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.

Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.
