Socioeconomic and residence-based inequalities in adolescent fertility in 39 African countries.

INTRODUCTION: Despite the advancement in sexual and reproductive healthcare services and several public health measures aimed at controlling fertility rates, countries in sub-Saharan Africa (SSA) still experience higher adolescent fertility rates than other low-and middle-income countries. This study examined the disparities in adolescent fertility in 39 countries in SSA, focusing on socioeconomic and residence-based dimensions. METHODS: This study involved a secondary analysis of data obtained from 39 recent Demographic and Health Surveys conducted in SSA. The measures of difference (D), ratio (R), population attributable fraction (PAF), and population attributable risk (PAR) were estimated using the Health Equity Assessment Tool (HEAT) software version 3.1 developed by the World Health Organization. The measures: D, R, PAF, and PAR were used to examine the inequalities in adolescent fertility across the socioeconomic and residence-based dimensions. RESULTS: Out of the 39 countries included in the study, Guinea (D=27.70), Niger (D=27.50), Nigeria (D=23.90), and Côte d'Ivoire (D=23.60) exhibited the most significant residence-based inequalities in the rate of adolescent fertility, with the higher rate observed among adolescents in rural areas. Rwanda was the sole country that showed a slight inclination towards rural inequality in terms of the rate of adolescent fertility, with a value of D = -0.80. The burden of adolescent fertility was disproportionately higher among young women with low economic status across all the countries, exacerbating wealth-based inequities. The countries with the largest absolute discrepancies were Nigeria (D=44.70), Madagascar (D=41.10), Guinea (D=41.00), and Cameroon (D=40.20). We found significant disparities in educational attainment contributing to unequal inequalities in adolescent fertility, particularly among young women who lack access to formal education. Countries such as Madagascar (D=59.50), Chad (D=55.30), Cameroon (D=54.60), and Zimbabwe (D=50.30) had the most significant absolute disparities. CONCLUSION: This study revealed that young women residing in rural areas, those in households with low economic status and those with limited educational opportunities experience a disproportionately high burden of adolescent fertility across the 39 countries in SSA. The current findings offer valuable information to governmental entities at all levels regarding the need to ensure the provision of equitable, accessible, and dependable sexual and reproductive health services to the populace, particularly for young women. Therefore, the various stakeholders need to enhance the effectiveness of health policies and legislation pertaining to adolescent women living in rural areas, those from economically disadvantaged households, and those with limited or no access to formal education. Such interventions could potentially reduce adolescent fertility rates and mitigate the adverse maternal and child outcomes associated with high adolescent fertility in SSA.

Adolescent fertility is a major health problem for many developing countries, especially those in sub-Saharan Africa (SSA). Although several sexual and reproductive health initiatives have been introduced in these countries, the number of births among adolescents continues to be high. The present study looked at the socioeconomic and geographical differences in adolescent fertility across 39 countries in SSA using data from the Demographic and Health Surveys embedded into the World Health Organization's Health Equity Assessment Toolkit (WHO HEAT) software. The study found that in countries like Guinea, Niger, Nigeria, and Côte d'Ivoire, the rates of adolescent fertility varied a lot, with higher rates in rural areas. Generally, poorer young women were more likely to have babies, which made the gap between the rich and the poor even wider. Nigeria, Madagascar, Guinea, and Cameroon had the biggest differences. Education also played a role. In countries like Madagascar, Chad, Cameroon, and Zimbabwe, young women who did not go to school (had no education) were more likely to have children as teenagers.  The study showed that in all 39 countries, young women living in rural areas, those who were poorer and those who did not go to school (had no education) faced a bigger problem with adolescent fertility. The study suggests that if people who make health policies pay more attention to teenage girls in the rural areas, those who are poor and do not have much education, they could make a significant difference in reducing adolescent fertility.

What's Behind the Dramatic Pre-2020 Declines in Hispanic/Latina Adolescent Childbearing? Decomposing Change by Age, Origin, and Nativity.

PURPOSE: To assess whether the large declines in adolescent childbearing among Hispanic adolescents over the period 2000-2019 have been driven by co-occurring changes in the composition of the Hispanic population and, if so, whether they have done so differentially by Hispanic subgroup. METHODS: We use birth counts from the United States vital statistics system and population denominators from the United States decennial census long form 5-percent Public Use Microdata and the American Community Survey to conduct a decomposition analysis apportioning observed declines in Hispanic adolescent childbearing to: (1) compositional shifts in nativity, age, and region-of-origin and (2) subgroup changes in childbearing rates. RESULTS: The Hispanic adolescent fertility rate fell by over 71% from 2000 to 2019, with Mexican-Origin, United States-born, and younger adolescents exhibiting the steepest declines (79%, 70%, and 80% declines, respectively). Results from the decomposition analysis show that almost 90% of the decline is due to within-group rate change, with some variability by subgroup and by decade. Only 10% of the decline was due to compositional changes, with shifts in nativity driving much of the effect. DISCUSSION: Declines in Hispanic adolescent childbearing over the last decades have occurred in spite of substantial shifts in the composition of the Hispanic population, not because of them. These findings set the stage for a more detailed examination of the drivers of change in sexual activity, contraceptive use, and abortion, all of which are proximate determinants of adolescent pregnancy and childbearing. Additionally, a focus on more distal factors is needed, including the role that changing political, societal, and economic conditions in the United States have for early fertility patterns.

