ABSTRACT
Objective@#To explore the epidemiological trend of overweight and obesity, elevated blood pressure and their comorbidities in children and adolescents from Inner Mongolia Autonomous Region during 2016-2021, and to analyze its association with lifestyle, so as to provide reference for formulating prevention and control strategies of regional common comorbidities in schools.@*Methods@#A total of 8 908, 8 222, 9 448, 127 068, 100 778, and 138 540 students aged 10-18 years in Inner Mongolia were selected by stratified random cluster sampling in September each year from 2016 to 2021. Physical examination and questionnaire survey were conducted on the included students. The prevalence trends of overweight，obesity, elevated blood pressure and their co-occurrence were analyzed. Logistic regression was used to compare the prevalence of elevated blood pressure in different body mass index (BMI) groups. After excluding individuals without lifestyle information in 2021, Logistic regression analysis was used on 136 374 subjects to analyze the association between overweight，obesity, elevated blood pressure and their co-occurrence and lifestyle factors.@*Results@#During 2016 to 2021, the prevalence of comorbidity of overweight, obesity with elevated blood pressure among students in Inner Mongolia Autonomous Region were 5.04%，5.14%，4.99%，7.51%，7.60% and 9.45%， respectively . The prevalence of overweight and obesity was 26.94%, 28.07%, 29.62%, 34.19%, 36.71% and 37.53%, respectively. The prevalence of elevated blood pressure were 16.05%, 11.54%, 13.12%, 14.85%, 14.12% and 18.40%, respectively. Except for 2016, the risk of elevated blood pressure in overweight and obese people was higher than that in normal BMI group in other years, and there was a positive correlation between overweight and obesity and elevated blood pressure after gender and urban and rural areas ( P < 0.05 ). In 2021, the detection rate of comorbidity of overweight and obesity with elevated blood pressure among children and adolescents in urban areas was higher than that in suburban counties, and the reporting rate of healthy lifestyle was lower than that in suburban counties ( P <0.05).Skipping breakfast ( OR =1.11，95% CI =1.07-1.16) and non daily moderate and high intensity physical activity( OR =1.27，95% CI =1.20-1.34) were positively correlated with the co-occurrence of overweight，obesity and elevated blood pressure among children and adolescents in Inner Mongolia Autonomous Region. Non daily moderate and high intensity physical activity ≥60 min was positively correlated with elevated blood pressure ( OR =1.11，95% CI =1.07-1.16), and insufficient sleep was positively correlated with overweight，obesity ( OR =1.04, 95% CI =1.01-1.06)（ P ＜0.05）.@*Conclusion@#The prevalence of overweight，obesity, elevated blood pressure and their co-occurrence among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Overweight/obesity is an important risk factor for elevated blood pressure, and unhealthy lifestyles are risk factors for co-occurrence of overweight，obesity and elevated blood pressure. Region specific lifestyle interventions are indispensable for the prevention and control of regional common comorbidities. Urban areas may be a key focus for lifestyle interventions.
ABSTRACT
Objective@#To analyze the prevalence of overweight, obesity and depression among students in the Inner Mongolia Autonomous Region in 2019-2022 and explore the relevant factors affecting the co-morbidity of overweight,obesity and depression among students, so as to provide scientific basis for the prevention of co-morbidity.@*Methods@#From September 2019 to 2022, used stratified random cluster sampling, 90 519,71 560,90 079,91 089 students were selected from all 12 leagues in Inner Mongolia Autonomous Region for questionnaire survey and physical examination. The χ 2 test was used for demographic characteristics and univariate analysis, and a binary Logistic regression model was used to explore the association between lifestyle behaviors and co-morbidity.@*Results@#The detection rate of overweight,obesity among students from 2019-2022 was 29.21%,34.38%,35.20%,34.61%, the detection rate of depression was 18.35%，17.53%，16.43%，16.00%, and the co-morbidity detection rate of the two was 5.52%，5.93%，5.76%，5.46%. The number of overweight,obesity and depression co-morbidity students in 2022 was 4 978 students, and the co-morbidity detection rates of the students were significantly different in terms of the school segments and the family structures ( χ 2=103.51, 99.90, P <0.01). Multivariate Logistic regression analysis showed that consuming sugar sweetened beverages or fried food ≥1 time/d, sometimes or never eat breakfast, watching computer or TV ≥2 h/d, and less than 1 h of moderate-to-vigorous physical activity on weekends were positively correlated with the occurrence of the co-morbidity of overweight,obesity and depression, with the value of OR ranging from 1.17 to 1.59 ( P <0.05). Eated fresh fruits or drinking milk and soy milk ≥1 time/d, outdoor activities ≥1 h/d, sleep ≥8 h/d, not smoking and not drinking alcohol were negatively correlated with the occurrence of comorbid overweight,obesity and depression, with the value of OR ranging from 0.47 to 0.92 ( P < 0.05).@*Conclusion@#The occurrence of overweight,obesity and depressive symptoms co-morbidity in students is associated with dietary, exercise and lifestyle behavior. Targeted measures should be taken to maintain students healthy weight and prevent the occurrence of depression from the aspects of diet, exercise and life habits.

