When early labour takes a long time
Karin’s PhD research looked at how common a long early phase of labour is, how women experience it and the care they get, and what care they want. Here is what the studies found, and where the evidence ends.

What the study asked
How common is a long early phase of labour (the latent phase), and how do women experience it and the care they get? Karin also tested a questionnaire that measures women’s experience of early labour, and asked first-time mothers what care they want when early labour is long.
How it was done
Birth records of 1,343 births and questionnaires answered by about 750 women at one hospital in western Sweden, and interviews with 16 first-time mothers. The latent phase was counted as prolonged when it lasted 18 hours or more, using the time each woman herself said labour started.
What the research found
A long early phase is more common than previously thought when women’s own account of when labour started is used. It happened in almost one in four births (23%), and in 29% of first-time mothers. Earlier research had reported 5 to 6.5%.
Women with a long early phase were more likely to have interventions, such as having their waters broken or labour sped up, and more often had an emergency caesarean.
For first-time mothers, a long early phase was also linked to more assisted births, where the baby is helped out with a ventouse (vacuum cup) or forceps.
Women with a long early phase rated their care lower and their birth experience more negatively. This was clearest for first-time mothers, who rated six of ten areas of care lower, against one of ten for women who had given birth before.
Women who were unhappy with their phone call to the maternity unit, or with not being admitted in early labour, felt more distress and rated their care lower. First-time mothers with a long early phase wanted a welcoming midwife, care adapted to them, and information that prepared them, and their need for support grew the longer it lasted.
The questionnaire worked well for measuring how women experience early labour, and can be used to evaluate early labour care.
What it can mean for you
If early labour feels long, you are not alone, and it is common. How you are listened to and supported in early labour can influence how you experience your birth. It is fine to call your maternity unit with questions.
Where the evidence ends
These studies describe patterns and links. They do not show cause and effect. They come from one hospital in Swedish maternity care, and results may differ elsewhere. When labour started was based on what each woman reported.

How this connects to Omaia
Karin’s published studies were not about Omaia, and their results say nothing about Omaia’s effect. We share them because they show the knowledge the research group brings to the planned Triple Helix programme.
- Omaia did not fund, design or run these studies.
- Karin owns the findings and approves how we describe them.
- Omaia’s own evaluation is the planned Triple Helix programme.
