RESUMO

Pre-pregnancy body mass index (pBMI) is a predictor of gestational weight gain (GWG). However, other factors, such as adipokines and inflammation markers, may also be associated with GWG. The aim of the study was to determine the association of leptin, adiponectin, irisin, and C-reactive protein, with GWG in adolescents. A longitudinal study was conducted from 2018 to 2023 in adolescents with a clinically healthy pregnancy. The assessments included sociodemographic and clinical data, pBMI, percent of body fat, serum concentrations of leptin, adiponectin, irisin, and high-sensitivity C-reactive protein (hsCRP), and total GWG adequacy. Cox regression models were performed, the outcome variables were inadequate and excessive GWG. In 198 participants, being overweight/obesity was marginally associated with a protective effect against inadequate GWG (HR = 0.44, 95%CI = 0.18-1.06), regardless of maternal characteristics and adipokines. Leptin (HR = 1.014, 95%CI = 1.008-1.021), and body fat percent (HR = 1.11, 95%CI = 1.05-1.17) were associated with a higher risk of excessive GWG, independent of other maternal variables such as pBMI, while adiponectin was associated with a lower risk. These findings suggest that, in Mexican adolescents, adipose tissue and its adipokines during pregnancy may play a more significant role in the final GWG than body weight.

RESUMO

BACKGROUND: Gestational weight gain below or above the Institute of Medicine recommendations has been associated with adverse perinatal and neonatal outcomes. Very few studies have evaluated the association between serum and red blood cell folate concentrations and gestational weight gain in adolescents. Additionally, zinc deficiency during pregnancy has been associated with impaired immunity, prolonged labor, preterm and post-term birth, intrauterine growth restriction, low birth weight, and pregnancy-induced hypertension. OBJECTIVE: The purpose of our study is to evaluate the association between serum concentrations of zinc, serum folate, and red blood cell folate, with the increase in gestational weight and the weight and length of the newborn in a group of adolescent mothers from Mexico City. RESULTS: In our study, 406 adolescent-neonate dyads participated. The adolescents' median age was 15.8 years old. The predominant socioeconomic level was middle-low (57.8%), single (57%), 89.9% were engaged in home activities, and 41.3% completed secondary education. Excessive gestational weight gain was observed in 36.7% of cases, while insufficient gestational weight gain was noted in 38.4%. Small for gestational age infants were observed in 20.9% of the sample. Low serum folate (OR 2.1, 95% CI 1.3-3.3), decreased red blood cell folate (OR 1.6, 95% CI 1.0-2.6), and reduced serum zinc concentrations (OR 3.3, 95% CI 2.1-5.2) were associated with insufficient gestational weight gain. Decreased serum zinc levels (OR 1.2, 95% CI 1.2-3.4) were linked to an increased probability of delivering a baby who is small for their gestational age. CONCLUSIONS: Low serum folate, red blood cell folate, and serum zinc concentrations were associated with gestational weight gain and having a small gestational age baby. Both excessive and insufficient gestational weight gain, as well as having a small gestational age baby, are frequent among adolescent mothers.

RESUMO

BACKGROUND: Preterm birth (PTB) is the main condition related to perinatal morbimortality worldwide. The aim of this study was to determine the indirect effects of neighbourhood socioeconomic status (NSES) on the risk of spontaneous PTB. METHODS: We carried out a retrospective case-control study including sociodemographic and obstetric data of multigravid women who gave birth at a maternity hospital in Tucumán, Argentina, between 2005 and 2010: 949 women without previous PTB nor pregnancy loss who delivered at term and 552 who had spontaneous PTB. NSES was estimated from the Unsatisfied Basic Needs index of census data. Variables selected through penalised regressions were used to create a data-driven Bayesian network; then, pathways were identified and mediation analyses performed. RESULTS: Maternal age less than 20 years mediated part of the protective effect of high NSES on spontaneous PTB [natural indirect effect (NIE) -0.0125, 95% confidence interval (CI) (-0.0208, -0.0041)] and on few prenatal visits (< 5) [NIE - 0.0095, 95% CI (-0.0166, -0.0025)]. These pathways showed greater sensitivity to unobserved confounders that affect the variables mediator-outcome in the same direction, and exposure-mediator in the opposite direction. They did not show sensitivity to observed potential confounders, nor to the parameterization used to define NSES. Meanwhile, urinary tract infections showed a trend in mediating the effect of low NSES on spontaneous PTB [NIE 0.0044, 95% CI (-0.0006, 0.0093), P 0.0834]. CONCLUSIONS: High NSES has protective indirect effects on spontaneous PTB risk, mainly associated with a lower frequency of teenage pregnancy.

