Objective: To investigate the nutritional status and influencing factors among Tibetan and Mongolian children and adolescents aged 7-18 years in high-altitude regions, so as to provide evidence for early prevention and control of malnutrition in this population. Methods: From May to June 2022, a cluster sampling method was employed to recruit 1 019 Tibetan and Mongolian children and adolescents aged 7-18 years from two primary and secondary schools in Golmud City. Physical examinations, dietary frequency questionnaires, and physical activity assessments were conducted. Nutritional status was classified as obesity, combined overweight/obesity, underweight, or central obesity according to national standards including Screening for Overweight and Obesity among School-age Children and Adolescents, Screening Standard for Malnutrition of School-age Children and Adolescents, Blue Book on Obesity Prevention and Control in China. Chi-square tests, t-test and Logistic regression analyses were performed to identify factors associated with different nutritional statuses. Results: The detection rates of obesity, combined overweight/obesity, underweight, and central obesity were 8.0%, 18.1%, 5.2%, and 19.7%, respectively. The height of children and adolescents across all age groups was generally lower than the national standard values. Tibetan participants exhibited significantly lower height-for-age Z-scores (HAZ)(9-10, 13-17 years, Z =2.01, 2.78, 4.16, 3.38, 4.12, 3.63, 3.00) and BMI-for-age Z-scores (BAZ) compared to Mongolian participants ( Z =-2.95, -2.47, -2.31, -2.89, -2.14, -2.17)( P < 0.05 ). Multivariate Logistic regression revealed that Mongolian children and adolescents had higher risks of obesity ( OR =2.20) and combined overweight/obesity ( OR = 2.18 ) ( P <0.05). Additionally, insufficient moderate-to-vigorous physical activity (MVPA) was associated with an increased risk of central obesity ( OR =1.48, P <0.05), compared with children and adolescents who meet the standard of MVPA. Conclusions The rates of overweight and obesity among Tibetan and Mongolian children and adolescents in Golmud City are higher, influenced by multiple factors. Nutrition interventions and physical activity strategies tailored to ethnic characteristics should be implemented, with emphasis on promoting MVPA to improve nutritional outcomes in this population.

Since 1986, the WHO has held ten global health promotion conferences covering various health promotion issues and sustainable development worldwide. These sessions have formed a series of consensus and actions that guide promoting health globally. This study analyzed the declarations, reports, and news materials from the ten conferences that studied health promotion action areas, focal topics, actor networks, partnership relationships, and other significant outcomes. It also explored how these conferences contributed to the construction and advancement of global health promotion consensus and actions. The first Global Conference on Health Promotion identified the concept of health promotion and five key action areas, laying the foundation for subsequent conferences and health promotion actions. Over the years, the ten conferences continuously expanded the essence of health promotion, developed partnership relationships, formulated public health promotion policies, and called for health promotion actions. This process culminated in the formation of global consensus and collective actions. The latter conferences have gained significant attention and influence. The conferences offer valuable insights for future global health promotion endeavors and provide global perspectives and pathways for the development of Healthy China.

With the intensification of the global population aging trend, the problem of obesity in the elderly has become increasingly prominent, which is closely related to the increase of the risk of various diseases and mortality.However, there are still many challenges in dealing with this problem.First, body mass index, waist circumference and waist-to-hip ratio, which are widely used for weight assessment, have certain limitations.Secondly, the screening and management of weight-related complications should be strengthened, and management concepts should be established to improve physical function and enhance health outcomes.At the same time, attention should be paid to the management of body composition, especially the monitoring and management of sarcopenia and sarcopenic obesity, which are common in the elderly.In the management of obesity in the elderly, it is necessary to consider the overall health status of patients, living habits and other factors, and formulate lifestyle intervention measures in line with their physiological characteristics.If lifestyle interventions do not work well, the drug regimen should consider the combined effects of cardiovascular, renal, and metabolic syndrome.With the continuous advancement of artificial intelligence technology, weight management in the elderly is expected to improve health outcomes by building risk prediction models through machine learning and enabling precise personalized treatment.This will provide a new strategy and method for solving the problem of obesity in the elderly.

