Abstract

So what is SB and when do we do it? • SB is <1MET • SB in adults occurs in three phases throughout the day; during transport, occupationally and leisure time. • SB higher in younger, educated, white collar Prevalence: • 50% of population median sitting time >4h/day (Bauman et al., 2011), close to 25% >6 h/day • Very limited evidence occupational sitting time that 30% of full time employed NZ adults occupational sitting 3.5-4 h/day (Statistics New Zealand, 2015 + drawing in Mummery data) Links: • SB linked with increased levels of psychological disorders SB linked with • increases in colon, rectal, ovarian and endometrial cancer often independent of PA • What interested me is SB linked with increased BMI, waist circumference, blood pressure and decreased HDLC, increased cardiovascular events and all-cause mortality (Mummery et al., 2005; Wijndaele et al., 2009; Bertrais et al. 2005; Stamatakis et al. 2011)
