RESUMO

OBJECTIVE: To determine the agreement between five anthropometric methods used for nutritional assessment in pregnancy and to compare the distribution of nutritional status obtained with each method to that of the population of non-pregnant young women in Brazil. METHOD: This is a cross-sectional study with data from 1 108 pregnant women aged 19 to 35 years who received prenatal care from September 2011 to April 2012 in health services in the state of Pernambuco, Brazil. Nutritional status (underweight, appropriate weight, overweight/obesity) was determined using the criteria of Mardones and Rosso, Mardones et al., Atalah et al., Centro Latino Americano de Perinatologia (CLAP), and the Institute of Medicine (IOM-2009). Kappa agreement was estimated for the pairs of methods, and the chi-square goodness of fit test was performed to compare the frequency distribution of each nutritional category in each of the methods in comparison to the distribution in non-pregnant women classified according to body mass index (BMI, WHO cut-off points). RESULTS: Agreement between the methods was observed for overweight/obesity (kappa > 0.60), but not for underweight (kappa ≤ 0.60), particularly in the comparison of IOM-2009 (which relies on prepregnancy BMI) with other methods. The frequency distributions obtained with the five methods showed lower percentages of overweight/obesity and higher percentages of underweight as compared to the reference population of non-pregnant women (P < 0.001). CONCLUSION: The disparities observed in the present study may have resulted from the heterogeneity among the methods. This suggests that additional surveys are needed to establish population-specific anthropometric standards.


OBJETIVO: Verificar si hay concordancia entre cinco métodos antropométricos de clasificación nutricional de las embarazadas y comparar las clasificaciones obtenidas con la clasificación nutricional de la población brasileña de mujeres jóvenes no embarazadas. MÉTODO: Estudio transversal con datos de 1 108 embarazadas de 19 a 35 años atendidas desde septiembre del 2011 hasta abril del 2012 en servicios de atención prenatal en el estado de Pernambuco (Brasil). La clasificación nutricional (peso bajo, peso adecuado y sobrepeso u obesidad) se realizó de acuerdo con los criterios de Mardones y Rosso, de Mardones et al., de Atalah et al., del Centro Latinoamericano de Perinatología (CLAP) y del Instituto de Medicina del 2009 (IOM-2009). Se estimaron los coeficientes kappa de concordancia para los pares de métodos y la prueba del ji-cuadrado de la bondad del ajuste para comparar la distribución de frecuencias de cada categoría nutricional obtenida con cada método con la distribución en las mujeres que no están embarazadas clasificadas según el índice de masa corporal (IMC, puntos de corte de la OMS). RESULTADOS: Los métodos concordaron en lo que respecta al diagnóstico de sobrepeso y obesidad (kappa 0,60) y no concordaron en relación con el peso bajo (kappa ≤ 0,60), particularmente cuando se compararon las clasificaciones basadas en los criterios de la IOM-2009 (que utiliza el IMC pregestacional) con los demás. Las distribuciones de frecuencias muestrales obtenidas con los cinco métodos difirieron de la población de referencia de mujeres no embarazadas (P < 0,001), observándose porcentajes de sobrepeso y obesidad inferiores a la prevalencia nacional y porcentajes de peso bajo superiores a la prevalencia nacional. CONCLUSIÓN: Las disparidades observadas pueden atribuirse a la heterogeneidad de los métodos. Se justifica la realización de investigaciones para definir patrones antropométricos específicos para determinadas poblaciones.

RESUMO

BACKGROUND: Vitamin A deficiency (VAD) is a major nutritional problem in many developing countries. Vitamin A status has been reported to be adversely affected in protein-energy malnutrition (PEM). OBJECTIVE: To assess and compare serum retinol concentrations in hospitalized children with severe PEM and normal ones. METHODS: A prospective series of 34 malnourished and 29 normal control children, <60 months old, hospitalized at IMIP, Recife-PE were recruited for the study between August 2004 and May 2005. Serum retinol level was assayed by high performance liquid chromatography and concentrations adjusted for presence of inflammation as evidenced by levels of C-reactive protein. Blood retinol level was compared according to nutritional status (severe PEM versus normal), gender, age, maternal schooling, family income, breastfeeding practice, residence and perceived morbidity. RESULTS: The prevalence of low serum retinol (<0.70 micromol l(-1)) was 41.2% in children with severe PEM and 24.1% in normal children. Serum retinol concentrations were lower in children whose mothers had low schooling (p = 0.025) and families with low per capita income (p = 0.049), regardless of their nutritional status. Serum retinol concentrations had similar distribution between children with severe PEM and normal, when adjusted for gender (p > 0.05), age (p > 0.05), maternal schooling (p > 0.05), family income (p > 0.05), breastfeeding practice (p > 0.05) and residence (p > 0.05). However, malnourished children with diarrhoea showed lower serum retinol concentrations (p = 0.021) compared to those without diarrhoea. CONCLUSION: VAD was prevalent in hospitalized children with severe PEM and also among normal ones although in lesser magnitude. Intervention for prevention and control of deficiency of vitamin A are recommended in settings where diarrhea is endemic and there are unfavorable socio-economical conditions.

RESUMO

OBJECTIVE: To describe the course of migraine without aura and migraine with aura during pregnancy and factors that could influence its course, among migraine sufferers before pregnancy. METHOD: A cross sectional study undertaken at the IMIP, Brazil. Out of 686 consecutively assisted women, at the first postnatal week, 266 were identified as migraine sufferers before pregnancy. RESULTS: There was migraine remission in 35.4%, 76.8% and 79.3% among migraine without aura sufferers and 20.7%, 58.6% and 65.5% among those with migraine with aura, respectively in the first, second and third trimesters. Statistically significant difference was found when the first trimester was compared with the second and third trimesters. The factors associated with the presence of migraine during pregnancy were: multiparity, menstrually related migraine without aura prior to pregnancy and illness during pregnancy. CONCLUSION: The study contributed to elucidate the course of migraine during pregnancy in migraine sufferers prior to pregnancy.
