RESUMEN
BACKGROUND: The aims of the study were to: (a) describe BMI-for-age trajectories in children up to four years of age; (b) evaluate the association between prepregnancy maternal BMI and the BMI-for-age trajectories. METHODS: Data from 3218 (75.3% of the original cohort) children from the Pelotas 2015 Birth Cohort were analyzed. Prepregnancy BMI (kg/m2) was measured on the perinatal interview. Z-scores of BMI-for-age were calculated for children at three months, 1, 2 and 4 years. Trajectories were identified using a semi-parametric group-based modeling approach. Multinomial logistic regression was used to test the association between prepregnancy BMI (weight excess: BMI ≥ 25 kg/m2) and BMI-for-age trajectories. RESULTS: Four trajectories of the BMI-for-age, in z-score, were identified and represent children in the "increasing", "adequate", "stabilized" and "risk for weight excess" group. A total of 196 children (7.1%) belonged to the group that was at risk of weight excess. Adjusted analyses showed that children whose mothers presented prepregnancy weight excess had 2.36 (95%CI 1.71; 3.24) times more risk of belonging to group "risk for weight excess" when compared to those children whose mothers presented underweight/normal weight before pregnancy. CONCLUSION: The risk of weight excess in children up to 4 years of age were greater in mothers who presented prepregnancy weight excess.

STUDY QUESTION: Do women with multi-partner fertility or multi-partner behavior conceive more often than women with a single partner? SUMMARY ANSWER: Women with multi-partner behavior conceived more frequently and had more children than non-multi-partner women and multi-partner fertility women. WHAT IS KNOWN ALREADY: Some women experience having biological children with more than one partner: those women are considered as multi-partner fertility. Women with multi-partner fertility have more children and are substantially less likely to have planned their first birth. Individuals with multi-partner fertility become parents at a younger age, largely with unintended first births, and often do so outside of marriage, compared to parents with two or more children from only one partner. Unmarried women, particularly, are at greater risk of having unintended births. Studies are still scarce and there is a need to assess the contribution of women's multi-partners fertility and multi-partner behavior to family composition, particularly in low- and middle-income countries. STUDY DESIGN, SIZE, DURATION: This longitudinal birth cohort study evaluated 1215 mothers whose children belonging to the 2004 Pelotas Birth Cohort were their first pregnancy, and who attended the perinatal, 48-month, 6-year, and 11-year follow-ups. Information was obtained from responses to a questionnaire. The number of years at risk of having children was treated as the exposure, and woman's multi-partner behavior and multi-partner fertility, dichotomized as 'Yes' or 'No', were considered endogenous treatment variables. PARTICIPANTS/MATERIALS, SETTING, METHODS: Data from mothers with a first pregnancy, and with information available from the perinatal, 48-month, 6-year, and 11-year follow-ups, were evaluated. The exposures studied were women's multi-partner behavior and multi-partner fertility (i.e. conceiving/giving birth), and the outcomes evaluated were the number of pregnancies, the number of children currently alive, and experience of unintended pregnancies from the birth of the child belonging to the 2004 birth cohort until 11 years later. Crude and adjusted risk ratios (RRs) were estimated through Poisson regression with endogenous treatment effects, robust standard errors, and their respective 95% CI. MAIN RESULTS AND THE ROLE OF CHANCE: Multi-partner behavior women had 16% (RR 1.16; 95% CI: 1.08-1.25) and 11% (RR 1.11; 95% CI 1.03-1.19) greater risk of having a new pregnancy and having more children alive, respectively, than those with non-multi-partner behavior. Women with multi-partner fertility had a 23% (RR 1.23; 95% CI: 1.11-1.37) and 20% (RR 1.20; 95% CI: 1.08-1.33) higher risk of having a new pregnancy and having more children alive, respectively, than single-partner fertility mothers. Women who had multiple partners (i.e. behavior), as well as those with multi-partner fertility, showed a lesser proportion of unintended pregnancies when compared to the non-multi-partner ones (34.08%; 95% CI: 28.12-40.60 vs 36.17%; 95% CI: 31.93-40.63), compared to their counterparts' single partners fertility (33.16%; 95% CI: 26.83-40.17 vs 36.26%; 95% CI: 31.85-40.92), although these findings were not statistically significant. LIMITATIONS, REASONS FOR CAUTION: The mothers who were not included in the study owing to missing data for some of the follow-up had 5-11 years of education, a low socio-economic level, and were younger, thus the number of pregnancies may be underestimated because these groups presented a high number of pregnancies and children alive. We did not have information about the complete woman's conjugal history. Therefore, misclassification error of the exposure may be present and, consequently, the measures of association may be underestimated. Furthermore, this study was not truly representative of the Pelotas study female population. WIDER IMPLICATIONS OF THE FINDINGS: In this study of multi-partner behavior and fertility, women who have multiple partners may be less likely to get married and have a stable partner. Compared to single-partner women, multi-partner fertility and multi-partner behavior women may predominantly become pregnant for the purpose of having children, rather than accidentally.

