Comparison of Weight for Height and BMI for Age for Estimating Overnutrition Burden in Under-Five Populations With High Stunting Prevalence

Background: Overnourished under-five children are anthropometrically classified as either being at possible risk of overweight, overweight or obese and defined so, when either weight for height or body mass index for age (BMI-for-age) are >1SD to 2SD, >2SD to 3SD and >3SD, respectively of the analogous World Health Organization standards. Aim: To compare weight for height and BMI for age definitions for quantifying overnutrition burden. Methods: Theoretical consequences of ignoring age were evaluated by comparing, at varying height for age z-scores, the age- and sex-specific cutoffs of BMI that would define overnutrition with these two metrics. Overnutrition prevalence was then compared in simulated populations (short, intermediate and tall) and real-life datasets from India. Results: In short (-2SD) children, the BMI cutoffs with weight for height criteria were lower in comparison to BMI for age till 7-8 months, but higher at later ages. In National Family Health Survey-4, India dataset (short population), overnutrition (>1SD) prevalence with weight for height was higher from 0-0.5 years (exclusive breastfeeding age), but lower at subsequent ages. The prevalence difference (weight for height - BMI for age) in 0.5-5 years was -2.26% (6.57% vs 8.83%); this attenuated in 0-5 years (-1.55%; 7.23% vs 8.78%). The discrepancy was maximal for stunted children and was lower in girls. A similar pattern, of lower magnitude, was observed for overweight (>2SD) comparison. In intermediate and tall populations, there were no meaningful differences. Conclusion: The two definitions produce cutoffs, and hence estimates of overnutrition, that differ with the age, sex, and height of under-five children. The relative invariance, with age and height, of BMI for age, favors its use.

Relação entre maturação sexual e indicadores antropométricos e pressóricos em adolescentes / Relationship between sexual maturation and anthropometric and blood pressure indicators in teenagers

Resumo Objetivou-se investigar a relação entre a maturação sexual com indicadores antropométricos e pressóricos de adolescentes. Estudo transversal de base populacional, realizado entre 2018 e 2020, com 345 adolescentes de 10 a 19 anos. Coletou-se variáveis sociodemográficas e antropométricas, pressão arterial e maturação sexual. A análise dos dados foi feita por meio da Análise de Componentes Principais, que gerou três componentes e, posteriormente, testou-se a correlação entre a maturação sexual e os componentes gerados. A maioria dos adolescentes eram do sexo feminino (53%), normotensos (66,1%) e com peso normal (73%). Houve correlação positiva entre o desenvolvimento das mamas com o componente 1 e o componente 2, e correlação negativa entre mamas e o componente 3. Nos meninos, o desenvolvimento dos genitais e pelos pubianos estiveram positivamente correlacionados com o componente 2 e inversamente correlacionados com o componente 3. Conclui-se que existe relação entre a maturação sexual e os indicadores antropométricos e pressóricos, sendo variáveis representativas de risco cardiovascular em adolescentes, mesmo que não em sua totalidade.

Abstract This study aimed to investigate the relationship between sexual maturation and anthropometric and blood pressure indicators in teenagers. This was a population-based cross-sectional study, conducted with 345 teenagers, aged 10 to 19 years, between 2018 and 2020. In this study, data referent to sociodemographic and anthropometric variables, blood pressure, and sexual maturation were collected. The data analysis was performed by applying the Principle Component Analysis (PCA), which generated three components and then tested the correlation between sexual maturation and the generated components. Most of the teenagers were female (53%), normotensive (66.1%), and with a normal weight (73%). A positive correlation was found between breast development and component 1 and component 2, as well as a negative correlation between the breasts and component 3. In the boys, the development of genitals and pubic hair was positively correlated with component 2 and inversely correlated with component 3. It could therefore be concluded that there is a relationship between sexual maturation and the anthropometric and blood pressure indicators, which proved to be representative variables for cardiovascular risk in teenagers, even if not in their entirety.

