You've probably heard that increased TV watching, high-calorie snacking, and decreased physical activity are linked to skyrocketing rates of child obesity. But recent research points to a new culprit: lack of sleep.
"Children who don't sleep enough are at much greater risk for obesity than children who do sleep enough," says Frederick J. Zimmerman, PhD, chair and professor in the Department of Health Services at UCLA School of Public Health, and one of the lead researchers in a recent study.
Nursemaid's elbow means the elbow has slipped out of its normal place at the joint.
The elbow bone (radius) is connected to the elbow joint (humerus) by elastic bands called ligaments. These ligaments grow stronger and tighter as a child grows older. In little kids and babies, the ligaments are still loose. This makes it easy for the elbow to slip out of place.
Your doctor or nurse may use other terms for nursemaid's elbow, such as:
The injury is not often seen in kids older than 5 or 6. That's because as children grow, their bones harden and the ligaments get tighter and thicker. This helps keep the elbow firmly in place.
Girls are slightly more likely than boys to have nursemaid's elbow.
Causes of Nursemaid's Elbow
Nursemaid's elbow can happen if you tug or pull on a child's lower arm or hand, especially if the arm is twisted. It doesn't take much force for the injury to happen. The most common cause of nursemaid's elbow is a pulling-type injury.
Nursemaid's elbow may happen if you:
Catch a child by the hand to stop a fall
Lift a child up by the hands or wrists
Pull a child's arm through a jacket sleeve
Swing a child by the arms or hands
Yank on a child's arm to make him or her walk faster
