ObjectiveTo investigate the association between serum fasting triglyceride glucose-body mass index （TyG-BMI） and new-onset metabolic dysfunction-associated fatty liver disease （MAFLD） within 10 years. MethodsA retrospective analysis was performed for the data of individuals who underwent physical examination in The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University in 2013， 2018， and 2023 and were not diagnosed with MAFLD in 2013， and a total of 1 340 valid subjects were enrolled according to the inclusion and exclusion criteria. The gbmt package in R 4.3.0 was used to construct the dynamic change trajectory model of TyG-BMI， and four different TyG-BMI trajectory groups were determined， i.e.， the low-level group （n=352）， the medium-level group （n=517）， the high-level group （n=314）， and the extremely high-level group （n=157）. The data on general information and blood biochemical parameters were collected from all subjects and were then compared between groups. The chi-square test was used for comparison of categorical data between groups， and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data with heterogeneity of variance between multiple groups. The Cox regression analysis was used to investigate the association between different TyG-BMI trajectories and the risk of MAFLD， and the receiver operating characteristic （ROC） curve was used to assess the value of TyG-BMI in the diagnosis of MAFLD. ResultsThe cumulative incidence rate of MAFLD increased with the increase in the level of TyG-BMI trajectory， with a cumulative incidence rate of 4.83% in the low-level group， 29.98% in the medium-level group， 61.15% in the high-level group， and 83.44% in the extremely high-level group （P<0.001）， and the cumulative incidence rate of MAFLD in men was significantly higher than that in women （51.34% vs 20.67%， P<0.001）. The multivariate Cox regression analysis showed that increases in the levels of TyG-BMI trajectory， uric acid， diastolic blood pressure， hemoglobin， and alanine aminotransferase were independent risk factors for the onset of MAFLD （all P<0.05）， while the increase in high-density lipoprotein cholesterol was an independent protective factor against MAFLD （P<0.001）. After adjustment for confounding factors， the medium-， high-， and extremely high-level groups had a hazard ratio of 4.430 （95% confidence interval ［CI］： 2.660 — 7.377， P<0.001）， 6.937 （95%CI： 4.110 — 11.708， P<0.001）， and 7.989 （95%CI： 4.616 — 13.827， P<0.001）， respectively. The ROC curve analysis showed that TyG-BMI had the highest diagnostic value， with an area under the ROC curve of 0.859 （95%CI： 0.840 — 0.879）， a sensitivity of 79.8%， and a specificity of 76.3%. ConclusionThe risk of MAFLD increases with the increase in the level of TyG-BMI trajectory， and TyG-BMI can be used as a predictive indicator for MAFLD.

Objective:To explore the impact of the interaction between alcohol consumption and overweight/obesity on the risk of hypertension.Methods:It was a cross-sectional study, and convenient sampling was used to enroll physical examination participants aged 18-60 years from the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, the Affiliated Hospital of Southwest Medical University and Luzhou People′s Hospital from June to November in 2020. All the participants were given questionnaire survey, physical examination and biochemical tests. A total of 5 000 questionnaires were distributed in the study, and 4 878 questionnaires were collected, of which 4 397 (90.14%) were valid. According to the diagnostic criteria for hypertension, the study participants were divided into hypertension group (1 128 cases) and non-hypertension group (3 269 cases), and t-test and chi-square test were used to compare the differences in gender, age, and other data between the two groups; and multivariate logistic regression analysis was used to analyze the association of alcohol consumption, overweight/obesity with the risk of hypertension and the interaction between alcohol consumption and overweight/obesity on the risk of hypertension, and relative excess risk of interaction, attributable proportion of interaction and the synergy index were used to evaluate the impact of the interaction between alcohol consumption and overweight/obesity on the risk of hypertension. Results:Among the 4 397 individuals included in the analysis, 3 116 were male and 1 281 were female, with a mean age of (42.42±8.83) years. The detection rate of hypertension was 25.7% (1 128/4 397). The risk of hypertension in overweight/obese individuals was 2.566 times ( OR=2.566, 95% CI: 2.167-3.038) higher than that of non-overweight/obese individuals, and the risk of hypertension in alcohol consumption individuals was 1.486 times ( OR=1.486, 95% CI: 1.250-1.766) higher than that of non-drinkers. The risk of hypertension in drinking+non-overweight/obesity group, non-drinking+overweight/obesity group, and drinking+overweight/obesity group was 1.468 times ( OR=1.468, 95% CI: 1.112-1.936), 2.538 times ( OR=2.538, 95% CI: 1.968-3.272), and 3.796 times ( OR=3.796, 95% CI: 2.963-4.863) higher than that of non-drinking+non-overweight/obesity group, respectively (all P<0.05). Alcohol consumption and overweight/obesity had an additive interaction effect on the risk of hypertension, and the relative excess risk of interaction, attributable proportion of interaction and the synergy index was 0.791 (95% CI: 0.158-1.424), 0.208 (95% CI: 0.049-0.368), 1.394 (95% CI: 1.030-1.888), respectively. There was no significant multiplicative interaction between alcohol consumption and overweight/obesity on the risk of hypertension ( P>0.05). Conclusions:Alcohol consumption and overweight/obesity are both associated higher risk of hypertension. In addition, there is an additive interaction between alcohol consumption and overweight/obesity on the risk of hypertension.
