ObjectiveTo systematically review the current prevalence, key determinants, and prevention strategies of child and adolescent obesity in China. MethodA systematic review of the epidemiological trends, health impacts, risk factors, and intervention strategies for child and adolescent obesity was performed by analyzing recent domestic and international literature and policy documents, supplemented with national surveillance data and developments in clinical practice. ResultsThe prevalence of child and adolescent obesity in China has been rising continuously over the past four decades, with particularly high rates observed among primary school children and boys. Recent trends show a “provincial reversal” and an “urban-rural reversal”. This high-risk environment stems from complex interactions among family, school, and societal factors. China has developed a relatively comprehensive policy framework for obesity prevention and control and is promoting a three-tiered prevention strategy. Clinically, pharmacological and surgical interventions are being gradually adopted. However, challenges remain, including limited health insurance coverage for obesity management. ConclusionsChild and adolescent obesity has become a significant public health issue in China, threatening national health and social development. Future efforts should focus on enhancing intersectoral governance, improving early intervention capabilities, expanding health insurance support, and standardizing clinical practices. A multi-level, multi-pathway integrated prevention and control system is essential for effectively curbing child and adolescent obesity under the healthy China strategy.
Foot shape and size are important for footwear design and production. Information about important foot characteristics helps not only to improve shoe comfort but to maintain the proper physiological development of the feet. What’s more, plenty of studies have suggested that the shape of the shoe must closely resemble the shape of the foot to create a properly fitted shoe. This means that the differences between various populations should be considered and that footwear should be designed according to the measurements of users. Childhood and adolescent are important periods of human growth. During these periods, foot shape changes with human growth and can be influenced by extrinsic factors. Therefore, the foot shape characteristics of children and adolescents should be investigated. The results from these investigations can contribute to developing appropriate shoe for children and adolescents, improving perceived comfort of children shoes and preventing pedopathy among children and adolescents. This review aims to discuss measuring methods of foot shape, types of foot shape, and factors influencing foot shape. The results of the review can provide recommendations for investigating growth development of foot shape and useful information for consumers and shoe manufacturers.
Objective To explore the feasibility and early effectiveness of computer-simulated osteotomy based on the health-side combined with guide plate technique in the treatment of cubitus varus deformity in adolescents. Methods The clinical data of 23 patients with cubitus varus deformity who met the selection criteria between June 2019 and February 2023 were retrospectively analyzed. There were 17 males and 6 females, ranging in age from 4 to 16 years with an average of 8.5 years. The time from injury to operation was 1-4 years. The angle of distal humerus rotation was defined by humeral head posterior inclination angle using low radiation dose CT to scan the patient’s upper extremity data at one time, and the preoperative rotation of the distal humerus on the affected side was (33.82±4.39)°. The CT plain scan data were imported into 9yuan3D digital orthopaedic system (V3.34 software) to reconstruct three-dimensional images of both upper extremities. The simulated operation was performed with the healthy upper extremity as the reference, the best osteotomy scheme was planned, overlapped and compared, and the osteotomy guide plate was prepared. The patients were followed up regularly after operation, and the formation of callus in the osteotomy area was observed by X-ray examination. Before and after operation, the carrying angle of both upper extremities (the angle of cubitus valgus was positive, and the angle of cubitus varus was negative) and anteversion angle were measured on X-ray and CT images. At the same time, the flexion and extension range of motion of elbow joint and the external rotation range of motion of upper extremity were measured, and Mayo score was used to evaluate the function of elbow joint. ResultsThe operation time ranged from 34 to 46 minutes, with an average of 39 minutes. All patients were followed up 5-26 months, with a mean of 14.9 months. All the incisions healed by first intention after the operation; 2 patients had nail path irritation symptoms after Kirschner wire fixation, which improved after dressing change; no complication such as breakage and loosening of internal fixators occurred after regular X-ray review. Continuous callus formed at the osteotomy end at 4 weeks after operation, and the osteotomy end healed at 8-12 weeks after operation. At last follow-up, the carrying angle, anteversion angle, external rotation range of motion, and extension and flexion range of motion of the elbow joint of the affected side significantly improved when compared with preoperative ones (P<0.05). Except for the extension range of motion of the healthy elbow joint (P<0.05), there was no significant difference in other indicators between the two sides (P>0.05). At last follow-up, the Mayo elbow score was 85-100, with an average of 99.3; 22 cases were excellent, 1 case was good, and the excellent and good rate was 100%. ConclusionComputer-simulated osteotomy based on health-side combined with guide plate technique for treating cubitus varus deformity in adolescents can achieve precise osteotomy, which has the advantages of short operation time and easy operation, and the short-term effectiveness is satisfactory.