Objective:Overweight and obesity prevalence has increased in low-income countries.This study systematically reviewed the obesity trend,disparities,and prevention and control efforts in Nepal. Methods:We searched PubMed and Google Scholar for articles and reports published between January 1,2004 and December 31,2022.Additional information on National policies and programs related to obesity prevention was retrieved from governmental websites and consultation with relevant experts.Overweight and obesity were defined using the World Health Organization body mass index cut points.Thirty-two studies and reports were included. Results:Overall,overweight and obesity rates increased in all groups in Nepal although nationally representative data remained limited.The combined overweight and obesity(OW/OB)and obesity rates in women aged 15-49 years increased from 8.5％to 22.2％and from 0.9％to 5.1％between 2006 and 2016,respectively.OW/OB and obesity rates in men were 17.1％and 2.5％based on data from the 2016 Demographic and Health Survey.OW/OB rate in under-five children increased from 0.6％to 2.8％between 2006 and 2016.Obesity rates for school-age(5-9 years)boys and girls in 2016 were 2.4％and 2.8％,respectively,and were 1.1％and 1.4％for male and female adolescents aged 10-19 years,respectively.OW/OB prevalence was much higher among women,residents in urban areas and central provinces,and in higher socioeconomic status groups.Projected prevalence of OW/OB and obesity for 2030 in adults aged 15-49 was 44.7％and 8.3％,respectively,while it was 2.2％for OW/OB in preschool children.Policies and direct interventions that specifically focused on obesity prevention and control are limited. Conclusions:OW/OB prevalence in Nepal has increased during the past 1.8 decades,disproportionately affecting population groups.Existing interventions mostly focused on undernutrition with some indirect implications for obesity prevention.In the future,Nepal needs to develop population-based programs for obesity prevention.

Objective:This study analyzed how the 10 Global Conferences on Health Promotion have played a significant role in shaping and promoting a worldwide consensus and actions on health promotion,effectively addressing diverse health challenges that evolved over different periods. Methods:The textual analysis method was used in this study and text encoding was conducted to systematically examine the declarations and reports presented by the 10 Global Conferences on Health Promotion held during 1986-2021.We summarized the themes and key achievements,and key vocabulary in the conference declarations was extracted and analyzed to construct the global health promotion consensus and actions. Results:The fundamental principles of the conferences are to foster consensus and initiate actions in the realm of health promotion on a global scale.The primary purpose and goal are to promote health from regional to global.Significantly,our findings highlight a transition in the primary actors driving health promotion.It underscores a shift in health promotion from being driven primarily by organizations like the World Health Organization,governments,and international bodies,to a more inclusive approach involving non-governmental organizations and the general public.This development implies that health promotion has evolved into a collective global en-deavor,demanding the proactive involvement of various stakeholders,and forging new alliances in public health.Meanwhile,the coronavirus disease 2019(COVID-19)pandemic has further shaped the landscape of health pro-motion,underscoring the need for intensified focus on areas including disease prevention,health education,and the integration of digital health technologies,and emphasizing the importance of a multidimensional,responsive approach in public health initiatives. Conclusions:Sustained collaboration and innovative strategies are pivotal to advancing health promotion globally.Countries,together with public and private entities,should intensify cooperation.Multisectoral collaboration among partners such as healthcare,education,social security,and the industry is vital for health promotion and achieving global health goals.

The incidence rate of anxiety and depression is significantly higher in patients with inflammatory bowel diseases (IBD) than in the general population. The mechanisms underlying dextran sulfate sodium (DSS)-induced depressive-like behaviors are still unclear. We clarified that IBD mice induced by repeated administration of DSS presented depressive-like behaviors. The paraventricular thalamic nucleus (PVT) was regarded as the activated brain region by the number of c-fos-labeled neurons. RNA-sequencing analysis showed that lipocalin 2 (Lcn2) was upregulated in the PVT of mice with DSS-induced depressive behaviors. Upregulating Lcn2 from neuronal activity induced dendritic spine loss and the secreted protein induced chemokine expression and subsequently contributed to microglial activation leading to blood-brain barrier permeability. Moreover, Lcn2 silencing in the PVT alleviated the DSS-induced depressive-like behaviors. The present study demonstrated that elevated Lcn2 in the PVT is a critical factor for DSS-induced depressive behaviors.

Research of healthy life expectancy (HLE) is needed in an aging society and by the Healthy China Initiative. However, China has not developed the HLE policy goal nor published HLE values. Therefore, it is essential to construct the HLE indicator system to guide HLE estimation and research. Based on the definition of health from the WHO and the concepts from the United Nations Sustainable Development Goal, One Health and Active Health, we systematically reviewed the existing international HLE indicators, and initially proposed a novel multi-dimensional HLE conceptual framework and indicator structure according to international function, disability and health classifications and international disease classification framework of WHO. The conceptual framework includes five dimensions-physical, mental, behavioral, social, and environmental health, and the comprehensive indicator for disability-disability index is added. Furthermore, we proposed the HLE indicator structure, including behavioral factors, physiological and pathological reasons, impairment, functional limitation, disability and death. Then we discussed the approaches, types of data, and potential data sources for such research. The results of this study would facilitate HLE research and contribute to the aging society and Healthy China Initiative.

