The Food and Nutrition Surveillance System (SISVAN) allows the monitoring of anthropometric data and food consumption markers of users of Primary Care of the Unified Health System of all stages of life. Objective: To estimate the prevalence of thinness, excess weight and short stature in schoolchildren aged 5 to 9 years in the state of Goiás and regional health centers (RS). Methods: This is an descriptive ecological study, based on secondary data recorded in SISVAN in the last 5 years. Anthropometric assessment was performed using height-for-age and body mass index-for-age indicators. Results: There was a low prevalence of thinness (5.7%) and short stature (6.1%) and a high prevalence of overweight (34.8%) among the children evaluated, being higher in RS Entorno Norte in the first two parameters and in the RS Rio Vermelho in the last parameter. Regarding the evolution of prevalence in the last five years, an increase in excess weight was observed. Conclusion: The growing increase in overweight in schoolchildren aged 5 to 9 years was highlighted, indicating the importance of monitoring nutritional status data, as well as attention to the development of actions aimed at reversing the scenario found

Sobrecrecimiento lateral aislado - caracterización auxológica y clínico-radiológica de una cohorte de 76 casos de un único centro / Isolated lateralized overgrowth: clinical, radiological, and auxological characteristics of a single-site cohort of 76 cases

Introducción. El sobrecrecimiento lateral aislado (SLA), antes denominado hemihiperplasia/ hemihipertrofia, se refiere al sobrecrecimiento corporal lateral en ausencia de un patrón reconocible de malformaciones o síndromes genéticos. El objetivo fue analizar el crecimiento y las características clínico-radiológicas de pacientes con SLA en seguimiento en un hospital de tercer nivel en Argentina entre 1993 y 2020. Población y métodos. Estudio retrospectivo, observacional, de una cohorte de pacientes con SLA. Resultados. Se incluyeron 76 casos, 41 varones. Mediana de años de seguimiento: 5,85 (rango intercuartílico [RIC] 2,60-10,96), máximo 15,76 años. Cuarenta y ocho de 76 pacientes presentaron sobrecrecimiento en más de un segmento corporal (SLA complejo). El puntaje Z promedio de peso al nacer de niñas de término con SLA complejo fue +0,51 (desviación estándar [DE] 0,91) (p 0,022). El crecimiento en estatura de la mayoría de los niños se ubicó entre los centilos 50 y 97 de la población de referencia. La mediana de asimetría de longitud de miembros inferiores fue 1,5 cm (RIC 1,01-2,2) en pacientes con tratamiento médico y 3,70 cm (RIC 2,953,98 cm) en aquellos que requiriero epifisiodesis. El 75 % mostró una progresión de la asimetría menor o igual a 2 cm. Ocho casos presentaron asimetría renal mayor o igual a 1 cm; 2 casos presentaron nefroblastoma: edad promedio al diagnóstico 0,75 años. Conclusiones. El crecimiento prenatal de niños con SLA es normal, excepto en niñas con SLA complejo en quienes tiende a estar aumentado. La estatura promedio se ubica en centilos altos con crecimiento normal. Se recomienda realizar cribado de tumores embrionarios en este grupo de niños.

Introduction. Isolated lateralized overgrowth (ILO), formerly referred to as hemihyperplasia/hemihypertrophy, is the overgrowth of one-half of the body to its contralateral in the absence of a recognizable pattern of malformations or genetic syndromes. Our objective was to analyze the growth clinical and radiological characteristics of patients with ILO under follow-up in a tertiary care hospital in Argentina between 1993 and 2020. Population and methods. Retrospective, observational, single cohort study of patients with ILO. Results. A total of 76 cases were included; 41 were males. Median years of follow-up: 5.85 (interquartile range [IQR]: 2.60­10.96), maximum: 15.76 years. Forty-eight of 76 patients had overgrowth compromising more than 1 body segment (complex ILO). The mean birth weight Z-score of term girls with complex ILO was +0.51 (standard deviation [SD]: 0.91) (p 0.022). Most children grew between the 50th and 97th centile of the Argentinian population height reference. The median leg length discrepancy was 1.5 cm (IQR: 1.01­2.2) in patients receiving medical treatment and 3.70 cm (IQR: 2.95­3.98 cm) in those who required epiphysiodesis. Progression of discrepancy ≤ 2 cm was observed in 75% of cases. Renal asymmetry ≥ 1 cm was observed in 8 cases; Wilms tumor was noted in 2 cases: mean age at diagnosis: 0.75 years. Conclusions. Prenatal growth of children with ILO is normal, except in girls with complex ILO, in whom it tends to be increased. The average height of boys and girls tends to be located in high centiles with normal growth over time. Embryonal tumor screening is recommended in this group of children.

