“There is an ongoing debate amongst researchers as to why muscle and joint pain, such as neck pain, are so common, and why this seems to be more prevalent among women than men,” says Anna Grimby-Ekman, postdoctoral student and statistician at the Sahlgrenska Academy’s Department of Public Health and Community Medicine.
“We know that physical work with heavy lifting or assembly work that involves a lot of arm-raising above shoulder height can lead to neck pain. By looking at a group whose work is less physically demanding, we can more readily identify other factors that could be implicated and perhaps explain the generally high incidence of neck pain.”
A questionnaire distributed to university students in Sweden – 627 women and 573 men – showed that neck pain is more common in women than men, and that more women than men developed neck pain during the four years of the study. These results were something of a surprise as the researchers had expected that roughly the same number of women as men would develop neck pain in a young group like this, where the majority had yet to start a family and studying meant that the women and men shared a similar working environment.
Questionnaires were distributed to a second group, this time 870 women and 834 men who constituted a representative selection of computer users from the Swedish workforce. Women reported more neck and upper back pain across the range of occupations covered. It was evident in both the computer users and the students that neck pain is affected by psychosocial factors, including the demands of work/studying.
“Perceived stress was more common among the women students than the men, and appeared to play more of a role in the development of neck pain in young women than in men,” says Anna Grimby-Ekman.
Although the results would suggest that more female university students develop neck pain as a result of the factors examined, the studies also indicate that when it comes to young men there may be other factors behind the huge variations in the incidence of neck pain over time.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