OBJECTIVES: The aim of this study was to investigate the effect of maternal's depression trajectory in the first 1000 days of the child's life on the prevalence of early childhood dental caries (ECC), in a birth cohort. MATERIALS AND METHODS: All infants born in Pelotas in 2015 were identified, and the mothers were invited to participate in the cohort. A total of 3645 children were included in the study. The outcome was ECC at 48 months of age assessed according to ICDAS. Maternal depression was collected using Edinburgh Postnatal Depression Scale (EPDS) antenatally, at 3, 12, and 24 months of age. Maternal depressive symptom trajectory variables were created using group-based trajectory models and adopting two cutoff points. Poisson regression model with robust variance was used to identify the total effect of maternal depressive symptom trajectories on ECC, adjusting by confounders. RESULTS: A total of 29.2% of the mothers presented a high trajectory for screening of depression, and 18.8% presented a high trajectory of depression diagnosis. The prevalence of ECC was 26.7%. After adjusted analysis, maternal depression trajectories (screening and diagnosis) from pregnancy to 24 months increased the risk for ECC at 48 months of age (RR = 1.14; 95% CI 1.02-1.28 and RR = 1.19; 95% CI 1.05-1.35). CONCLUSIONS: Children from mothers with high depression trajectory had higher risk of having dental caries at 48 months compared to children from mothers with low depression trajectory. CLINICAL RELEVANCE: Strategies of early detection and treatment of maternal mental disorders during the Golden Period should be considered of high priority in health services since it could impact positively in children's life.

BACKGROUND: Motherhood has been associated with reduced leisure-time physical activity (LTPA) levels. We aim to assess maternal LTPA patterns from preconception to 4 years postpartum. METHODS: The study was developed with mothers from the Pelotas 2015 Birth Cohort, Southern Brazil (n = 4273). LTPA data were self-reported for preconception, antenatal, and 3, 12, 24, and 48 months postpartum. Information on LTPA referring to preconception (3 mo before pregnancy) and each gestational trimester was retrospectively collected in perinatal. The prevalence of active mothers was calculated according to recommendations (≥150 min/wk). We described changes in LTPA between follow-ups and estimated the probability of mothers being active according to previous LTPA. We used group-based trajectory analysis to identify patterns of LTPA throughout the follow-ups. RESULTS: The prevalence of active mothers during leisure time decreased in pregnancy and postpartum compared with preconception. At 12 months postpartum, LTPA levels rose again, but at 48 months, the rates of active mothers still had not returned to preconception levels. Prior LTPA engagement was an important determinant of the maintenance of LTPA. Trajectory analysis identified 4 patterns of maternal LTPA, and â¼80% of mothers were allocated to the "always inactive" group. Higher education and income, working outside the home, multiple births, and participating in the PAMELA study intervention were associated with a higher probability of mothers not being included in this predominantly inactive group. CONCLUSIONS: Motherhood is associated with declining rates of women meeting physical activity recommendations during pregnancy and early postpartum.

