Logistic regression analysis for sarcopenia indices
| HbA1c (%) | |||||||
|---|---|---|---|---|---|---|---|
| <6.5 | ≥6.5 and <7.0 | ≥7.0 and <8.0 | ≥8.0 | ||||
| OR (95% CI) | P | OR (95% CI) | P | OR (95% CI) | P | ||
| Low skeletal muscle index | Reference | 3.29 (1.31–8.23) | 0.011 | 2.61 (1.09–6.24) | 0.030 | 5.35 (2.07–13.86) | <0.001 |
| Weak grip strength | Reference | 1.07 (0.55–2.07) | 0.834 | 1.46 (0.80–2.67) | 0.221 | 1.95 (1.00–3.80) | 0.050 |
| Slow gait speed | Reference | 0.66 (0.37–1.16) | 0.153 | 1.00 (0.60–1.65) | 0.994 | 1.16 (0.65–2.06) | 0.612 |
Total n = 746. Low skeletal mass index: <7.0 kg/m2 for men, <5.7 kg/m2 for women; weak grip strength: <26 kg for men, <18 kg for women; slow usual gait speed: <1.0 m/s. Adjusted factors were age, sex, body mass index, exercise habit, serum albumin, oral antihyperglycemic drugs, insulin therapy and cardiovascular diseases (ischemic heart diseases, cerebrovascular diseases and peripheral artery diseases). Full results of the logistic regression analyses are shown in Table S3. HbA1c, glycated hemoglobin; CI, confidence interval; OR, odds ratio.
