In a literature review and meta-analysis of cohort studies published in JAMA, researchers examined the association between TV viewing and type 2 diabetes, fatal/nonfatal heart disease, and all-cause mortality.

The studies were high powered, with thousands of participants. For every 2 hours of TV watching per day, the relative risk increased 20% for type 2 diabetes, 15% for cardiovascular disease, and 13% for premature mortality.

Watching more than 3 hours per day increased the risk of mortality, while the correlations between time spent viewing TV and type 2 diabetes risk and cardiovascular disease were linear.

For every 2 hours of TV viewing, the estimated absolute risk differences for type 2 diabetes was 176 cases per 100,000 persons per year, 38 cases of fatal cardiovascular disease per year, and 104 deaths for all-cause mortality per year.

Many prospective studies by other researchers have shown that TV viewing is linked with biological risk factors including obesity, adverse lipid levels, and clustered cardiovascular risk.

While watching television, people often munch on food and are also exposed to advertising for unhealthy foods. The authors took these factors into consideration and found that there was a small attenuation in risk for type 2 diabetes but not in risk for heart disease or all-cause mortality after adjusting for dietary variables.
