Background - Overweight and obesity are associated with metabolic syndrome and abdominal
obesity, thereby increasing the risk of type 2 diabetes mellitus and
cardiovascular diseases. In Brazil, there are still no precise data on the
prevalence of these disorders, especially among individuals who carry out some
kind of physical activity in public spaces and there are no education and
prevention programs for obesity.
Aim: To investigate the prevalence of metabolic syndrome and obesity among park users.
Methods: A prospective, cross-sectional, descriptive study was conducted with 619
individuals assessed and stratified by profile according to a specific protocol.
The group was characterized as follows: female (50.1%) and mean age =50.6±14.8,
with predominance of individuals aged between 50 and 59 years (26.8%) and with
higher education (68%) and a household income of between 4 and 10 minimum wages
(29.2%).
Results: Regular physical exercise was reported by 78% of the individuals and it was found
that 70.7% were nevertheless of above normal weight: 45% overweight and 25.7%
obese, of whom 20.7% had obesity grade I, 3.9% grade II and 1.1% grade III. The
prevalence of metabolic syndrome was 4.3%, mostly in men (6.3%). Arterial
hypertension and type 2 diabetes mellitus were detected in 17.8% and 5.5%,
respectively. In view of the influence of obesity on the occurrence of type 2
diabetes mellitus and metabolic syndrome, it was found that this association was
not significant for the two conditions (p=0.014 and 0.017, respectively). Conclusion: The findings demonstrate a high prevalence of overweight and obesity in the
studied population, and metabolic syndrome in 4.3%, despite the fact that 70%
reported engaging in regular physical activity.
COVID-19 and obesity are two pandemic diseases that the world is currently facing. Both activate the immune system and mediate inflammation. A sequence of disease phases in patients with severe COVID-19 results in a cytokine storm, which amplifies the subclinical inflammation that already exists in patients with obesity. Pro-inflammatory cytokines and chemotactic factors increase insulin resistance in obesity. Therefore, a greater systemic inflammatory response is establishe, along with an increased risk of thrombotic phenomena and hyperglycemic conditions. These changes further impair pulmonary, cardiac, hepatic, and renal functions, in addition to hindering glycemic control in people with diabetes and pre-diabetes. This review explains the pathophysiological mechanisms of these two pandemic diseases, provides a deeper understanding of this harmful interaction and lists possible therapeutic strategies for this risk group.
Nonalcoholic steatohepatitis is highly prevalent in morbidly obese patients, but there was no positive correlation between aminotransferases and degree of obesity and liver histopathology. Hypertriglyceridemia and waist-hip ratio were positively correlated with the intensity of disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
