Objective To analyze the burden of atherosclerotic cardiovascular disease(ASCVD)attributable to lifestyle and metabolic factors in China from 1990 to 2021 and predict its future trends,providing evidence for public health prevention and control.Methods Based on the Global Burden of Disease(GBD)2021 database,we extracted disability-adjusted life years(DALYs)of ASCVD attributable to 7 key risk factors:dietary,low physical activity,smoking,high body mass index(BMI),high fasting blood glucose,high low-density lipid cholesterol(LDL-C),and hypertension.Age-standardized DALY rates(ASDR)were also calculated to account for variations in age structure,and an ARIMA model was applied to predict future trends.Results ① Overall trend analysis showed the leading risk factor for ischemic heart disease(IHD)shifted from dietary risks in 1990 to hypertension in 2021,while hypertension and smoking remained the primary risk factors for ischemic stroke(IS)and peripheral artery disease(PAD),respectively.② In BRICS nations,hypertension was the dominant risk factor for both IHD and IS,whereas in China,smoking and high fasting blood glucose continued to be the major drivers of PAD burden.③ Sex-specific analysis revealed that hypertension was the leading risk factor for IHD and IS in both males and females.For PAD,smoking was the main risk factor in males,while high fasting blood glucose was for females.Age-stratified analysis revealed that in the 15-49 age group,dietary,high LDL-C and smoking were the primary factor for IHD,IS and PAD,respectively;in the 50-69 group,dietary predominated IHD risk,hypertension IS,and smoking PAD;and among those aged≥70 years,hypertension was the leading risk factor for both IHD and IS,and high fasting blood glucose was for PAD.④ ARIMA model forecasted that by 2035,DALYs for IHD,IS,and PAD will increase to 82.816 million,46.808 million,and 0.192 million person-years,respectively.Conclusion The ASCVD burden attributable to lifestyle and metabolic factors continues to rise in China from 1990 to 2021,and is projected to further increase by 2035.Countermeasures We suggest that current prevention and control priorities are enhanced management of metabolic factors,tailored interventions by sex and age,promotion of healthy lifestyles and tobacco control,and establishment of an integrated system of prevention-treatment-rehabilitation-research.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To analyze the risk factors associated with the occurrence of rectal neuroendocrine tumors (RNETs) and construct a risk prediction model. Methods Clinical data of patients who underwent electronic colonoscopy were collected. The clinical information on patients with and without RNETs were compared, and potential risk factors for RNETs were identified. Binary logistic regression was performed to analyze the relevant risk factors and construct a risk prediction model. Results Among 164 patients, 66 were diagnosed with RNETs, and 98 who did not have such a condition were randomly selected. Univariate logistic regression analysis revealed that age, fatty liver, anxiety and depression, total cholesterol, triglyceride levels, and carcinoembryonic antigen (CEA) were significant factors influencing the occurrence of RNETs (P<0.05). Multivariate logistic regression analysis identified age (P=0.015), anxiety and depression (P=0.031), cholesterol level (P=0.009), fatty liver (P=0.001), and CEA (P<0.001) as independent risk factors for RNETs. The participants were randomly divided into training and test sets at a 7:3 ratio. The training set was used to construct a nomogram-based risk prediction model, and the testing set was used for internal validation. The area under the curve values for the training and testing sets were 0.843 and 0.772, respectively (P>0.05). These findings indicate a good discriminative performance. The calibration curves for the training and testing sets were in good agreement with the 45° standard line, which suggests that the predicted probabilities were consistent with the actual outcomes. Decision curve analysis showed that the model provided a high net benefit within a threshold range of 0.2 to 0.7 for clinical decision making. Conclusion Young age, fatty liver, high CEA levels, high cholesterol levels, and anxiety and depression are independent risk factors for RNETs. The nomogram model constructed based on these risk factors exhibits a strong capability to predict the occurrence of RNETs, and clinical intervention can be considered based on the predicted probability values.
