Multivariate logistic regression analysis of factors associated with the prevalence of stroke.

<p>The variables included in the analysis were sex (0, female; 1, male), age (0, 35–55 years; 1, over 55 years), ethnicity (0, Han; 1, Manchu), smoking (1, smoking every day for more than one year; 0, otherwise), alcohol intake (1, once at least every day; 0, otherwise), hypertension (1, systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, or the use of antihypertensive drugs; 0, otherwise), body mass index (0, <24 kg/m²; 1, ≥24 kg/m²), ankle-brachial blood pressure index (0, <0.9; 1 ≥0.9), interarm blood pressure difference (0, <15 mmHg; 1, ≥15 mmHg), interankle blood pressure difference (0, <10 mmHg; 1, ≥10 mmHg), total cholesterol (1, ≥5.21 mmol/L; 0, otherwise), triglycerides (1, ≥1.7 mmol/L; 0, otherwise), low-density lipoprotein cholesterol (1, ≥3.3 mmol/L; 0, otherwise), high-density lipoprotein cholesterol (0, <0.9 mmol/L; 1, otherwise), fasting blood glucose (1, ≥6.0 mmol/L; 0, otherwise). A: Adjusted co-variables with <i>p</i> < 0.05 in the univariate analysis and other well-documented risk factors for stroke (smoking status, alcohol intake and family history of stroke) were introduced into the multiple logistic regression models. B: Adjusted covariables with <i>p</i> < 0.05 in the univariate analysis, but excluding hypertension and ankle-brachial blood pressure index, and other well-documented risk factors for stroke (smoking status, alcohol intake and family history of stroke) were introduced into the multiple logistic regression models. Abbreviations: ABI, ankle-brachial blood pressure index; BMI, body mass index; BP, blood pressure; FBG, fasting blood glucose. HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TC, total cholesterol; TG, triglycerides.
