ABSTRACT
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.
ABSTRACT
This study was performed to identify nutritional status and eating behaviors of underweight male adolescents aged 15 to 19 years. The subjects selected by using the data of KNHANS-2001 were 32 underweight boys and 135 normalweight ones. We found that weight, waist and hip circumference of the underweight group were significantly different to normal-weight group, but height and waist-hip ratio were not. Their serum indices belonged within normal ranges and showed no difference between the two groups. Their energy and nutrient intakes were mostly poor. The level and proportion of the subjects below EAR, NAR and INQ of each nutrient were not significantly different between the two groups. There were no difference of frequencies of skipping meals, snacking and eating-out between the two groups, either. When comparing frequencies of food intakes, the underweight group consumed significantly more of fermented fishes and less milk than the normal-weight group. And the former had significantly more rest/sleep, nodoes and supplementation and less regular excercise than the latter. The underweight group perceived more correct self-images than the normal-weight group and they tried more to increase their body weight during weight control practice (p < 0.001). It was concluded that the underweight group showed no different biochemical indices, nutrient intakes, and dietary behaviors to the normal-weight group, but they revealed significantly higher non-active activities like rest and supplementations.

BACKGROUND: This study was performed to evaluate the correlations between lumbar epidural depth by MRI and physical measurements. METHODS: The anatomy of the lumbar epidural space was evaluated using MRI scans of 121 patients (93 male and 31 female). Epidural depth was measured from the skin to the center of the posterior epidural space at the L3-4 and L 4-5 levels by two methods (in a parallel line to the lumbar spinous process [SKEP I] and in a vertical line to the long axis of the spine [SKEP II]). Physical measurements such as weight, height, foot size, and waist were measured, other physical measurements such as the Ponderal index (PI), body mass index (BMI), and obesity (Broca's index) were calculated. RESULTS: Significant correlations between depth from the skin to the posterior epidural space were found for Ponderal index (PI), body mass index (BMI), obesity (Broca's index), weight, waist circumference, height, and foot size. The depth from the skin to the supraspinous ligament correlated with BMI, obesity (Broca's index), PI, weight, and waist circumference. The depth from the supraspinous ligament to the posterior epidural space were found to correlate with height and foot size. CONCLUSIONS: PI had a higher predictive value for epidural depth than the other physical measurements.
