Abstract
The growing prevalence of obesity and its related metabolic diseases, mainly Type 2 diabetes (T2D), has increased the interest in adipose tissue (AT) and its role as a principal metabolic orchestrator. Two decades of research have now shown that ATs act as an endocrine organ, secreting soluble factors termed adipocytokines or adipokines. These adipokines play crucial roles in whole-body metabolism with different mechanisms of action largely dependent on the tissue or cell type they are acting on. The pancreatic β cell, a key regulator of glucose metabolism due to its ability to produce and secrete insulin, has been identified as a target for several adipokines. This review will focus on how adipokines affect pancreatic β cell function and their impact on pancreatic β cell survival in disease contexts such as diabetes. Initially, the “classic” adipokines will be discussed, followed by novel secreted adipocyte-specific factors that show therapeutic promise in regulating the adipose–pancreatic β cell axis.
Abstract
The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.
Objective: The last two decades have witnessed an increase in health care costs due to obesity and related issues among children and adolescents. Childhood obesity is a global phenomenon affecting all socio-economic groups, irrespective of age, sex or ethnicity. The study was done to find the the prevalence of obesity and overweight and their association with socioeconomic status (SES) and the risk factors. Materials and Methods: School based cross sectional study carried out over a period of 4 months in three schools of East Delhi. The study was carried out in 629 school children of 10–18 years of age and belonging to different socioeconomic statuses in schools in East Delhi. The obesity and overweight were considered using an updated body mass index reference. A pre-tested questionnaire was used to determine the Socio-economic status and life style factors. Results: The prevalence of overweight among children was higher in middle socioeconomic status groups as compared to high socioeconomic class in both boys and girls whereas the prevalence of obesity was higher in high Socio economic status group as compared to middle socioeconomic group. The prevalence of obesity as well as overweight in low SES group was the lowest as compared to other group. Conclusion: The findings of this study suggest that the prevalence of overweight and obesity varies remarkably with different socioeconomic development levels.
