Table 1

Domain-based sitting times and the amount of leisure-time physical exercise by sex (𝑛=6713^∗).

Activities	Men (𝑛=3082)	Women (𝑛=3631)

In a vehicle	59 min (59 min)	43 min (33 min)
Elsewhere	48 min (45 min)	48 min (45 min)
Sum of sitting time***	6 h 46 min (2 h 50 min)	6 h 36 min (2 h 34 min)
	𝑛 (%)	𝑛 (%)
Amount of leisure-time physical exercise****
Practically none	252 (8)	150 (4)
A little	754 (25)	716 (20)
A moderate amount	1369 (45)	1722 (48)
Quite a lot or a great deal	695 (23)	1038 (29)

 * Data from those twin individuals who had no missing values in any of the sedentary domains.
** Data from those twin individuals (𝑛=3970) who reported working full time at the moment of the survey.
***In calculating the total sum of sitting, sitting at office (work) was denoted as zero minutes for those twins (𝑛=2728) who reported not working at the moment of the survey (missing information in 15 individuals).
****Missing information in 17 individuals.
