Coverage and timing of antenatal care among poor women in 6 Mesoamerican countries

Association between unintended pregnancy and maternal antenatal care services use in Ethiopia: analysis of Ethiopian demographic and health survey 2016

Introduction

Unintended pregnancy disproportionately affects women in low and middle-income countries including Ethiopia. Previous studies identified the magnitude and negative health outcomes of unintended pregnancy. However, studies that examined the relationship between antenatal care (ANC) utilization and unintended pregnancy are scarce.

Objective

This study aimed to examine the relationship between unintended pregnancy and ANC utilization in Ethiopia.

Methods

This is a cross-sectional study conducted using the fourth and most recent Ethiopian Demographic Health Survey (EDHS) data. The study comprised a weighted sample of 7,271 women with last alive birth and responded to questions on unintended pregnancy and ANC use. The association between unintended pregnancy and ANC uptake was determined using multilevel logistic regression models adjusted for possible confounders. Finally p < 5% was considered significant.

Results

Unintended pregnancy accounted for nearly a quarter of all pregnancies (26.5%). After adjusting for confounders, a 33% (AOR: 0.67; 95% CI, 0.57-0.79) lower odds of at least one ANC uptake and a 17% (AOR: 0.83; 95% CI, 0.70-0.99) lower odds of early ANC booking were found among women who had unintended pregnancy compared to women with intended pregnancy. However, this study founds no association (AOR: 0.88; 95% CI, 0.74, 1.04) between unintended pregnancy and four or more ANC visits.

Conclusion

Our study found that having unintended pregnancy was associated with a 17 and 33% reduction in early initiation and use of ANC services, respectively. Policies and programs designed to intervene against barriers to early initiation and use of ANC should consider unintended pregnancy.

The Zika virus: an opportunity to revisit reproductive health needs and disparities

First isolated in 1947, the Zika virus was initially connected only to limited or sporadic human infections. In late 2015, the temporal clustering of a Zika outbreak and microcephaly in newborn babies from northeastern Brazil, and the identification of a causal link between the two, led to the characterization of the congenital Zika syndrome. In the wake of the epidemic, several countries from Latin America advised women to postpone pregnancies for periods ranging from six months to two years. These recommendations initiated critical conversations about the challenges of implementing them in societies with limited access to contraception, widespread socioeconomic inequalities, and high rates of unplanned and adolescent pregnancies. The messaging targeted exclusively women, despite a high prevalence of imbalances in the relationship power, and addressed all women as a group, failing to recognize that the decision to postpone pregnancies will impact different women in different ways, depending on their age at the time. Finally, in several countries affected by the Zika epidemic, due to restrictive reproductive policies, legally terminating a pregnancy is no longer an option even at the earliest time when brain malformations as part of the congenital Zika syndrome can be detected by ultrasonography. The virus continued to circulate after 2016 in several countries. Climate change models predict an expansion of the geographical area where local Zika transmission may occur, indicating that the interface between the virus, teratogenesis, and reproductive rights is a topic of considerable interest for medicine, social sciences, and public health for years to come.

Quality of antenatal care and associated factors in public health centers in Addis Ababa, Ethiopia, a cross-sectional study

Background

Potentially, the risk of morbidity and mortality during pregnancy and child birth can be prevented through comprehensive, quality antenatal care services. The high maternal mortality rate in developing countries, including Ethiopia, is related to poor quality of antenatal care services and is still a major public health problem. The aim of this study is to assess the quality of antenatal care and associated factors in public health centers in Addis Ababa, Ethiopia.

Methods

An institution-based cross-sectional study was conducted using a quantitative method from December 10 to January 30, 2020. A total of 616 study participants were selected by a systematic random sampling technique. Data was collected using pre-tested structured interview administered questionnaires. The data was entered into Epi-info version 7.2.1 and analyzed by SPSS version 24. Bivariate and multivariable logistic regressions were performed to identify the presence and strength of the association between the outcome and predictor variables.

