| Abstract: | Introduction: The factors involve in the intrauterine life have repercussions in the embryonic and fetal life, around the birth, and in the future life of the individual. Objective: To determine the fetal factors associated with IUGR in teenager´s children who born in the Vicente Corral Hospital in Cuenca-Ecuador during 2013. Material and methods: Case-control design; universe: newborn (NB) teens´ children born at Vicente Corral Hospital, Cuenca-Ecuador, 2013; sample: not random, cases: 116 NB with IUGR teenagers´ children, controls: 348 NB teenager´s children without IUGR. Results: The IUGR was presented more frequently in female RN (53.4%), the predominant IUGR type was asymmetrical (57.8%). The neonatal anthropometric measurements weight (p = 0.001), height (p = 0.001) and cephalic perimeter (p = 0.001) presented statistical association to the IUGR. According to the binary analysis, the fetal factors associated with IUGR were: prematurity (OR = 2.70, 95% CI = 1.17-6.20, p = 0.016) and twinness (OR = 18.93, CI = 95% 2.25-158.93, p = 0.001); fetal factors not associated with IUGR were: sex, TORCH infections, major congenital malformations (p> 0.05). According to binary logistic regression, twinness was the only one associated with IUGR (Exp B = 16.36, 95% CI = 1.92-139.64, p = 0.011). Conclusions: The IUGR was presented more frequently in the female sex, predominantly the asymmetric type. Neonatal weight, size and cephalic perimeter were associated to IUGR. The fetal factors associated to IUGR according to binary analysis were: prematurity and twinness, and binary logistic regression: twinness. |
| Resumen : | El RCIU ocupa el segundo lugar dentro de las patologías neonatales. Objetivo: determinar los factores maternos biológicos asociadas a RCIU en hijos de adolescentes nacidos en el Hospital Vicente Corral de Cuenca-Ecuador durante el año 2013. Material y métodos. Diseño de casos y controles; universo: recién nacidos (RN) hijos de adolescentes nacidos en el Hospital Vicente Corral, Cuenca-Ecuador, 2013; muestra: no probabilística, casos: 116 RN con RCIU hijos adolescentes, controles: 348 RN sin RCIU hijos de adolescentes. Resultados. Los factores maternos biológicos asociados a RCIU según el análisis binario fueron: amenaza de parto prematuro (OR 4,35; IC 95% 2,50-7,57; p 0,000), rotura prematura de membranas (OR 2,76; IC 95% 1,37-3,77; p 0,001), hipertensión arterial gestacional (OR 2,64; IC 95% 1,46-4,77; p 0,001), controles prenatales <5 (OR 2,19; IC 95% 1,39-3,47; p 0,001), incremento de peso gestacional <8 Kg (OR 2,44; IC 95% 1,37-4,36; p 0,002), IMC al inicio del embarazo <18,5 kg/m2 (OR 2,68; IC 95% 1,16-6,18; p 0,017), amenaza de aborto (OR 2,23; IC 95% 1,19-4,16; p 0,011), primer parto (OR 2,03; IC 95% 1,05-3,90; p 0,032), primer embarazo (OR 1,95; IC 95% 1,07-3,54; p 0,027), sangrado gestacional (OR 1,86; IC 95% 1,01-3,42; p 0,044). Los verdaderos factores asociados a RCIU, según regresión logística binaria, fueron: amenaza de parto prematuro (OR 9,50; IC 95% 4,10-22,01; p 0,000), hipertensión arterial gestacional (OR 6,26; IC 95% 2,37-16,51; p 0,000), sangrado gestacional (OR 2,96; IC 95% 1,23-7,10; p 0,015), incremento de peso gestacional <8 Kg (OR 2,55; IC 95% 1,26-5,16; p 0,010), peso materno al inicio de la gestación <50 Kg (OR 2,19; IC 95% 1,11-4,31; p 0,023), controles prenatales <5 (OR 2,18; IC 95% 1,05-4,55; p 0,038). Conclusiones. Los factores maternos biológicos asociados a RCIU fueron numerosos. |
