ABSTRACT
Objective:To investigate the association between metabolically healthy obesity(MHO) and atherosclerosis risk among Chinese community population aged 40 or older.Methods:A total of 9 525 participants without cardiovascular diseases (3 621 men and 5 904 women) from Jiading community in Shanghai were enrolled to complete questionnaires, undergo extensive physical examination including brachial-ankle pulse wave velocity (baPWV) and blood pressure (BP) assessment, and laboratory screening. According to body mass index (BMI) and metabolic status, these participants were categorized into 4 groups including metabolically healthy non-obese (MHNO), metabolically unhealthy non-obese (MUNO), MHO, and metabolically unhealthy obese (MUO). High baPWV was defined as baPWV>1 400 mm/s, and high pulse pressure (PP) was defined as PP above fourth quartile of the population. Multivariate logistic regression model was conducted to explore the relationship between MHO and high baPWV as well as high PP after adjusting for confounders. Results:After multivariable adjustment, such as sex, age, current smoking, current drinking, and education, logistic regression analysis showed that MHO was significantly correlated with high baPWV ( OR=1.18, 95% CI 1.02-1.37) and high PP ( OR=1.72, 95% CI 1.43-2.08) in comparison with MHNO. Otherwise, both MUNO and MUO subjects were at higher risk for suffering from high baPWV (MUNO: OR=3.02, 95% CI 2.60-3.50; MUO: OR=3.26, 95% CI 2.87-3.70) and high PP (MUNO: OR=2.56, 95% CI 2.17-3.02; MUO: OR=3.49, 95% CI 3.01-4.06). Conclusion:On the basis of Chinese community population, there was a pronounced correlation between the MHO phenotype and the increased risk of developing atherosclerosis.
ABSTRACT
Early adulthood is a critical stage in life cycle. Weight change during this period boasts several significant physiological features, and is suggested to have an effect on future cardiometabolic health. However, few studies have systematically described the association of weight change in early adulthood with long-term cardiometabolic risk. Therefore, we tried to comprehensively summarize the influence of different weight change patterns during early adulthood on cardiovascular diseases, and discuss some potentials in future research.
ABSTRACT
As the aging process accelerates, cognitive dysfunction has become a significant public health problem. Recently, oxidative stress has been recognized as a critical factor contributing to the pathogenesis of cognitive dysfunction. Therefore, uric acid, as an important antioxidant in vivo, might correspondingly play cognitive protection roles. However, uric acid was regarded as a risk factor for cognitive deterioration in some studies. The uric acid paradox, together with the pathophysiological differences between cognitive disorders, adds to the complexity of their association. So far, the impact of uric acid on cognitive function has been debated. This article tried to review the impact of uric acid on different cognitive disorders and to discuss the possible mechanisms.
