Maternal and perinatal outcomes among nulliparous adolescents in low- and middle-income countries: a multi-country study

Comparison of the pregnancy results between adolescent Syrian refugees and local adolescent Turkish citizens who gave birth in our clinic

Adolescence is the transition period from childhood to adulthood; the World Health Organization has defined it as the ages between 10 and 19. Approximately 11% of all births in the world are by adolescent mothers. Pregnant adolescent refugees who have been forced to emigrate due to civil wars raging on in their native countries often face difficult social life conditions, have little or no access to hospitals, and experience language barriers and poor nutritional status have been found to experience poor maternal and obstetric outcomes. These include an increase in cesarean births, premature births, intrauterine growth retardation, and low-birth-weight infant rates. The purpose of the article was to share with you the comparative results of the adolescent pregnancies among the immigrants and among the local adolescents who gave birth between January 2016 and July 2017 in Kocaeli Derince Training and Research Hospital Gynecology Clinic in Kocaeli, Turkey. Its materials and method is a comparative study planned retrospectively between 67 adolescent Syrian refugees and 188 adolescent Turkish locals who gave birth between January 2016 and July 2017. The demographic data, obstetric outcomes, hospitalization durations, and neonatal outcomes of the patients were compared between the groups. Results, no statistically significant difference was found between pregnancy numbers, normal birth rates, cesarean sections and interventional birth rates, nullipara-multipara birth rates, or premature birth rates (<37 weeks) of the pregnant Turkish adolescents and pregnant immigrant adolescents (p > .05). The number of days these patients were hospitalized was found to be lower among Syrian immigrants than among the Turkish locals and statistically significant (p = .045 and p < .05, respectively). In addition, an analysis of the birth rates of low-birth-weight infants revealed that said rates were higher among the Syrian refugees than the Turkish local and statistically borderline significant (p = .049, p < .05, respectively). Between January 2016 and July 2017, a total of 8,570 live births were performed in our clinic. In our study of the 255 patients under the age of 19 who gave live births, 188 were Turkish and 67 were Syrian refugees. The average age of Turkish mothers under 19 was found to be 17.30 ± 1.01 years and the average age of immigrant mothers was found to be 17.27 ± 0.82 years. In conclusion, adolescent pregnancies are more common among Syrian refugees. Adolescent pregnancies are at risk for obstetric and neonatal outcomes. Therefore, studies should be done to prevent these pregnancies.

Iranian mothers' experiences of the outcomes of early motherhood: A qualitative study

Early motherhood is a major health challenge in most developing countries. The aim of this study was to explore Iranian mothers' experiences of the outcomes of early motherhood. This qualitative study was done using the conventional inductive content analysis approach. A purposive sample of 18 Iranian mothers, with the experience of early motherhood, was recruited with maximum variation in terms of their age at their first pregnancy, their children's age, place of residence, and financial status. Data collection was done via in-depth semistructured interviews and continued up to data saturation. The MAXQDA software (v. 10.0) was employed for handling the data. Iranian mothers' experiences of the outcomes of early motherhood came into two main categories that were named "realization of the childhood dream of adulthood" and "heavy burden of adulthood on the small shoulders of childhood," The four subcategories of the first category were the acceleration of intellectual and mental maturation, strengthening of family relationships, developing a strong identity, and closer companionship with the child. The second main category also included four subcategories, namely, experiencing numerous difficulties, threats to mothers' physical and mental health, threats to children's health, and missing opportunities. Early motherhood is not merely a negative experience; rather it is also associated with different positive outcomes. Healthcare providers need to provide high-quality prenatal, perinatal, and postnatal care services to adolescent mothers and use available opportunities to strongly support them and their children.

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.

[Factors associated with first pregnancy in women who gave birth in a maternity hospital in Antananarivo: a retrospective cohort study]

Introduction

Il y a très peu de littératures africaines et Malgaches concernant les détails sur les facteurs de risques qu'encourent les primigestes en général. Le but de notre étude est de déterminer les facteurs de risques potentiels associés à une première grossesse.

Méthodes

Une étude cohorte rétrospective a été menée auprès des femmes primigestes et multigestes de l'hôpital Pavillon sainte Fleur entre Octobre 2014 et Décembre 2016. Les risques relatifs étaient ajustés après contrôle avec les caractéristiques sociodémographiques.

Résultats

Les primigestes étaient beaucoup plus exposées à un travail prolongé de plus de 12h (RRa = 2,28; IC 95% 1,74-3,00), à une césarienne en urgence (RRa = 1,47; IC 95% 1,35-1,60) et à une épisiotomie (RRa = 2,98; IC 95% 2,61-3,40). Leurs enfants étaient plus susceptibles de présenter des signes de souffrance fœtale avec anomalie du rythme cardiaque fœtale au cours de la phase de travail (RRa = 1,96; IC 95% 1,45-2,65) et un risque accru d'être admis dans une unité de soins intensifs après l'accouchement (RRa = 2,08; IC 95% 1,25-3,45).

