Birth defects in newborns and stillborns: an example of the Brazilian reality

<p>Abstract</p> <p>Background</p> <p>This study constitutes a clinical and genetic study of all newborn and stillborn infants with birth defects seen in a period of one year in a medical school hospital located in Brazil. The aims of this study were to estimate the incidence, causes and consequences of the defects.</p> <p>Methods</p> <p>For all infants we carried out physical assessment, photographic records, analysis of medical records and collection of additional information with the family, besides the karyotypic analysis or molecular tests in indicated cases.</p> <p>Result</p> <p>The incidence of birth defects was 2.8%. Among them, the etiology was identified in 73.6% (ci95%: 64.4-81.6%). Etiology involving the participation of genetic factors single or associated with environmental factors) was more frequent 94.5%, ci95%: 88.5-98.0%) than those caused exclusively by environmental factors (alcohol in and gestational diabetes mellitus). The conclusive or presumed diagnosis was possible in 85% of the cases. Among them, the isolated congenital heart disease (9.5%) and Down syndrome (9.5%) were the most common, followed by gastroschisis (8.4%), neural tube defects (7.4%) and clubfoot (5.3%). Maternal age, parental consanguinity, exposure to teratogenic agents and family susceptibility were some of the identified risk factors. The most common observed consequences were prolonged hospital stays and death.</p> <p>Conclusions</p> <p>The current incidence of birth defects among newborns and stillbirths of in our population is similar to those obtained by other studies performed in Brazil and in other underdeveloped countries. Birth defects are one of the major causes leading to lost years of potential life. The study of birth defects in underdeveloped countries should continue. The identification of incidence, risk factors and consequences are essential for planning preventive measures and effective treatments.</p

Resultados perinatais em gestações tardias

O objetivo do estudo foi comparar resultados perinatais de mulheres com idade igual ou superior a 35 anos com os de mulheres entre 20 e 34 anos. O estudo é retrospectivo e foi realizado a partir da consulta às fichas obstétricas de 1.255 puérperas que tiveram partos no único hospital de Sarandi-PR, no período de janeiro de 2007 a dezembro de 2008. As variáveis analisadas foram: estado civil, escolaridade, idade gestacional, tipo de parto, peso ao nascer, índice de Apgar no 1º e 5º minutos e óbitos fetais. Na regressão logística, a idade materna avançada esteve associada significativamente à cesariana (OR 1,23, IC 95% 0,19-0,44) e a um índice de Apgar menor que 7 no 5º minuto de vida (OR 5,78, IC 95% 0,74-2,76). Esses resultados evidenciam os riscos de complicações em gestantes com idade igual ou superior a 35 anos e a necessidade de que o aconselhamento às mulheres que pretendam postergar a gestação seja realizado

The experiences of pregnant women at an advanced maternal age: an integrative review

Abstract OBJECTIVE To identify in the literature how the experiences of women age 35 or above are described in terms of pregnancy. METHOD Integrative review based on MEDLINE/PubMed, CINAHL, LILACS, and SciELO databases, with no time period constraint. RESULTS Eighteen studies that dealt with the experiences of pregnant women at an advanced maternal age were selected and analyzed. The studies evidenced four theme categories: the search for information, which pointed to a deficit of information supplied by health care professionals; perceiving the risks, which pointed to women's concerns about their own health and their children's; the ideal moment for motherhood, with different reasons for postponing it; and adjusting to a new routine, showing a concern regarding changes in daily life. CONCLUSION From the results, it was possible to understand that other factors, in addition to those that include risks, are present in the experiences of older pregnant women and point to a need to involve such aspects in nursing care to create comprehensive strategies that are aligned with these women's needs

Estado nutricional pré-gestacional, ganho de peso materno, condições da assistência pré-natal e desfechos perinatais adversos entre puérperas adolescentes Pre-pregnancy nutritional status, maternal weight gain, prenatal care, and adverse perinatal outcomes among adolescent mothers

