More research is needed to understand the dietary implications of prolonged sedentary time, and how these might vary by sex. The Early ACTID intervention did not specifically target sedentary behaviours. However, women in the cohort achieved an average reduction of sedentary time of 24 min/day after 6 months follow-up and furthermore UK-371804 mouse the change in sedentary time was associated with CRP such that for every hour reduction in sedentary time, CRP was reduced by 24%. It has been suggested that improvements in IL-6 and
CRP following lifestyle intervention are dependent upon increases in MVPA , or reductions in weight . However, CRP was reduced at 6 months compared to baseline in women, despite no changes in MVPA and the addition of change in MVPA or weight into the regression model PD0332991 research buy did not attenuate the observed associations. This finding further strengthens
the cross-sectional associations between breaks in sedentary time and CRP observed in the NHANES cohort that were independent of time spent in MVPA . The health benefits of MVPA are well documented and for people with type 2 diabetes include beneficial effects on lipid profiles, glucose control and inflammation . However, people with type 2 diabetes commonly exhibit low levels of physical activity and interventions to increase MVPA often fail to achieve levels suggested to confer metabolic benefits . In the current study, sedentary behaviour accounted for over 60% of the participants waking day , and plausible physiological mechanisms exist to explain the association between prolonged sedentary time and CRP . The accumulating evidence of the detrimental Interleukin-2 receptor health effects of prolonged sedentary time suggest targeting sedentary time may be an alternative strategy for improving the health of people
with type 2 diabetes. These types of interventions may be particularly beneficial for women, who have a heightened state of inflammation and CVD risk and who may find increasing MVPA more difficult. In conclusion, our data suggest that in women with newly diagnosed type 2 diabetes, sedentary behaviour can have a harmful effect on markers of inflammation which may be important for future risk of CVD. Inflammatory profiles were improved following 6 months of lifestyle intervention, with a change in sedentary time predictive of a change in CRP for the women only, a finding that warrants further investigation. These findings suggest that interventions to reduce sedentary time should be explored as potential ways to reduce chronic inflammation in women with type 2 diabetes. The incorporation of recommendations for reducing sedentary time into national guidelines would provide further impetus for the development of interventions to reduce sedentary time.
