Abstract
PURPOSE OF REVIEW:
Aging of the world population is a major contributor to the growing prevalence of the metabolic syndrome, as older persons are frequently affected by the constellation of cardiovascular and metabolic risk factors that constitute the syndrome. The metabolic syndrome has been related to the increasing prevalence of obesity, which is escalating even among older age groups. The present review covers data on the novel proposed biological mediators of the metabolic syndrome, which are as well linked to the aging process.
RECENT FINDINGS:
Relevant biological mediators of metabolic syndrome and unhealthy aging include sarcopenic obesity, insulin resistance with ectopic fat accumulation, magnesium metabolism alterations, systemic and hypothalamic inflammation, shortening of telomeres length, epigenetics, and circadian rhythm disturbances.
SUMMARY:
Metabolic syndrome is related to increased accumulation of central adiposity and ectopic fat infiltration in the skeletal muscle and the liver, linked to overeating and sedentarism with deleterious consequences in late life. Obesity may be complicated with sarcopenia, which refers to loss of muscle mass, strength, and quality in older populations. Prevention of obesity and metabolic syndrome is a priority through the promotion of healthier lifestyles and policies for sugar and saturated fats, which might be widely implemented.