Lifestyle, psychological well-being, and body mass index of indigenous women

Lifestyle, psychological well-being, and body mass index of indigenous women. Introduction. Obesity is more common in women and has also been found to be present in indigenous populations. During university studies, obesity-related lifestyles are in the process of consolidation, and although this is known, research is limited to addressing physical activity and diet, ignoring other lifestyle components, such as life appreciation. Additionally, there is a need to corroborate whether psychological well-being contributes to excess weight in indigenous women. Objective. To determine whether there is an association between lifestyle, psychological well-being, and body mass index (BMI) in indigenous women. Materials and methods. A cross-sectional study was conducted among 110 female Zapotec university students in Juchitán, Oaxaca, Mexico. The Psychological Well-Being Scale, the Healthy Lifestyle Scale for University Students, and a questionnaire about personal data were used. Body weight and height were measured to calculate BMI. Results. There was a negative correlation between BMI, self-acceptance (r = -0.33; p < 0.01), and life appreciation (r = -0.22; p < 0.05). Positive correlations were found between lifestyle and psychological well-being dimensions, with the strongest correlations being observed between life appreciation and purpose in life (r = 0.55) and self-acceptance (r = 0.48). The multivariable models determined that life appreciation and self-acceptance are associated with BMI. Conclusion. Life appreciation and self-acceptance are predictors of BMI and are even more strongly associated than exercise and nutrition behaviors(AU)

La obesidad es más frecuente en mujeres, aún en poblaciones indígenas. Durante los estudios universitarios, los estilos de vida relacionados con la obesidad se encuentran en proceso de consolidación, y aunque esto es conocido, las investigaciones se limitan a abordar la actividad física y la dieta, ignorando otros componentes del estilo de vida, como la apreciación por la vida. Adicionalmente, es necesario corroborar si el bienestar psicológico contribuye al exceso de peso en mujeres indígenas. Objetivo. Determinar si existe asociación entre los estilos de vida, el bienestar psicológico y el Índice de Masa Corporal (IMC) en mujeres indígenas. Materiales y métodos. Se realizó un estudio transversal en 110 mujeres zapotecas estudiantes universitarias en Juchitán, Oaxaca, México. Se utilizó la escala de bienestar psicológico, la escala de estilos de vida saludables para estudiantes universitarias y un cuestionario sobre datos personales. Se midió el peso corporal y la estatura para calcular el IMC. Resultados. Hubo correlación negativa entre el IMC, la autoaceptación (r=-0,33; p<0,01) y la apreciación por la vida (r=-0,22; p<0,05). Se encontraron correlaciones entre las dimensiones de estilos de vida y las dimensiones de bienestar psicológico: las correlaciones más fuertes se observaron entre apreciación por la vida y propósito en la vida (r 0 0.55) y autoaceptación (r = 0.48). La apreciación por la vida y la autoaceptación son factores predictores del IMC. Conclusión. La apreciación por la vida y la autoaceptación son predictores del IMC, incluso más fuertemente asociados que el ejercicio físico y la alimentación(AU)

Redução do déficit de estatura e a compra de alimentos da agricultura familiar para alimentação escolar no Brasil / Reduction of stature deficit and purchase of family agriculture produce for school meals in Brazil / Reducción del déficit de estatura y de la agricultura familiar en la alimentación escolar en Brasil

O objetivo do artigo é analisar o efeito da compra direta de alimentos da agricultura familiar para alimentação escolar sobre o déficit de estatura em crianças menores de cinco anos, entre 2013 e 2017, no Brasil. O método utilizado é o estudo ecológico e longitudinal, em que a coleta de dados ocorreu em diferentes bancos de dados. A análise foi realizada por meio do teste t para amostras independentes, a fim de comparar as médias entre as variáveis déficit de estatura e compras da agricultura familiar. Além disso, uma análise multivariável foi feita por meio da regressão linear múltipla. Verificou-se uma diferença de médias na prevalência do déficit de estatura significativa entre os municípios que compraram menos de 30% e aqueles que adquiriram 30% ou mais de alimentos da agricultura familiar para alimentação escolar, com 1,47 pontos de diferença. O modelo de regressão linear mostrou que a cada ponto percentual de aumento na compra de alimentos da agricultura familiar para a alimentação escolar pelo município, haverá, em média, uma diminuição 0,55 pontos na prevalência do déficit de estatura, independentemente das demais variáveis. Assim, conclui-se que a compra de alimentos da agricultura familiar para alimentação escolar no Brasil pode contribuir para a redução da prevalência do déficit de estatura em crianças menores de cinco anos.

The objective of this work is to analyze the effect of direct purchase of food from family farms for school meals on the deficit of stature in children under 5 years of age between 2013 and 2017 in Brazil. Method: Ecological and longitudinal study in which data collection occurred in different databases. The analysis was performed using the t-test for independent samples in order to compare the means between the variables stature deficit and purchases from family agriculture. In addition, a multivariable analysis was conducted through multiple linear regression. Results: There was a difference in means in the prevalence of significant stature deficit between the municipalities that bought < 30% and ≥30% of food from family farms for school feeding, with 1.47 points of difference. The linear regression model showed that for each percentage point of increase in the purchase of food from family farms for school feeding by the municipality, there will be on average a decrease of 0.55 points in the prevalence of stature deficit, independent of the other variables. Conclusion: the purchase of food from family agriculture for school feeding in Brazil may contribute to the reduction of the prevalence of stature deficit in children under five years old.

