2.Study reveals no ‘healthy obesity’
Recently, a reporter from Science and Technology Daily learned from the First Affiliated Hospital of Chongqing Medical University that the team of Professor Li Qifu from the Department of Endocrinology of the hospital explored the causal relationship between fat content and death risk based on genetic analysis. There are “healthy lean” and “unhealthy lean” for people with low fat content; but there is no “healthy obesity” for people with too much fat. Relevant research results were published in the international journal “Metabolism”.
This study, based on a large UK Biobank cohort, used two different methods to assess the relationship between total body fat content and risk of death. The researchers first combined genome-wide association studies, polygenic risk scores and Mendelian randomization methods to analyze the relationship between fat content and risk of death. The results showed that there was a linear causal relationship between fat content and all-cause mortality. 1kg/m2, the risk of death increased by 8%. The researchers then used bioelectrical impedance to measure the fat content and analyzed its relationship with the risk of death. The results showed that the fat content and the risk of death were non-linear, that is, too little or too much fat increased the risk of death. (Science and Technology Daily)
3. Shijiazhuang Police: Failure to report mixed positive samples caused the spread of the epidemic, and a nucleic acid testing institution was placed on file for investigation
