Age at menarche and pregnancy-related pelvic pain

Pelvic Girdle Pain in Pregnancy: A Review

Importance

Pelvic girdle pain is often thought to be a recent phenomenon, but this condition was described as early as 400 BC by Hippocrates. Despite being identified for years, confusion continues about the definition and management of this ailment affecting many pregnancies.

Objective

The purpose of the review is to assess the incidence, etiology, pathophysiology, risk factors, diagnosis, management, and pregnancy outcomes/recovery of current pregnancies, and outcomes of future pregnancies complicated by pelvic girdle pain.

Evidence Acquisition

Electronic databases (PubMed and Embase) were searched from 1980 to 2021 with the only limitation being that the articles were in English. Studies were selected that examined associations between pelvic pain/pelvic girdle pain and pregnancy.

Results

There were 343 articles identified. After reviewing the abstracts, 88 were used in this review. Pelvic girdle pain is a common condition of pregnancy, affecting a reported 20% of pregnant women. The pathophysiology is poorly understood and likely multifactorial, involving both hormonal and biomechanical changes that occur during pregnancy. Several risk factors have been identified. This diagnosis is most commonly made based on symptoms related to pelvic pain during pregnancy. Treatment should be multimodal, including pelvic girdle support, stabilizing exercises, analgesia, and potentially complementary therapies. The effects on future pregnancies are uncertain, although some limited information suggests an increased risk of recurrent PGP in subsequent pregnancies.

Conclusions

Pelvic girdle pain in pregnancy is a common condition that is often overlooked as a normal part of pregnancy but has a significant impact on quality of life during, after, and in subsequent pregnancies. Multimodal therapies are available and are largely low cost and noninvasive.

Relevance

Our aim is to increase the awareness of pelvic girdle pain in pregnancy as a common but often underdiagnosed and undertreated condition.

Generalized joint hypermobility and risk of pelvic girdle pain in pregnancy: does body mass index matter?

Background: Women with generalized joint hypermobility may be at increased risk of pregnancy-related pelvic girdle pain, but evidence is inconclusive. Objectives: In this prospective cohort study of 283 pregnant women in Norway, we aimed to study the association of generalized joint mobility with pelvic girdle pain, and to evaluate if pre-pregnancy body mass index was a modifier of the association. Methods: Generalized joint hypermobility was defined as a score of ≥5/9 positive tests on the Beighton score measured in early pregnancy. Primary outcome was evening pain intensity in gestation week 30, measured by a 100 mm visual analogue scale. We applied linear regression analyses to estimate age-adjusted unstandardized beta coefficients. Results: Evening pain intensity was similar among women with Beighton score ≥ 5/9 and women with Beighton score < 5/9 (age-adjusted mean difference 2.8 mm; 95% CI: -9.2 to 14.9 mm). Women with Beighton score ≥ 5/9 and pre-pregnancy body mass index ≥ 25 kg/m², reported higher evening pain than women with Beighton score < 5/9 and pre-pregnancy body mass index <25 kg/m² (age-adjusted mean difference 28.7 mm; 95% CI: 14.3-43.1 mm). Conclusions: Overall, evening pain intensity was similar among pregnant women with and without generalized joint hypermobility. However, women with a combination of generalized joint hypermobility and body mass index ≥25 kg/m² reported higher evening pain compared to women with normal joint mobility and body mass index <25 kg/m², suggesting that body mass index may modify the association. The estimates could be imprecise due to the small study sample, and our findings should be interpreted with caution.

Nausea and vomiting in pregnancy - association with pelvic girdle pain during pregnancy and 4-6 months post-partum

Background

To better understand previous associations reported regarding nausea and vomiting in pregnancy (NVP) and pelvic girdle pain (PGP), an investigation into timing of symptom onset for NVP and PGP in pregnancy, as well as the association of NVP with PGP 4-6 months post-partum was performed. We hypothesised that women with NVP symptoms would be most susceptible to experiencing persistence of PGP post-partum.

Methods

Fifty two thousand six hundred seventy-eight pregnancies from the Norwegian Mother and Child Cohort Study were analysed regarding nausea, vomiting, pelvic girdle pain, and health outcome data collected from questionnaires answered between gestation weeks 15, 20, 30, and 6 months post-partum. Logistic regression was used.

Results

Women experiencing NVP and PGP together (6.9%) were heaviest in the sample, youngest at menarche and had highest proportion with education ≤12 years. The primiparous women in this group had the lowest timespan from menarche to pregnancy. Women with nausea alone (NP) and NVP had higher odds of PGP 4-6 months post-partum (adjusted odds ratio, aOR = 2.14, 95% CI 1.70–2.71, and aOR = 2.83, 95% CI 2.25–3.57, respectively), compared to symptom-free women. NP/NVP symptoms appeared early in the first trimester, while PGP symptoms appeared later in pregnancy. Women with longer durations of nausea and/or vomiting had a higher proportion of PGP compared to shorter duration women.

Conclusions

Women with NP and NVP had increased odds of PGP 4-6 months post-partum, and women with a long duration of nausea and/or vomiting had a higher proportion of PGP than women with shorter duration, both during pregnancy and 4-6 months post-partum. This finding suggests a synergistic relationship between NP/NVP and PGP.

Does progestin-only contraceptive use after pregnancy affect recovery from pelvic girdle pain? A prospective population study

Objective

To estimate associations of progestin-only contraceptives with persistent pelvic girdle pain 18 months after delivery.

Methods

Prospective population based cohort study during the years 2003–2011. We included 20,493 women enrolled in the Norwegian Mother and Child Cohort Study who reported pelvic girdle pain in pregnancy week 30. Data were obtained by 3 self-administered questionnaires and the exposure was obtained by linkage to the Prescription Database of Norway. The outcome was pelvic girdle pain 18 months after delivery.

Results

Pelvic girdle pain 18 months after delivery was reported by 9.7% (957/9830) of women with dispense of a progestin-only contraceptive and by 10.5% (1114/10,663) of women without dispense (adjusted odds ratio 0.93; 95% CI 0.84–1.02). In sub-analyses, long duration of exposure to a progestin intrauterine device or progestin-only oral contraceptives was associated with reduced odds of persistent pelvic girdle pain (P_trend = 0.021 and P_trend = 0.005). Conversely, long duration of exposure to progestin injections and/or a progestin implant was associated with modest increased odds of persistent pelvic girdle pain (P_trend = 0.046). Early timing of progestin-only contraceptive dispense following delivery (≤3 months) was not significantly associated with persistent pelvic girdle pain.

Conclusions

Our findings suggest a small beneficial effect of progestin intrauterine devices and progestin-only oral contraceptives on recovery from pelvic girdle pain. We cannot completely rule out an opposing adverse effect of exposure to progestin injections and/or progestin implants. However, the modest increased odds of persistent pelvic girdle pain among these users could be a result of unmeasured confounding.