Conclusión: la compra de alimentos de las granjas familiares para la alimentación escolar en el Brasil puede contribuir a reducir la prevalencia del déficit de estatura en los niños menores de cinco años.

Body height and its estimation utilizing hand length measurements in Montenegrin: national survey / Altura del cuerpo y su estimación utilizando medidas de longitud de la mano en montenegrino: encuesta nacional

SUMMARY: The purpose of this research is to determine a regression equation for estimation of stature from hand length measurements. This research was carried out on 1001 subjects (504 male and 497 female) among the population of Montenegrin adolescents. The stature and hand length measurements were taken according to the ISAK protocol, and the data were analyzed statistically; the relationships between stature and hand length measurements were derived using simple correlation. A comparison of the means of hand length measurements between sex was performed using a t-test, while a linear regression analysis was employed to examine the extent to which hand length t measurements can reliably predict stature. The results of this research study confirmed that hand length reliably predicts stature in both sexes of Montenegrin adolescents and revealed a very useful finding for physical anthropologists and experts from related fields.

RESUMEN: El propósito de esta investigación fue determinar una ecuación de regresión para la estimación de la estatura a partir de medidas de la longitud de la mano. Este estudio se llevó a cabo en 1001 sujetos (504 hombres y 497 mujeres) entre la población de adolescentes montenegrinos. Las medidas de estatura y longitud de mano se tomaron de acuerdo con el protocolo ISAK, y los datos se analizaron estadísticamente; las relaciones entre las medidas de estatura y longitud de la mano se derivaron mediante correlación simple. Se realizó una comparación de las medias de las medidas de la longitud de la mano entre sexos mediante una prueba t, mientras que se empleó un análisis de regresión lineal para examinar hasta qué punto las medidas t de la longitud de la mano pueden predecir la estatura de forma fiable. Los resultados de este estudio confirmaron que la longitud de la mano predice de manera confiable la estatura en adolescentes montenegrinos de ambos sexos y reveló un hallazgo muy útil para antropólogos físicos y expertos en áreas relacionadas.

Association between socioeconomic and nutritional factors and height of Brazilian adolescents: results from the Study of Cardiovascular Risk in Adolescents / Associação entre fatores socioeconômicos e nutricionais e altura de adolescentes brasileiros: resultados do Estudo de Riscos Cardiovasculares em Adolescentes / Asociación entre los factores socioeconómicos y nutricionales y la estatura de los adolescentes brasileños: resultados del Estudio de Riesgo Cardiovascular en Adolescentes

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).

Effect of glucocorticoid therapy on long-term growth and development of children with bronchiolitis / 中国当代儿科杂志

OBJECTIVES@#To explore the effect of glucocorticoid therapy on the growth and development of children with bronchiolitis.@*METHODS@#A total of 143 children with bronchiolitis who were treated with glucocorticoids from February 2017 to March 2018 were enrolled. The medical data were retrospectively collected, including height, weight, course of the disease, and diagnosis and treatment plan at initial admission. After three years of treatment, physical development indices were measured, growth and development were evaluated by Z-score, and related hematological parameters were measured, including osteocalcin, serum phosphorus, and insulin-like growth factor-1.@*RESULTS@#As for the children with bronchiolitis, the incidence rates of growth retardation and obesity increased significantly after three years of glucocorticoid therapy (P<0.05). The children treated with glucocorticoids for ≥29 days showed a significantly higher incidence rate of obesity than those treated with glucocorticoids for <29 days (P<0.05), while nebulized glucocorticoid treatment had no effect on the growth and development (P>0.05). Compared with the children with growth retardation, the children with normal development had significantly higher levels of serum phosphorus and insulin-like growth factor-1 (P<0.05).@*CONCLUSIONS@#Glucocorticoid therapy can adversely affect long-term growth and development in children with bronchiolitis.

Searching chromosome mosaicisms in 45, X Turner syndrome: how relevant is it?