ObjectiveTo evaluate the effectiveness of modified Ilizarov hip reconstruction in the treatment of hip instability.MethodsThe clinical data of 13 young patients with hip diseases treated with modified Ilizarov hip reconstruction between January 2010 and March 2018 were retrospectively analyzed. There were 2 males and 11 females, aged from 14 to 34 years, with an average age of 24.2 years. There were 1 case of hip dysplasia and dislocation due to spinal bifida, 3 cases of hip dysplasia after pyogenic arthritis of the hip, 2 cases of developmental dysplasiaof the hip (DDH) accompanying femoral head necrosis who rejected hip replacement, 6 cases of young DDH refused to undergo hip replacement, and 1 case of bilateral hip dysplasia with dislocation due to sputum cerebral palsy. The disease duration was 2-20 years, with an average of 8.5 years. Preoperative Trendelenburg sign was positive in 12 cases and negative in 1 case. The preoperative Harris score of hip joint was 53.5±8.9 and the unequal length of lower limbs was (46.08±15.73) mm. Postoperative Harris hip score and patients' satisfaction with effectiveness evaluated according to their self scoring were used to assess the effectiveness.ResultsAll 13 patients were followed up 1-5 years, with an average of 2.6 years. Five patients developed postoperative needle infection, which improved after dressing change; 7 patients had limited knee joint activity and improved after knee joint function training. The Trendelenburg sign was negative at 1 year after operation, and the patient’s hip pain symptoms were relieved or disappeared. The Harris hip score of patients at 1 year after operation was 84.5±6.1, which was significantly improved when compared with preoperative one (t=－10.538, P=0.000). According to Harris hip score, the effectiveness results were excellent in 4 cases, good in 5 cases, and fair in 4 cases, with an excellent and good rate of 69.2%. The unequal length of lower limbs was (15.38±7.27) mm, which was significantly better than that before operation (t=11.826, P=0.000). At last follow-up, the patients' satisfaction score was 80%-95%, with an average of 88%.ConclusionModified Ilizarov hip reconstruction can be used to treat young patients with hip disease who are unsuitable or refuse to undergo artificial hip replacement. Its effectiveness is reliable, and it has unique advantages in limb limp improvement and limb shortening correction.

Objective
To explore effectiveness of suture-bridge fixation under arthroscopy in treatment of tibial eminence avulsion fracture of anterior cruciate ligament in adolescents.
Methods
Between June 2013 and October 2016, 18 adolescent patients suffered from tibial eminence avulsion fracture of anterior cruciate ligament were treated by suture-bridge fixation under arthroscopy. There were 11 males and 7 females with an average age of 12.5 years (range, 5-17 years). The injury caused by bruise in 6 cases, by sprain in 4 cases, and by sport injury in 8 cases. The interval between injury and admission ranged from 2 hours to 10 months (median, 2 months). The results of preoperative Lachman and anterior drawer tests were positive. There were 10 cases of knee pain, 4 cases of knee extension limitation, and 4 cases of knee extension without strength. According to the Meyer-McKeever classification criteria, 12 cases were type Ⅱ and 6 cases were type Ⅲ.