Objectives: To estimate inequalities in demand for family planning satisfied with modern methods among women in Latin America and the Caribbean, with an emphasis on Brazil and Mexico, and to calculate the scenario for recovery of modern contraceptive coverage by expanding access to long-acting contraceptives (LARC) after the COVID-19 pandemic. Methods: National health surveys from 2006 to 2018 were used to estimate the demand for family planning satisfied with modern methods and how it was affected by the COVID-19 pandemic. The scenario included three variables: coverage, health outcomes, and costs. Considering coverage, United Nations Population Fund data were used to estimate the impact of COVID-19 on access to contraception in Latin America and the Caribbean. Health outcomes were assessed with the Impact 2 tool. Direct investment was used to evaluate cost-effectiveness. Results: Substantial inequalities were found in the use of modern contraceptive methods before the pandemic. We showed the potential cost-effectiveness of avoiding maternal deaths by introducing LARCs. Conclusions: In the scenario predicted for Brazil and Mexico, the costs of modern family planning and averted disability-adjusted life years are modest. Governments in Latin America and the Caribbean should consider promoting LARCs as a highly efficient and cost-effective intervention.
RESUMEN
Adverse childhood experiences (ACEs) have been found to predict many negative life outcomes. However, very little evidence exists on Intimate Partner Violence (IPV) and Child Maltreatment (CM). We investigated the impact of maternal ACEs on IPV and CM in three different: cumulative risk, individual adversities and particular groupings of ACEs. The 2015 Pelotas Birth Cohort, Southern Brazil, has followed a population-based sample mothers and children repeatedly until children were aged 4 years, when mothers provided data on ACEs, and current IPV and CM. ACEs were examined in three different ways: (i) as a cumulative risk score; (ii) individual adversities; and (iii) patterns of ACEs (Latent Class Analysis: LCA). One quarter (25.4%) of mothers reported having 5+ ACEs in childhood. Compared to mothers with no ACEs, those who reported 5+ ACEs, had 4.9 (95%CI 3.5; 6.7) times the risk of experiencing IPV and 3.8 (95%CI 2.5; 5.6) times the risk of reporting child maltreatment. LCA results also highlighted the major influence of multiple ACEs on later IPV and CM. However, individual ACEs related to violence (exposure to abuse or domestic violence) showed some specificity for both later IPV and CM, over and above the influence of cumulative childhood adversity. This is the first large study to demonstrate a strong link between maternal ACEs and both IPV and CM. Cumulative ACE exposure and some specificity in effects of childhood violence are important for later IPV and CM. Integrated prevention is essential for reducing the intergenerational transmission of adversity and violence.

BACKGROUND: Studies comparing the outcome of spontaneous versus assisted reproductive technologies (ART) pregnancies report heterogeneous results. Despite the success of ART to overcome infertility, concern is growing regarding both its safety and its effect on maternal and child health. The objective of this study was to compare maternal and child-health outcomes after ART relative to natural conception. METHODS: A population-based birth cohort study was carried out among pregnant women expected to deliver in 2015 in Pelotas, southern Brazil. Maternal outcomes included pregnancy complications and gestational weight gain. Gestational age, weight, intrauterine growth restriction, length and head circumference, and 1-min and 5-min Apgar, as well as health problems at birth and breastfeeding were defined as offspring outcomes. Statistical analyses were performed using linear and logistic regression. G-formula was used to perform mediation analysis. RESULTS: The study included 4252 babies born by spontaneously pregnancies and 23 babies born after ART. Adjusted analyses showed that children conceived from ART presented lower means of gestational age (p = 0.001), birth weight (p = 0.002), length (p < 0.001), and head circumference at birth (p = 0.02). However, more than 90% of the effect of ART over these outcomes was mediated by multiple pregnancy. CONCLUSION: Our findings suggest that the possible negative effect on the child-health outcomes is due mainly to the higher incidence of multiple pregnancies and not because of ART. The reasons for the increase in adverse pregnancy outcomes associated with ART singleton pregnancies are still uncertain and warrants further research. Further large-population studies are needed to confirm these results.

