As subjective and objective measurement tools have their own shortcomings and advantages,understanding the correlation between two types of measurement tools will help to compare data across studies.The study aims to compare estimates of activity levels and sleep behavior across 4 different types of measyrement tools.We used questionnaires, pedometers,and accelerometers as a research tools.A total of 130 college students from Chia Nan University of Pharmacy were recruited.We found that there are significant differences between different measurement tools. For the estimates from two subjective measures,the greatest differences were found on light physical activity and sedentary behavior (285-416 minutes).For the estimates from two objective tool,the biggest difference were found on calorie consumption (310 calories).For the estimates from subjective and objective measures,the greatest differences were found on light physical activity and sedentary behavior (400-424 minutes).There was a positive correlation between PAR and IPAQ estimate (r=0.43,p<0.001),while there is a positive correlation between caloric estimates from pedeometers and accelerometers (r=0.79,p<0.001).There are positive correlattions betweem PAR and accelerometers on vigorous physical activity,light physical activity, sedentary behavior, MET,and energy expenditure.