Results

Overall, 33% of pregnant women received good-quality antenatal care. Satisfaction with antenatal care service, antenatal care initiation time, maintaining confidentiality, and waiting time become significant predictors of the quality of antenatal care. As a result, a lack of confidential care (AOR = 0.37; 95% CI, (0.40, 0.88)), a long waiting time (AOR = 0.6, 95% CI, (0.48, 0.88)), and no satisfaction with ANC services (AOR = 0.26; 95% CI, (0.109, 0.36)) were identified as factors impeding the quality of antenatal care. While starting ANC later than four months of pregnancy was found to be a positive predictor of the quality of antenatal care (AOR = 1.9, 95% CI: (1.21, 3.12)).

Conclusion

Only one-third of pregnant mothers received good quality antenatal care. Lack of confidential care, long waiting time and no satisfaction with antenatal care services were factors hindering the quality of antenatal care. While initiation of antenatal care after four months of pregnancy was a positive predictor of the quality of antenatal care.

Effect of unintended pregnancy on skilled antenatal care uptake in Bangladesh: analysis of national survey data

Background

Around 48% of all pregnancies in low- and middle-income countries are unintended. Unintended pregnancy may contribute to lower use of antenatal care (ANC); however, current research in the area is largely inconclusive due to the methodological approaches applied.

Methods

Responses from 4493 women extracted from the 2014 Bangladesh Demographic and Health Survey (BDHS) were used to assess the association between unintended pregnancy and subsequent uptake of at least one and at least four skilled ANC visits. For this, Bayesian multilevel logistic regression models with informative priors (representing a range of values within which the researcher is certain the true effect of the parameters included lies) were used, adjusting for other factors that affect ANC uptake. Informative priors were selected from the BDHS data collected in 2004, 2007, and 2011.

Results

Around 64% of women in Bangladesh who had at least one pregnancy within 3 years prior to the survey (that ended in a live birth) received ANC at least once, and of these around 32% used ANC at least four times. Mistimed (aOR, 0.73, 95% Cred I, 0.66–0.81) and unwanted (aOR, 0.69, 95% Cred I, 0.64–0.75) pregnancy were associated with reduced odds of attending the recommended minimum of four skilled ANC visits compared with wanted pregnancy. These likelihoods were even lower for at least one skilled ANC visit among women with a mistimed (aOR, 0.59, 95% Cred I, 0.53–0.65) or an unwanted pregnancy (aOR, 0.67, 95% Cred I, 0.61–0.74) than women with a wanted pregnancy.

Conclusions

In Bangladesh, more than one-quarter of women who report an unintended pregnancy at conception and do not terminate the pregnancy are at high risk of not using ANC. It is important for policies to include women with unintended pregnancy in mainstream healthcare services. This will increase the use of ANC and reduce associated adverse consequences.

Assessment of Quality of Antenatal Care Services and Its Determinant Factors in Public Health Facilities of Hossana Town, Hadiya Zone, Southern Ethiopia: A Longitudinal Study

Background. Antenatal care is a care that links the woman and her family with the formal health system, increases the chance of using a skilled attendant at birth, and contributes to good health through the life cycle. Inadequate care during this time breaks a critical link in the continuum of care and affects both women and babies. Therefore, the main aim of this study was to determine the quality of ANC in Hadiya Zone, Southern Ethiopia. Method. A longitudinal facility-based study design was conducted among 1123 mothers whose gestational age of less than 16 weeks was identified and followed until birth and 40 days after birth to detect whether they gained the acceptable standard of quality of ANC from July 2017 to June 2018. A structured, predefined, and pretested observation check list and Likert scales were employed to obtain the necessary information after getting both written and verbal consent from the concerned bodies and study participants. Data was entered into Epi Info version 3.5 and transferred to STATA Version 14 software and cleaned by reviewing frequency tables, logical errors, and checking outliers. Generalized estimating equation (GEE) analysis was applied to get the average response observation of each visit of quality of ANC in the health facilities. Result. This study showed that the overall magnitude of good quality of antenatal care service that was provided in the whole visit at Hosanna Town’s public health facilities was 1230 (31.38%). The most frequently identified problems were inability to take full history, lack of proper counseling, poor healthcare provider and client interaction, and improper registration and there was a variation in providing quality of care in each visit. Quality of antenatal care was significantly associated with residence, educational status gravidity, parity, and visit. In conclusion, the overall quality of antenatal care is low, so the health facilities need further modification on the identified problems.

