Estimación del acuerdo entre dos métodos para medición clínica de la edad gestacional
Grandi,Carlos;
Archivos argentinos de pediatr?-a , 2006,
Abstract: introduction. in the clinical practice, a new method frequently can only be assessed by means of its comparison against other established techniques (gold standard). the objective of the present work was to describe an approach -through graphical techniques and simple statistical calculations- to assess the agreement level between two methods for clinical measurement of gestational age and to determine if they are interchangeable. population, material and methods. this is an observational cohort study. between 2000 and 2001, 137 pregnant women were prospectively enrolled at the hospital materno-infantil ramón sardá of buenos aires before the 16th week of gestation. the last normal menstrual period and ultrasound scan measurements were used for estimating gestational age. mean difference, standard deviation and 95% confidence interval (limits of agreement) between the methods, and the mean of the two measurements were calculated and plotted for each case. results. mean gestational age at the first ultrasound scan was 19.6 (sd 4.9; 95% ci 18.7-20.4) weeks. the agreement between both methods were 71.5% (95% ci 63-78) ± 10 weeks and 82.5% (95% ci 75-87) ± 2 weeks. mean difference was 0.35 + 1.89 (95% ci 0.03-0.67) weeks and the limits of agreement showed that, independently of gestational age, differences reached 7.5 weeks. conclusions. the estimation of gestational age by the last normal menstrual period overestimated the one estimated ultrasound scan ("gold standard") by 25% and underestimated it by 20%. in the clinical practice both methods are not interchangeable.

Relación entre la antropometría materna y la ganancia de peso gestacional con el peso de nacimiento, y riesgos de peso bajo al nacer, peque?o para la edad gestacional y prematurez en una población urbana de Buenos Aires

Abstract: summary. relationship between maternal anthropometry and weight gain with birth weight, low birth weight, small for date and prematurity at an urban population of argentina. to asses the relationship between body mass index and net weight gain during pregnancy with birth weight and the risks of low birth weight, small for date and prematurity 9613 records from sardá ′s perinatal database between 1994-1995 were reviewed. exclusion criteria were fetal death, twin pregnancy, congenital malformations, lack of prenatal visits and lack of preconceptional weight and height. 9.6% of mothers and 15% of adolescents presented with low preconceptional bmi (median: 24.8 + 4.3 kg/m2); in contrast, 28% were overweight and obese. net weight gain (median 9.25+ 4.9 kg) accounted for 16% of previous weight and was higher with lower bmi (p=0.001). birth weight (median 3375 + 467 g) decreased with lower bmi (p= 0.001) and the risks of low birth weight (p < 0.05), small for date (p < 0.05), and prematurity (p= 0.05) was independently associated with bmi, and increased (p < 0.001) when lower the net weight gain was. the best predictors for low birth weight, small for date and prematurity risks were low preconceptional weight (40-51 kg) (adjusted or 1.72; [ 95%ci 1.48-1.95], 2.12 [1.82-2.41] and 1.46 [1.12-1.79] respectively). net weight gain and several predictive variables did not explain more than 10.8% of the variability of birth weight. preconceptional weight should have important implications for the design of future nutritional strategies at a poblational level, especially for adolescents

Tendencia secular del peso de nacimiento en Argentina (1992-2002): un estudio poblacional

Archivos argentinos de pediatr?-a , 2008,
Abstract: introduction. birth weight (bw) is considered an important measure of the health status of a population. objectives. 1) to assess secular trends in average bw, low birth weight (lbw,<2.500 g), very low birth weight (vlbw, < 1.500 g) and bw ≥ 3.000 g of liveborn infants in argentina; 2) calculate risks of lbw, vlbw and ≥ 3.000 g; 3) influence of underreported birth weight. material and methods. in this national-based study 7.113.931 liveborn infants born in argentina from 1992 to 2002 were included. bw was assessed from the national ministry of public health. annuals mean bw and residual distribution (rd) following the wilcox-russell approach were calculated, and also lbw, vlbw and ≥3.000 g proportions. results. a decrease of 32 g in average bw (p= 0.577) and 24 g between 2000 and 2002 (p <0.001) was observed. rd reached 4%. the significant increase in lbw (12%, p= 0.034) and vlbw (26%, p= 0.002) proportions was paralleled by a reduction of 3.6% in bw ≥3.000 g (p= 0.011, average 75.2%). risks of being lbw and vlbw were 1.13 (95% ci 1.12-1.15) and 1.30 (1.25-1.35), respectively; for bw ≥3.000 g was 0.86 (95% ci 0.85-0.87). no significant correlations between underreported bw and proportions of lbw (r= 0.10) or vlbw (r= 0.01) were observed. conclusion. a negative secular trends of bw was observed, all categories of lbw and vlbw were increased, bw > 3.000 g was diminished and under-reported bw did not influenced these results.
Estimación de la edad gestacional: Revisión de la literatura
Carlos Grandi,Fernando López
Revista del Hospital Materno Infantil Ramón Sardá , 2004,
Abstract: La estimación de la edad gestacional (EG) prenatal es un punto crítico en la toma de decisiones obstétricas así como para la evaluación pronóstica postnatal. Cuando no se tiene acceso al ultrasonido durante la primera mitad del embarazo, si la fecha de la última menstruación (FUM) es confiable y los ciclos son de 28 días, la estimación de la EG por FUM sigue siendo útil en la práctica, a pesar de presentar errores aleatorios y sistemáticos. No se ha demostrado que la estimación de la EG utilizando mediciones rutinarias por ultrasonografía precoz en poblaciones de bajo riesgo sea beneficioso para la salud materna y los resultados perinatales. La EG es sistemáticamente sobreestimada cuando se calcula únicamente por FUM, con el consiguiente sesgo de disminución de la incidencias de prematurez y aumento de la incidencia de RN de postérmino, además de disminuir la tasa de PEG. Por el contrario, una estimación por ultrasonografía disminuye el PN en cortas gestaciones y la aumenta en los embarazos de postérmino, con los consiguientes sesgos de aumento en las tasa de prematurez y disminución de los RN de postérmino. El reemplazo de la EG por FUM por la EG por US afectaría la comparación de tasas específicas de Mortalidad Infantil por Edad Gestacional y las curvas fetales de crecimiento basados en el peso para la edad gestacional, además de menos interrupciones de embarazos de pretérmino y menos inducciones por postérmino
