The impact of taxes on consumption of sugary beverages in Mexicodoi: https://doi.org/10.1136/bmj.m1311researchers recently examined changes in the trend of consumption of soft drinks among Mexican adults three years after the implementation of the sugary and sweet beverage taxThe study, conducted in Mexico between 2004 and 18, surveyed 1,770 people aged 19 years or older to obtain information on consumer beverage consumptionThe main endpoint of the study was changes in soft drink consumption after the implementation of taxationbefore the tax was imposed, more than 50 per cent of participants were moderate lying consumers of soft drinks, while non-soft drink consumers were less than 10 per centAfter the tax was implemented, 43 per cent of the population was classified as a medium or high consumer, and the non-consumer rate increased to 14 per centThree years after the tax was introduced on 1 January 2014, the proportion of non-soft drink consumers increased by 4.7% compared to pre-tax and the proportion of low soft drink suis consumers increased by 8.3%In contrast, the proportion of middle- and high-level soft drinks consumed fell by 6.8% and 6.1%, respectivelyThere was no significant heterogeneity in taxation at different levels of income, but the impact of taxation was greater among participants with secondary education or higher educationthe effects of body mass index in adolescence on cardiovascular, diabetes and tumor risk in later life
doi:https://doi.org/10.1136/bmj.m1203researchers recently assessed the effects of body mass index in adolescence on the risk of developing later liferesearchers collected data from the British Biobank and four large-scale genome-wide association studies (GWAS), which included 453,169 participants, and the GWAS study, which involved more than 700,000 participants, measured their BMI at age 56.5 and reported their BMI at age 10 The main endpoints of the study were coronary artery disease, type 2 diabetes, breast cancer and prostate cancer A single-variable Mendel randomization analysis showed that higher BMI in adolescence was associated with an increased incidence of coronary artery disease (1.49) and type 2 diabetes (2.32) However, based on the multivariate Mendel randomization study, BMI had no significant effect on the risk of coronary artery disease (1.02) and type 2 diabetes (1.16) in adolescence, but higher BMI in adolescence reduced the risk of breast cancer (0.59) and no effect son-in-law of bmi on prostate cancer risk was found in adolescents 3: of prognostic studies in unidentified patients with myocardial infarction
doi: https://doi.org/10.1136/bmj.m1184 unidentified myocardial infarction is a special pathological phenomenon that lacks the acute stage characteristics of myocardial infarction, but pathological changes can be detected by instrument, and researchers recently compared electrocardiograms (UMI-ECG) or cardiac magnetic resonance imaging (UMI-CMR) identified prognosis differences in patients with myocardial infarction, with key results including major heart adverse events, all-cause mortality and cardiovascular mortality in patients diagnosed with UMI-ECG and UMI-CMR Secondary outcomes are the risk of recurrent coronary heart disease, myocardial infarction, stroke, heart failure, and atrial fibrillation meta-analysis included 30 studies, 253,425 participants and 162,1920 follow-up Compared to no myocardial infarction, the risk of all-cause mortality (risk ratio 1.50), cardiovascular mortality (2.33) and major adverse heart events (1.61) increased in UMI-ECG-diagnosed patients, and higher risk of all-cause mortality (3.21), cardiovascular mortality (10.79) and major adverse heart events (3.23) in patients diagnosed with UMI-CMR Compared to patients without myocardial infarction, the absolute risk of all-cause mortality in the umi-ECG-diagnosed population is 7.50 per 1,000 people per year, the absolute risk of cardiovascular death is 11.04, and the absolute risk of major adverse heart events is 27.45 The corresponding data for UMI-CMR are 32.49, 37.2 and 51.96, respectively Source: MedSci Original wonderful comment: Ao commented on 2020-5-10: good article, learn, I will share the (from: MedSci Medicine APP )
