Introduction:Pregnancy is a period of several physiological, anatomical, psychological and social changes in a woman's life. Pregnant women and their babies need specific care.Adequate health care during the gestational period is essential for the prevention or reduction of maternal and child health problems. Objective: a) To identify the available evidence on the role of nursing in assisting pregnant women with hypertensive syndromes during pregnancy (Article 1); b) To analyze the agreement between data on pregestational weight, gestational weight gain, height, and systolic (SBP) and diastolic (DBP) blood pressure data recorded both in the prenatal care card and in the information obtained in the MINA-Brazil study (Article 2); c) To investigate the occurrence and factors associated with hypertensive disorders in pregnancy (HDP) and neonatal complications in women living in the Brazilian Western Amazon (Article 3); d) To investigate the socioeconomic and obstetric characteristics of adolescent parturients and their complications on maternal and neonatal health among participants of the MINA-Brasil birth cohort in the municipality of Cruzeiro do Sul, Acre ( Article 4). Methods: Baseline data from the MINA-Brazil cohort study were analyzed. Between February 2015 and May 2016, pregnant women enrolled in prenatal care in the urban area were screened and two evaluations were performed: 1st evaluation in the second trimester and the 2nd evaluation in the third trimester of pregnancy. Information on socioeconomic and demographic conditions, health and lifestyle history, and anthropometric measurements were obtained by the research team. Subsequently, between July 2015 and June 2016, a daily record of admissions for childbirth was carried out in the only maternity hospital in the municipality, starting the population-based birth cohort of the MINA-Brazil study.First, an integrative literature review was performed (Article 1), following data analyzes of agreement between anthropometric and blood pressure measurements recorded in the prenatal care card and measured by the MINA-Brazil study team (Article 2). Multiple Poisson regression models with robust variance were also used to assess factors associated with hypertensive disorders at childbirth (Article 3), and factors associated with adolescent parturients (Article 4). The level of statistical significance adopted was p <0.05. Results: In Article 1, overall 13 studies were selected for analysis, divided into 3 categories: 1. Nursing professionals' knowledge about hypertensive syndromes during pregnancy; 2. Nursing care for pregnant women with hypertensive syndromes during pregnancy and their newborns; 3. The systematization of nursing care in the care of hypertensive syndromes during pregnancy. In Article 2, data from 428 pregnant women were analyzed. There was moderate agreement between the information for self-reported pre-pregnancy weight (0.935) and height (0.913), and substantial agreement for the pregnant woman's weight in the second (0.993) and third (0.988) trim...