Access to Higher Education and Adolescent Fertility in Chile.

This study investigates gender differences in the association between adolescent fertility and the likelihood of initiating higher education among young Chilean men and women. We adopt an entropy balancing strategy to estimate the association between adolescent fertility and the likelihood of starting higher education while accounting for potential selection into early childbearing due to socioeconomic status and prior academic achievement. We use data from official national registers that cover a cohort of Chilean students who attended publicly funded schools and who successfully completed secondary schooling between 2011 and 2022. Our results indicate that adolescent mothers are 15 percentage points less likely to initiate higher education than their peers who did not give birth during adolescence. In comparison, teenage fathers are 20 percentage points less likely to do so than their childless counterparts. Our findings stand in contrast to previously identified disadvantage patterns for secondary school completion, whereby adolescent fertility more significantly hinders schooling completion for women relative to men. We contend that this reversal may be related to traditional gender-role expectations in Chile, which encourage young fathers to act as providers and, therefore, may be prevented from continuing on their education path into tertiary studies.

Effects of the reaching married adolescents program on modern contraceptive use and intimate partner violence: results of a cluster randomized controlled trial among married adolescent girls and their husbands in Dosso, Niger.

BACKGROUND: Niger has the highest rate of adolescent fertility in the world, with early marriage, early childbearing and high gender inequity. This study assesses the impact of Reaching Married Adolescents (RMA), a gender-synchronized social behavioral intervention designed to improve modern contraceptive use and reduce intimate partner violence (IPV) among married adolescent couples in rural Niger. METHODS: We conducted a four-armed cluster-randomized trial in 48 villages across three districts in Dosso region, Niger. Married adolescent girls (ages 13-19) and their husbands were recruited within selected villages. Intervention arms included home visits by gender-matched community health workers (CHWs) (Arm 1), gender-segregated, group discussion sessions (Arm 2), and both approaches (Arm 3). We used multilevel mixed-effects Poisson regression models to assess intervention effects for our primary outcome, current modern contraceptive use, and our secondary outcome, past year IPV. RESULTS: Baseline and 24-month follow-up data were collected April-June 2016 and April-June 2018. At baseline, 1072 adolescent wives were interviewed (88% participation), with 90% retention at follow-up; 1080 husbands were interviewed (88% participation), with 72% retention at follow-up. Adolescent wives had higher likelihood of modern contraceptive use at follow-up relative to controls in Arm 1 (aIRR 3.65, 95% CI 1.41-8.78) and Arm 3 (aIRR 2.99, 95% CI 1.68-5.32); no Arm 2 effects were observed. Relative to those in the control arm, Arm 2 and Arm 3 participants were significantly less likely to report past year IPV (aIRR 0.40, 95% CI 0.18-0.88 for Arm 2; aIRR 0.46, 95% CI 0.21-1.01 for Arm 3). No Arm 1 effects were observed. CONCLUSIONS: The RMA approach blending home visits by CHWs and gender-segregated group discussion sessions is the optimal format for increasing modern contraceptive use and decreasing IPV among married adolescents in Niger. Trial registration This trial is retrospectively registered with ClinicalTrials.gov, Identifier NCT03226730.

Although Niger has both the highest levels of fertility and of child marriage in the world, as well as substantial gender inequity, there have been no high-quality evaluations of public health programs aiming to increase contraceptive use or decrease intimate partner violence. In this study, we conducted a high quality, randomized controlled trial to evaluate whether the Reaching Married Adolescents public health program could increase modern contraceptive use and decrease intimate partner violence among married adolescent girls (13­19 years old) and their husbands in the Dosso region of Niger. The results of this evaluation provide evidence of the value of individual home visits for wives and their husbands in increasing modern contraceptive use, the value of small group discussions in reducing intimate partner violence, and the combined value of receiving both approaches at the same time for both increasing modern contraceptive use and decreasing intimate partner violence. The current study advances the state of evidence regarding contraceptive use and IPV among married adolescents and their husbands in Niger, highlighting the importance of engaging male partners in such public health programs, as well as of using multiple modes of delivery of programs. The success of this intervention in the high-risk context of Niger suggests that other countries in the region may benefit from testing this approach to improve the health and well-being of young wives.

