Usefulness of a self-reported physical activity questionnaire assessment for Japanese children

Abstract

The study aimed to assess a self-reported questionnaire about physical activity (PA) from the Health Behaviour in School-aged Children (HBSC) using triaxial accelerometer as a criterion. Elementary school boys (N=292) and girls (N=313) in the fourth grade and higher completed the questionnaire and wore an accelerometer for at least 10 h/day for at least 4 days. The phi coefficients of the chi-square test 2-way tables (active/inactive as measured using the HBSC questionnaire × achievement/non-achievement of the recommended 60-min moderate to vigorous PA [MVPA] as measured using the accelerometer) were 0.25 (P<0.001), 0.17 (P=0.009), and 0.08 (P=0.217) for all children, boys, and girls, respectively. The sensitivity and specificity in boys were 82% (95% confidence interval [CI]=78-86%) and 34% (95% CI=26-41%) respectively, while the those of girls were 52% (95% CI=40-63%), 57% (95% CI=55-60%). The positive predictive value in boys was 70% (95% CI=66-73%) and negative predictive value in girls was 83% (95% CI=79-87%). The independent t-test showed that moderate PA (MPA), vigorous PA (VPA), and MVPA min/day of active children were significantly higher than those of inactive children (range of Cohen's d=0.38 to 0.71). Area under the curve (AUC) of the VPA (AUC = 0.60-0.73) in girls was significantly higher than that of the MPA (AUC = 0.52-0.65) and MVPA (AUC = 0.54-0.67). Our results supported that the HBSC self-reported questionnaire has acceptable, but limited agreement for assessing achievement/non-achievement of the MVPA recommendation, and could estimate the differences in the MPA, VPA, and MVPA min/day of children.

Association between physical activity duration and depressive symptoms in adolescents: A longitudinal study in a rural city in Japan

“…Therefore, the actual amount of physical activity might have been underestimated. Although the Health Behavior in School-aged Children Study (HBSC) questionnaire, which was used as a reference in the development of the questionnaire for this study, was confirmed to be valid and reliable [19,34,35], it overestimated moderate-to-vigorous physical activity compared with an accelerometer and reported sexual differences in the accuracy of responses [35]. These factors may have influenced the result in the subanalysis.…”

Estimating model of sedentary behavior with tri-axial accelerometer in elementary school children

“…The equation for locomotive activity can evaluate both ambulation and running, while the equation for nonlocomotive activity is good at estimating irregular motions associated with daily activities, such as sweeping, clearing away, and throwing a ball. This algorithm has previously been used in investi-*Correspondence: hikihara.yuki@it-chiba.ac.jp gative studies such as the validation of MVPA with questionnaire 8) , the contribution of types of physical education to MVPA 9) , and comparisons of MVPA during the school year and summer vacation 10) .…”
