RESUMO

OBJECTIVE: Pregnancy in adolescence is a global health issue, especially in developing countries. Additionally, the recommended gestational weight gain (GWG) is usually based on pre-pregnancy BMI and that might be complex for pregnant teens. The study objective was to compare three different methods of BMI classification and suggest the best way of determining pre-pregnancy BMI and monitoring GWG among pregnant adolescents. DESIGN: Pre-pregnancy weight, weight at first prenatal visit, height, sociodemographic, reproductive and perinatal data were collected. Weighted kappa and McNemar statistics were used to assess agreement between the classification methods. SETTING: Prof. Dr Jose Aristodemo Pinotti Women's Hospital, University of Campinas, Brazil.ParticipantsPrimiparas younger than 19 years of age and with less than 20 weeks of gestational age (n 150). RESULTS: BMI of the primiparas was determined according to the WHO recommendation for adult women, the Child Growth Standards (CGS) and their gynaecological age (GA). The WHO and GA measurements presented a strong agreement with each other (κ w=0·99; 95 % CI 0·97, 1·00), but did not agree with the CGS classification (κ w=0·62; 95 % CI 0·50, 0·74 by WHO; κ w=0·62; 95 % CI 0·51, 0·74 by GA). Also, inadequate GWG was observed in 72·2 % of cases and was correlated with a higher rate of caesarean birth. CONCLUSIONS: BMI classification according to the CGS differed from WHO and GA. However, CGS and WHO agreed on perinatal outcomes. We recommend using BMI classification by WHO to assess pregnant adolescents, since it is easily applied and better known among health professionals.

RESUMO

OBJECTIVE: This study sought to evaluate the anemia prevalence and effect of anemia treatment in pregnant adolescents. METHODS: A cross-sectional study. Data from perinatal outcomes, serum hemoglobin level and iron supplementation were collected. Samples were divided into three groups: pregnant adolescents without anemia, with treated anemia and with untreated anemia. Frequencies, means, standard deviations and Chi-squared values were calculated. The significance level was 5%, and the software used was Epi-info 7. RESULTS: The study included 458 pregnant adolescents. The mean age was 16 years old, and the prevalence of anemia was 41.27% (189). Mild, moderate or severe anemia were presented in 65.60%, 33.86% and 0.52%, respectively, of study participants. Among pregnant adolescents with anemia, 87.24% received treatment with iron supplementation. Preterm labor (p = 0.003), gestational age at birth <37 weeks (p = 0.036) and stillbirth (p = 0.004) showed an association with nontreated anemia. Positive HIV was more prevalent in adolescents with nontreated anemia (p = 0.018). The cesarean rate was 36.90%, with no difference between groups. CONCLUSION: Anemia is a public health problem among pregnant adolescents, and iron supplementation reduces negative neonatal outcomes. Treatment adherence by a multidisciplinary and qualified prenatal care team can be key in reducing adverse neonatal outcomes associated with pregnancy during adolescence.

RESUMO

Objective To determine methods of contraception used by adolescents before and after pregnancy. Methods A cross-sectional study was performed, and data were collected from medical records of all teens in puerperal consultation at the Hospital da Mulher - José Aristodemo Pinotti (Caism), Universidade Estadual de Campinas (CAISM), São Paulo, Brazil, between July 2011 and September 2013. The inclusion criterion was being 10 to 19 years old, and the exclusion criterion was having a first consultation 90 days after childbirth. Statistical analyses were performed with averages, standard deviations, percentages, correlations and Fisher's exact tests using the SAS program, version 9.4. Results A total of 196 adolescents in postpartum consultation were included (44 days after childbirth on average). The majority was older than 14 years (89%), with an average age of 16.2 years, and the most were exclusively breast-feeding (70%). Before pregnancy, the use of any contraceptive methods was mentioned by 74% adolescents; the most frequent use was combined oral contraceptive followed by condom. The main reason for abandoning the use of contraception was the occurrence of an unintended pregnancy (41%), followed by reports of side effects (22%), behavior issues (18%) and desire for pregnancy (16%). A positive correlation was found between the age of the adolescent at the moment of childbirth, the age of menarche (r = 0.3), and the first sexual intercourse (r = 0.419). Vaginal delivery occurred in 76% of the cases. After birth, depot medroxyprogesterone acetate (DMPA) was the contraception method most frequently used (71%), followed by oral contraceptives (11.8%) and intrauterine devices (IUDs, 11.2%). Conclusions The most prescribed contraceptive method before pregnancy in adolescents who had childbirth was combined oral contraceptives. Many of the study participants had an unintended pregnancy. After childbirth, the most used contraceptive method was DMPA. To improve contraception and reduce the chance of unintended pregnancies among adolescents, we should promote the use of long-acting reversible contraceptives (LARCS).

RESUMO

OBJECTIVE: Reviewed literature regarding exercise effects on pregnancy-related hypertensive disorders, analyzing basic science perspectives and clinical studies. METHODS: Scientific databases were accessed by research strategy combining Medical Subject Headings terms. Studies published between 2000 and 2015, in English, Portuguese, and Spanish language, were considered. RESULTS: Studies were classified into: recommendations for exercise on high-risk pregnancy; animal models for hypertension in pregnancy; exercise on hypertensive disorders in animal models and pregnant women. CONCLUSION: There are several animal models to mimic hypertensive disorders in pregnancy; however, clinical studies are still needed for exercise recommendation in pregnant women with hypertensive disorders.

