Should parents limit screen time for young children?

As adults, we are constantly switching between working on a computer, checking our phones, watching TV in the evening — sometimes even playing on a tablet at the same time.

Children are picking up on this behavior, with screen time among children increasing. Data from the Centers for Disease Control and Prevention (CDC) show that children aged 8–10 spend, on average, 6 hours per day in front of a screen. At ages 11–14, this increases to nearly 9 hours a day. A new study from the University of California, Davis (UC Davis) suggests that screens may have critical effects on a child’s development when they begin using them at an early age. The results of study showed that children who began using any screen media (including television, computers, smartphones, and tablets) earlier in life had lower self-regulation abilities. The results showed that this was also true of those who currently used mobile devices (smartphones or tablets or both) more than others in the cohort. Surprisingly, the researchers found exposure to traditional devices, such as television and computers, was not related to self-regulation. They say this may be because messages to provide more child-friendly educational content on TV and warning parents to monitor what their children watch have been effective. It is also likely that the fixed nature of a television and a desktop computer causes less harm than a mobile device, which a person can take anywhere.

What to know about atherosclerosis

Atherosclerosis is the narrowing of arteries due to plaque buildup on the artery walls. Arteries carry blood from the heart to the rest of the body. A thin layer of cells forms a lining that keeps them smooth and allows blood to flow easily. This is called the endothelium. Atherosclerosis happens when the endothelium becomes damaged, due to factors such as smoking, high blood pressure, or high levels of glucose, fat, and cholesterol in the blood. This damage allows a collection of substances, known as plaque, to build up in the artery wall. These substances include fat and cholesterol. Over time, plaque can build up and become hard. If plaque continues to collect, it can block the artery and disrupt the flow of blood around the body. Sometimes, pieces of plaque break open. If this happens, particles from blood cells, known as platelets, gather in the affected area. These can stick together, forming blood clots. A clot can block the artery, leading to life threatening complications, such as stroke and heart attack. Atherosclerosis can affect any artery, but it mainly occurs in the larger, high pressure arteries. Atherosclerosis usually affects older people, but it can start to develop during adolescence. Inside the artery, streaks of white blood cells will appear on the artery wall. Atherosclerosis can be life threatening, but treatment is available. Receiving treatment early can reduce the risk of severe complications. Treatment aims to slow or stop the development of plaque, prevent blood clots forming, and treat symptoms.

 

Options include:

  • lifestyle changes
  • medications
  • surgery

One way to reduce the risk of atherosclerosis is to follow a healthful lifestyle from an early age. For those with atherosclerosis, a doctor can advise on treatment and lifestyle choices to reduce the risk of complications.
