Women who want to quit smoking need every advantage they can get.
Now, a new study finds that timing a quit attempt around certain points
in the menstrual cycle may increase the chances of success.
Women have a tougher time
According
to background information from the study, only about one in 10 smokers
who quit are still smoke-free after a year, and women have a tougher
time quitting than men, even if they smoke the same amount as men.
In
the new study, Canadian researchers tracked outcomes for 34 men and
women who smoked more than 15 cigarettes a day. They found that the
women's craving for nicotine was strongest during their periods.
That
may be because declines in levels of the hormones oestrogen and
progesterone boost nicotine withdrawal symptoms and also boost the
activity of brain circuits associated with craving, the researchers
said.
The results suggest that women who want to quit smoking may have a
better chance of success if they try to kick the habit after they
ovulate, when their levels of oestrogen and progesterone are elevated,
according to study lead author Adrianna Mendrek of the University of
Montreal.
Sex hormones might play a role
"Taking the menstrual cycle into consideration could help women to stop smoking," she said in a university news release.
The study was published recently in Psychiatry Journal.
According
to the study authors, prior research found that female rats became
addicted to nicotine and other substances more quickly, and worked
harder for the same dose, compared to male rats. This suggests that sex
hormones might play a role in addiction, Mendrek's team said.
However,
each smoker is unique in terms of tobacco use, personality, personal
history, social situation and environment, Mendrek added.
"Stress, anxiety and depression are probably the more important factors to take into consideration," she noted.
