【Abstract】 Objective: To investigate the time to pregnancy of women of childbearing age in Henan Province, and to analyze the related influencing factors so as to provide basis for carrying out health education and raising fertility of women of childbearing age. Methods: 953 women of childbearing age in Henan province who wanted to pregnancy were enrolled in this prospective cohort study by cluster sampling method. Chi square test and ANOVA were used to compare the pregnancy status of different subgroups. Multivariate analysis was performed by Cox proportional hazards model to study the factors influencing time to pregnancy of the women. Results: The average age of these 953 women was 31 years old. The main occupation was peasants and their education level was mainly undergraduates and above. There were 463 women with pregnancy in the following up period and there were 490 women without pregnancy. Compared with that of the young women, time to pregnancy was gradually prolonged with the age, and that of the women in the age of 30-34 years old was the longest(FR=0.547, P<0.05). Compared with that of the peasant women, time to pregnancy of civil servant women was significant shorter(FR=1.460,P<0.05). Compared with that of the women with normal weight, time to pregnancy of obese women was significant longer(FR=0.541, P<0.05). The women with history pregnancy or with irregular menstruation had longer time to pregnancy. Conclusion: It is necessary to carry out reproductive health education targeted at older women, peasant, obese women, women with history pregnancy, and women with irregular menstruation, so as to improve their fertility.更多还原
