indicate. Changes in gestational age dating methods, such as increased use of ultrasound, may explain part of the observed increase noted in preterm birth, but would not explain the increase in low-birth weight babies that was observed.
This study had a number of potential limitations. First, although every attempt was made to enrol all pregnant women living in the geographic area, in some of the remote areas, especially early in the study, some deliveries may have been missed. Certain types of data like the maternal BMI were based on data collected during pregnancy and not on reported pre-pregnancy weight and height (as is done in many other studies).
In summary, in a relatively short time period, in the Chimaltenango area of Guatemala which has a history of poor pregnancy outcomes, there were significant improvements in neonatal, fetal and perinatal mortality. These changes were temporally related to major increases in the use of hospitals and skilled birth attendants for delivery, as well as improvements in the quality of delivery care, neonatal care, and prenatal care. Improvements in outcome were greater in facility births and highest in babies weighing 1500 to 2499 grams. It is likely that a smaller proportion of the improvements in outcomes were also due to improvements in maternal educational level and decreased parity of the pregnant population. These observations suggest that rapid improvements in pregnancy outcomes are possible when there is a concerted effort by the Ministry of Health and the medical establishment to improve the health of pregnant women and their newborns.
