Objective: To explore physical health status and influencing factors of preschool children in Tibet, so as to provide a scientific reference and theoretical basis for the healthy development of physical fitness. Methods: Data were collected from children (3-6 years old) of Xizang national physical fitness monitoring, and a total of 1 521 preschool children were recruited who received questionnaire survey and physical fitness test. Independent sample t-test and one-way ANOVA were used to compare the differences in physical fitness indexes of preschool children in different groups. Chi square test and binary Logistic regression model were used to analyze the factors affecting physical health of preschool children. Results: The total qualified rate of physical fitness was 79.75%, among which the excellent rate was 3.16%, the good rate was 15.12%, the qualified rate was 61.47% and the unqualified was 20.25%. From the perspective of BMI, the excellent physical fitness rate (3.74%) and good physical fitness rate ( 17.47% ) were highest in healthy weight preschool children, and the qualified physical fitness rate of overweight preschool children (69.03%) was higher than that of obese (55.88%) and healthy weight preschool children (60.68%)( χ 2=53.56, P <0.01). From the perspective of ethnic, Tibetan children s physique proficiency (3.69%), good rate ( 17.13% ) than with the elevation of the Han nationality (0.74%, 5.88%), fraction defective (16.97%), lower than that of Han nationality (35.29%) ( χ 2=53.71, P <0.01); The results of chest circumference, skinfold thickness, body fat percentage, tennis throw distance, continuous jump of both feet, sitting forward bend and balance beam walking of Tibetan children were higher than those of Han children, and the results of quiet heart rate and standing long jump were lower than those of Han children ( t = 2.72 , 10.95, 9.66, 3.68, 3.88, 8.04, 3.56, 8.70, -4.39 , -4.40, P <0.01). Binary Logistic regression analysis showed that Tibetans ( OR =2.29), breastfeeding ( OR =1.51), body dynamics outdoor daily exercise duration 30-90 min (30-<60 min ;OR = 2.03 ; 60-90 min: OR =2.22) were positively correlated with physical health of preschool children ( P <0.05). Conclusions The total physical qualification rate of preschool children aged 3-6 years old in Tibet is lower than the national average. Ethnic group, feeding pattern during infancy, and physical activity are all factors that affected the physical fitness of preschool children in Tibet. It is of great significance to improve the physique of preschool children in Tibet to promote their sustainable and healthy development.

Objective:To examine the physical health status and factors affecting individuals aged 60-69 years in certain regions of Tibet.Methods:The study analyzed data collected from 824 individuals aged 60-69 from the Xizang national physique monitoring.Chi-square test and binary logistic regression were used to identify factors that affect the physical health of this age group.Results:The study evaluated the physical fitness of elderly individuals aged 60 to 69 years old in three regions of Tibet.The results indicated that only 11 cases(1.3%)of participants had excellent physical fitness, while 47 cases(5.7%) had good physical fitness, 394 cases(47.8%)were qualified, and 372 cases(45.1%)were unqualified.The study also found significant differences in physical fitness based on age( χ2=8.367, P=0.039), sex( χ2=22.168, P<0.001), urban/rural location( χ2=12.282, P=0.006), region( χ2=60.358, P<0.001), and body mass index(BMI)( χ2=105.134, P<0.001). Specifically, individuals aged 60-64 years old had a higher proportion of qualified physique than those aged 65-69 years old.Women had better physical fitness than men, and individuals living in urban areas had better physical fitness than those in rural areas.Moreover, participants from Lhasa and Nagqu regions had better physical fitness than those from Nyingchi.Obese elderly individuals had worse physical fitness than those with normal weight(all P<0.05 for all). The study found that female gender( OR=1.765, 95% CI: 1.284-2.425), being a Lhasa( OR=2.799, 95% CI: 1.677-4.672)or Naqu resident( OR=2.730, 95% CI: 1.677-4.445), and engaging in regular exercise( OR=1.845, 95% CI: 1.078-3.160)were protective factors for physical health among individuals aged 60-69 years old.However, not working( OR=0.503, 95% CI: 0.289~0.876)and obesity( OR=0.108, 95% CI: 0.066-0.177)were identified as risk factors for physical health in this age group.Additionally, the analysis revealed significant differences in fitness ratios based on exercise frequency( χ2=18.760, P<0.001)and exercise time( χ2=15.485, P<0.001). Specifically, the fitness ratio of individuals who exercised 1-2 times and 3-4 times a week was significantly higher than that of non-exercisers.The fitness ratio of elderly individuals who exercised for 30 to 60 minutes per session was significantly higher than those who exercised for less than 30 minutes.Furthermore, those who exercised 3-4 times per week had a fitness ratio 2.58 times higher than those who did not exercise at all( P<0.05). Conclusions:This study conducted in Nyingchi, Lhasa, and Nagqu of Tibet found that 45.1% of individuals aged 60-69 years had an unqualified physique.There was a negative correlation between non-employment and BMI≥28 kg/m 2 with physical health, whereas female gender, residing in Lhasa or Nagqu, and engaging in regular physical exercise showed a positive correlation.The study suggests that physical exercise for 30-60 minutes, 3-4 times a week, can significantly improve the proportion of qualified physical fitness among the elderly.

ObjectiveThis paper used the AGREE Ⅱ guideline evaluation tool to evaluate the quality of 14 clinical guidelines for acute myocardial infarction，aiming to provide reference for the formulation and improvement of the guidelines. MethodsClinical guidelines and expert consensus related to acute myocardial infarction were searched by web search. The search period ranges from January 1，2019 to November 1，2024 in CNKI，VIP，Wanfang Data，SinoMed，Web of Science，OVID， the International Guidelines Collaboration Network （GIN），the UK National Institute for Health and Clinical Excellence （NICE），Yimaitong， and other platforms. Three researchers independently screened the literature and used AGREE Ⅱ to score the screening results. After ensuring that the researchers have a consistent understanding of each guideline，the quality of the guidelines was evaluated. After that，the ratings were analyzed by layer according to the issuing agency，category，method of formulation，and funding situation and compared longitudinally by rating time. The clinical guidelines and expert consensus were compared in terms of content and evidence. ResultsA total of 14 guidelines and consensus were included. The results of AGREE Ⅱ in the six areas in descending order were scope and purpose （62.82%±10.43%），rigor （62.40%±12.77%），editorial independence （62.11%±22.26%），participants （61.42%±11.65%），clarity of expression （59.98%±9.62%），and application （52.94%±16.90%） . Eleven of the guidelines were at level B， and three were at level A. In the stratified analysis，the score of the guideline formulated by the Chinese Medical Doctor Association was lower. There was little difference between the scores of Chinese/Western and Western medicine guidelines. The average score of the guidelines was higher than the consensus. Funded guidelines and consensus scores were higher. In the longitudinal comparison，the highest number of guidelines were developed in 2020 and 2021，while those developed in 2023 scored the highest. In the differential comparison analysis，the content of the guidelines was more comprehensive， and the evidence level was higher，while the content of the consensus was more novel， and the evidence was less. ConclusionThe AGREE Ⅱ score of the clinical guidelines for acute myocardial infarction is generally moderate，and there is room for improvement in terms of applicability. At the same time，the content quality of expert consensus should be improved，and more efforts should be made to develop and apply Chinese medicine guidelines for complications such as heart failure and microcirculatory obstruction after acute myocardial infarction.