RESUMO

Introduction: This study aimed to understand the sociocultural context of teenage pregnancy in an Ecuadorian city with a large indigenous population, to gauge the acceptability of a multifaceted pregnancy prevention program for adolescents, and to elicit perspectives on the optimal program design from adolescents and adult key informants. Methods: We ascertained qualitative data via an online, electronic survey administered from August to September 2020. Open- and closed-ended questions elicited perspectives relating to burden of adolescent pregnancies, acceptability of pregnancy prevention programs, and optimal design of future programs. Twenty-four adolescents (13-19 years of age) and 15 adult key informants working in the healthcare, business, and education sectors in Cotacachi completed the survey. Survey responses were analyzed using a structural and in vivo coding, and an inductive approach to consensus-building around key themes. Results: Most adolescent survey respondents (75%) believed that teen pregnancy is "fairly common" in Cotacachi, and 41.7% believed differences in teen pregnancy rates are not associated with ethnicity. In comparison, 66.7% of adult survey respondents said teen pregnancy disproportionately occurs among indigenous teenagers. Additionally, 45.8% of adolescent and 80% of adult survey respondents believed that a comprehensive sexual education program would help reduce teenage pregnancy rates by imparting reliable sexual health knowledge. Adult respondents noted that the past programs were unsuccessful in preventing teenage pregnancy because of these programs' inability to fully engage teenagers' attention, very short time duration, or inappropriate consideration of cultural context. Discussion: In Cotacachi, Ecuador, a sexual health education program is both desired and feasible according to adult and teenager key informants. A successful program must adapt to the cultural context and engage youth participation and attention.

RESUMO

OBJECTIVES: The aim of this study was to explore healthcare professionals' experience of pregnant and motherhood in adolescence in Haiti. METHODS: The methodology for collecting and analyzing qualitative data was based on John Dewey's social survey. The study was conducted in nine health institutions in the North and North-East departments of Haiti from October 2020 to January 2021. Data were collected through individual semi-structured interviews with 15 healthcare professionals. All interviews were audio-recorded. The recordings were listened to carefully and transcribed in verbatim form. After checking and validation, the verbatims in Word format were exported to QDA Miner software version 6.0.5 for coding. The data were analyzed using Paillé and Mucchielli thematic analyses. RESULTS: Health professionals such as gynecologists, nurses, midwives, nursing assistants, matrons and health workers took part in the study. These study participants indicate that teenage pregnancy and motherhood are social and public health problems whose negative consequences affect teenage girls, children, healthcare professionals, the healthcare system, and Haitian society in general. The services offered to adolescent girls are medical, educational, psychological, economic, and social in nature. When caring for pregnant adolescents during the transition to motherhood, healthcare professionals face many challenges that are linked to the socio-economic status and physiological reality of adolescents, as well as the healthcare system. CONCLUSIONS: Programs involving home care visits should also be set up to offer ongoing support to pregnant or parenting teenagers. The distribution of food aid or materials such as clothing, hygiene products and baby kits should also be considered.

