目的建立中国新疆地区哈萨克族7~18岁中小学生超重和肥胖的体重指数(BMI)百分位曲线和界值点参考标准。方法采用横断面调查研究,在中国新疆阿勒泰市及其所属乡镇的中小学采用整群随机抽样方法抽取4所学校(共49个班级)同意参加调查的哈萨克族7~18岁中小学生为调查对象。采集性别、年龄、身高和体重测量资料;应用偏度-中位数-变异系数法建立哈萨克族7~18岁中小学生的BMI百分位曲线;利用儿童青少年超重和肥胖的BMI百分位数曲线在18岁通过国际肥胖工作小组(IOTF)定义的成人超重和肥胖BMI界值点(25kg·m^-2/30kg·m^-2)和中国肥胖问题工作组(WGOC)定义的界值点(24kg·m^-2和28kg·m^-2)的方法,计算出哈萨克族7~18岁各年龄超重和肥胖的BMI界值点。结果共采集7~18岁中小学生2487名,其中男1158名,女1329名。①按照IOTF标准,超重和肥胖的BMI百分位曲线:男性分别为P88.63和P98.28,女性分别为P84.41和P98.12;按照WGOC标准,超重和肥胖的BMI百分位数曲线:男性分别为P92.96和P99.28,女性分别为P90.53和P99.38。②哈萨克族男性超重和肥胖BMI标准曲线低于WGOC和IOTF标准;女性肥胖标准曲线13~14岁前低于WGOC和IOTF标准,之后略高于WGOC和IOTF标准。③哈萨克族男性超重、肥胖的界值百分位曲线均低于或接近的汉族和维吾尔族水平;哈萨克族女性超重界值百分位曲线在14岁前介于汉族和维吾尔族间,之后接近或达到汉族水平;肥胖界值百分位曲线在10岁前低于汉族和维吾尔族水平,14岁后达到或接近汉族水平。结论儿童青少年BMI分布有显著的地域差异和民族差异,哈萨克族中小学生超重和肥胖BMI界值标准不同于IOTF和WGOC所建议的相应标准。因此哈萨克族中小学生超重、肥胖人群的筛查可以参考本研究建立的标准。 相似文献

A 6-year-old boy with congenital hip dislocation, developmental delay, short stature, macrocephaly, low set ears, short neck, and hyperlaxity of the wrists and fingers is described. Radiographs disclosed mainly the presence of thoracic scoliosis, narrow interpedicular distances, metaphyseal vertical striations, very small irregular epiphyses, right hip dislocation, luxation of both elbows, and severe delay of ossification of the epiphyses and the carpal bones. These features are very close to the newly described entity: spondyloepimetaphyseal dysplasia and multiple dislocations. This patient brings to light the differential diagnosis and confirms the specificity of the radiological findings of this new entity. 相似文献

Skeletal maturation is divisible to three main components; the time of appearance of an ossification center, its change in morphology and time of fusion to a primary ossification center. With regard to the knee, the intermediate period between appearance and fusion of the ossification centers extends over a period of greater than 10 years. This study aims to investigate radiographically the age at which morphological changes of the epiphyses at the knee occur in a modern Irish population. Radiographs of 221 subjects (137 males; 84 females) aged 9–19 years were examined. Seven nonmetric indicators of maturity were assessed using criteria modified from the Roche, Wainer, and Thissen method and Pyle and Hoerr's atlas of the knee. Reference charts are presented which display the timeline for each of the grades of development of the seven indicators. Mean age was found to increase significantly with successive grades of development of each of the seven indicators. A significant difference was noted between males and females at the same grade of development for six of the seven indicators. The narrowest age range reported for a single grade of development was 2.2 years for Grade 2 of development of the tibial tuberosity for males. The information on changing morphology of the epiphyses at the knee in the present study may provide an adjunct to methods used for evaluation of skeletal maturity before surgery for orthopedic disorders or to evaluate skeletal age in clinical scenarios where either delayed or precocious skeletal maturation is suspected.

Incidence and ossification of sesamoid bones in the hands and feet: a radiographic study in an Arab population 总被引:2,自引:0,他引:2
The incidence and ossification of sesamoid bones in the hands and feet were studied in 922 radiographs (400 hands and 522 feet) in an Arab population from Bahrain, 5-83 years of age and consisting of 549 adults (393 men and 156 women) and 373 children (286 boys and 97 girls). All radiographs of the hand and foot in the adult population showed two sesamoid bones in the thumb metacarpophalangeal (MCP) joint and in the hallucal metatarsophalangeal (MTP) joint, respectively. Only 2.3% and 1.5% of hands showed sesamoids at the MCP joints of the middle and ring fingers respectively compared to a reported incidence of 7.1% for each digit in Caucasians. The incidence of sesamoids in the MTP joints of third and fourth toes (0.6% each) and inferior to the hallucal interphalangeal joint (3.1%) is probably the lowest reported so far in the literature. In the hands, ossification commenced first in the thumb sesamoids, at the age of 10 years in females and 11 years in males and was completed by the age of 13 and 14 years, respectively. In the feet, ossification began first in the hallucal sesamoids at the age of 8 years in females and 9 years in males and was completed by the age of 10 years in both sexes. The incidence and ossification of sesamoids in the hands and feet in the Arab population from Bahrain seem to differ considerably from reports in other populations. The clinical significance of our findings is discussed. 相似文献

