RESUMO

OBJECTIVE: The aim was to identify trajectory patterns of weight and length in children from birth until two years of life and establish associations with maternal and child characteristics. METHODS: A mixed-cohort study was conducted in public health services in Colombo-PR, Brazil, between 2018 and 2022. Pregnancy information was gathered through anthropometric data collection and questionnaires. Birth data were extracted from birth record forms, while weight and length data in the first two years of life were obtained from physical and electronic health service records. Weight and length trajectory patterns were identified using a group-based trajectory model. The definition of the number of trajectory patterns to be selected considered the model fit to the type of variable, its practical utility, as well as the probabilities of group membership. RESULTS: Two trajectory patterns of weight and length were identified among the children. The majority exhibited a pattern of weight (67.8%, n = 382) and length (90.9%, n = 472) considered high and stable, with a tendency to decelerate from one and a half years of age. The probability of belonging to the lower weight gain group was associated with female sex (41.5%, p < 0.001), smoking during pregnancy (48.7%, p = 0.008), prematurity (65.0%, p = 0.001), cesarean delivery (36.4%, p = 0.009), small for gestational age (69.0%, p < 0.001), and twinning (69.2%, p = 0.002). Similarly, the probability of belonging to the lower length gain group was associated with female sex (11.7%, p < 0.001), smoking during pregnancy (20.6%, p = 0.003), cesarean delivery (10.1%, p = 0.048), born small for gestational age (46.4%, p < 0.001), and twinning (46.1%, p < 0.001). CONCLUSION: Conditions during pregnancy and childbirth can impact growth patterns in the first two years of life.

RESUMO

OBJECTIVES: In the clinical routine of pediatricians, height is the most reliable indicator for assessing growth. However, there are situations where it is not possible to measure this parameter directly, making the estimation of height or length a useful alternative. The main goal of this study is to identify which segmental measure, including upper arm length (UAL), tibial length (TL), and knee-heel length (KHL), provides the stature estimate that most closely approximates directly measured height in the study participants. METHODS: Analytical cross-sectional study of the anthropometric and segmental measures of 248 participants, aged 0 to 14 years old, using Stevenson's and Kihara's equations to estimate indirectly measured height. RESULTS: The segmental measure that provided a measurement that deviated the least from the actual height was the KHL, followed by TL, both calculated using Stevenson's equations. CONCLUSION: The use of segmental measures to infer a child's stature is valuable in clinical practice, particularly in bedridden and incapacitated patients. Based on the present findings, the KHL and TL segments yielded more accurate results than the UAL.

Abstract Objective: To develop growth charts for weight-for-age, height-for-age, and body mass index (BMI)-for-age for both genders aged 2 to 18 years for Brazilian patients with Williams-Beuren Syndrome (WBS). Methods: This is a multicenter, retrospective, and longitudinal study, data were collected from the medical records of boys and girls with a confirmed diagnosis of WBS in three large university centers in the state of Sao Paulo, Brazil. Growth charts stratified by gender and age in years were developed using LMSchartmaker Pro software. The LMS (Lambda Mu Sigma) method was used to model the charts. The quality of the settings was checked by worm plots. Results: The first Brazilian growth charts for weight-for-age, height-for-age, and BMI-for-age stratified by gender were constructed for WBS patients aged 2 to 18 years. Conclusion: The growth charts developed in this study can help to guide family members and to improve the health care offered by health professionals.

RESUMO

BACKGROUND & AIMS: In children with Cerebral palsy (CP) bone deformities create a difficulty in the collection of height measures by direct methods. Body segments are an alternative to study for anthropometric evaluation in children with CP. Motor compromise affects growth in these children. To our knowledge, no equations have been developed to estimate height that consider the level of involvement of children with CP. The aim was to develop equations to estimate height using segmental measures for children with cerebral palsy (CP). METHODS: This was a cross-sectional study. The sample consisted of children and adolescents with CP of both sexes from 2 to 19 years old from five cities in Argentina. Children whose height and knee-heel height (KH) could be measured were included. Height, KH, and clinical covariables were collected. Linear regression models with height as the dependent variable and KH as predictors adjusted for significant covariates were developed and compared for R2, adjusted R2, and the root mean square of the error. RESULTS: 242 children and adolescents (mean age 9 ± 4 years) with a confirmed diagnosis of CP were included. The interaction between height and other variables such KH, sex, GMFCS, and age was analyzed. Two equations were developed to estimate height according to GMFCS level (GMFCS Level I-III: H = 1.5 × KH(cm) + 2.28 × age(years) + 51; GMFCS Level IV-V: H = 2.13 × KH (cm)+ 0.91 × age(years) + 37). The concordance correlation coefficient between estimated and observed height was 0.95 (95%CI [0.94; 0.96]). CONCLUSION: Height in children and adolescents with CP can be predicted using KH, GMFCS, and age. The equations and software can estimate height when this cannot be obtained directly.