Relación entre indicadores antropométricos y masa grasa medida por deuterio en escolares costarricenses / Relationship between anthropometric indicators and fat mass measured by deuterium in Costa Rican schoolchildren / Relação entre indicadores antropométricos e massa gordurosa medida por deutério em crianças da escola costarriquenhos

El propósito de este estudio fue identificar la relación entre la masa grasa expresada como porcentaje de grasa corporal (%GC) medida por el método de deuterio (D2O) e indicadores antropométricos en escolares costarricenses. Se trata de un estudio descriptivo transversal en el que participaron 54 niños y 49 niñas de 6 a 9 años. Se realizaron medidas antropométricas: peso, talla, índice de masa corporal, circunferencia de brazo, circunferencia de cintura, circunferencia abdominal, pliegue cutáneo subescapular y pliegue cutáneo tricipital. El análisis del %GC se realizó por medio del método de referencia del D2O. Se realizó una estadística descriptiva y se aplicó un análisis de coeficiente de correlación de Pearson para identificar la relación entre las mediciones antropométricas y el %GC obtenido por D2O. En el grupo de escolares, las niñas presentaron valores mayores de talla y pliegue cutáneo tricipital (p<0,05) y %GC obtenida por D2O (p<0,001). Se observó una fuerte correlación entre el %GC medido por D2O y el índice de masa corporal, la circunferencia de cintura y la circunferencia abdominal tanto en los niños como en las niñas. Se concluye que la circunferencia de cintura y la circunferencia abdominal podrían ser utilizadas conjuntamente con el IMC como herramientas para el diagnóstico de sobrepeso y obesidad en población escolar, cuando no se cuente con metodologías más precisas que determinen el %GC.

The purpose of this study was to identify the relationship between fat mass (FM) expressed as body fat percentage (%BF) measured by the deuterium method (D2O) and anthropometric indicators in Costa Rican schoolchildren. A cross-sectional descriptive study was performed and the participants were 54 boys and 49 girls of ages between six and nine years old. The anthropometric measurements recorded were weight, height, body mass index (BMI), arm circumference (AC), waist circumference (WC), abdominal circumference (AC), subscapular skinfold (SSF), and tricipital skinfold (TSF). The analysis of %BF was performed by means of D2O reference method. Descriptive statistics and the application of Pearson correlation coefficient analysis identified the relationship between anthropometric measurements and %BF obtained by D2O. From the group of schoolchildren, the girls showed greater values for height and tricipital skinfold (p<0.05) and %BF obtained by D2O (p<0.001). This study evidences a strong correlation between %BF measured by D2O and BMI, WC and AC in both girls and boys. It is concluded that WC and AC could be used together with the IMC as tools for the diagnosis of overweight and obesity in schoolchildren, when there are no more precise methodologies that determine the %BF.

O objetivo deste estudo foi identificar a relação entre a massa gordurosa (MG), expressa como percentagem de gordura corporal (%GC) medida pelo método de deutério (D2O) e indicadores antropométricos em escolas da Costa Rica. Trata-se de um estudo descritivo transversal, no qual participaram 54 meninos e 49 meninas com idade entre seis e nove anos. Foram realizadas medidas antropométricas: peso, tamanho, índice de massa corporal (IMC), circunferência do braço (CB), circunferência da cintura (CC), circunferência abdominal (CA), prega cutânea subescapular (PCS) e prega cutânea tricipital (PCT). A análise da %GC foi realizada pelo método de referência D2O, realizou-se uma estatística descritiva e foi aplicada análise coeficiente de correlação de Pearson para identificar a relação entre as medições antropométricas e a %GC obtida por meio do D2O. No grupo de escolares, as meninas apresentaram maiores valores de estatura e PCT (p<0,05) e %GC obtida por D2O (p<0,001). Observou-se uma importante correlação entre %GC medida por D2O e IMC, CC e CA tanto nos meninos quanto nas meninas. Conclui-se que a CC e a CA poderiam ser utilizadas conjuntamente com o IMC como ferramenta para o diagnóstico de sobrepeso e obesidade em população escolar, quando não se conte com metodologias mais precisas que determinem o %GC.

Caracterización del estado nutricional de pacientes posoperados con complicaciones en una unidad de cuidados intensivos / Characterization of the status of postoperative patients with complications in an intensive care unite

