It is with interest that we read the recently published article titled " Effects of Scheduled Exercise on Cancer-Related Fatigue in Women with Early Breast Cancer " [1]. We are interested in the reported levels of physical activity levels found with the IPAQ-SF in this cancer population. Research has shown that physical activity levels in the cancer population at diagnosis are in line with nonc...

PURPOSE Simple instruments are needed to assess habitual physical activity (PA) in obese subjects. In a multicenter European obesity project, we tested whether PA assessments by two questionnaires were correlated and similarly associated to selected obesity-related variables. METHODS A total of 757 obese subjects (75% female; age 37.1 [7.9] yr, BMI 35.5 [4.9] kg.m(-2), mean [SD]) completed th...

OBJECTIVE Little is known about the influence of age, gender and language on the measurement properties of the long International Physical Activity Questionnaire (IPAQ). The aim was to validate the long IPAQ in adults aged 18-84 in the German-, French- and Italian-speaking parts of Switzerland, focusing on differences between gender, age groups and language regions. METHODS This cross-section...

Vanu, Inc. has demonstrated analog FM two way radio and digital APCO Project 25 waveforms on an iPAQ-based handheld software radio. The iPAQ contains a low-power 206 MHz StrongARM processor that is used for all signal processing. This paper explains the software approaches used and lessons learned from implementing the waveforms on this platform. Commercial and public safety applications of the...

BACKGROUND Evidence suggests that Latina women appear to be less physically active than women of other racial/ethnic groups. This study evaluated how different domains of physical activity (PA) contributed to overall levels of PA among low-income Latinas, the validity of Latinas' self-reported PA, and potential moderators of self-report bias in PA. METHODS A community sample of 105 Latinas (m...

BACKGROUND AND AIMS The International Physical Activity Questionnaire (IPAQ) was issued in 2005 by the WHO as an international standard for the evaluation of physical activity (PA) [1-11]. The Italian Association for Cardiovascular Prevention and Rehabilitation (GICR-IACPR) is promoting nationwide calls for action aimed at the implementation of cardiovascular (CV) prevention guidelines. The awa...

Self-report measures of physical activity (PA) are easy to use and popular but their reliability is often questioned. Therefore, the general aim of the present study was to investigate the association of PA questionnaires with accelerometer derived PA, in a sample of adolescent boys. In total, 191 pubertal boys (mean age 14.0 years) completed three self-report questionnaires and wore an acceler...

BACKGROUND There are challenges for researchers and clinicians to select the most appropriate physical activity tool, and a balance between precision and feasibility is needed. Currently it is unclear which physical activity tool should be used to assess physical activity in Bronchiectasis. The aim of this research is to compare assessment methods (pedometer and IPAQ) to our criterion method (A...

BACKGROUND Due to the large mortality from inactivity-related non-communicable diseases in low- and middle- income countries, accurate assessment of physical activity is important for surveillance, monitoring and understanding of physical (in)activity epidemiology in many of these countries. Research on relative performance of self-report physical activity instruments commonly used for epidemio...

OBJECTIVE To explore issues associated with measuring physical activity using the International Physical Activity Questionnaire (IPAQ)-long form in adults living in a mid-sized Brazilian city. METHODS A stratified random sampling procedure was used to select a representative sample of adults living in Rio Claro. This yielded 1572 participants who were interviewed using the IPAQ-long form. The...
