Environmental factors associated with excessive gestational weight gain: a meta-analysis and systematic review.

The aim is, systematically examine the scientific evidences that associated environmental factors (environment, social environment, environmental planning and spatial population distribution) with the excessive gestational weight gain. A meta-analysis and systematic review carried out as per the Cochrane Handbook recommendations and following the steps recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The inclusion studies were done with the following PECO criteria: P-pregnant women, E-environmental factors, O-weight gain. The search procedure was conducted on the databases EMBASE, Web of Science, Cinahl, LILACS and MEDLINE (PubMed). The relationship between the socioeconomic factors of the micro-region of residence and gestational weight gain was evidenced by the linkage between residing in high-poverty neighborhoods and inadequate gestational weight gain. This study revealed the higher prevalence of excessive gestational weight gain in pregnant women those lives in urban areas. Environmental factors of the pregnant women's residence area implicated in the excessive gestational weight gain. Our findings can therefore contribute to the development of public policies to prevent inadequate gestational weight gain.

Resumo O objetivo é examinar sistematicamente as evidências científicas que associam fatores ambientais (meio ambiente, meio ambiente social, planejamento ambiental e distribuição espacial da população) com o excessivo ganho de peso gestacional. Trata-se de uma revisão sistemática e meta-análise realizada seguindo os passos recomendados pelo Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. Os estudos de incluídos basearam-se nos seguintes critérios PECO: P-gestantes, E-fatores ambientais, O-ganho de peso gestacional. O procedimento de pesquisa foi conduzido nas bases de dados EMBASE, Web of Science, Cinahl, LILACS e MEDLINE (PubMed). A relação entre os fatores socioeconômicos da microrregião de residência e o ganho de peso gestacional foi evidenciada pela ligação entre a residência em bairros de alta pobreza e o ganho de peso gestacional inadequado. Este estudo revelou a maior prevalência de ganho de peso gestacional excessivo em gestantes que vivem em áreas urbanas. Fatores ambientais da área de residência das gestantes implicados no ganho de peso gestacional excessivo. As descobertas desse estudo podem, portanto, contribuir para o desenvolvimento de políticas públicas para evitar o ganho de peso gestacional inadequado.

Environmental and individual factors associated with gestational weight gain.

BACKGROUND: Environmental factors have an impact on inappropriate food choices and sedentary lifestyle, and both individually and in combination these factors favour improper gestational weight gain (GWG) and consequent maternal and neonatal health problems. The objective of this study was to analyze the environmental and individual factors associated with GWG. METHODS: Data were from "Born in Belo Horizonte: Survey on childbirth and birth", a hospital-based retrospective cohort of 506 pregnant women with deliveries in public and private maternity hospitals in Belo Horizonte, Minas Gerais. Data were collected via face-to-face interviews from November 2011 to March 2013. The outcome variable of this study was the GWG categorized based on the Institute of Medicine Guidelines. Explanatory environmental variables included the availability and access to food environment and places available for physical activity in the neighborhood. Explanatory individual variables included socioeconomic and demographic, obstetric and childbirth variables. Generalized estimating equations examined the association of environmental and individual factors with insufficient or excessive GWG. RESULTS: The final sample consisted of 506 mothers. There was 36.4% pregnant women showing excessive GWG and 22.7% showing GWG below the recommended interval. Regarding excessive GWG, there was a positive association with the number of mixed food purchasing establishments close to the place of residence, pre-pregnancy body mass index in the categories of overweight and obesity, arterial hypertension and the private sector as the predominant place for prenatal consultations. CONCLUSION: GWG outside of the recommended interval was associated with individual and environmental factors, and most pregnant women had insufficient or excessive gestational weight gain. Such results can complement previously published evidence, important for creating more effective strategies for the prevention of excessive and inadequate GWG and the consequent problems related to it during pregnancy.

Association between early pregnant hospitalization and use of obstetric interventions and cesarean: a cross-sectional study.

OBJECTIVE: Evaluate the association between early pregnant hospitalization and the use of obstetric interventions and cesarean delivery route. METHODS: Cross-sectional study, with 758 women selected at the time of childbirth. It was assumed as early hospitalization when the woman was admitted to the hospital having less than 6 cm of cervical dilation. Logistic regression models were constructed in order to estimate the odds ratio for each obstetric intervention, adjusted by sociodemographic and obstetric variables. RESULTS: 73.22% of women were early hospitalized. On average, they had 1.97 times the chance to undergo Kristeller's maneuver, 2.59 and 1.80 times the chance to receive oxytocin infusion and analgesia, respectively, and 8 times more chances to having their children by cesarean delivery when compared to women that had timely hospitalization. CONCLUSION: Early hospitalized women were submitted to a higher number of obstetric intervention and had increased chances of undergoing cesarean sections.

