Abstract:
Objective Understanding the risk factors of female infertility among child-bearing aged women, in Nanchang area. Methods A hospital-based matched case-control study was carried out in Nanchang. Matched by age ( ±2 years old) , 383 pairs of cases and controls were recruited and studied. Database was established with EpiData 3.0 software. Both cases and controls were interviewed face to face, with a uniformed questionnaire. Conditional logistic regression model was used for univariate and multivariate analysis on SPSS 11.5 to estimate odds ratios (OR) and 95% confidence intervals (CI). Results Data from multiple conditional logistic regression analysis showed that the risk factors of infertility would include pelvic inflammatory diseases (0R=7.078, 95% Ch 3.462-14.467),post-abortion complications' history(0R=3.674, 95% CI: 1.690-7.986), drug treatment history (0R=23.576, 95% Ch 12.324-45.102), dysmenorrhea (0R=1.622, 95% CI: 1.161-2.266), pain from sexual intercourse (0R=2.447, 95% CI: 1.201-4.986), monthly frequency of sexual intercourse (0R=1.416,95% CI: 1.048-1.913)and mental stress (0R=2.146, 95% CI: 1.662-2.771). The protective factor of infertility, however, was level ofeducation(0R=0.522,95%Cl:0.391-0.696).
