Associations between obesity measures and metabolic risk factors in 203 African women with RA
| Metabolic risk factor | Obesity measure | |||
|---|---|---|---|---|
| BMI | Waist | Waist÷height | Log waist÷hip | |
| Systolic blood pressure | 0.23 (0.09 to 0.37)a | 0.11 (-0.01 to 0.25) | 0.09 (-0.06 to 0.24) | -0.05 (-0.16 to 0.07) |
| Diastolic blood pressure | 0.29 (0.15 to 0.43)b | 0.13 (-0.13 to 0.28) | -0.05 (-0.18 to 0.26) | 0.10 (-0.05 to 0.09) |
| Log triglycerides | 0.11 (-0.06 to 0.25) | 0.27 (0.14 to 0.41)b | 0.28 (0.13 to 0.43)b | 0.14 (0.00 to 0.29) |
| Log HDL cholesterol | -0.02 (-0.19 to 0.14) | -0.22 (-0.33 to -0.08)b | -0.20 (-0.36 to -0.04)a | -0.21 (-0.35 to -0.07)b |
| Log glucose | 0.16 (0.02 to 0.27)a | 0.15 (0.01 to 0.30)a | 0.18 (0.04 to 0.33)a | 0.02 (-0.10 to 0.13) |
Results are expressed as standardized regression coefficients (95% confidence interval) in multivariable models in which age, healthcare center, lifestyle factors, current disease activity (DAS28), cumulative disease activity (log deformed joints), prednisone use, hypothyroidism and hormone replacement therapy as well as antihypertensive, lipid and glucose lowering agents upon entering of blood pressure, lipid and glucose parameters as independent variables, respectively, were controlled for. Significant associations are shown in bold. aP-value < 0.05; bP-value < 0.01. BMI, body mass index; HDL, high-density lipoprotein; Log, logarithmically transformed.
