Does abnormal insulin action or insulin secretion explain the increase in prevalence of impaired glucose metabolism with age in populations of different ethnicities?

Abstract: Background Age is associated with both impaired glucose and insulin metabolism. To what extent the age-related changes in insulin resistance (IR) and β-cell function contribute to the increase in prevalence of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) is less known, and this is investigated in this study.

“…It remains controversial that whether insulin resistance increases with age [22][23][24]. Szoke et al discovered that aging had no effect on insulin sensitivity, which keep consistent in our finding that age was excluded from the factors affecting log HOMA2-S. An inverse relationship between age and insulin sensitivity was found by Karakelides et al [25].…”

“…In the UK, individuals of South Asian descent, for example, have a substantially higher risk of developing type 2 diabetes compared with individuals of European descent [4]. There is robust evidence that reduced insulin sensitivity contributes to this elevated risk [57]. Beta cell dysfunction is also a plausible aetiological factor explaining elevated risk among South Asian individuals [8, 9].…”

“…The case for reduced insulin sensitivity is well established in South Asians from childhood to adulthood, based on measures such as fasting insulin (FINS) or HOMA insulin sensitivity (HOMA2-%S), which are directly comparable across populations [ 9 16 ]. The role of insulin secretion remains equivocal [ 12 , 14 ]. Reduced insulin secretion (or pancreatic functional reserve) is a plausible aetiological factor in South Asians because fetal undernutrition is common in Asian populations and may lead to reduced growth of the pancreas [ 1 ].…”