Results
All incisions healed by first intention. All 18 patients were followed up 10-18 months after operation, with an average of 12 months. Postoperative X-ray films showed that all fractures healed after 6-12 weeks (mean, 8 weeks). The results of postoperative Lachman and anterior drawer tests were negative. At last follow-up, the Lysholm knee score was 90.1±5.0 and 93.1±6.2 for affected and unaffected sides, respectively, showing no signifi cant difference (t=0.669, P=0.184). There was no premature closure of skeleton or leg length discrepancy deformity.
Conclusion
For tibial eminence avulsion fracture of anterior cruciate ligament in adolescents, the suture-bridge fixation under arthroscopy is an effective method with many advantages, such as minimal invasion, reliable fixation, good fracture healing, and no need for second operation to remove implants.
Objective
To explore the effectiveness of rigid interlocking nails through the tip of the greater trochanter for fixation of femur shaft fracture in adolescent.
Methods
A retrospective analysis was made on the clinical data of 23 adolescents with femoral shaft fractures treated between June 2011 and June 2015. Of 23 cases, 19 were male and 4 were female, aged from 13 years and 6 months to 17 years (mean, 15.2 years), weighed from 40 to 77 kg (mean, 53.5 kg). The causes were traffic accident injury in 13 cases, sports injury in 7 cases, and falling injury in 3 cases. Fracture located at the proximal 1/3 in 6 cases, middle 1/3 in 10 cases, and distal 1/3 in 7 cases; fracture was typed as transverse in 10 cases, oblique in 6 cases, spiral in 1 case, and comminuted in 6 cases. The course of disease was 3-17 days (mean, 6.2 days). At last follow-up, the leg length discrepancy, femoral neck shaft angle, femoral neck diameter, and articulotrochanteric distance (ATD) were measured on the X-ray films.
Results
Wounds healed in all patients, and no infection occurred. All patients were followed up 15-36 months (mean, 26.5 months). The patients had no pain and had normal gait, without lameness. The X-ray films showed bone healing at 5-13 months (mean, 6.5 months). No nonunion, delayed union, malunion of more than 5 °, or rotational deformity occurred. The removal time of internal fixations was 12-24 months (mean, 19.5 months) after operation. No heterotopic ossification, re-fracture, proximal femoral deformity, or femoral head necrosis occurred during follow-up. Two patients had early epiphyseal closure of greater trochanter, which had no impact on gait; leg-length inequality of less than 1 cm was observed in 2 cases. At last follow-up, the neck shaft angle, femoral neck diameter, and ATD of normal and affected sides were (131.7±6.3) and (132.9±7.8)°, (34.1±3.2) and (33.9±3.8) mm, and (27.8±9.2) and (26.5±8.5) mm, showing no significant difference between two sides (t=–0.24,P=0.86;t=0.18,P=0.92;t=1.03,P=0.49).
Conclusion
It is a reliable and effective method to use rigid interlocking nails inserted through the tip of the greater trochanter for the fixation of femur shaft fracture in adolescent.
ObjectiveTo review the advances in perioperative pain management of pediatric and adolescent spinal deformity corrective surgery.MethodsRegular analgesics, drug administrations, and analgesic regimens were reviewed and summarized by consulting domestic and overseas related literatures about perioperative pain management of pediatric and adolescent spinal deformity corrective surgery in recent years.ResultsAs for perioperative analgesis regimens of pediatric and adolescent spinal deformity corrective surgery, regular analgesics include non-steroidal anti-inflammatory drugs, opioids, antiepileptic drugs, adrenergic agonists, and local anesthetic, etc. Besides drug administration by mouth, intravenous injection, and intramuscular injection, the administration also includes patient controlled analgesia, epidural injection, and intrathecal injection. Multimodal analgesia is the most important regimen currently.ConclusionHeretofore, a number of perioperative pain managements of pediatric and adolescent spinal deformity corrective surgery have been applied clinically, but the ideal regimen has not been developed. To design a safe and effective analgesic regimen needs further investigations.
