Condições de moradia como determinante social de baixo peso ao nascer e prematuro de baixo peso

OBJECTIVE: To assess the relationship between housing conditions and low birthweight and preterm low birthweight among low-income women. METHODS: A case-control study was conducted with post-partum women living in the city of Rio de Janeiro, Southeast Brazil, in 2003-2005. Two groups of cases, low birthweight (n=96) and preterm low birthweight infants (n=68), were compared against normal weight term controls (n=393). Housing conditions were categorized into three levels: adequate, inadequate, and highly inadequate. Covariates included sociodemographic and anthropometric characteristics, risk behaviors, violence, anxiety, satisfaction during pregnancy, obstetric history and prenatal care. RESULTS: Poor housing conditions was independently associated with low birthweight (inadequate - OR 2.3 [1.1;4.6]; highly inadequate - OR 7.6 [2.1;27.6]) and preterm low birthweight (inadequate - OR 2.2 [1.1;4.3]; highly inadequate - OR 7.6 [2.4;23.9]) and factors associated with outcomes were inadequate prenatal care and previous preterm birth. Low income and low maternal body mass index remained associated with low birthweight. CONCLUSIONS: Poor housing conditions were associated with low birthweight and preterm low birthweight.OBJETIVO: Evaluar la relación entre condiciones de vivienda y bajo peso al nacer y prematuridad asociada al bajo peso al nacer en los hijos de mujeres de baja renta. MÉTODOS: Se realizó estudio caso-control con mujeres en el postparto residentes en el municipio de Rio de Janeiro, Sureste de Brasil, en 2003-2005. Dos grupos de casos fueron comparados con controles a término y con peso normal (n=393): bajo peso al nacer (n=96) y prematuridad asociada al bajo peso al nacer (n=68). Las condiciones de vivienda fueron consideradas en los niveles: adecuadas, inadecuadas y muy inadecuadas. Las covariables investigadas fueron características sociodemográficas, antropométricas, hábitos de riesgo, violencia, ansiedad, satisfacción con el embarazo, historia obstétrica y cuidados prenatales. RESULTADOS: Condiciones de vivienda inadecuadas fueron independientemente asociadas con bajo peso al nacer (Inadecuadas - OR= 2,3 (1,1;4,6) y muy inadecuadas - OR=7,6 (2,1;27,6) y con prematuridad asociada al bajo peso al nacer (inadecuadas - OR=2,2 (1,1;4,3) y muy inadecuadas - OR=7,6 (2,4;23,9). Factores asociados con los resultados incluyeron cuidados prenatales inadecuados y prematuridad previa. Baja renta y bajo índice de masa corporal materno fueron asociados con bajo peso al nacer. CONCLUSIONES: Condiciones de vivienda inadecuadas fueron asociadas con bajo peso al nacer y prematuridad asociada al bajo peso al nacer.OBJETIVO: Avaliar a relação entre condições de moradia e baixo peso ao nascer e prematuridade associada ao baixo peso ao nascer nos filhos de mulheres de baixa renda. MÉTODOS: Foi realizado estudo caso-controle com mulheres no pós-parto residentes no município do Rio de Janeiro, RJ, em 2003-2005. Dois grupos de casos foram comparados com controles a termo e com peso normal (n = 393): baixo peso ao nascer (n = 96) e prematuridade associada ao baixo peso ao nascer (n = 68). As condições de moradia foram consideradas nos níveis: adequadas, inadequadas e muito inadequadas. As covariáveis investigadas foram características sociodemográficas, antropométricas, hábitos de risco, violência, ansiedade, satisfação com a gravidez, história obstétrica e cuidados pré-natais. RESULTADOS: Condições de moradia inadequadas foram independentemente associadas com baixo peso ao nascer (Inadequadas - OR = 2,3 (1,1;4,6) e muito inadequadas - OR = 7,6 (2,1;27,6) e com prematuridade associada ao baixo peso ao nascer (inadequadas - OR = 2,2 (1,1;4,3) e muito inadequadas - OR = 7,6 (2,4;23,9). Fatores associados com os desfechos incluíram cuidados pré-natais inadequados e prematuridade prévia. Baixa renda e baixo índice de massa corporal materno foram associados com baixo peso ao nascer. CONCLUSÕES: Condições de moradia inadequadas foram associadas com baixo peso ao nascer e prematuridade associada ao baixo peso ao nascer

Rio de Janeiro, RJ, Brasil.Background: Maternal near-miss (MNM) audits are considered a useful approach to improving maternal healthcare. The aim of this study was to evaluate the factors associated with maternal near-miss cases in childbirth and the postpartum period in Brazil. Methods: The study is based on data from a nationwide hospital-based survey of 23,894 women conducted in 2011–2012. The data are from interviews with mothers during the postpartum period and from hospital medical files. Univariate and multivariable logistic regressions were performed to analyze factors associated with MNM, including estimation of crude and adjusted odds ratios and their respective 95 % confidence intervals (95 % CI). Results: The estimated incidence of MNM was 10.2/1,000 live births (95 % CI: 7.5–13.7). In the adjusted analyses, MNM was associated with the absence of antenatal care (OR: 4.65; 95 % CI: 1.51–14.31), search for two or more services before admission to delivery care (OR: 4.49; 95 % CI: 2.12–9.52), obstetric complications (OR: 9.29; 95 % CI: 6.69–12.90), and type of birth: elective C-section (OR: 2.54; 95 % CI: 1.67–3.88) and forceps (OR: 9.37; 95 % CI: 4.01–21.91). Social and demographic maternal characteristics were not associated with MNM, although women who self-reported as white and women with higher schooling had better access to antenatal and maternity care services. Conclusion: The high proportion of elective C-sections performed among women in better social and economic situations in Brazil is likely attenuating the benefits that could be realized from improved prenatal care and greater access to maternity services. Strategies for reducing the rate of MNM in Brazil should focus on: 1) increasing access to prenatal care and delivery care, particularly among women who are at greater social and economic risk and 2) reducing the rate of elective cesarean section, particularly among women who receive services at private maternity facilities, where C-section rates reach 90 % of births
