Comparing physical activity assessment methods in the Seasonal Variation of Blood Cholesterol Study

Article Abstract:

Physical activity assessment methods in the Seasonal Variation of Blood Cholesterol Study have been compared. Three measures were evaluated to look at laboratory validity of the Actillume activity monitor and to consider the relative validity of three 24-hr physical activity recalls in quantifying short-term physical activity. The Actillume method discriminated between sedentary and moderate-intensity activities and was correlated to a high degree with oxygen consumption. The three wr-hr physical activity recalls had relative validity comparable to published data from other short-term activity assessments that also used the Baecke Qustionnaire and activity monitors as criterion measures.

Body mass index, but not physical activity is associated with C-reactive protein

Article Abstract:

Results reveal that body mass index is the predictor of the increase in the high-sensitivity c-reactive protein associated with increased risk of first and following coronary events. Data show that current or the past physical activity does not predict the coronary risk.

Estimating physical activity using the CSA accelerometer and a physical activity log

Article Abstract:

Results indicate a fair to moderate agreement between accelerometers and physical activity logs of total activity. Moderate intensity activity shows higher correlations. Among women with lower bone mass index, the moderate intensity activity is independent of age.
