“…Daily records were excluded if the pedometer was worn for less than 8 h or >60 000 steps were reported (n=11). Average daily steps was calculated for participants with a minimum of 4 days readings (n=2269), consistent with other studies 32 33. In this sample, daily steps were significantly correlated with the PWC 170 cardiorespiratory fitness test (Spearman's r =0.2, p<0.001), with self-reported total physical activity (males: r =0.38, females: r =0.28), and with leisure activity ( r =0.21) and active commuting ( r =0.18) among females, but not males ( r =0.00 and r =0.08, respectively) 34…”

“…The number of pedometer steps recorded in the log each week was averaged to obtain a 7-day daily average. The steps were weighted, however, to reflect differences in steps taken according to wear time (a weighted average was produced for a 24-h period) (24).…”

Research into the accuracy of self‐reported measures used to quantify physical inactivity has been limited. The purposes of the current report were to examine the reliability of a survey question assessing time spent watching television and to describe associations between television watching and physical activity and health risk factors. Data from this cross‐sectional investigation were obtained from a study designed to evaluate a physical activity module for potential use in the 2001 Behavioral Risk Factor Surveillance System. Participants were 93 men and women (aged 45.9 (15.4) years) who answered the question pertaining to television watching during an initial visit and three follow‐up visits to the study center. Intra‐class correlation coefficients (ICCs) between administrations of the survey question were used to assess test‐retest reliability. Spearman rank order correlation coefficients were used to examine the associations of television viewing with physical activity and health risk factors. The test‐retest reliability of the television‐watching question suggested moderate agreement (ICCs of 0.42 and 0.55 over a 3‐week and 1‐week period, respectively). After adjustment for age and sex, reported television‐watching hours were positively associated with BMI (P = 0.0002), percentage fat (P = 0.0001), and light‐intensity physical activity (P = 0.006) and negatively associated with cardiorespiratory fitness (P = 0.004) and moderate‐intensity and hard‐intensity physical activity (P = 0.03 and P = 0.003, respectively). Increased time spent in sedentary behaviors has been identified as a major modifiable risk factor in the development of chronic diseases and conditions. The single‐item survey question evaluated in this study was shown to be a reliable measure of television watching and was associated with physical activity and health risk factor outcomes.

Vigorous physical activity and carotid distensibility in young and mid-aged adults

Although physical activity (PA) improves arterial distensibility, it is unclear which type of activity is most beneficial. We aimed to examine the association of different types of PA with carotid distensibility (CD) and the mechanisms involved. Data included 4503 Australians and Finns aged 26-45 years. Physical activity was measured by pedometers and was self-reported. CD was measured using ultrasound. Other measurements included resting heart rate (RHR), cardiorespiratory fitness (CRF), blood pressure, biomarkers and anthropometry. Steps/day were correlated with RHR (Australian men r = -0.10, women r = - 0.14; Finnish men r = -0.15, women r = -0.11; P<0.01), CRF and biochemical markers, but not with CD. Self-reported vigorous leisure-time activity was more strongly correlated with RHR (Australian men r = -0.23, women r = -0.19; Finnish men r = -0.20, women r = -0.13; P < 0.001) and CRF, and was correlated with CD (Australian men r = 0.07; Finnish men r = 0.07, women r = 0.08; P < 0.05). This relationship of vigorous leisure-time activity with CD was mediated by RHR independently of potential confounders. In summary, vigorous leisure-time PA but not total or less intensive PA was associated with arterial distensibility in young to mid-aged adults. Promotion of vigorous PA is therefore recommended among this population. RHR was a key intermediary factor explaining the relationship between vigorous PA and arterial distensibility.