RESUMO

ABSTRACT Objective Evaluate short stature as a possible explanation for obesity, and identify if consumption of energy, protein, carbohydrate, and lipids were associated to higher risk for obesity in Brazilian adults (20-59 y) living in household food insecurity. Methods Cross-sectional study from 2017/2018 Household Budget Survey (N=28,112). Food insecurity was measured with the Brazilian Household Food Insecurity Measurement Scale. Short stature was used as an indicator of malnutrition at the beginning of life, which characterizes metabolic alterations resulting from the presence of food insecurity (cuts off women ≤149cm; men ≤160cm). Body mass index (kg/m2) was estimated from self-reported weight and body height. The average food intake was estimated from a 24-hr recall. The weighted means and standard error of the food security/insecurity categories were assessed according to height, mean energy intake and protein(g), carbohydrate(g) and lipids(g) intake, stratified by gender and nutritional status. Results Both men and women with obesity and food insecurity had significantly lower average height in comparison with those in food security status (p-value <0.01). The prevalence of obesity 1 (BMI 30-34.9kg/m2) increased significantly with the food insecurity among women. There was a trend towards short stature among obese women from families with food insecurity, as well as lower intake of energy. Among both men and women, the lowest intakes of protein and the highest intake of carbohydrates were observed in the underweight group (BMI <18.5kg/m2). Conclusion In women, the risk of obesity may depend on the metabolic background, since who presents food insecurity and develop obesity have low stature and lower energy intake.

RESUMO Objetivo Avaliar a baixa estatura como possível explicação para a obesidade, e identificar se o consumo de energia, proteína, carboidrato e lipídios esteve associado ao maior risco de obesidade em adultos brasileiros (20-59 anos) que vivem em domicílios em insegurança alimentar domiciliar. Métodos Estudo transversal realizado com dados da Pesquisa de Orçamentos Familiares 2017/2018 (N=28.112). A Insegurança alimentar domiciliar foi medida pela Escala Brasileira de Insegurança Alimentar. A baixa estatura (mulheres ≤149cm; homens ≤160cm) foi utilizada como indicador de alterações metabólicas decorrentes da presença de insegurança alimentar. O índice de massa corporal (kg/m2) foi estimado a partir do peso e altura autorreferidos. A média de ingestão alimentar foi estimada a partir do recordatório de 24 horas. As médias ponderadas e o erro padrão das categorias de segurança/insegurança alimentar foram avaliadas segundo estatura, médias de ingestão energéticas e de proteínas(g), carboidratos(g) e lipídios(g), estratificado por sexo e estado nutricional. Resultados Homens e mulheres com obesidade e insegurança alimentar apresentaram a média de estatura significativamente menor em comparação aqueles com segurança alimentar (p-valor <0,01). A prevalência de obesidade 1 (índice de massa corporal 30-34,9Kg/m2) aumentou significativamente com a insegurança alimentar entre as mulheres. Houve tendência de baixa estatura entre mulheres obesas de famílias com insegurança alimentar, bem como menor ingestão de energia. Entre homens e mulheres, a menor ingestão de proteína e a maior ingestão de carboidratos foram observadas no grupo de baixo peso (índice de massa corporal <18,5Kg/m2). Conclusão Nas mulheres, o risco de obesidade pode depender do metabolismo, pois quem apresenta insegurança alimentar e desenvolve obesidade possui baixa estatura e menor ingestão energética.

RESUMO

SUMMARY: The liver has over 500 physiological and biochemical roles in our organism so checking of liver size and function is a part of every clinical examination. Aim of our research was to estimate liver size on computed tomography (CT) of the abdomen images and to determinate relations between liver dimensions and anthropometric parameters. The research included 99 patients, 49 men and 50 women, who were referred for CT of abdomen. We measured body height (BH) and body mass (BM), and calculated body mass index (BMI) and body surface area (BSA). Also, on CT images we measured anteroposterior (AP), laterolateral (LL) and two craniocaudal liver diameters (one at the level of midclavicular line - CCmcl, and the other was maximal - CCmax). Liver volume (LV) was calculated with formula. Our results showed that AP diameter positively correlated with BSA (r=0.30) in women. LL diameter positively correlated with BH (r=0.43), and BSA (0.31) in men. CCmcl diameter positively correlated with BH (r=0.33), BM (r=0.31), and BSA (r=0.34) in men, while in women it correlated only with BH (r=0.38). CCmax diameter positively correlated with BH (r=0.33) and BSA (r=0.33) in men. LV positively correlated with BH and BSA in both men (r=0.36, r=0.33, respectively) and women (r=0.42, r=0.31, respectively), and in men also with BM (r=0.34). LL, CCmcl, CCmax, and LV negatively correlated with aging in both sexes After the age of 60, there was a decrease in size of LL, CC diameters, as well as in LV. We concluded that liver dimensions decrease with aging, regardless of sex at the expanse of LL and CC diameters which are related to the size of body parameters, so that for a precise evaluation of liver size all three diameters should be measured, LV as well as BH, BM, and BSA.

