- Abstract
Aim To explore prospectively the correlation between the level of pedometer-determined physical activity at the start of the study and the change in pulse wave velocity from baseline to 4 years later in people with Type 2 diabetes. Methods We analysed data from 135 men and 53 women with Type 2 diabetes, aged 54-66 years. Physical activity was measured with waist-mounted pedometers on 3 consecutive days and the numbers of steps/day at baseline were classified into four groups: <5000 steps/day, 5000-7499 steps/day, 7500-9999 steps/day and ≥10 000 steps/day. Pulse wave velocity was measured using applanation tonometry over the carotid and femoral arteries at baseline and after 4 years. Results The mean (± sd; range) number of steps/day was 8022 (±3765; 956-20 921). The participants with the lowest level of physical activity had a more pronounced increase in the change in pulse wave velocity compared with the participants with the highest. When change in pulse wave velocity was analysed as a continuous variable and adjusted for sex, age, diabetes duration, HbA1c, BMI, systolic blood pressure, pulse wave velocity at baseline, β-blocker use, statin use, unemployment, smoking and diabetes medication, the number of steps/day at baseline was significantly associated with a less steep increase in change in pulse wave velocity ( P=0.005). Every 1000 extra steps at baseline corresponded to a lower increase in change in pulse wave velocity of 0.103 m/s. Conclusions We found that a high level of pedometer-determined physical activity was associated with a slower progression of arterial stiffness over 4 years in middle-aged people with Type 2 diabetes.
