RESUMO

ISSUE: Postpartum depressive symptoms may be more prevalent and/or severe in vulnerable populations. BACKGROUND: Postpartum depression represents a serious mental health problem associated with maternal suffering. Despite the relevance and clinical implications of investigating pain during pregnancy and the association with postpartum depression, there is limited research on this topic. AIM: We evaluated the association between pain during pregnancy and postpartum depression symptoms in adolescent and adult women. METHODS: This study included 86 pregnant women (42 adolescents aged 13 to 18 years and 44 adults aged 23 to 28 years) from Trairi region, Northeastern Brazil. The evaluation of pain intensity and postpartum depression symptoms was conducted using the validated instruments of the Pelvic Pain Assessment Form and Edinburgh Postnatal Depression Scale (EPDS), respectively. Mann-Whitney and Kruskal-Wallis tests compared depressive symptoms in relation to pain status. FINDINGS: Overall, pregnant women reporting moderate to intense pain presented more depressive symptoms, with emphasis to "deep pain with intercourse" (p = .09), "burning vaginal pain after sex" (p = .01), "pelvic pain lasting hours or days after intercourse" (p = .06), and "pain with urination" (p = .09). When stratified by age group, significant associations were found only for the adolescents. DISCUSSION: Our results suggest that women reporting pain in different daily situations have higher EPDS scores. CONCLUSION: Pain during pregnancy is associated with postpartum depression symptoms, mainly among adolescents. Adequate screening and pain management during pregnancy may improve women's quality of life.

RESUMO

Background: Colombia has a high teen pregnancy (TP) rate. In 2018, one in five pregnancies was from teen mothers between 10 and 19 years of age. While TP rates are declining globally, Colombia's TP rate decline has been particularly low, despite sexual education and contraception campaigns. Other factors must be studied to prevent TP. Colombia has a long history of violence. We aim to assess whether there is a relationship between TP and exposure to violence in Colombia. Methods: Data from the Colombian Demographic and Health Survey 2015 and the Colombian National Department of Statistics were analyzed for association between TP and sexual violence, physical violence, physical punishment as a child, and community violence. Univariate, bivariate, multivariate, and multilevel binary logistic regression models were calculated using SPSS v.25 and HLM v.7. Results: Fifteen percent of teens were pregnant. Emotional violence was reported by 47%, sexual harassment by 27%, physical violence by 17%, physical punishment as a child by 7%, and unwanted sex by 2%. Unwanted sex (odds ratio [OR]: 3.18, 95% confidence interval [95% CI]: 1.96-5.16), sexual harassment (OR: 2.43, 95% CI: 1.89-3.14), and physical punishment (OR: 20.30, 95% CI: 7.96-22.81) were associated with adolescent pregnancy. In unadjusted models, emotional violence was associated (OR: 1.22, 95% CI 1.06-1.40) and community violence showed a tendency (OR: 1.24, 95% CI: 0.99-1.55). Physical violence was not associated. Conclusions: Violence exposure and particularly physical punishment, unwanted sex and sexual harassment were associated with TP incidence and should be considered risk factors for TP.

RESUMO

BACKGROUND: The prevalence of teenage pregnancy in Colombia is higher than the worldwide average. The identification of socio-geographical disparities might help to prioritize public health interventions. AIM: To describe variation in the probability of teenage maternity across geopolitical departments and socio-geographical intersectional strata in Colombia. METHODS: A cross-sectional study based on live birth certificates in Colombia. Teenage maternity was defined as a woman giving birth aged 19 or younger. Multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) was applied using multilevel Poisson and logistic regression. Two different approaches were used: (1) intersectional: using strata defined by the combination of health insurance, region, area of residency, and ethnicity as the second level (2) geographical: using geopolitical departments as the second level. Null, partial, and full models were obtained. General contextual effect (GCE) based on the variance partition coefficient (VPC) was considered as the measure of disparity. Proportional change in variance (PCV) was used to identify the contribution of each variable to the between-strata variation and to identify whether this variation, if any, was due to additive or interaction effects. Residuals were used to identify strata with potential higher-order interactions. RESULTS: The prevalence of teenage mothers in Colombia was 18.30% (95% CI 18.20-18.40). The highest prevalence was observed in Vichada, 25.65% (95% CI: 23.71-27.78), and in the stratum containing mothers with Subsidized/Unaffiliated healthcare insurance, Mestizo, Rural area in the Caribbean region, 29.08% (95% CI 28.55-29.61). The VPC from the null model was 1.70% and 9.16% using the geographical and socio-geographical intersectional approaches, respectively. The higher PCV for the intersectional model was attributed to health insurance. Positive and negative interactions of effects were observed. CONCLUSION: Disparities were observed between intersectional socio-geographical strata but not between geo-political departments. Our results indicate that if resources for prevention are limited, using an intersectional socio-geographical approach would be more effective than focusing on geopolitical departments especially when focusing resources on those groups which show the highest prevalence. MAIHDA could potentially be applied to many other health outcomes where resource decisions must be made.

