Introduction: Psychosocial stress during pregnancy has long-lasting and important consequences in the following generations, as it can affect intrauterine development. The impact on the developing immune system is notoriously important due to the associated morbidity and mortality in the first years of life. Little attention has been given to the role of violence during pregnancy (VDP), especially its impact on infant infectious morbidity.

Background: Dental eruption is part of a set of children´s somatic growth phenomena. The worldwide accepted human dental eruption chronology is still based on a small sample of European children. However, evidence points to some population variations with the eruption at least two months later in low-income countries, and local standards may be useful.

Aim: To analyze the association between neonatal near miss and infant development at two years.
Methods: Data from two birth cohorts, one conducted in Ribeirão Preto (RP)/São Paulo and the other in São Luís (SL)/Maranhão, were used. The cognitive, motor and communication development of children was evaluated using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III).

Sugar-sweetened beverages (SSB) consumption may be associated with a reduction in bone mineral density (BMD). The aim of this study was to evaluate the association between the consumption of SSB and BMD among young people. We performed a cross-sectional study that evaluated 6620 young people (18-23 years of age) from three Brazilian birth cohorts (Ribeirão Preto, Pelotas, and São Luís).

We hypothesize that early events of diabetes and cardiovascular disease continuums would be ongoing and associated in adolescents. We investigated the association between the Insulin Resistance Phenotype and the Vascular Risk Phenotype at the end of the second decade of life and indirect pathways from social vulnerability, alcohol consumption, and body fat mass. It is a population-based study in the RPS cohort of 18-19 years (n = 2,515), São Luís, Brazil.

Thus, eating habits can influence sleep duration and, consequently, affect the quality of life of young people. This study thus aims to estimate the association of consumption of or minimally processed, processed, and ultra-processed foods with sleep durations in adolescents.

Objective: To assess the direct, indirect, and total effects of violence during pregnancy on perinatal outcomes, and to evaluate the effect of violence as a moderator of the mediated relationship of depression with perinatal outcomes.
Methods: Data was collected from the prenatal study and follow-ups of the BRISA cohort, São Luís, Maranhão, Brazil. The perinatal outcomes investigated were: birth weight (BW), intrauterine growth restriction (IUGR) and gestational age (GA).

Objective: To investigate the association between ultra-processed food consumption at 23-25 years of age and measurements of body composition-fat mass, fat mass distribution and lean mass at 37-39 years of age in Brazilian adults.
Methods: 1978/1979 birth cohort study conducted with healthy adults from Ribeirão Preto, São Paulo, Brazil. A total of 1,021 individuals participated in the fat mass analysis (measured by air displacement plethysmography) and 815 in the lean mass analysis and fat mass distribution (assessed by dual energy X-ray absorptiometry).

Background: A nutrient-poor and hypocaloric diet may be associated with lower handgrip strength (HGS), whereas a high-quality or balanced diet may be associated with higher HGS. However, no study has used the NOVA system for classifying food by their degree of processing.
Objective: To analyze the association between food consumption according to the degree of food processing and HGS in Brazilian teenagers.

Preterm birth (PTB) and postpartum depression (PPD) are important public health issues, and although literature mainly supports the association between them, some reviews have highlighted methodological limitations in the studies in this field, restricting the interpretation of such finding. This study aimed at assessing the association between PTB and PPD, by comparing groups of preterm and full-term mothers in two Brazilian cities with contrasting sociodemographic indicators. This prospective convenience cohort study assessed 1421 women during pregnancy, at childbirth, and in the postpartum period.

This innovative work proposes the development of a computational methodology for analysis and differentiation, based on the time-frequency domain, between the chaotic pattern of WS and ZVCS hypsarrhythmia. The EEG signal time-frequency analysis is carried out from the Continuous Wavelet Transform (CWT).

Introduction: The brain-derived neurotrophic factor (BDNF) and neural growth factor (NGF) are widely expressed in the brain and play an important role in neuroplasticity, neurogenesis, and increased neuronal connections. Previous studies have shown that reduced serum levels of these proteins are associated with disorders in human sleep.
Objective: Current study evaluates the prevalence in adolescents of excessive daytime sleepiness (EDS) and sleep quality, and analyzes the influence of these factors on BDNF and NGF serum levels.
Background: The mistreatment of women during pregnancy, childbirth, and the puerperium is a global public health problem besides being a violation of human rights. However, research exploring the consequences of mistreatment of women and newborns is scarce.
