Alteraciones somatométricas y menor puntaje aPGar en recién nacidos indígenas / Somatometric alterations and lower APGAR score in indigenous newborns

Introducción: la población indígena es vulnerable y poco se conoce sobre sus indicadores somatométricos y APGAR al nacimiento. Objetivo: explorar la asociación de la condición de recién nacido indígena (RNI) sobre parámetros somatométricos y APGAR al nacimiento. Métodos: estudio transversal exploratorio que empleó el registro de recién nacidos (RN) de una clínica privada. La condición de RNI se determinó por la condición indígena materna. Se consideraron la puntuación APGAR al primer minuto y los indicadores nutricionales derivados del peso, la talla y los perímetros. El análisis estadístico empleó regresiones logísticas. Resultados: el análisis exploratorio involucró a 7413 RN (1,8 % de RNI). El 52 % de los RN eran de sexo masculino y el 8,1 % fueron pretérmino (< 37 semanas). Los RNI, respecto a los RN no indígenas, presentaron mayor riesgo de desnutrición (8 % vs. 6,3 %; p < 0,001), mayor exceso de peso (7,3 % vs. 1,8 %; p < 0,001), menor perímetro cefálico (33,6 cm vs. 34,1 cm; p = 0,017), menor perímetro abdominal (30,9 cm vs. 31,5 cm; p = 0,011) y bajo puntaje APGAR < 7 (8,7 % vs. 1,2 %). La condición de indígena se asoció de manera independiente con el bajo peso (< 2500 g) al nacimiento (OR: 0,4; IC 95 %: 0,2; 0,9), perímetro cefálico en exceso (OR: 2,7; IC 95 %: 1,5; 4,7) y puntaje de APGAR < 7 puntos (OR: 8,3; IC 95 %: 4,2; 16,5). Conclusiones: la condición de indígena se asocia con indicadores que impactan negativamente en la salud de los recién nacidos, como son el perímetro cefálico y el bajo desempeño en la escala APGAR. Estos resultados deben tomarse como un llamado para mejorar la atención prenatal de la población indígena.(AU)

Introduction: the indigenous population is vulnerable and there is limited understanding of their somatometric indicators and APGAR score at birth. Aim: the objective of the study was to explore the association of the condition of indigenous newborn (INB) on somatometric parameters and APGAR score at birth. Methods: this study employed an exploratory cross-sectional design, utilizing the registry of newborns (NB) from a private clinic. The APGAR score at one minute after birth, as well as nutritional indicators derived from measurements of weight, height, and perimeters, were taken into consideration. The statistical analysis involved the use of logistic regressions. Results: the analysis included 7413 NB (1.8 % INB), 52 % were male and 8.1 % were born preterm (gestational age < 37 weeks). In comparison to non-indigenous NB, the INB group showed a higher risk of malnutrition (8 % vs. 6.3 %; p < 0.001), a greater prevalence of excess weight (7.3 % vs. 1.8 %; p < 0.001), smaller head circumference (33.6 cm vs. 34.1 cm; p = 0.017), smaller abdominal circumference (30.9 cm vs. 31.5 cm; p = 0.011), and a higher occurrence of low APGAR scores (< 7) (8.7 % vs. 1.2 %; p < 0.001). Furthermore, the indigenous condition was independently associated with low birth weight (< 2.500 g) (OR, 0.4; 95 % CI, 0.2; 0.9), excess head circumference (OR, 2.7; 95 % CI, 1.5; 4.7), and APGAR score < 7 points (OR, 8.3; 95 % CI, 4.2; 16.5). Conclusions: the indigenous condition was associated with factors that have adverse effects on the health of NB, including reduced head circumference and suboptimal performance on the APGAR scale. These results emphasize the importance of improving access to and quality of prenatal healthcare services for indigenous communities.(AU)

Objective To explore the relationship hetween obesity indexes and body fat rate in Naxi a d u l t s. Methods A total of 687 Naxi adults aged between 18 and 90 were selected from Yulong County, Lijiang City, Yunnan Province. Body weight, height, chest circumference, waist circumference, hip circumference, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, anterior superior spine skinfold, body mass index (BMI), visceral fat index and body fat percentage were measured by anthropometry and bioelectrical impedance analysis. And the indexes and body fat percentage were statistically analyzed. Results The average body fat percentage of Naxi men was normal, while the women was obese. According to the criteria of visceral fat index, the average visceral fat index of Naxi men and women was within the normal range. According to the waist circumference, the waist circumference of Naxi men was within the normal range, while the waist circumference of women belonged to abdominal obesity. Correlation analysis showed that body weight, chest circumference, waist circumference, hip circumference, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, anterior superior iliac spine skinfold, BMI, visceral fat index were positively correlated with body fat percentage among Naxi adults. There was the strongest correlation between visceral fat index and body fat percentage in Naxi men, followed by BMI; Naxi women' s chest circumference and body fat percentage, followed by waist circumference. Conclusion All the obesity indexes of Naxi adults are positively correlated with body fat percentage, and there are gender, regional and ethnic differences in the degree of correlation.

