RESUMEN

The association between the quality of maternal dietary fat intake during pregnancy and the infant's birthweight (BW) remains controversial. Our goal was to investigate the association between maternal dietary fat intake during pregnancy and the rate of large for gestational age (LGA) newborns. This study employed a cross-sectional analysis of 297 pairs of mothers/children attending a public maternity at Rio de Janeiro, Brazil. BW for gestational age according to the Intergrowth 21st was defined as follows: adequate for gestational age (AGA ≤ 90th percentile) and LGA (>90th percentile). The statistical analysis was a Poisson regression with robust estimations of the standard errors. Maternal dietary fat intake variables comprised lipids (% total energy); saturated (mg/1000 kcal), monounsaturated (mg/1000 kcal) and polyunsaturated (mg/1000 kcal) fats; and cholesterol (mg/1000 kcal), all of which were obtained with a Food Frequency Questionnaire. The mean BW was 3338 g (SD = 446.9), and the rate of LGA newborns was 13.1%. The mean maternal total energy intake was 2880 kcal (SD = 1074), cholesterol was 154.3 mg/1000 kcal (SD = 68.1) and monounsaturated fat was 6.9 mg/1000 kcal (SD = 2). Mothers of LGA newborns reported higher cholesterol dietary intake (195.8 vs. 148 mg/1000 kcal; P < 0.001), pre-pregnancy body mass index (25.1 vs. 23.5 kg/m2 ; P = 0.026) when compared with mothers of AGA newborns. Women with cholesterol intake within the fourth quartile were 2.48 (95% confidence interval: 1.31-4.66) times more likely to have an LGA infant compared with those in the 1-3 quartiles. Dietary intake of cholesterol during pregnancy influences LGA even after adjusting for other confounders.

RESUMEN

SUMMARY Introduction: To assess dietary habits, nutritional status and food frequency in children and adolescents with Down syndrome (DS) and congenital heart disease (CHD). Additionally, we attempted to compare body mass index (BMI) classifications according to the World Health Organization (WHO) curves and curves developed for individuals with DS. Method: Cross-sectional study including individuals with DS and CHD treated at a referral center for cardiology, aged 2 to 18 years. Weight, height, BMI, total energy and food frequency were measured. Nutritional status was assessed using BMI for age and gender, using curves for evaluation of patients with DS and those set by the WHO. Results: 68 subjects with DS and CHD were evaluated. Atrioventricular septal defect (AVSD) was the most common heart disease (52.9%). There were differences in BMI classification between the curves proposed for patients with DS and those proposed by the WHO. There was an association between consumption of vitamin E and polyunsaturated fatty acids. Conclusion: Results showed that individuals with DS are mostly considered normal weight for age, when evaluated using specific curves for DS. Reviews on specific curves for DS would be the recommended practice for health professionals so as to avoid precipitated diagnosis of overweight and/or obesity in this population.


RESUMO Objetivo: avaliar hábitos alimentares, estado nutricional e frequência alimentar em crianças e adolescentes com síndrome de Down (SD) portadores de cardiopatia congênita (CC). Adicionalmente, procurou-se comparar classificações de índice de massa corpórea (IMC) de acordo com curvas da Organização Mundial da Saúde (OMS) e curvas desenvolvidas para indivíduos com SD. Método: estudo transversal com indivíduos portadores de SD e CC atendidos em um centro de referência para cardiologia, com idade entre 2 e 18 anos. Foram aferidos peso, altura, IMC, valor energético total (VET) e frequência alimentar. O estado nutricional foi analisado por meio de IMC para gênero e idade, utilizando-se curvas específicas para SD e curvas da OMS. Resultados: foram avaliados 68 indivíduos portadores de SD com CC. O defeito do septo atrioventricular (DSAV) foi a cardiopatia mais frequente (52,9%). Houve diferença de classificação do IMC entre as curvas propostas para portadores de SD e pela OMS. Houve associação entre consumo de vitamina E e ácidos graxos poli-insaturados. Conclusão: resultados mostraram que indivíduos com SD são, em sua maioria, considerados eutróficos para a idade quando avaliados pelas curvas específicas para SD. Avaliá-los de acordo com as curvas específicas para SD seria o recomendado para a prática dos profissionais da saúde, evitando-se diagnósticos precipitados de sobrepeso e/ou obesidade nessa população.