Antenatal care booking within the first trimester of pregnancy and its associated factors among pregnant women residing in an urban area: a cross-sectional study in Debre Berhan town, Ethiopia

OBJECTIVE

This study aimed to assess antenatal care (ANC) booking within the first trimester of pregnancy and its associated factors among urban dwellers of pregnant women in Debre Berhan town, Ethiopia.

DESIGN

Cross-sectional.

SETTING

Public and private health facilities that provide ANC services in Debre Berhan town.

OUTCOME MEASURE

First ANC booking within the first trimester of pregnancy.

PARTICIPANTS

Urban dwellers of pregnant women in Debre Berhan town (n=384).

RESULTS

A total of 387 pregnant women in Debre Berhan town were selected for this study, of which 384 responded giving a response rate of 99.2%. The proportion of pregnant women who had ANC booking within the first trimester of pregnancy was 156 (40.6%; 95% CI: 35.8% to 45.6%). In the multivariable analysis, the odds of first ANC booking within the first trimester was higher among pregnant women who had secondary school (adjusted OR (AOR): 1.84; 95% CI: 1.10 to 3.19) and more than secondary level of education (AOR: 2.26; 95% CI: 1.27 to 4.03) compared with those who had less than a secondary school level of education. Pregnant women who have any ill health with their current pregnancy (AOR: 1.99; 95% CI: 1.21 to 3.27) were more likely to start booking within the first trimester than their counterparts. The odds of ANC booking within the first trimester was threefold higher among women with knowledge of ANC (AOR: 3.05; 95% CI: 1.52 to 6.11) compared with their counterparts.

CONCLUSION

First ANC booking within the first trimester was found to be low among urban dwellers of Debre Berhan town. Secondary school and more educational level, having ill health during early pregnancy and women's knowledge about ANC services were statistically associated with ANC booking within the first trimester of pregnancy. Therefore, improving ANC booking according to the WHO recommendation requires due attention. Further qualitative research exploring why early ANC booking remains low among urban dwellers is important to design intervention modalities.

Timing and number of antenatal care contacts in low and middle-income countries: Analysis in the Countdown to 2030 priority countries

Background

The 2016 World Health Organization (WHO) guidelines for antenatal care (ANC) shift the recommended minimum number of ANC contacts from four to eight, specifying the first contact to occur within the first trimester of pregnancy. We quantify the likelihood of meeting this recommendation in 54 Countdown to 2030 priority countries and identify the characteristics of women being left behind.

Methods

Using 54 Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) since 2012, we reported the proportion of women with timely ANC initiation and those who received 8-10 contacts by coverage levels of ANC4+ and by Sustainable Development Goal (SDG) regions. We identified demographic, socio-economic and health systems characteristics of timely ANC initiation and achievement of ANC8+. We ran four multiple regression models to quantify the associations between timing of first ANC and the number and content of ANC received.

Results

Overall, 49.9% of women with ANC1+ and 44.3% of all women had timely ANC initiation; 11.3% achieved ANC8+ and 11.2% received no ANC. Women with timely ANC initiation had 5.2 (95% confidence interval (CI) = 5.0-5.5) and 4.7 (95% CI = 4.4-5.0) times higher odds of receiving four and eight ANC contacts, respectively (P < 0.001), and were more likely to receive a higher content of ANC than women with delayed ANC initiation. Regionally, women in Central and Southern Asia had the best performance of timely ANC initiation; Latin America and Caribbean had the highest proportion of women achieving ANC8+. Women who did not initiate ANC in the first trimester or did not achieve 8 contacts were generally poor, single women, with low education, living in rural areas, larger households, having short birth intervals, higher parity, and not giving birth in a health facility nor with a skilled attendant.