ABSTRACT Objective: To investigate the presence of chromosome mosaicism, especially for the presence of Y derived material in 45,X women with Turner syndrome (TS). Materials and methods: FISH and PCR were performed for the presence of chromosome mosaicism and Y-derived-material and genetic findings were correlated to clinical data. Results: Thirty-one participants were enrolled: 18 (58%) had chromosome mosaicisms (FISH), Y-derived material was found in 2. Yet, SRY primer was found with PCR in only one of them and DYZ3 was not found. The most frequent clinical findings were short or webbed neck (81,82%), high-arched palate (78%), breast hypertelorism, e cubitus valgus and genu valgus (57.6%, both), short fourth metacarpals (46.9%), epicanthic folds (43.8%), shield chest (43.8%), lymphedema (37.5%), and low set ears (34.4%). Both patients with Y-derived-material had primary amenorrhea, dyslipidemia and reached the height of 150 cm despite not treated with recombinant growth hormone (GHr). One of them showed 26% of leukocytes with Y-derived material and few clinical findings. Conclusions: FISH techniques proved efficient in detecting chromosome mosaicisms and Y-derived material and searching in different tissues such as mouth cells is critical due to the possibility of tissue-specific mosaicism. Phenotypical variance in TS may be a signal of chromosome mosaicisms, especially with the presence of Y-derived material.

Associação entre insatisfação com a imagem corporal e indicadores antropométricos de obesidade em escolares do sul do brasil / Association between body image dissatisfaction and anthropometric indicators of obesity in students from southern brazil

O objetivo do presente estudo foi investigar a associação entre a insatisfação com a imagem corporal, por excesso de peso e pela magreza, e diferentes indicadores antropométricos de obesidade em adolescentes do sul do Brasil. Caracterizou-se com um estudo transversal, realizado na cidade de Criciúma ­ SC, com 575 adolescentes de 11 a 17 anos, de ambos os sexos. A imagem corporal foi avaliada por meio de escala de silhuetas. Os indicadores antropométricos de obesidade Índice de Massa Corporal, Relação Cintura-Estatura, Perímetro da Cintura e Índice de Conicidade foram avaliados conforme protocolo da Sociedade internacional para o Avanço da Cineantropometria. Adolescentes do sexo masculino, de 11 a 13 anos insatisfeitos pela magreza, apresentaram menores chances de ter Relação Cintura-Estatura elevada (RC: 0,1; IC95%: 0,04 - 0,51) e maiores chances de ter Índice de Conicidade elevado (RC: 4,4; IC95%:1,28-15,20) quando comparados com adolescentes satisfeitos com a imagem corporal. Adolescentes do sexo feminino, de 11 a 13 anos insatisfeitas pela magreza, apresentaram menores chances de ter Índice de Massa Corporal (RC: 0,1; IC95%: 0,02 - 0,58) e Índice de Conicidade (RC: 0,2; IC95%: 0,05 - 0,94) elevados e maiores chances de ter Relação Cintura-Estatura elevada (RC: 23,6; IC95%: 3,35-166,85) quando comparadas às adolescentes satisfeitas com a imagem corporal. Concluiu-se que existe associação entre a imagem corporal e indicadores antropométricos de obesidade para adolescentes de 11 a 13 anos, principalmente nos insatisfeitos pela magreza. No sexo masculino, distintos indicadores antropométricos de obesidade abdominal trazem interpretações distintas na associação com a imagem corporal. No sexo feminino, indica distorção da própria imagem corporal, que pode levar as adolescentes a adotarem comportamentos alimentares inadequados, levando à riscos à sua saúde. (AU)

The aim of the present study was to investigate the association between body image dissatisfaction due to overweight and thinness and different anthropometric indicators of obesity in adolescents from southern Brazil. Characterized as a Cross - sectional study conducted in the city of Criciúma - SC, with 575 adolescents aged 11-17 years of both sexes. Body image was assessed by a silhouette scale. Anthropometric indicators of obesity body mass index, waist-to-height ratio, waist circumference and conicity index were evaluated according to the International Society for the Advancement of Kinantropometry protocol. Male adolescents aged 11-13 years dissatisfied due to thinness, were less likely of having high waist-to-height ratio (OR: 0.1; 95% CI: 0.04 - 0.51) and more likely of having elevated conicity index (OR: 4.4; 95% CI: 1.28-15.20) when compared to adolescents satisfied with their body image. Female adolescents aged 11-13 years dissatisfied due to thinness were less likely of having high body mass index (OR: 0.1; 95% CI: 0.02 - 0.58) and conicity index (OR: 0.2; 95% CI: 0.05 - 0.94) and more likely of having high waist-to-height ratio (OR: 23.6; 95% CI: 3.35-166.85) when compared to adolescents satisfied with their body image. Concluded that there is an association between body image and anthropometric indicators of obesity for adolescents aged 11-13 years, especially those dissatisfied due to thinness. In males, different anthropometric indicators of abdominal obesity bring different interpretations in association with body image. In females, it indicates distortion of their own body image, which can lead adolescents to adopt inappropriate eating behaviors, leading to health risks. (AU)

Influence of sodium intake and sociodemographic, lifestyle and anthropometric variables on blood cholesterol of hypertensive women

