Few studies examine the influence of body mass index (BMI) on sexual risk. The purpose of this study was to determine whether BMI among 704 young mothers (ages 14-25) related to STI incidence and sexual risk. We examined the effect of BMI groups (normal weight, overweight, and obese) at 6 months postpartum on STI incidence and risky sex (e.g., unprotected sex, multiple partners, risky and casual partner) at 12 months postpartum. At 6 months postpartum, 31% of participants were overweight and 40% were obese. Overweight women were more likely to have an STI (OR = 1.79, 95% CI = 1.11-2.89, P < .05) and a risky partner (OR = 1.64, 95% CI = 1.01-2.08, P < .05) at 12 months postpartum compared to normal weight women. However, obese women were less likely to have an STI than normal weight women (OR = .57, 95% CI = .34-.96, P < .01). BMI related to STI incidence and sexual risk behavior. Integrated approaches to weight loss and sexual risk prevention should be explored.
很少有研究探讨体重指数（BMI）对性风险的影响。本研究旨在确定 704 名年轻母亲（年龄在 14-25 岁之间）的 BMI 是否与性传播感染（STI）的发生率和性风险有关。我们研究了产后 6 个月时 BMI 组别（正常体重、超重和肥胖）对产后 12 个月时 STI 发生率和高危性行为（例如，无保护性行为、多个性伴侣、风险性行为和随意性伴侣）的影响。在产后 6 个月时，31%的参与者超重，40%的参与者肥胖。与正常体重的女性相比，超重的女性在产后 12 个月时更有可能感染性传播感染（OR = 1.79，95%CI = 1.11-2.89，P <.05）和高危性伴侣（OR = 1.64，95%CI = 1.01-2.08，P <.05）。然而，与正常体重的女性相比，肥胖的女性感染性传播感染的可能性较小（OR =.57，95%CI =.34-.96，P <.01）。BMI 与 STI 的发生率和性风险行为有关。应该探索综合的减肥和预防性传播感染的方法。