Fatores ambientais associados ao ganho de peso gestacional inadequado / Environmental factors associated with inadequate gestational weight gain

Introdução: O ganho de peso ponderal é uma das principais mudanças ocorridas durante o período gestacional e possui implicações diretas sobre a saúde materna e neonatal. Para que tal ganho seja considerado fisiológico, há um intervalo recomendado de ganho de peso para cada trimestre de gestação. O ganho de peso gestacional inadequado, excessivo ou insuficiente, pode se relacionar com desfechos negativos para mãe e criança. A influência de fatores individuais sobre o ganho de peso gestacional, em especial relacionados ao ganho de peso excessivo já está consolidada na literatura. Contudo, fatores ambientais impactam em escolhas alimentares inadequadas e no estilo de vida sedentário e, tanto individualmente quanto em combinação, estes fatores podem favorecer o ganho de peso gestacional inadequado e ter consequentes problemas de saúde materna e neonatal. Objetivo: Analisar os fatores ambientais associados ao ganho de peso gestacional inadequado. Métodos: Trata-se de uma revisão sistemática e metanálise e um estudo epidemiológico. A revisão sistemática foi conduzida segundo recomendações da Cochrane Handbook e elaborada conforme as etapas recomendadas pelo Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A estratégia de investigação foi realizada nas bases de dados EMBASE, Web of Science, Cinahl, LILACS e MEDLINE (Pubmed). A meta-análise foi realizada usando o programa livre Rstudio (versão 3.4.4) e o pacote "Metaprop". O estudo epidemiológico refere-se a uma coorte retrospectiva, desenvolvida com dados da coorte de base hospitalar "Nascer em Belo Horizonte: Inquérito sobre o parto e nascimento", na qual foram entrevistadas puérperas em maternidades públicas e privadas de Belo Horizonte, Minas Gerais (MG). De forma que coleta de dados foi realizada de novembro de 2011 a março de 2013. Foram incluídas variáveis ambientais, além de individuais - socioeconômicas, antropométricas, históricos obstétricos e relacionados ao parto. Para a análise dos dados, foi aplicado o modelo de regressão logística com Estimação de Equações Generalizadas (GEE). Resultados: Em relação à revisão sistemática, de 3936 referências recuperadas, 11 estudos preencheram a todos os critérios de inclusão. A taxa de ganho de peso gestacional excessivo variou entre 23,2 e 82,4%. Observou-se associação entre viver em bairros com maior índice de pobreza e inadequação no ganho de peso gestacional. A análise conjunta evidenciou que a maior prevalência de mulheres com ganho de peso gestacional excessivo residia em áreas urbanas, porém essa diferença não foi estatisticamente significativa (P: 51%; IC95%: 44,34-57,84). No estudo epidemiológico, a amostra foi composta por 506 gestantes residentes nos municípios de Belo Horizonte e Contagem, MG. Em relação ao índice de massa corporal (IMC) pré-gestacional, 23,52% das mulheres apresentavam obesidade e 11,07% apresentavam sobrepeso. Considerando o ganho de peso gestacional, 59,09% das gestantes tiveram ganho de peso inadequado, sendo que 36,36% apresentaram ganho excessivo e 22,73% apresentaram ganho de peso abaixo do recomendado. Com relação ao ganho de peso excessivo, observou-se associação direta com o número estabelecimentos de venda de produtos alimentícios mistos próximo ao local de residência (p=0,001), IMC pré-gestacional nas categorias de sobrepeso e obesidade (p<0,000 e p<0,000) e setor privado como local predominante de consultas de pré-natal (p=0,018). Conclusão: O ganho de peso gestacional foi influenciado por fatores individuais e ambientais, e a maioria das gestantes apresentou ganho de peso gestacional insuficiente ou excessivo. O cuidado antes e durante a gestação é, portanto, essencial para evitar inadequações no ganho de peso e consequentes desfechos negativos ao binômio.

