Research Abstract	The subjects were 52 smoking pregnant women during the first trimester (under 22 weeks), who possessed a mobile telephone and showed willingness for participation in the designed program. The counseling and education for the cessation of smoking was carried out to the subjects every four weeks at health checkup, for three months. Expired gas carbon monoxide (CO) concentration was measured at the same time. After the 3-month non-smoking intervention, 37 subjects maintained the non-smoking situation, 11 subjects could not stop smoking, and 4 quit the program due to miscarriage. The expired gas CO concentration during the program participation significantly decreased from the base line value of 8.14±6.1 ppm to 2.52±4.3 ppm after one month, and to 1.62±3.6 ppm after three months (p<0.01). The average baseline CO concentration of the subjects who maintained non-smoking was 6.4±4.6 ppm, which was lower than that of the subjects who continued smoking (12.1±7.2 ppm) (p<0.01).