ABSTRACT
Objective@#To investigate the prevalence of Internet addiction and depression of students, and to analyze the co-occurrence and trend, so as to provide a theoretical basis for prevention and controlling measures of Internet addiction and depression.@*Methods@#A total of 6 317,7 152,81 808,71 180 and 89 932 students aged 10 to 24 years from 12 leagues (103 banners) in Inner Mongolia Autonomous Region were selected by stratified random cluster sampling in September each year from 2017 to 2021. The Internet Addiction Scale and the Central for Epidemiologic Studies Depression Scale(CES-D) was used to measure Internet addiction and depression. And the annual inspection rate, group difference and annual change trend in students were calculated. Multivariate linear regression and restricted cubic spline analysis were used to estimate the linear and non linear associations between Internet addiction and depression in students.@*Results@#The Internet addiction proportion in students gradually decreased from 4.1% in 2017 to 2.1% in 2020, but increased to 3.9% in 2021. And the depressive symptoms proportion increased from 20.9% in 2017 to 28.0% in 2020 and 27.0% in 2021. The detection rate of Internet addiction and depression comorbidities remained at 1.8% to 2.5 %. The Internet addiction proportion in boys was higher than that in girls( χ 2=42.82， P <0.05). The depressive symptoms prevalence in girls was higher than that in boys( χ 2= 553.90， P <0.05). Taking reversal in prevalence of Internet addiction in urban and rural areas was observed in 2019. The detection rates of depressive symptoms and comorbidity were higher in urban areas than these in suburban counties on the whole, and the difference showed a trend of decreasing or even equalizing year by year. Internet addiction was positively correlated with depressive symptoms score ( B=1.67, 95%CI =1.64-1.71), the proportion of depressive symptoms ( OR=1.39, 95%CI =1.38-1.41) and the proportion of major depressive symptoms ( OR=1.35, 95%CI =1.33-1.36) among students in 2021 ( P <0.05). An N-shaped curve was found in the significant nonlinear associations between internet addiction and depression across sex, region and school stage.@*Conclusion@#Internet addiction and depression in students show significant linear and non-linear associations, which are consistent in different sexes, regions and school stages. Therefore, relevant measures should be made and implemented in each region, especially in suburb areas, so as to prevent the increasingly development of adolescents and children s Internet addiction and depression.

ABSTRACT
Objective@#To analyze physical fitness and health status and gender differences of middle school students among 5 minorities (Mongolian, Hui, Uyghur, Zhuang and Korean), and to provide the theoretical basis for the strategy formulation.@*Methods@#The present data came from 3 waves of Chinese National Survey on Students Constitution and Health (2010, 2014, and 2019). According to National Standards for Students Physical Health (2014 Revision), excellent, and excellent good physical fitness and health status were defined. Cochran Armitage test was used to examine the trends of physical fitness and health status. Chi square test and Logistic regression were used to analyze the difference of physical fitness and health status by sex and survey year.@*Results@#From 2010 to 2019, the excellent physical fitness and health status rate of Mongolian, Hui, Uyghur, Zhuang and Korean students increased from 1.8%, 0.7%, 0.3%, 0.5% and 1.3% to 4.3%, 2.8%, 1.2%, 1.3% and 3.5%, respectively. The excellent good physical fitness and health status rate of Mongolian, Hui, Uyghur and Zhuang students increased from 12.9%, 8.0%, 7.2 % and 8.4% to 24.7%, 20.1%, 12.6% and 19.8%( Z =6.15，6.71，4.12，3.06，5.26；11.88，13.42，6.70，11.08， P <0.05), respectively. In 2019, students aged 13 to 15 years showed higher proportion of excellent/excellent good physical fitness and health status than that of students aged 16 to 18. Boys were more likely to be in excellent/excellent good physical fitness and health status than girls from 2010 to 2019. The sex difference in excellent/excellent good physical fitness and health status narrowed during 2010 and 2019.@*Conclusion@#Physical fitness and health status of minority students improved while sex difference narrowed during last decade, but there is still a long way to reach the goal proposed by China. Targeted intervention should be proposed to promote physical fitness and health status in accordance with the developmental characteristics, especially for girls and students aged 16 to 18 years.