El hígado desempeña más de 500 funciones fisiológicas y bioquímicas en nuestro organismo, por lo que comprobar el tamaño y la función de este órgano es parte de cada examen clínico. El objetivo de nuestra investigación fue estimar el tamaño del hígado mediante tomografía computarizada (TC) de imágenes del abdomen y determinar las relaciones entre las dimensiones del hígado y los parámetros antropométricos. La investigación incluyó a 99 pacientes, 49 hombres y 50 mujeres, que fueron remitidos para TC de abdomen. Medimos la altura corporal (BH) y la masa corporal (BM), y calculamos el índice de masa corporal (IMC) y el área de superficie corporal (BSA). Además, en las imágenes de TC medimos los diámetros hepáticos anteroposterior (AP), laterolateral (LL) y dos craneocaudales (uno a nivel de la línea medioclavicular - CCmcl, y el diámetro máximo - CCmax). El volumen del hígado (VI) se calculó con una fórmula. Nuestros resultados mostraron que el diámetro AP se correlacionó positivamente con BSA (r = 0,30) en mujeres. El diámetro de LL se correlacionó positivamente con BH (r=0,43) y BSA (0,31) en hombres. El diámetro CCmcl se correlacionó positivamente con BH (r=0,33), BM (r=0,31) y BSA (r=0,34) en hombres, mientras que en mujeres se correlacionó solo con BH (r=0,38). El diámetro CCmax se correlacionó positivamente con BH (r=0,33) y BSA (r=0,33) en hombres. El VI se correlacionó positivamente con BH y BSA tanto en hombres (r=0,36, r=0,33, respectivamente) como en mujeres (r=0,42, r=0,31, respectivamente), y en hombres también con BM (r=0,34). LL, CCmcl, CCmax y LV se correlacionaron negativamente con el envejecimiento en ambos sexos. Después de los 60 años, hubo una disminución en el tamaño de los diámetros LL, CC y LV. Concluimos que las dimensiones del hígado disminuyen con la edad, independientemente del sexo, en la extensión de los diámetros LL y CC que están relacionados con el tamaño de los parámetros corporales, por lo que para una evaluación precisa del tamaño del hígado se debe medir LV como BH, BM y BSA.

RESUMO

This study compared the distribution of stunting and height-for-age (HAZ) Z-scores among age groups in data from the Brazilian National Survey on Demography and Health of Women and Children (PNDS 2006) and the Brazilian National Survey on Child Nutrition (ENANI-2019). The final sample comprised 4,408 and 14,553 children < 59 months of age in the PNDS 2006 and ENANI-2019, respectively. Children with HAZ scores < -2 according to the World Health Organization (WHO) growth standard were classified as stunted. Prevalence, 95% confidence intervals (95%CI), means, and standard deviations were estimated for Brazil and according to age. The distribution of HAZ scores at each age (in months) was estimated using the svysmooth function of the R survey package. Analyses considered the complex sampling design of the studies. Statistical differences were determined by analyzing the 95%CI of the overlap of point estimates. From 2006 to 2019, the prevalence of stunting for children < 12 months of age increased from 4.7% to 9%. As expected, the smoothed curves showed a higher mean HAZ score for children < 24 months of age in 2006 than in 2019 with no overlap of 95%CI among children aged 6-12 months. For children ≥ 24 months of age, we observed a higher mean HAZ score in 2019. Although the prevalence of stunting among children < 59 months of age was similar between 2006 and 2019, mean HAZ scores among children ≥ 24 months of age increased, whereas the mean HAZ score among children < 24 months of age decreased. Considering the deterioration in living conditions and the potential impact of the COVID-19 pandemic, we expect a greater prevalence of stunting in Brazil in the near future.

Este estudo comparou a distribuição dos escores Z de estatura (ZAI) e déficit de estatura por faixas etárias nos dados da Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher (PNDS 2006) e da Pesquisa Nacional de Nutrição Infantil (ENANI-2019). Nossa amostra final foi composta por 4.408 e 14.553 crianças < 59 meses de idade da PNDS 2006 e ENANI-2019, respectivamente. Crianças com escores HAZ < -2 de acordo com o padrão de crescimento da Organização Mundial da Saúde (OMS) foram classificadas como tendo déficit de estatura. Prevalências, intervalos de 95% de confiança (IC95%), médias e desvios padrão foram estimados para o Brasil e de acordo com a idade. A distribuição dos HAZ em cada idade (em meses) foi estimada usando a função svysmooth do pacote R. Nossas análises consideraram o desenho amostral complexo dos estudos. Diferenças estatísticas foram determinadas pela análise da sobreposição pontual dos IC95%. Entre 2006 e 2019, a prevalência de déficit de estatura para crianças < 12 meses de idade aumentou de 4,7% para 9%. Como esperado, as curvas suavizadas revelaram um HAZ médio maior para crianças < 24 meses de idade em 2006 do que em 2019, sem sobreposição de IC95% entre crianças de 6-12 meses. Para crianças ≥ 24 meses de idade, observamos um HAZ médio maior em 2019. Embora a prevalência de déficit de estatura entre crianças < 59 meses de idade tenha sido semelhante entre 2006 e 2019, observamos um aumento no HAZ médio entre crianças ≥ 24 meses de idade e uma diminuição no HAZ médio entre crianças < 24 meses de idade. Considerando a deterioração das condições de vida e o potencial impacto da pandemia de COVID-19, espera-se uma maior prevalência de déficit de estatura no Brasil no futuro próximo.

