Pregnancy and childbirth outcomes among adolescent mothers: A World Health Organization multicountry study

Tuvo como objetivo investigar el riesgo de resultados adversos del embarazo entre adolescentes en 29 países. El diseño utilizado fue un análisis secundario utilizando datos transversales basados en instalaciones de la Encuesta multipaís sobre salud materna y neonatal de la Organización Mundial de la Salud. Se tomó el análisis de veintinueve países de África, América Latina, Asia y Oriente Medio. La población estimada fue de mujeres ingresadas para el parto de 359 centros de salud durante 2 a 4 meses entre 2010 y 2011. Se utilizaron modelos de regresión logística multinivel para estimar la asociación entre la edad materna joven y los resultados adversos del embarazo. Se analizaron un total de 124 446 madres de ≤24 años y sus bebés. En comparación con las madres de 20 a 24 años, las madres adolescentes de 10 a 19 años tenían mayores riesgos de eclampsia, endometritis puerperal, infecciones sistémicas, bajo peso al nacer, parto prematuro y afecciones neonatales graves. El mayor riesgo de muerte neonatal temprana intrahospitalaria entre los bebés nacidos de madres adolescentes se redujo y fue estadísticamente insignificante después del ajuste por edad gestacional y peso al nacer, además de las características maternas, el modo de parto y la malformación congénita. La cobertura de los uterotónicos profilácticos, los antibióticos profilácticos para la cesárea y los corticosteroides prenatales para el parto prematuro a las 26 - 34 semanas fue significativamente menor entre las madres adolescentes. El embarazo adolescente se asoció con mayores riesgos de resultados adversos del embarazo. Las estrategias de prevención del embarazo y la mejora de las intervenciones de atención médica son cruciales para reducir los resultados adversos del embarazo entre las mujeres adolescentes en países de bajos y medianos ingresos

Risk factors and adverse perinatal outcomes among term and preterm infants born small-for-gestational-age: secondary analyses of the WHO multi-country survey on maternal and newborn health

BACKGROUND Small for gestational age (SGA) is not only a major indicator of perinatal mortality and morbidity, but also the morbidity risks in later in life. We aim to estimate the association between the birth of SGA infants and the risk factors and adverse perinatal outcomes among twenty-nine countries in Africa, Latin America, the Middle East and Asia in 359 health facilities in 2010–11. METHODS We analysed facility-based, cross-sectional data from the WHO Multi-country Survey on Maternal and Newborn Health. We constructed multilevel logistic regression models with random effects for facilities and countries to estimate the risk factors for SGA infants using country-specific birthweight reference standards in preterm and term delivery, and SGA’s association with adverse perinatal outcomes. We compared the risks and adverse perinatal outcomes with appropriate for gestational age (AGA) infants categorized by preterm and term delivery. RESULTS A total of 295,829 singleton infants delivered were analysed. The overall prevalence of SGA was highest in Cambodia (18.8%), Nepal (17.9%), the Occupied Palestinian Territory (16.1%), and Japan (16.0%), while the lowest was observed in Afghanistan (4.8%), Uganda (6.6%) and Thailand (9.7%). The risk of preterm SGA infants was significantly higher among nulliparous mothers and mothers with chronic hypertension and preeclampsia/eclampsia (aOR: 2.89; 95% CI: 2.55–3.28) compared with AGA infants. Higher risks of term SGA were observed among sociodemographic factors and women with preeclampsia/eclampsia, anaemia and other medical conditions. Multiparity (> = 3) (AOR: 0.88; 95% CI: 0.83–0.92) was a protective factor for term SGA. The risk of perinatal mortality was significantly higher in preterm SGA deliveries in low to high HDI countries. CONCLUSION Preterm SGA is associated with medical conditions related to preeclampsia, but not with sociodemographic status. Term SGA is associated with sociodemographic status and various medical conditions.Erika Ota, Togoobaatar Ganchimeg, Naho Morisaki, Joshua P. Vogel, Cynthia Pileggi, Eduardo Ortiz-Panozo, Joa, o P.

Exploratory analysis of the ecological variables associated with sexual health profiles in high-risk, sexually-active female learners in rural KwaZulu-Natal

Young women are at high risk for negative sexual health outcomes. Despite their high risk, many sexually-active women never experience negative sexual health outcomes. This study explored the ecological risk factors associated with the risk profiles of sexually-active female high school-learners in rural KwaZulu-Natal, South Africa

Prevalence of early initiation of breastfeeding and determinants of delayed initiation of breastfeeding: secondary analysis of the WHO Global Survey

Early initiation of breastfeeding (EIBF) within 1 hour of birth can decrease neonatal death. However, the prevalence of EIBF is approximately 50% in many developing countries, and data remains unavailable for some countries. We conducted a secondary analysis using the WHO Global Survey on Maternal and Perinatal Health to identify factors hampering EIBF. We described the coverage of EIBF among 373 health facilities for singleton neonates for whom breastfeeding was initiated after birth. Maternal and facility characteristics of EIBF were compared to those of breastfeeding >1 hour after birth, and multiple logistic regression analysis was performed. In total, 244,569 singleton live births without severe adverse outcomes were analysed. The EIBF prevalence varied widely among countries and ranged from 17.7% to 98.4% (average, 57.6%). There was less intra-country variation for BFI <24 hours. After adjustment, EIBF was significantly lower among women with complications during pregnancy and caesarean delivery. Globally, EIBF varied considerably across countries. Maternal complications during pregnancy, caesarean delivery and absence of postnatal/neonatal care guidelines at hospitals may affect EIBF. Our findings suggest that to better promote EIBF, special support for breastfeeding promotion is needed for women with complications during pregnancy and those who deliver by caesarean section