Background: Medication use during pregnancy is a common practice that has been increasing in recent years. The aim of this study is to describe medication use among pregnant women from the 2015 Pelotas (Brazil) Birth Cohort Study. Methods: This paper relies on a population-based cohort study including 4270 women. Participants completed a questionnaire about the antenatal period, including information about medication use. We performed descriptive analyses of the sample and the medications used and adjusted analyses for the use of medications and self-medication. Results: The prevalence of medication use was 92.5% (95% CI 91.7-93.3), excluding iron salts, folic acid, vitamins, and other minerals. The prevalence of self-medication was 27.7% (95% CI 26.3-29.1). In the adjusted analysis, women who had three or more health problems during pregnancy demonstrated higher use of medicines. Self-medication was higher in lower income groups and among smokers and multiparous women (three pregnancies or more). Acetaminophen, scopolamine, and dimenhydrinate were the medications most commonly used. Conclusions: This study describes the pattern of drug use among pregnant women in a population-based cohort study, with a high prevalence of self-medication. Greater awareness of the risks of self-medication during pregnancy is required, focusing on groups more prone to this practice, as well as ensuring qualified multidisciplinary prenatal care.

Background: This study describes medication use by women up to 3 months postpartum and evaluates the association between medication use by women who were still breastfeeding at 3 months postpartum and weaning at 6 and 12 months. Methods: Population-based cohort, including women who breastfed (n = 3988). Medications were classified according to Hale's lactation risk categories and Brazilian Ministry of Health criteria. Duration of breastfeeding was analysed using Cox regression models and Kaplan-Meier curves, including only women who were still breastfeeding at three months postpartum. Results: Medication use with some risk for lactation was frequent (79.6% regarding Hale's risk categories and 12.3% regarding Brazilian Ministry of Health criteria). We did not find statistically significant differences for weaning at 6 or 12 months between the group who did not use medication or used only compatible medications and the group who used medications with some risk for lactation, according to both criteria. Conclusions: Our study found no association between weaning rates across the different breastfeeding safety categories of medications in women who were still breastfeeding at three months postpartum. Therefore, women who took medications and stopped breastfeeding in the first three months postpartum because of adverse side-effects associated with medications could not be addressed in this analysis.

BACKGROUND: Many low- and middle-income countries recommend micronutrient supplements for pregnant women to improve their nutritional status, prevent possible deficiencies and avoid fetal healgth consequences. This study evaluated the influence of socioeconomic status on the use of folic acid, iron salts and other vitamins and minerals among pregnant women in the 2015 Pelotas Birth Cohort. METHODS: This population-based birth cohort study was carried out with 4270 women. Participants were interviewed during pregnancy and at the maternity hospital about the antenatal period; including the use of iron salts, vitamins and other minerals. Descriptive analyses were performed to characterize the sample. The analyses were adjusted according to socioeconomic variables (maternal education, ethnicity, household income). RESULTS: The overall prevalence of the use of folic acid, iron salts or other vitamins and minerals was 91.0% (95% CI: 90.1-91.8). Specifically, 70.9% (95% CI: 69.5-72.3) used folic acid, 72.9% (95% CI: 71.5-74.3) used iron compounds, and 31.8% (95% CI: 30.3-33.2) used other vitamins or minerals. In the adjusted analysis, the use of iron salts was associated with nonwhite mothers, with ≤4 years of education and whose family income was less than or equal to the monthly minimum wage. The use of folic acid and other vitamins and minerals was associated with white mothers who were more highly educated and had a higher family income. CONCLUSION: Although folic acid and other vitamins and minerals were more frequently used in white, richer and more educated mothers, which indicates inequality, iron supplements were more frequently used in the poorer, less educated nonwhite mothers, suggesting the opposite association for this supplement.

