Adherence
High levels of sedentary behavior, specifically television watching, independently predict adverse cardiovascular biomarkers (lower HDL, higher LDL, higher leptin) regardless of the individual's level of physical activity.
Treat television watching as a distinct health risk factor separate from your exercise routine. Even if you are physically active, high hours of TV watching are linked to worse cholesterol and leptin levels. To optimize your cardiovascular biomarkers, you should aim to minimize sedentary screen time in addition to maintaining your physical activity.
The average number of hours of television watching assessed in 1994 was significantly positively associated with low density lipoprotein cholesterol and significantly inversely associated with HDL cholesterol and apolipoprotein A1.
