Table 3.

Physical activity levels in relation to changing patterns of physical activity during pregnancy (n = 62).

	n (%)	Time spent for PA (hours/week)				Energy expenditure (MET-hours/week)
	n (%)	22 weeks gestation	P value	34 weeks gestation	P value	22 weeks gestation	P value	34 weeks gestation	P value

P value refers to that obtained by the paired t-test unless otherwise stated. ^‡One-way analysis of variance. Comparison of physical activity at 22 and 34 weeks of gestation in the ^†active group, ^††inactive group, ^†††became active group, and ^††††became inactive group. ^a,b,cValues with the same superscript lowercase letter do not represent a significance difference. *p < 0.05.