Introducción: Las unidades de atención al paciente gravemente enfermo informan numerosos casos con desnutrición. Para poder estimarlo es necesario utilizar indicadores dietéticos, antropométricos, bioquímicos e inmunológicos. Objetivo: Caracterizar el estado nutricional de los pacientes posoperados ingresados en una unidad de cuidados intensivos. Métodos: Se realizó un estudio descriptivo, prospectivo de corte transversal. Los valores se obtuvieron de los indicadores antropométricos (circunferencia media del brazo y circunferencia de la pantorrilla), bioquímicos (albúmina, colesterol, triglicéridos y creatinina) e inmunológicos (conteo total de linfocitos) de 98 pacientes ingresados en dicha unidad. El estado nutricional fue evaluado mediante variables independientes. Resultados: Predominaron los pacientes con estadía entre 1-7 días (71,4 por ciento), la ventilación mecánica se utilizó en 33,6 por ciento, fallecieron 19,3 por ciento de los pacientes, y predominó el grupo de afecciones intraabdominales 38,8 por ciento. La linfopenia (68,3 por ciento) y la hipoalbuminemia (62,2 por ciento) fueron más significativas, seguida de la circunferencia media del brazo (CMB) en rango de desnutrición (47,9 por ciento). No se demostró asociación de las variables nutricionales con la estadía, ni la necesidad de ventilación mecánica. Todas las variables se asociaron con el estado al egreso. Conclusiones: Predominó la estadía alrededor de una semana, la tercera parte de la muestra requirió apoyo ventilatorio, y la mortalidad fue baja. De las variables nutricionales estudiadas no se encontró asociación de estas con la estadía ni el uso de ventilación mecánica pero sí con el estado al egreso(AU)

Introduction: Critically ill care units report numerous cases of malnutrition. In order to estimate such statistics, it is necessary to use dietary, anthropometric, biochemical and immunological indicators. Objective: To characterize the nutritional status of postoperative patients admitted to an intensive care unit. Methods: A descriptive, prospective, cross-sectional study was carried out. The values ;were obtained from the indicators of the type anthropometric (average arm and calf circumference), biochemical (albumin, cholesterol, triglycerides and creatinine) and immunological (total lymphocyte count) of 98 patients admitted to the unit. The nutritional status was evaluated by independent variables. Results: Patients with 1-7 days of stay predominated (71.4 percent), mechanical ventilation was used in 33.6 percent, 19.3 percent of patients died, and the group of intra-abdominal conditions predominated (38.8 percent). Lymphopenia (68.3 percent) and hypoalbuminemia (62.2 percent) were more significant, followed by average arm circumference (AAC) in the malnutrition range (47.9 percent). There was no association of nutritional variables with the stay, nor the need for mechanical ventilation. All the variables were associated with the state at the time of discharge. Conclusions: A stay of about one week predominated, one third of the sample required ventilatory support, and mortality was low. Among all the nutritional variables studied, no association was found with the stay or the use of mechanical ventilation, but instead with the state at discharge(AU)

Objetivo: Avaliar índice de conicidade de pacientes adultos atendidos em um Ambulatório de Nutrição, associá-lo com presença de patologias e compará-lo a indicadores antropométricos quanto à sua eficácia como preditor de risco cardiometabólico. Metodologia: Estudo observacional com dados secundários de prontuários. Dados socioeconômicos, antropométricos (peso, índice de massa corporal, circunferência da cintura, do pescoço e índice de conicidade), número de consultas e hábitos de vida, foram obtidos e comparados entre a primeira e última consulta. As análises foram realizadas no pacote estatístico Stata® 11.1, com nível de significância de 5%. Resultados: Amostra constituída por 164 adultos, sendo 114 (70%) mulheres. A maioria apresentava hipertensão (45%), sedentarismo (48%), peso acima do ideal (90%) e valores de CC(82%), CP (82%) e IC (88%) acima do recomendado. A maioria apresentou perda de peso (77%), sendo que 29% perdeu mais de 5% do peso inicial, além de melhora significativa nos hábitos alimentares, principalmente pelas mulheres. O índice de conicidade associou-se significativamente com os indicadores antropométricos analisados; foi mais sensível nas mulheres quanto à classificação de risco de complicações metabólicas e cardiovasculares, e apresentou valores significativamente maiores nos hipertensos e diabéticos. Conclusão: É importante o acompanhamento nutricional para melhoria dos hábitos de vida dos pacientes, assim como a utilização do IC, que associou-se com hipertensão e diabetes,sendo mais sensível nas mulheres em relação ao risco de complicações cardiometabólicas do que a CC e CP, demonstrando ser um bom indicador antropométrico,capaz de possibilitar a detecção precoce da obesidade e da distribuição de gordura (AU)

