A sedentary lifestyle characterized by excessive screen time and lack of physical activity is a significant health risk factor for U.S. children, particularly in relation to the development of:

• A. sensorineural hearing loss
• B. cardiovascular disease
• C. muscular dystrophy
• D. COPD

Answer: (B)

A sedentary lifestyle with excessive screen time contributes to cardiovascular disease risk in children because inactivity often leads to obesity and metabolic changes that strain the heart and blood vessels. When activity is low, energy balance shifts toward weight gain, increasing fat, especially around organs, and raising blood pressure, cholesterol abnormalities, and insulin resistance. These factors together promote early changes in blood vessels and heart function, setting the stage for heart disease later in life. On the other hand, regular physical activity helps maintain a healthy weight, improves blood pressure and lipid levels, and enhances insulin sensitivity, reducing cardiovascular risk. While inactivity can affect overall health, the choices shown that are most directly linked to these cardiovascular risk processes are rooted in how movement supports heart and vascular health. Sensorineural hearing loss is typically due to noise exposure or genetics, muscular dystrophy is a genetic muscle disease, and COPD is a chronic lung condition usually associated with smoking, not a typical outcome of a sedentary lifestyle in children.