Correlation analysis showed that the three indicators of WHtR, BMI and AVI were positively related to VFL (P< 0 . 0 1) . The ROC showed that the WHtR had the highest value for predicting central obesity in Naxi and Pumi men (P<0. 01), BMI had the highest value of predicting central obesity in Naxi and Pumi women (P<0. 0 1) . Cluster analysis showed that Naxi and Pumi males were similar to southern ethnic groups such as Lisu and Sui, Naxi females were similar to Zang and Jingpo, and Pumi females were similar to southern ethnic groups such as Lisu and Sui. Conclusion WHtR, BMI, AVI to determine central obesity are statistically significant, can be combined with BMI and AVI to determine Naxi, Pumi central obesity.

Validación de los datos antropométricos declarados por padres de participantes en el proyecto SENDO / Validation of the anthropometric data reported by parents of participants in the SENDO project

Objetivo: analizar la validez de las medidas antropométricas declaradas por los padres de los participantes en el proyecto SENDO. Método: el proyecto SENDO (SEguimiento del Niño para un Desarrollo Óptimo) es una cohorte pediátrica abierta y prospectiva. Los participantes se reclutan cuando tienen entre 4 y 6 años, y se siguen anualmente mediante un cuestionario “online”. En una submuestra de 82 participantes, se comparó la información antropométrica declarada en el cuestionario basal con las mediciones directas recogidas por el personal investigador. Para ello, se calcularon el índice de correlación intraclase (ICC) y el coeficiente de mala clasificación de Bland-Altman. Resultados: el ICC fue de 0,96 (intervalo de confianza [IC] del 95 %: 0,94-0,98) para el peso; de 0,95 (IC 95 %: 0,92-0,96) para la altura; de 0,75 (IC 95 %: 0,64-0,86) para el perímetro de la cintura, y de 0,84 (IC 95 %: 0,76-0,89) para el perímetro de la cadera. En relación a los índices calculados a partir de esas mediciones, se encontró un ICC de 0,84 (IC 95 %: 0,77-0,90) para el índice de masa corporal; de 0,46 (IC 95 %: 0,27-0,62) para el cociente cintura-cadera, y de 0,59 (IC 95 %: 0,43-0,72) para el índice cintura-altura. El índice de mala clasificación de Bland-Altman osciló entre el 3,7 % para el peso y el 8,5 % para el índice de masa corporal. Conclusiones: se encontró una muy elevada concordancia para la información antropométrica declarada por los padres y la medida de forma directa. Los resultados indican que las medidas antropométricas referidas por los padres, especialmente aquellas con los que están más familiarizados, son válidas y pueden utilizarse en la investigación epidemiológica.

Objective: to analyze the validity of self-reported somatometry data through a self-reported online questionnaire. Method: the SENDO project (Follow-up of Children for Optimal Development) is a prospective, dynamic pediatric cohort. Participants are recruited when they are between 4 and 6 years old, and followed annually through an online questionnaire. In a subsample of 82 participants, we compared the anthropometric information reported in the baseline questionnaire with the direct measurements collected by the investigating staff. To do this, we calculated the intraclass correlation index (ICC) and the Bland-Altman coefficient. Results: the ICC was 0.96 (95 % confidence interval [CI]: 0.94-0.98 for weight; 0.95 (95 % CI: 0.92-0.96) for height; 0.75 (95 % CI: 0.64-0.86) for waist circumference; and 0.84 (95 % CI: 0.76-0.89) for hip circumference. In relation to the indices calculated from these measurements, we found an ICC of 0.84 (95 % CI: 0.77-0.90) for body mass index; 0.46 (95 % CI: 0.27-0.62) for waist-hip ratio; and 0.59 (95 % CI: 0.43-0.72) for waist-height index. The Bland-Altman index ranged from 3.7 % for weight to 8.5 % for body mass index. Conclusions: we found a high correlation and concordance between the data collected in the physical exam and those reported by the parents. Our results indicate that the anthropometric measures provided by parents, especially those with which they are most familiar, are valid and can be used in epidemiological research. (AU)

Effect of age on electrical nerve conduction in the somatosensory pathway and its correlation with somatometry and plasma concentrations of musculoskeletal enzymes in male rhesus monkeys (Macaca mulatta) held in captivity.

BACKGROUND: Somatosensory evoked potentials (SEPs) make it possible to obtain functional data on the activity of somatosensory pathway. OBJECTIVE: To evaluate the ontogeny of electrical nerve conduction in male rhesus monkeys using SEPs in correlation with the development of the musculoskeletal system based on somatometry and musculoskeletal enzymes. METHODS: Somatosensory evoked potentials of the medial and tibial nerves were performed, and somatometric measurements were obtained: total length, arm and forearm length, and thigh and calf length. Analysis of the musculoskeletal enzymes, lactic dehydrogenase, and creatininase was conducted using blood samples in 20 rhesus monkeys divided into 5 groups. RESULTS: Statistical analysis manifested a delay in the appearance of latencies as age increased. Also evident was a strong, direct relation between the lengths and the value of the latencies of the SEP, together with an inverse relation between the musculoskeletal enzymes. CONCLUSIONS: These findings contribute to standardizing this animal model in the neurophysiological sciences.