Adolescent fertility in Cuba is high and shows resistance to its reduction in recent years despite the actions taken. To promote responsible sexuality in adolescents, a different and particular action of pediatricians is required. The objective of this collaboration is to provide elements that sensitize and involve Cuban pediatricians to offer guidance to adolescents on the exercise of a full, free and responsible sexuality, which contributes to the reduction of fertility and comprehensive care of sexual and reproductive health. The method used was the review of current legislation and the recommendations of several international pediatric societies, regarding the role and importance of the specialty in the prevention of adolescent pregnancy. The advantages of the pediatrician for the prevention of adolescent fertility are highlighted, the skills they must acquire to inform and guide adolescents are explained, the barriers that the pediatrician must face to favor the access of adolescents to prevent fertility are analyzed, and the specific recommendations for the action of the pediatrician in the prevention of adolescent fertility are exposed. It is concluded that Cuban pediatricians can contribute to the reduction of fertility and improve the comprehensive care of sexual and reproductive health of adolescents(AU)

La fecundidad en Argentina a inicios del siglo XXI: ¿el fin de la meseta? El papel de la educación en los cambios / Fecundidade na Argentina no início do século 21: o fim do plateau? Efeitos da educação nas mudanças / Fertility in Argentina at the beginning of the 21st century: the end of the plateau? Effects of education on changes

Resumen El presente trabajo ofrece un análisis del comportamiento de la fecundidad desagregado por nivel de instrucción de la madre en Argentina en el siglo XXI y presta especial atención a la evolución de la fecundidad adolescente en el mismo período. A diferencia de lo acontecido en otros países de la región en las últimas dos décadas, donde el descenso de la fecundidad fue casi ininterrumpida, en la Argentina la fecundidad tuvo un comportamiento estable, similar a una meseta, desde comienzos del siglo XXI hasta 2014, a partir de cuando comenzó un descenso sostenido análogo al de sus países vecinos. Para este análisis se usan datos de las estadísticas vitales y de las estimaciones y proyecciones de población del INDEC, y para el análisis por nivel de instrucción, datos de las encuestas permanentes de hogares del INDEC y del Censo Nacional de Población y Vivienda de 2010. En el análisis se puede observar una importante brecha en los niveles de fecundidad entre las mujeres más y menos instruidas, principalmente en la fecundidad adolescente. Esta brecha es un reflejo de inequidad, dado que la alta fecundidad afecta sobre todo a las mujeres de los estratos sociales más vulnerables.

Resumo Este documento faz uma análise do comportamento da fecundidade na Argentina no século 21, desagregado por nível de escolaridade da mãe, com especial atenção à evolução da fecundidade na adolescência nesse período. Ao contrário do que aconteceu em outros países da região nas últimas duas décadas, onde a fecundidade diminuiu quase continuamente, na Argentina a fecundidade teve um comportamento estável, semelhante a um plateau, desde o início do século 21 até 2014, quando começou um declínio sustentado semelhante ao observado nos países vizinhos. Utilizamos dados de estatísticas vitais, estimativas e projeções da população do INDEC e, para a análise por nível de educação, dados das Pesquisas Domésticas do INDEC e do Censo Nacional da População e Habitação 2010. A análise mostra uma lacuna significativa nos níveis de fecundidade entre as mulheres mais e menos instruídas, principalmente na fecundidade adolescente. Esta lacuna é reflexo da desigualdade, uma vez que a alta fecundidade afeta principalmente as mulheres dos estratos sociais mais vulneráveis.

Abstract This paper presents an analysis of Argentina's fertility behavior disaggregated by level of education of the mother in the 21st century, and focuses on the evolution of adolescent fertility during the same period. Unlike what other countries from the region have experienced in the last two decades, where fertility decline occurred almost uninterruptedly, Argentina's fertility had a stable behavior, similar to a plateau, from the beginning of the 21st century until 2014. Since then, it began a sustained decline similar to that evidenced in neighboring countries. Data from vital statistics, INDEC population estimates and projections are used, and data from INDEC Household Surveys and the 2010 National Population and Housing Census are used for the analysis by education level. The analysis shows a significant gap in fertility levels between the most and least educated women, mainly in adolescent fertility. This gap is a reflection of inequity, given that high fertility rates mainly affect women from the most vulnerable social strata.

Association between socioeconomic status and fertility among adolescents aged 15 to 19: an analysis of the 2013/2014 Zambia Demographic Health Survey (ZDHS).

