Abstract | STUDY QUESTION: SUMMARY ANSWER: WHAT IS ALREADY KNOWN:
Pelvic girdle pain severely affects many women during pregnancy. Smaller studies have suggested that hormonal contraceptive use is involved in the underlying mechanisms, but evidence is inconclusive. STUDY DESIGN, SIZE, DURATION: A population study during the years 1999-2008. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 91,721 pregnancies included in the Norwegian Mother and Child Cohort Study. Data were obtained by two self-administered questionnaires during pregnancy weeks 17 and 30. MAIN RESULTS AND THE ROLE OF CHANCE: LIMITATIONS, REASONS FOR CAUTION: The participation rate was 38.5%. However, a recent study on the potential biases of skewed selection in the Norwegian Mother and Child Cohort Study found the prevalence estimates but not the exposure-outcome associations to be influenced by the selection. WIDER IMPLICATIONS OF THE FINDINGS: STUDY FUNDING/COMPETING INTEREST(S): The present study was supported by the Norwegian Research Council. None of the authors has a conflict of interest.