Conclusion

Les complications survenues pendant le travail auraient exposé les primigestes à d'autres risques en cascades sur l'issue de leurs accouchements et sur la santé de leurs enfants. La prise en charge des primigestes nécessiterait, de la part des personnels médicaux, une attention particulière sur la durée de la phase de travail.

The long-term effects of adolescent pregnancies in a community in Northern Ghana on subsequent pregnancies and births of the young mothers

Background

In Ghana, adolescents represent 22% of the total population. The rates of adolescent pregnancies are high. Of all births registered in the country in 2014, 30% were by adolescents, and 14% of adolescents aged between 15 and 19 years had begun childbearing. Pregnancies and deliveries of adolescents are accompanied by more risks as compared to older women. The aim of the study was to explore the long-term effects of adolescent pregnancies on subsequent pregnancies and births and on the socioeconomic status of the women.

Method

A cross-sectional interviewer-performed survey of a purposive sample of 400 women in one community of Northern Ghana was conducted. Relationships between the age at first pregnancy and complications such as cesarean section, preterm or stillbirth and others were explored in 143 patients using the statistical program SPSS (Statistical Package for the Social Sciences).

Result

Results show that adolescent women (<19 years at their first pregnancy) have an 80% higher risk for a cesarean section for the first and subsequent births as compared to older women (≥ 19 years). Furthermore, younger mothers have a 45% higher risk of stillbirths and a 30% increased risk of losing their baby within the first 6 weeks after birth. There was no difference in the socioeconomic status between the two age groups.

Conclusion

Adolescent pregnancies are risk factors for the outcome of subsequent pregnancies of these mothers. This study, for the first time, shows that not only the first pregnancy and birth of very young women are negatively influenced by the early pregnancy but also subsequent pregnancies and births. While this study is of a purposive sample of women in one community, the clinical relevance of this study should not only be interesting for healthcare practitioners in Northern Ghana and other African regions but also for prevention campaigns in these regions.

Prevalence, predictors and adverse outcomes of adolescent pregnancy in sub-Saharan Africa: a protocol of a systematic review

BACKGROUND

Several studies have reported on factors influencing adolescent pregnancies and the associated outcomes, but evidence from a systematic review is limited, especially in sub-Saharan Africa where the greater burden lies. Establishment of accurate epidemiological data on the rates of adolescent pregnancy, its predictors, and adverse outcomes (maternal and neonatal) may have important implications towards attainment of the Sustainable Development Goals.

METHODS

This will be a systematic review of studies reporting predictors of adolescent pregnancy and adverse outcomes in sub-Saharan Africa published between January 2000 and December 2017. The following databases will be searched: PubMed/MEDLINE, Excerpta Medica Database (EMBASE), SCOPUS, Popline, Africa Wide Information, African Index Medicus, Google scholar and the Cochrane library. Three authors will independently screen all potential articles for eligibility as guided by the selection criteria. The Stata statistical software will be used in analysing the data. Appropriate meta-analytic techniques will be used to pool prevalence estimates from studies with similar features, overall and by major subgroups as warranted. Heterogeneity of studies will be evaluated by the χ ² test on Cochrane's Q statistic. Publication bias will be sorted for using funnel plot analysis and Egger's test. Qualitative synthesis will be used where data are insufficient to produce a quantitative synthesis. This protocol is reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) 2015 guidelines.

DISCUSSION

This systematic review and meta-analysis is expected to serve as a template for designing adolescent-friendly preventive and control programmes to help curb the ever-growing burden of adolescent pregnancies, and as a guide for future research.

Adolescent pregnancy and nutrition: a subgroup analysis from the Mamachiponde study in Malawi

Young age at childbearing (≤19 years) is common and associated with poor birth outcomes. A trial among Malawian pregnant women with moderate malnutrition was used to determine outcomes of young adolescents (≤18 years), older adolescents (18-20 years), and adults (>20 years). Women received one of three supplementary foods that provided ∼900 kcal/day and 33-36 g protein/day and returned every 2 weeks. Newborn/maternal measurements were taken at delivery and after 6 and 12 weeks. Upon enrollment, adolescents had greater body mass index than adults (19.9 ± 1.3 versus 19.5 ± 1.4 kg/m2 , P < 0.001). Young adolescents received more rations of food and enrolled and delivered with a lower fundal height than adults (21.7 ± 5.2 versus 23.0 ± 5.6, P = 0.00 enrollment; 30.2 ± 3.1 versus 31.0 ± 2.8, P < 0.001 delivery). Among newborns, length for age was lowest in young adolescents, greater in older adolescents, and greatest in adults (Z-scores -1.7 ± 1.2, -1.4 ± 1.2, and -1.1 ± 1.1, respectively; P < 0.001). These differences persisted in length for age at 6 and 12 weeks of age for infants. Adolescents enrolled earlier in pregnancy and appeared more nutritionally adequate than adults; adolescent outcomes were inferior to those of adults, suggesting that they were subject to more physiologic stressors and/or different nutritional needs.

