Ganancia de peso gestacional y su asociación con el pequeño para la edad gestacional: cohorte retrospectiva en un hospital 2000-2010(Universidad Peruana de Ciencias Aplicadas (UPC), 2015-02-04)Objective: to identify the main risk factors for term infants small for gestational age (SGA). Materials and methods: we conducted a retrospective cohort study using the database of Hospital María Auxiliadora, Lima, Peru, with information of all pregnant women during the period 2000-2010. We analyzed maternal age, parity, educational level, marital status, pre-pregnancy body mass index, number of prenatal visits (PNV), the presence of diseases such as preeclampsia, eclampsia, urinary tract infection and gestational diabetes as risk factors for SGA. The weight for gestational age was calculated on Peruvian percentiles. Crude relative risks (RR) and adjusted relative risk (aRR) with their respective confidence intervals at 95% for each variable was calculated using log binomial generalized linear models. Results: A total of 64 670 pregnant were included. The incidence of SGA was 7.2%. Preeclampsia (aRR 2.0, 95% CI: 1.86 to 2.15), eclampsia (aRR 3.22, 95% CI: 2.38 to 4.35), low maternal weight (aRR 1.38; 95% CI: 1.23 to 1.54), nulliparity (aRR 1.32; 95% CI: 1.23 to 1.42) and age ≥35 years (aRR 1.16, 95% CI: 1.04 to 1.29) were associated with an increased risk for newborn SGA. Also, a number of 0-2 PNV (aRR 1.43, 95% CI: 1.32 to 1.55), and 3-5 PNV (aRR 1.22; 95% CI: 1.14 to 1.32) were also found associated with an increased risk of newborn SGA, compared with 6-8 PNV. A number of ≥9 PNV (aRR 0.74; 95% CI: 0.69 to 0.80) was a protector factor. Conclusions: it is necessary to identify pregnant women with risk factors such as those found in this study, in order to reduce SGA. Particular emphasis on modifiable factors, such as the frequency of antenatal care visits, must be taken.Acceso abierto
La multiparidad como factor de riesgo para Diabetes Mellitus Gestacional(Universidad Peruana de Ciencias Aplicadas (UPC), 2016-02-09)Objectives: To identify risk factors for gestational diabetes mellitus (GDM). Methods: A case-control study was performed in Alberto Sabogal Hospital, collecting medical records from 2009 to 2014. A case was defined as a pregnant women diagnosed with GDM by an oral glucose tolerance test (OGTT) after an abnormal fasting glucose and control was defined as a pregnant women without GDM indicative values. The study outcome was GDM. The variables of interest were multiparity, previous cesarean section, abortions, newborn with the greatest weight. Logistic regression were used to calculate the odds ratio (OR) and a confidence interval of 95% (IC95%). Results: 84 cases and 336 controls were included. In the multivariate model, multiparity increased risk of GDM (OR= 3.54, 95% CI 1.55 to 8.14). As well history of abortions, from the second abortion (OR= 3.40, 95% CI 1.55 to 7.44) and previous cesarean section are also related (cesarean section 1 OR= 3.5 95% CI 1.89 to 6.47 and 2+ cesarean OR= 8.35 95% CI 3.50 to 19.95). Multiparity, two or more abortions, a biggest number of cesarean sections are GDM risk factors.Acceso abierto