RESUMO

ABSTRACT BACKGROUND: Exclusive breastfeeding is recommended for the first six months, and mother's age impact early weaning. Educational support and relevant information can increase breastfeeding rates. OBJECTIVE: To determine whether antenatal education enhances the maintenance, intention, and confidence in breastfeeding among adolescents. DESIGN AND SETTING: A prospective cohort study involving primiparous adolescents who gave birth at the Woman's Hospital (CAISM), Universidade Estadual de Campinas, Brazil. METHODS: Adolescent mothers were categorized into two groups based on the location of prenatal care: those at the Woman's Hospital (WH) who received antenatal education, and at the Primary Care (PC) who did not receive antenatal education. All adolescents received breastfeeding orientation during their postpartum hospital stay. The groups were compared using the Student's t-test, Mann-Whitney U test, and chi-squared test. Log-binomial models were used to compare the groups at different time intervals. RESULTS: The study included 132 adolescents: 59 in the WH group and 73 in the PC group. Six months postpartum, adolescents in the WH group demonstrated higher engagement in breastfeeding (P < 0.005) and exclusive breastfeeding (P = 0.04) than PC group. PC group showed greater lack of confidence in breastfeeding (P = 0.02) and felt less prepared (P = 0.01). Notably, all WH adolescents reported a stronger desire to breastfeed after antenatal education. CONCLUSION: Antenatal education significantly improves the maintenance, intention, and confidence of breastfeeding among adolescents. This education approach can be implemented across all healthcare levels and should be made accessible to all women throughout the pregnancy and postpartum period.

RESUMO

ABSTRACT Objective: To evaluate the distribution of the proportion of teenage mothers (PTM) in time and space and its relationship with socioeconomic indicators and social vulnerability. Methods: An ecological study was carried out with teenage mothers living in 322 census tracts in Foz do Iguaçu (state of Paraná, Brazil) between 2013 and 2019. Spatial clusters of teenage mothers were identified by spatial scanning and grouped into strata with different prevalence. The association between these strata and the individual social vulnerability of the mothers was evaluated using the Pearson's Chi-square test. Linear regression models were adjusted to evaluate the association between PTM and socioeconomic factors by census tract and temporal trend in PTM in different strata. Results: We identified five high prevalence clusters in peripheral regions and six with low prevalence in the central region of the municipality. Proportionally, there were more teenage mothers with a worse vulnerability index in the high prevalence stratum than in the low prevalence stratum. Places with worse socioeconomic conditions present higher PTM, a profile that did not change over time. For the increase of one unit in the Brazilian Deprivation Index and proportion of women responsible for the household, the PTM increased, respectively, by 3.8 (95%CI 3.1-4.4) and 0.086% (95%CI 0.03-0.14). There was a reduction in the global PTM in part of the period, which occurred later in the higher prevalence strata, but the proportions were stable again in the last years of study. Conclusion: Teenage pregnancy is concentrated in regions with worse socioeconomic conditions and greater maternal vulnerability and its behavior over time occurred differently in these areas.

RESUMO Objetivo: Avaliar a distribuição da proporção de mães adolescentes (PMA) no tempo e espaço e sua relação com indicadores socioeconômicos e vulnerabilidade social. Métodos: Realizou-se estudo ecológico com mães adolescentes residentes em 322 setores censitários de Foz do Iguaçu (PR) entre 2013 e 2019. Aglomerados espaciais de mães adolescentes foram identificados por varredura espacial e agrupados em estratos com diferentes prevalências. Avaliou-se a associação entre esses estratos e a vulnerabilidade social individual das mães pelo teste qui-quadrado de Pearson. Ajustaram-se modelos de regressão linear para avaliar associação entre a PMA e fatores socioeconômicos por setor censitário e tendência temporal da PMA nos diferentes estratos. Resultados: Identificaram-se cinco aglomerados de alta prevalência nas regiões periféricas e seis de baixa na região central do município. Proporcionalmente houve mais mães adolescentes com pior índice de vulnerabilidade no estrato de alta prevalência do que no de baixa. Locais com piores condições socioeconômicas apresentaram maior PMA, perfil que não mudou ao longo do tempo. Para o aumento de uma unidade do Índice Brasileiro de Privação e da proporção de mulheres responsáveis por domicílio, a PMA aumentou respectivamente 3,8 (IC95% 3,1-4,4) e 0,086% (IC95% 0,03-0,14). Houve uma redução na PMA global em parte do período, que ocorreu mais tardiamente nos estratos de maior prevalência, mas as proporções voltaram a ficar estáveis nos últimos anos de estudo. Conclusão: A gravidez na adolescência se concentra em regiões de pior condição socioeconômica e com maior vulnerabilidade materna e seu comportamento no tempo ocorreu, nessas áreas, de modo distinto.

