Objective: To compare the consistency between bioelectrical impedance analysis (BIA) and dual energy X ray absorptiometry (DXA) in measuring body composition among Tibetan children and adolescents and to explore the applicability of BIA in plateau region, so as to provide scientific and convenient body composition measurement support among children and adolescents. Methods: From May to June, 2022, a total of 344 Tibetan children and adolescents aged 6-17 years were selected from Golmud Municipal National Middle School and Changjiangyuan Nationality Primary School in Qinghai Province by cluster sampling method, and their fat mass, fat mass percentage and lean mass were measured by DXA and BIA. The consistency and correlation between the two methods were assessed by using the Wilcoxon rank-sum test, Spearman correlation analysis, intraclass correlation coefficient (ICC), and Bland-Altman analysis. Results: DXA measured fat mass and fat mass percentage were significantly higher than those obtained by BIA (6-12 years old: Z =9.91, 11.28; 13-17 years old: Z =9.02, 10.21), while lean mass and lean mass percentage were significantly lower than BIA results (6-12 years old: Z =-11.60, -11.30; 13-17 years old: Z =-10.77, -10.36) (all P < 0.05 ). The two methods showed strong correlations in fat mass and lean mass (all r >0.80, all ICC >0.90), but exhibited poor agreement in fat mass percentage and lean mass percentage (6-12 years old: Lin s CCC =0.64, 0.41; 13-17 years old: Lin s CCC = 0.79 , 0.35). Bland-Altman analysis showed that the difference between the two methods was negatively correlated with the average value in FM%(6-12 years old: r =-0.75, 13-17 years old: r =-0.79, both P <0.01). Conclusion BIA and DXA show high consistency in measuring body fat mass and lean body mass in Tibetan children and adolescents, although some bias is still present in certain individuals.

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.

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.
