Objective: The status of masked obesity in female college students and the related factors were investigated to provide a theoretical reference for instructing the physical health education of female college students and improving their physical exercises. Methods: Body composition tests were performed on 2 975 female college students, selected from 3 colleges in North China by using cluster sampling method during October to December in 2018, and their basic information and lifestyle were investigated using questionnaires. Results: The incidence of masked obesity among female college students was 33.18%, of which 2.53% came from low-weight people. The difference in the incidence of masked obesity among female college students with different take-out frequencies was statistically significant (χ2=21.98, P<0.01). Compared with those who never take takeaway, people who take takeaway every day have an increased risk of masked obesity (OR=1.49, 95%CI=0.76-2.91). The difference in the incidence of masked obesity with the frequency of eating midnight snack was statistically significant (χ2=20.80, P<0.05). The difference in the incidence of masked obesity among female college students with different exercise time was statistically significant (χ2=18.49, P<0.01). Compared with exercise time above 60 min/d, female college students who are not exercising have an increased risk of masked obesity (OR=3.20, 95%CI=1.63-6.30). The difference in the incidence of masked obesity among female college students with different weight satisfaction was statistically significant (χ2=217.54, P<0.01). Compared with female college students who were satisfied with weight, female college students who were not satisfied with weight had an increased risk of masked obesity (OR=3.47, 95%CI=1.91-6.31). The difference in the incidence of masked obesity in different weightdown plans is statistically significant (χ2=186.40, P<0.01). Those who want to lose weight have a higher risk of developing masked obesity than those who want to gain weight (OR=18.11, 95%CI=5.54-50.13). Conclusion Female college students who drink a small amount of water, eat takeaways often, eat midnight snacks, do not exercise, and are not satisfied with their weight are more likely to develop masked obesity.

Objective:To quantify any correlation between the severity of spinal curvature of an adolescent with idiopathic scoliosis and their cardiopulmonary exercise endurance.Methods:The cardiopulmonary exercise test (CPET) results and the full-length spinal X-rays in a standing position of 64 adolescents with idiopathic scoliosis were reviewed retrospectively. Independent t-tests were used to compare the two datasets obtained from those with left or right thoracic scoliosis. The correlation between the Cobb angle and cardiopulmonary exercise endurance was analyzed using Pearson correlation coefficients, multiple factor linear regression and two-stage linear regression.Results:After adjusting for gender, age, height and weight, the multiple linear regression analysis showed that the Cobb angle was significantly negatively correlated with maximum tidal volume (β=-0.013) and significantly positively correlated with the rate of respiration (β=0.421). The relationship between the Cobb angle and cardiopulmonary exercise endurance was non-linear. With a Cobb angle > 34°, a 1° increase reduces cardiopulmonary exercise endurance by a factor of 1.4 on average. At smaller Cobb angles the corresponding increase is about 0.87 times.Conclusions:The Cobb angle is a negative predictor of ventilation during exercise among adolescents with idiopathic scoliosis. The more severe a patient′s spinal curvature, the lower the cardiopulmonary exercise endurance is likely to be.

ObjectiveTo observe the effects of specific exercise therapy on spinal deformity and joint hypermobility of idiopathic scoliosis. MethodsFrom April to October, 2021, 100 children with idiopathic scoliosis in the Scoliosis Rehabilitation Center of Xinhua Hospital were divided into control group (n = 50) and experimental group (n = 50), who accepted routine exercise therapy or scoliosis-specific exercise therapy in accordance with their wishes, for six months. The maximum Cobb angle and bone mineral density were measured, and they were assessed with Beighton Scale and Chinese version of the Scoliosis Research Society-22 Questionnaire Scores (SRS-22) before and after treatment. ResultsThe change of the maximum Cobb angle was more in the experimental group than in the control group (Z = -2.202, P < 0.05) after treatment, and the incidence of respondent was more (χ² = -2.405, P < 0.05). The bone mineral density decreased in the experimental group after treatment (|Z| > 2.127, P < 0.05). For SRS-22, the total scores increased in both groups after treatment (F_time = 106.57, P < 0.001), and increased more in the experimental group than in the control group (F = 4.969, P < 0.05); the scores of function domain and self-image domain increased in the experimental group (|Z| > 2.149, P < 0.05), while the mental health domain score decreased in the control group (Z = -2.096, P < 0.05); and the mental health domain score was more in the experimental group than in the control group (Z = -2.260, P < 0.05). ConclusionThe scoliosis-specific exercise therapy is effective on spinal deformity and quality of life for children with idiopathic scoliosis, but less helpful for joint hypermobility and bone mineral density, which need to further improve.