The restriction of sodium intake, one of the pillars of antihypertensive treatment, has been associated with the increase in cholesterol levels. Given this, we hypothesize that a sodium intake restriction may increase cholesterol levels in hypertensive women. The present study aimed to evaluate the influence of sodium intake, sociodemo-graphic, lifestyle and anthropometric variables on the blood cholesterol levels of hypertensive women. This was a cross-sectional study with hypertensive and nondiabetic women aged 20 to 59 years, recruited from the primary healthcare units of Maceio, Alagoas, in the Brazilian Northeast. Sodium intake was estimated by the 24-hour urinary excretion of sodium; and blood cholesterol was estimated by capillary blood. Age (years), education level (<4 or ≥4 years), race (white or nonwhite), smoking and alcohol consumption were evaluated. The weight, height and waist circumference were measured and body mass index, conicity index and waist-to-height ratio were quantified. The percentage of body fat was measured using a tetrapolar bioelectrical impedance device. The relationship between blood cholesterol and other variables was assessed by multiple regression analysis. A significance level of 5% was used in the final model. This study included 165 hypertensive women. In linear regression, blood cholesterol was directly proportional to age (p<0.001), education level (p=0.01) and race (p=0.04). These variables, as well as sodium intake (p = 0.07) and conicity index (p = 0.12), were included in the multiple regression analysis. Sodium intake (p=0.03) and age (p=0.001) were related, in an inverse and a direct way, respectively, to the blood choles-terol in the hypertensive women studied. (AU)

ção da ingestão de sódio, um dos pilares do tratamento anti-hipertensivo, tem sido associada ao aumen-to dos níveis de colesterol. Diante disso, levantou-se a hipótese de que a ingestão de sódio influencia os níveis de colesterol de mulheres hipertensas, independentemente de outros fatores associados. Trata-se de um estudo transversal realizado com mulheres hipertensas e não diabéticas, na faixa etária entre 20 e 59 anos, recrutadas em unidades básicas de saúde de Maceió, Alagoas, situada no Nordeste do Brasil. A ingestão de sódio foi estimada pela excreção urinária de sódio de 24 horas; e o colesterol sérico foi mensurado por coleta de sangue capilar. Foram ava-liados idade (anos), escolaridade (<4 ou ≥4 anos), raça (branca ou não branca), tabagismo e consumo de álcool. O peso, a estatura e a circunferência da cintura foram aferidos e o índice de massa corporal, índice de conicidade e razão cintura/estatura foram calculados. A porcentagem de gordura corporal foi medida usando um dispositivo de impedância bioelétrica tetrapolar. A relação entre o colesterol sérico e as outras variáveis em estudo foi avalia-da por meio de análise de regressão múltipla, adotando-se um nível de significância de 5% no modelo final. Este estudo incluiu 165 mulheres hipertensas. Na análise de regressão linear, o colesterol sérico foi relacionado à idade (p<0,001), escolaridade (p=0,01) e raça (p=0,04).

Height adjustment reduces occurrence of low bone mineral density in children and adolescents with HIV

SUMMARY OBJECTIVE: The aim of this study was to quantify the reduction of bone mineral density with and without height adjustment. METHODS: A cross-sectional study was performed with 69 Brazilian children and adolescents vertically infected by HIV. Bone mineral density was measured by dual-energy absorptiometry in the lumbar spine. Anthropometric, demographic, and clinical variables were analyzed. A specific calculator was used for height adjustment. RESULTS: The majority of participants (52.2%) were adolescents and did not present with immunological alterations (61%). Reduced bone mineral density (Z-score <-1) was present in 23.2% and low bone mass (Z-score <-2) in 5.8%. After height adjustment, these occurrences decreased to 11.6% and 0%, respectively. Patients with reduced bone mineral density had a higher mean age and lower body mass index than patients with normal bone mineral density. CONCLUSION: The occurrence of reduced bone mineral density decreased after adjustment for height.

Trends in body height, body weight, BMI, and nutrition status from 1979 to 1987: a measurement-based analysis of 10, 954 male adolescents from the municipality of Bijelo Polje / Tendencias en la altura corporal, el peso corporal, el IMC y el estado nutricional de 1979 a 1987: un análisis basado en mediciones de 10. 954 adolescentes varones del municipio de Bijelo Polje

SUMMARY: This study aimed to consolidate data regarding body height, body weight, body mass index, and nutrition status of the entire young male population from the Municipality of Bijelo Polje in order to estimate trends from 1979 to 1987. The sample of respondents includes 10,954 young males divided into nine groups. The measurement sample includes body height, body weight, and body mass index based on two previous measures. The descriptive statistics were expressed as a mean and standard deviation for each variable, while the analysis of nutrition status was done based on body mass index (underweight, normal weight, pre-obese, obese). The results showed that a secular trend in the observed study period is not visible regarding body height, body weight, and body mass index. The contribution of this study is reflected in the fact that there were no previously published data for this period and this municipality; the data can significantly aid in monitoring the secular trends throughout Montenegro.