Objective: Evaluate the conicity index of adult patients treated at a Nutrition Outpatient Clinic, to associate it with the presence of pathologies and to compare with anthropometric indicators as to its efficacy as a predictor of cardiometabolic risk. Methodology: Observational study with secondary data from medical records. Socioeconomic, anthropometric data (weight, body mass index, waist circumference, neck and conicity index), number of visits and life habits were obtained and compared between the first and last visit. The analyzes were performed in Stata® 11.1 statistical package, with a significance level of 5%. Results: Sample of 164 adults, 114 (70%) of whom were women. The majority had hypertension (45%), sedentarism (48%), weight above the ideal (90%) and values of CC (82%), CP (82%) and IC (88%) above recommended. The majority presented weight loss (77%), with 29% losing more than 5% of the initial weight, in addition to a significant improvement in eating habits, mainly by women. The taper index was significantly associated with the anthropometric indicators analyzed; was more sensitive in women regarding the risk classification of metabolic and cardiovascular complications, presented significantly higher values in hypertensive and diabetic patients. Conclusion: It is important nutritional monitoring to improve life habits of patients, as well as the use of HF, which was associated with hypertension and diabetes, being more sensitive in women in relation to the risk of cardiometabolic complications than CC and CP, proving to be a good anthropometric indicator, capable of making possible the early detection of obesity and fat distribution (AU)

Predictive capacity of anthropometric indicators for abdominal fat in the oldest old / Capacidade preditiva de indicadores antropométricos na indicação da gordura abdominal em idosos longevos

Cardiovascular diseases are a growing public health problem that affects most people over the age of 65 years and abdominal obesity is one of the risk factors for the development of these diseases. There are several methods that can be used to measure body fat, but their accuracy needs to be evaluated, especially in specific populations such as the elderly. The aim of this study was to assess the accuracy of anthropometric indicators to estimate the percentage of abdominal fat in subjects aged 80 years or older. A total of 125 subjects ranging in age from 80 to 95 years (83.5 ± 3), including 79 women (82.4 ± 3 years) and 46 men (83.6 ± 3 years), were studied. The following anthropometric indicators were used: body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), and waist-to-height ratio (WHtR). The percentage of abdominal fat was measured by DEXA. Sensitivity and specificity were analyzed using an ROC curve. The sensitivity, specificity and AUC were 0. 578, 0. 934 and 0. 756 for BMI, respectively; 0.703, 0.820 and 0.761 for WC; 0.938, 0.213 and 0.575 for WHR, and 0.984, 0.344 and 0.664 for WHtR. BMI and WC were the anthropometric indicators with the largest area under the curve and were therefore more adequate to identify the presence or absence of abdominal obesity.

As doenças cardiovasculares são um problema crescente de saúde pública que afeta grande parte das pessoas acima de 65 anos, sendo a obesidade abdominal um dos vários fatores para o desenvolvimento dessas doenças. Existem vários métodos para mensurar gordura corporal, mas é necessário analisar a capacidade preditiva desses métodos, principalmente em algumas populações específicas como, por exemplo, os idosos. O objetivo do presente estudo foi analisar a capacidade preditiva de indicadores antropométricos na estimativa do percentual de gordura abdominal de idosos com 80 anos ou mais. Foram avaliados 125 idosos com idade entre 80 e 95 (83,5+ 3 anos), sendo 79 mulheres (82,4 ± 3 anos) e 46 homens (83,6 ± 3 anos). Utilizaram-se os indicadores antropométricos: Índice de Massa Corporal(IMC), Circunferência de Cintura(CC), Razão Cintura Quadril(RCQ) e Razão Cintura Estatura(RCEst), e o percentual de gordura de tronco foi mensurado por meio do DEXA. Foi realizada a análise de sensibilidade(SENS) e especificidade(ESP) mediante a curva ROC, e o IMC apresentou valores de SENS=0,578; ESP=0,934 e AUC= 0,756, a CC SENS= 0,703; ESP= 0,820 e AUC=0,761, a RCQ SENS=0,938; ESP=0,213 e AUC=0,575 e a RCEst SENS=0,984; ESP=0,344 e AUC=0,664. O IMC e a CC foram os indicadores antropométricos que apresentaram maior área sob a curva, e sucessivamente com maior capacidade em detectar aqueles que têm ou não obesidade abdominal.

