Short-term behavioral changes in pregnant women after a quit-smoking program via e-learning: a descriptive study from Japan.

Approximately 20% of Japanese women in their reproductive years are smokers. Therefore, in the present study, we report the behavioral changes of woman who undertook a 3 month stop-smoking program. Sixty-six pregnant smokers in the first trimester of pregnancy participated in this study from two hospitals and an obstetric clinic in Japan. Our newly-developed e-learning program uses a cell phone Internet connection service to support pregnant women who want to quit smoking. Using this, service participants were given guidance concerning smoking, and were breath tested for their carbon monoxide levels every 4 weeks for 3 months. An e-learning cessation smoking-support program was maintained throughout the same period. Consequently, 52 of 66 pregnant smokers from three settings began the program, and 48 of 52 eventually completed it. The achievement rate of non-smoking was 71.1% (37/48), and their carbon monoxide exhalation levels significantly decreased from 6.43 ± 4.5 ppm at the beginning to 0.7 ± 1.0 ppm in 1 month, to 0.29 ± 1.08 in 3 months (P < 0.001). These results suggest the effectiveness of our e-leaning program. This paper reports the results of the study.