股骨下端骺微血管的观察 总被引:1,自引:1,他引:1
本文报道用微血管造影及组织切片的方法,观察了18例胚胎和10例儿童的股骨下端骺。结果发现仅关节软骨内无血管。而软骨骺内的血管分布有一定规律:从髁间窝来的血管分布于骺中心区域;两髁侧面来的血管分布于两髁外侧份;骺软骨板附近的血管主要来自髌面上方及髁间窝上方。骺骨化中心最早围绕软骨管发生。骨化向周围扩展的速度不均匀,靠近血管处比远离血管处扩展块。骺未化骨时,其内的血管处于软骨管内,在化骨过程中,部分转变为骨骺血管,继续供应骺骨化中心: 2岁前,仅由3~5支来自髁间窝的血管供应;2岁后,髌面上方来的血管也开始进入;5岁后,两髁侧面来的血管相继开始供应骺骨化中心。 相似文献

In this report, we describe a brother and sister who presented at birth with short-limb skeletal dysplasia, polyhydramnios, prematurity, and generalized edema. Dysmorphic features included broad nose, thick ears, thin lips, micrognathia, inverted nipples, ulnar deviation at the wrists, spatulate fingers, fifth finger camptodactyly, nail hypoplasia, and talipes equinovarus. Other features included short stature, microcephaly, psychomotor retardation, B-cell lymphopenic hypogammaglobulinemia, sensorineural deafness, retinal detachment and blindness, intestinal malrotation with poor gastrointestinal motility, persistent hyponatremia, intermittent hypoglycemia, and thrombocytopenia. Cardiac anomalies included PDA, VSD, hypertrophic cardiomyopathy, and arrhythmias. The brother had a small penis with hypospadias, hypoplastic scrotum, and non-palpable testes. Skeletal findings included absent ossification of cervical vertebral bodies, pubic bones, knee epiphyses, and tali. Both sibs died before age 2 years, one of overwhelming sepsis and the other of cardiorespiratory failure associated with her cardiomyopathy. Metabolic studies showed a type 1 pattern of abnormal serum transferrin glycosylation. Fibroblasts synthesized truncated LLOs, primarily Man(7)GlcNAc(2), suggestive of CDG-Ig. Both sibs were compound heterozygotes for a novel 301 G > A (G101R) mutation and a previously described 437 G > A (R146Q) mutation in ALG12. Congenital disorders of glycosylation should be considered for children with undiagnosed multi-system disease including neurodevelopmental delay, skeletal dysplasia, immune deficiency, male genital hypoplasia, and cardiomyopathy. 相似文献

We present a case of opsismodysplasia, a very rare skeletal dysplasia, in a term newborn female who had short length, short extremities and markedly short fingers. Radiological studies demonstrated severe platyspondyly, absence of epiphyseal ossification centers, short tubular bones, especially severe in hands and feet, with metaphyseal cupping. She also had hydrocephaly, a rare finding in opsismodysplasia. In our literature review we have found 24 cases, 17 born alive and seven terminations of pregnancy (TOPs). 相似文献

This paper describes an extensive study of the growth of ossification centers in limb long bones of the human fetus from 8 to 26 weeks of conceptual age. Longitudinal measurements were made of the femur, tibia, fibula, humerus, radius, and ulna. Comparisons were made between bones on the left and right sides of the body and between the sexes. Standards are presented for the growth of these centers. They compare well with previous studies, any differences being accounted for by different methods of aging and measurement. A complicated picture of growth of the two sides of the fetal body is presented. Growth of the humerus, tibia, and fibula appears to be dominant on the left side of the body while growth in the femur is dominant on the right. At present, no explanation is available, but it is possible that factors such as manual dominance may be related. Evidence also is presented which suggests that the female fetus is in advance of the male in terms of ossification but only after 21 weeks gestation. 相似文献

We present 2 unrelated children with a distinct pattern of anomalies, including mental retardation, hearing impairment, unusual facial appearance, and skeletal defects. Both children have severe behavior disturbance and hyperactivity. The characteristic facial findings include a broad mouth, broad nasal bridge, mildly anteverted nares with a fleshy nasal tip, and deep nasolabial folds. Skeletal findings include mild to moderate short stature, dysharmonic maturation of epiphyseal ossification centers in the hands, and mild scoliosis. 相似文献
