Abstract
Background Despite being a preventable disease, the prevalence of obesity is rising progressively worldwide. However, the prevalence of obesity and its associated factors among older adults remains unclear in Malaysia. The aim of this study was to determine the prevalence of obesity and its associated factors among older adults who voluntarily attended the health screening programs, which were part of the Malaysian HEalth and Well‐Being AssessmenT (My‐HEBAT) Study. Methods Cross‐sectional study was conducted among Malaysian adults, aged ≥60 years. A standardized self‐administered questionnaire was used to gather information regarding socio‐demographic status, personal, family and medical history. Anthropometric indices, blood pressure and physical examinations were conducted on site. Venous blood samples were collected for lipid profile and blood glucose analysis. Participants with BMI of ≥30 kg/m2 or < 30kg/m2 were classified as obese or non‐obese respectively. Age was categorized into three subgroups: 60–69, 70–79, and ≥80 years old. The factors associated with obesity among older adults were then identified using multiple logistic regression. Results A total of 716 older adults aged ≥60 years (mean ± SD: 66.6 ± 6.0 years) were recruited. The prevalence of obesity among older adults was 15.8%, while higher prevalence was found among females (42.9%) compared to males (38.3%). The prevalence of obesity decreased with increasing age (48.5% in 60–69 years, 20.8% in 70–79 years, and 11.8% in ≥80 years). Conclusion The prevalence of obesity among Malaysian population is higher than that of worldwide prevalence. Current national health promotion and educational programs should focus on identifying factors associated with obesity, and promotion of healthy lifestyle with obesity should be improved and modified, particularly for older adults in Malaysia.

Abstract
Obesity has become a global health concern. It increases the risk of several diseases, such as type 2 diabetes mellitus, nonalcoholic fatty liver disease, and certain cancers, which threatens human health and increases social economic burden. As one of the most consumed beverages, tea contains various phytochemicals with potent bioactive properties and health-promoting effects, such as antioxidant, immune-regulation, cardiovascular protection and anticancer. Tea and its components are also considered as potential candidates for anti-obesity. Epidemiological studies indicate that regular consumption of tea is beneficial for reducing body fat. In addition, the experimental studies demonstrate that the potential anti-obesity mechanisms of tea are mainly involved in increasing energy expenditure and lipid catabolism, decreasing nutrient digestion and absorption as well as lipid synthesis, and regulating adipocytes, neuroendocrine system and gut microbiota. Moreover, most of clinical studies illustrate that the intake of green tea could reduce body weight and alleviate the obesity. In this review, we focus on the effect of tea and its components on obesity from epidemiological, experimental, and clinical studies, and discuss their potential mechanisms.

Abstract
The medical application of glucagon-like peptide-1 receptor (GLP-1R) agonists is ever-growing in scope, highlighting the urgent need for a comprehensive understanding of the mechanisms through which GLP-1R activation impacts physiology and behavior. A new wave of research aims to elucidate the role GLP-1R signaling in glia plays in regulating energy balance, glycemic control, neuroinflammation, and oxidative stress. Once controversial, existing evidence now suggests that subsets of glia (e.g., microglia, tanycytes, and astrocytes) and infiltrating macrophages express GLP-1R. In this review, we discuss the implications of these findings, with particular focus on the utility of both clinically available and novel GLP-1R agonists for treating metabolic and neurodegenerative diseases, enhancing cognition, and combating substance abuse.
