Striae gravidarum in primiparae.

Area of Science:

• Obstetrics and Gynecology
• Dermatology
• Public Health

Background:

• Striae distensae (stretch marks) are common during pregnancy, causing significant cosmetic concern for many women.
• Previous studies on factors associated with striae gravidarum have yielded conflicting results.

Purpose of the Study:

• To determine the prevalence of striae gravidarum in first-time mothers (primiparae).
• To identify independent risk factors associated with the development of striae gravidarum.

Main Methods:

• An observational study analyzed 324 primiparae within 48 hours of delivery.
• Data collection involved questionnaires and physical examinations, recording 17 variables including striae severity.
• A pilot study in 1999 and a 4-month assessment in 2000 included 309 women after exclusions.

Main Results:

• Over half (52%) of primiparous women developed striae gravidarum, with 12% experiencing severe cases.
• Low maternal age was the most significant risk factor (P < 0.0001); 20% of teenagers had severe striae.
• Other significant factors included BMI > 26, weight gain > 15 kg, and high neonatal birth weight.

Conclusions:

• Maternal age, BMI, weight gain, and neonatal birth weight are independently linked to striae occurrence.
• Teenagers represent the highest-risk group for developing severe striae gravidarum.
• These findings warrant further investigation into the underlying pathomechanisms of striae.
