A feasibility study of activity tracking devices in pregnancy

Table 5 Comparison of median energy expenditure between the Pregnancy Physical Activity Questionnaire and activity tracking device

Median energy expenditure (MET-h/week)	Self-report^a Median (range)	Activity Tracking Device Median (range)	P-value ^b	P-value ^c
28 weeks (n = 23)	212 (22–992)	234 (200–281)	0.66	< 0.001
36 weeks (n = 14)	233 (86–907)	218 (151–273)	0.38	< 0.001

^aMET-h/week derived from self-reported activity from Pregnancy Physical Activity Questionnaire
^bP-value from Wilcoxon signed rank test
^cP-value from Pitman’s test for equality of variance with Spearman correlation