Conclusions

Timely ANC initiation is likely to be a major driving force towards meeting the 2016 WHO guidelines for a positive pregnancy experience.

Conclusions

Timely ANC initiation is likely to be a major driving force towards meeting the 2016 WHO guidelines for a positive pregnancy experience.

Quality assessment indicators in antenatal care worldwide: a systematic review

PURPOSE

To describe indicators used for the assessment of antenatal care (ANC) quality worldwide under the World Health Organization (WHO) framework and based on a systematic review of the literature.

DATA SOURCES

Searches were performed in MEDLINE, SciELO, BIREME and Web of Science for eligible studies published between January 2002 and September 2016.

STUDY SELECTION

Original articles describing women who had received ANC, any ANC model and, any ANC quality indicators were included.

DATA EXTRACTION

Publication date, study design and ANC process indicators were extracted.

RESULTS OF DATA SYNTHESIS

Of the total studies included, 69 evaluated at least one type of ANC process indicator. According to WHO ANC guidelines, 8.7% of the articles reported healthy eating counseling and 52.2% iron and folic acid supplementation. The evaluation indicators on maternal and fetal interventions were: syphilis testing (55.1%), HIV testing (47.8%), gestational diabetes mellitus screening (40.6%) and ultrasound (27.5%). Essential ANC activities assessment ranged from 26.1% report of fetal heart sound, 50.7% of maternal weight and 63.8% of blood pressure. Regarding preventive measures recommended by WHO, tetanus vaccine was reported in 60.9% of the articles. Interventions performed by health services to improve use and quality of ANC care, promotion of maternal and fetal health, and the number of visits to the ANC were evaluated in 65.2% of the studies.

CONCLUSION

Numerous ANC content indicators are being used to assess ANC quality. However, there is a need to use standardized indicators across countries and efforts to improve quality evaluation.

The shift of obesity burden by socioeconomic status between 1998 and 2017 in Latin America and the Caribbean: a cross-sectional series study

BACKGROUND

The burden of obesity differs by socioeconomic status. We aimed to characterise the prevalence of obesity among adult men and women in Latin America and the Caribbean by socioeconomic measures and the shifting obesity burden over time.

METHODS

We did a cross-sectional series analysis of obesity prevalence by socioeconomic status by use of national health surveys done between 1998 and 2017 in 13 countries in Latin America and the Caribbean. We generated equiplots to display inequalities in, the primary outcome, obesity by wealth, education, and residence area. We measured obesity gaps as the difference in percentage points between the highest and lowest obesity prevalence within each socioeconomic measure, and described trends as well as changing patterns of the obesity burden over time.

FINDINGS

479 809 adult men and women were included in the analysis. Obesity prevalence across countries has increased over time, with distinct patterns emerging by wealth and education indices. In the most recent available surveys, obesity was most prevalent among women in Mexico in 2016, and the least prevalent among women in Haiti in 2016. The largest gap between the highest and lowest obesity estimates by wealth was observed in Honduras among women (21·6 percentage point gap), and in Peru among men (22·4 percentage point gap), compared with a 3·7 percentage point gap among women in Brazil and 3·3 percentage points among men in Argentina. Urban residents consistently had a larger burden than their rural counterparts in most countries, with obesity gaps ranging from 0·1 percentage points among women in Paraguay to 15·8 percentage points among men in Peru. The trend analysis done in five countries suggests a shifting of the obesity burden across socioeconomic groups and different patterns by gender. Obesity gaps by education in Mexico have reduced over time among women, but increased among men, whereas the gap has increased among women but remains relatively constant among men in Argentina.

INTERPRETATION

The increase in obesity prevalence in the Latin American and Caribbean region has been paralleled with an unequal distribution and a shifting burden across socioeconomic groups. Anticipation of the establishment of obesity among low socioeconomic groups could provide opportunities for societal gains in primordial prevention.

