Abstract Objectives To compare physical activity (PA) reported through pedometer registrations (step counts) with PA reported in four different questionnaires; to compare step count thresholds (7500, 10 000 and 12 500 steps/d) with the PA guideline of 30 min of moderate to vigorous PA (MVPA) per day. Subjects A sample of 310 healthy adults, mean age 38·7 (sd 11·9) years, volunteered to participate. Forty-seven per cent was male and 93 % of the sample was employed. Methods PA was assessed by… 
Correlation between average number of steps per day and the six-minute walk test in asymptomatic adults and elderly
The objective of this study was to evaluate the correlations between the habitual physical activity levels (HPAL) measured by accelerometry, the distance walked during the 6-minute walk test (6MWD)
Reliability and validity of the International Physical Activity Questionnaire-Short Form for older adults in Vietnam.
TLDR
The Vietnamese translated version of IPAQ-SF appears to be a reliable and reasonably valid instrument to assess and monitor habitual physical activity for older adults in Vietnam.
Objective and Subjective Investigation of Physical Activity Levels and Its Relation with Socio-Demographic Characteristics among Medical Students
TLDR
The PA of medical students at different years of medical training was different based on both IPAQ-SF and pedometer, which shows the need to pay attention to the special needs of students in terms of PA at each stage.
Pedometers as an effective tool for measuring physical activity in young females in Saudi Arabia
TLDR
Pedometers can also be a useful tool to promote physical activity in a population of Arab young female students, where walking is the most usual form of exercising.
Comparison of physical activity estimates using International Physical Activity Questionnaire (IPAQ) and accelerometry in fibromyalgia patients: The Al-Andalus study
TLDR
The results suggest that the long self-administrated International Physical Activity Questionnaire is a questionable instrument to assess physical activity in patients with fibromyalgia, and physical activity measurement in Fibromyalgia patients should not be limited solely to self-reported measures.
Evaluating physical activity: the AQAP questionnaire and its interpretation software.
The Influence of Monitoring Interval on Data Measurement: An Analysis of Step Counts of University Students
TLDR
The sample used in this study was drawn from a population of university students to examine the influence of the monitoring interval and alternate starting days on step-count activity patterns and indicated that any starting day except Sunday is satisfactory as long as a minimum of four days of monitoring are used.
Physical activity in climacteric women: comparison between self-reporting and pedometer
TLDR
Comparing the two methods, the frequency of inactive women is higher when assessed by pedometer than by the International Physical Activity Questionnaire - short version, and the opposite occurs in active women.
Convergent validity of the International Physical Activity Questionnaire (IPAQ): meta-analysis
TLDR
Some differences in degree of convergent validity across PA categories and moderator variables imply that different research conditions should be taken into account prior to deciding on use of the appropriate type of IPAQ.
Concordance between Stages of Behavior Change Questionnaire and IPAQ
A low rate of physical activity (PA) participation is observed worldwide. The identification of feasible and reliable instruments able to accurately measuring PA and help in the development of

Pedometer-Determined Physical Activity and Its Comparison With the International Physical Activity Questionnaire in a Sample of Belgian Adults
TLDR
Step data can discriminate between PA levels reported in the IPAQ, and Belgian population pedometer-determined PA levels are higher than those reported in samples of the United States; however, there is a wide distribution of ambulatory behavior.
Physical activity assessment using a pedometer and its comparison with a questionnaire in a large population survey.
TLDR
The pedometer proved to be useful in assessing physical activity in a large, free-living population and produced an unexpected result: Men with a physically active job engaged in more leisure-time physical activity on the weekend.
Measurement of daily walking distance-questionnaire versus pedometer.
TLDR
The findings suggest that electronic pedometers are useful for examining questions about walking distance on physical activity questionnaires.
But What About Swimming and Cycling? How to "Count" Non-Ambulatory Activity When Using Pedometers to Assess Physical Activity.
TLDR
Suggestions are provided for accounting for non-ambulatory activities in interventions which rely on step count measures.
Descriptive epidemiology of pedometer-determined physical activity.
TLDR
The large standard deviations reflect a wide distribution of ambulatory behavior and important differences are still evident by demographic characteristics, BMI categories, day of the week, and reported engagement in work or sport/exercise.
Pedometer-determined step count guidelines for classifying walking intensity in a young ostensibly healthy population.
TLDR
Pedometer cut-points corresponding to minimal moderate intensity walking were 96 steps/min in men and 107 steps/ Min in women, or roughly 100 steps/Min for both, which translates to approximately 3,000 steps in 30 min of moderate-intensity ambulatory activity for both genders.
Meeting Physical Activity Guidelines and Average Daily Steps in a Working Population
TLDR
This study provides an indication of average daily step counts among adults who do and do not meet physical activity guidelines and some evidence on which to base appropriate "step targets" that might be recommended for health benefits for adults.
A Preliminary Evaluation of a Pedometer-Assessed Physical Activity Self-Monitoring Survey
TLDR
Despite the limitations of initial recruitment, this study provides preliminary information on the acceptability and feasibility of a pedometer-assessed physical activity self-monitoring survey.
The utility of the Digi-walker step counter to assess daily physical activity patterns.
TLDR
Pedometers provide a useful indicator of daily step counts but variability in activity patterns make it difficult to establish step count guidelines that correspond with other public health guidelines.
International physical activity questionnaire: 12-country reliability and validity.
TLDR
Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings.
