RESUMEN

Objective To understand the body characteristics of adults from the Tibeto-Burman language group. Methods Totally 14 837 adults (6578 males and 8259 females) from 17 minorities were selected for investigation during 2015 to 2019 and these surveys were carried out in regions including Sichuan, Yunnan, Guizhou, Hubei, Hunan and Tibet Autonomous Region. Eight physical parameters (stature, sitting height, etc.) along with 4 corresponding indexes (stature-sitting index and the like) were carefully analyzed. The body characteristics of the Tibeto-Burman language group were then compared to those of certain minorities as well as Han in both northern and southern part of China based on our collected data. Results Among 17 minorities of the Tibeto-Burman language group, people from Pumi and Tibet were relatively tall and have longer trunk and limbs. The presence of wider trunk and thicker limbs appeared to be common in Tibetan individuals. Subjects from Lahu, Jino and Derung were in possession of shorter stature and limbs while the trunk of Naxi, Lisu and Achang people seemed wider. Compared with other ethnic groups in China, individuals from the Tibeto-Burman language group tended to own shorter stature accompanied by medium trunk width, probably sharing similar physical characteristics with those minorities in southern China, especially She and Li. Conclusion Among ethnic groups dotting in southern China, individuals from the Tibeto-Burman language group generally have medium stature, medium trunk height, and wide trunk whereas those from 3 Mon-Khmer groups, Va, Khmus and Blang, are shorter and smaller in width and height of the trunk.

RESUMEN

The purpose of this study was to validate a bioelectrical impedance analysis (BIA) equation for prediction of body fat mass (FM) against dual energy Xray absorptiometry (DXA) in healthy Indian adults with large variations in body mass index and age. Healthy subjects (28 males and 85 females) were investigated by two methods: FM was measured by a dual energy Xray absorptiometry and segmental bioelectrical parameters at various frequencies were measured by a commercial segmental multifrequency BIA instrument. Total body parameters were derived from segmental bioelectrical parameters. As correlation was high and prediction error was low, a single equation was developed for FM as follows: FM = 15.45 + [0.0074 × (Rbody250)] - (3.89 × sex); men = 1, women = 0) + (0.844 × w) - [6938 × (h2/Zbody50)] - (22.22 × h) + [3 × (Xbody250 - Xbody5)/age)] + [1.53 × (Φbody5)] - [0.126 × (Xbody50/h)]. Fat mass predicted with dual energy Xray absorptiometry was 28.11 ± 9.30 kg. BIApredicted FM was 28.12 ± 9.11 kg (R = 0.9794, adjusted R2 = 0.9561, standard error of estimate = 1.95 kg, total error = 1.87 kg). In conclusion, the new developed BIA equation was valid for prediction of FM in healthy subjects aged 23 to 81 years with body mass indices between 15.62 and 39.98 kg.m-2. Inclusion of reactance in the kg.m-2 single prediction equation appeared to be essential for use of BIA equation in adults with large variations in body mass and age.

RESUMEN

There is disagreement as to whether there is a correlation between esophageal body length and that of various measurable external body parameters. This length has also been noted to vary in various disease states of the upper gastrointestinal tract and among various races. To our knowledge no such study has been published amongst an African population and Kenyans in particular. The purpose of this study was to determine how the length of the esophagus correlates with various external body parameters. This was a cross-sectional observational study at the endoscopy unit of Kenyatta National Hospital (KNH). All consenting patients undergoing upper gastrointestinal endoscopy (OGD) at KNH. 76 subjects undergoing flexible esophagoscopy were evaluated. 43 were male. The mean esophageal length was 22.2 cm (SD 2.63). Males had a longer esophagus than women. The esophageal length had a negative correlation with weight of individual and body mass index. There was a positive correlation between esophageal length versus height of the individual and the sternal length. Individual's height is the parameter that best correlates with the esophageal body length.


Hay desacuerdo en cuanto a si existe una correlación entre la longitud del cuerpo esofágico y la de varios parámetros corporales externos medibles. Esta longitud se ha observado que varía en diferentes estados de enfermedades del tracto gastrointestinal superior y entre distintas razas. Según la literatura consultada, ningún estudio de este tipo se ha publicado, en particular, entre una población de África y Kenia. El propósito de este estudio fue determinar cómo la longitud del esófago se correlaciona con diversos parámetros corporales externos. Se realizó un estudio observacional y transversal en la Unidad de Endoscopía del Hospital Nacional Kenyatta (KNH). Todos los pacientes sometidos consintieron a la la endoscopía digestiva alta (OGD) en KNH. Fueron evaluados76 pacientes sometidos a endoscopía flexible. (43 eran hombres). La longitud promedio del esófago fue de 22,2 cm (DE 2,63). Los hombres tuvieron un esófago más largo que las mujeres. La longitud del esófago tuvo una correlación negativa con el peso del individuo y su índice de masa corporal. Hubo una correlación positiva entre la longitud del esófago en comparación con la altura de la persona y la longitud esternal. La altura individual es el parámetro que mejor se correlaciona con la longitud del cuerpo esofágico.