Linear association between maternal age and need of medical interventions at delivery in primiparae: a cohort of 21,235 singleton births

OBJECTIVES

We sought to investigate the potential association between maternal age and the need for active obstetrical intervention intrapartum in primiparas.

STUDY DESIGN

Observational study over 14 years (2001-2014) of all consecutive primiparous singleton births having delivered at the Centre Hospitalier Universitaire Hospitalier Sud Reunion's maternity (French overseas department, Indian Ocean).

RESULTS

Of the 21,235 singleton primiparous births, there were three significant linear associations between maternal age from 12 years of age to 42 + (all χ² for linear trend, p < .0001) (a) vaginal deliveries without any medical intervention, (b) rate of cesarean sections, and (c) rate of operative vaginal procedures. These three linear associations persisted when controlling for maternal obesity (±30 kg/m²), "heavy babies" (>3.5 kg), and ethnicity. Using maternal age remained significantly an independent risk factor (p < .0001), after controlling for the major confounders: maternal BMI, maternal height, birthweight ≥3500 g, p < .0001.

CONCLUSIONS

Increasing maternal age has a linear association with vaginal deliveries without any medical intervention, rate of cesarean sections, and rate of operative vaginal procedures. These associations are independent of maternal BMI and maternal height. We currently do not have a specific explanation why younger women appear to be protected from requiring intrapartum obstetric intervention. Nevertheless, these strong facts deserve acknowledgement and further research.

Impact of donor and recipient adiposity on placental and fetal growth in adolescent sheep

The influence of maternal obesity during oocyte development and its putative interaction with nutrient reserves at conception on pregnancy outcome were examined in an adolescent sheep model. Donor ewes were nutritionally managed to achieve contrasting adiposity (control (CD)/obese (ObD)) for 6 weeks prior to superovulation and inseminated by a non-obese sire. Morulae from 6 CD and 7 ObD were transferred in singleton into adolescent recipients of identical age but differing adiposity, classified as relatively fat or thin respectively. Thereafter, all were overnourished to promote rapid growth/adiposity (2 × 2 design, 13/14 pregnancies/group). A fifth recipient group of intermediate adiposity received embryos from another 5 CD, was offered a moderate intake to maintain adiposity throughout gestation and acted as controls for normal pregnancy outcome (optimally treated control (OTC), 19 pregnancies). Donor obesity did not influence ovulation, fertilisation or recovery rates or impact embryo morphology. Gestation length and colostrum yield were unaffected by donor or recipient adiposity and were reduced relative to OTC. Total fetal cotyledon and lamb birth weights were independent of initial donor adiposity but reduced in relatively thin vs relatively fat recipients and lower than those in the OTC group. In spite of high placental efficiency, the incidence of fetal growth restriction was greatest in the thin recipients. Thus, maternal adiposity at conception, but not pre-conception maternal obesity, modestly influences the feto-placental growth trajectory, whereas comparison with the OTC indicates that high gestational intakes to promote rapid maternal growth remain the dominant negative influence on pregnancy outcome in young adolescents. These findings inform dietary advice for pregnant adolescent girls.

Lower education among low-income Brazilian adolescent females is associated with planned pregnancies

Adolescent pregnancy has social, economic, and educational consequences and is also linked to adverse perinatal outcomes. However, studies show a positive relationship between pregnancy and increased social status among low-income adolescents. This study aims to assess the association between planned pregnancy and years of schooling among low-income Brazilian adolescents. This is a secondary analysis of a cohort study conducted from May 2005 to March 2007 in public primary care clinics in São Paulo, Brazil. Participants (n=168) completed a detailed structured questionnaire. Logistic regression was used to examine the association between years of schooling and planned pregnancy. After adjusting for the covariates income, wealth score, crowding, age, marital status, and race, planned pregnancy was independently associated with lower years of education (odds ratio: 1.82; 95% confidence interval: 1.02–3.23). Although this finding may be related to these adolescents having less access to information and health services, another possible explanation is that they have a greater desire to have children during adolescence.

Effectiveness of a girls' empowerment programme on early childbearing, marriage and school dropout among adolescent girls in rural Zambia: study protocol for a cluster randomized trial

Background

Adolescent pregnancies pose a risk to the young mothers and their babies. In Zambia, 35% of young girls in rural areas have given birth by the age of 18 years. Pregnancy rates are particularly high among out-of-school girls. Poverty, low enrolment in secondary school, myths and community norms all contribute to early childbearing. This protocol describes a trial aiming to measure the effect on early childbearing rates in a rural Zambian context of (1) economic support to girls and their families, and (2) combining economic support with a community intervention to enhance knowledge about sexual and reproductive health and supportive community norms.