BACKGROUND: Non-supine infant sleep position is an important modifiable risk factor for sudden unexpected death in infancy. The aim of this study was to assess the prevalence of supine sleep position and associated factors among 3-month-old infants from a birth cohort in the city of Pelotas, southern Brazil. METHODS: The present study evaluated longitudinal data from the 2015 Pelotas Birth Cohort. Study outcome was supine infant sleep position, defined as the appropriate position, among 3-month-old children. Demographic, socioeconomic, behavioral, and health characteristics collected at birth and at the 3-month follow-up were investigated as possible associated factors. The prevalence of each associated factor was investigated, and crude and hierarchical adjusted analyses were performed using Poisson regression. RESULTS: Among the 4108 infants assessed in this study, 2274 (55.4%) slept in supine position at 3 months and only 66 (1.6%) in prone position. Maternal white skin color, higher family income and maternal schooling, advanced maternal age, maternal cohabiting with a partner, receiving counseling from health care professionals and non-bed-sharing were associated with higher prevalence of infants sleeping in supine position at 3 months. All these variables remained associated in our hierarchical adjusted analyses except maternal cohabitation with a partner. Participants with white mothers were more likely to sleep in supine position (PR: 1.23; 95%CI: 0.75-0.89) compared to participants with black mothers. Those belonging to the richest quintile were more likely to sleep in supine position (PR: 1.49; 95%CI: 1.35-1.65) compared to those who belong to the poorest. Mothers aged 31-36 years were more likely to choose supine sleep position (PR: 1.65; 95%CI: 1.42-1.92) compared to mothers younger than 19 years. CONCLUSIONS: The findings of the present study showed the influence of maternal age, socioeconomic status, and counseling on infant sleep habits as predictors of choice of infant sleep position in a Brazilian population. It is recommended to implement informative campaigns and public policies to at-risk population and to improve recommendations from health care professionals.

BACKGROUND: Children in many low- and middle-income countries (LMICs) are at high risk for exposure to violence and later violent behaviour. The World Health Organization has declared an urgent need for the evaluation and implementation of low-cost parenting interventions in LMICs to prevent violence. Two areas of significant early risk are harsh parenting and poor child cognitive and socio-emotional development. Parenting interventions suitable for LMIC contexts have been developed targeting these risk factors and have been shown to have promising effects. However, their impact on child aggression, a key precursor of violence, has yet to be determined. The Pelotas Trial of Parenting Interventions for Aggression (PIÁ) has been designed to address this issue. METHODS: We are conducting a randomised controlled trial to evaluate two early parenting interventions for mothers of children aged between 30 and 42 months in a Brazilian city. The first of these, dialogic book-sharing (DBS), aims to promote child cognitive and socio-emotional development; and the second, the ACT Raising Safe Kids Program (ACT), is designed to reduce harsh parenting. These interventions are being compared with a control group receiving neither intervention. Three hundred and sixty-nine families in a birth cohort are being randomly allocated to one of the three groups (DBS, ACT, Control). Facilitators deliver the interventions to groups of five to 10 mothers at weekly sessions for 8 weeks in DBS and 9 weeks in ACT. Independent assessments of parenting and child development are being made before the interventions, shortly afterwards, and at follow-up 6 months later. The primary outcome is child aggression, and the two main secondary outcomes are: (1) child cognitive and socio-emotional development and (2) harsh parenting. Longer-term outcomes will be investigated as the birth cohort is followed into late childhood, adolescence, and adulthood. DISCUSSION: The Pelotas Trial of Parenting Interventions for Aggression (PIÁ) aims to evaluate the impact of two early parenting interventions on child aggression and several other key risk factors for the development of violence, including aspects of parenting and child cognition and socio-emotional functioning. The study is being carried out in a LMIC context where violence constitutes a major social and health burden. Since the two interventions are brief and, with modest levels of training, readily deliverable in LMIC settings, a demonstration that they benefit parenting and reduce risk factors for violence would be of major significance.

Trichomoniasis is a curable sexually transmitted infection (STI) that has been reported to be linked to exposure to human immunodeficiency virus (HIV), although few studies have described this association. The purpose of this study was to focus on the incidence of trichomoniasis in low-income women, its relation to HIV status, viral load levels and TCD4+cell counts, among other risk factors, using an in vitro culture as a diagnostic test. A cross-sectional study among 267 women (103 HIV-positive and 164 HIV-negative) was conducted in 2015. The overall prevalence of Trichomonas vaginalis (TV) infection was 6.4%. Among HIV-positive and HIV-negative women, the prevalence was 3.9% and 7.9%, respectively, yet these results were not statistically different (p=0.1878). The factors associated with TV infection were cigarette smoking (OR= 3.52), vaginal itching (OR=4.43) and bacterial vaginosis (BV) (OR= 5.29). HIV status, TCD4+ cell count and viral load were not associated with TV infection in this group. The prevalence rates found, lower than those observed in other studies, may be due to the fact that the women evaluated in the present study are part of a low-risk population as well as the limited sample size of HIV positive women

