To study the association of age at menarche with presence of pelvic girdle syndrome in pregnancy.
Population study.
Norway 1999-2007.
A total of 74 973 pregnant women in the Norwegian Mother and Child Cohort Study.
Data were obtained by self-administered questionnaires in weeks 17 and 30 of gestation.
Pelvic girdle syndrome in pregnancy at 30 weeks of gestation, defined as pain in the pubic symphysis in the anterior pelvis and in both sacroiliac joints in the posterior pelvis.
The prevalence of pelvic girdle syndrome was 20.6% (328/1593) in women with menarche before the age of 11, it was 16.3% (3200/22 044) in women with menarche at the age of 12 and 12.7% (1252/9859) in women with menarche after the age of 14 (chi-square test for trend, P < 0.001). The inverse association of age at menarche with pelvic girdle syndrome remained after adjustment for body mass index, maternal age, parity, educational level, previous low back pain, emotional distress and physically demanding work. Women with early menarche and high body mass index had the highest prevalence of pelvic girdle syndrome, but the association of early menarche with pelvic girdle syndrome was similar in women with and without high body mass index.
Early menarche was associated with increased prevalence of pelvic girdle syndrome in pregnancy. Factors associated with early menarche may play a role in the development of pelvic girdle pain.
研究初潮年龄与妊娠骨盆带综合征之间的关系。
人群研究。
挪威，1999-2007 年。
挪威母婴队列研究中共有 74973 名孕妇。
数据来自妊娠 17 周和 30 周时的自我管理问卷。
妊娠 30 周时的骨盆带综合征，定义为前骨盆耻骨联合和后骨盆骶髂关节处疼痛。
初潮年龄<11 岁的女性中骨盆带综合征的患病率为 20.6%（328/1593），初潮年龄为 12 岁的女性患病率为 16.3%（3200/22044），初潮年龄>14 岁的女性患病率为 12.7%（1252/9859）（趋势 χ²检验，P<0.001）。调整体重指数、母亲年龄、产次、教育水平、既往腰痛、情绪困扰和体力劳动后，初潮年龄与骨盆带综合征之间的负相关关系仍然存在。初潮早且体重指数高的女性骨盆带综合征患病率最高，但初潮早与骨盆带综合征的关联在体重指数高和低的女性中相似。
初潮年龄与妊娠骨盆带综合征的患病率增加有关。与初潮早相关的因素可能在骨盆带疼痛的发生中起作用。