RESUMEN

Summary Objective: To investigate the prevalence of overweight, abdominal obesity and associated factors in people living with HIV/AIDS (PLWHA). Method: Cross-sectional study with 270 PLWHA. A questionnaire was applied to investigate sociodemographic, clinical and lifestyle characteristics. Weight, height and waist circumference were measured. BMI ≥25 kg/m2 was considered overweight, while abdominal obesity referred to waist circumference ≥102 cm for men and ≥88 cm for women. The authors used multiple Poisson regression with 5% significance level. Results: The prevalence of overweight and abdominal obesity was 33.7% and 12.6%, respectively, referring to 37.9% of women and 5.7% of men (p<0.001). Overweight was associated with age of 40-49 years and ≥50 years, non-use of ARV therapy, and lower tertile of consumption of risk foods. Abdominal obesity was associated with: female gender, age of 40-49 years and ≥50 years, income greater than four times the minimum wage, and CD4+ lymphocyte count >350 cells/mm3. Conclusion: There was a high prevalence of overweight and abdominal obesity associated with sociodemographic and clinical conditions, and consumption of risk foods. This scenario indicates the need for reorientation of the health care focus in this population.


Resumo Objetivo: investigar em pessoas vivendo com HIV/aids (PVHA) a prevalência de excesso de peso, obesidade abdominal e fatores associados. Método: estudo transversal com 270 PVHA. Aplicou-se questionário para investigar características sociodemográficas, clínicas e estilo de vida. Coletaram-se peso, altura e circunferência de cintura. Consideraram-se excesso de peso o IMC ≥25 kg/m2 e obesidade abdominal a circunferência de cintura ≥102 cm para homens e ≥88 cm para mulheres. Utilizou-se regressão de Poisson múltipla com nível de significância de 5%. Resultados: a prevalência de excesso de peso foi de 33,7% e de obesidade abdominal foi de 12,6%, sendo 37,9% nas mulheres e 5,7% nos homens (p<0,001). Excesso de peso foi associado com idade de 40 a 49 anos e ≥50 anos, não uso de terapia antirretroviral (TARV) e menor tercil de consumo de alimentos de risco. Obesidade abdominal se associou com sexo feminino, idade de 40 a 49 anos e ≥50 anos, renda própria maior que quatros salários mínimos e contagem de linfócitos T CD4+ >350 células/mm3. Conclusão: constatou-se elevada prevalência de excesso de peso e obesidade abdominal, associados a condições sociodemográficas, clínicas e consumo de alimentos de risco. Esse panorama sinaliza a necessidade de reorientação do foco de atenção à saúde dessa população.

RESUMEN

Anthropometric indicators play an important role in the health status assessment of individuals and populations across the different vulnerable groups, due to which it is necessary to ascertain the percentile distribution of the weight, body mass index (BMI), and mid-arm, thigh, and calf circumferences in pregnant women for each week of gestational age. This descriptive and cross-sectional study included 4,481 measurements of anthropometric variables obtained from 745 pregnancies out of 719 subjects aged between 19 and 39 years, who were well-nourished, healthy, without clinical edema in the third trimester, with single pregnancy, and validated gestational age. All evaluations were conducted at the Centro de Atención Nutricional Infantil Antímano, CANIA, from 1998 to 2012. The anthropometric measurements were performed by standardized anthropometrists. Measures of central tendency and dispersion, bivariate correlations, and percentiles 3, 10, 25, 50, 75, 90, and 97 were calculated for each gestational age, between the 8th and 37th weeks of gestation. The number of measurements performed for each studied variable ranged from a minimum of 101 and a maximum of 241 at each gestational week. The BMI and circumference behaviors showed increases as the gestational age advanced. The changes in the variables observed in the 50th percentile between weeks 8 thru 37 were: weight, 10.10 kg; BMI, 4.23 kg/m2; and circumferences (cm): mid-arm, 0.45; calf, 1.60; and thigh, 3.55. The results of this study provide the means to simplify the screening and follow-up of the nutritional status in an accurate manner at any stage of gestation until the 37th week.