Lactancia materna y estado nutricional de niños entre 1 y 3 años de edad / Breastfeeding and nutritional status of children between 1 and 3 years of age

Se estudia la relación entre la lactancia materna y el estado nutricional de 127 niñas y 143 niños (n =270) de 1 a 3 años de edad, mediante un estudio de campo descriptivo y transversal, en ambulatorios de Caracas. Las variables estudiadas fueron: edad, sexo, estrato socioeconómico, tiempo y duración de la lactancia materna, peso, talla y las circunferencias del brazo y cabeza, para obtener la combinación de indicadores peso para la edad, peso para la talla y talla para la edad, y con ambas circunferencias el Índice de Kanawati-McLaren (K-McL= Circunferencia de brazo/Circunferencia de cabeza). Se aplicaron cuestionarios semiestructurados, al binomio madre-niño Predominaron los estratos sociales IV y V (Pobreza relativa y Crítica, respectivamente) según Graffar modificado, solamente el 17 % de la muestra pertenecía al estrato III (condiciones económicas medias). Al establecer la relación entre la lactancia y el estado nutricional según los indicadores hubo un comportamiento sin diferencias estadísticamente significativas. En cuanto a la combinación de indicadores y el tiempo y tipo de lactancia practicada en los niños ubicados entre percentiles 10 y 90 y con seis meses de lactancia exclusiva fue realizada sólo por el 8,33% de ellos. En los desnutridos con talla normal, la cifra fue igualmente cercana: 10,81% para esa práctica. Los varones estaban desnutridos en un 21% y las niñas en un 13%. Al aplicar K-McL: 75,63% de los niños amamantados hasta el día de la entrevista resultaron normales (percentil 50 o mediana) y los no amamantados hasta ese momento sumaron un 70,83%(AU)

This study examines the relationship between breastfeeding and nutritional status of 127 girls and 143 boys (n =270) 1 to 3 years of age. It was carried out a field descriptive and cross-sectional study in clinics of Caracas. The anthropometric variables were: age, sex, socioeconomic strata, time and duration of the maternal breastfeeding, weight, height, and cephalic and arm circumferences, for the combination of indicators: weight for age, weight for height and height for age, and with both the index Kanawati-McLaren (K-McL) circles and semi structure questionnaires have been implemented. The social stratum IV and V predominated (relative poverty and criticism, respectively) according to modified Graffar, only 17% of the sample belongs to the stratum III (average economic conditions). To establish the relationship between breastfeeding and nutritional status according to the indicators, there was a behavior without statistically significant differences. The combination of indicators and the time and breastfeeding practiced in located children (between 10 and 90 percentile) and six months of exclusive breastfeeding was performed only by 8.33 % of them. In the malnourished with normal stature, the figure was also close: 10,81% for this practice. The boys were undernourished by 21% and the girls by 13%. Applying K-McL: 75, 63% of the children breastfed until the day of the interview were normal (percentile 50 or median), and not breastfed until that time amounted to 70, 83 %(AU)

Indicadores antropométricos de desnutrição em pacientes politraumatizados / Anthropometric indicators of malnutrition in patients with multiple trauma

Objetivo. Avaliar a concordância entre alguns indicadores antropométricos no diagnóstico de desnutrição em pacientes politraumatizados internados em um hospital público de Goiânia.Método. Estudo transversal realizado com indivíduos adultos e idosos de ambos os sexos, cujos dados foram coletados por meio de questionário padronizado e de aferição das medidas antropométricas. Os pontos de corte para o índice de massa corporal foram os recomendados pela Organização Mundial da Saúde (1998) para pacientes adultose, para pacientes idosos, os sugeridos por Lipschitz (1994). Para a classificação do estado nutricional de acordo com o perímetro braquial e o perímetro muscular do braço, usaram-se os pontos de corte sugeridos por Blackburn e Thornton (1979) e, para o perímetro da panturrilha, os pontos de corte recomendados por Vellas (1999). As análises estatísticasforam realizadas no programa STATA/SE. Resultados. Participaram do estudo 33 pacientes, sendo 80,6% eutróficos conforme o índice de massa corporal. Dos nove enfermos apontados pelo perímetro braquial como desnutridos, apenas dois tiveram esse mesmo resultadopelo referido índice de massa corporal. Dos onze pacientes classificados com desnutrição pelo perímetro muscular do braço, apenas dois deles foram classificados como desnutridos pelo índice de massa corporal. Dos oito pacientes que foram classificados com desnutrição pelo perímetro da panturrilha, apenas três foram classificados como desnutridospelo índice de massa corporal. Conclusão. Observou-se discordância entre os métodos avaliados. Faz-se necessário o emprego associado dosvários indicadores antropométricos para melhorar a acurácia do diagnóstico nutricional.