RESUMO

This study investigated the association between gender role beliefs and the prevalence and likelihood of experiencing pregnancy among 8525 young women and girls aged 13-19 years in Colombia. The primary outcome of interest was adolescent pregnancy. Retrospective cross-sectional analysis utilised data from the 2015 Demographic and Health Survey (DHS) in Colombia, which included an add-on questionnaire on gender relations. Our analysis measured both pregnancy prevalence and pregnancy likelihood in relation to gender role beliefs. With one exception, young women who disagreed with traditionally conforming gender roles had a lower prevalence of pregnancy and were less likely to experience pregnancy than those who agreed with them. The highest likelihood of pregnancy prevalence and likelihood was found among those who agreed with statements suggesting male dominance and those who agreed with women's homemaking responsibilities. The greater the adherence to traditionally conforming gender role beliefs, the higher the likelihood of experiencing pregnancy during adolescence. Girls' and young women's adherence to traditional gender role beliefs appeared to be a risk factor for adolescent pregnancy. Our findings support Colombia's current sex education policies and practices within the framework of gender equity, and evidence the link between gender equity and girls' and young women's reproductive health.

RESUMO

Teenage pregnancy carries adverse consequences for health and well-being. In this article, we investigate the perceived causes, consequences and cycles of violence and disadvantage associated with teenage pregnancy in Tambogrande, Peru using an applied anthropological approach. Data were drawn from a larger project investigating the relationship between water insecurity and gender-based violence in Indonesia and Peru. The analysis presented here is derived from 49 semi-structured interviews and 5 focus groups with local community members and stakeholders in Peru. Study participants highlighted two main factors contributing to teenage pregnancy in Tambogrande: machismo and religious deterrents to contraceptive use. Participants described how these factors overlapped, resulting in gendered power imbalances that increased the risk of violence, decreased educational opportunities, and reduced the economic independence of women. However, study participants stated that educational interventions targeting machismo could reduce teenage pregnancy and break the associated cycle of disadvantage. Future research will further investigate local social and gender norms to inform the design of a rights-based educational intervention, targeting upstream factors associated with teenage pregnancy in this area.

RESUMO

Resumo O objetivo do estudo foi investigar as características socioeconômicas e obstétricas de parturientes adolescentes e suas complicações sobre a saúde materna e neonatal. Trata-se de uma análise de dados da linha de base da coorte de nascimentos MINA-Brasil conduzida no município de Cruzeiro do Sul, estado do Acre. Utilizou-se teste qui-quadrado para comparar características das puérperas adolescentes com as adultas e modelos múltiplos de regressão de Poisson com variância robusta para avaliar fatores associados. Entre as puérperas estudadas, 26,2% (IC95%: 24,0-28,4) eram adolescentes. Os fatores associados ao parto na adolescência foram ter nove anos ou menos de estudo (RPaj:1,36; IC95%: 1,14-1,61), pertencer aos menores quartis do índice de riqueza (1° quartil: RPaj:1,40; IC95%: 1,08-1,80) (2° quartil: RPaj:1,37; IC95%: 1,08-1,74), ser primigesta (RPaj:3,69; IC95%: 2,98-4,57), baixo IMC pré-gestacional (RPaj:1,28; IC95%: 1,04-1,57), infecção urinária na gravidez (RPaj:1,25; IC95%: 1,07-1,46) e menos de seis consultas de pré-natal (RPaj:1,42; IC95%: 1,21-1,66). Pobreza, baixa escolaridade, primigestação, baixo IMC pré-gestacional, infecção urinária na gestação e menor número de consultas de pré-natal foram associados ao parto na adolescência em município da região Norte do Brasil.

Abstract The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil.

