Pelvic Pain in Pregnancy (PPP) has been diagnosed increasingly often in Norway. The relation to Low Back Pain (LBP) is unclear.
The answers to 5,400 questionnaires were collected from Norwegian women shortly after delivery, and the occurrence of PPP and LBP in relation to various characteristics was studied.
21% of primipara had had both PPP and LBP, whereas 51% had had neither. The figures in multipara were 31% and 33%. After stratification by parity the frequency of both types of pain decreased with increasing age. The largest occupational risk factor of PPP and/or LBP was having to twist or bend several times an hour. This may be preventable. Partial regression coefficients for parity, smoking, and weight of newborn were significantly larger with PPP than with LBP.
The association of PPP and LBP to occupational exposure was similar. The statistical explanatory pattern, and thus possibly the etiology, is different in the two conditions.
挪威孕期骨盆疼痛（PPP）的诊断越来越频繁。其与腰痛（LBP）的关系尚不清楚。
在分娩后不久从挪威女性中收集了5400份问卷的答案，并研究了PPP和LBP与各种特征的关系。
21%的初产妇同时患有PPP和LBP，而51%两者都未患。经产妇的这两个数字分别为31%和33%。按产次分层后，两种疼痛的发生率均随年龄增长而降低。PPP和/或LBP最大的职业风险因素是每小时必须扭转或弯腰几次。这可能是可以预防的。PPP的产次、吸烟和新生儿体重的偏回归系数显著大于LBP。
PPP和LBP与职业暴露的关联相似。两种情况的统计解释模式不同，因此病因可能也不同。