Objective. To evaluate the agreement between some anthropometric indicators of malnutrition in the diagnosis of multiple trauma patients admitted in public hospital in Goiania. Method. Cross-sectional study with adults and older people of both sexes, whose data were collected froma standardized questionnaire and anthropometric measures. The cutoff points for body mass index were those recommended by the World Health Organization (1998) for adults patients and for elderly patients the cutoff points suggested by Lipschitz (1994). For the classification of nutritional status according to arm perimeter and arm muscle perimeter, we used the cutoff points suggested by Blackburn and Thornton (1979) and, to the calf perimeter the cutting points recommended by Vellas (1999). Analyses were performed in STATA/SE program. Results. The study included 33 patients, being 80.6% with normal weight as indicated by the body mass index. Of the nine patients indicated by arm perimeter as malnourished, only two showed the same result by the body mass index. Of the eleven patients who were classified as malnourished by the arm muscle perimeter, only two were classified as malnourished by the mentioned body mass index. Since the eight patients who were classified as malnourished by the calf perimeter, only three were classified as malnourished by the body mass index. Conclusion. There was disagreement among the evaluated methods. It is necessary to use the various associated anthropometric indicators to improve the accuracy of nutritional diagnosis.

Antropometria na avaliação da obesidade abdominal e risco coronariano / Anthropometry for the assessment of abdominal obesity and coronary risk

A incidência de diabetes, aterosclerose e morte cardíaca súbita é bastante frequente em pessoas obesas, porém quando a obesidade está centralizada na região abdominal as repercussões negativas, tanto de ordem metabólica quanto cardiovascular são mais significativas.O objetivo do estudo foi analisar e comparar entre os indicadores antropométricos de obesidade abdominal mais utilizados, quais deles apresentam maior poder preditivo para discriminar risco coronariano elevado (RCE) e propor pontos de corte para sua utilizaçãona prática clínica e populacional em adultos brasileiros. Foram analisados os manuscritos publicados pelo grupo de pesquisa em doenças crônicas não transmissíveis do Instituto de Saúde Coletiva (ISC) da Universidade Federal da Bahia (UFBA) que compararam diversos indicadores antropométricos como preditores de RCE. As evidências com base nos estudos analisados permitem sugerir para avaliação da obesidade abdominal: na prática clínica, utilizar o índice de conicidade (Índice C) com os pontos de corte de 1,25 para homens, 1,18 e 1,22 para mulheres até 49 anos e a partir de 50 anos de idade, respectivamente; em estudos populacionais, utilizar a razão cintura-estatura (RCest) com a mensagem de que a cintura não deve ser maior que a metade da estatura de determinada pessoa.

The incidence of diabetes, atherosclerosis and sudden cardiac death is high among obese individuals, with significant metabolic and cardiovascular adverse effects being observed when obesity is centered in the abdominal region. The objective of this study was to determinewhich of the anthropometric indicators of abdominal obesity commonly used show the highest predictive power to discriminate a high coronary risk (HCR) and to propose cut-off values for their use in clinical practice and in population studies on Brazilian adults. The studies publishedby the research group on non-transmissible chronic diseases of the Public Health Institute (PHI), Federal University of Bahia (UFBA), that compare different anthropometric indicators as predictors of HCR were analyzed. The evidence provided by the studies analyzed suggests the use of the conicity index for the evaluation of abdominal obesity in clinical practice, with cut-off values of 1.25 for men and of 1.18 and 1.22 for women ? 49 years and > 50 years, respectively. The waist-height ratio should be used in population studies, with the recommendation that waist should not exceed half the height of a particular subject.

Anthropometric and Biochemical Indicators and Related Factors for the Community Dwelling Elderly Living Alone / 대한지역사회영양학회지

In this study, anthropometric and biochemical indicators and related factors for community dwelling elderly living alone (ELA). as well as for elderly not living alone (ENLA) were explored. The subjects were 140 elderly females (70 living alone, 70 not living alone) residing in Bucheon. Anthropometric measurements revealed significant differences between the two groups (ELA/ENLA) for height, weight, BMI, triceps skinfold thickness, suprailiac skinfold thickness, subscapular skinfold thickness, and body fat percentage. The ELA showed significantly lower data for most of the anthropometric indices, except PIBW. Biochemical indicators of iron status (hemoglobin, serum iron, transferrin saturation) were significantly lower for the ELA, whereas the total serum cholesterol, LDL-C, LDL-C/HDL-C, for the ELA were significantly higher. The prevalence of hypercholesterolemia (240 mg%) was 30%. The latter three are not in accordance with general malnutrition among the ELA. The hemoglobin of the ELA was positively correlated with energy, fat, iron and cholesterol intake, but negatively correlated with height. The serum cholesterol of the ELA was positively associated with most of their nutrient intake.