Importance: Interventions to reduce postpartum depression have mainly focused on enhancing screening to increase treatment rates among women. Preventive approaches are timely from a population health perspective, particularly in low- and middle-income countries where access to mental health services is limited. Objective: To assess the efficacy of regular exercise during pregnancy on the prevention of postpartum depression. Design, Setting, and Participants: This randomized clinical trial examines a prespecified secondary outcome of the Physical Activity for Mothers Enrolled in Longitudinal Analysis (PAMELA) Study, a parallel-group, randomized clinical trial. This trial was nested in the 2015 Pelotas (Brazil) Birth Cohort Study. Between August 27, 2014, and March 14, 2016, pregnant women between 16 and 20 weeks of gestation with no contraindications to exercise were randomized 1:2 to the intervention group or control group via computer-generated randomization using a block size of 9. Data were analyzed from March 7 to May 2, 2018. Interventions: Participants assigned to the intervention were engaged in a 16-week supervised exercise program including aerobic and resistance training delivered in 60-minute sessions 3 times per week. Main Outcomes and Measures: Postpartum depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale 3 months after birth. A score of 12 or greater was defined as screening positive for postpartum depression. Primary analysis was performed on a complete case basis (90% of participants who had the primary end point ascertained). Results: A total of 639 participants (mean [SD] age, 27.1 [5.1] years; mean gestational age, 16.5 [1.5] weeks) were randomly assigned to the intervention group (n = 213) or control group (n = 426). Compliance with the protocol, defined as having engaged in at least 70% of exercise sessions, was low (40.4%). There was no significant difference in mean (SD) scores for postpartum depression between the intervention group (4.8 [3.7]) and the control group (5.4 [4.1]) (mean difference, -0.6; 95% CI, -1.3 to 0.1). There was also no significant difference in rates of postpartum depression between the intervention group (12 of 192 [6.3%]) and the control group (36 of 387 [9.3%]) (odds ratio, 0.65; 95% CI, 0.33-1.28). Instrumental variable analysis indicated that noncompliance may have attenuated the effect estimates obtained in the primary analysis. Conclusions and Relevance: Moderate-intensity exercise during pregnancy did not lead to significant reductions in postpartum depression. However, noncompliance to the intervention protocol was substantial and may have led to underestimations of the possible benefits of exercise. The point estimates for this study are in the same direction as the previous randomized clinical trial on this topic. Future studies on how to promote regular exercise during pregnancy to improve compliance, particularly targeting young and less educated women, are warranted before further trials are undertaken.

BACKGROUND: The disrespect and abuse of women during the process of childbirth is an emergent and global problem and only few studies have investigated this worrying issue. The objective of the present study was to describe the prevalence of disrespect and abuse of women during childbirth in Pelotas City, Brazil, and to investigate the factors involved. METHODS: This was a cross-sectional population-based study of women delivering members of the 2015 Pelotas birth cohort. Information relating to disrespect and abuse during childbirth was obtained by household interview 3 months after delivery. The information related to verbal and physical abuse, denial of care and invasive and/or inappropriate procedures. Poisson regression was used to evaluate the factors associated with one or more, and two or more, types of disrespectful treatment or abuse. RESULTS: A total of 4275 women took part in a perinatal study. During the three-month follow-up, we interviewed 4087 biological mothers with regards to disrespect and abuse. Approximately 10% of women reported having experienced verbal abuse, 6% denial of care, 6% undesirable or inappropriate procedures and 5% physical abuse. At least one type of disrespect or abuse was reported by 18.3% of mothers (95% confidence interval [CI]: 17.2-19.5); and at least two types by 5.1% (95% CI: 4.4-5.8). Women relying on the public health sector, and those whose childbirths were via cesarean section with previous labor, had the highest risk, with approximately a three- and two-fold increase in risk, respectively. CONCLUSIONS: Our study showed that the occurrence of disrespect and abuse during childbirth was high and mostly associated with payment by the public sector and labor before delivery. The efforts made by civil society, governments and international organizations are not sufficient to restrain institutional violence against women during childbirth. To eradicate this problem, it is essential to 1) implement policies and actions specific for this type of violence and 2) formulate laws to promote the equality of rights between women and men, with particular emphasis on the economic rights of women and the promotion of gender equality in terms of access to jobs and education.