Methods/design

This cluster randomized controlled trial (CRCT) will have three arms. The clusters are rural schools with surrounding communities. Approximately 4900 girls in grade 7 in 2016 will be recruited from 157 schools in 12 districts. In one intervention arm, participating girls and their guardians will be offered cash transfers and payment of school fees. In the second intervention arm, there will be both economic support and a community intervention. The interventions will be implemented for approximately 2 years. The final survey will be 4.5 years after recruitment. The primary outcomes will be “incidence of births within 8 months of the end of the intervention period”, “incidence of births before girls’ 18th birthday” and “proportion of girls who sit for the grade 9 exam”. Final survey interviewers will be unaware of the intervention status of respondents. Analysis will be by intention-to-treat and adjusted for cluster design and confounders. Qualitative process evaluation will be conducted.

Discussion

This is the first CRCT to measure the effect of combining economic support with a community intervention to prevent adolescent childbearing in a low- or middle-income country. We have designed a programme that will be sustainable and feasible to scale up. The findings will be relevant for programmes for adolescent reproductive health in Zambia and similar contexts.

Community social capital on the timing of sexual debut and teen birth in Nicaragua: a multilevel approach

Background

Community attributes have been gradually recognized as critical determinants shaping sexual behaviors in young population; nevertheless, most of the published studies were conducted in high income countries. The study aims to examine the association between community social capital with the time to sexual onset and to first birth in Central America.

Methods

Building upon the 2011/12 Demographic and Health Survey conducted in Nicaragua, we identified a sample of 2766 community-dwelling female adolescents aged 15 to 19 years. Multilevel survival analyses were performed to estimate the risks linked with three domains of community social capital (i.e., norms, resource and social network).

Results

Higher prevalence of female sexual debut (norms) and higher proportion of secondary school or higher education (resource) in the community are associated with an earlier age of sexual debut by 47 % (p < 0.05) and 16 %, respectively (p < 0.001). Living in a community with a high proportion of females having a child increases the hazard of teen birth (p < 0.001) and resource is negatively associated with teen childbearing (p < 0.05). Residential stability and community religious composition (social network) were not linked with teen-onset sex and birth.

Conclusions

The norm and resource aspects of social capital appeared differentially associated with adolescent sexual and reproductive behaviors. Interventions aiming to tackle unfavorable sexual and reproductive outcomes in young people should be devised and implemented with integration of social process.

Risk-profiles and outcomes of multi-foetal pregnancies in adolescent mothers

In this retrospective review of 468 mothers with a multi-foetal pregnancy in Detroit, we describe the risk-profiles and the obstetrical, maternal and foetal outcomes of multi-foetal pregnancy in 59 (13%) adolescents. Overall, most mothers were African American, did not have private insurance and all were unmarried. For most mothers, this was their first pregnancy (59.3%) and their first delivery (69.5%). Almost 50% presented to triage at least once during their pregnancy. Anaemia (78%) and hypertensive disorders (18.6%) were common in this age group. The majority of adolescents delivered preterm as 81.4% were <37 weeks and 49% were <34 weeks. Furthermore, the majority of infants (79%) had low birth weights (median: 1975 g, range: 365-3405 g). This contemporary report emphasises the need for multidisciplinary prenatal management and specialist supervision, as multi-foetal pregnancies in adolescents pose real risks and impact obstetrical, maternal and neonatal outcomes.

Interventions to Prevent Unintended and Repeat Pregnancy Among Young People in Low- and Middle-Income Countries: A Systematic Review of the Published and Gray Literature

Adolescent pregnancy, particularly unintended pregnancy, can have lasting social, economic, and health outcomes. The objective of this review is to identify high-quality interventions and evaluations to decrease unintended and repeat pregnancy among young people in low- and middle-income countries. PubMed, Embase, PsycInfo, Cinahl Plus, Popline, and the Cochrane Databases were searched for all languages for articles published through November 2015. Gray literature was searched by hand. Reference tracing was utilized, as well as unpacking systematic reviews. Selected articles were those that were evaluated as having high-quality interventions and evaluations using standardized scoring. Twenty-one high-quality interventions and evaluations were abstracted. Nine reported statistically significant declines in pregnancy rates (five cash transfer programs, one education curriculum, two life-skills curricula, and a provision of contraception intervention), seven reported increases in contraceptive use (three provision of contraception interventions, two life-skills curricula, a peer education program, and a mass media campaign), two reported decreases in sexual activity (a cash transfer program and an education and life-skills curriculum), and two reported an increase in age of sexual debut (both cash transfer programs). The selected high quality, effective interventions included in this review can inform researchers, donors, and policy makers about where to make strategic investments to decrease unintended pregnancy during young adulthood. Additionally, this review can assist with avoiding investments in interventions that failed to produce significant impact on the intended outcomes. The diversity of successful high-quality interventions, implemented in a range of venues, with a diversity of young people, suggests that there are multiple strategies that can work to prevent unintended pregnancy.

