WEDNESDAY, March 12, 2014 (HealthDay News) -- Nicotine patches
don't seem to help pregnant women quit smoking, a new study has
The study included 402 pregnant women in France who smoked at
least five cigarettes a day. The women, who were 12 to 20 weeks'
pregnant, were randomly selected to use either 16-hour nicotine
patches or inactive placebo patches until they gave birth.
The study participants also received counseling to help them
quit smoking and were assessed monthly. Only 5.5 percent of the
women in the nicotine patch group and 5.1 percent of those in the
placebo group quit smoking entirely, the investigators reported in
the March 11 online edition of the
The researchers also found that women in the nicotine patch
group had significantly higher blood pressure than those in the
placebo group. This suggests that future studies looking at
nicotine replacement therapy in pregnant smokers should consider
blood pressure, the study authors noted in a journal news
"These are disappointing results, and should encourage efforts to evaluate new approaches that are both drug- and non-drug-related," Dr. Ivan Berlin, of the Hopital Pitie-Salpetriere-Universite in Paris, and colleagues concluded. "In the absence of evidence-based drug interventions, behavioral support remains the core intervention to help pregnant smokers to quit."
Counseling was delayed during the first two weeks of the study
and may explain why both groups of women had low rates of success
in quitting smoking, Leonie Brose, of the Institute of Psychiatry
at King's College London, said in an accompanying editorial.
"It may be too early to abandon the option of [nicotine-replacement therapy] entirely," she wrote. "However, a much greater effort is still needed to identify, test and deliver more effective treatments for pregnant smokers who struggle to quit."