Este estudio comparó la distribución de las puntuaciones Z de talla (ZTE) y el déficit de estatura por grupos de edad en los datos de la Encuesta Nacional de Demografía y Salud del Niño y de la Mujer (PNDS 2006) y la Encuesta Nacional de Nutrición Infantil (ENANI-2019). Nuestra muestra final consistió en 4.408 y 14.553 niños < 59 meses de edad de PNDS 2006 y ENANI-2019, respectivamente. Los niños con puntuaciones HAZ < -2 según el patrón de crecimiento de la Organización Mundial de la Salud (OMS) se clasificaron como con déficit de talla para edad. Las prevalencias, los intervalos de 95% de confianza (IC95 %), las medias y las desviaciones estándar se estimaron para Brasil y según la edad. La distribución de HAZ para cada edad (en meses) se estimó utilizando la función svysmooth del paquete R. Nuestros análisis tuvieron en cuenta el complejo diseño de muestra de los estudios. Las diferencias estadísticas se determinaron mediante el análisis de la superposición puntual de los IC95 %. Entre 2006 y 2019, la prevalencia del déficit de talla para edad en niños < 12 meses de edad aumentó del 4,7 % al 9%. Como se esperaba, las curvas suavizadas revelaron un HAZ promedio mayor para los niños < 24 meses de edad en 2006 que en 2019, sin una superposición del IC95 % entre los niños de 6-12 meses. Para los niños ≥ 24 meses de edad, observamos un HAZ promedio mayor en 2019. Aunque la prevalencia del déficit de talla para edad entre los niños < 59 meses de edad fue similar entre 2006 y 2019, observamos un aumento en el HAZ promedio entre los niños ≥ 24 meses de edad y una disminución en el HAZ promedio entre los niños < 24 meses de edad. Teniendo en cuenta el deterioro de las condiciones de vida y el impacto potencial de la pandemia de COVID-19, se espera una mayor prevalencia de déficit de talla para edad en Brasil en un futuro cercano.

RESUMO

BACKGROUND: Neurofibromatosis 1 (NF1) is a common autosomal dominant syndrome with complete penetrance and highly variable expressivity. The cutaneous neurofibroma (Cnf) and plexiform neurofibroma (Pnf), café-au-lait spots, and freckle-like lesions are common in NF1, but many other manifestations can occur. We aimed to evaluate head circumference, height, weight, body mass index (BMI), head circumference-to-height ratio (HCHR) and waist-hip ratio (WHR) in adult NF1 Brazilian individuals versus a paired control group and investigate their correlation with the presence of clinically visible Pnfs, and number of "skin neurofibromas" (Snf), which include both cutaneous and subcutaneous neurofibromas. METHODS: A case-control study was conducted with 168 individuals, 84 with NF1 and 84 without NF1, paired by sex and age. Head circumference and anthropometric measurements, Snf quantification, evaluation of clinically visible Pnf and familial inheritance were accessed. RESULTS: Prevalence of macrocephaly was significantly higher in NF1 women. Height and weight were significantly lower in both males and females with NF1. HCHR was higher in the NF1 group than in the control group for both sexes. BMI was significantly lower in men with NF1. Waist and hip circumferences were significantly reduced in NF compared with the controls, but the mean WHR was significantly lower only in NF1 women. No correlation was found between the Snf and head circumference and anthropometric measurements, sex or family history. The presence and larger size of clinically visible plexiform neurofibromas were associated with normal stature (p = 0.037 and p = 0.003, respectively). CONCLUSIONS: NF1 individuals have increased prevalence of macrocephaly, short stature, low BMI, and reduced abdominal fat. There is no relation between head circumference and anthropometric data with family history, or neurofibromas.

RESUMO

PURPOSE: Patients with hereditary hypophosphatemic rickets are short and disproportionate and very little information is available on segmental growth, but the body disproportion at adulthood leads us to think that the growth velocity of legs is slower. METHODS: A total of 96 children were included and molecular testing was carried out in 42. Children who reached adult height were classified into two groups according to their compliance to conventional treatment (phosphate supplement and calcitriol). Individual growth records of height and sitting height/height were plotted using Argentine reference data in 96 children and growth curves were estimated by fitting Preece-Baines Model 1 in 19 of the children. RESULTS: Molecular testing revealed sequence deleterious alterations or large deletions in 36/42 patients. During childhood, 76% of children grew below - 1.88 standard deviation score (SDS) and 97% had body disproportion. During adolescence, the mean peak height velocity for the good and poor compliance to treatment groups was 7.8 (0.6) and 5.4 (0.4) cm/year in boys and 7.0 (0.7) and 5.2 (0.8) cm/year in girls, respectively. At adulthood, the median sitting height/height ratio was 2.32 and 6.21 SDS for the good and poor compliance to treatment groups, respectively. The mean pubertal growth spurt of the trunk was -0.8 (1.4) SDS, with a short pubertal growth spurt of - 1.8 (0.4) SDS for limbs in the good compliance group. Median adult height in 13/29 males and 30/67 females was -4.56 and -3.16 SDS, respectively. CONCLUSION: For all patients the growth spurt was slower, secondary to a short growth spurt of limbs, reaching a short adult height with body disproportion that was more prominent in the poor compliance group.

