Valid instruments for the assessment of physical activity remains a challenge
in field studies. This study determine the level of agreement between
objectively measured physical activity by ActiHeart® and the international
physical activity questionnaire short form (IPAQ-S) among adolescents
attending schools in the Tlokwe Local Municipality, South Africa. A total of
63 boys and 45 girls aged 15 years were participants in PhysicalActivity and
Health Longitudinal Study (PHALS). Objective physical activity (PA) was
measured by a means of ActiHeart® for seven (7) consecutive days.
Subjective physical activity was assessed with self-reported IPAQ-S. Objective
PA indicated that 93% of the participants were inactive and only 6%
highly active. IPAQ-S showed that 24% were inactive with 57% active. A
non-significant correlation (r = 0.11; p = 0.29) between ActiHeart® measure
of activity energy expenditure (AEE) and total physical activity (IPAQ-S)
was observed. Cohen’s Kappa (k) show poor agreement between the two
measurement instruments, κ 0.011, P < 0.005
