The relationship between duration, bleeding volume, and activity for women in the progress of drug abortion: a cross-sectional study.

Background: To investigate the influential factors associated with abortion time, bleeding volume, pain scores, and anxiety during the progress of drug abortion (DA). Methods： Participants were randomly assigned to: (Ⅰ) The control group was given routine DA education and nursing, and the activity of subjects was not increased.（Ⅱ） The experimental group as same as the control, but appropriately increased their activity time. Results: The mean age was 32.14±0.26 years. Advanced age exhibited positive correlation with abortion duration (rs=0.0102, P <0.05), but a negative association with pain scores (rs=-0.178, P <0.001). Dysmenorrhea emerged as a risk factor for prolonged abortion duration (rs=-0.097, P <0.05), but increase pain scores (rs=0.106, P <0.05) and anxiety levels (rs=0.119, P <0.05). Furthermore, history of cesarean section exhibited a positive influence on pain relief (rs=-0.226, P <0.001) and reduction in anxiety (rs=-0.129, P <0.001) during DA. Conclusions: Women who have a history of vaginal delivery have earlier ovulation time than those who have not given birth, and women who have more activities have earlier ovulation time than those who have less activities under the same conditions;