RESUMO

OBJECTIVE: To evaluate the outcome of food intake and nutritional status post discontinuation of a cow's-milk-free diet after a negative oral food challenge. METHODS: This was a prospective, uncontrolled study that evaluated food intake and nutritional status of a cohort of 80 infants and children under 5 years of age. Food intake and nutritional status were evaluated on the day of the oral food challenge test and after 30 days. Weight and height were measured on the day of the test and after 30 days. RESULTS: The mean age of the patients was 18.7 ± 12.4 months, and 58.7% were male. After discontinuation of the elimination diet, the children showed daily intake increases in (P < 0.001), protein (P < 0.001), carbohydrates (P = 0.042), calcium from foods (P < 0.001), calcium from foods and supplements (P < 0.001), phosphorus (P < 0.001), and vitamin D from foods (P = 0.006). The Z-scores (n = 76) on the day of the oral food challenge test and 30 days after restarting the consumption of cow's milk were as follows: weight-for-age (P < 0.001) and height-for-age (P < 0.001), respectively. CONCLUSION: Cow's milk protein in the diet was associated with increased intake of energy, proteins, carbohydrates, calcium, phosphorus, and vitamin D, in addition to an increase in the Z-scores for weight-for-age and height-for-age.

RESUMO

This study aims to describe the mean height of adolescents from the five regions of Brazil and to evaluate socioeconomic and nutritional factors associated with normal growth. This is a cross-sectional study conducted in the Brazilian urban and rural areas with students aged 12 to 17 years (n = 71,553). Anthropometry, socioeconomic variables, physical activity, and diet were evaluated. Height-for-age z-scores were calculated and multiple linear regression models were used to investigate the association of exposure variables with height (outcome) by sex and age (12-13, 14-15, and 16-17 years). We observed a lower mean height in adolescents from the North Region and in individuals with low socioeconomic status. At 17 years of age, the closest to the final height in this sample, mean heights for girls and boys were 160.9 ± 0.1cm and 173.7 ± 0.3cm, respectively. In multiple linear regression analysis, physical activity (girls β = 0.119, 95%CI: 0.035; 0.202; boys β = 0.092, 95%CI: 0.012; 0.172) and high level of maternal education (girls β = 0.103, 95%CI: 0.001; 0.204; boys β = 0.39, 95%CI: 0.245; 0.534) were positively associated with height-for-age z-score in 16- to 17-year-old boys and girls. Other factors positively associated with height-for-age z-score in older students include higher protein consumption (β = 0.022, 95%CI: 0.010; 0.035) and obesity (β = 0.217, 95%CI: 0.084; 0.350) for boys, and low weight (β = 0.205, 95%CI: 0.028, 0.382) for girls. We observed differences in the mean height among adolescents from the five Brazilian regions. Normal growth, especially among older adolescents, was associated with high maternal education, practice of physical activity, protein consumption, and body mass index (BMI) categories.

Buscou-se descrever a altura média dos adolescentes das cinco regiões do Brasil e avaliar os fatores socioeconômicos e nutricionais que estejam associados ao seu crescimento normal. Este é um estudo transversal realizado em ambientes urbanos e rurais no Brasil com estudantes de 12 a 17 anos (n = 71.553). Avaliamos antropometria, variáveis socioeconômicas, atividade física e dieta. Calculou-se os escores-z por idade e investigou-se a associação das variáveis de exposição com altura (desfecho) por sexo e idade (12-13, 14-15 e 16-17 anos) através de múltiplos modelos de regressão linear. Observou-se menor altura média em adolescentes da região Norte e em baixos níveis socioeconômicos. Aos 17 anos, o mais próximo da altura final nesta amostra, as alturas médias para meninas e meninos foram de 160,9 ± 0,1cm e 173,7 ± 0,3cm, respectivamente. Na análise de regressão linear múltipla, atividade física (meninas β = 0,119, IC95%: 0,035; 0,202; meninos β = 0,092, IC95%: 0,012; 0,172) e Ensino Médio materno (meninas β = 0,103, IC95%: 0,201; 0,204; meninos β = 0,39, IC95%: 0,245; 0,534) estiveram positivamente associados ao escore-z de altura por idade em meninos e meninas de 16-17 anos. Maior consumo de proteína (β = 0,022, IC95%: 0,010; 0,035) e obesidade (β = 0,217, IC95%: 0,084; 0,350) estiveram positivamente associados ao escore-z de altura para a idade meninos mais velhos, enquanto a variável associada às meninas foi baixo peso (β = 0,205, IC95%: 0,028; 0,382). Observou-se diferenças na altura média de adolescentes das cinco regiões brasileiras. O crescimento normal, especialmente entre adolescentes mais velhos, esteve associado à escolaridade materna, à prática de atividade física, ao consumo de proteínas e às categorias de índice de massa corporal (IMC).