RESUMO

Resumen Antecedentes: En México los embarazos adolescentes son 77 por cada 1,000. De los nacimientos anuales, el 17% son de madres adolescentes, con casi 350,000. Objetivo: Explicar por qué las adolescentes se embarazan a pesar del conocimiento de métodos anticonceptivos. Métodos: Con un estudio exploratorio y observacional, se evaluaron a 300 adolescentes embarazadas de 15 a 19 años, que no tenían antecedentes de consumo de sustancias adictivas y cuyos embarazos no fueron resultado de una violación.. Se aplicó el cuestionario de funcionamiento familiar y una entrevista de los antecedentes sociodemográficos. Resultados: El inicio de vida sexual fue a los 12 años para el 1.7%, de las participantes, a los 13 para el 7.3%, a los 14 para el 18.7%, a los 15 para el 36%, a los 16 para el 19.3% y las restantes (17%) tuvieron un inicio a los 19 años. El 100% manifestó que conocía métodos anticonceptivos, incluyendo la píldora del día siguiente. Conclusiones: El embarazo a temprana edad viene acompañado de mitos sociales e individuales sobre el conocimiento de la sexualidad humana, la anticoncepción y la vida amorosa. El embarazo representa para las jóvenes tener un objeto de amor y obtener un lugar en el mundo y dentro sus familias.

Abstract Background: In Mexico, teenage pregnancy is 77 for every 1,000. In terms of annual births, 17% are from teenage mothers, which are almost 350,000. Objective: To explain why teenage girls get pregnant in spite of knowing about contraceptives. Method: An observational and exploratory study by which 300 pregnant teenage girls between 15 and 19 years old were evaluated, with no history of substance abuse and whose pregnancies were not the result of rape. A questionnaire on family dynamics and an interview about their sociodemographic background were applied. Results: The first sexual intercourse for 1.7% of the participants was at 12 years old; for 7.3%, at 13; for 18.7%, at 14; for 36%, at 15; for 19.3%, at 16, and for the remaining 17%, near 19 years old. All of them (100%) stated they knew about contraceptives, including the morning-after pill. Conclusions: Pregnancies at an early age come with individual and social myths about the knowledge of human sexuality, contraception, and love life. For these young women, a pregnancy represents an object of love and obtaining a place in the world and within their families.

RESUMO

Introduction: Teenage pregnancy is defined as a pregnancy occurring between ages 10 and 19 (Loredo-Abdlá et al., 2017; Belitzky, 1985; Kaplanoglu et al., 2015), and is associated with increased morbidity and mortality for both mother and child. Several factors have been identified with increased risk of a teenage pregnancy, including incomplete sexual education awareness and increased exposure at a young age. In addition, an earlier onset of sexual intercourse, or coitarche, has been linked to a higher risk of teenage pregnancy. Early menarche, defined as first menstruation before the age of 12 has been previously identified as a risk factor for an earlier coitarche, possibly linking an early menarche with a higher incidence of teenage pregnancy. This study aims to compare and determine the relationship between the incidence of teenage pregnancy with early menarche and coitarche in a low income setting. Design Setting Participants Interventions Main Outcome Measures: A cross sectional review of electronic records of women admitted for delivery in a second level center in northeastern Mexico, being a low-income setting, where 814 teenage and 1474 adult mothers were included. Results: Primigravid teenagers had earlier menarche and coitarche than adult counterparts and opted for postpartum contraception more frequently. Linear regression analysis revealed significant unadjusted beta coefficients between age at first pregnancy and coitarche (0.839) and menarche (0.362). Menarche and coitarche had a significant linear regression association of 0.395. Conclusion: We found amongst primigravid patients that teenagers had earlier menarche and coitarche than adults, which in turn correlated to their age at their first pregnancy.

RESUMO

OBJECTIVES: To study sexually transmitted Chlamydia trachomatis infections (STCTs), teenage pregnancies, and payment defaults in individuals born preterm as proxies for engaging in risk-taking behavior. STUDY DESIGN: Our population-based register-linkage study included all 191 705 children alive at 10 years (8492 preterm [4.4%]) born without malformations in Finland between January 1987 and September 1990 as each mother's first child within the cohort. They were followed until young adulthood. We used Cox regression to assess the hazards of STCTs, teenage pregnancies, payment defaults, criminal offending, and substance abuse by gestational age. Gestational age was considered both as a continuous and categorical (extremely, very, moderately, late preterm, early term, post term, and full term as reference) exposure. RESULTS: A linear dose-response relationship existed between gestational age and STCT and teenage pregnancy; adjusted hazard for STCT decreased by 1.6% (95% CI, 0.7%-2.6%), and for teenage pregnancy by 3.3% (95% CI, 1.9%-4.8%) per each week decrease in gestational age. Those born extremely preterm (23-27 completed weeks) had a 51% (95% CI, 31%-83%) lower risk for criminal offending than their full-term born counterparts, and those born very preterm (range, 28-31 weeks) had a 28% (95% CI, 7%-53%) higher hazard for payment defaults than those born at full term. Gestational age was not associated with substance abuse. CONCLUSIONS: The lower risk-taking that characterizes people born preterm seems to generalize to sexual and to some extent criminal behavior. Those born very preterm are, however, more likely to experience payment defaults.

