Women with spontaneous onset of labour, living in a Swedish county, were recruited two months after
birth, to a cross-sectional study. Women (n = 829) completed a questionnaire that investigated socio-demographic
and obstetric background, birth outcome and women’s feelings and experiences of birth. The prevalence of
prolonged labour, as defined by a documented ICD-code and inspection of partogram was calculated. Four groups
were identified; women with prolonged labour as identified by documented ICD-codes or by partogram inspection
but no ICD-code; women with normal labour augmented with oxytocin or not.