Los objetivos fueron describir la estatura media de los adolescentes de las cinco regiones de Brasil y evaluar los factores socioeconómicos y nutricionales asociados al crecimiento normal. Estudio transversal realizado en entornos urbanos y rurales de Brasil con estudiantes de 12 a 17 años (n = 71.553). Se evaluaron la antropometría, las variables socioeconómicas, la actividad física y la dieta. Se calculó la puntuación Z de la altura para la edad y se utilizaron modelos de regresión lineal múltiple para investigar la asociación de las variables de exposición con la altura (resultado) por sexo y edad (12-13, 14-15 y 16-17 años). Se observó una estatura media más baja en los adolescentes de la región norte y en los de nivel socioeconómico bajo. A los 17 años, la edad más cercana a la estatura final en esta muestra, las estaturas medias de las chicas y los chicos eran de 160,9 ± 0,1cm y 173,7 ± 0,3cm, respectivamente. En el análisis de regresión lineal múltiple, la actividad física (chicas β = 0,119, IC95%: 0,035; 0,202; chicos β = 0,092, IC95%: 0,012; 0,172) y la madre con educación secundaria (chicas β = 0,103, IC95%: 0,001; 0,204; chicos β = 0,39, IC95%: 0,245; 0,534) se asociaron positivamente con la puntuación z de la altura para la edad en chicos y chicas de 16-17 años. En el caso de los chicos, el mayor consumo de proteínas (β = 0,022, IC95%: 0,010; 0,035) y la obesidad (β = 0,217, IC95%: 0,084; 0,350), mientras que, en el caso de las chicas, el bajo peso (β = 0,205, IC95%: 0,028; 0,382) también se asociaron positivamente con la puntuación z de la altura para la edad en los estudiantes mayores. Se observaron diferencias en la estatura media entre los adolescentes de las cinco regiones brasileñas. El crecimiento normal, especialmente entre los adolescentes de mayor edad, se asoció con la alta escolaridad de la madre, la práctica de actividad física, el consumo de proteínas y las categorías de índice de masa corporal (IMC).

Método Estudo transversal observacional realizado com 130 recém-nascidos em aleitamento materno exclusivo. A coleta de dados foi realizada por fonoaudiólogas devidamente treinadas e calibradas. As medidas orofaciais dos recém-nascidos foram realizadas com uma régua maleável e transparente de 10 cm de comprimento, nos seguintes segmentos: alturas do terço superior (tr-g), do terço médio (g-sn) e do terço inferior da face (sn-gn); altura do filtro (sn-Is); distância entre o canto do olho e a comissura labial do lado direito e esquerdo (ex-ch). A medida do peso e da altura foram coletadas nos prontuários dos recém-nascidos. Os dados foram submetidos à análise estatística, sendo aplicado o teste de Mann-Whitney, adotando nível de significância de 5%. Resultados Dos 130 recém-nascidos, 61 eram do sexo masculino e 69 do sexo feminino. A mediana do peso foi de 3,3 kg e da altura de 49 cm. Houve diferença significativa entre o peso e a medida da distância entre o canto do olho e a comissura labial do lado direito e esquerdo (ex-ch). Não foi encontrada diferença significativa das medidas orofaciais com sexo e altura. Conclusão Não houve diferença nas medidas antropométricas orofaciais de recém-nascidos a termo quando comparadas com sexo e altura; porém, quando comparadas com peso, há diferença nas medidas da distância entre o canto do olho e a comissura labial do lado direito e esquerdo.

ABSTRACT Purpose To compare orofacial anthropometric measurements, with weight, height and sex of newborns. Methods Observational cross-sectional study carried out with 130 newborns on exclusive breastfeeding. Data collection was performed by properly trained and calibrated speech therapists. The orofacial measurements of the newborns were performed with flexible and transparent ruler 10 cm long, in the following segments: heights of the upper third(tr-g), the middle third(g-sn) and the lower third on the face (sn-gn); filter height (sn-Is), distance between the corner of the eye and the labial commissure on the right and left side (ex-ch). Weight and height measurements were collected from the newborns' medical records. The data were submitted to statistical analysis, using the Mann-Whitney test, adopting a significance level of 5%. Results Of the 130 newborns, 61 were male and 69 female. The median weight was 3.3 kg and the median height was 49 cm. There was significant difference between weight and measurement distance between the corner of the eye and the left and right labial commissure (ex-ch). There was no significant difference in orofacial measurements with sex and height. Conclusion There was no difference in orofacial anthropometric measurements of full-term newborns when compared with sex and height; however, when compared to weight, there is a difference in the measurements of the distance between the corner of the eye and the labial commissure on the right and left side.

