Adherence
High television viewing time is independently associated with elevated 2-hour postchallenge plasma glucose (2-h PG) and reduced insulin sensitivity in women, independent of physical activity levels and adiposity.
If you watch a lot of TV, your blood sugar response to food (specifically 2 hours after eating) may be worse, even if you exercise regularly. This effect is particularly strong in women. To protect your metabolic health, try to break up long periods of sitting with light movement, regardless of your workout routine.
In women, television viewing time had a significant positive association with 2-h PG... Television viewing time was also positively associated with log fasting insulin and log HOMA-%B and inversely associated with HOMA-%S in women.
Why this rating
Large population-based cross-sectional study (n=8,357) with rigorous adjustment for confounders, but lacks causal inference due to cross-sectional design.