RESUMO

Physical exercise is recommended for all healthy pregnant women. Regular practice of exercises during pregnancy can provide many physical and psychological benefits, with no evidence of adverse outcomes for the fetus or the newborn when exercise is performed at mild to moderate intensity. However, few pregnant women engage in this practice and many still have fears and doubts about the safety of exercise. The objective of the present study was to inform the professionals who provide care for Brazilian pregnant women about the current recommendations regarding physical exercise during pregnancy based on the best scientific evidence available. In view of the perception that few systematic models are available about this topic and after performing several studies in this specific area, we assembled practical information of interest to both the professionals and the pregnant women. We also provide recommendations about the indications, contraindications, modalities (aerobics, resistance training, stretching and pelvic floor training), frequency, intensity and duration indicated for each gestational trimester. The review addresses physical exercise recommendation both for low risk pregnant women and for special populations, such as athletes and obese, hypertensive and diabetic subjects. The advantages of an active and healthy lifestyle should be always reinforced during and after gestation since pregnancy is an appropriate period to introduce new habits because pregnant women are usually more motivated to adhere to recommendations. Thus, routine exams, frequent returns and supervision are recommended in order to provide new guidelines that will have long-term beneficial effects for both mother and child.

RESUMO

Os exercícios físicos podem e devem ser recomendados para todas as gestantes saudáveis. Sua prática regular durante a gestação pode promover inúmeros benefícios físicos e psicológicos, além de não haver evidências de desfechos adversos para o feto e/ou recém-nascido, quando realizados em intensidade leve a moderada. No entanto, poucas gestantes aderem a essa prática e muitas ainda têm receios e dúvidas quanto à segurança da sua realização. Este artigo teve como objetivo a informação e a disseminação entre profissionais de saúde, que assistem às gestantes no Brasil, das atuais recomendações sobre exercício físico durante a gestação, baseadas nas melhores evidências científicas disponíveis. Diante da percepção de existirem poucos modelos sistematizados a respeito, e após a realização de vários estudos nesta área específica, reunimos informações práticas de interesse para os profissionais e gestantes. Ademais, incluímos recomendações quanto às indicações, contraindicações, modalidades (exercícios aeróbicos, treinamento de resistência muscular, alongamento e exercícios do assoalho pélvico), frequência, intensidade e duração dos exercícios para cada trimestre gestacional. Abordamos recomendações de exercícios físicos tanto para as gestantes de baixo risco quanto para populações especiais de mulheres, como atletas, hipertensas, diabéticas e obesas. A conscientização dos benefícios auferidos por um estilo de vida mais saudável durante e após a gestação deve ser sempre lembrada e estimulada pela equipe atendente. Por estarem as gestantes muito próximas dos especialistas e altamente motivadas, oportunizam-se exames de rotina, retornos frequentes e supervisão para uma série de novas orientações que podem refletir em sua saúde e na de seu bebê a longo prazo.

RESUMO

OBJECTIVE: To assess occurrence of severe maternal complications associated with ectopic pregnancy (EP). METHOD: A multicenter cross-sectional study was conducted, with prospective surveillance of potentially life-threatening conditions (PLTC), maternal near miss (MNM), and maternal death (MD). EP complications, patient sociodemographic/obstetric characteristics, and conditions of severity management were assessed, estimating prevalence ratios with respective 95% CI. Factors independently associated with greater severity were identified using multiple regression analysis. RESULTS: Of the 9.555 severe maternal morbidity patients, 312 women (3.3%) had complications after EP: 286 (91.7%) PLTC, 25 (8.0%) MNM, and 1 (0.3%) MD. Severe maternal outcome ratio (SMOR) was 0.3/1000 LB among EP cases and 10.8/1000 LB among other causes. Complicated EP patients faced a higher risk of blood transfusion, laparotomy, and lower risk of ICU admission and prolonged hospitalization than women developing complications resulting from other causes. Substandard care was the most common in more severe maternal morbidity and EP cases (22.7% MNM and MD versus 15% PLTC), although not significant. CONCLUSION: Increased maternal morbidity due to EP raised awareness about the condition and its impact on female reproductive life. No important risk factors for greater severity were identified. Care providers should develop specific guidelines and interventions to prevent severe maternal morbidity.

RESUMO

BACKGROUND: The aim of this study was to assess severe maternal morbidity (SMM) and near miss (NM) cases among adolescent girls and women over 35 years of age in the Brazilian Network for Surveillance of Severe Maternal Morbidity, using a set of standard criteria, compared to pregnant women aged 20 to 34 years. METHODS: A cross-sectional multicenter study conducted in 27 referral obstetric units in Brazil. All pregnant women admitted to these centers during a one-year period of prospective surveillance were screened to identify cases of maternal death (MD), NM and other SMM. Indicators of maternal morbidity and mortality were evaluated for the three age groups. Sociodemographic, clinical and obstetric characteristics, gestational and perinatal outcomes, main causes of morbidity and delays in care were also compared. Two multiple analysis models were performed, to estimate the adjusted prevalence ratio for identified factors that were independently associated with the occurrence of severe maternal outcome (SMO = MNM + MD). RESULTS: Among SMM and MD cases identified, the proportion of adolescent girls and older women were 17% each. The risk of MNM or death was 25% higher among older women. Maternal near miss ratio and maternal mortality ratios increased with age, but these ratios were also higher among adolescents aged 10 to 14, although the absolute numbers were low. On multivariate analysis, younger age was not identified as an independent risk factor for SMO, while this was true for older age (PR 1.25; 1.07-1.45). CONCLUSIONS: SMO was high among women below 14 years of age and increased with age in Brazilian pregnant women.
