Data are the means (SE) adjusted for age and sex or N (%). Abbreviations: IVSDT = inter ventricular septal diastolic thickness; LVEDD = left ventricular end-diastolic diameter; LVPWT = left ventricular posterior wall thickness; LVM = left ventricular mass; LVMI = left ventricular mass index; LVH = left ventricular hypertrophy. Padjusted1 : P value adjusted for age and sex. Padjusted2: P value adjusted for age, gender, height, weight, waist circumference, blood pressures, lipids, HbA1c, HOMA-IR, leptin, adiponectin, hs-CRP, smoking, physical activity and sleep quality. *P < 0.05, **P < 0.01, compared with sleep hours ≤7 h. †P < 0.05, ††P < 0.01, compared with sleep hours between 7–9 h.