Role of birth spacing, family planning services, safe abortion services and post-abortion care in reducing maternal mortality

Access to contraception reduces maternal deaths by preventing or delaying pregnancy in women who do not intend to be pregnant or those at higher risk of complications. However, not all unintended pregnancies can be prevented through increase in contraceptive use, and access to safe abortion is needed to prevent unsafe abortions. Despite not preventing the problem, provision of emergency care for complications can help prevent deaths from such unsafe abortions. Safe abortion in early pregnancy can be provided at primary care level and by non-physician providers, and the risks of mortality associated with such safe, legal abortions are minimal. Although entirely preventable, unsafe abortions continue to occur because of numerous barriers such as legal and policy restrictions, service delivery issues and provider attitudes to abortion stigma. Overall, the provision of contraception and safe abortion is important not just to prevent maternal deaths but as a measure of our ability to respect women's decisions and ensure that they have access to timely, evidence-based care that protects their health and human rights.

Maternal and Perinatal Outcomes Among Adolescents and Mature Women: A Hospital-Based Study in the North of Mexico

STUDY OBJECTIVE

To compare maternal and newborn pregnancy outcomes from adolescents and mature women.

DESIGN, SETTING, AND PARTICIPANTS

A cross-sectional study was carried out in a public hospital, including women with singleton pregnancies, who were classified according to their age, as follows: group 1: younger than 16 years old (n = 37), group 2: 16-19 years old (n = 288), and group 3: 20-34 years old (n = 632).

INTERVENTIONS AND MAIN OUTCOME MEASURES

Information on clinical characteristics, gynecological and obstetric history, pregnancy complications, and perinatal outcomes was obtained through interviews and from clinical records.

RESULTS

Thirty-four percent of deliveries were from adolescents. Mature women were more likely to have prepregnancy overweight or obesity than adolescents (odds ratio [OR] = 2.4, 95% confidence interval [CI], 1.7-3.4). The frequency of maternal complications during pregnancy or delivery was not different between groups. Birth asphyxia was more frequent in group 2 (P = .02). Women with inadequate prenatal care had an increased risk of preterm deliveries (OR = 1.64; 95% CI, 1.06-2.54) and of having newborns with low birth weight (OR = 2.02; 95% CI, 1.22-3.35). Weight of newborns from noncomplicated pregnancies was lower in group 1 (P = .02), after adjustment for prepregnancy body mass index, gestational weight gain, preterm delivery, and newborn sex.

CONCLUSION

The frequency of maternal and perinatal complications was similar in adolescents and mature women. Birth weight was decreased in noncomplicated pregnancies of adolescents younger than 16 years of age. Adequate prenatal care might be helpful in prevention of some adverse perinatal outcomes.

Extraordinary intelligence and the care of infants

We present evidence that pressures for early childcare may have been one of the driving factors of human evolution. We show through an evolutionary model that runaway selection for high intelligence may occur when (i) altricial neonates require intelligent parents, (ii) intelligent parents must have large brains, and (iii) large brains necessitate having even more altricial offspring. We test a prediction of this account by showing across primate genera that the helplessness of infants is a particularly strong predictor of the adults' intelligence. We discuss related implications, including this account's ability to explain why human-level intelligence evolved specifically in mammals. This theory complements prior hypotheses that link human intelligence to social reasoning and reproductive pressures and explains how human intelligence may have become so distinctive compared with our closest evolutionary relatives.

Characteristics and risk factors of preterm births in a tertiary center in Lagos, Nigeria

Introduction

Preterm birth is a dire complication of pregnancy that poses huge long-term medical and financial burdens for affected children, their families, and the health care system. The aim of the present study was to identify characteristics associated with preterm births at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria from 2011 to 2013.

Methods

We obtained Information from 5,561 maternal, fetal/neonatal and obstetric records from the labor ward. We excluded delivery at less than 22 weeks (0.25%), post-term birth at ≥42 weeks gestation (1.3%), and unknown gestation (1.4%). Additionally, we excluded records of multiple births (5.4%) and stillbirths (8.3%) leaving 4,691 records of singleton live-births for analysis. Logistic regression analysis was performed comparing preterm birth (22-36 weeks gestation) to term birth (37-41 weeks gestation). Multiple variable models adjusting for maternal age, parity, fetal position, delivery method and booking status were also evaluated. Multinomial regression was used to identify characteristics associated with preterm birth (PTB) defined as early PTB (22-31 weeks gestation), moderate PTB (32-34 weeks gestation), late PTB (35-36 weeks gestation), compared to term birth (37-41 completed weeks gestation).

Results

From our data, 16.8% of the singleton live-birth deliveries were preterm (<37 weeks gestation). Of these, 4.7% were early (22-31 weeks), 4.5% were moderate (32-34 weeks) and 7.7% were late (35-36) PTBs. Older maternal age (≥35 years) [odds ratio (OR) = 1.41], hypertension (OR = 3.44) and rupture of membranes (OR = 4.03) were significantly associated with increased odds of PTB. Women being treated for the prevention of mother-to-child transmission of HIV were at a significantly decreased risk for PTB (OR = 0.70). Sixteen percent of women in this cohort were not registered for antenatal care in LUTH. These non-registered subjects had significantly greater odds of all categories of PTB, including early (odds ratio (OR) = 20.8), moderate (OR = 8.68), and late (OR = 2.15).