BACKGROUND: Adolescents face significant barriers to access and utilization of sexual and reproductive health services in many low-income settings, which in turn may be associated with adverse consequences such as early pregnancy, sexually transmitted infections, unsafe abortion and mortality. There is evidence suggesting that limited access to sexual and reproductive health information and services among adolescents contributes to these outcomes. We aimed to find out the factors that affect the fertility of adolescents aged 15 to 19 years in Zambia and to identify possible drivers of adolescents' fertility. METHODS: Secondary analysis of the ZDHS 2013/14 data was carried out to find out the factors that affect the fertility rate of adolescents aged 15 to 19 years using multivariate logistic regression (n = 3666). RESULTS: Overall, 23.1% of adolescents had given birth at least once in the 5 years leading to the survey (n = 3666, 99.4% response), and 49.8% were rural-based while 50.2% were urban-based. The median number of schooling was 8 years (IQR 6-10). About 52% of the adolescents were in the poorer, poor and medium wealth quintiles while the other 48% were in the rich and richer quintiles. Factors found to affect fertility include residence, wealth status, educational attainment, marriage and abortion. An urban-based adolescent with a lower socioeconomic status was 2.4 times more likely to give birth compared to rural-based poorer adolescents (aOR = 2.4, 95% CI: 1.5, 3.7, p < 0.001). Although odds of giving birth were much higher among rural-based married adolescents (aOR = 8.0, 95% CI: 5.4, 11.9, p < 0.001) compared to urban married adolescents (aOR = 5.5, 95% CI: 8.3, 16.0, p < 0.001), and these relationships both statistically significant, higher educational attainment (aOR = 0.7, 95% CI: 0.6, 0.8 p < 0.001) and abortion (aOR = 0.3, 95% CI: 0.1, 0.8, p = 0.020) reduced these odds, particularly for rural-based adolescents. CONCLUSION: Despite response aimed at reducing adolescent fertility, low wealth status, low educational attainment and early marriage remain significant drivers of adolescent fertility in Zambia. There is a need to address sexual and reproductive health needs of urban-based adolescents with a lower socioeconomic status.

Adolescents go through serious challenges related to accessing and using sexual and reproductive health services in many low-income settings, and may also be related to negative consequences such as early pregnancy, sexually transmitted infections and unsafe abortion and death. Research has revealed that limited access to sexual and reproductive health information and services among young people contributes to these negative consequences. This analysis aimed to find out the factors that affect the fertility of 3666 adolescents aged 15 to 19 years in Zambia and to identify possible drivers of adolescents' fertility, using the Zambia Demographic and Health Survey conducted in 2013/2014. A little over a quarter of the adolescents had given birth at least once in the five years leading to the survey. About half of the young people were rural-basedwhile the other half were urban-based, with an average of about 8 years in school. The rural-based adolescents had slightly lower average years in school compared to the urban-based; 7 years and 9 years respectively. Living in a rural area, residing in a home with a low wealth status and being married were all linked to higher chances of giving birth, while terminating a pregnancy and having more years of education were linked to lower chances of giving birth among the adolescents. Urban-based adolescents with lower wealth status were also linked to higher chances of giving birth compared to urban-based adolescents with higher wealth status. These results suggest that while residing in rural areas and being married increase the chances of higher fertility, the adolescents in urban areas but with lower wealth status also need interventions aimed at reducing their fertility.

Birth Collapse and a Large-Scale Access Intervention with Subdermal Contraceptive Implants.

Between 2016 and 2018, we observe in Uruguay a steep decline of almost 20 percent in the number of total births, leading to the collapse of the adolescent fertility rate after decades of relative stagnation. We estimate the quantitative contribution on birth rates, especially teen births, of a policy of expanded availability of subdermal contraceptive implants. We exploit the expansion schedule of a large-scale policy of free-of-charge access to subdermal implants in the country's public health system through an event study to capture causal effects. We use detailed birth administrative records for the past 20 years. We document an average reduction of 3 percent in the birth rate in public health facilities across the two years after the policy was implemented in each department. These reductions were notably higher among teens and first births. Although changes in women's fertility decisions are a multicausal phenomenon, we claim that the expanded availability of subdermal contraceptive implants accounted for one-third of the teen and young women's birth collapse.

Socio-economic and geographical inequalities in adolescent fertility rate in Ghana, 1993-2014.