Effects of unintended pregnancy on maternal healthcare services utilization in low- and lower-middle-income countries: systematic review and meta-analysis

OBJECTIVES

To examine the association between unintended pregnancy and maternal healthcare services utilization in low- and lower-middle-income countries.

METHODS

A systematic literature search of Medline, Cinahl, Embase, PsycINFO, Cochrane Library, Popline, Maternity and Infant Care, and Scopus databases published since the beginning of the Millennium Development Goals (i.e. January 2000) to June 2018 was performed. We estimated the pooled odds ratios using random effect models and performed subgroup analysis by participants and study characteristics.

RESULTS

A total of 38 studies were included in the meta-analysis. Our study found the occurrence of unintended pregnancy was associated with a 25-39% reduction in the use of antenatal, delivery, and postnatal healthcare services. Stratified analysis found the differences of healthcare services utilization across types of pregnancy unintendedness (e.g. mistimed, unwanted).

CONCLUSIONS

Integrating family planning and maternal healthcare services should be considered to encourage women with unintended pregnancies to access maternal healthcare services.

Antenatal care as a means to increase participation in the continuum of maternal and child healthcare: an analysis of the poorest regions of four Mesoamérican countries

Background

Antenatal care (ANC) is a means to identify high-risk pregnancies and educate women so that they might experience a healthier delivery and outcome. There is a lack of evidence about whether receipt of ANC is an effective strategy for keeping women in the system so they partake in other maternal and child interventions, particularly for poor women. The present analysis examines whether ANC uptake is associated with other maternal and child health behaviors in poor mothers in Guatemala, Honduras, Nicaragua, and Mexico (Chiapas).

Methods

We conducted a cross-sectional survey of women regarding their uptake of ANC for their most recent delivery in the last two years and their uptake of selected services and healthy behaviors along a continuity of maternal and child healthcare. We conducted logistic regressions on a sample of 4844 births, controlling for demographic, household, and maternal characteristics to understand the relationship between uptake of ANC and later participation in the continuum of care.

Results

Uptake of four ANC visits varied by country from 17.0% uptake in Guatemala to 81.4% in Nicaragua. In all countries but Nicaragua, ANC was significantly associated with in-facility delivery (IFD) (Guatemala odds ratio [OR] = 5.28 [95% confidence interval [CI] 3.62–7.69]; Mexico OR = 5.00 [95% CI: 3.41–7.32]; Honduras OR = 2.60 [95% CI: 1.42–4.78]) and postnatal care (Guatemala OR = 4.82 [95% CI: 3.21–7.23]; Mexico OR = 4.02 [95% CI: 2.77–5.82]; Honduras OR = 2.14 [95% CI: 1.26–3.64]), but did not appear to have any positive relationship with exclusive breastfeeding habits or family planning methods, which may be more strongly determined by cultural influences.

Conclusions

Our results demonstrate that uptake of the WHO-recommended four ANC visits has limited effectiveness on uptake of services in some poor populations in Mesoamérica. Our study highlights the need for continued and varied efforts in these populations to increase both the uptake and the effectiveness of ANC in encouraging positive and lasting effects on women’s uptake of health care services.

The association of prenatal risk factors with childhood asthma

Objective: The purpose of the study was to examine the relationship of maternal complications during pregnancy and prenatal exposures with childhood asthma among low-income families in Karachi, Pakistan. Methods: Parents/guardians of children with and without asthma visiting a charity hospital were enrolled. Information about prenatal and perinatal exposures was collected. Univariable and multiple stepwise logistic regression analysis were conducted to explore the relationship of socio-demographic, maternal complications during pregnancy, access to prenatal care, and exposure to animals and pests while pregnant with childhood asthma. Results: Maternal symptoms of nocturnal cough (adjusted OR [aOR = 2.87, 95% CI = 1.60-5.14) and wheezing (aOR = 5.57, 95% CI = 2.32-13.37) during pregnancy significantly increased the odds of childhood asthma. The family history of asthma or hay fever, also elevated the odds of childhood asthma (adjusted OR [aOR] = 5.86 (3.03-11.34). The odds of asthma among children whose mothers received prenatal care by Dai, an unskilled health worker, were significantly elevated. Lastly, prenatal exposure to rats/mice and contact with goats while pregnant was significantly associated with childhood asthma. Whereas, prenatal exposure to cows/cattle reduces the odds of childhood asthma. Conclusions: This study identified important maternal and prenatal risk factors for childhood asthma, the majority of which are avoidable. Appropriate steps are needed to create awareness about the prenatal risk factors in this population.