OBJECTIVE: To describe the epidemiological profile of reported cases of syphilis in pregnancy and congenital syphilis in five states (Amazonas, Ceará, Espírito Santo, Rio de Janeiro, and Rio Grande do Sul) and the Federal District using data from the Reportable Disease Information System (SINAN). METHOD: This descriptive study including an ecological and cross-sectional evaluation employed data from SINAN Net. The syphilis detection rate in pregnancy and the congenital syphilis incidence rate per 1 000 live births were calculated. To identify pregnant women with syphilis who had an outcome of congenital syphilis, the two SINAN databases were linked using the RecLink software. Because the data were representative at the state (not national) level, comparisons were made between the units of the federation and not with the sum of cases. RESULTS: A growth in the syphilis detection rate in pregnancy was detected, ranging from 21% (Amazonas) to 75% (Rio de Janeiro) during the study period. The incidence of congenital syphilis followed the same trend of growth (ranging from 35.6% in the Federal District to 63.9% in Rio Grande do Sul), except for a 0.7% decline in Amazonas. The proportion of women with an outcome of congenital syphilis who had prenatal care ranged from 67.3% in Amazonas to 83.3% in the Federal District. Of the pregnant women with syphilis, 43% had an outcome of congenital syphilis. In pregnant women with syphilis and an outcome of congenital syphilis, maternal diagnosis was made prenatally in 74% and at delivery in 18%. The moment of diagnosis was ignored in 8% of the women. CONCLUSION: The increase in the syphilis detection rate may have resulted from an increase in the report rate. Ongoing monitoring of pregnant women is essential to eliminate syphilis.

BACKGROUND: Antenatal depression (AD) is a major public health issue but evidence regarding its prevalence and associated factors in low and middle-income countries (LMICs) is limited. The aim of the study was to estimate the prevalence and identify risk factors for AD among Brazilian pregnant women. METHODS: All women living in the urban area of the city of Pelotas, Southern Brazil, with confirmed pregnancy and estimated delivery date in the year 2015, were invited to take part. Eligible pregnant women were recruited from health services. Symptoms of antenatal depression were assessed using the Edinburgh Postnatal Depression Scale (EPDS) by face-to-face interviews. A cutoff-point of 13 or more was used to define probable AD. RESULTS: EPDS scores were available for 4130 women. The prevalence of AD was 16% (95%CI 14·9-17·1). After adjustment for potential confounders, the factors most strongly associated with higher EPDS scores were a previous history of depression (PR 2·81; 95%CI 2·44-3·25), high parity (PR 1·72; 95%CI 1·38-2·15 - ≥2 children vs. 1 child) and maternal education (PR 5·47; 95%CI 4·22-7·09 - 0-4 vs. ≥12 years of formal education). LIMITATIONS: EPDS was administered through face-to-face interviews rather than questionnaires and some women may have felt uncomfortable reporting their symptoms leading to underreporting and consequently underestimation of the prevalence found. CONCLUSION: AD prevalence is substantially higher in Brazil than in high-income countries (HICs) but similar to other LMICs. Our study identified relevant risk factors that may be potential targets to plan interventions, particularly a history of depression.

