Preterm delivery and immigration

Prematurity is the main cause of perinatal morbidity and mortality. There are many and varied risk factors described: some related to the mother, such as age, parity, socioeconomic situation, lifestyles or obstetric history; others related to pregnancy, such as prenatal care received or gestational complications. Many of them can be found among immigrant women residing in Spain, but the literature is limited. A cross-sectional study is proposed with the objective of identifying the prematurity rate and related factors in a population of immigrant and native women. To do this, the records of 1,874 immigrant women who gave birth at the Hospital of El Ejido (Almería) between January 1997 and June 2003 are exploited, and compared with an equal group of native women, whose birth was immediately afterwards. It was observed that, although the percentage of premature newborns in immigrant women was somewhat higher than in Spanish women (7.31% vs. 6.72%), this difference was not significant. On the other hand, among immigrant women with premature children, a greater history of sexually transmitted infections, hypertensive disease, and inadequate prenatal care was observed (p<0.05).La prematuridad es la principal causa de morbimortalidad perinatal. Son muchos y variados los factores de riesgo descritos: unos relacionados con la madre, como la edad, paridad, situación socioeconómica, estilos de vida o antecedentes obstétricos; otros relacionados con el embarazo, como la atención prenatal recibida o las complicaciones gestacionales. Muchos de ellos pueden encontrarse entre las mujeres inmigrantes que residen en España, pero la literatura es limitada. Se plantea un estudio transversal con el objetivo de identificar la tasa de prematuridad y los factores relacionados en una población de mujeres inmigrantes y autóctonas. Para ello, se explotan los registros de 1.874 mujeres inmigrantes que dieron a luz en el Hospital de El Ejido (Almería) entre Enero de 1997 a Junio de 2003, y se compara con un grupo igual de mujeres autóctonas, cuyo parto fue inmediatamente posterior. Se observó que, aunque el porcentaje de recién nacidos prematuros en mujeres inmigrantes fue algo superior a las españolas (7,31% vs. 6,72%), esta diferencia no fue significativa. Por otro lado, entre las mujeres inmigrantes con hijos prematuros, se observó más antecedentes de infecciones de transmisión sexual, enfermedad hipertensiva, y control prenatal inadecuado (p<0,05)

Walking in pregnancy and prevention of insomnia in third trimester using pedometers: study protocol of Walking_Preg project (WPP). A randomized controlled trial

Background: Previous studies in pregnancy have not focused in evaluating the effect of walking during pregnancy and prevention of insomnia. Our general objective is to determine the effect of a walking program in preventing the appearance of insomnia in the third trimester of pregnancy, increasing sleep quality and improving quality of life throughout pregnancy. Methods: Randomized Controlled trial in parallel in healthy sedentary pregnant women (n = 265), Walking_Preg Project (WPP), from university hospital in Granada, Spain. At 12th gestational week (GW), they will be invited to participate and randomly assigned to one of the three arms of study: the intervention group I1 (pedometer, goal of 11,000 steps/day), intervention group I2 (pedometer, no goal) and control (no pedometer). Duration of intervention: 13–32 GW. At 12th, 19th and 31st GW the average steps/day will be measured in groups I1 and I2. At 13th, 20th and 32nd GW, Athens Insomnia Scale (AIS), Pittsburgh Sleep Quality Index (PSQI), Adherence to Mediterranean Diet (AMD), physical activity (short IPAQ), quality of life (PSI), and consumption of toxic substances (caffeine, illegal drugs, alcohol and tobacco) will be collected. Student t test or Mann-Whitney U will be used to compare 19th and 31st GW mean of daily steps between I1 and I2 groups. To compare differences between groups in terms of frequency of insomnia/quality of life for each trimester of pregnancy, Pearson’s Chi-square test or Fisher’s exact test will be used. To determine differences in hours of sleep and quality of sleep throughout each trimester of pregnancy, analysis of variance or Friedman test will be used. McNemar-Bowker test will be used to assess differences in life quality in pre-post analyses in the 3 arms. We will use Stata 15 statistical software.Fundacion Publica Andaluza para la Investigacion Biosanitaria (FIBAO - IBS) PI-0350-201