RESUMO

Abstract Objectives: to analyze the temporal trend in maternal, care and newborns characteristics, in the city of Guarapuava, Paraná, Brazil in the period of 2010 to 2019. Methods: ecological temporal tendency study is based on Sistema de Informações sobre Nascidos Vivos (Live Birth Information System). To verify changes on the topics, the Prais-Winsten generalized linear regression was applied. Results: data from 28,919 live births were analyzed in 2019, 15.9% of the pregnancies were adolescents, 49.8% were cesarean deliveries and 9.2% were premature childbirths. A reduction in teenage pregnancy was observed, with annual percentage variation (APV) for mothers aged ten to 14 being -0.14% (p=0.005) and 15 to 19 years old -0.82% (p=0.004); there was an increase in mothers' schooling, with an APV of 60.09% (p=0.026) for eight to 11 years of schooling and 11.27% (p<0.001) for 12 or more; there was an increase of 15.33% (p<0.001) for seven or more prenatal consultations and a decrease in the Apgar classifications considering the risk, with scores from zero to two in the 1st minute with an APV=-0.12 (p=0.010) and scores from three to five in the 5th minute with APV=-0.07 (p=0.011). Conclusions: The city of Guarapuava presents important decreased tendencies in early pregnancy and an increase in mothers' schooling, besides the changes regarding the conditions in which their children are born and how they are welcomed.

RESUMO

Resumo A sífilis gestacional (SG) em adolescentes é um desafio para a saúde pública brasileira, com elevadas taxas de incidência. A testagem, diagnóstico e tratamento dos parceiros sexuais é indispensável para interromper a cadeia de transmissão, mas desde 2017 deixou de ser critério para o tratamento adequado da gestante. Buscamos analisar e sintetizar o conhecimento produzido sobre a atenção à saúde de parceiros sexuais de adolescentes com SG no Brasil. Realizamos uma revisão integrativa nas bases de dados BVS, SciELO e PubMed, selecionando artigos que abordavam SG e/ou sífilis congênita (SC) em adolescentes de 15 a 19 anos e que incluíam informações sobre os parceiros sexuais. Quarenta e um artigos foram analisados compreensivamente com auxílio do software WebQDA e classificados em duas categorias: (a) Abordagem dos parceiros sexuais no pré-natal, e (b) Papel dos parceiros sexuais no ciclo de transmissão da SG e da SC. Os estudos evidenciam que a abordagem do parceiro é deficitária, com ausência de dados sobre o perfil sociodemográfico e informações sobre testagem e tratamento. No âmbito da atenção primária à saúde não se encontram estudos que abordem fatores inerentes ao contexto de vulnerabilidade dos parceiros sexuais em relação ao enfrentamento da sífilis.

Abstract Gestational syphilis (GS) in adolescents is a challenge for Brazilian public health, with high incidence rates. Testing, diagnosis and treatment of sexual partners is essential to interrupt the chain of transmission, but since 2017 it is no longer a criterion for the proper treatment of pregnant women. We sought to analyze and synthesize the knowledge produced about the health care of sexual partners of adolescents with GS in Brazil. We carried out a systematic review in the BVS, SciELO and PubMed databases, selecting articles that addressed GS and/or congenital syphilis (CS) in adolescents aged 15 to 19 years and that included information about sexual partners. Forty-one articles were comprehensively analyzed using the WebQDA software and classified into two categories: a) Approach to sexual partners during prenatal care, and b) The role of sexual partners in the transmission cycle of GS and CS. The studies show that the partner's approach is deficient, with a lack of data on the sociodemographic profile and information on testing and treatment. In the context of Primary Health Care, there are no studies that address factors inherent to the context of vulnerability of sexual partners in relation to coping with syphilis.