Conclusion

PTB and risks for PTB remain high in Nigeria. We recommend that any high risk pregnancy should be referred to a tertiary center for prenatal care in order to significantly reduce adverse birth outcomes such as PTBs.

Effect of Young Maternal Age on Obstetric and Perinatal Outcomes: Results from the Tertiary Center in Turkey

BACKGROUND

Young maternal age is variously defined in studies of its effect on obstetrics and perinatal outcomes. Also, pregnancy has been reported as the leading cause of death in adolescent girls in low- and middle-income countries.

AIMS

The aim of the study was to evaluate whether young maternal age was associated with an increased risk of obstetrics and perinatal adverse outcomes.

STUDY DESIGN

Case-control study.

METHODS

This case-control study was derived from a database of the medical records between January 2008 and December 2012. In the present study, 1374 teenage pregnancy and 1294 adult pregnancy cases were included. After restriction of analyses to singleton primiparous women, 1282 teenage pregnancy and 735 adult pregnancy cases were analyzed. Maternal age was separated into three groups: 15 and less, 16-19, and 20-34 years. Adjusted odds ratios (ORs) were derived through logistic regression models for the potential confounding factors.

RESULTS

Adolescents aged 15 years and younger had higher risks of preterm delivery, early preterm delivery, intrauterine fetal death and neonatal death compared with women aged 20 to 34 years after adjustment for confounding factors. In addition, both groups of adolescents had higher risks for anemia and episiotomy and lower risk of cesarean delivery. The rates of preeclampsia, gestational diabetes, chronic diseases, intrauterine growth restriction (IUGR) were higher in the adult group.

CONCLUSION

Younger maternal age was correlated with increased risks of preterm delivery, fetal and neonatal death and anemia.

Adverse obstetrical and perinatal outcome in adolescent mothers associated with first birth: a hospital-based case-control study in a tertiary care hospital in North-East India

PURPOSE

To analyze the adverse obstetrical and perinatal outcome of adolescent mothers associated with first birth.

PATIENTS AND METHODS

This prospective case-control study was conducted in a tertiary care teaching hospital of North-East India between January 2014 and December 2014. All adolescent primigravidae completing 28 weeks of gestation with singleton pregnancy and delivered at our institution were included in the study group. Primigravidae aged between 20 and 25 years were taken as a control group. Mothers having pregnancy complicated with diabetes mellitus, renal disorder, thyroid disorders, and cardiac diseases were excluded from the study. Demographic data, maternal complications like severe anemia, pre-eclampsia, eclampsia, gestational age at delivery, mode of delivery, and postpartum complications were compared. Among fetal complications, low-birth weight, preterm birth, neonatal intensive care unit admission, still birth, and early neonatal death were compared. All the patients were interviewed regarding contraceptive knowledge and its use preceding the pregnancy.

RESULTS

Quality antenatal care was received by 80.6% of adolescent mothers. The adolescent mothers had a higher incidence of pre-eclampsia (odds ratio [OR] 2.017 95% confidence interval [CI]: 1.045-3.894, P=0.03), preterm deliveries (OR: 1.655, 95% CI: 1.039-2.636, P=0.03). Among fetal outcomes, the low- birth weight babies (OR: 1.59, 95% CI: 1.016-2.478), low mean birth weight (2,544.4±622.09 g versus 2,701.6±582.51 g), and higher admission to neonatal intensive care unit (OR: 1.957, 95% CI: 1.120-3.417) were significantly associated with adolescent mothers. There was no significant difference found regarding the mode of delivery, still birth, and early neonatal death. Moreover, contraceptive knowledge and its use were found to be poor among adolescent mothers.

CONCLUSION

With quality antenatal, intranatal, and postnatal care, the obstetric risk of childbirth in adolescent mothers may not be as serious as perceived to be.

Reducing health inequalities among girls and adolescent women living in poverty: the success of Bangladesh

BACKGROUND

Bangladesh has made dramatic improvements in the health of girls and women in the last 20 years. This paper examines whether gender inequalities in health are evident among older children and adolescents among extremely poor households and identifies future health challenges for improving the health of girls and women.

SUBJECTS AND METHODS

Gender inequalities in health were examined using data from a school health survey of school children and adolescents (n = 900, 6.5-13.5 years). Anthropometric status, household possessions and number of siblings were measured. Under-nutrition was assessed as stunting (height-for-age z-score) and thinness (BMI-for-age z-score).

RESULTS

The prevalence of under-nutrition was high (35.3% stunting; 42.4% thinness), but there were no significant differences according to gender or socio-economic indicators (via possession score). Girls had more younger siblings (p < 0.05), while boys had more older siblings (p < 0.05).