BACKGROUND: Despite public health interventions to control adolescent fertility, it remains high in sub-Saharan Africa. Ghana is one of the countries in sub-Saharan Africa with the highest adolescent fertility rates. We examined the trends and socio-economic and geographical patterns of disparities in adolescent fertility in Ghana from 1993 to 2014. METHODS: Using the World Health Organization's (WHO) Health Equity Assessment Toolkit (HEAT) software, data from the 1993-2014 Ghana Demographic and Health surveys were analyzed. First, we disaggregated adolescent fertility rates (AFR) by four equity stratifiers: wealth index, education, residence and region. Second, we measured the inequality through summary measures, namely Difference (D), Population Attributable Risk (PAR), Ratio (R) and Population Attributable Fraction (PAF). A 95 % confidence interval was constructed for point estimates to measure statistical significance. RESULTS: We observed substantial absolute and relative wealth-driven inequality in AFR (PAR=-47.18, 95 % CI; -49.24, -45.13) and (PAF= -64.39, 95 % CI; -67.19, -61.59) respectively in favour of the economically advantaged subpopulations. We found significant absolute (D = 69.56, 95 % CI; 33.85, 105.27) and relative (R = 3.67, 95 % CI; 0.95, 6.39) education-based inequality in AFR, with higher burden of AFR among disadvantaged subpopulations (no formal education). The Ratio measure (R = 2.00, 95 % CI; 1.53, 2.47) indicates huge relative pro-urban disparities in AFR with over time increasing pattern. Our results also show absolute (D, PAR) and relative (R, PAF) inequality in AFR across subnational region, between 2003 and 2014. For example, in the 2014 survey, the PAR measure (D=-28.22, 95 % CI; -30.58, -25.86) and the PAF measure (PAF=-38.51, 95 % CI; -41.73, -35.29) indicate substantial absolute and relative regional inequality. CONCLUSIONS: This study has indicated the existence of inequality in adolescent fertility rate in Ghana, with higher ferlitiy rates among adolescent girls who are poor, uneducated, rural residents and those living in regions such as Northern, Brong Ahafo, and Central region, with increasing disparity over the time period of the study. There is the need for policy interventions that target adolescent girls residing in the rural areas and those in the low socioeconomic subgroups to enable the country to avert the high maternal/newborn morbidity and mortality usually associated with adolescent childbearing.

Summary measures of socioeconomic and area-based inequalities in fertility rates among adolescents: evidence from Ethiopian demographic and health surveys 2000-2016.

BACKGROUND: One of the highest rates of adolescent pregnancies in the world is in sub-Saharan Africa. Most adolescent pregnancies in the region are unintended or unwanted, due to poor access to information and services on sexual and reproductive health for adolescents. Ethiopia has high adolescent fertility rates (AFR) with disparities across socioeconomic subgroups and regions. This study assessed the magnitude and trends of socioeconomic and area-based AFR inequalities in Ethiopia. METHODS: The 2000 and 2016 Ethiopia Demographic and Health surveys (EDHS) was analyzed using the World Health Organization's (WHO) Health Equity Assessment Toolkit (HEAT) software. Adolescent fertility rates were disaggregated using three equity stratifiers (economic status, education and residence) and analyzed through four summary measures (Difference (D), Population Attributable Risk (PAR), Ratio (R) and Population Attributable Fraction (PAF)) to assess inequality. To measure statistical significance, point estimates were constructed using a 95% Uncertainty Interval (UI). RESULTS: Large socio-economic and urban-rural inequalities were observed within the 16-year period. Adolescents in less well-off socio-economic groups (PAF: -62.9 [95% UI; - 64.3, - 61.4], D: 96.4 [95% UI; 47.7, 145.1]), uneducated (R: 8.5 [95% UI; 4.8, 12.2], PAR: -76.4 [95% UI;-77.7, - 75.0]) and those from rural areas (D: 81.2 [95% UI; 67.9, 94.6], PAF: -74.2 [95% UI, - 75.7, - 72.7]) had a higher chance of pregnancy and more births than their counterparts. CONCLUSIONS: Socioeconomic (education and economic status) and place of residence determine adolescents' pregnancy and childbearing. Policies and programs should be directed at preventing child marriage and early fertility so that adolescents continue to access education, sexual and reproductive health care as well as access employment opportunities. More emphasis should be placed on subpopulations with disproportionately higher adolescent pregnancy and childbirth.

A critical discourse analysis of adolescent fertility in Zambia: a postcolonial perspective.

BACKGROUND: Despite global and regional policies that promote the reduction of adolescent fertility through ending early marriages and reducing early child-bearing, adolescent fertility remains high in most sub-Saharan countries. This study aimed to explore the competing discourses that shape adolescent fertility control in Zambia. METHODS: A qualitative case study design was adopted, involving 33 individual interviews and 9 focus group discussions with adolescents and other key-informants such as parents, teachers and policymakers. Thematic and critical discourse analysis were used to analyze the data. RESULTS: Adolescents' age significantly reduced their access to Sexual and Reproductive Health, SRH services. Also, adolescent fertility discussions were influenced by marital norms and Christian beliefs, as well as health and rights values. While early marriage or child-bearing was discouraged, married adolescents and adolescents who had given birth before faced fewer challenges when accessing SRH information and services compared to their unmarried or nulliparous counterparts. Besides, the major influencers such as parents, teachers and health workers were also conflicted about how to package SRH information to young people, due to their varying roles in the community. CONCLUSION: The pluralistic view of adolescent fertility is fueled by "multiple consciousnesses". This is evidenced by the divergent discourses that shape adolescent fertility control in Zambia, compounded by the disempowered position of adolescents in their communities. We assert that the competing moral worlds, correct in their own right, viewed within the historical and social context unearth significant barriers to the success of interventions targeted towards adolescents' fertility control in Zambia, thereby propagating the growing problem of high adolescent fertility. This suggests proactive consideration of these discourses when designing and implementing adolescent fertility interventions.

