RESUMO

Introduction: Micronutrient deficiency is an unquestionable public health problem, specially anemia and vitamin A deficiency (VAD). This is due to the collective dimension of these carencies, which reflects on morbimortality rates in the maternal and infant group. Objective: to evaluate the impact of a proposal for prenatal nutritional assistance, comparing the prevalence of anemia and VAD, in pre-intervention (GI) and intervention(GII) groups. Methods: this is a prospective intervention study in a cohort of pregnant women. The GI group was made up of 225 the GII group of 208 pregnant adults and their respective newborns, attended a Public Maternity Wardin Rio de Janeiro, Brazil. Concentration of hemoglobin was used to diagnose anemia and a standardized interview to diagnose night blindness (XN) .Results and conclusion: after adjusting for confounding variables, through logistic regression, the protective effect of intervention at the on set of anemia (OR = 0.420;IC 95% = 0.251-0.702), with a significant reduction in prevalence, of 28.4% in the GI to 16.8% in the GII, also observed at the on set of XN (OR = 0.377; IC95% = 0.187-0.759), with a reduction in prevalence of 18.7 % in the GIto 6.2% in the GII. Nutritional intervention has a beneficial effect on maternal health, reducing nutritional deficiencies most prevalent during pregnancy and the impact of these on the obstetric ailment (AU)


Introducción: La deficiencia de micronutrientes es un problema de indudable de salud pública, especialmente la anemia y deficiencia de vitamina A (DVA). Esto es debido a la dimensión colectiva de estos carencies, que se refleja en las tasas de morbi-mortalidad en el grupo materno infantil. Objetivo: Evaluar el impacto de un proyecto de atención nutricional prenatal, comparando la prevalencia de anemia y DVA, en la pre-intervención (GI) y la intervención (GII).Métodos: se trata de una intervención prospectiva de un grupo de mujeres embarazadas. El GI consistió de 225 mujeres en el posparto y GII en 208 mujeres embarazadas y sus recién nacidos inscritos en una maternidad pública de Rio de Janeiro, Brasil. Se utilizó la concentración de hemoglobina en el diagnóstico de la anemia durante el embarazo y la entrevista estandarizada para diagnosticar la ceguera nocturna (XN). Resultados y conclusión: Tras ajustar por variables de confusión, por la regresión logística, se verificó el efecto protector de la intervención sobre la anemia (OR = 0,420,95% CI = 0.251-0.702), con reducción significativa en la prevalencia, 28,4 en el GI y 16,8% en el GII, que también se observó en los resultados XN (OR = 0,377, IC del 95%desde 0,187 hasta 0,759), con una reducción en la prevalencia, el 18,7% al 6,2% en el GI y GII. La intervención dietética tiene efectos beneficiosos sobre la salud materna, reducir las deficiencias nutricionales más prevalentes durante el embarazo y el impacto de estos sobre el resultado del embarazo (AU)

RESUMO

OBJECTIVES: This study aims to identify birth weight variation according to maternal characteristics and gestational weight gain. METHODS: It is a cross-sectional descriptive study with 433 puerperal women (> or = 20 years old) who attended a public maternity hospital in Rio de Janeiro. The data were collected through interviews with the women and access to their medical records. Several models were tested using linear regression, using the stepwise method to identify the predictive variables of birth weight. RESULTS: The mean maternal age and gestational age at the end of pregnancy were 27 years old (+/- 5.09 years) and 39 weeks (+ 1.68 weeks), respectively. The data shows that the mean number of prenatal and nutritional prenatal care appointments were 8.24 (+/- 2.98) and 2.26 (+/- 2.33), respectively. Among the predictor variables of birth weight, total gestational weight gain (beta = 25.29; p = 0.000), pre-gestational BMI (beta =13.02; p = 0.037), and the number of pre-natal care appointments (beta = 28.21; p = 0.007) were highlighted. The association of weight gain in the three trimesters was also verified. CONCLUSIONS: This study confirms the interface between adequacy of the pre-gestational and gestational nutritional status and some maternal characteristics with birth weight. Nutritional care should be recognised as part of the actions during pre-natal assistance.

Objetivo: Este estudio tiene por objeto identificar la variación de peso al nacimiento en función de las características maternas y la ganancia de peso gestacional. Métodos: Se trata de un estudio transversal y descriptivo con 433 mujeres puérperas (beta 20 años de edad) que acudieron a un hospital maternal de Río de Janeiro. Se recogieron los datos mediante entrevistas con las mujeres y acceso a sus historiales clínicos. Se ensayaron diversos modelos utilizando la regresión linear y el método por pasos para identificar las variables predictivas del peso al nacimiento. Resultados: La edad media materna y la edad gestacional al final del embarazo fueron 27 años (± 5,09 años) y 39semanas (± 1,68 semanas), respectivamente. Los datos muestran que el número medio de visitas prenatales y de educación nutricional prenatal fue de 8,24 (± 2,98) y 2,26 (± 2,33), respectivamente. Entre las variables predictivas del peso al nacimiento, destacaban la ganancia total de peso gestacional (beta= 25,29; p = 0.000), el IMC pre-gestacional(beta= 13,02; p = 0,037) y el número de visitas prenatales (beta= 28,21; p = 0,007). También se verificó la asociación de ganancia de peso en los tres trimestres del embarazo. Conclusiones: Este estudio confirma la interrelación entre un estado nutricional pre-gestacional y gestacional adecuado y algunas características maternas con el peso al nacimiento. Debería reconocerse la atención nutricional como parte de las acciones de la asistencia prenatal (AU)