RESUMO

Teenage pregnancy rates in the Peruvian Amazon are double the national average and among the highest in Latin America. Peruvian women living in rural, underserved and Amazon areas are more likely to become teenage mothers but the factors contributing to this socio-demographic trend are unclear. Thirty-one interviews and ethnographic observations of teenage and adult mothers living in the Peruvian Amazon were conducted to examine how social class and gender impacted their motherhood experiences. Despite preconceptions concerning the undesirability of teenage pregnancy, results show that teenage and adult mothers have similar experiences of motherhood. Both groups of women lack career and educational opportunities and are therefore economically dependent on men. This, combined with the cultural valorisation of motherhood, pushes them toward pregnancy and motherhood. In other words, pregnancy is a response to a lack of career and educational opportunities and not vice versa. The one difference found between teenage and adult mothers is that the former have less agency over reproductive decision making. In conclusion, motherhood among teenage and adult mothers in the Peruvian Amazon is an adaptive mechanism that gives women protection and fulfilment but is also the result of gender and class constraints that limit their life choices.

RESUMO

Over the past few decades growing attention has focused on the perceived challenge of adolescent pregnancy and the need for girls to make 'smart choices'. This has generated considerable debate particularly because of the failure of many programmes and interventions to consider the structural constraints faced by young women in accessing sexual and reproductive health and rights (SRHR). Yet limited attention has been given to the views and experiences of girls' parents and caregivers, many of whom were often adolescent parents themselves. We use data from the Real Choices, Real Lives longitudinal study conducted by Plan International to consider how the experiences of girls' families shape their attitudes to teenage pregnancy in the Dominican Republic and El Salvador. Many families believe girls need to practise abstinence and avoid men and boys but given the lack of provision for SRHR faced by young women this response is not unexpected.

RESUMO

En Venezuela, el embarazo en adolescentes es un problema de salud pública, por su frecuencia, la repercusión sobre la calidad de vida de las madres, de sus hijos y de la sociedad en general; además, aun así, puede ser atendido y es factible su disminución. En 2014, Venezuela presentaba la Tasa Específica de Fecundidad más alta de Suramérica; y ocupaba el cuarto lugar, entre los países de Latinoamérica. Para estudiar el embarazo de adolescentes en el país se analizan los datos oficiales disponibles de la última década (2003-2012), en números, porcentajes y tasas. Asimismo, se analizan los nacimientos de madres adolescentes (2014/2015), recabados en dos hospitales públicos y dos privados: (11596 nacimientos: 2438 de madres adolescentes). De éstos: 2.403 (25,8%), en hospitales públicos y 35 (1,5%), en los privados. Del sector público, 95% de los hijos de adolescentes, son hijos de madres de 15 a 19 años y 5% de 10 a 14 años. Las tasas del grupo de 15 a 19 años (indicador oficial internacional), aumentaron en 2011 y 2012. Se analizan otras cifras y características: edad de las madres, frecuencia de legrado. En 2012, último año de información nacional disponible, se registraron (Instituto Nacional de Estadística-INE): 143 491 nacidos vivos, hijos de adolescentes, (10 a 19 años, según la OMS), que representan 23,4% del total anual de nacimientos. El embarazo en adolescentes constituye un fracaso social multisectorial, que recicla la pobreza y aumenta el subdesarrollo. Su importancia amerita la creación y aplicación de políticas públicas, así como estrategias específicas y permanentes para disminuir su incidencia(AU)