Objectives:To explore obesity prevalence and its association with dietary patterns among Tibetan pastoralists during the urbanization transition in Qinghai Province.Methods:Using an open cohort study design, 1 003 subjects were enrolled at baseline in 2018, 599 were followed up, and 1 012 were newly recruited in 2022. A total of 1 913 adults over 18 years were included in the study, and a questionnaire survey and health examination were conducted. Factor analysis was used to identify dietary patterns, and a mixed-effects model was used to analyze the association between dietary patterns and obesity.Results:From 2018 to 2022, the prevalence rates of overweight, obesity, and central obesity were 27.6%, 33.8%, and 54.6%, respectively. Age-sex-standardized prevalence of obesity and central obesity increased. Three dietary patterns were identified: the modern pattern was characterized by frequent consumption of pork, poultry, processed meat, fresh fruits, sugary drinks, salty snacks, etcetera; the urban pattern was characterized by frequent consumption of refined carbohydrates, beef and mutton, vegetables and eggs, etcetera; and pastoral pattern featured frequent consumption of tsamba, Tibetan cheese, buttered/milk tea, and whole-fat dairy products. After adjusting for demographic characteristics, socioeconomic status, and lifestyle factors, compared with the T1, subjects in the T3 of urban pattern scores were more likely to be overweight ( OR=2.09, 95% CI: 1.10-3.95) and overweight/obese ( OR=1.23, 95% CI: 1.00-1.51), whereas those in the T3 of pastoral pattern scores had a lower risk of overweight ( OR=0.45, 95% CI: 0.24-0.84), obesity ( OR=0.81, 95% CI: 0.69-0.95), overweight/obesity ( OR=0.75, 95% CI: 0.61-0.91) and central obesity ( OR=0.58, 95% CI: 0.38-0.89). Conclusions:Prevalence of obesity and central obesity was high among Tibetan pastoralists during the urbanization transition. Urban dietary pattern was a risk factor for overweight and overweight/obesity, whereas pastoral dietary pattern was a protective factor for overweight, obesity, overweight/obesity, and central obesity. Tailored interventions are needed to improve local people's health.

Objective:This study compared the prevalence,awareness,treatment and control of hypertension and associated factors in China and the United States(US).Methods:Adult data from nationally representative samples were derived from the Chronic Disease and Risk Factors Surveillance in 2010 and 2013 in China and the National Health and Nutrition Examination Survey in 2010 and 2013 in the US.Multivariable logistic and Poisson regression analysis were conducted to assess associations of the four outcomes with body weight status and behavioral factors.Results:Age-standardized prevalence rates of hypertension was 35.7％(95％confidence interval[CI]:35.4％to 36.1％)in 2010 and 29.8％(95％CI:29.4％to 30.2％)in 2013 in China,and 35.3％(95％CI:33.6％to 37.1％)in 2010 and 37.9％(95％CI:36.0％to 39.7％)in 2013 in the US.Among hypertensive participants,the age-standardized rates of treatment were 18.4％(95％CI:17.9％to 18.9％)in 2010 and 23.8％(95％CI:23.1％to 24.6％)in 2013 in China and 54.5％(95％CI:50.3％to 58.7％)in 2010 and 50.9％(95％CI:46.5％to 55.3％)in 2013 in the US;the age-standardized hypertension control rates were 3.2％(95％CI:3.0％to 3.5％)and 5.7％(95％CI:5.3％to 6.0％)in 2010 and 2013 in China and 50.6％(95％CI:46.2％to 55.0％)and 55.3％(95％CI:50.3％to 60.3％)in the US.Obesity was significantly associated with prevalence,awareness and control rates in both countries.Different from the US,obesity was negatively associated with hypertension control in China.Conclusion:Hypertension prevalence in China is similar to that in the US,but the control rate in China was significantly lower.Obesity was a critical risk factor for poor hypertension control in China.

Objective:We examined the association between body mass index(BMI)and body fat percentage(BF％)measured by dual-energy X-ray absorptiometry(DXA)among adults and children in China.Methods:We searched four databases-PubMed,China National Knowledge Infrastructure,Wanfang,and Vip for studies published in the past 22 years.Meta-analysis was conducted using random-or fixed-effect models.Results:In total of 21 studies met inclusion criteria and were included in review,and 17 ot them in meta-analysis.They were conducted across China.Their sample size ranged from 62 to 5 726,and participants'age ranged from 6-80 years.Meta-analysis revealed strong associations between BMI and BF％measured by DXA in adults(pooled r=0.71,95％CI:0.66 to 0.74)and children(pooled r=0.60,95％CI:0.52 to 0.68).The association was stronger in Northern China than in East China in children(β=-0.40,95％CI:-0.65 to-0.14)and in Central China in adults(β=-0.25;95％CI:-0.51 to-0.01).Urban children's BMI was strongly associated with BF％than rural(β=0.19;95％CI:0.04 to 0.35),whereas it was stronger in adults living in rural than in urban(β=-0.35;95％CI:-0.66 to-0.05).Conclusions:BMI was strongly associated with BF％measured by DXA,and the association in children and adults in China varied by residence and region.