RESUMEN: Este estudio tuvo como objetivo consolidar los datos sobre la altura corporal, el peso corporal, índice de masa corporal y el estado nutricional de toda la población masculina joven del Municipio de Bijelo Polje con el fin de estimar las tendencias de 1979 a 1987. La muestra de encuestados incluyó 10.954 hombres jóvenes divididos en nueve grupos. Las mediciones incluyeron la altura corporal, el peso corporal y el índice de masa corporal basado en dos medidas anteriores. Las estadísticas descriptivas se expresaron como media y desviación estándar para cada variable, mientras que el análisis del estado nutricional se realizó con base en el índice de masa corporal (bajo peso, peso normal, pre-obesidad, obesidad). Los resultados mostraron que una tendencia secular en el período de estudio observado no es visible con respecto a la altura corporal, el peso corporal y el índice de masa corporal. La contribución de este estudio está basada en que no existían datos publicados previamente para este período y en este municipio; los datos pueden ayudar significativamente a monitorear las tendencias seculares en todo Montenegro.

Body height and its estimation utilizing shoulder blade length measurements of Montenegrin adolescents of both sexes / La altura del cuerpo y su estimación utilizando medidas de la longitud de la escápula de adolescentes montenegrinos de ambos sexos

SUMMARY: The purpose of this research is to determine a regression equation for estimation of stature from shoulder blade length measurements. The sample in this research comprised 1001 adolescents, all of whom were in their final year of high school (504 males and 497 females) among the population of Montenegrin adolescents. The stature and shoulder blade length measurements were taken according to the ISAK protocol, and the data were analyzed statistically. Linear regression analysis determined the prediction of and shoulder blade length on the criterion variable a body height at the significance level of p <0.05. These relations are presented by using a scatter diagram (Fig. 2). Thereby, we obtained the coefficient of determination, the multiple correlation coefficients, the partial correlation coefficient, the regression, t-test and standardized beta coefficient. The research study confirmed that shoulder blade length reliably predicts stature in both sexes of Montenegrin adolescents and revealed a very useful finding for physical anthropologists and experts from related fields. It was confirmed that there is a correlation between shoulder blade length and body height (males: 34.3 %, females: 38.8 %). Therefore, shoulder blade length proves to be a reliable predictor for the actual body height estimates.

Se confirmó que existe una correlación entre la longitud del escápula y la altura del cuerpo (hombres: 34,3 %, mujeres: 38,8 %). Por lo tanto, la longitud del escápula demuestra ser un predictor confiable de las estimaciones de la altura corporal real.

Stature estimation from radiographic measurements in adult Anatolian population / Estimación de la estatura a partir de mediciones radiográficas en una población adulta de anatolia

SUMMARY: The purpose of the present study was to create a regression equation for measuring stature using measurements obtained from the long bone radiographs of adult individuals in Anatolian population. In this study, the maximum length measurements of the six long bones in the upper and lower limbs of 167 healthy individuals were determined from radiographic images. Single and multiple regression equations were created to predict the stature of the individuals from the maximum bone stature. From these equations, the standard error of estimate was determined in the range of 1.68-4.09 cm. As a result of this study, the obtained regression equations resulted in highly reliable and successful results in terms of predicting stature. These equations will provide convenient and predictive accuracy in the estimation of stature from skeletal remains obtained from societies that lived and living in Anatolia. Besides, we anticipate that it will guide researchers working in the fields of Forensic Anthropology, Forensic Medicine and Anatomy.

Avaliação de indicadores antropométricos de obesidade e a presença de comorbidades em participantes das ações do NASF do município de Candói, Paraná, Brasil / Evaluation of anthropometric indicators of obesity and the presence of comorbidities in participants of NASF actions in the city of Candói, Paraná, Brazil

Introdução: alguns indicadores antropométricos se caracterizam por serem facilmente aplicados e amplamente utilizados para a avaliação da obesidade e distribuição da gordura corporal, constituindo um dos primeiros passos para identificar risco inicial à saúde. Objetivo: avaliar e identificar a frequência de obesidade geral e abdominal por meio de indicadores antropométricos e verificar a presença de comorbidades em indivíduos que participaram das reuniões educativas e atividades do NASF do Município de Candói, Paraná. Metodologia: trata-se de um estudo quantitativo e transversal, com aplicação de questionário para conhecer as comorbidades e caracterizar a amostra por meio da aferição de peso, estatura e circunferência da cintura (CC), além da determinação do índice de massa corporal (IMC) e relação cintura-estatura (RCE). Nas análises de associação, utilizou-se o teste de qui-quadrado seguido do cálculo das razões de chance (RC). Resultados: a maior parte da amostra foi classificada como sobrepeso/obesidade (69,2%), com base no IMC, e apresentou elevados índices de obesidade abdominal pela CC e RCE. Os valores de CC aumentados foram observados em 83,01% dos pacientes. Em relação a RCE, o valor adequado foi verificado em apenas 14,5% dos participantes. As associações entre os índices antropométricos e as demais variáveis mostraram diferenças estatisticamente significativas em relação à idade dos participantes, revelando maior frequência de RCE aumentada em pacientes com 60 anos ou mais (RC = 8,53, p = 0,01). Dentre as comorbidades, o destaque foi a presença da hipertensão arterial sistêmica. Conclusão: além das elevadas frequências de obesidade geral, obesidade abdominal e da presença de comorbidades, como a hipertensão arterial sistêmica, a RCE foi o índice antropométrico capaz de sugerir risco cardiometabólico aumentado em idosos. Neste sentido, este estudo mostra a capacidade de caracterizar os usuários do sistema público de saúde com potencial para o desenvolvimento de doença cardiovascular através do uso de ferramentas antropométricas de baixo custo, e assim, poder dar suporte para ações corretivas a nível de políticas públicas municipais.