RESUMO Objetivo Descrever o perfil epidemiológico dos casos notificados de sífilis em gestantes e sífilis congênita nos estados brasileiros do Amazonas, Ceará, Espírito Santo, Rio de Janeiro e Rio Grande do Sul e no Distrito Federal a partir de dados do Sistema Nacional de Agravos de Notificação (SINAN). Métodos Estudo descritivo incluindo avaliação ecológica e transversal. Foram utilizados dados do SINAN Net. Foram calculadas a taxa de detecção de sífilis em gestantes e a taxa de incidência de sífilis congênita por 1 000 nascidos vivos. Para identificar as gestantes notificadas com sífilis com desfecho de sífilis congênita, as duas bases do SINAN foram relacionadas por meio do software RecLink. Como os dados eram de representatividade regional, as comparações foram feitas entre as unidades da federação, e não com a soma dos casos. Resultados A taxa de detecção de sífilis em gestantes cresceu entre 21% (Amazonas) e 75% (Rio de Janeiro). A incidência de sífilis congênita seguiu o mesmo perfil de incremento, variando de 35,6% no Distrito Federal a 639,9% no Rio Grande do Sul, com redução de 0,7% no Amazonas. A realização de pré-natal nas mulheres com desfecho de sífilis congênita variou de 67,3% no Amazonas a 83,3% no Distrito Federal. Das gestantes com sífilis, 43% tiveram desfecho notificado de sífilis congênita. Nas gestantes com sífilis e desfecho de sífilis congênita, o diagnóstico materno ocorreu durante o pré-natal em 74% e no parto em 18%. Em 8% das mulheres ignorava-se o momento do diagnóstico. Conclusão O incremento nas taxas de detecção de sífilis pode ter resultado do aumento na notificação. O monitoramento constante em gestantes é essencial para a eliminação desses agravos.

RESUMEN Objetivo Describir el perfil epidemiológico de los casos notificados de sífilis en embarazadas y de sífilis congénita en los estados brasileños de Amazonas, Ceará, Espírito Santo, Rio de Janeiro y Rio Grande do Sul y en el Distrito Federal a partir de datos del Sistema Nacional de Información de Enfermedades de Notificación Obligatoria (SINAN). Métodos Estudio descriptivo que incluye una valoración ecológica y transversal. Se utilizaron datos de la Red SINAN. Se calcularon la tasa de detección de sífilis en embarazadas y la tasa de incidencia de sífilis congénita por 1000 nacidos vivos. Para identificar a las embarazadas notificadas con sífilis que causó sífilis congénita, se relacionaron las dos bases del SINAN por medio del software RecLink. Como los datos eran representativos a nivel regional, las comparaciones se hicieron entre las unidades de la federación y no con la suma de los casos. Resultados La tasa de detección de sífilis en embarazadas aumentó entre 21% (Amazonas) y 75% (Rio de Janeiro). La incidencia de sífilis congénita siguió el mismo perfil de incremento, variando de 35,6% en el Distrito Federal a 63,9% en Rio Grande do Sul, con una reducción de 0,7% en Amazonas. Los controles prenatales en las mujeres que tuvieron hijos con sífilis congénita variaron de 67,3% en Amazonas a 83,3% en el Distrito Federal. De las embarazadas con sífilis, en el 43% de los casos se notificó sífilis congénita. En las embarazadas con sífilis que causó sífilis congénita, el diagnóstico materno fue durante la etapa prenatal en 74% de los casos y en el parto en 18% de los casos. En 8% de las mujeres se desconocía el momento del diagnóstico. Conclusión El incremento de las tasas de detección de sífilis puede haber sido consecuencia de una mayor notificación. Es esencial el seguimiento constante de las mujeres embarazadas para eliminar el aumento de esas enfermedades.

INTRODUCTION: This study assessed the rate of request for the serological diagnosis of Chagas disease among human immunodeficiency virus (HIV)-infected patients treated at the Specialized Care Service of Pelotas, Rio Grande do Sul, Brazil. METHODS: This cross-sectional study used secondary data obtained from the medical records of 252 patients aged between 18 and 75 years. RESULTS: The serological diagnosis of Chagas disease was requested only in 3.2% of cases. CONCLUSIONS: The results demonstrate poor adherence to protocols on the part of healthcare professionals, indicating the need to reevaluate the procedures applied to HIV-infected patients from endemic regions for both diseases.
