According to the World Health Organization (WHO), labor in pregnancy is defined by regular and painful uterine contractions that cause progressive dilation and effacement of the cervix.
Understanding WHO's Definition of Labor
WHO's definition is crucial for recognizing the start of true labor and differentiating it from other pre-labor discomforts. Here's a breakdown:
- Regular Uterine Contractions: These contractions occur at consistent intervals, and the time between them gradually shortens. They also become stronger and last longer as labor progresses.
- Painful Contractions: These are not just mild tightenings; they are noticeably painful, enough to require focused attention or active coping strategies.
- Progressive Dilation of the Cervix: The cervix, which is the opening of the uterus, gradually widens (dilates) to allow the baby to pass through.
- Effacement of the Cervix: The cervix also thins out (effaces) to become more receptive to opening.
WHO on Normal Birth
The WHO also defines a normal birth as one that:
- Is spontaneous in onset.
- Is low-risk at the start of labor.
- Remains low-risk throughout labor and delivery.
This definition emphasizes the importance of allowing labor to progress naturally, without unnecessary interventions, whenever possible.
Key Differences in Early Pregnancy Symptoms and Labor
| Feature | Early Pregnancy Symptoms | Labor |
|---|---|---|
| Contractions | Irregular, often painless, may come and go | Regular, painful, increasing in intensity and frequency |
| Cervical Changes | No dilation or effacement | Progressive dilation and effacement |
| Pain | Mild discomfort, potentially related to other changes | More intense and consistent |
Importance of WHO Guidelines
Following WHO guidelines helps healthcare providers to:
- Properly identify when labor has begun.
- Distinguish between true labor and false labor.
- Ensure that care is patient-centered and evidence-based.
- Promote a positive and safe birth experience.