Gender differences in high-school dropout: Vulnerability and adolescent fertility in Chile.

The original concerns about the consequences of adolescent fertility assumed that pregnancy is a turning point, which altered teens' life trajectories in terms of school progress, human capital accumulation and labor force participation, placing them on a path of vulnerability. However, several years of research have shown that teenagers who become pregnant are not a random sample of the population, but a selective sample, more likely to have limited socioeconomic resources and other characteristics that made them a vulnerable group to begin with. This paper studies the association between adolescent fertility and high school dropout in Chile taking that selectivity in consideration. We analyze the dropout of teen men and women, considering their socioeconomic status, sociodemographic characteristics, and characteristics of their sexual debut. Data comes the VIII Chilean Survey of the Youth, a nationally representative survey of people 15-29 years old applied in 2015. In order to deal with selectivity issues, we use a combination of propensity score weighting techniques and adjusted generalized linear models for estimating the effect of teen parenthood on high school dropout (ATT), for men and women separately. Our best estimates of the effect of teen parenting on the probability of high school dropout is 16-18 percent for women and ten percent for men, which implies that the educational setback of parenthood for women is about twice as high as the setback of men. These findings suggest the need of policies and interventions aimed both to reduce adolescent fertility, but also to facilitate the high school completion of those who already are parents.

From science to sustainable systems: Evidence based-decision making for adolescent fertility in Zambia.

Adolescent fertility is a global health and sustainable development indicator, and requires robust information systems for priority setting and decision-making to control. Evidence-based decision making for health stresses the use of scientific objective data and methodologies, which typically sieve out the more contextually understood social and economic factors that impact health. Main Text: The rising adolescent fertility rates in Zambia warrant the use of robust information systems for planning and resource allocation. In addition to the shortage of information on adolescent health in general, the existing information systems are limited. Sustainable information systems require an investment in data collection that transcends the existing and heavily relied on quantitative evidence base on adolescent sexual and reproductive health, arguing for the need to include data generated through qualitative and participatory methodologies, generating a more holistic understanding of health phenomena. Conclusion: There is a need to collect data on adolescent fertility using alternative methods to make decisions that work for adolescents.

Unsafe abortion - A Risk factor for maternal mortality in Liberia - An analysis of the characteristics of unsafe abortion clients and risk factors for maternal morbidity and mortality.

Worldwide, an estimated 68,000 women die yearly due to unsafe abortion practices. In Liberia, the maternal mortality ratio is 1072 deaths per 100,000 live births. However, there has not been a study conducted to understand the relationship between unsafe abortion and maternal mortality. We conducted a retrospective cohort study at three county hospitals and assessed obstetric data gathered using a defined questionnaire in 2016 - 2018, from maternal-child health units. The results of the study suggest a strong association between unsafe abortion and maternal morbidity and mortality and also provide insight into the characteristics and factors that put women and girls who have unsafe abortions at risk. The results can inform programs and policies on age disaggregation of women and girls who choose abortion. The variation in the association between unsafe abortion and the risk factors, have implications for maternal morbidity and mortality.

Inequality in fertility rate among adolescents: evidence from Timor-Leste demographic and health surveys 2009-2016.

BACKGROUND: Despite a decline in global adolescent birth rate, many countries in South East Asia still experience a slower pace decline in adolescent birth rates. Timor-Leste is one of the countries in the region with the highest adolescent birth rate and huge disparities between socio-economic subgroups. Hence, this study assessed the magnitude and trends in adolescent fertility rates within different socio-demographic subgroups in Timor-Leste. METHODS: Using the World Health Organization's (WHO) Health Equity Assessment Toolkit (HEAT) software, data from the Timor-Leste Demographic and Health surveys (TLDHS) were analyzed between 2009 and 2016. We approached the inequality analysis in two steps. First, we disaggregated adolescent fertility rates by four equity stratifiers: wealth index, education, residence and region. Second, we measured the inequality through summary measures, namely Difference, Population Attributable Risk, Ratio and Population Attributable Fraction. A 95% confidence interval was constructed for point estimates to measure statistical significance. RESULTS: We found large socio-economic and area-based inequalities over the last 7 years. Adolescent girls who were poor (Population Attributable Fraction: -54.87, 95% CI; - 57.73, - 52.02; Population Attributable Risk: -24.25, 95% CI; - 25.51, - 22.99), uneducated (Difference: 58.69, 95% CI; 31.19, 86.18; Population Attributable Fraction: -25.83, 95% CI; - 26.93, - 24.74), from rural areas (Ratio: 2.76, 95% CI; 1.91, 3.60; Population Attributable Risk: -23.10, 95% CI; - 24.12, - 22.09) and from the Oecussi region (Population Attributable Fraction: -53.37, 95% CI; - 56.07, - 50.67; Difference: 60.49, 95% CI; 29.57, 91.41) had higher chance of having more births than those who were rich, educated, urban residents and from the Dili region, respectively. CONCLUSIONS: This study identified disproportionately higher burden of teenage birth among disadvantaged adolescents who are, poor, uneducated, rural residents and those living in regions such as Oecussi, Liquica and Manufahi, respectively. Policymakers should work to prevent child marriage and early fertility to ensure continuous education, reproductive health care and livelihood opportunities for adolescent girls. Specialized interventions should also be drawn to the subpopulation that had disproportionately higher adolescent childbirth.