RESUMO

Resumo O objetivo foi analisar a distribuição espacial da gravidez em menores de 14 anos e seis meses segundo regiões e municípios brasileiros e características sociodemográficas e de saúde das parturientes e nascidos vivos. Estudo ecológico, analisando o Sistema de Informação sobre Nascidos Vivos (SINASC), 2011-2021, em três grupos etários (<14 anos e 6 meses, 15-19 e 20 anos e mais), segundo variáveis demográficas e do parto. Foram aplicados os Índices Global e Local de Moran. No período foram 127.022 nascidos vivos de meninas 10-14 anos, na maioria negras, 21,1% em união estável ou casadas, com menor proporção de 7 consultas de pré-natal e captação no primeiro trimestre, maior proporção de baixo peso ao nascer e baixo índice de Apgar, residentes nas regiões Norte e Nordeste. A taxa média de nascidos vivos de 10-14 anos mostrou autocorrelação significativa com o espaço, especialmente em municípios do Centro-Oeste e Norte. A gravidez de 10 a 14 revela uma sequência de vulnerabilidades sofridas por essas meninas, pela gravidez em idade precoce, maior frequência entre negras, com implicações na morbimortalidade para ela e seus filhos; e pela violência presumida nesses casos, incluindo o acesso negado ao aborto legal.

Abstract The objective was to analyze the spatial distribution of pregnancy in children under 14 years and six months by Brazilian region and municipality and sociodemographic and health characteristics of pregnant women and live births. Ecological study analyzing the Live Birth Information System (SINASC) from 2011 to 2021 in three age groups (< 14 years and six months, 15-19 years, and 20 years and above) by demographic and birth variables. We applied the Global and Local Moran. A total of 127,022 live births to girls aged 10-14 years were identified during the period, most of whom were Black, 21.1% in common-law or married relationships, with a lower proportion of seven prenatal care appointments and enrollment in the first trimester, a higher proportion of low birth weight and low Apgar score, residing in the North and Northeast. The mean live birth rate for 10-to-14-year-old girls was significantly autocorrelated with space, especially in municipalities of the Midwest and North. Pregnancy from 10 to 14 years of age reveals several vulnerabilities suffered by these girls due to pregnancy at an early age, which is more common among Black women, with implications for morbimortality for them and their children and the presumed violence in these cases, including denied access to legal abortion.

RESUMO

BACKGROUND: Teenage pregnancy is a significant public health issue in Mexico; its prevalence oscillates around 20% of all pregnancies. Concurrently, alcohol, tobacco, and illicit drug use have become more common in this age group. METHODS: To estimate the prevalence of substance exposure in a population of pregnant teenagers, we conducted a prospective, observational, and cross-sectional study. The protocol was approved by the institutional review board. On informed consent, we asked 420 consecutive pregnant youngsters cared for at the outpatient obstetric service of a tertiary public regional women's and children's hospital in Nuevo León, in northeast Mexico, to answer a previously validated questionnaire to estimate the prevalence of alcohol, tobacco, or illicit drugs use during pregnancy. RESULTS: Of the 420 participants, 317 (75.5%) consumed at least one substance during pregnancy. Alcohol, either alone or in combination, was consumed by 300 (71.7%) participants. Tobacco was used by 117 (27.8%) participants, almost always in combination with other substances, while marijuana and other illicit drugs were consumed by 92 (21.9%) participants. Approximately one-fourth of the participants, 102 (24.1%) reported no substance use during pregnancy. CONCLUSIONS: In this series, the reported prevalence of alcohol, tobacco, and illicit drugs consumption during pregnancy, explored with a validated instrument, is higher than that previously reported in our country. This fact offers a worrying picture of another set of factors adding to the burden of teenage pregnancy.

INTRODUCCIÓN: El embarazo en la adolescencia ha adquirido gran importancia en la salud pública en México; su prevalencia oscila alrededor del 20% de los embarazos. Paralelamente, el consumo de alcohol, tabaco y drogas ilícitas en este periodo es cada vez más común en estas jóvenes. MÉTODOS: Para estimar la prevalencia de exposición a estas substancias en adolescentes embarazadas, se llevó a cabo un estudio prospectivo, observacional y transversal. El protocolo fue aprobado por los Comités de Ética e Investigación. Previo consentimiento informado, se solicito a 420 jóvenes embarazadas atendidas en la clínica prenatal del hospital materno-infantil más grande en Nuevo León, que respondieran un cuestionario previamente validado para estimar la prevalencia del consumo de substancias. RESULTADOS: De 420 participantes, 317 (75.5%) consumieron al menos una de estas sustancias durante el embarazo. El alcohol, solo o en combinación, fue consumido por 300 (71.5%). El tabaco fue usado por 117 (27.8%), casi siempre en combinación con otras sustancias, mientras que la mariguana y otras drogas ilícitas fueron consumidas por 92 (21.9%) participantes. Alrededor de una cuarta parte del grupo estudiado (24.1%) reportó no haber consumido ninguna de estas substancias en su embarazo. CONCLUSIONES: En nuestra serie, la prevalencia de consumo de alcohol, tabaco y drogas ilícitas durante el embarazo, explorada con un instrumento validado, es mayor de la reportada en estimaciones previas en nuestro país. Estos datos ofrecen un panorama preocupante de una serie de factores que se agregan a la carga del embarazo en la adolescencia.