CONCLUSIONS

These findings accord with the national picture of successful reductions in gender inequalities in health through low cost, community-based health programmes and education policies targeting the poorest sectors. The prevalence of under-nutrition, however, remains high. Reproductive behaviours may still be influenced by poverty and the gender of existing offspring. Future challenges lie in reducing the adverse health consequences to women and their infants associated with early age at marriage and childbirth.

The Effect of Adequate Gestational Weight Gain among Adolescents Relative to Adults of Equivalent Body Mass Index and the Risk of Preterm Birth, Cesarean Delivery, and Low Birth Weight

OBJECTIVE

To determine whether similar odds of cesarean delivery (C/S), preterm birth (PTB), and low birth weight (LBW) are observed among adolescents compared with body mass index (BMI)-equivalent adults in cases of adequate gestational weight gain.

STUDY DESIGN

We conducted a retrospective, population-based, cohort study using the Center for Disease Control and Prevention's birth data files from the United States for 2012. We selected from the cohort all singleton, cephalic pregnancies and stratified them according to maternal age, prepregnancy BMI, and gestational weight gain following the 2009 Institute of Medicine (IOM) recommendations. The effect of adequate gestational weight gain among adolescents relative to adults of equivalent BMI on the risk of C/S, PTB, and LBW was estimated using logistic regression analysis, adjusting for relevant confounders.

RESULTS

We analyzed a total of 3,960,796 births, of which 1,036,646 (26.1%) met the inclusion criteria. In adolescents and adults, likelihood of achieving ideal gestational weight gain decreased with greater prepregnancy BMI. Relative to adults, the overall odds of C/S in all adolescents were (adjusted odds ratio [95% confidence interval]) 0.61 (0.58 to 0.63). When comparing equivalent BMI categories, these odds were unchanged (P < .0001). The overall adjusted odds ratio of LBW was 1.15 (1.13 to 1.16). These odds were significantly higher when BMI stratification took place, decreasing with advancing BMI categories, from 1.23 (1.14 to 1.33) among the underweight, to nonsignificant differences in the obese classes (P < .05). Finally, when including only those achieving ideal weight gain, the overall odds of premature delivery (1.17 [1.14 to 1.20]) were higher among nonobese adolescents, while they were not found among the obese.

CONCLUSION

When ideal gestational weight gain is attained, only nonobese adolescents exhibit a greater risk of LBW and preterm birth relative to adults of similar BMI, whereas the risk of C/S remains lower for all adolescents, independent of BMI. This information may be useful in the counseling of adolescent pregnancies.

A meta-analysis of socio-demographic factors for perinatal mortality in developing countries: a subgroup analysis of the national surveys and small scale studies

BACKGROUND

Although the perinatal mortality in low income countries is about five-folds higher than in the high income countries, little is known about the association of socio-demographic factors with perinatal mortality. National and small scale studies so far reported have shown very contradictory results. The objective of this meta-analysis was to assess the association of perinatal mortality with selected sociodemographic factors.

METHODS

A computer based literature search was conducted mainly in the databases of African Journals Online, MEASURE Demographic and Health Survey (DHS), Google Scholar, HINARI, PUBMED, MEDLINE and the Cochrane Library. The inclusion criteria were: 1) studies that assessed the perinatal mortality in developing countries in relation to socio-demographic predictors and 2) studies published in English and conducted after the year 1990. Subgroup meta-analyses of perinatal mortality were performed for mothers' age, residence, educational level and wealth status. Sensitivity analysis and heterogeneity testing were done.

RESULTS

In this meta-analysis, several inconsistent associations of perinatal mortality with the selected socio-demographic variables were observed in the primary studies level, both DHS and small scale studies. However, the overall odds ratio (OR) demonstrated statistically significant association of perinatal mortality with low maternal age (OR=1.2) and short birth interval (OR=1.4) but was not influenced by the mothers' residence, low educational level and household wealth index. Very consistently, the highest perinatal mortality rates reported when the birth intervals were either too short (<15 months) or too long (>39 months).

CONCLUSION

Because of the disagreement among previous studies, the present study demonstrated a small effect size on the increased risk of perinatal mortality among women who were pregnant during teenage ages and gave birth too frequently or after a long interval. Therefore, to confirm the strong predictors of perinatal mortality, further studies on sociodemographic factors are needed.

Adverse maternal and perinatal outcomes in adolescent pregnancies: The Global Network's Maternal Newborn Health Registry study

BACKGROUND

Adolescent girls between 15 and 19 years give birth to around 16 million babies each year, around 11% of births worldwide. We sought to determine whether adolescent mothers are at higher risk of maternal and perinatal adverse outcomes compared with mothers aged 20-24 years in a prospective, population-based observational study of newborn outcomes in low resource settings.

METHODS

We undertook a prospective, population-based multi-country research study of all pregnant women in defined geographic areas across 7 sites in six low-middle income countries (Kenya, Zambia, India, Pakistan, Guatemala and Argentina). The study population for this analysis was restricted to women aged 24 years or less, who gave birth to infants of at least 20 weeks' gestation and 500g or more. We compared adverse pregnancy maternal and perinatal outcomes among pregnant adolescents 15-19 years, <15 years, and adults 20-24 years.