OBJETIVO: Identificar associação entre estado nutricional pré-gestacional, ganho ponderal materno e condições do pré-natal com os desfechos prematuridade e baixo peso ao nascer (BPN) em filhos de mães adolescentes. MÉTODOS: Estudo transversal com 542 pares de puérperas adolescentes e conceptos atendidos em uma maternidade pública do município do Rio de Janeiro (RJ). Os dados foram coletados em prontuários. Para verificar a associação entre as variáveis independentes e os desfechos estudados, foram estimados a odds ratio (OR) e o intervalo de confiança (IC) de 95%. RESULTADOS: Quanto ao estado nutricional pré-gestacional das adolescentes, 87% apresentavam eutrofia, 1% baixo peso, 10% sobrepeso e 2% obesidade. A inadequação do ganho de peso gestacional total (72%) superou a adequação (28%). O peso ao nascer foi favorecido com maior ganho de peso gestacional e reduzido com início tardio do pré-natal (PN). A comparação entre os grupos de conceptos com baixo peso e com peso adequado ao nascer revelou diferenças significativas entre as médias das variáveis: intervalo entre a última gestação e a atual (p = 0,022); peso pré-gestacional (p = 0,018); índice de massa corporal pré-gestacional (p < 0,001) e ganho de peso gestacional total (p = 0,047). As chances de BPN (OR 2,70; IC 95% 1,45 - 5,06) e de prematuridade (OR 5,82; IC 95% 3,10 - 10,92) reduziram quando a adolescente recebeu 6 ou mais consultas de PN. CONCLUSÃO: O peso ao nascer foi relacionado ao intervalo intergestacional, ao peso pré-gestacional e ao índice de massa corporal pré-gestacional. A frequência mínima de 6 consultas de assistência pré-natal constituiu-se em fator de proteção contra o BPN e a prematuridade.<br>OBJECTIVE: To identify the association between pre-gestational nutritional status, maternal weight gain, and prenatal care with low birth weight (LBW) and prematurity outcomes in infants of adolescent mothers. METHODS: Cross-sectional study with 542 pairs of adolescent mothers and their children attending a public maternity hospital in Rio de Janeiro. Data were collected from medical records. To determine the association between independent variables and the outcomes studied, odds ratio (OR) and a 95% confidence interval (CI) were estimated RESULTS: With respect to pre-pregnancy nutritional status of adolescents, 87% had normal weight, 1% were underweight, 10% were overweight, and 2% obese. Inadequate total gestational weight gain (72%) exceeded adequacy (28%). Birth weight was favored with greater gestational weight gain, and reduced with late onset of prenatal care. The comparison between the low birth weight and normal birth weight groups revealed significant differences between variable means: interval between the past pregnancy and current pregnancy (p = 0.022), pre-gestational weight (p = 0.018); pre-gestational body mass index (p < 0.001), and total gestational weight gain (p = 0.047). The odds of LBW (OR 2.70, 95% CI 1.45 to 5.06) and prematurity (OR 5.82, 95% CI 3.10 to 10.92) fell when the adolescent received six or more prenatal visits. CONCLUSION: Birth weight was associated with inter-gestational interval, pre-pregnancy weight and body mass index before pregnancy. The minimum frequency of six prenatal care visits was a protective factor against LBW and prematurity

Dietary patterns in pregnancy and birth weight

<div><p>OBJECTIVE To analyze if dietary patterns during the third gestational trimester are associated with birth weight.METHODS Longitudinal study conducted in the cities of Petropolis and Queimados, Rio de Janeiro (RJ), Southeastern Brazil, between 2007 and 2008. We analyzed data from the first and second follow-up wave of a prospective cohort. Food consumption of 1,298 pregnant women was assessed using a semi-quantitative questionnaire about food frequency. Dietary patterns were obtained by exploratory factor analysis, using the Varimax rotation method. We also applied the multivariate linear regression model to estimate the association between food consumption patterns and birth weight.RESULTS Four patterns of consumption – which explain 36.4% of the variability – were identified and divided as follows: (1) prudent pattern (milk, yogurt, cheese, fruit and fresh-fruit juice, cracker, and chicken/beef/fish/liver), which explained 14.9% of the consumption; (2) traditional pattern, consisting of beans, rice, vegetables, breads, butter/margarine and sugar, which explained 8.8% of the variation in consumption; (3) Western pattern (potato/cassava/yams, macaroni, flour/farofa/grits, pizza/hamburger/deep fried pastries, soft drinks/cool drinks and pork/sausages/egg), which accounts for 6.9% of the variance; and (4) snack pattern (sandwich cookie, salty snacks, chocolate, and chocolate drink mix), which explains 5.7% of the consumption variability. The snack dietary pattern was positively associated with birth weight (β = 56.64; p = 0.04) in pregnant adolescents.CONCLUSIONS For pregnant adolescents, the greater the adherence to snack pattern during pregnancy, the greater the baby’s birth weight.</p></div
