A recent study published in the Journal of the American Heart Association reveals that minimal television viewing may help mitigate heart disease risks for individuals with varying genetic susceptibilities to Type 2 diabetes. Researchers analyzed health records from 346,916 United Kingdom adults, discovering that limiting daily TV time to one hour or less could potentially reduce the likelihood of developing atherosclerotic cardiovascular disease.
The study examined participants’ genetic risk scores for Type 2 diabetes and their self-reported television viewing habits. Researchers found that individuals with high genetic risk for Type 2 diabetes who watched television for one hour or less daily had a lower 10-year probability of developing cardiovascular complications compared to those with prolonged viewing times.
Specifically, participants who watched television for two or more hours daily experienced a 12% higher risk of atherosclerotic cardiovascular disease, regardless of their genetic predisposition. Conversely, those with medium and high Type 2 diabetes genetic risk showed no increased risk when their daily TV viewing was restricted to one hour or less.
Lead researcher Youngwon Kim emphasized that Type 2 diabetes and sedentary lifestyles are significant risk factors for cardiovascular diseases. The study provides crucial evidence suggesting that limiting sedentary behaviors, particularly television viewing, could be an effective preventive strategy for heart health.
While the research offers valuable insights, researchers caution that the findings are based on a predominantly white British population and may not be universally applicable across all demographic groups. The study underscores the importance of lifestyle modifications in managing cardiovascular disease risks, particularly for individuals with genetic predispositions to Type 2 diabetes.