[Subnational inequalities of early marriage and fertility among Chinese females from 1990 to 2010].

OBJECTIVE: To analyze the inequality of early marriage and adolescent fertility with respect to local economic development among Chinese females aged 15-19 years from 1990 to 2010. METHODS: Aggregated data were extracted from the Chinese National Census from 1990 to 2010. We calculated the ever-married rate and fertility rate of female adolescents aged 15-19 years. Using gross domestic product (GDP) per capita as an indicator for socio-economic status of a province, we calculated the slope index of inequality (SII) and the concentration index (CI) to analyze the subnational inequalities of early marriage and adolescent fertility. Weighted linear regression models were also established to assess the associations between GDP per capita and the ever-married rate/fertility rate. RESULTS: The ever-married rate for Chinese female adolescents aged 15-19 years decreased from 4.7% in 1990 to 1.2% in 2000, and rebounded to 2.1% in 2010. From 1990 to 2000, the fertility rate decreased from 22.0 per 1 000 to 6.0 per 1 000, and further decreased to 5.9 per 1 000 in 2010. In 1990, the socio-economic inequalities of the ever-married rate and fertility rate for female adolescents aged 15-19 years were not statistically significant (P for SII or CI>0.05). The values of SII revealed that, in 2000 and 2010, female adolescents with the lowest GDP per capita had an ever-married rate 2.4% (95%CI: 0.4-4.4) and 2.3% (95%CI: 0.3-4.2) higher than those with the highest GDP per capita, respectively. In the meantime, in 2000 and 2010, female adolescents with the lowest GDP per capita had a fertility rate 12.9 per 1 000 (95%CI: 5.4-20.5) and 9.3 per 1 000 (95%CI: 4.6-14.0) higher than those with the highest, respectively. In 2000 and 2010, the CIs for marriage were -0.32 (P=0.02) and -0.17 (P=0.03), respectively, and the CIs for childbirth were -0.37 (P<0.01) and -0.26 (P<0.01), respectively. In 2000, the ever-married rate and the fertility rate were estimated to increase by 1.4% (95%CI: 0.1-2.7) and 7.9 per 1 000 (95%CI: 2.9-12.8) with 100% increase in GDP per capita, respectively; in 2010, the numbers were 1.5% (95%CI: 0.1-2.9) and 6.7 per 1 000 (95%CI: 3.2-10.1), respectively. CONCLUSION: Subnational socio-economic inequality of early marriage and adolescent fertility existed in 2000 and 2010. Female adolescents residing in less-developed areas were more likely to engage in early marriage and childbirth. Reducing income inequality and increasing education investment for poverty-stricken areas seem to be effective measures to reduce this inequality.

Do village-level normative and network factors help explain spatial variability in adolescent childbearing in rural Honduras?

Adolescent childbearing rates are higher in Central America than almost anywhere else. However, in this research we discovered that adolescent childbearing exhibits variability from one village to another, and we might discover factors associated with this spatial variability that can help us understand key characteristics underlying the pattern of early childbearing. To do this, we assessed the village-level normative and network factors associated with adolescent birth (birth taking place before age 20 years) in rural Honduras and evaluated the geographic dispersion of these patterns. We used full population data from 24,937 people in 176 villages (81% of the eligible population) to assess prevalence and patterns of adolescent childbearing among women. We modeled the predictors of adolescent births among women younger than 21 years. After accounting for individual demographic characteristics, one of the strongest predictors of adolescent birth within the population was village-level collective norms about the acceptability of adolescent childbearing, based on aggregating normative measures from the entire population. The proportion of women in the village who had given birth as an adolescent was also strongly associated with an individual girl's likelihood of having given birth as an adolescent. We used full village-level network analyses to calculate social cohesion within the village. Normative pressure was strongly associated with the likelihood of an adolescent birth in villages with high cohesion (high network density) and was not associated or had a weak association in villages with low cohesion. On the other hand, the longer a girl had lived in the village, the stronger the association between the overall proportion of women in that village who gave birth as adolescents and the girl's own likelihood of having done so. Spatial analyses suggest that levels of adolescent births vary spatially across villages, as do the village-level normative factors associated with them.