RESUMO

Abstract Introduction Ideal body weight calculation is used in critical medicine for drug dosing and setting ventilation parameters. However, the suggested and used equations were designed on the basis of anthropometric variables that do not represent the Latin American population. Objective To map and present the current evidence on the equations used to calculate ideal weight in patients on mechanical ventilation in intensive care units in Latin America. Material and Methods Exploratory review using the Joanna Briggs Institute method conceived by Arskey / O'Malley. A search was performed in the BVS, LILLACS, REDALYC, Ovid, Google Scholar and Scielo databases using keywords and MeSH terms in Spanish, English, and Portuguese, with no time limitation. The results are presented in descriptive tables. Results Overall, 1126 studies were identified and 1120 were excluded; 6 studies were reviewed and 3 additional studies were identified through a manual search. The studies were published in Chile, Brazil, Mexico, Ecuador, and Peru. In 89%, the ARDS Network equation was used to calculate tidal volume. Acute respiratory distress syndrome was the most reported pathology (33%). Conclusions Adult intensive care units in Latin America use the equation suggested by the ARDS Network, which was designed in a population with different anthropometric characteristics.

RESUMO

ABSTRACT The assessment of the nutritional status of hospitalized patients is fundamental to the establishment of the diagnosis. For bedridden patients, however, it is not possible to determine simple measures, such as weight and height, which are the most widely used variables for nutritional assessments. Objective: Compare real and estimated anthropometric measures in hospitalized patients. Methods: A cross-sectional study was conducted with adult (>18 years of age) and senior patients (>60 years of age) admitted for clinical or surgical treatment in the general surgery infirmary of Governador Paulo Guerra Restauração Hospital. Data (sex, age, clinical diagnosis, real weight, real height, body mass index, knee height and arm circumference) were collected using nutritional follow-up charts and tabulated using Excel 2016. Statistical analyses were performed in SPSS® version 21.0. Results: One hundred and twenty patients participated in the study (median age: 55 years). Most were adults (73.3%) and women (53.3%). The mean differences in weight between the estimated and real measures were statistically significant (p=0.000), with an overestimation of this variable. Regarding height, the estimated values differed significantly from the real values in both men and women (p<0.000) and the difference was larger among the seniors (mean: -0.072). No significant difference was found between the real and estimated body mass index (p= 0.44). Conclusion: In the comparison of methods for estimating weight and height to real measures, a tendency was found to overestimate these body measures.

RESUMEN La evaluación del estado nutricional de los pacientes hospitalizados es esencial para establecer su diagnóstico. Sin embargo, para los pacientes postrados en cama, no se pueden realizar medidas sencillas como el peso y la altura, que son las más utilizadas para el diagnóstico nutricional. Objetivo: Comparar mediciones antropométricas reales y estimadas en pacientes hospitalizados. Metodología: Estudio transversal, que incluye pacientes adultos (>18 años) y personas mayores de 60 años, ingresados para tratamiento clínico o quirúrgico en la sala de cirugía general del Hospital da Restauração Governador Paulo Guerra. Los datos (sexo, edad, diagnóstico clínico, peso real, altura real, índice de masa corporal, altura de la rodilla y circunferencia del brazo) se recopilaron mediante los formularios de monitoreo nutricional y se tabularon en el software Excel 2016. Los análisis estadísticos se realizaron con SPSS®, versión 21.0. Resultados: 120 pacientes con mediana de 55 años, en su mayoría adultos (73,3%) y mujeres (53,3%). Las diferencias promedio entre las mediciones estimadas y reales fueron estadísticamente significativas, con sobreestimación del peso (p<0,0001). Con respecto a la altura, fue posible identificar que las medidas estimadas diferían significativamente (p<0,0001) de las reales para hombres y mujeres, y que esta variación era aún mayor entre los ancianos (media: -0,072). No hubo diferencias estadísticamente significativas entre el índice de masa corporal real y el estimado (p= 0,44). Conclusión: Al comparar las metodologías para estimar el peso y la altura con las mediciones reales, fue posible observar una tendencia de los métodos a sobreestimar estas mediciones corporales.

RESUMO

RESUMO: Objetivo: Avaliar a validade da massa corporal e da estatura autorreferidas em adolescentes, adultos e idosos segundo sexo, idade, nível de atividade física no lazer, estado nutricional e fatores de risco cardiometabólicos. Métodos: Participaram do estudo 856 sujeitos, com 12 anos ou mais, que responderam ao Inquérito de Saúde de São Paulo (ISA-2015) e que possuíam a massa corporal e a estatura autorreferidas e aferidas. Com base no índice de massa corporal, realizou-se uma classificação do estado nutricional de acordo com critérios padronizados para cada fase da vida. A validade das medidas autorreferidas foi examinada usando o coeficiente de correlação intraclasse, Bland-Altman e o teste t pareado. Utilizaram-se regressões lineares para elaborar os coeficientes de calibração, e realizaram-se testes de sensibilidade e especificidade. Resultados: Os principais resultados apontam que os valores de massa corporal e estatura autorreferidas tendem a ser bem similares aos aferidos, apesar de algumas exceções. Para os adolescentes, notou-se uma subestimação da estatura, ao passo que, para os idosos, houve superestimação. Com relação à massa corporal, houve consistente subestimação da medida autorreferida entre as mulheres. Entre os homens que praticavam menos de 150 minutos semanais de atividade física no lazer, notou-se superestimação do índice de massa corporal. O processo de calibração das medidas autorreferidas tornou-as mais concordantes com as medidas aferidas, aumentando a sensibilidade na classificação do estado nutricional entre as mulheres e a especificidade entre os homens. Conclusões: As medidas autorreferidas de estatura, massa corporal e índice de massa corporal forneceram medidas válidas e confiáveis, apresentando melhoras substanciais após a calibração.

