Table 3 Adjusted HRs of all-cause and CVD-related deaths related to physical activity and MetS status among people younger than 65 years olda

From: Even low level of physical activity is associated with reduced mortality among people with metabolic syndrome, a population based study (the HUNT 2 study, Norway)

  1. aMetS, metabolic syndrome; HR, hazard ratio; CI, confidence interval; MetS, metabolic syndrome; CVD, cardiovascular disease; bparticipants who reported high physical activity levels and did not have metabolic syndrome served as the reference group. HRs are adjusted for age (continuous), sex (men and women), marital status (married or unmarried, widow or widower, divorced or separated), education level attained (≤10 years, 11 to 14 years, ≥15 years or unknown), alcohol consumption (frequency during past two weeks: none, one to four, at least five, total abstainer or unknown), smoking status (never, former, current or unknown), occupational activity (mostly sedentary, much walking, much walking and lifting or heavy physical work).