Using three indicators to understand the parity-specific contribution of adolescent childbearing to all births.

INTRODUCTION: A strong focus on sexual and reproductive health of female adolescents is a key to achieving sustainable development goals, due to the large size of the current cohort in low-income and middle-income countries (LMICs) and adolescents' biological and social vulnerability. Several indicators of fertility among adolescents are in wide use, but the contribution of adolescent births to all births is poorly understood. We propose and calculate a package of three indicators capturing the contribution of adolescent births to all births, stratified by parity (first and second/higher). METHODS: We used Demographic and Health Survey data for 30 LMICs and vital registration for two high-income countries (to calculate levels and trends across a range of countries) for three time periods: 1990-1999, 2000-2009 and 2010-2015. The three indicators were calculated overall and by age thresholds (<16, <18 and <20 years) and exact ages, for each country and time point. Patterns of changes in indicators for the three cumulative thresholds over time are described. RESULTS: In the 30 LMICs, the percentage of all live births occurring to adolescents varied across countries, with a median of 18% for adolescents <20 years. Three countries (Jordan, Indonesia and Rwanda) had levels below 10%; Bangladesh had the highest at 33%. The contribution of adolescent first-order births to all first-order births was high; a median of 49%. Even among second-order and higher-order births, the contribution of adolescent childbearing was appreciable (median of 6%). Over the period under examination, the proportion of adolescent births among all live births declined in the majority of the LMICs. CONCLUSION: These three indicators add to our understanding of the scale of adolescent childbearing and can be used in conjunction with population estimates to assess the absolute need for age-appropriate and parity-appropriate reproductive, maternal and newborn healthcare and to monitor progress in improving young people's health.

Application of P/F Brass ratio method in the context of fast-paced adolescent fertility decline / Aplicación de la técnica P/F de Brass en un contexto de rápida caída de la fecundidad adolescente / Aplicação da técnica P/F de Brass em um contexto de rápida queda da fecundidade adolescente

Abstract Adolescent fertility -fertility rates at ages 15-19- fell substantially (around 30 percent) between 2000 and 2010. It was the first time Brazil experienced such a decline in those ages since 1970, when the census included one question about children born in the past 12 months. This phenomenon has an important implication for the P/F Brass ratio technique: it underestimates the cumulated current fertility up to age group 20-24 (F2), considering this cohort's previous fertility experience. Therefore, the P2/F2 value, used as an adjustment factor for the reported fertility level, is significantly overestimated. This paper discusses this issue and proposes an alternative to correct the reference period error in the 2010 Demographic Census in Brazil. The results of applying the proposed alternative in this specific context were very similar to those obtained using different techniques, thus supporting the strength of our alternative.

Resumo O Brasil experimentou, entre 2000 e 2010, pela primeira vez desde 1970, quando se introduziu o quesito sobre filhos nascidos vivos nos 12 meses anteriores à data de referência do censo, queda significativa (em torno de 30%) das taxas específicas de fecundidade declarada das mulheres entre 15 e 19 anos (f*1). Esse fenômeno tem uma importante consequência para a aplicação da técnica P/F de Brass: gera um erro, por falta, na fecundidade corrente acumulada até o grupo etário de 20 a 24 anos (F2), se tomada como experiência pregressa dessa coorte, levando a um valor de P2/F2, usado para ajustar o nível da fecundidade declarada, significativamente sobrestimado. O presente trabalho discute detalhadamente este problema e, por fim, propõe uma alternativa para se corrigir o erro de período de referência da fecundidade corrente do Censo Demográfico de 2010 do Brasil. A alternativa proposta, neste contexto específico, gerou estimativas de taxa de fecundidade total muito próximas às produzidas por outras técnicas.

Resumen Por la primera vez desde 1970 —cuando se introdujo la pregunta sobre nacidos vivos en los 12 meses anteriores a la fecha de referencia del censo— Brasil experimentó, entre 2000 y 2010, una disminución significativa de aproximadamente 30% de las tasas específicas de fecundidad declarada de mujeres entre 15 y 19 años (f*1). Este fenómeno trae una consecuencia importante para la aplicación de la técnica P/F de Brass: genera un error por falta en la fecundidad actual acumulada para el grupo de edad de 20 a 24 años (F2), lo que concomitantemente provoca una significativa sobrestimación en el valor de P2/F2 —utilizado para corregir el nivel de la fecundidad declarada—. Este trabajo discute este problema y propone finalmente una adaptación de la técnica original de Brass para aplicarla a los datos del censo de 2010. La alternativa propuesta generó, en este contexto específico, estimaciones de la tasa global de fecundidad similares a las producidas por otras técnicas.