Abstract: Teenage pregnancy in Venezuela is a public health problem due to its incidence and repercussions over life-quality of mothers, their children, and the society in general. Even though with proper attention there is an incidence decrease possibility. In 2014 the Venezuelan Age-Specific Fertility Rate (15-19 age group) was the highest in South America and was the fourth among Latin America and the Caribbean nations. To study teenage pregnancy in the country last decade official available data (2003-2012) was analyzed by number, percentage, and rates. Between 2014 and 2015 the number of births from teenage mothers at two public and two private hospitals was analyzed (11 596 births: 2.438). Of those, 2.403 births were registered at public hospitals (25.8%) while 35 (1.5%) were at private clinic. At public hospitals 95% of live births were from teenage mothers (15-19 years) and 5% were mothers aged 10-14. In 2011 and 2012 the fertility rates for 15­19-year-olds (international official indicator) increased. Other characteristics and tendencies are analyzed: age of mothers, abortion frequency and prenatal visits. According to the INE (National Institute of Statistics) in 2012, last year of available information, there were 143 491 live births from teenage mothers (aged 10-19 WHO) registered in Venezuela, which represents the 23.4% of the total number of annual births. Pregnancy of teenagers is a social multisectoral failure that recycles poverty and increase underdevelopment. The magnitude of the problem requires the design and implementation of public policies as well as specific permanent strategies to reduce the incidence(AU)

RESUMO

Teenage pregnancy remains a global problem because of its consequences for the teenager, her child, her family, and society. In Haiti, this type of pregnancy burdens the family economy. In addition, the adolescent fertility rate is still high, despite efforts to reduce it. This article aims to analyze the perception and experiential experience of relatives of pregnant adolescents in Haiti. A qualitative study design based on Dewey's social survey was conducted. Data were collected from 17 relatives (partners, parents, guardians, and others) of pregnant adolescents in Haiti's North and Northeast departments. These data were analyzed using thematic analysis. According to the results, teenage pregnancy is seen as a disaster or a social problem in Haiti. It leads to many psychosocial and economic difficulties for the relatives, who are the only source of economic and social support for pregnant adolescents. Considering the vulnerability of relatives, policies, and interventions aimed at reducing the negative consequences of teenage pregnancy should consider this group of individuals.

RESUMO

Introduction: To analyze the factors (socio-demographic, clinical, prenatal care, delivery, postpartum data and anthropometric measures) associated with the birth of small for gestational age newborns.Methods: A cross-sectional study was performed with 15 years old or younger postpartum adolescents divided into small-for-gestational-age newborn (SGA) and non-small-for-gestational age newborn groups (NSGA). Socio-demographic, clinical, prenatal care, delivery, postpartum data and anthropometric measures (triceps skinfold (TS), and mid-arm circumference, (MAC)) were collected.Results: 8,153 women gave birth at the obstetric ward and 364 (4.46%) ≤ 15 years old adolescents were enrolled in the study. The proportion of SGA newborns was 34.61%. The SGA group attended fewer prenatal visits (p = 0.037), had a higher prevalence of nutritional status classified as "very low weight" (p < 0.001) and vaginal delivery (p = 0.023), compared to the NSGA group. The nutritional status and vaginal delivery remained significant even after adjustment for confounders. The prevalence risk for SGA birth was 30% higher in the group of mothers with nutritional status classified as "very low weight" (odds ratio 1.30, 95% confidence interval 1.13 to 1.50) (p < 0.001).Conclusions: 15.4% of adolescents ≤ 15 years of age had an arm circumference compatible with the "very low weight" condition, demonstrating the high prevalence of poor maternal nutritional status in this group. The birth of SGA among adolescents ≤ 15 years of age is independently associated with maternal nutritional status classified as "very low weight" by the mid-arm circumference measures (MAC).
