Logistic regression analysis was applied and results were expressed as odds ratios (OR) and 95% confidence intervals (95%CI). RESULTS: Maternal age of> 35 years was a risk factor [OR 2.98; 95%CI: 1.07,8.26] and walking> 2.5 hours/day was a protec¬tive factor [OR 0.31; 95%CI: 0.11, 0.92] for second trimester spontaneous abortions after controlling for confounding factors.