Introduction: Weight gain is one of the main changes that occurred during pregnancy and has direct implications for maternal and newborn health. To be considered physiological, there is a recommended weight gain interval for each trimester of pregnancy. Inadequate gestational weight gain can be related to negative outcomes for mother and child. The influence of individual factors on gestational weight gain, especially related to excessive weight gain, is already consolidated in the literature. However, environmental factors impact on inappropriate food choices and sedentary lifestyle and, both individually and in combination, these factors can favor the gain of inappropriate gestational weight and have consequent maternal and neonatal health problems. Objective: To analyze the environmental factors associated with inadequate gestational weight gain. Methods: It is a systematic review and meta-analysis, and it's also an epidemiological study. The systematic review was conducted according to the recommendations of the Cochrane Handbook and elaborated according to the steps recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The search strategy was carried out in the EMBASE, Web of Science, Cinahl, LILACS and MEDLINE (Pubmed) databases. The meta-analysis was carried out using the free program Rstudio (version 3.4.4) and the package "Metaprop". The epidemiological study refers to a retrospective cohort, developed with data from the hospital-based cohort "Born in Belo Horizonte: Survey on childbirth and birth", in which postpartum women were interviewed in public and private maternity hospitals in Belo Horizonte, Minas Gerais (MG). The data collection was carried out from November 2011 to March 2013. Environmental variables were included, in addition to individual variables - socioeconomic, anthropometric, obstetric history and related to childbirth. For data analysis, the logistic regression model with Generalized Equation Estimation (GHG) was applied. Results: Regarding the systematic review, out of 3936 references retrieved, 11 studies met all the inclusion criteria. The rate of excessive gestational weight gain varied between 23.2 and 82.4%. There was an association between living in neighborhoods with a higher poverty rate and inadequate gestational weight gain. The joint analysis showed that the highest prevalence of women with excessive gestational weight gain resided in urban areas, and this difference was not statistically significant (P: 51%; 95% CI: 44.34-57.84). In the epidemiological study, the sample consisted of 506 pregnant women living in the cities of Belo Horizonte and Contagem (MG). Regarding the pre-gestational body mass index (BMI), 23.52% of women were obese and 11.07% were overweight. Considering gestational weight gain, 59.09% of pregnant women had inadequate weight gain, with 36.36% showing excessive gain and 22.73% showing weight gain below the recommended. Regarding excessive weight gain, a direct association was observed with the number of establishments selling mixed food products close to the place of residence (p = 0.001), pre-gestational BMI in the categories of overweight and obesity (p <0.000 and p < 0.000) and the private sector as the predominant place for prenatal consultations (p = 0.018). Conclusion: Gestational weight gain was influenced by individual and environmental factors, and most pregnant women had insufficient or excessive gestational weight gain. Care before and during pregnancy is essential to avoid inadequacies in weight gain and consequent negative outcomes to the binomial.

Motivo da realização de cesárea segundo relato das mães e registros de prontuários em maternidades de Belo Horizonte / Reasons for performing a cesarean section according to the puerperal women reports and the registry of medical records in maternity hospitals in Belo Horizonte / Motivos para la realización del parto por cesárea según los relatos de las madres y de los expedientes médicos de maternidades de Belo Horizonte

A alta prevalência de cirurgia cesárea é um problema de saúde pública por associar-se ao aumento da morbimortalidade materna e neonatal, principalmente quando realizada sem justificativa clínica. O presente estudo objetivou avaliar o motivo da realização da cesárea segundo os relatos da puérpera e o registro das informações no prontuário. Trata-se de estudo de coorte de base hospitalar desenvolvido com dados da pesquisa "Nascer em Belo Horizonte: inquérito sobre parto e nascimento". Comparou-se o motivo de realização da cesárea segundo relato das mães e registros em prontuários em relação à intercorrência clínica ou obstétrica durante a gestação ou parto, trabalho de parto e forma de pagamento do parto. Do total de 1.088 puérperas avaliadas, 465 tiveram a cesárea como via de nascimento e foram incluídas neste estudo. Observou-se diferença estatisticamente significativa entre os motivos da realização da cesárea relatados pela puérpera e os registrados em prontuário, o que ressalta a necessidade de rever a formação profissional e o modelo de atenção, além da necessidade de qualificação do processo de trabalho e das práticas assistenciais e do fortalecimento da autonomia das mulheres para escolhas informadas.

The high prevalence of cesarean section is a public health problem because it is associated with increased maternal and neonatal morbidity and mortality, especially when performed without clinical justification. The present study aimed to evaluate the reason for the cesarean section according to the reports of the puerperal woman and the recording of the information in the medical record. It is a hospital-based cohort study, developed with data from the research "Birth in Belo Horizonte study: survey on labor and birth". The reason for performing the cesarean section was reported according to the mothers' reports and records in medical records regarding the method of payment of labor, labor and clinical or obstetric complications during pregnancy or delivery. Of the total of 1,088 postpartum women evaluated, 465 underwent a cesarean delivery and were included in this study. A statistically significant difference was observed between the reasons for the cesarean section reported by the puerpera and those recorded in the chart, which points to the need of reviewing the professional training and the care model, besides the need to qualify the work process and the practices and empower women to make informed choices.
