Supportive text messages can double the chance of someone successfully quitting
smoking, according to UK researchers.
Just over 10% of 2,900 smokers who received encouraging texts such as "you can
do it" had quit after six months, but only 4.9% of a similar number who did not
have the same support gave up.
The study, published in The Lancet, called for texts to be included in services
to help people kick the habit.
Other scientists said a text service could be offered globally.
According to government statistics two-thirds of UK smokers say they want to
stop.
This study looked at 5,800 of them. Supportive texts were sent to 2,915 of the
smokers for six months. The rest received only messages thanking them for
taking part.
They were sent five texts a day for the first five weeks and then three a week
for the next 26 weeks.
Participants could also text back for specific advice when they had cravings or
had lapsed back into smoking.
Sample text messages
"To make things easier for yourself, try having some distractions ready for
cravings and think up some personal strategies to help in stressful situations"
"This is it! - QUIT DAY, throw away all your fags. TODAY is the start of being
QUIT forever, you can do it!"
"Quick result! Carbon monoxide has now left your body!"
"Day4=Big day - cravings still strong? Don't worry tomorrow will be easier!
Keep your mind & hands busy."
"Cravings last less than 5 minutes on average. To help distract yourself, try
sipping a drink slowly until the craving is over."
"Don't feel bad or guilty if you've slipped. You've achieved a lot by stopping
for a while. Slip-ups can be a normal part of the quitting process. Keep going,
you can do it!"
Saliva tests for cotinine, which is made when nicotine is broken down by the
body, were taken to determine if people had really given up.
After six months, 10.7% of those receiving texts had quit - double the
proportion among those doing it on their own.
Dr Caroline Free, who led the txt2stop trial at the London School of Hygiene
and Tropical Medicine, said: "Text messages are a very convenient way for
smokers to receive support to quit.
"People described txt2stop as being like having a friend encouraging them or an
angel on their shoulder.
"It helped people resist the temptation to smoke."
The World Health Organization says nearly six million die each year because of
smoking, mostly in low and middle-income countries.
Dr Derrick Bennett and Dr Jonathan Emberson, both from the University of
Oxford, said text messages could be used to help people around the world.
"The lessons learned from the txt2stop trial could... not only provide a new
approach to cessation in high-income and middle-income countries, but could
also provide a useful starting point for implementing behavioural change in
resource-poor settings."
It has also been suggested similar text messages could be used to help people
modify other behaviour.