ABSTRACT: Objective: To evaluate the validity of self-reported body mass and height measurements in adolescents, adults and older adults according to sex, age, leisure-time physical activity level, nutritional status, and cardiometabolic risk factors. Methods: The study included 856 subjects, aged 12 years or older, who participated in the São Paulo Health Survey (ISA-2015) and who had their body mass and height measured and self-reported. Based on the Body Mass Index (BMI), a classification of nutritional status was made according to standardized criteria for each phase of life. The validation of self-reported data was examined by the Intraclass Correlation Coefficient, Bland-Altman and paired T-Test. Linear regression models were used to estimate the calibration coefficients, and sensitivity and specificity tests were performed. Results: Self-reported body mass and height values tend to be very similar to measured values, with a few exceptions. For the adolescents, an underestimation of height was noted, while for the older adults, an overestimation. There was a consistent underestimation of self-reported body mass among women, and an overestimation of BMI among men who practiced less than 150 minutes of physical activity per week during leisure time. The calibration process of self-reported measures made them more consistent with the values measured, increasing the sensitivity in the classification of nutritional status among women and the specificity among men. Conclusions: Self-reported measures of height, body mass and BMI provided valid and reliable measures, presenting a substantial improvement after calibration.

RESUMO

ABSTRACT Objective: To measure the Achilles tendon length, thickness and cross-sectional area in asymptomatic adult Saudi participants and to investigate the possible changes in these measurements based on their different ages and body height. Methods: The prospective cohort study was done between January 2014 and March 2015. A total of 200 asymptomatic participants with 175 males (87.5%) and 25 females (12.5%) between the ages of 14 and 65 years, with the mean age of 25 ± 1.5 years, were scanned at two radiology departments. Ultrasound (US) scans for the Achilles tendons were performed using a Hitachi (EZU-MT30-S1 HI Vision Avius, Hitachi, Japan) US machine. Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) was used to analyse the results. Results: There was no significant difference in the length, cross-sectional area and thickness of the Achilles tendons among the participants of different ages; however, the cross-sectional area of Achilles tendons of the older participants (≥ 47 years) was higher than that of the participants of the younger age groups. Moreover, there was no correlation between the length, cross-sectional area, and thickness of the Achilles tendons and their body heights; however, the participants of ≥ 153 cm in height showed an increase in their Achilles tendon cross-sectional areas. Conclusion: Ultrasound is a useful imaging tool in the assessment of the Achilles tendons. The normal variations of the tendon morphological characteristics should be considered in the clinical diagnosis. Additional studies on the correlations among the Achilles tendon length, thickness and cross-sectional areas of ethnicity of the participants in Saudi Arabia are suggested.

RESUMO

Es innegable la necesidad de contar con curvas estándar de tamaño al nacer y crecimiento para evaluar y contribuir a orientar las acciones en la atención del neonato. Durante muchos años, se utilizaron las referencias de Lejarraga y Fustiñana, que fueron progresivamente reemplazadas por las de Fenton y Kim.Recientemente, el proyecto INTERGROWTH-21st construyó estándares de crecimiento prescriptivo para evaluar el tamaño al nacer desde las 33 semanas de edad gestacional, referencias para evaluar el tamaño al nacer desde las 24 a las 32,6 semanas de edad gestacional y curvas para el seguimiento longitudinal del crecimiento de recién nacidos pretérmino desde las 27 semanas de edad gestacional. Los Comités de Crecimiento y Desarrollo y de Estudios Feto-neonatales de la Sociedad Argentina de Pediatría, en conjunto con la Secretaría de Gobierno de Salud de la Nación, acordaron recomendar el reemplazo de las curvas de Fenton y Kim por las de INTERGROWTH-21st

It is unquestionable the need to have standards of size at birth and growth to evaluate and contribute to guide the actions in the care of the newborn. For many years the references of Lejarraga and Fustiñana were used, progressively replaced by those of Fenton and Kim. However, recently, the INTERGROWTH-21st project has developed prescriptive growth standards to evaluate the size at birth from 33 weeks of gestational age, references from 24 to 32.6 weeks of gestational age, and curves for postnatal growth from 27 weeks of gestational age onward. The Growth and Development and Neonatal Fetal Studies Committees of the Argentine Society of Pediatrics in conjunction with the Secretary of National Government of Health agreed to recommend the replacement of the Fenton and Kim curves with those of INTERGROWTH-21st.
