Despite the warnings, 17% of women in the UK and 20% of women in the US still admit to smoking during pregnancy. This often leads to lower birth weight, higher infant mortality, and is linked to learning difficulties, problem behaviour and asthma in childhood.
Most attempts to give up smoking unaided end in failure. The most successful methods of stopping smoking involve a combination of nicotine replacement and behavioural therapy, but there are concerns that nicotine replacement may harm the fetus. Exercise can reduce the cravings experienced by smokers and there is some evidence to show that it can help non-pregnant women to quit.
Michael Ussher and colleagues from St George’s, University of London conducted two pilot studies into whether physical exercise could feasibly help pregnant women quit smoking.
For both studies, pregnant women over 18, who smoked at least a cigarette a day, were recruited 12 to 20 weeks into pregnancy. In one study, women did supervised exercise once a week for six weeks; in the other, women did two sessions of exercise a week for six weeks, then one session a week for three weeks. The participants were also encouraged to do additional exercise on their own and all received advice and counselling towards stopping smoking and becoming more active.
A quarter of the 32 women recruited for the studies gave up smoking before giving birth. This is similar to the number of non-pregnant smokers that quit using nicotine replacement. Furthermore, participants reported other positive benefits including weight loss, improved self-image and reduced cravings.
According to Dr. Ussher, “These results are very encouraging and we are now conducting a randomised controlled trial with 850 women. Regular exercise is ideal for any pregnant women who smoke as it’s obviously safe and the benefits are enormous”.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