Preventable perinatal deaths in indigenous Wixárika communities: an ethnographic study of pregnancy, childbirth and structural violence

BACKGROUND

Preventable maternal and infant mortality continues to be significantly higher in Latin American indigenous regions compared to non-indigenous, with inequalities of race, gender and poverty exacerbated by deficiencies in service provision. Standard programmes aimed at improving perinatal health have had a limited impact on mortality rates in these populations, and state and national statistical data and evaluations of services are of little relevance to the environments that most indigenous ethnicities inhabit. This study sought a novel perspective on causes and solutions by considering how structural, cultural and relational factors intersect to make indigenous women and babies more vulnerable to morbidity and mortality.

METHODS

We explored how structural inequalities and interpersonal relationships impact decision-making about care seeking during pregnancy and childbirth in Wixarika communities in Northwestern Mexico. Sixty-two women were interviewed while pregnant and followed-up after the birth of their child. Observational data was collected over 18 months, producing more than five hundred pages of field notes.

RESULTS

Of the 62 women interviewed, 33 gave birth at home without skilled attendance, including 5 who delivered completely alone. Five babies died during labour or shortly thereafter, we present here 3 of these events as case studies. We identified that the structure of service provision, in which providers have several contiguous days off, combined with a poor patient-provider dynamic and the sometimes non-consensual imposition of biomedical practices acted as deterrents to institutional delivery. Data also suggested that men have important roles to play supporting their partners during labour and birth.

CONCLUSIONS

Stillbirths and neonatal deaths occurring in a context of unnecessary lone and unassisted deliveries are structurally generated forms of violence: preventable morbidities or mortalities that are the result of systematic inequalities and health system weaknesses. These results counter the common assumption that the choices of indigenous women to avoid institutional delivery are irrational, cultural or due to a lack of education. Rather, our data indicate that institutional arrangements and interpersonal interactions in the health system contribute to preventable deaths. Addressing these issues requires important, but achievable, changes in service provision and resource allocation in addition to long term, culturally-appropriate strategies.

Determining gestational age and preterm birth in rural Guatemala: A comparison of methods

Background

Preterm birth is the leading cause of death among children <5 years of age. Accurate determination of prematurity is necessary to provide appropriate neonatal care and guide preventive measures. To estimate the most accurate method to identify infants at risk for adverse outcomes, we assessed the validity of two widely available methods—last menstrual period (LMP) and the New Ballard (NB) neonatal assessment—against ultrasound in determining gestational age and preterm birth in highland Guatemala.

Methods

Pregnant women (n = 188) were recruited with a gestational age <20 weeks and followed until delivery. Ultrasound was performed by trained physicians and LMP was collected during recruitment. NB was performed on infants within 96 hours of birth by trained study nurses. LMP and NB accuracy at determining gestational age and identifying prematurity was assessed by comparing them to ultrasound.

Results

By ultrasound, infant mean gestational age at birth was 38.3 weeks (SD = 1.6) with 16% born at less than 37 gestation. LMP was more accurate than NB (mean difference of +0.13 weeks for LMP and +0.61 weeks for NB). However, LMP and NB estimates had low agreement with ultrasound-determined gestational age (Lin’s concordance<0.48 for both methods) and preterm birth (κ<0.29 for both methods). By LMP, 18% were judged premature compared with 6% by NB. LMP underestimated gestational age among women presenting later to prenatal care (0.18 weeks for each additional week). Gestational age for preterm infants was overestimated by nearly one week using LMP and nearly two weeks using NB. New Ballard neuromuscular measurements were more predictive of preterm birth than those measuring physical criteria.

