**P < 0.01; ***P < 0.001; ^aconditional logistic regression with age, self-perceived psychological stress, hypertension, smoking status, diabetes, hyperlipidemia, occupation, leisure time physical activity, WHR, and family history of stroke included in the model; ^bpermanent self-perceived stress during the last year or longer; ^cregular, moderate physical activity of at least 4 h/week.

SD = standard deviation; WHR = waist to hip ratio.
