IUD use after 40 years of age

Area of Science:

• Reproductive Health
• Gynecology
• Contraception

Background:

• Intrauterine devices (IUDs) are a common form of long-acting reversible contraception.
• Understanding the safety and efficacy of IUDs in different age groups is crucial for patient counseling.
• Previous studies have not extensively detailed long-term IUD use in women over 34.

Purpose of the Study:

• To compare the outcomes of intrauterine device (IUD) use in women over 34 versus those under 35 at the time of insertion.
• To assess differences in demographic characteristics, side effects, and removal rates between the two age groups.

Main Methods:

• A comparative study involving 163 IUD acceptors aged 35 and older and 321 acceptors younger than 35.
• Data collected on demographics, parity, abortion history, and IUD-related side effects over a 9-year observation period.

Main Results:

• Older IUD acceptors (≥35 years) were less educated, more often married, had more children, and a higher history of induced abortions.
• Over 9 years, the older group exhibited fewer IUD removals and fewer side effects in the final year of use.
• At follow-up, 161 women were ≥40 years old, and 323 were <40 years old.

Conclusions:

• Women over 34 using IUDs demonstrated favorable outcomes with fewer removals and side effects compared to younger users.
• Long-term safety and the specific considerations for hormone-releasing IUDs in older women require further investigation.
