摘　　要：Background:A shift from self-reports to wearable sensors for global physical activity(PA)surveillance has been recommended.The conventional use of a generic cut-point to assess moderate-to-vigorous PA(MVPA)is problematic as these cut-points are often derived from non-representative samples under non-ecological laboratory conditions.This study aimed to develop age-and sex-(age-sex)specific cut-points for MVPA based on population-standardized values as a feasible approach to assess the adherence to PA guidelines and to investigate its associations with all-cause mortality.Methods:A total of 7601 participants(20-85+years)were drawn from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Surveys(NHANES).Minutes per week of MVPA were assessed with a hip-worn accelerometer.Counts per minute(CPM)were used to define an age-sex specific target intensity,representing the intensity each person should be able to reach based on their age and sex.Age-sex specific MVPA cut-points were defined as any activity above 40%of the target intensity.These population-and free-living-based age-sex specific cut-points overcome many of the limitations of the standard generic cut-point approach.For comparison,we also calculated MVPA with a generic cut-point of 1952 CPM.Both approaches were compared for assessing adherence to PA guidelines and association of MVPA with allcause mortality(ascertained through December 2015).Results:Both approaches indicated that 37%of the sample met the 150+min/week guideline.The generic cut-point approach showed a trend to inactivity with age,which was less pronounced using the age-sex specific cut-points.Overall mortality rates were comparable using generic cutpoint(hazard ratio(HR)=0.61,95%confidence interval(95%CI):0.50-0.73)or age-sex specific cut-points(HR=0.57,95%CI:0.50-0.66)for the entire sample.The generic cut-point method revealed an age-and sex-related gap in the benefits of achieving 150+min/week of MVPA,with older adults showing an 18%greater reduction in mortality rates than you