Introduction: some anthropometric indicators are characterized by being easily applied and widely used to assess obesity and body fat distribution, constituting one of the first steps to identify initial health risk. Objective: to assess and identify the frequency of general and abdominal obesity using anthropometric indicators and to verify the presence of comorbidities in individuals who participated in the NASF educational meetings and activities in the city of Candói, Paraná. Methodology: this is a quantitative and cross-sectional study, with the application of a questionnaire to find out about comorbidities and to characterize the sample by measuring weight, height and waist circumference (WC), in addition to determining the body mass index (BMI) and waist-height ratio (RCE). In the association analyzes, the chi-square test was used followed by the calculation of the odds ratios (CR). Results: most of the sample was classified as overweight/obesity (69.2%), based on BMI, and showed high rates of abdominal obesity by WC and WHR. The increased WC values were observed in 83.01% of the patients. Regarding CER, the adequate value was verified in only 14.5% of the participants. The associations between the anthropometric indices and the other variables showed statistically significant differences in relation to the age of the participants, revealing a higher frequency of increased CER in patients aged 60 years or older (RC = 8.53, p = 0.01). Among the comorbidities, the highlight was the presence of systemic arterial hypertension. Conclusion: in addition to the high frequencies of general obesity, abdominal obesity and the presence of comorbidities, such as systemic arterial hypertension, the CER was the anthropometric index capable of suggesting increased cardiometabolic risk in the elderly. In this sense, this study shows the ability to characterize users of the public health system with the potential for the development of cardiovascular disease through the use of low-cost anthropometric tools, and thus be able to support corrective actions at the level of municipal public policies. .

Relationship between Knee Symptoms and Biological Features in Recreational Runners / Relação entre sintomatologia no joelho e as características biológicas em corredores recreacionais

Abstract Objective The main objective of the present study was to compare the subjective perception of pain and symptoms of anterior knee pain with the different body mass index (BMI) classifications. The secondary objective was to verify the association between biological and anthropometric variables with the results of subjective questionnaires. Methods A total of 126 recreational runners from both genders, aged between 20 and 59 years old, were recruited. Data regarding the biological variable (age), anthropometric variables (weight, height), visual analog scale (VAS), and Lysholm and Kujala questionnaires scores were collected. Information was obtained with a digital platform, available through a single link, allowing volunteers to answer these questions using electronic devices. Normality was verified by the Shapiro-Wilk test. T-tests and Wilcoxon tests were used to compare mean values. The association between variables was determined by the Pearson linear correlation. Results There were significant differences in height between overweight and grade 1 obesity subjects (p = 0.029), in weight and BMI comparing normal weight subjects and both overweight and grade 1 obesity subjects (p < 0.001 and p < 0.05, respectively). An unclear significant correlation was observed between BMI values and specific questionnaires and subjective scale scores (p < 0.05). Conclusion Recreational runners who present high BMI values are more likely to experience knee pain than those with normal BMI values.

Resumo Objetivo O principal objetivo do presente estudo foi comparar a percepção subjetiva de dor e sintomas de dor anterior no joelho com as diferentes classificações de índice de massa corporal (IMC). O objetivo secundário foi verificar a associação entre as variáveis biológica e antropométrica com os resultados apresentados pelos sujeitos nos questionários subjetivos. Métodos Foram recrutados 126 corredores recreacionais de ambos os gêneros, com idades entre 20 e 59 anos. Foram coletados dados referentes à variável biológica idade, e as variáveis antropométricas peso e altura, além da escala visual analógica (EVA) e os questionários Lysholm e Kujala. As informações foram obtidas por meio de plataforma digital, disponibilizado em um único link, para que fossem respondidos através de dispositivos eletrônicos pelos próprios voluntários. A normalidade foi verificada por meio do teste Shapiro-Wilk. Foi utilizado o teste-T e o teste de Wilcoxon para comparação das médias. A associação entre as variáveis foi determinada pela correlação linear de Pearson. Resultados Houve diferença significativa entre a estatura do grupo sobrepeso e o grupo obesidade grau 1 (p = 0,029), e o peso do grupo peso normal para os grupos sobrepeso e obesidade grau 1 (p < 0,001), e entre as médias do IMC (p < 0,05). Foi observada correlação significativa não clara entre o IMC e os questionários específicos e a escala subjetiva (p < 0.05). Conclusão Os corredores recreacionais que possuem IMC acima dos valores de normalidade estão mais predispostos a apresentar dor no joelho do que aqueles com IMC normal.

