Physical activity level in healthy free-living Japanese estimated by doubly labelled water method and International Physical Activity Questionnaire

Abstract

Objective: To measure total energy expenditure (TEE) for normal healthy Japanese by the doubly labelled water (DLW), and to compare the physical activity level (PAL) among categories classified by the categories used in daily reference intake (DRI), Japan and the International Physical Activity Questionnaire (IPAQ). Subjects and methods: A total of 150 healthy Japanese men and women aged 20-to 59-year-old living in four districts of Japan. TEE was measured by the DLW method, and the PAL was calculated from TEE divided by basal metabolic rate. Simultaneously with TEE measurement, the PAL was assessed employing the categories used in DRI, Japan and IPAQ. Results: The average TEE and PAL were 10.7871.67 MJ/day and 1.7270.22 for males and 8.3771.30 MJ/day and 1.7270.27 for females, respectively. The subjects in the highly active categories assessed by both DRI and IPAQ showed significantly higher PAL compared with less active categories. However, PALs among light and moderate categories by DRI, and insufficient and sufficiently active by IPAQ were not significantly different. Conclusions: In developed countries, highly active subjects could be assessed by a simple questionnaire. However, the questionnaire should be improved to clarify the sedentary to moderately active subjects by assessing carefully very light to moderate physical activity.

Validity of the international physical activity questionnaire short form (IPAQ-SF): A systematic review

“…Of these, 38 papers were excluded for the following reasons: 13 papers used the IPAQ long form; 11 papers validated other measures using the IPAQ-SF as the standard; five papers were not in English; three papers validated a modified version of the IPAQ-SF; three papers were applications of the IPAQ-SF; one paper reviewed properties of physical activity questionnaires among the elderly; one was a comment article and one was a qualitative study translating the IPAQ-SF. Two more papers were identified through the reference lists of the papers reviewed [28,29]. Overall, 23 studies were reviewed in the present paper [17-20,23,25,28-44] and their general characteristics are presented in Table 1.…”

“…Table 3 presents the remaining 7 studies which did not present information from continuous measures of physical activity [28,41], did not present information for the whole sample but in subgroups [40,43], and presented only correlations for specific intensity [38,42,44]. Most studies examined the validity of the IPAQ-SF by reporting the Spearman ρ for the relationship between the scale and the objective physical activity measure(s) and/or the fitness measure(s).…”

“…Table 3 presents the studies that examined the validity of the IPAQ-SF by examining the correlation between the scale and the physical activity/fitness measures at different levels of intensity. This table includes information from 15 studies [20,23,25,28,30,34-38,40-44], 8 of which [20,23,25,30,34-37] presented overlapping data from continuous measures of physical activity are also included in Table 2. For studies that examined the validity of IPAQ-SF at specific levels of intensity, the correlation between the IPAQ-SF and the objective physical activity measures are shown in Table 3.…”

Validation of self-reported energy intake by a self-administered diet history questionnaire using the doubly labeled water method in 140 Japanese adults

“…We invited 40 healthy subjects (20 men and 20 women) aged 20-59 years from each of the four areas to participate, and distributed five subjects equally in each sex and age class of 20-29, 30-39, 40-49 and 50-59 years. Details of study recruitment and enrollment were described previously (Ishikawa-Takata et al, 2007). All subjects providing written informed consent were finally considered eligible for the study.…”