The overall recommended intakes were largely achieved by consumption of cereals, eggs and sugary drinks, with dietary index scores of 9.91(8.24,10.00), 5.58(0,8.58) and 9.20(7.38,10.00), respectively; there were inadequate intakes of vegetables, legumes, water, vitamin A and dietary fiber, with scores of 5.63(4.09,7.59), 3.48 (0,9.70), 4.23(2.67,5.50), 2.33(1.56,3.53), 3.19(1.63,5.67), respectively; intake of fruits, dairy and aquatic products were severely deficient, with scores of 0(0,1.74), 0(0,2.37), 0(0,9.85), respectively; excessive intake of meat was found, with a dietary index score of 0(0,2.46). The stratified analysis showed that children and adolescents aged 11-13 years had the highest total dietary scores[65.35(54.29,72.03)], followed by those aged 7-10 years[63.46(56.19,72.63)], while the 14-17 year old age group had the lowest scores[59.07(51.15,68.30), H=32.23, P <0.01]. Girls had higher total dietary scores than that of boys[64.20(56.12,72.56), 59.32(52.60,69.72), Z=-5.16, P <0.01], while urban children and adolescents had higher total dietary scores than rural children and adolescents[65.30(54.84,73.62), 62.17(54.31,70.70), Z=-2.11, P <0.05]. Furthermore, higher total dietary index scores were observed among children and adolescents whose parents had a higher educational level( H=27.68, 22.58, P <0.01). The comparison of ethnic groups revealed that the Wa children and adolescents had the highest total dietary index scores, while the Hani children had the lowest( H=27.51, P <0.01).@*Conclusion@#The overall dietary quality of children and adolescents in Yunnan Province is not high, the imbalance of dietary nutrition is prominent, and the dietary structure needs to be adjusted and optimized. Intervention programs should focus on the problem of insufficient intake of fruits and vegetables, milk and legumes, aquatic products and excessive intake of poultry meat among children and adolescents.
ABSTRACT
Resumo Nesta entrevista à revista Saúde e Sociedade, a Dra. Cupertino faz um relato do seu engajamento para alcançar pessoas em situações desafiadoras como a pandemia de covid-19. O diálogo buscou conhecer experiências exitosas capazes de interromper ou reduzir a perpetuação das disparidades em saúde. Em sua trajetória profissional, perpassou pelo Instituto de Câncer de Wilmot (WIC), onde atua no momento, sempre apoiada em referências brasileiras importantes como Paulo Freire. No seu trabalho, percebe-se a utilização de estratégias que ultrapassam questões acadêmicas e trazem a comunidade para o protagonismo da pesquisa, permitindo que o processo de translação ocorra apropriadamente. Por fim, define as parcerias com países da América Latina como fundamentais para o desenvolvimento de ações de saúde direcionadas a imigrantes que vivem nos Estados Unidos, uma vez que a variável relações sociais é determinante para a saúde de uma comunidade. A fala da Dra. Cupertino revela, assim, um olhar distinto sobre realidades distantes, mas que podem contribuir para reflexões importantes em um mundo globalizado, no qual intercâmbios são cada vez mais frequentes.
