Objective: The neighbourhood built environment may affect walking behaviour of elders. However, such effects remain underexplored, especially in an Asian context. We examined associations of perceived environmental attributes with overall and neighbourhood-specific walking for transport in a sample of Chinese elders residing in Hong Kong, an ultra-dense Chinese metropolis. Design: Cross-sectional observational study using a two-stage stratified sampling strategy. Setting: Hong Kong, China. Subjects: Chinese-speaking elders (n 484), with no cognitive impairment and able to walk without assistance, residing in thirty-two selected communities stratified by socio-economic status and walkability, were interviewer-administered validated measures of perceived neighbourhood environment and walking for transport. Results: Much higher levels of transport-related walking (mean 569 (SD 452) min/ week) than found in Western samples were reported. The degree of perceived access to shops, crowdedness, presence of sitting facilities and easy access of residential entrance were independently positively related to both frequency of overall and within-neighbourhood walking for transportation. Infrastructure for walking and access to public transport were predictive of higher frequency of transport-related walking irrespective of location, while the perceived degree of land-use mix was predictive of higher levels of within-neighbourhood walking.

“…In doing so, we used validated exposure and outcome measures adapted for the target population (13,18,19) . Both frequency and total minutes of transport-related walking were examined since the level of access and diversity of destinations in a neighbourhood may have greater effects on frequency than duration of transport-related walking.…”

“…Although IPAQ-LF has been validated against accelerometry in many countries, these validation studies typically used small samples (3,5,9,27,37) and/or examined only relative agreement (9,37) rather than both relative agreement (correlation) and absolute disagreement (absolute difference) between measures (3,5). Examining both is important because relative agreement does not capture systematic bias (i.e., overestimation or underestimation of self-reported PA and SB).…”

“…Accelerometry data are usually converted into time spent in SB and specific intensity levels of PA (light, moderate, and vigorous) using preestablished cut points (15) and compared with their self-report counterparts. Although IPAQ-LF is meant to gauge moderate-to-vigorousintensity PA (MVPA; corresponding to Q3 METs), better concordance of IPAQ-based total and moderate-intensity PA (MPA) with corresponding accelerometry-based variables has been observed when the latter also included light-intensity activities (G3 METs) as defined by the Freedson cut points (the cut points that have been used in the original multicountry validation study of the IPAQ) (5,9,12,23). This finding indicates that respondents might overestimate the intensity of their activities and/or that the accelerometer cut points for adults developed by Freedson et al may not be appropriate for certain subgroups.…”

“…Although the respondents_ ability to accurately recall PA bout length has been questioned (39), only two studies have examined the agreement of IPAQ-LF estimates of PA with accelerometry-based PA accumulated throughout the monitoring period and PA accumulated through Q10-min bouts (5,17). Identifying the accelerometrybased variables that yield the best agreement with the variables derived from IPAQ-LF administered in different countries would help to understand how participants selfreport PA and identify PA profiles that accelerometers may underestimate.…”

. Purpose: Understanding factors that influence accurate assessment of physical activity (PA) and sedentary behavior (SB) is important to measurement development, epidemiologic studies, and interventions. This study examined agreement between self-reported (International Physical Activity Questionnaire-Long Form [IPAQ-LF]) and accelerometry-based estimates of PA and SB across six countries and identified correlates of between-method agreement. Methods: Self-report and objective (accelerometry-based) PA and SB data were collected in 2002-2011 from 3865 adult participants in eight cities from six countries (Belgium, Czech Republic, Denmark, Spain, United Kingdom, and United States). Between-method relative agreement (correlation) and absolute disagreement (mean difference between conceptually and intensity-matched IPAQ-LF and accelerometry-based PA and SB variables) were estimated. Also, sociodemographic characteristics and PA patterns were examined as correlates of betweenmethod agreement. Results: Observed relative agreement (relationships of IPAQ-LF with accelerometry-based PA and SB variables) was small to moderate (r = 0.05-0.37) and was moderated by sociodemographic (age, sex, weight status, and education) and behavioral (PAtype) factors. The absolute disagreement was large, with participants self-reporting higher PA intensity and total time in moderate-tovigorous-intensity PA than accelerometry. Also, self-reported sitting time was lower than accelerometry-based sedentary behavior. After adjusting for sociodemographic and behavioral factors, the absolute disagreement between pairs of IPAQ-LF and accelerometry-based PA variables remained significantly different across cities/countries. Conclusions: Present findings suggest systematic cultural and/or linguistic and sociodemographic differences in absolute agreement between the IPAQ-LF and the accelerometry-based PA and SB variables. These results have implications for the interpretation of international PA and SB data and correlate/determinant studies. They call for further efforts to improve such measures. Key Words: INTERNATIONAL PHYSICAL ACTIVITY QUESTIONNAIRE, LONG FORM, INTERNA-TIONAL, SOCIODEMOGRAPHIC FACTORS, MEASUREMENT, EXERCISE, SEDENTARY TIME P revalence data for physical activity (PA) and sedentary behavior (SB) are now available for dozens of countries based on self-report surveys (1,2,18). The validity and the between-country comparability of these data rely on survey items having the same meaning across cultures and languages and capturing relevant behaviors that are prevalent in specific populations (24). The International Physical Activity Questionnaire (IPAQ) was developed for international use and has evidence of reliability and validity (9). Although the IPAQ-Short Form has been most often used for international prevalence studies (1,2), the IPAQ-Long Form (IPAQ-LF) has also been used in international research, especially in research focused on domain-specific PA and studies of the environmental correlates of PA and SB (6,9).

Objective. To identify and evaluate the measurement properties of self-report physical activity instruments suitable for patients with osteoarthritis (OA).Methods. We conducted a comprehensive 2-stage systematic review using multiple electronic databases, from inception until July 2018. In the stage 1 review, we sought to identify all self-report physical activity instruments used in individuals with joint pain attributable to OA in the foot, knee, hip, or hand. In the stage 2 review, we searched for and appraised studies investigating the measurement properties of the instruments identified. In both stages of the review, we screened all articles for study eligibility criteria, completed data extraction using the Qualitative Attributes and Measurement Properties of Physical Activity questionnaire checklist, and conducted methodology quality assessments using a modified COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) checklist. Measurement properties for each physical activity instrument were evaluated and combined, using narrative synthesis.Results. In the stage 1 review, we identified 23 unique self-report physical activity instruments. In the stage 2 review, we identified 54 studies that evaluated the measurement properties of 13 of the 23 instruments identified. Instrument reliability varied from inadequate to adequate (intraclass correlation coefficient ≥0.7). Instrument construct and criterion validity assessment showed small to moderate correlations with direct measures of physical activity. Instrument responsiveness was assessed in only 1 instrument and was unable to detect changes in comparison to accelerometers.Conclusion. Although many instruments were identified as being potentially suitable for use in patients with OA, none demonstrated adequate measurement properties across all domains of reliability, validity, and responsiveness. Further high-quality assessment of self-report physical activity instruments is required before such measures can be recommended for use in OA research.
