Tablets and smartphones can cause people to slouch and tilt their head downward for long periods of time. Now, new findings reveal who is most at risk of developing neck strain from this habit — sometimes known as iPad neck — and why time spent using devices is not the biggest factor.

Carried out by the University of Nevada, Las Vegas along with researchers from hospitals and physical therapy centers across Southern Nevada, the new study surveyed 412 participants (135 men and 275 women) who used touchscreen tablet computers.

Some 70 percent of female tablet users develop ongoing pain in their neck and shoulders compared to just 30 percent of men, a US study found.

New US research has found that neck pain caused by using iPads and tablets could be affecting women more than men -- and that poor posture is the biggest factor contributing to pain.

The Department of Physical Therapy at a Nevada university has conducted a study that suggests that bad posture when using a tablet causes permanent neck and shoulder pain. Health problems of this nature are called iPad neck.

The answer is likely yes—especially if you're a young adult or a woman. "iPad neck"—persistent pain in the neck and upper shoulders caused by slouching or bending into extreme positions while using tablet computers—is a growing problem among Americans, according to a new UNLV study.