Abstract In this interview with the journal Saúde e Sociedade, Dr. Cupertino talks about her actions to reach people under challenging situations, such as the COVID-19 pandemic. The dialogue aimed to learn about successful experiences capable of erasing or reducing the perpetuation of health disparities. In her professional career, she worked at the Wilmot Cancer Institute (WIC), her current employer, always supported by important Brazilian references such as Paulo Freire. Her research work uses strategies that go beyond academic issues and bring the community to the forefront, enabling an accurate translation process. Finally, she considers the partnerships with Latin American countries as fundamental for developing health actions towards immigrants living in the United States, since the social relations variable is crucial for community health. Dr. Cupertino's testimony thus reveals a distinct look at distant realities, which can contribute to important reflections in a globalized world where exchanges are increasingly frequent.
ABSTRACT
Objective@#To learn about the characteristics of physical activity(PA) and physical fitness, and to provide basis for the health and development of the Tibetan students.@*Methods@#The cluster stratified random sampling was used, and 8 945 Tibetan students in Tibet were selected in May to June, 2019, and were administrated with questionnaire. Independent samples t test, one way ANOVA and Pearson correlation analysis were used.@*Results@#There were significant differences of PA, and physical fitness by gender, grade and living area among Tibetan adolescents ( P <0.05). The PA score of boys(2.79±0.58) was higher than that of girls( 2.51 ±0.56), while the physical fitness level of girls(62.40±25.55) was higher than that of boys(59.26±26.55). The PA score( 2.59 ±0.55) of rural Tibetan children and youth was lower than those of urban areas, while the physical fitness level(61.53±26.53) was only lower than that of county area; the PA score(2.60±0.58) of Tibetan children and youth was the lowest for grade 7 and 9, while physical fitness level(57.62±24.33) was the lowest for grade 5 and 6. PA was not significantly correlated with physical fitness of Tibetan adolescents( r =-0.01， P >0.05).@*Conclusion@#Lack of physical activity and poor physical fitness are observed in Tibetan adolescents. It is suggested that schools, families and society should cooperate in various aspects and actively take measures to improve the physical health level of Tibetan children and adolescents.
ABSTRACT
Objective@#To explore the correlation between serum vitamin D level and glucose and lipid metabolism among primary and middle school students in Inner Mongolia, so as to providing a scientific basis for guiding rational vitamin D supplementation among primary and middle school students in Inner Mongolia Region.@*Methods@#A total of 2 206 students of primary and middle school students from 8 counties (districts) in Inner Mongolia were enrolled for a questionnaire survey, physical examination, and laboratory test by a multi stage stratified random sampling approach.The levels of fasting blood glucose, blood lipid and other related indexes with different vitamin D levels were analyzed, and their correlation was further discussed.@*Results@#The deficiency and insufficiency rates of vitamin D among primary and middle school students were 33.2% and 42.8%, respectively, and the suitable rate was 24.0%. The body mass index (BMI) and waist height ratio (WHtR) of the vitamin D deficiency group [(22.87±7.41) kg/m 2 , 0.46±0.08)]were higher than the insufficiency [(20.59±8.00)kg/m 2, 0.44±0.09)] and suitable group [(18.01±7.38)kg/m 2, 0.43 ±0.08)] ( P <0.05). Compared with the vitamin D suitable group [(3.87±0.85) mmol/L], the total cholesterol (TC) level in the deficiency group [(3.73±0.67)mmol/L] decreased, with a statistically significant difference ( P <0.05). The levels of high density lipoproteins (HDL) in the vitamin D insufficiency[(1.40±0.33)mmol/L] and deficiency groups [(1.34±0.31)mmol/L] were lower than the suitable group [(1.48±0.34)mmol/L], with a statistically significant difference ( P <0.05). The detection rate of hyperuricemia (HUA) in the vitamin D deficiency group (22.95%) was higher than the suitable group (17.20%), with a statistically significant difference ( P <0.016 7). Pearson correlation analysis showed that vitamin D was negatively correlated with BMI and WHtR ( r =-0.23, -0.11), and positively correlated with TC and HDL level ( r =0.06, 0.16) ( P <0.05).@*Conclusions@#The deficiency and insufficiency rates of serum vitamin D among primary and middle school students in Inner Mongolia are high which are associated with several indicators of blood lipids. Therefore, it is recommended to supplement vitamin D preparations in moderation in daily life.