Relationship between body mass index and waist-to-height ratio in childhood

SUMMARY OBJECTIVE: To evaluate whether there is an association between the body mass index z-score and waist-to-height ratio of children and adolescents. METHODS: This was a cross-sectional study conducted in a school in Santo André, SP, between June and August 2019. Body mass index was measured for all participants, adopting the z-score cutoff of +2 recommended by the World Health Organization. The waist-to-height ratio was determined in children over two years of age and considered abnormal when ≥0.5. The qualitative variables are presented as absolute numbers and percentages. To compare qualitative data, we used the χ2 test or Fisher's exact test. Pearson's test was applied to assess the correlation between BMI and waist-to-height ratio. The level of significance adopted was 5%. RESULTS: The body mass index was calculated for 518 children and the waist-to-height ratio for 473 children. Regarding body mass index, 60.6% of the participants had normal weight, 3.1% were underweight, and 36.3% were overweight. overweight (24.7%) and obesity (22.7%) were more prevalent in adolescents. The waist-to-height ratio was abnormal in 50.5% of the sample. There was an increasing association between body mass index and waist-to-height ratio with age, according to the Pearson correlation coefficients for the age groups <5 years (r=0.459; p<0.001), 5 to 10 years (r=0.687; p<0.001) and >10 years (r=0.805; p<0.001). CONCLUSION: There was a significant correlation between body mass index and waist-to-height ratio. This association was higher in adolescents. The waist-to-height ratio is easy to apply and may be useful as a predictor of cardiometabolic risk.

Introducción: la reducción de la capacidad oxidativa del músculo con el envejecimiento parece jugar un papel importante en la vejez disminuyendo hasta 50%. En zonas elevadas sobre el nivel del mar se producen cambios en la dinámica del oxígeno arterial que se relacionan con el metabolismo del músculo y la sarcopenia. Objetivos: determinar si hay relación entre el VO2pico y el porcentaje de masa muscular, nivel de actividad física e IMC, en adultos que habitan en regiones superiores a 2600 metros sobre el nivel del mar. Metodología: estudio descriptivo de tipo transversal, se incluyeron participantes sin sarcopenia mayores de 50 años, con mínimo un año de residencia en Bogotá, Colombia. Se excluyeron participantes con terapia de reemplazo hormonal, tensión arterial elevada durante la prueba, enfermedad coronaria, valvular o trastornos de la conducción. Se determinó el nivel de actividad física aplicando la encuesta Ainsworthy col, la composición corporal con bioimpedanciometría y VO2pico mediante ergoespirometría. Resultados: la muestra fue de 21 participantes. La mitad de lapoblación mostró VO2pico de 23.7 ml/k/min, IMC de 27.2g/m2 y porcentaje de masa muscular de 35.5%; hay baja correlación entre VO2pico y el porcentaje de masa muscular. La mitad de la población saludable tiene un VO2pico de 28.9 ml/k/min, sedentaria saludable 23.7 ml/k/min y sedentaria riesgosa 21.6 ml/k/min. Conclusiones: el presente estudio mostró que hay baja correlación entre el porcentaje de masa muscular y el VO2pico, sin embargo estos resultados pudieron estar influenciados por el tamaño de la muestra y otros factores.

Introduction: the decrease of muscle oxidative capacity with aging appears to play an important role in old age and is observed to decline by 50%. Changes in arterial oxygen dynamics related to muscle metabolism and sarcopenia are evidenced in high altitudes. Objectives: to determine if there is a relationship between VO2max and muscle mass, physical activity and BMI, in adults living in altitudes over 2600 MAMSL. Methodology: descriptive cross-sectional study in older than 50 years subjects without sarcopenia, who had lived in Bogota, Colombia for at least one year. Subjects with hormone replacement therapy or high blood pressure during this test, coronary artery or valvular heart disease or conduction disorders, were excluded. Physical activity was determined applying the Ainsworthy et al. survey, body composition by bioelectrical impedance analysis and VO2max by ergospirometry. Results: sample size was 21 participants. Half of the population showed a VO2max of 23.7 ml/k/min, BMI of 27.2g/m2 and muscle mass of 35.5%. A low correlation between VO2max and muscle mass was evidenced. Half of the healthy population had a VO2max of 28.9 ml/k/min, healthy sedentary subjects 23.7 ml/k/min and sedentary subjects with risk factors 21.6 ml/k/min. Conclusions: this study showed a low correlation between muscle mass and VO2max. However, these results could have been influenced by the sample size and other factors.