Conclusion

In an indigenous population in highland Guatemala, LMP overestimated prematurity by 2% and NB underestimated prematurity by 10% compared with ultrasound estimates. New, simple and accurate methods are needed to identify preterm birth in resource-limited settings worldwide.

The use of long-acting reversible contraceptives in Latin America and the Caribbean: current landscape and recommendations

STUDY QUESTION

Can the high rate and associated burden of unintended pregnancy (UP) and adolescent pregnancy in Latin America and the Caribbean (LAC) be reduced through wider access to and use of long-acting reversible contraceptive (LARC) methods?

SUMMARY ANSWER

Studies show that impoved access to and use of LARC methods is an effective tool for reducing the high rates of UP, unsafe abortion and abortion-related complications, and maternal deaths (as well as reducing their social and financial burden), and we have provided recommendations to help achieve this in LAC.

WHAT IS KNOWN ALREADY

LAC comprises 46 countries with 650 million inhabitants, and shows large disparities in socioeconomic development, access to health services and attention to sexual and reproductive health rights. The exercise of these rights and universal access to sexual and reproductive health (SRH) programmes is a key strategy for improving maternal health by reducing the number of UPs, the rate of women's and child mortality and morbidity, and the number of unsafe abortions. The implementation of SRH programmes in the region has contributed to a decrease in pregnancy rates of more than 50% over 40 years. However, despite this progress, the numbers of UP and adolescent pregnancies are still among the highest worldwide, which can be attributed in large part to the low prevalence of use of LARC methods.

STUDY DESIGN SIZE DURATION

This is a position paper with the objective of reviewing the magnitude and burden of UP in LAC, as well as available LARC methods and barriers to their access, with the goal of increasing knowledge and awareness among healthcare professionals (HCP), policymakers and the general public about the potential to reduce UP rates through the increased use of LARC.

PARTICIPANTS/MATERIALS SETTING METHOD

We searched the electronic databases of PubMed and EMBASE to identify studies published up to May 2017. We also searched for websites regarding LAC, LARC methods, and UP including, for example, those from the United Nations, the World Health Organization, Pan American Health Organization, the Alan Guttmacher Institute and the United States Agency for International Development. Studies were included if they investigated mainly UP and their consequences as well as the use of LARC methods in the region. During 3 days of meetings, the importance of the studies identified and the appropriateness of inclusion were discussed.

MAIN RESULTS AND THE ROLE OF CHANCE

LAC is not one unit and shows great ethnic diversity as well as economic and cultural differences among the various countries. These differences must be taken into account when developing policies related to disseminating information and combatting misinformation regarding the use of LARC among different audiences, such as adolescents and young women, nulligravidas, indigenous populations and women with disabilities. Furthermore, only some governments have made efforts to increase accessibility to LARC methods, and there is a need to implement training programmes for HCPs, launch education campaigns for the general public, increase access and review the cost-benefit analyses specific to LARC, which have already demonstrated that the upfront cost of LARC is less than the cummulative expense of short-term contraceptives. Recommendations to achieve these goals are presented.

LIMITATIONS REASONS FOR CAUTION

Knowledge and awareness of the contraceptive method itself and of the mix of individual countries in the region is essential to the development of specific strategies and actions, tailored to each particular country situation, aimed at increasing access to modern contraceptive methods, especially LARC.

WIDER IMPLICATIONS OF THE FINDINGS

Healthcare systems in LAC should consider LARC as a primary option for decreasing UP and adolescent pregnancy. Disseminating information, increasing awareness of their efficacy, removing barriers and improving access to LARC methods are the urgent actions recommended for government, academia, professional organizations, insurance companies and policymakers in order to address this major public health problem in LAC.