ABSTRACT
Objective@#To identify the 24-hour time allocation patterns of Mongolian junior school students, and to clarify the nature and degree of the influence of the time allocation patterns on the physical fitness of junior school students, so as to provide reference for optimizing and improving the scientific allocation of activity time of young students.@*Methods@#In October 2022, 1 389 Mongolian junior school students aged 13-15 from four schools in Xing an League of Inner Mongolia Autonomous Region were selected with stratified cluster sampling method. The 24-hour time utilization of students were collected by using the questionnaire of "China Time Utilization Survey (CTUS) Time Log in 2017" from October 21 to 22, 2022, and physical fitness was evaluated by using the test data of the National Student Physical Health Standard from September to November 2022. Students time allocation patterns were determined by Latent Profile Analysis with Mplus software, and the correlation between the time allocation patterns and the physical fitness was analyzed by multiple linear regression.@*Results@#The time allocation patterns of Mongolian junior school students could be classified into four types:learning type, screen type, diversity type, and sports type, and the population distribution were 24.7%, 18.3%, 9.9% and 47.1%, respectively. Among all gender and age groups, the sports type received highest total score physical fitness, followed by diversified type, learning type, and screen type ( F =72.25-154.94, P <0.01). The results of multiple regression analysis showed that gender, age, and time allocation patterns were significantly related to the total score of physical fitness ( P < 0.05 ). The total score of physical fitness in learning type, diversity type and sports type groups were all higher than that of screen type ( β =5.63, 12.86, 18.03, P <0.05). Moreover, the sports type showed highest effects on the total score of physical fitness, followed by the diversity type and learning type ( B =0.72, 0.31, 0.19, P <0.05).@*Conclusions@#There is a significant correlation between time allocation patterns and physical fitness of Mongolian junior school students, and those in sports type and diversity type of time allocation achieve better physical fitness, while those in learning type and screen type of time allocation shows relatively poorer physical fitness.In order to promote students physical fitness and healthy development, it is suggested to scientifically arrange students time allocation, increase physical activity time, and reduce sedentary activities that are detrimental to health.
ABSTRACT
Objective@#To analyze the delay on detection, care seeking, diagnosis and treatment of tuberculosis among students in Inner Mongolia Autonomous Region (Inner Mongolia) from 2011 to 2022 and its influencing factors, so as to provide support for the prevention and treatment of tuberculosis among students.@*Methods@#The general demographic indicators of students with tuberculosis in Inner Mongolia from January 1, 2011 to December 31, 2022 were collected from the infectious disease monitoring (new) module of the China Disease Prevention and Control Information System. General characteristics and trend of four types of delayed pulmonary tuberculosis patients in students were analyzed. The influencing factors were analyzed using univariate and multivariate Logistic regressions.@*Results@#From 2011 to 2022, there were 6 032 cases of pulmonary tuberculosis among students in Inner Mongolia. The rates of delayed detection, delayed care seeking, delayed diagnosis, and delayed treatment were 51.71%, 64.01%, 7.82 %, and 2.30%, respectively. The results of multivariate Logistic regression analysis showed that tracking ( OR =1.51) in the patient source,league level diagnosis ( OR =3.16) in the diagnostic institution level,and county level diagnosis ( OR =2.41) were positively associated with delayed discovery ( P <0.05). At the level of diagnostic unit, league city level diagnosis ( OR =2.69), and county level diagnosis ( OR =3.67) associated with more delayed care seeking ( P <0.05). Referral ( OR =1.58) and follow up ( OR =2.55), floating population ( OR =2.05), further consultation with a doctor ( OR =2.11), and no results in imaging manifestations ( OR =2.19) were positively associated with delayed diagnosis( P <0.05). The factors contributing to delayed treatment were referral ( OR =1.84), follow up ( OR =4.91), active screening ( OR =5.46), and floating population( OR =1.95)( P <0.05).@*Conclusions@#From 2011 to 2022, the delay on detection and care seeking for tuberculosis patients among students in Inner Mongolia is at a relatively high level, while the delay in diagnosis and treatment is at a relatively low level but shows an increasing trend. It is necessary to focus on the factors associated with delays in identification, diagnosis and treatment in tuberculosis outbreak in the context of school to prevent or reduce school tuberculosis outbreak.