Los indicadores antropométricos juegan un papel importante en la evaluación el estado de salud a nivel individual y poblacional en los diferentes grupos vulnerables por lo que resulta necesario conocer la distribución percentilar del peso, índice de masa corporal (IMC) y circunferencias: media del brazo, muslo y pierna, para cada edad gestacional. Estudio descriptivo, de corte transversal, incluyó 4484 mediciones de las variables antropométricas obtenidas de 745 embarazos, provenientes de 719 mujeres, con edades comprendidas entre 19 y 39 años, sanas, eutróficas, sin edema, con embarazo simple y edad gestacional validada, evaluadas en el Centro de Atención Nutricional Infantil Antímano, desde 1998 hasta el 2012. Las mediciones antropométricas fueron realizadas por antropometristas estandarizadas. Se calcularon medidas de tendencia central y de dispersión, así como correlaciones bivariantes y percentiles 3, 10, 25, 50, 75, 90 y 97 para cada edad gestacional, entre las 8 y 37 semanas de gestación. El número de mediciones realizadas para cada variable analizada varió entre 101 y 241 por edad gestacional. El comportamiento del IMC y circunferencias evidenció incrementos a medida que aumenta la edad gestacional. Los cambios referidos al percentil 50 de las variables, de las semanas de gestación 8 a la 37 fueron: peso 10,10 kg; IMC 4,23 Kg/m2; circunferencias (cm): media del brazo 0,45; pierna 1,60; muslo 3,55. Los resultados de este estudio constituyen una herramienta que simplifica la evaluacion inicial y el seguimiento del estado nutricional de manera puntual en cualquier momento de la gestacion hasta las 37 semanas de edad gestacional.

RESUMEN

Protein-energy malnutrition (PEM) is a treatable disease with high prevalence among hospitalized patients. It can cause significant increases in the duration of hospitalization and costs. PEM is especially important for health systems since malnourished patients present higher morbidity and mortality. The objective of the present study was to assess the evolution of nutritional status (NS) and the effect of malnutrition on clinical outcome of patients at a public university hospital of high complexity in Brazil. Patients hospitalized in internal medicine (n = 54), oncology (n = 43), and infectious diseases (n = 12) wards were included. NS was evaluated using subjective global assessment up to 48 h after admission, and thereafter at intervals of 4-6 days. On admission, patients (n = 109) were classified as well-nourished (n = 73), moderately malnourished or at risk of malnutrition (n = 28), and severely malnourished (n = 8). During hospitalization, malnutrition developed or worsened in 11 patients. Malnutrition was included in the clinical diagnosis of only 5/36 records (13.9% of the cases, P = 0.000). Nutritional therapy was administered to only 22/36 of the malnourished patients; however, unexpectedly, 6/73 well-nourished patients also received commercial enteral diets. Complications were diagnosed in 28/36 malnourished and 9/73 well-nourished patients (P = 0.000). Death occurred in 12/36 malnourished and 3/73 well-nourished patients (P = 0.001). A total of 24/36 malnourished patients were discharged regardless of NS. In summary, malnutrition remains a real problem, often unrecognized, unappreciated, and only sporadically treated, even though its effects can be detrimental to the clinical course and prognosis of patients. The amount of public and private funds unnecessarily dispersed because of hospital malnutrition is significant.
