In the nested case\u2010control study, the adjusted ORs for overall pelvic pain were 0.9 (0.7\u20131.2) in underweight women, 1.2 (1.1\u20131.4) in overweight women, 1.5 (1.2\u20132.0) in obese women Class 1 (30\u2264BMI&lt;35), and 1.9 (1.3\u20132.8) in obese women Class 2 + 3 (BMI\u226535), all relative to normal weight women. The correspondent ORs for severe pelvic pain were 0.8 (0.6\u20131.2), 1.4 (1.2\u20131.7), 1.7 (1.3\u20132.2), and 2.3 (1.6\u20133.4).
