摘要:OBJECTIVE: Short-sleep insomnia is associated with increased risk of diabetes.
The role of altered insulin secretion and action in this association is poorly
understood. DESIGN: Observational study. SETTING: Academic clinical research
center. PARTICIPANTS: Nondiabetic individuals with insomnia (mean [standard
deviation] age 48 [9] y, body mass index 25.6 [3.9] kg/m(2)) with sleep, n = 14) and > 6 h of sleep (n = 14) during overnight laboratory
polysomnography. MEASUREMENTS AND RESULTS: Standard oral glucose testing was used
to assess glucose tolerance, beta-cell function (homeostasis model assessment
[HOMA-B]; second-phase insulin secretion) and insulin resistance (HOMA-IR;
insulin sensitivity index). There was no significant difference in hemoglobin A1C
and fasting or 2-h blood glucose concentrations between sleep groups. Short-sleep
insomnia sufferers had lower fasting and postchallenge serum insulin
concentrations associated with lower estimates of fasting and glucose-stimulated
insulin secretion, and increased insulin sensitivity. CONCLUSIONS: Individuals
with short-sleep insomnia appear to have higher indices of systemic insulin
sensitivity and secrete less insulin without changes in overall glucose
tolerance. CITATION: Vasisht KP; Kessler LE; Booth JN; Imperial JG; Penev PD.