RESULTS

A total of 269,273 women were enrolled from January 2010 to December 2013. Of all pregnancies 11.9% (32,097/269,273) were in adolescents 15-19 years, while 0.14% (370/269,273) occurred among girls <15 years. Pregnancy among adolescents 15-19 years ranged from 2% in Pakistan to 26% in Argentina, and adolescent pregnancies <15 year were only observed in sub-Saharan Africa and Latin America. Compared to adults, adolescents did not show increased risk of maternal adverse outcomes. Risks of preterm birth and LBW were significantly higher among both early and older adolescents, with the highest risks observed in the <15 years group. Neonatal and perinatal mortality followed a similar trend in sub-Saharan Africa and Latin America, with the highest risk in early adolescents, although the differences in this age group were not significant. However, in South Asia the risks of neonatal and perinatal death were not different among adolescents 15-19 years compared to adults.

CONCLUSIONS

This study suggests that pregnancy among adolescents is not associated with worse maternal outcomes, but is associated with worse perinatal outcomes, particularly in younger adolescents. However, this may not be the case in regions like South Asia where there are decreasing rates of adolescent pregnancies, concentrated among older adolescents. The increased risks observed among adolescents seems more likely to be associated with biological immaturity, than with socio-economic factors, inadequate antenatal or delivery care.

Trends in and socio-demographic factors associated with caesarean section at a Tanzanian referral hospital, 2000 to 2013

BACKGROUND

Caesarean section (CS) can prevent maternal or fetal complications. Sub-Saharan Africa has the lowest CS levels in the world but large variations are seen between and within countries. The tertiary hospital, Kilimanjaro Christian Medical Centre (KCMC) in Tanzania has had a high level of CS over years. The aim of this study was to examine trends in the socio-demographic background of babies born at KCMC from year 2000 to 2013, and trends in the CS percentage, and to identify socio-demographic factors associated with CS at KCMC during this period.

METHODS

This is a registry-based study. The analyses were limited to singletons born by women from Moshi urban and rural districts. The Chi square test for linear trend was used to examine trends in the CS percentage and trends in the socio-demographic background of the baby. The association between different socio-demographic factors and CS was assessed using logistic regression. The analyses were stratified by the mother's residence.

RESULTS

The educational level of mothers and fathers and the age of the mothers of singletons born at KCMC increased significantly from year 2000 to 2013 both among urban and rural residents. Among 29,752 singletons, the overall CS percentage was 28.9%, and there was no clear trend in the overall CS percentage between 2000 and 2013. In the multivariable model, factors associated with higher odds of CS were: having been referred for delivery, maternal age above 25 and no- or primary education level of the baby's father. Among rural mothers, no- or primary education, being from the Pare tribe and para 2-3 were also associated with higher odds of CS. Being from the Chagga tribe and high parity were associated with lower odds of CS compared to other tribes and parity 1.

CONCLUSIONS

The CS percentage remained high but stable over time. Large variations in CS levels between different socio-demographic groups were observed. The educational level of the parents of babies born at KCMC increased over time, possibly reflecting persistent inequitable access to the services offered at the hospital.

Pregnancy and childbirth outcomes among adolescent mothers: a World Health Organization multicountry study

OBJECTIVE

To investigate the risk of adverse pregnancy outcomes among adolescents in 29 countries.

DESIGN

Secondary analysis using facility-based cross-sectional data of the World Health Organization Multicountry Survey on Maternal and Newborn Health.

SETTING

Twenty-nine countries in Africa, Latin America, Asia and the Middle East.

POPULATION

Women admitted for delivery in 359 health facilities during 2-4 months between 2010 and 2011.

METHODS

Multilevel logistic regression models were used to estimate the association between young maternal age and adverse pregnancy outcomes.

MAIN OUTCOME MEASURES

Risk of adverse pregnancy outcomes among adolescent mothers.

RESULTS

A total of 124 446 mothers aged ≤24 years and their infants were analysed. Compared with mothers aged 20-24 years, adolescent mothers aged 10-19 years had higher risks of eclampsia, puerperal endometritis, systemic infections, low birthweight, preterm delivery and severe neonatal conditions. The increased risk of intra-hospital early neonatal death among infants born to adolescent mothers was reduced and statistically insignificant after adjustment for gestational age and birthweight, in addition to maternal characteristics, mode of delivery and congenital malformation. The coverage of prophylactic uterotonics, prophylactic antibiotics for caesarean section and antenatal corticosteroids for preterm delivery at 26-34 weeks was significantly lower among adolescent mothers.

CONCLUSIONS

Adolescent pregnancy was associated with higher risks of adverse pregnancy outcomes. Pregnancy prevention strategies and the improvement of healthcare interventions are crucial to reduce adverse pregnancy outcomes among adolescent women in low- and middle-income countries.
