what is target population in obg

In OBG (obstetrics and gynecology), “target population” usually means the specific group of women a study, guideline, or health program is meant to apply to.

Simple definition (clinical/research use)

In research or exam language, the target population in OBG is:

The clearly defined group of patients (by pregnancy status, age, parity, condition, etc.) to whom the results of a study or the effect of an intervention are intended to apply.

Examples in OBG context:

• Pregnant women between 24–34 weeks at risk of preterm birth (e.g., for a study on antenatal steroids).
• All women of reproductive age attending a family planning clinic.
• Postmenopausal women with abnormal uterine bleeding.
• Pregnant and lactating women, treated as a special target population because of their physiological status.

So, whenever you read a paper or guideline in obstetrics and gynecology, ask:
“Which exact group of women are they talking about?”
That group = the target population.
