2 years ago @DougManuel Total hours spent on sedentary activities is a derived variable based on leisure time on the computer, leisure time on video games, leisure time watching tv/videos, and leisure time on reading from 2000-2016. For 2017-2018, the sedentary activity is based on screen time at school/work and screen time not at school/work.
Leisure time on video games is not consistent across all age groups: 2000/2001 (age < 19), 2003-2008 (age < 20), 2009-2014 (age <= 25), and 2015/2016 (all ages).
For 2001-2003 and 2015-2018, sedentary variables are total hours/week whereas the remaining cycles are total hours in the past 3 months.
Several studies have assessed sedentary behaviour across CCHS cycles:

What is the name of the variable?
What is the most consistent name for this variable (usually the variable name used from 2007-2014). If this is a derived variable, what is the name of the newly derived variable?