ObjectiveTo compare the effects of aerobic exercise, resistance exercise, aerobic combined with resistance exercise, routine nursing and no intervention on depression and anxiety in adolescents by means of network meta-analysis. MethodsA computer search was conducted in CNKI, WanFang Data, VIP, CBM, Web of Science, EBSCO, PubMed, Cochrane Library and Embase to collect randomized controlled trials (RCTs) related to exercise intervention for depression and anxiety in children and adolescents from inception to April 2023. After two researchers independently screened the literature, extracted data and evaluated the methodological quality of the included studies, Stata 14.0 and RevMan 5.3 software were used for statistical analysis. ResultsFinally 27 RCTs were included, covering 3 210 children and adolescents. The results of the network meta-analysis showed that in terms of improving depression, resistance exercise (SMD=?0.37, 95%CI ?0.64 to ?0.10, P<0.05) and aerobic exercise (SMD=?0.19, 95%CI ?0.34 to ?0.04, P<0.01) were significantly better than the no intervention group; in relieving anxiety, aerobic exercise (SMD=?0.29, 95%CI ?0.54 to ?0.03, P<0.05) was significantly better than the no intervention group. In improving self-worth, aerobic combined with resistance exercise (SMD=0.26, 95%CI 0.01 to 0.52, P<0.05) was statistically different from the no intervention group. The results of SUCRA probability sequence showed that in reducing depression, resistance exercise (95.0%) > aerobic exercise (64.4%) > aerobic combined with resistance exercise (60.7%) > routine nursing (22.9%) > no intervention (7.0%). In relieving anxiety, aerobic exercise (72.4%) > routine nursing (69.0%) > aerobic combined with resistance exercise (55.3%) > no intervention (3.4%). In improving self-worth, aerobic combined with resistance exercise (94.0%) > resistance exercise (67.3%) > aerobic exercise (35.1%) > no intervention (32.7%) > routine nursing (21.0%). ConclusionLimited evidence suggests that resistance exercise has advantages in improving depression in children and adolescents, aerobic exercise has advantages in relieving anxiety in children and adolescents, and aerobic combined with resistance exercise has advantages in improving self-worth in children and adolescents. Due to the limitation of the number and quality of included studies, more high-quality studies are needed to verify the above conclusions.
Objective
To investigate the prevalence and related factors of primary palmar hyperhidrosis in adolescents in Yangzhou.
Methods
On-site questionnaire survey was performed on students selected by cluster random sampling from the two colleges and two high or middle schools, with each class as a unit. Data were collected through the questionnaire to make the diagnosis and severity grading.
Results
A total of 3 487 copies of the questionnaire were distributed in the survey and 3 299 were finished, among which 3 083 were effective with an effective rate of 88.41%. Among them, 1 358 respondents were males and 1 725 were females; 933 were middle school students, 809 high school students, and the remaining 1 341 college students. According to the diagnostic criteria, 104 respondents were diagnosed with palmar hyperhidrosis with an overall prevalence of 3.37%. There were 60 (4.41%) males and 44 (2.55%) females. Although the prevalence of palmar hyperhidrosis in males was higher than that of females (χ2=8.130, P<0.05), severe palmar hyperhidrosis was more often to be observed in females than in males, and females were also more likely to have hyperhidrosis in other parts of the body. In addition, the age of the first onset of the disease was mainly 10 to 20 years old and 36.54% of the patients had a family history.
Conclusion
The prevalence of palmar hyperhidrosis in adolescents in Yangzhou was 3.37%, and there is a significant difference in the gender. The palmar hyperhidros is often accompanied by hyperhidrosis symptoms of other parts of body, and the disease shows an obvious genetic predisposition.
